Sourdough Love
There are many sourdough variations, and while I adore a crusty classic or multigrain sourdough, I can never pass up a softer loaf for toast, sandwiches, and French toast.
So I set out to create a softer loaf with earthy flavors in the shape of traditional sandwich bread. This loaf, my Soft Multigrain Sourdough Sandwich Bread and Fresh Sourdough Sandwich Bread are among my favorites. They all stand up to the sandwich test and taste delicious!
This Recipe Is
- made overnight with a short morning proof
- earthy, and lightly sweetened

How to Make Maple Oat Sourdough Sandwich Bread
step by step




The rolled oats are a nice surprise in this dough. They soften as the dough ferments, so they’re barely noticeable in the crumb yet add a soft, earthy flavor to this loaf.




Bulk fermentation (first rise) is complete when the dough no longer looks or feels dense, is tacky, not sticky, is jiggly when the bowl is shaken, and has about doubled in size. You may also see a few large bubbles on the surface of the dough.

How to Shape the Dough






Fitting Sourdough into Your Schedule
When it comes to sourdough, fitting it into your schedule can be achieved through a little strategic planning and, if needed, using a technique I keep in my back pocket for when something comes up and I need to extend the time between mixing and proofing…
…because things come up, right?
Retarding the dough is optional but is a tool for bread bakers to manage the speed at which the dough rises. Retardation is simply the process of placing the dough in the refrigerator to slow down fermentation so the rise takes longer. This is handy for flavor development but also, as a time management tool.
When to Retard the Dough
I do this when I mix in the morning. I just pop it in the fridge for the day, then pull it to room temperature before I go to bed. It’s doubled in size by morning!
During Bulk: for this loaf, retard during bulk to slow down the rise allowing flexibility for when the dough will be shaped, proofed and baked. The dough still needs to double in size during bulk fermentation (first rise), so after refrigeration I pull it to room temperature, and let it finish rising, until it doubles in size. I’ve not tested the limits of this, but up to about 10 hours in the refrigerator generally fits my schedule.

When is the Second Rise (proof) Done?
When the dough has risen in the loaf pan to about 3/4″ – 1″ (2cm – 2.54cm) above the lip of the pan at the center. Have a ruler ready for this part! The amount of time it takes to proof will vary depending on ambient temperature. At 70F (21C) proofing takes about an hour. It can take up to twoish hours in a chilly kitchen (raises hand!).
If you’d like to speed this process along, you can put the loaf in a turned off oven with the light on. Just be sure to remove the loaf before preheating your oven for baking!



Traci’s Tips
- Whole Wheat Bread Flour: this maple oat sourdough sandwich bread calls for whole wheat bread flour, which can sometimes be hard to find. If unavailable, use regular whole wheat flour. The difference is subtle, but whole wheat bread flour yields a little bit stretchier dough and is easier to work with.
- Kitchen Tools: I recommend a digital oven thermometer for monitoring accurate oven temperature and weighing your ingredients using a digital kitchen scale for best outcome (affiliate link).

Overnight Maple Oat Sourdough Sandwich Bread
Ingredients
For the Soaker:
- 1 C (100g) Whole Rolled Oats, plus 2 Tbs for the top
- 1/2 C (105g) Water, room temperature
For the Dough:
- 3/4 C (150g) Sourdough Starter, 100% hydration, previously feed and bubbly
- 1 C (230g) Milk, (nut milk or whole dairy milk) I use 1/2 diluted unsweetened cashew milk – 80F (26C)
- 1/4 C (80g) Maple Syrup
- 1 Tbs (14g) Olive Oil, + more for oiling the pan
- 1/2 C + 1 Tbs (100g) Whole Wheat Bread Flour , (see note**) or whole wheat flour
- 2 C + 3 1/2 Tbs (300g) Bread Flour
- 1 1/2 tsp (10g) Fine Sea Salt
Instructions
For the Soaker:
- Add the oats to a small bowl and pour the water over them. The water wont fully cover the oats – that's okay. Set aside.
For the Dough:
- Mix the Dough: In the evening, whisk the starter, milk, maple syrup and oil together in a large bowl with a fork. Add the flours and salt. First, mix with a fork, the dough will be shaggy. Then mix by hand, mixing, folding and pushing the dough until the flour is fully incorporated and no dry bits are present. It will seem dry at first, but the more you work the dough, the more hydrated it will become. The dough will feel stiff and it will stick to your fingers as you go. Do this for about 3-4 minutes. Use the fork to scrape off the dough on your fingers as much as you can. Cover bowl with a damp tea towel. Set a timer for for 30 minutes and allow the dough to rest for 30 minutes. Now is a good time to feed/refresh your starter.
- Incorporate the Soaker: After the dough has rested, mix in the soaker. To do this, dump the soaker on top of the dough and begin kneading and folding the dough over and on top of itself, incorporating the ingredients of the soaker. Do this for about 2-3 minutes or until the soaker is evenly distributed in the dough. It will seem like a lot of added bits, but as you work the dough and as the dough develops through fermentation, the soaker will incorporate. The dough will be stiff, wet and sticky. Cover bowl with a damp tea towel, set a timer for 30 minutes and allow the dough to rest for 30 minutes.
- Fold the Dough: After the dough has rested, fold the dough. To do this, grab a portion of the dough while it remains in the bowl, stretch it up and fold it over, pressing your fingertips into the center of the dough. You'll notice the dough is a little less stiff and more workable at this point. Repeat, until you've worked your way around the dough. If the dough feels *too* stiff, you can always let it rest another 15 minutes. This is the first fold, and you can stop here and begin bulk fermentation, but If time permits, and optimally, you'll want to repeat this fold two more times as it improves the final dough's structure and crumb. Allow for about 30 minutes between the second and third fold.
- Bulk Fermentation (first rise): After the last fold, cover the bowl with a damp towel and allow to rise overnight at room temperature (see note* on optionally retarding the dough). This will take about 8-10 hours at 70F (21C), but in a cooler kitchen the dough can take up to 12-14 hours to rise – this is the norm in my chilly kitchen 66F (18C). Use the time as a guide and not a determining factor. The dough is ready when it no longer looks dense, is jiggly when the bowl is shaken, and has about doubled in size.
- Shape the Dough: In the morning, and with damp fingertips, coax the dough into a floured work-surface. With moist fingers, take a portion of the dough, gently stretch it towards you and fold it over towards the center, pressing it down gently. Repeat this process until you work the dough all the way around the dough. Using a bench scraper flip the dough over, cover with a tea towel rest the dough for 15-20 minutes. While the dough rests, throughly coat the inside of a 9×5" (23cm X 12cm) loaf pan with olive or coconut oil. Set aside.Flour the work surface and using a bench scraper flip the dough back over. Use the photos in the blog post to help guide shaping. Gently shape the dough into a rough rectangle (sort of a football/oblong shape if you can) by dimpling the dough (think focaccia), to roughly 6" wide and 8-10" long. Fold the dough lengthwise 2/3 over onto itself and crease it firmly using the pinky side of your hand. Fold the 1/3 piece left towards the crease and pinch the seam closed. Fold in the ends, coming in about an 3/4" – 1" and pinch the seam closed. Flip the bread over and rock it back and fourth a bit and gently fluff the ends in. Cover with a tea towel and allow the dough to rest for about 5-10 minutes. Scrape your work surface area of any excess flour and very lightly spritz it with water. Place the dough on the spritz of water (seam side down) and using lightly floured hands, cup the back of the dough and gently pull it towards you until the surface is taught. Gently "fluff" the ends in again if needed to fit into the loaf pan.Once the surface is taut and with one swift move, use the bench scraper to scoop the dough up and, place the dough into the prepared loaf pan. If there's any misshapen edges that need tucking in, use a moist rubber spatula to gently finesse and shape the edges of the dough down into the pan.
- Proof the Dough (second rise): Cover the pan with a damp tea towel and allow the dough to rise until the dough rises to about 3/4" – 1" (2cm – 2.54cm) above the lip of the pan at the center of the dough. The amount of time will vary depending on ambient temperature. At 70F (21C) proofing takes about an hour. In my chilly kitchen, about two hours.Set an oven rack in the center of the oven. Preheat your oven to 450F (232C).
- Bake the Dough: Lightly spritz the top of your loaf with water and sprinkle 1-2 Tbs of Rolled oats over the top. Place the loaf into the oven and then, reduce the oven temperature to 400F (204C). Bake for 45-55 minutes, rotating and tenting the loaf at about 25-30 minutes so it doesn't get too dark. The bread is ready when the internal temperature of the loaf is between 190F – 205F (87C – 96C). When done, transfer to a wire rack. Cool for 10 minutes in the pan, then transfer to a cooling rack. Cool 1 hour before slicing.
- Storage Notes: Sourdough is best consumed on the same day it's baked, but it lasts for 3-4 days stored at room temperature. Store at room temperature cut side down.This bread freezes beautifully. Store baked bread in a freezer bag either whole or sliced for up to two weeks. Thaw at room temperature. This bread can go straight from freezer to toaster to make the most delicious toast!

My bread is delicious, but chewy. Should it be or did I do something wrong?
Hi Gain! Thank you for your note. So happy to hear you’re enjoying the sourdough. But this loaf should be soft, with a somewhat chewy crust. Was it the interior or exterior that was chewy… or both?
This loaf is so delicious! I’ve made it twice and both times it bakes a little lopsided. I think it has to do with my shaping. Any tips how to make it a bit more even?
Hi Mel! So happy to hear! Indeed, it’s the shaping. Here’s something different to try. Instead of folding in 1/3 then again, then folding the ends, try shaping into a rectangle the length of the pan and rolling the dough into a log (like cinnamon rolls). Pinch the bottom seem and transfer it to the pan. I hope this helps and the loaf comes out even next time!
This is DELICIOUS. Pretty sure I did something wrong because my loaf turned out gigantic haha but the bread tastes great. I will make this again! Thank you for sharing!
Hi Maddie! It sounds like you had some amazing oven spring (!!). Thank you for your note. So happy to hear!
I’m always on the lookout for super sandwich bread, as I bake 45 loaves a week to sell at a Farmers Market. This sounded super and is cooling on the counter now. Because I bake in such volume, I use a mixer and it worked fantastic and I didn’t have to stretch and fold. I also divided the dough into quarters and used the Japanese Milk Bread technique on it. It’s looks mighty good! Would love to show you a pic, but don’t know how on this site.
Hi Brenda! Thank you for your note and giving the recipe a go! Would love to try the Milk Bread technique on this loaf – how wonderful! I don’t have photo sharing capability here, but if you’re on IG or FB, you can share there or email me traci@vanillaandbean.com ! I’d love to see!
Hello! If my starter is maintained at 80% hydration, how would you recommend tweaking your recipe? Can’t wait to try!
Hi Jenny! At 80% hydration, I’m thinking you’d need to increase the water in the recipe only slightly. But by how much, I’m not exactly sure. I’m sorry I can’t be of more help.
I’m so excited to try this bread. I put it in the fridge overnight and have it proofing in my warm spot now! I love reading through comments.. next time I’m using honey and adding some seeds!! we love seed bread in our house but it’s so spendy!!
However…. I do not have one large loaf pan but 2 smaller loaf pans so we shall see how that plays out!! I’ll get a larger one when I can.
Cheers!!
Hi Sherice! Thank you for your note and giving the recipe a go. Honey and seeds sound lovely! How’d the smaller loaf pans work out?
Hi Traci,
looks amazing, and would like to try it .
is is ok to change maple sirup to honey, and what is the conversation rate is it 1:1?
thank you
Hi Aniko! Honey will work just fine – same amount, but it may darken the crust a little faster. You may need to tent the bread to protect the crust. Other makers have used it (see comments below) with success. I hope this helps and you enjoy the sourdough!
My absolute favorite bread. Everyone who tries it falls in love!
Awh, thank you for your note and giving the recipe a go Candace! I’m so happy to hear you and those that you’re sharing it with aare enjoying the sourdough. I think it’s the oats that really make this bread so flavorful!
This was my first attempt at traditional loaf of sourdough bread. It was easy to make and turned out great. Mine doesn’t have much air in the crumb but that’s okay for a sandwich loaf. I did think the directions were a little more detailed than necessary but I’ve been baking sourdough for a while now. I’ll definitely make this again.
Hi Dee! Thank you for your note and giving the recipe a go. So happy to hear you enjoyed the recipe!
This is one of my favorite loaves! I used steel cut oats and am so glad I did- it made the bread chewy and hearty. Next time I’ll cut back on the maple syrup. I also added maple extract. Maybe that’s cheating, but it’s very good. I also used almond milk. I fed my starter around 9am, mixed my dough around 5. All of my tests and stretches and folds were done around 7 so I let it bulk rise on the counter all night. Formed into a loaf pan around 6am and by 8, my bread was in the oven baking. My kids love it! Thanks for the recipe. It’s a keeper!
Hooray! Thank you for sharing your notes and success, Kelly! Did you cook the SCO before you added them to the dough? Maple extract sounds amazing!
I didn’t cook them! I boiled the water and let them soak for probably 30 minutes as I did the first steps of the recipe. They get a little soft before you incorporate them, but once the load is baked, the oats add a little soft crunch and texture that is perfect.
Ohhh Thank you for your tip Kelly! Sounds amazing!
Hi Traci. Thanks for this super delicious sourdough recipe. I’m new to the bread baking and sourdough world so am definitely on a learning curve. I have made this recipe several times (have a loaf fermenting on the counter now!) and it is my favorite of all the recipes I have tried so far, and there have been many. I use honey in place of maple since I’m not a big fan of maple flavor. My only issue has been that the loaves have been a bit dense at the bottom, but I’m sure this is not a recipe issue, rather me not having developed a good bakers instinct yet and not hitting the fermentation or proof timing right. Dense on the bottom has been consistent in most of my bakes. Any insight would be appreciated!
Hi Dana! Thank you for your note and enjoying the sourdough. SO happy to hear! With regards to the dense bottom, I’ve not experienced this. However, it seems to be a proofing issue from my quick search online. I’ve read a dense bottom can result when the dough is overproofed. Have you tried the poke test to make sure your dough is properly proofed prior to baking? Wet your finger and gently poke the dough with your fingertip. If it instantly springs back, it’s underproofed. If it doesn’t spring back at all, or only slightly, it’s overproofed. If the dough springs back in slow motion most of the way (but still leaves a slight indent), it’s ready to bake. It’s better to poke early than late. Too, be sure to keep a sharp eye on how high the dough has risen above the rim. Use a ruler and get down low so you can see the actual height next to the rim of the pan. I hope this helps Dana! Please keep us posted!
