This honey oat sourdough features a soft, tender crumb, a gentle honey sweetness, and a rustic oat-coated crust. A small amount of whole wheat flour adds a subtle earthy note without overpowering the loaf.
The dough is softer and slightly stickier than a basic sourdough because of the hydrated oats and honey, so this recipe is best for bakers with some sourdough experience. You’ll shape the loaf, then refrigerate it overnight before baking, so plan ahead.
If you’re new to sourdough, consider practicing with a straightforward loaf first to build confidence before trying this oat-enriched version.
The hydrated oats keep the crumb tender while adding flavor and texture. The finished loaf is excellent toasted with butter and honey but also pairs well with savory toppings. If you have extra starter to use, try a different recipe for variety.
Ingredients
The full recipe appears below. These notes highlight the ingredients that most affect the result.
- Oats – Use old-fashioned rolled oats, not quick oats or steel-cut oats. They are hydrated with hot water before being folded into the dough.
- Sourdough starter – Use an active 100% hydration starter near its peak when you mix the dough. A weak or overripe starter slows fermentation.
- Bread flour or higher-protein all-purpose flour – Aim for flour with roughly 11.5–12.5% protein. The dough is soft and sticky, so a stronger flour helps it hold shape. If you bake outside the U.S., choose flour by protein content rather than name.
- Whole wheat flour – A small amount adds depth and an earthy flavor. You can substitute more bread flour for an all-white loaf or use a small portion of rye for a different flavor profile.
- Honey – Honey adds mild sweetness and contributes to a tender crumb. Replace it with an equal weight of maple syrup if preferred.
- Additional rolled oats – These coat the outside of the shaped loaf. Apply before the loaf goes into the banneton so the oats adhere firmly.
Why hydrate the oats?
Hydrating the oats before adding them to the dough lets them absorb water so they stay tender in the baked loaf instead of drawing moisture from the crumb. Hydrated oats are also easier to incorporate with minimal mixing.
Be sure the oats are completely cool before folding them into the dough; warm oats can raise dough temperature and change fermentation timing.
How to make honey oat sourdough
Because of the hydrated oats and honey, this dough behaves a bit differently from a classic sourdough. Expect a softer, slightly stickier dough and adjust handling accordingly.
Have your starter at or near peak activity before you begin.
Hydrate the oats. Pour hot water over the rolled oats and let them soften. Cool completely before adding them to the dough.
Mix the dough. Combine the starter, room-temperature water, honey, and flours. Let the mixture rest briefly, then add salt and the reserved water gradually as needed. Mix until the dough develops enough strength to pass the windowpane test.
Add the oats and strengthen the dough. Mix in the cooled hydrated oats, then transfer the dough to a lightly greased bowl or container. After a short rest, perform two coil folds about 30 minutes apart. If the dough still feels very slack, give it one additional gentle fold.
Finish bulk fermentation. Continue fermenting until the dough has risen about 30–50%, looks puffy and aerated, and jiggles gently when the container is moved.
Shape and coat with oats. Pre-shape the dough and let it rest 15–20 minutes. Shape it into a tight round or batard. Lightly mist the exterior with water and roll it in additional oats. Place seam-side up in a lightly floured banneton. The oat coating is optional.
Cold proof. Cover and refrigerate for 12–16 hours.
Bake. Place a baking sheet on the rack beneath your Dutch oven or baking vessel to protect the bottom of the loaf. Preheat the oven and baking vessel thoroughly. Turn the cold dough onto parchment, score it with one long cut, and bake covered at 475°F (245°C). When the interior temperature approaches 195–200°F (90–93°C), remove the lid, reduce the oven to 425°F (220°C), and finish baking uncovered until the center reaches about 205–210°F (96–99°C) and the crust is deeply golden. Keeping the loaf covered for most of the bake protects the oat topping from over-browning; removing the lid at the end helps the crust color and the oats toast.
Allow the bread to cool completely on a wire rack before slicing. The crumb continues to set as it cools; cutting too soon can produce a gummy texture.
Example timeline
Fermentation time depends on starter strength, dough temperature, flour, and room temperature. Use the schedule below as a flexible framework: follow the dough’s visual and tactile cues rather than the clock.
Example schedule for a loaf ready to slice around mid-afternoon
| Time | What to do |
|---|---|
| Morning | Feed your starter so it will be active when you begin mixing. |
| Late morning | Hydrate the oats with hot water and allow them to cool. |
| Noon | Mix starter, most of the water, honey, and flours. Rest, then add salt and any reserved water as needed. Mix until the dough passes the windowpane test. |
| Early afternoon | Add cooled hydrated oats, transfer to a container, and perform gentle folds to bring the dough together. |
| Throughout afternoon | Perform 1–3 coil folds about 30 minutes apart as needed. Continue bulk fermentation until the dough has increased 30–50% and looks puffy with visible bubbles. |
| Late afternoon | Pre-shape, bench rest 15–20 minutes, then final shape and coat with oats. Place in banneton and refrigerate 12–16 hours. |
| Next morning | Preheat oven and baking vessel thoroughly, turn out the cold loaf, score, and bake covered, then finish uncovered until fully cooked and golden. |
Adjust the schedule to match your starter’s typical timing. The end of bulk fermentation is the most variable stage—shape the dough when it shows the right signs, not just because a set time has passed.
Tips for Success
- Cool the hydrated oats completely before adding them to the dough.
- Use the windowpane test to judge gluten development rather than relying on a fixed mixing time.
- Add reserved water gradually; you may not need all of it depending on your flour.
- Work with damp hands and a bench scraper to handle the sticky dough more easily.
- Watch the dough during bulk fermentation for a 30–50% rise, a puffy look, visible bubbles, and a gentle jiggle—these are better indicators than time alone.
- Apply oats before placing the loaf in the banneton for the most even, secure coating.
- Keep the loaf covered for most of the bake, then monitor the uncovered portion closely so the oats toast without burning.
Can I make this without a stand mixer?
Yes. A stand mixer makes development easier, but you can mix by hand. Combine the starter, water, honey, and flours, rest, then add salt. Use folding and gentle kneading with wet hands until the dough passes the windowpane test. Add the cooled hydrated oats and work them in gently. A bench scraper and damp hands will make handling sticky dough much simpler.
Can I extend the cold proof?
For learning the recipe, stick to 12–16 hours. A longer cold proof may work with a very slow starter and a cold refrigerator, but this dough has a soft structure and can become more difficult to shape after extended fermentation.
Storage
Cool the bread completely before storing. Keep it at room temperature in a bread bag, paper bag, or loosely wrapped in a clean towel. For best texture, eat within 2–3 days. Avoid refrigeration unless necessary, since the fridge speeds staling for sourdough.
Freezing
This bread freezes well. For everyday use, cool completely, slice, and freeze individual slices in a freezer-safe bag with parchment between slices if desired. Toast slices directly from frozen. For longer storage, wrap the whole loaf well and freeze; thaw at room temperature and refresh briefly in the oven before serving.

Honey Oat Sourdough
Ingredients
Hydrated Oats
- 60 grams (2/3 cup) old-fashioned rolled oats
- 80 grams (1/3 cup) water, approximately 170°F (77°C)
Dough
- 100 grams (1/2 cup) active sourdough starter
- 300 grams (1 1/4 cups) water, divided (approx. 68–75°F / 20–24°C)
- 30 grams (1 1/2 tbsp) honey
- 400 grams (3 1/3 cups) bread flour or higher-protein all-purpose flour
- 50 grams (1/3 cup + 1 tbsp) whole wheat flour
- 10 grams (1 3/4 tsp) kosher salt
- Additional flour for dusting and shaping as needed
- Additional rolled oats for coating, as needed
Instructions
- Combine the rolled oats and 80g hot water in a small bowl, stir to moisten, cover, and let sit at least 30 minutes until soft. Cool completely before using.
- Add the active sourdough starter, 280g of the room-temperature water, and honey to a mixing bowl. Mix briefly to combine.
- Add the bread flour and whole wheat flour. Mix on low until no dry flour remains and a rough dough forms. Cover and rest about 30 minutes.
- Add the salt and begin mixing on low. Gradually add some or all of the remaining 20g water as needed. Mix until the dough is smooth, elastic, and can pass the windowpane test.
- Monitor dough temperature; aim for a finished dough around 75–78°F (24–26°C). If the dough overheats, pause and let it cool before continuing.
- Once the dough passes the windowpane test, mix in the cooled hydrated oats on low speed for 1–2 minutes, just until evenly distributed.
- Transfer the dough to a lightly greased bowl. With damp hands, fold the dough over itself 2–3 times to form a cohesive ball. Cover and rest about 30 minutes.
- Perform a coil fold, then a second coil fold about 30 minutes later. If the dough still feels slack, perform one more gentle fold 30 minutes after that.
- Continue bulk fermentation until the dough has increased 30–50% in volume, appears puffy with bubbles, and jiggles gently when moved.
- Turn the dough onto a lightly floured surface. Pre-shape into a loose round or oval and rest 15–20 minutes.
- Final shape into a tight round or batard, creating surface tension without deflating the dough.
- Spread rolled oats on a plate. Lightly mist the shaped loaf with water and roll it in the oats so they adhere. Place seam-side up in a lightly floured banneton. Cover and refrigerate 12–16 hours.
- Preheat the oven to 475°F (245°C) with the Dutch oven or baking vessel inside and a sheet pan on the rack below to protect the loaf bottom. Preheat the vessel an additional 25–30 minutes once the oven reaches temperature.
- Turn the cold dough onto parchment, score with one confident cut, and place it into the preheated vessel. Cover and bake at 475°F (245°C) for about 25–30 minutes, checking the internal temperature toward the end.
- Reduce oven to 425°F (220°C), remove the lid, and bake uncovered 5–10 minutes until the crust is deeply golden and the center reaches 205–210°F (96–99°C).
- Remove the loaf to a wire rack and cool completely before slicing.
Notes
- Use a kitchen scale and weigh ingredients in grams for the most accurate and consistent results. Cup measures are approximate.
- Choose bread flour or a higher-protein all-purpose flour (about 11.5–12.5% protein) for best structure. Adjust flour choice by protein content if you bake outside the U.S.
- The recipe lists 300g total water; 20g is held back and added gradually as needed. You may not need all of it depending on your flour.
