This Mexican-Inspired Sourdough Bread is the perfect accompaniment to your Fiesta night. Deliciously infused with cumin and tenderized with black beans, this loaf has amazing flavor and texture. Not a bad way to get extra protein!

Can You Put Beans in Sourdough Bread?

Yes, you can!

Have you noticed how much the health world is buzzing about protein? It’s protein this and protein that. In the last decade, supermarket shelves have adapted to the growing demand, offering protein-packed cookies, bars, chips—even bone broth is marketed for its protein benefits!

Now, I do not disapprove of this trend. In fact, I am all for it! But when you’re trying to eat healthy on a budget, you have to get creative. That’s why I developed this sourdough recipe, incorporating beans for an extra protein boost.

Why Add Beans to Sourdough?

• Increases the protein in your bread.
• Great way to get kids to eat nutritious beans without a fuss.
• Beans create an incredibly soft and springy texture.
• No detectable “beany” flavor—it’s pure magic!

How to Add Beans to Any Sourdough Bread Recipe

Adding beans to sourdough is easy.

The beans are blended with the liquid components of the bread (starter and water), ensuring they integrate seamlessly into the dough. When blended smooth, you won’t detect any fragments of bean.

Basic Formula for Adding Beans:

• Substitute a portion of the water for the beans.
• One can of drained beans (about 200g) is perfect for one loaf.
• Reduce the liquid weight to about 280g to balance the hydration.
• Any bean variety works: white beans, chickpeas, kidney beans, or black beans (like in this recipe).

This method is a game-changer for adding nutrients to your bread without altering its taste!

What Makes This Sourdough Bread Mexican?

To give this bread its Mexican flair, I use:

• Black beans – This special boost of protein gives the loaf a lovely deep brown color and additional moisture.
• Cumin – A warm, earthy spice that complements the sourdough beautifully. Cumin is the flavour of mexico!

Because cumin has a completely savory profile, this bread pairs best with savory toppings—think eggs, toasted sandwiches, or alongside soups and stews.

Ingredient Breakdown

Key Ingredients & Their Role

• Sourdough Starter – Provides natural fermentation, depth of flavor, and structure.
• Black Beans – Softens the texture, increases protein, and adds moisture.
• Cumin – Enhances the bread with a warm, earthy aroma.
• Flour – Bread flour or a mix of bread and whole wheat flour for added texture.
• Water – Essential for hydration and fermentation.
• Salt – Enhances flavor and strengthens gluten structure. Bread without salt is unbearable!

Optional Additions: Want to experiment? Try adding a pinch of smoked paprika or a handful of roasted corn kernels for extra flavor!

How to Make Mexican Sourdough Bread

The Night Before:

Feed your starter using equal quantities of flour and water. Use any discard for cookies, bagels, pancakes, or even a sourdough discard carrot cake.

In the Morning:

1. Blend starter, water, beans, salt, and cumin until completely smooth.
2. Mix in the flour until the dough is evenly hydrated.
3. Rest for 30 minutes.

Stretch and Fold:

Perform 4 stretch-and-folds every 30 minutes over the next 2 hours. Stretching and folding the dough strengthens gluten, improving structure and elasticity, which helps trap gas bubbles for an airy crumb. It also evenly distributes ingredients, enhancing fermentation by exposing more surface area to wild yeast.

This gentle method prevents overworking the dough while developing a balanced texture. For high-hydration doughs, like sourdough, regular stretching and folding build strength without needing aggressive kneading, leading to better oven spring and a beautifully open crumb.

Bulk Fermentation:

Let the dough rise for 6-8 hours at room temperature. Avoid over-proofing—if it’s warm, stick to the shorter end of the time range.

Shaping:

1. Tip the dough onto a floured surface.
2. Stretch and fold each corner into the center.
3. Flip over and shape into a taut round.
4. Rest for 30-40 minutes (less in warmer weather), then repeat shaping.

Overnight Cold Ferment:

Place the dough in a lined proofing basket (seam side up) and refrigerate overnight for up to 24 hours.

Baking:

1. Preheat a Dutch oven to 250°C (482°F) for at least 45 minutes.
2. Transfer the dough onto parchment paper, score the top, and place it in the hot Dutch oven.
3. Bake covered for 45-50 minutes, removing the lid in the last 10 minutes for a deeper crust color.

Storage & Serving Suggestions

How to Store Mexican Sourdough Bread:

• Keep at room temperature for 2-3 days in a paper bag or bread box.
• For longer storage, wrap in foil and refrigerate for up to a week.
• Freeze slices in an airtight container for up to 3 months.

Serving Ideas:

• Toasted with avocado and lime.
• Used as a base for chorizo and egg breakfast sandwiches.
• Paired with black bean soup or tortilla soup.

Troubleshooting Common Sourdough Issues

Dough is Too Wet

• Reduce hydration slightly if your kitchen is humid.
• Add 1-2 tablespoons of extra flour during mixing.

Dough Didn’t Rise Well

• Ensure your starter is active and bubbly before using.
• Let the dough ferment longer in cooler temperatures.

Dense or Gummy Bread

• Avoid over-proofing during bulk fermentation.
• Bake long enough and allow the loaf to cool completely before slicing.

Bread is Too Sour

• Reduce fermentation time if your dough is fermenting too long.
• Use a younger, less acidic starter for a milder flavor.

Hard Crust

• Store in a paper bag or wrapped in a clean cloth to retain moisture.
• If reheating, sprinkle with water and warm in the oven for 10 minutes.

Mexican Inspired Sourdough Bread Baking Tips:

• Preheat the Dutch Oven thoroughly – I recommend an hour at the highest temperature before lowering it when baking.
• Cold ferment overnight – Enhances flavor and texture.
• Allow the bread to cool fully before slicing – This prevents the inside from becoming gummy and ensures a better crumb structure.
• Experiment with flavors – Try adding roasted jalapeños or sun-dried tomatoes for a fun twist.
• Use freshly ground cumin – The flavor is much more vibrant than pre-ground cumin.

This Mexican-Inspired Sourdough is flavorful, nutritious, and an excellent way to sneak extra protein into your diet. Try it for your next Fiesta night and enjoy a warm, cumin-scented loaf that pairs beautifully with all your favorite Mexican dishes!

Happy baking!
