Transform day-old sourdough bread into golden, crispy croutons that capture the bread's natural tang while adding delightful crunch. These homemade gems elevate any salad or soup while making excellent use of leftover bread.
Essential Components
- Day-Old Sourdough Bread: Provides a firm texture and developed flavor, perfect for crisping.
- Premium Extra Virgin Olive Oil: Ensures proper crisping while adding a rich, well-rounded taste.
- Fresh Garlic Powder: Free from anti-caking agents for a pure, bold garlic flavor.
- Pure Dried Herbs: Used without stems or excess powder for the best texture and aroma.
- Coarse Sea Salt: Enhances flavor with the right amount of seasoning.
- Fresh Ground Black Pepper: Adds balance and a subtle heat to complement the seasoning.
- Optional Grated Parmesan: Provides a savory, cheesy variation for added depth.
- Parchment Paper: Prevents sticking and ensures even baking for the best results.
Culinary Choreography
- Bread Preparation:
- Cut bread into consistent 3/4-inch cubes, removing extremely hard crusts. Slightly stale bread works best. If using fresh bread, allow cubes to dry slightly at room temperature.
- Seasoning Development:
- Combine olive oil with seasonings in large bowl, whisking to distribute evenly. Add bread cubes gradually, tossing thoroughly to ensure even coating. Let stand briefly to absorb flavors.
- Baking Process:
- Arrange seasoned cubes in single layer with space between each piece. Rotate pan halfway through baking. Watch carefully in final minutes to prevent burning.
- Cooling Stage:
- Allow croutons to cool completely on baking sheet. Proper cooling ensures maximum crispness and prevents condensation during storage.

My chef mentor taught me to add a tiny pinch of nutritional yeast to the seasoning mix it enhances the sourdough's natural umami beautifully.
Storage Solutions
Store cooled croutons in completely airtight container at room temperature. Consider using glass containers with tight-fitting lids rather than plastic bags for better protection. Place a paper towel in bottom of container to absorb any residual moisture. Check periodically for proper crispness. For longer storage, freeze uncooked seasoned bread cubes and bake as needed.
Creative Variations
Transform these croutons while maintaining their sourdough foundation. Create Mediterranean version with oregano, basil, and dried tomatoes. Develop spicy variation using chili powder and cayenne. Some chefs add ranch seasoning powder for classic flavor, while others incorporate curry powder for international flair. Consider herb de Provence blend for French inspiration.
Perfect Pairings
Enhance salads with these crispy additions by considering complementary flavors. Use classic garlic herb croutons for Caesar salads. Add spiced versions to hearty soups like minestrone or French onion. Top creamy bisques with cheese-enhanced croutons. Consider serving plain versions alongside cheese boards or as garnish for elegant pureed soups.

Serving Suggestions
Add croutons to dishes just before serving to maintain maximum crunch. For soups, place them around the edge rather than in center to prevent immediate sogging. Consider offering them separately at the table for salads, allowing guests to maintain preferred texture. When using as snacks, serve in small bowls with appropriate portions to prevent staleness from exposure.
These sourdough croutons represent the perfect way to elevate simple dishes while reducing food waste. The combination of proper seasoning and careful baking creates versatile additions to countless dishes. Whether topping a simple salad or garnishing an elegant soup, these crunchy bites consistently deliver satisfying texture and flavor.
