Steps

Before you start

Bring sourdough discard to room temperature before mixing (30 min if cold).
Measure all dry ingredients and mix them together first.
Preheat oven to 450°F (230°C) for 30 minutes before baking.
Have a Dutch oven or covered bread pan ready in the oven.

1
Mix dry ingredients
- In a large mixing bowl, whisk together the whole wheat flour, sprouted grain flour, bread flour, and fine sea salt until evenly combined.
- This prevents the salt from clumping and ensures even distribution throughout the dough.

Ready when: Dry ingredients are evenly mixed with no streaks of flour.
Tip: Sift or whisk the whole wheat flour to break up any clumps before mixing.
2
Combine wet ingredients
- In a separate bowl, stir together the sourdough discard and warm water (85–90°F / 29–32°C) until the discard breaks down and the mixture is mostly smooth.
- Add the honey if using.
- The water temperature activates the yeast without killing it.
+ Show details− Hide details
Ready when: Mixture is uniform and liquid, with no large clumps of discard.
Tip: Do not use water hotter than 90°F (32°C) or you may damage the starter's wild yeast.
3
Combine and knead
- Pour the wet ingredients into the dry ingredients and mix with a bench scraper or wooden spoon until no dry flour remains.
- This will be a shaggy dough.
- Knead by hand in the bowl for 3–4 minutes, folding and pressing, until the dough comes together and the flour is hydrated.
- Do not overwork at this stage.
+ Show details− Hide details
Ready when: Dough is shaggy but holds together; no visible dry flour.
Tip: Wet doughs with whole grain flours hydrate slowly—allow the dough to rest 10 minutes before adding seeds if it feels too dry.
4
Add seeds and rest
- Sprinkle the pumpkin seeds, sunflower seeds (if using), and ground flaxseed over the dough.
- Fold and knead for 2–3 minutes until seeds are distributed throughout.
- Cover the bowl with a damp towel or plastic wrap and let rest for 10 minutes to allow flours to fully hydrate.
+ Show details− Hide details
Ready when: Seeds are evenly mixed into the dough; dough feels cohesive.
Tip: If dough is still very sticky, knead a minute longer but do not add dry flour—whole grain doughs need time to absorb moisture.
5
First rise (bulk fermentation)
- Leave the dough in the covered bowl at room temperature (68–72°F / 20–22°C) for 4–5 hours.
- If your kitchen is warmer (75°F / 24°C or above), reduce to 3–4 hours.
- The dough should increase by roughly 50% in volume; it will not double due to the density of whole grains.
- You can perform a poke test: gently press your finger 1 inch into the dough; it should spring back slowly and leave a small indentation.
+ Show details− Hide details
Ready when: Dough has risen 50%; poke test shows slow spring-back with slight indentation.
Tip: Whole grain doughs rise more slowly than white bread doughs, so do not be surprised by longer fermentation times.
6
Shape the loaf
- Turn the dough out onto a lightly floured work surface.
- With floured hands, gently shape into a round or oblong boule.
- If shaping for a loaf pan, flatten gently, fold the dough in thirds (lengthwise), seal the seam with the heel of your hand, and roll into a tight cylinder.
- Transfer to a 9×5-inch (23×13 cm) loaf pan, or place seam-side up in a banneton basket if baking free-form in the Dutch oven.
+ Show details− Hide details
Ready when: Dough is shaped with a seam at the bottom (loaf pan) or top (banneton).
Tip: Handle the dough gently to preserve the air bubbles; do not punch down aggressively.
7
Second rise (final proofing)
- Cover the pan or banneton with a damp towel.
- Let proof at room temperature for 2–3 hours, until the dough rises about 1 inch above the rim of the loaf pan (or fills the banneton about three-quarters full).
- Perform a poke test: press your finger gently; the dough should spring back very slowly or not at all, indicating it is ready.
- Alternatively, chill overnight (8–12 hours) in the refrigerator for enhanced flavor and easier scoring.
+ Show details− Hide details
Ready when: Dough rises 1 inch above pan; poke test shows minimal or no spring-back.
Tip: Cold overnight proofing develops deeper sourdough flavor and allows you to bake fresh bread in the morning.

Preheat oven and scoreOven 450°F / 230°C
- Position an oven rack in the lower third.
- Preheat the oven to 450°F (230°C) with a covered Dutch oven inside for at least 30 minutes.
- If proofing in the refrigerator, remove the dough 20 minutes before baking to take the chill off.
- If using a banneton, carefully turn the dough onto parchment paper.
- Score the top with a sharp knife or lame in a crosshatch or single long slash, about ½ inch deep.
- This controls expansion and creates a better oven spring.
+ Show details− Hide details
Ready when: Dutch oven is hot; dough is scored with visible cuts.
Tip: A hot Dutch oven traps steam, which creates a crispy crust and better oven spring.
9
Bake coveredOven 450°F / 230°C
- Carefully transfer the loaf (in the loaf pan or on parchment) into the preheated Dutch oven.
- Cover with the lid.
- Bake at 450°F (230°C) for 25 minutes.
- The covered environment steams the dough, promoting crust formation and rise.
+ Show details− Hide details
Ready when: Dough has risen and the top begins to brown slightly.
Tip: Do not open the oven during this time; steam loss will compromise the crust.
10
Finish bakingOven 400°F / 205°C
- Remove the lid from the Dutch oven.
- Lower the oven temperature to 400°F (200°C).
- Bake uncovered for 12–18 minutes, until the crust is deep golden brown and the loaf sounds hollow when tapped on the bottom.
- An instant-read thermometer inserted into the center should read 205–210°F (96–99°C).
+ Show details− Hide details
Ready when: Crust is deep golden brown; hollow sound when tapped; internal temperature 205–210°F (96–99°C).
Tip: Whole grain loaves bake slightly slower than white bread; the internal temperature is the most reliable doneness indicator.
11
Cool completely
- Transfer the loaf to a wire cooling rack.
- Allow it to cool for at least 1 hour before slicing.
- The crumb continues to set as it cools.
- Resist slicing warm bread, as the interior is still setting and may have a gummy texture.
+ Show details− Hide details
Ready when: Loaf is cool to the touch and feels firm.
Tip: Store the completely cooled loaf in an airtight container or breadbox to preserve moisture and texture.

Tips

Sourdough discard is typically thinner than an active starter and does not need to be at its peak; any unfed, room-temperature discard works perfectly.
Whole grain flours absorb water more slowly than white flour; the dough may feel quite wet initially. Trust the process and allow it to hydrate over 10–15 minutes.
If your kitchen is cool (below 65°F / 18°C), place the dough in a slightly warm spot—such as inside an oven with the light on—to speed fermentation.
Overnight cold proofing in the refrigerator not only develops superior sourdough flavor but also makes scoring easier and the loaf easier to handle.

Make ahead

You can prepare the dough through the first rise (step 5) up to 8 hours ahead, then refrigerate. Shape and proof in the fridge overnight (8–12 hours) for even better flavor development, then bake directly from cold.

Storage & reheating

Room temperature (bread box or paper bag): 2–3 days. Refrigerator (in an airtight container): up to 5 days; reheat slices in a 350°F / 175°C oven for 5 minutes to restore crispness. Freezer (in a freezer bag, sliced or whole): up to 3 months. Thaw at room temperature or toast directly from frozen.

Substitutions

sprouted grain flour (or sprouted spelt flour) → Spelt flour or emmer flour. These whole grains offer similar nutrition and nutty flavor; may require slightly more water due to lower hydration capacity.
raw pumpkin seeds (pepitas) → Sesame seeds, hemp seeds, or additional sunflower seeds. Any combination of nuts or seeds totaling 0.75 cup (100 g) works; adjust for personal preference and seed sizes.
bread flour → All-purpose flour. The loaf will have a slightly lighter, less chewy crumb; increase water by 1–2 tablespoons if the dough feels stiff.
whole wheat flour → Whole rye flour or farro flour. Rye and farro add earthy depth; use the same weight. Both absorb water slightly differently, so adjust liquid as needed.
