From the MyKitchenBank Kitchen

A rustic, naturally leavened bread that transforms sourdough starter discard into a tender, subtly spiced loaf studded with pinto beans for protein and texture. Pumpkin puree adds moisture and a warm autumn flavor, while the beans contribute an earthy character. Perfect for sandwiches, toast, or alongside soups—and a smart way to use discard instead of throwing it away.

Steps

Before you start

Remove sourdough discard from the fridge 30 minutes before mixing so it reaches room temperature
Drain and rinse canned pinto beans thoroughly
Preheat oven to 450°F (232°C) 30 minutes before baking
Line a Dutch oven or covered baking vessel with parchment paper

1
Mix dough
- In a large mixing bowl, combine 1 cup (240 ml) sourdough discard, 0.75 cup (180 ml) pumpkin puree, and 0.5 cup (120 ml) room-temperature water.
- Stir until mostly combined.
- Add 2.25 cups (300 g) bread flour, 0.5 cup (60 g) whole wheat flour, 1.5 teaspoons (9 g) salt, 1 teaspoon (2 g) nutmeg, 0.5 teaspoon (1.5 g) cinnamon, and 0.25 teaspoon (0.5 g) ginger if using.
- Mix with a bench scraper or wooden spoon until all flour is hydrated and a shaggy dough forms—about 2 minutes.

Ready when: All flour is incorporated and dough is roughly shaggy
Tip: Do not overwork the dough at this stage. A rough, uneven texture is fine.
2
Autolyse and rest
- Cover the bowl with a damp kitchen towel or plastic wrap.
- Let the dough rest at room temperature for 45 minutes.
- This resting period allows the flour to fully hydrate and makes the dough easier to work with.
+ Show details− Hide details
Tip: This rest is worth the time and helps develop gluten structure without additional kneading.
3
Fold in beans and develop gluten
- Add 0.75 cup (150 g) drained and patted-dry pinto beans to the dough.
- Perform 6–8 sets of stretch-and-folds over the next 30 minutes, at 5-minute intervals.
- Use a wet hand or bench scraper to stretch one side of the dough from the bowl's edge toward the center, fold it over itself, rotate the bowl 90 degrees, and repeat.
- By the end, the dough will feel firmer, smoother, and the beans will be evenly distributed throughout.
+ Show details− Hide details
Ready when: Dough is smooth, elastic, and beans are evenly mixed throughout
Tip: Stretch-and-folds add strength without heavy kneading, perfect for wet doughs. If a bean breaks, it's fine—spread it through the dough.
4
First rise (bulk fermentation)
- Cover the bowl and let it rise at room temperature (68–72°F / 20–22°C is ideal) for 4–5 hours.
- The dough should increase in volume by 50–75%, with some visible bubbles on the surface and sides.
- It should feel airy but still hold its shape.
+ Show details− Hide details
Ready when: Dough has increased 50–75% in volume with visible fermentation bubbles
Tip: Fermentation time varies with kitchen temperature. In a cooler kitchen (65°F / 18°C), it may take 5–6 hours. Poke the dough gently—if it slowly springs back halfway, it's ready for shaping.
5
Preshape and bench rest
- Turn the dough onto a lightly floured work surface.
- Use a bench scraper to gently preshape it into a round or oval (don't deflate it aggressively).
- Let it sit uncovered for 20 minutes to relax the gluten.
+ Show details− Hide details
Ready when: Dough is no longer tight and springs back gently when poked
Tip: A gentle hand here prevents degassing. You want the preshape to retain its shape without tight tension.
6
Final shape and proof
- Shape the dough into a round or oval loaf with a slight tension on the surface (pull the sides toward the center, then flip seam-side down).
- Place it seam-side up in a floured banneton or a bowl lined with a floured kitchen towel.
- Cover with plastic wrap or a plastic bag and let it rise at room temperature for 1–2 hours until puffy.
- Alternatively, refrigerate overnight (8–12 hours) for deeper flavor—if chilling overnight, do not let it come fully to room temperature before scoring.
+ Show details− Hide details
Ready when: Dough is puffy, and a gentle poke leaves a slight indentation that slowly springs back halfway
Tip: Overnight cold fermentation develops more complex flavor and makes scoring easier. If using the cold option, pull from the fridge 15 minutes before baking.
7
Preheat Dutch ovenOven 450°F / 230°C
- Position a rack in the lower-middle of the oven and preheat to 450°F (232°C) for at least 30 minutes.
- Place a Dutch oven or covered baking vessel (4–5 quart / 4–5 L) inside to preheat as well.
+ Show details− Hide details
Ready when: Dutch oven is hot and ready (carefully test with a drop of water on a wooden spoon—it should sizzle immediately)
Tip: A preheated Dutch oven creates steam, which gives the bread a crispy crust. Do not skip this step.
8
Score and bakeOven 450°F / 230°C
- Carefully remove the hot Dutch oven from the oven.
- Line the bottom with parchment paper if needed (it likely has some from prepping).
- Working quickly to minimize heat loss, invert the proofed dough onto the parchment, seam-side down.
- Using a sharp knife or lame (bread scoring blade), make a single confident slash about ¼ inch (0.6 cm) deep across the top at a 30–45 degree angle, or make an X with two intersecting slashes.
- Immediately replace the lid and return to the oven.
- Bake covered for 25 minutes to trap steam.
+ Show details− Hide details
Ready when: Steam has developed inside the Dutch oven (visible as condensation on the lid)
Tip: A confident, quick slash prevents the knife from catching and dragging the dough. If using a banneton, invert it directly onto the parchment in one smooth motion.
9
Finish bakingOven 420°F / 215°C
- Remove the Dutch oven lid and reduce the oven temperature to 420°F (216°C).
- Bake uncovered for 18–22 minutes longer until the crust is deep golden-brown and sounds hollow when tapped on the bottom.
- The loaf should reach an internal temperature of 205–210°F (96–99°C) at the center.
+ Show details− Hide details
Ready when: Crust is deep golden-brown, bottom sounds hollow when tapped, and internal temperature is 205–210°F (96–99°C)
Tip: If the crust is browning too fast, tent it loosely with foil. Use the internal thermometer to avoid underbaking, which results in a gummy crumb.
10
Cool completely
- Transfer the loaf to a wire cooling rack and let it cool completely at room temperature for at least 1–2 hours before slicing.
- The crumb will set and the flavor will mellow as it cools.
+ Show details− Hide details
Ready when: Loaf is at room temperature and feels light when picked up
Tip: Slicing warm bread can compress the crumb. Patience here rewards you with clean slices and better texture.

Tips

Sourdough discard does not need to be freshly fed or particularly active. Unfed, refrigerated discard works beautifully in this recipe and creates a slower, more forgiving fermentation.
This dough is wetter than a typical sourdough loaf due to the pumpkin and beans, so use a bench scraper and wet hands during shaping. Avoid adding extra flour unless absolutely necessary.
The pinto beans should be soft enough to break easily with a spoon but not mushy. If canned beans are very soft, pat them extra dry before adding to prevent excess moisture.
For a rustic, open crumb, extend the bulk fermentation slightly (to 5–6 hours) and ensure proper stretch-and-fold technique. For a tighter, more standard crumb, ferment for 4 hours and be gentle with the dough.

Make ahead

Store the shaped dough in the refrigerator overnight (8–12 hours) after Step 6 for deeper flavor development and easier scoring. Bake directly from the cold dough without thawing.

Storage & reheating

Room temperature (1–2 days): Wrap the cooled loaf in a clean kitchen towel or place in a paper bag. Refrigerator (up to 5 days): Wrap tightly in plastic wrap or an airtight container. Revive by misting lightly with water and warming in a 375°F (190°C) oven for 8–10 minutes. Freezer (up to 3 months): Wrap in plastic wrap and foil, then place in a freezer bag. Thaw at room temperature for 4–6 hours, then refresh in the oven as above if desired.

Substitutions

bread flour or all-purpose flour → All-purpose flour. Use all-purpose flour in place of bread flour for a slightly softer, less chewy crumb. The loaf will be equally delicious.
cooked pinto beans → Cooked black beans, chickpeas, or kidney beans. Any cooked bean with a firm texture works. Avoid overly soft beans, which may break apart during folding.
pumpkin puree (canned or homemade) → Butternut squash puree or sweet potato puree. Substitute in equal volume. Squash imparts a slightly earthier flavor; sweet potato adds more sweetness. Both work beautifully.
whole wheat flour → Rye flour or spelt flour. Use an equal weight of rye or spelt for a nuttier, more complex flavor. Rye absorbs slightly more water, so monitor dough consistency during mixing.
