Master the art of transforming leftover sourdough into crispy, seasoned croutons. With their tangy base flavor and satisfying crunch, these homemade croutons add gourmet flair to salads and soups while making delicious use of day-old bread.
Key Ingredients
- Sourdough Bread (1-2 days old): The perfect sturdy base for crispy croutons
- Extra Virgin Olive Oil: Ensures even browning and rich flavor
- Garlic Powder: Adds savory depth
- Dried Herbs: Provides aromatic seasoning
- Sea Salt: Enhances overall flavor
- Black Pepper: Adds subtle warmth
- Parmesan (optional): Creates delicious cheesy variation
- Parchment Paper: Ensures easy release and even baking
Preparation Steps
- Prepare the Bread:
- Cut bread into even 3/4-inch cubes, removing any tough crusts. Let fresh bread dry slightly if needed.
- Season:
- Mix oil and seasonings in a large bowl. Add bread cubes and toss until evenly coated. Let rest briefly.
- Bake:
- Arrange cubes with space between on lined baking sheet. Rotate pan halfway through baking. Monitor closely near end.
- Cool:
- Allow croutons to cool completely on the baking sheet for maximum crispness.

A professional tip: adding a small amount of nutritional yeast to the seasoning blend accentuates the natural umami flavors of sourdough.
Storage Instructions
Store in airtight glass containers with tight-fitting lids. Add a paper towel layer to absorb moisture. Keep at room temperature and monitor crispness. For extended storage, freeze seasoned unbaked cubes.
Flavor Variations
Experiment with different seasoning combinations: Mediterranean herbs with dried tomatoes, spicy versions with chili powder, classic ranch seasoning, aromatic curry powder, or elegant herbs de Provence.
Serving Ideas
These croutons shine in classic Caesar salads, hearty soups, or atop creamy bisques. Plain versions complement cheese boards, while seasoned varieties enhance any green salad or soup.

Presentation Tips
Add croutons just before serving. Place around soup edges to maintain crispness. Serve separately with salads. Portion appropriately when serving as snacks.
