How to Make Authentic Sourdough Sandwich Bread (2022)

by Heather

Ah, sourdough sandwich bread… The perfect marriage between deliciousness and convenience.

Sourdough sandwich bread uses the same recipe and initial process as my Simple Sourdough recipe, but is shaped differently and baked in a bread pan or Pullman pan. In this post we will talk about the benefits of sourdough, sandwich loaves vs boules, what type of pan to choose, and much more.

How to Make Authentic Sourdough Sandwich Bread — Leavenly

Why sourdough?

Sourdough bread is superior to store-bought bread in nearly every way. When people think of bread, they tend to think of that which uses commercial, or quick rise, yeasts. However, this type of bread has only existed for just over 160 years.

Sourdough breads are made with wild yeasts and bacteria. Three basic ingredients – flour, water, salt – come together in a beautiful symbiotic rhythm to rise the bread naturally, as has been done for thousands of years. The yeast and bacteria that exist on the flour grain and on the bakers hands get kick-started once the water is added to the flour. They begin digesting the flour, and a by-product of this digestion is carbon dioxide. The CO2 creates bubbles in the dough, which gives the bread its rise. Some bacteria even digest gluten, creating lactic acid which brings the sour to the sourdough. (An interesting side note: many people who are gluten-sensitive are actually able to eat sourdough with no digestive issues – this is due to that breakdown of the gluten protein, making it gentler on sensitive stomachs.)

Sourdough sandwich bread vs boules

When people think of artisan sourdough, they think of a boule. A boule (French for “ball”) is a round loaf of bread, characteristic of artisan bakers. However, sourdough can take many shapes, from an oval shape called a batard, to baguettes… The list goes on.

A sandwich loaf is a convenient shape for those who enjoy making sandwiches and toast with sourdough bread. The shape is like conventional store-bought sandwich bread, but contains much more nutrition and much fewer chemicals. 

Some bakers do all of their sourdough as a sandwich loaf, simply because they feel that it’s easier to bake sourdough in a pan. They’re on to something… When overfermented, it’s not a big problem as with baking a boule or a batard. The pan provides the structure for the dough, so even overfermented dough can bake up beautifully in a loaf pan. 

Pullman pan vs loaf pans

A traditional loaf pan – the one you likely have in your kitchen – is short, and its walls slant outward slightly at the top.

A Pullman pan has tall, straight walls that produce that familiar sandwich bread shape that we all love. Of course, baking in a loaf pan is fine, but you will have to make some adjustments, as Pullman pans are larger and can accommodate more dough. 

It’s also important to know the size of your Pullman pan. This photo shows a 13” x 4” x 4” Pullman pan, but the recipe below uses two 9″ loaf pans. See Recipe Modifications below for some tips on using different size pans.

Adding extra ingredients

True artisan sourdough consists of just three ingredients: flour, water, and salt. But that’s not to say you can’t add additional ingredients!

Milk – Milk works as a dough conditioner, creating a softer and fluffier texture. It also helps with rise during proofing, and generally creates better oven spring. I like to replace about 50g of water with whole milk when I make my sourdough sandwich loaves.

Honey – The addition of honey creates a sweeter bread, and honey also works to prevent the bread from drying out as quickly. Simply add up to 25g of honey to this recipe.

Oats – For added nutrition and improved mouth-feel, oats are a great addition to sourdough sandwich bread. To add oats, it is imperative that they are soaked through, or else they will absorb the moisture from your dough, resulting in dry bread that doesn’t behave as it should. I recommend soaking about 60g of oats in about 80g of water overnight before mixing your dough, then adding with the salt and water after the autolyse is completed. 

Adding Toppings to Sourdough Sandwich Bread

For a simple and beautiful crust, simply brush with egg white before baking. This will make the crust a nice dark brown, and add some crispiness, too.

For a decorative crust, try sprinkling rolled oats, sesame seeds, poppy seeds, or whatever topping you’d like onto your dough after you brush with egg white, just before it goes in the oven. I personally love the look of rolled oats on the top of sandwich bread; it just makes it that much more appealing!

To Score or Not to Score?

There are varying opinions on whether or not a sandwich loaf should be scored. Some folks say no, that it compromises the strength of the dough and therefore its oven spring potential, while others say it does the opposite and promotes better rise, plus looks better. Scoring your dough is a matter of personal preference, in my opinion. I don’t score mine, but you may like to score yours, and neither are wrong!

If you want to score your sourdough sandwich bread, simply slash straight down the middle of the dough after you brush on your egg white.

Recipe modifications

This sourdough sandwich bread recipe makes two 9″ loaves. Here are some adjustments you can make if you want more, less, or larger loaves:

  • If you only have one 9″ pan, simply cut the recipe in half, or shape the remaining dough into a boule or batard and place into a banneton
  • If you have one 13″ pan, use these measurements: 550g AP flour + 60g WW flour + 458g water + 13g salt + 122g leaven
  • If you’d like more than two loaves, multiply the recipe by 1.5 or 2, depending on how many pans you have

Without further ado, let’s get started!

Servings 2 9″ loaves


  • 830 g all purpose flour or bread flour
  • 90 g whole-wheat flour
  • 690 g water
  • 20 g salt
  • 184 g leaven


Day One: Leaven Day

  • Before bedtime, build your leaven. Weigh 100 grams of lukewarm water in a mason jar and add 50 grams of your healthy, active starter, which you fed this morning (8-12 hours ago). Don't use freshly fed starter, it is not mature enough. 
  • Swirl the jar to incorporate the starter. Add 50 grams whole wheat flour and 50 grams white flour (all-purpose or bread flour). Stir with a butter knife or spatula until mixed well. Make sure no dry flour remains.
  • Place the lid lightly on the jar – don't screw it on! – and leave on the counter to ferment overnight.

Day Two: Mix Day

  • Place your mixing bowl on the scale and weigh 640g of the water (save 50g) and 184g of your leaven. Using your hand, incorporate the leaven a bit by squeezing it through your fingers. Use the rest of your leaven in discard recipes, or simply throw away.
  • Add both flours and mix together with your hand. Mix until you don't see any more dry flour in the bowl. The dough will become sticky, so it's useful to keep one hand clean. Dunk your clean hand in water, and remove the sticky dough from your other hand. Then dip your dough spatula in water and scrape the edges of the bowl, making it as clean as possible.
  • Cover the bowl with a clean kitchen towel or plastic and let the dough rest for 30 minutes. This is called the autolyse, which allows the flours to absorb the water, activating the enzymes which begins the gluten development. This step is critical and cannot be rushed.
  • After the autolyse, sprinkle the salt over the dough and then add the remaining 50g of water. Poke your fingers into the dough to press some salt deep inside, then fold over itself about a dozen times or so to incorporate the salt. Cover the bowl again; the bulk fermentation has begun. Set your timer for 30 minutes.
  • The bulk fermentation takes four hours. During the first two hours of the bulk fermentation, the dough must be folded four times, or every 30 minutes. This is similar to kneading but is much more gentle to preserve the natural gases that become captured in the dough, and is much easier on the baker.
  • To fold the dough, first imagine your bowl as a compass: the edge furthest from you is north, the right edge is east, the closest edge to you is south, and the left edge is west. Dip your hand in water and reach under the dough at the east point. Grabbing it gently but firmly, pull the dough out to the east and then fold it over itself toward the west. Rotate the bowl a quarter-turn, and repeat. Do this for each "corner" of your compass, then cover with a kitchen towel. These are called stretch-and-folds.
  • Set your timer for 30 minutes, and repeat the process three more times.
  • Your dough now gets to rest, covered and untouched, for 1 1/2 – 2 hours. During this time, flavor and strength is developed, so don't rush this step.
  • After the bulk fermentation, pull all the dough onto a floured work surface using a dough spatula. With your bench knife, cut the dough into two even pieces.
  • The pieces now need to be pre-shaped. Working with one piece at a time pull the west side of the dough out and fold it toward the east. Then pull the east side out and fold it over and toward the west. Then grab the north side and fold it up toward the south, then roll the dough loosely toward the south and let rest on its seam. Do the same for the remaining piece, then lightly dust both with flour and cover with a kitchen towel. This prevents a skin from forming on the outside of the dough. Let rest for 30 minutes. This is called the bench rest.
  • For the final shaping, care must be taken not to deflate the dough. Gently rub off any excess flour – the top of the dough will become the inside of the loaf, so you don't want any extra flour inside. First, gently pull out on the corners to make a very rough rectangle of dough. Just as in the pre-shaping, pull the west side of the dough out and fold it toward the east. Then pull the east side out and fold it over and toward the west. Stretch the north side up and fold down toward the south, then roll the dough down like you're rolling a yoga mat. You will hear and feel gas bubbles popping; this is okay. Repeat for the remaining piece.
  • Lightly grease each bread pan with olive oil or butter, and place each dough roll into the pans. Now begins the final rise. Cover with plastic or place in a grocery bag, and put both pans into the refrigerator overnight. This is called cold-proofing. The plastic is used to prevent fridge odors from absorbing into the dough. The dough will continue to ferment slowly. You can leave your dough in the fridge for up to 48 hours, but I recommend baking around 18 hours if possible.

Day Three: Bake Day

  • In the morning, create a steam tray. Place two or three old kitchen towels in a cookie sheet and soak them under the faucet, filling the pan about halfway up with water. Place your steam tray on the lowermost rack of the oven and preheat at 400*F for at least 30 minutes. KEEP AN EYE ON THE LEVEL OF WATER IN YOUR STEAM TRAY. If the water boils dry, your towels will burn. To add more water, use hot tap water and pour from a watering can or a large pitcher.
  • When your oven is preheated and steamed, pull the bread from the refrigerator and remove the plastic. Brush the tops with egg white if you'd like a softer, dark brown crust. Add poppy seeds, rolled oats, or any other toppings on the egg wash if desired. Place bread pans in oven and bake uncovered with steam for 20 minutes.
  • After 20 minutes, carefully remove the steam tray and vent the oven (simply allow the oven door to be opened for 30-60 seconds so the steam can dissipate). Rotate your bread pans 180*, close the oven door, then bake 30-35 minutes more.
  • Remove the bread from their pans by tipping upside down, then place loaf directly on oven rack and bake for 5 minutes more.
  • Remove and allow to cool for at least two hours. Slice and enjoy!

I am trying to get an understanding of the different sizes of pans and the amount of dough that is appropriate. Some clarification please. In the beginning you say, “The recipe below utilizes a 13” x 4” x 4” Pullman pan.” Then under recipe modifications you say, “This sourdough sandwich bread recipe makes two 9″ loaves”. And it goes on to say, “If you have one 12″ pan, use these measurements: 550g AP flour + 60g WW flour + 458g water + 13g salt + 122g leaven”. What I have seen so far is that the Pullman pans seem to be more narrow and deeper than loaf pans. So maybe a 13″ Pull man, or 2 – 9″ loaf pans can take the same amount of dough? And the 12″ pan? Is that perhaps a loaf pan too, so that is why you decrease the ingredients? By the way, you did really well with your video, especially for a first time. It felt very “real”, and you shared with us your fellow bread bakers. I like it. Thank you.

Heather January 9, 2021 - 1:29 pm

Hi Peg, those sections were unclear so I’ve re-written them, thanks for the heads up.
To clarify, there is a 9″ and 13″ Pullman pan (at least the ones made by USA Pan), and there are 9″ loaf pans. I’m not sure where the 12″ came from, that was an unfortunate typo 😉
Glad you were able to check out the FB Live video on Sourdough Mamas, and I appreciate your feedback!

Helga March 24, 2021 - 2:49 pm

Yes, to Peg’s point. I wish I had read this prior to using your suggested measurements for a 13″. It’s way too little. My loaf came out like a submarine with flat ends. I’m sure it’ll taste delicious still but no square sandwiches from this loaf 😫

Heather November 6, 2021 - 3:18 pm

Ah no! I’m so sorry. I’ll edit the post and find a way to make this more clear!

Jon Lacey January 8, 2021 - 11:22 pm

Day 3, item 2. I think you mean ‘pull the bread from the fridge
Great first video but I would like to know why you use tea towels in your steam pan, why not just water?

Heather January 9, 2021 - 1:24 pm

Nice catch, Jon! I’ll make that change now.
I use tea towels on my pan to slow the release of the steam and make that water last a bit longer!

Jennifer January 13, 2021 - 10:31 pm

Hi Heather. Thanks so much for your blog, your website, your video, the Facebook group; all have been incredibly helpful. I live at 7000’ (in Eagle, CO – about 100 miles west of you) and was having a tough time – think hockey puck- until I found your high altitude recipe. It has been a game changer for me.
To make sandwich bread should I use the recipe in this post or use the High-Altitude recipe?
Again – thanks for all you do!!!!

Heather January 14, 2021 - 7:33 am

Thanks for the lovely comment, Jennifer! I’m going to make a high-altitude sandwich bread recipe, but in the meantime, I would combine the two recipes. Use the high-altitude method up until the shaping, and then follow the sandwich bread recipe!

Melissa Dye January 14, 2021 - 2:57 pm

If I wanted to use the 2 day method for this sandwich bread, would you suggest following the same steps as in the boule recipe? Also, wanted to mention that I’m in Monument, Colorado (7300 ft) and I’ve been following your high altitude recipe for months now with great success. Thanks!

Heather February 1, 2021 - 3:17 pm

Hi Melissa, yes, you would. Good question! And thanks for the High-Altitude recipe feedback! 🙂

Shirley April 26, 2021 - 10:56 am

Good instructions. I haven’t made any bricks since following your format. Do you follow the same instructions with rye bread?

Heather July 7, 2021 - 1:26 pm

I don’t see why not, Shirley! I’d give it a try!

Evelyn G Kimbrell January 15, 2021 - 3:55 pm

I just watched the video on YouTube, and made this comment there:
I loved watching this! Also, one of the audience questions was about cleaning up afterwards; I play with ceramics, also, and found that using a clay scraper on the bowl obliterated the crusties and leftovers beautifully. Get them wherever clay tools are sold. They are either plastic or metal and are flexible. Works like a charm!

Heather February 1, 2021 - 3:20 pm

Hi Evelyn, thanks for the comment and the great suggestion! 🙂

Such a simple recipe that comes out so great! Thank you for the wonderful post and recipe, my family can’t get enough!

Mary Unitis January 29, 2021 - 7:14 pm

Hi Heather!
Can I leave the lid on the Pullman bread pan, and if so, when would I put it on? I would like to have a square sandwich loaf.

Heather February 1, 2021 - 3:16 pm

Hi Mary! Yes, you can put a lid on the Pullman pan when it goes into the oven! This creates steam within the pan, so a steam tray isn’t necessary. When the recipe states to remove the steam tray and vent the oven, simply take off the lid! 🙂

Kathy Melish February 2, 2021 - 3:12 am

I think I must have screwed up because the top of the sandwich loaf is really high and misshapen. I didn’t score the loaves so maybe that would have helped. I will post a picture on FB. It does taste great. Thanks for all your advice!

Heather February 2, 2021 - 3:02 pm

I wouldn’t call that a screw up, I’d call it delicious learning! Scoring may have helped, but it’s possible there were some large air bubbles just under the surface of your dough. If you can see them as you’re shaping, I recommend pinching them to remove the air! Thanks for sharing, Kathy!

Shannon April 22, 2021 - 1:33 pm

Question. Vent the oven? Am I leaving the door open the rest of cooking time or just while removing the steam tray?

Heather November 6, 2021 - 3:39 pm

Just while removing the steam tray. Leave the door open for 30-60 seconds!

CJ April 23, 2021 - 8:09 pm

I’m trying to decide what exactly you mean by “venting the oven”. I’m super literal so I take it to mean to crack (vent) the door and leave it cracked for the rest of the bake time (after the 180 degree rotation) but a little voice is causing me to doubt that. I’ve gotten super comfortable with boules and battards (using your perfect Simple Sourdough Recipe – thanks for that!!!) but I’m a bit intimidated by this sandwich bread. PS: you are appreciated!!!

Heather November 6, 2021 - 3:40 pm

Great question! Simply leave the door open while you remove the steam tray for 30-60 seconds.

Iris May 13, 2021 - 1:06 pm

To make the basic sourdough bread can you use the sourdough starter made with potato flakes, sugar and water ?

Heather July 7, 2021 - 1:16 pm

I’m not familiar with that technique, but I would say you can use any starter that is created to make sourdough bread! I recommend one made from flour and water to keep it simple.

Molly June 7, 2021 - 7:08 am

Does the flour measurement include the 50 grams of AP and whole wheat flour required for the levain, or is that separate and not mentioned until he ingredients list?

Heather June 25, 2021 - 9:56 am

Correct, that’s separate 🙂

Mike Coleman August 2, 2021 - 9:06 am

Hi Heather,
I’m just reading this recipe to bake this Thursday (Tuesday now here in Australia).
After the final shaping and adding the dough to the pan/tin do you add it seam side up or smooth side up?

Heather November 6, 2021 - 3:53 pm

Seam side down, Mike! Good question.

Rosemary Gregory August 5, 2021 - 11:14 am

Cannot wait until starter matures and I can make this recipe. I have two 8.5 inch pans. Would it be possible to use them or do I need to “invest” in the two 9 inch pans. While I would prefer to use what I already have, I don’t want to sacrifice the outcome of the bread. Am loving reading all your articles – not getting a lot of housework done, though!

Heather November 6, 2021 - 3:53 pm

Your 8.5″ pans are perfect!

Joe Rex September 14, 2021 - 9:18 pm

I often like to add seeds or cracked wheat to my breads. The cracked wheat is so not an issue with hydration as I presoak it, however if I wanted to add some say flaxseed, sunflower seats, oats etc would I need to add additional water and or starter?

Heather November 6, 2021 - 4:17 pm

Oats should be cooked, and flaxseed can also be soaked! Sunflower seeds are A-OK. 🙂

Catherine Johnson October 6, 2021 - 8:20 am

Hi Heather, First of all I want to thank you. Your recipes are so easy to follow and for an ex cook and baker who just turned 78 I need instructions that are easy to follow and don’t get to fancy with the wording. I just pulled my bread out of the oven. One domed high in the middle and cracked and the other one didn’t rise as much. I need to know if I should leave them to ferment longer or if maybe I left them too long in the refrigerator. I put them in the refrigerator at four yesterday afternoon and started baking at 7 this morning. Both loaves are really dense.

Heather November 6, 2021 - 4:33 pm

Thanks Catherine! My first thought, if you’re dealing with dense bread, is that maybe your starter isn’t active enough. Could that be the case?

Courtney October 12, 2021 - 8:02 pm

I have a kinda odd question. So you recommend putting the baking sheet with towels and water for steam… would I be able to put my 9inch loaf pan in the Dutch oven and bake it that way? To retain the steam?

Heather November 6, 2021 - 4:36 pm

Interesting idea! I don’t see why not, if it will fit… Please let us know what happens!

Meghan November 8, 2021 - 10:20 am

This is what I plan to do. My dough is in bulk ferment right now and I have done other sourdough sandwich loaves this way successfully. I place the loaf tin into my preheated Dutch oven, toss an ice cub in beside it, lid on, and into the oven with the lid for the first 20 mins.

Marianne Ogg October 13, 2021 - 5:47 am

Hey, I’m excited to try this recipe this week! When you bake it, after you take the steam tray out, do you leave it vented the rest of the baking time? What about the last 5 mins without the pan?

Heather November 6, 2021 - 4:37 pm

I will clarify this statement because it’s causing a lot of confusion, so I’m sorry for that! What I mean is, vent the oven as you’re removing the steam tray, keeping the door open for 30-60 seconds to let the steam dissipate, then close it again.

Savannah November 3, 2021 - 10:52 am

Hi, I made this recipe with AP and Bread flour. No wheat. And it turned out short and dense with no rise…was that the problem?

Heather November 6, 2021 - 4:45 pm

Whole wheat flour provides a ton of extra nutrition which results in more microbial activity and therefore improved fermentation, so it doesn’t surprise me that an all-white sourdough didn’t rise well. It’s also possible it was overfermented, but with limited information, I would advise trying with the whole-wheat flour to see what difference that makes for you!

Meghan Baxter December 14, 2021 - 6:26 pm

Well my dough has just finished the bulk fermentation and as I’m getting ready to shape and refigerate overnight, the igniter on our oven went kaput! Has anyone adapted a loaf recipe to the slow cooker or air fryer/mini convection over before? Need some overnight advice! Thanks so much.
