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!

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!

I’ve made it twice now, very tasty. Just wondering if I could use honey instead of maple syrup? We don’t usually have maple syrup in the house but usually have honey. Thanks!
Hi Karla! Hooray for a tasty sourdough loaf! You can use honey instead of maple. Several makers have commented they’ve had success with it!
Hi Traci,
I followed your recipe exactly, used the same brand of bread flour. But the inner part seems dense rather than fluffy, the 2 times that I have tried. The crust is fine, though. Also, the dough seems a bit sticky even after 3 sets of stretch and pull. Suggestions please?
Hi Audarya! I’m sorry to hear your bead is dense. My first thought is your starter. Did it pass the float test? Also, I’m curious about bulk fermentation… at what temperature, and is the dough fully doubling during bulk? Keep us posted!
About the dough being sticky… hold off a bit of water (two to three tablespoons) next time and compare how the dough feels and bakes up.
What would the vegan recipe for this bread look like? And is sprouted wheat an acceptable substitute for the whole wheat flour?
Hi Robert… the images for this recipe is of a vegan loaf. I always use homemade cashew milk, but you can use your favorite plant milk. I’ve never baked with sprouted wheat but a quick google search landed me on Cooks Illustrated where they said you can sub sprouted wheat for whole wheat. Lmk if you give the loaf a go!
Thanks for the info. I am going to try if out this weekend with sprouted flour.
Have you tried baking this loaf in a covered pan?
Hi Robert! I’ve not attempted baking this loaf in a covered pan. Keep us posted on your sprouted flour bake!
I made it today and it made great turkey Rueben paninis. I always up the whole grains, so I used 200 grams of whole wheat, part of which was wheat germ and 200 grams of bread flour. I didn’t sprinkle on oats because they often fall off when slicing bread. I used 1% milk because that was all I had.
Hi Debra! Thank you for your note and giving the sourdough a go! Rueben paninis sound like a delicious way to enjoy this bread!
I just made this recipe but my loaf isn’t as tall as yours. I must’ve done something wrong. I let it rise in the pan until it was about an inch over the rim. Smells divine though.
Hi Glenda! It sounds like maybe your starter may have not been quite ready? Did you start with a doubled in size, active starter? Please let me know if you have any questions. I hope you enjoy the bread!
This must be the best sourdough loaf I’ve made. I did play fast and loose with your method, as I do, as I was too tired to bother to start it the night before. Instead of leaving 8 hrs and folding again, I did it an extra 3 times beforehand and put straight in tin. Left in my conservatory for 6 hrs and was huge. Also used 200g wholemeal nstead of 100, as I like the fibre. Tastes great. (Didn’t wait an hour to eat some either;))
Hi Stephanie! Thank you for your note and sending a smile. SO happy to hear!
Wow, this was delicious! It’s a lovely dough to work with, and I love the overnight room temp proof. I have a chilly house too, so it was nice to go to bed knowing it wouldn’t over-proof! I used white whole wheat flour and had no trouble with the dough.
Hi Allison! SO happy to read your note and that the sourdough is a success! Thank you for your tip on the white whole wheat flour (a flour I love).
I love this bread! I have made it 3 times in the last two weeks. I make mini loaves or buns with it but today I doubled the recipe and made 2 larger loaves and 2 mini loaves. I only have all-purpose flour so that’s what I used. I have made bread before so I added a bit more flour but it was still very tacky. My kitchen is on the cool side so it takes longer to rise (12 hrs overnight then about 4 hrs for the second rise) but it turns out yummy every time. Definitely a keeper!
Hiii Liza! Thank you for your note, giving the sourdough a go and sharing your tips on the flour and mini loaves! SO happy to hear you’re enjoying the bread.
After being delighted with your fluffy Sourdough banana muffins I am also delighted by this Maple oat sourdough sandwich bread recipe. I did use light brown sugar as that was all I had, I used 1 cup of King Arthur unbleached organic bread flour, 1/2 cup of Red Mill 100% stone ground whole wheat flour and added 1/2 cup of bourbon soaked golden raisins (just because). My final proofing took over two hours but the ultimate end result was very good. The taste and texture are delightful. Thank you once again for you clear directions from the beginning process to the end. I am no longer intimidated by making sourdough bread, as this has been my first time encounter…and I am old.
SO happy to hear of your success, Jean! Thank you for sharing your tips (that’s the combination of flours I use too)! Way to go you for jumping in to sourdough bread making… You’re doing it!!
I made this loaf and am so pleased with the result. I am still learning the sourdough process but this loaf was perfect, not sticky and rose beautifully and tastes delicious.
Hi Lyn! Thank you for your note of success and hooray for enjoying the sourdough process – isn’t it so satisfying?
