Why You’ll Love This Recipe

• Protein-packed without compromising taste — This bread delivers the tangy sourdough flavor you love while providing meaningful protein content to support your active lifestyle.

• Sandwich-friendly shape — Unlike round sourdough boules, this loaf is designed for perfect sandwich slices that actually fit your fillings .

• Reliable results every time — The addition of commercial yeast alongside sourdough discard ensures consistent rising, even for beginner bakers .

• Customizable to your preferences — Easily adapt with add-ins like jalapeños and cheddar for variety while maintaining the nutritional profile .

• Stays fresh longer than traditional sourdough — The enriched protein structure helps maintain moisture, keeping this bread tender for days.

Common Mistakes to Avoid

• Overproofing the dough — Because sourdough ferments more slowly than commercial yeast breads, it’s easy to let it rise too long. Watch for the dough to just double in size rather than over-expanding.

• Using inactive sourdough discard — If your discard lacks fermentation activity, the bread may lack flavor development. Ensure your discard has been recently fed or use it within a few days of refrigeration.

• Slicing while warm — Cutting into the loaf before it fully cools results in gummy, misshapen slices. Allow at least 1-2 hours of cooling time for clean cuts.

• Skipping the steam during baking — Steam creates that signature golden, glossy crust. Without it, the crust becomes dull and overly hard.

Required Equipment

• Loaf pan (9×5-inch) — Provides the classic sandwich shape and ensures even baking throughout the loaf .

• Kitchen scale — Ensures precise flour measurements for consistent results and accurate nutrition.

• Bench scraper — Helps handle sticky dough and keeps your work surface clean.

• Instant-read thermometer — Guarantees the bread reaches the proper internal temperature (190-200°F) for a fully baked interior.

Storage Instructions

Refrigerator: Store in an airtight container or bread bag for up to 5-7 days. For best results, slice only what you need to maintain freshness.

Freezer: Wrap tightly in plastic wrap and foil, or use a freezer-safe bag for up to 3 months. Thaw at room temperature and refresh in the oven or toaster.

Tip: This high-protein bread benefits from toasting after refrigeration, which restores its crusty exterior and enhances the flavor .

Recipe Details

📝 Ingredients

• 1 cup (240g) sourdough discard (room temperature)

• 2 cups (240g) high-protein bread flour (or a blend of bread flour and whole wheat)

• ½ cup (60g) vital wheat gluten — boosts protein content and improves texture

• 1 cup (240ml) warm water (110°F)

• 1 packet (2¼ tsp) active dry yeast

• 2 tbsp olive oil

• 1½ tsp salt

• 1 tbsp honey or maple syrup — optional, for slight sweetness

Directions

1. Activate the yeast (5 minutes): In a small bowl, combine warm water and yeast. Let sit until frothy (about 5-10 minutes).

2. Mix the dough (5 minutes): In a large mixing bowl, combine sourdough discard, bread flour, vital wheat gluten, and salt. Add the yeast mixture and olive oil, mixing until a shaggy dough forms.

3. Knead the dough (8-10 minutes): Knead on a lightly floured surface until smooth and elastic. The dough should be slightly sticky but hold together.

4. First rise (2-3 hours): Place dough in a lightly oiled bowl, cover, and let rise in a warm place until doubled in size.

5. Shape and second rise (2-3 hours): Punch down the dough, shape it into a loaf, and place in a greased 9×5-inch loaf pan. Cover and let rise again until puffy.

6. Bake (40-45 minutes at 375°F): Bake until golden brown and the internal temperature reaches 190-200°F. The bread should sound hollow when tapped.

7. Cool completely: Remove from pan and let cool on a wire rack for at least 1 hour before slicing.
