How to Make High Protein Sourdough Bread
This high protein sourdough bread is so soft and light, you’d never guess it’s made with anything other than white flour—let alone that it has an extra boost of protein!
As a mom, one of my favorite things to do is sneak healthy ingredients into meals without any fuss or fights. Sourdough bread is a staple in our home, and since I know my son will always eat it, it’s the perfect target for my secret nutrition-boosting experiments!
Adding Flavours To Sourdough
Sourdough is incredibly versatile, allowing you to experiment with different flavors while maintaining a strong dough structure. The key is to balance hydration and mix-in ratios carefully.
- Wet Add-Ins (e.g., fruit purees, mashed vegetables, or honey): These can introduce extra moisture, so you will need to adapt the liquid accordingly. When I am adding wet ingredients such as tea or whey, I will simply swap out the water 1:1 for tea or whey.
- Dry Add-Ins (e.g., nuts, seeds, dried fruit, or cheese): These don’t contribute extra moisture, but they can affect gluten development if overused. It’s best to distribute them evenly and avoid overloading the dough, which can weaken its structure.
- General Guideline: For every 500g of flour, you can safely incorporate up to 100g of dry mix-ins without compromising the dough’s ability to rise and develop properly. If adding both wet and dry ingredients, adjust accordingly to maintain the correct dough consistency.
By carefully balancing ingredients, you can create delicious sourdough variations while ensuring a successful bake every time!
The Benefits Of Chickpeas in Sourdough Bread
Want to know the healthy, protein-rich ingredient I snuck into this recipe?
It’s chickpeas!
I got the idea from a pumpkin sourdough bread recipe that uses pumpkin purée as part of the liquid. Since pumpkin creates a soft, delicious loaf, I wondered what else might work the same way. That’s when it hit me—chickpea purée!
Why Chickpeas?
Chickpeas aren’t just a plant-based protein powerhouse; they also:
✔️ Enhance the texture – Creating an incredibly soft, airy crumb.
✔️ Add fiber – Making the loaf more filling and gut-friendly.
✔️ Boost protein content – Helping keep you fuller longer and supporting muscle health.
✔️ Improve hydration – Helping maintain moisture for a longer-lasting fresh loaf.
✔️ Have a neutral taste – You won’t even know they’re there—I pinky swear!
By adding chickpeas, you’re giving your sourdough an extra protein boost without relying on dairy or eggs. This simple swap transforms your loaf into a more satisfying and nutritious option.
Why Add Protein to Sourdough?
Protein is essential for satiety, muscle health, and balanced energy levels. Traditional sourdough relies on gluten for structure, but adding a plant-based protein source like chickpeas enhances the nutritional profile while maintaining a soft, airy crumb.
Best of all? You won’t taste the chickpeas! They disappear into the dough, leaving you with a loaf that’s tender, satisfying, and packed with nutrients.
This simple trick turns your homemade sourdough into a protein-boosted powerhouse—perfect for a healthy breakfast or post-workout snack.
High Protein Sourdough Bread Timeline
The process follows the usual sourdough schedule: feed the starter the night before, mix the dough the next morning, and bake the following day after an overnight cold ferment.
The Night Before:
Feed your starter. Feeding your sourdough starter before baking ensures it’s active, bubbly, and strong enough to leaven your bread. A well-fed starter has plenty of yeast and beneficial bacteria, which produce the gases needed for a good rise and the acids that develop flavor.
Ideally, you should feed your starter 4 to 12 hours before mixing your dough, depending on room temperature and starter strength. When it’s at its peak—doubled in size and full of bubbles—it’s ready to use. Baking with an underfed or sluggish starter can lead to dense, under-risen bread, so regular feedings keep your sourdough vibrant and reliable.
In the Morning:
Blend the starter, chickpeas, salt, and water until completely smooth. A blender or immersion stick is best to avoid any detectable chickpea skins.
Add the flour and mix well until evenly hydrated.
Let the dough rest for 30 minutes.
Letting sourdough rest before stretching—called the autolyse phase—allows the flour to fully absorb water, activating enzymes that begin gluten development. This short rest (typically 20-60 minutes) makes the dough more extensible and easier to handle, reducing the effort needed during stretching and folding.
Resting prior to stretching and folds also improves hydration, leading to a better crumb structure and enhanced flavor. Skipping this step can result in a tighter, less open crumb and dough that’s harder to work with. By allowing the gluten network to form naturally, you create a stronger, more elastic dough that will rise better and yield a beautifully textured loaf.
Stretch and Fold
Over the next 2 hours, do 4 stretch-and-folds every 30 minutes.
Stretching and folding strengthens the gluten network, helping the dough develop structure without intensive kneading. This process evenly distributes gases, creating an airy crumb while improving elasticity.
It also enhances fermentation, leading to better rise and flavor. Regular folds build a strong dough, ensuring a well-shaped, beautifully textured sourdough loaf.
Bulk Ferment
Cover and let the dough rise for 6–8 hours at room temperature.
Bulk fermentation is crucial for developing sourdough’s structure, flavor, and rise. During this stage, the wild yeast and bacteria in your starter break down starches, producing gases that create an airy crumb. It also strengthens gluten, making the dough easier to shape.
A proper bulk ferment (typically 4-6 hours at room temperature) ensures good texture and depth of flavor. Rushing this step can lead to dense bread, while over-fermenting can weaken the dough. By monitoring fermentation signs—like dough expansion and bubbles—you’ll achieve a well-risen, flavorful loaf with the perfect balance of chewiness and lightness.
Shape
- Turn the dough onto a lightly floured surface.
- With wet hands, stretch it gently and fold the corners into the center.
- Flip it over and shape into a tight round.
- Let it rest for 40 minutes, then repeat the shaping process.
Overnight Cold Ferment
Transfer the dough (seam side up) into a floured proving basket or bowl lined with a tea towel.
Refrigerate overnight.
Bake
- Preheat the oven (with a Dutch oven inside) to 250°C.
- Remove the dough from the fridge, and transfer onto parchment paper, score the top, and place it in the preheated Dutch oven.
- Bake for 45–50 minutes:
- Keep the lid on for 30–35 minutes.
- Remove the lid for the last 10–15 minutes to develop a golden crust.
Baking the Perfect Chickpea Sourdough
Leaving the lid on for the full 45 minutes results in a softer crust by trapping steam. For a crispier crust, remove the lid for the last 15 minutes of baking. Let the bread cool for a few hours for easier slicing, but if you can’t wait, enjoy it warm! Use an oven thermometer to ensure accurate baking temperatures, and place a baking stone or preheated Dutch oven in the oven for optimal heat retention and even baking.
