Sourdough Croutons

Sourdough croutons are golden, crunchy bites bursting with the rich, tangy flavor unique to sourdough. For a lighter, airier texture, use Soft Sourdough Bread; for a heartier crunch, go with Sourdough Baguettes. These easy croutons bring an irresistible crispy texture to salads, soups, or even as a savory snack on their own.

Ingredients

  • 2 pound Soft Sourdough Bread *see Note #1 below
  • 2/3 cup extra virgin olive oil
  • 3/4 teaspoon onion powder #see Note #2 below
  • 3/4 teaspoon garlic powder
  • 3/4 teaspoon salt

Instructions

  • Preheat oven to 375℉.
  • Cut the bread into slices, then into bite-sized cubes, ensuring they are roughly the same size for even baking.
  • In a large bowl combine oil and seasonings. Whisk until well combined.
  • Add the bread cubes to the oil mixture and toss thoroughly to coat each piece evenly.
  • Line two large, rimmed baking sheets with parchment paper. Divide the bread cubes between the trays, spreading them in a single layer. (Parchment paper helps to prevent the croutons from sticking and makes for easier clean up.)
  • Bake for 15-20 minutes, or until golden brown and crispy, stirring halfway through for even baking.
  • Cool completely on the baking sheet before using or storing. Store in an airtight container for up to one week.

Notes

Note #1- For half batch, here are the adjusted proportions:
  • 1 pound Soft Sourdough Bread 
  • 1/3 cup extra virgin olive oil
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt
Also, if using freshly baked Soft Sourdough Bread, slice it evenly and freeze the slices on a baking sheet for 15-20 minutes to firm them up. This helps ensure clean, even cuts without tearing. Once slightly firm, cube the bread for even baking.
Note #2- Additional Spice Add Ins
  • 1 teaspoon dried thyme- Wonderful on chicken salads, Caesar salads or hearty bean salads.
  • 1 teaspoon dried rosemary- Great for Mediterranean salads or salads during the holidays.
  • 1/2-1 teaspoon smoked paprika- Perfect for Southwest-style salads with corn, black beans, avocado and a lime-based dressing. 
  • 1/2 teaspoon black pepper- Adds a nice peppery kick to simple green salads. 
  • 1/4 teaspoon cayenne pepper- Ideal for spicy chicken salads or Mexican-inspired salads that feature grilled proteins, avocado, and cilantro. The heat adds an exciting contrast to creamy or fresh ingredients.
  • 2 teaspoons dried parsley- Works well with light, refreshing salads like a Greek salad or garden salad, as parsley brings a subtle, clean herbaceousness that complements lighter dressings.
  • 1 teaspoon Italian seasoning- Pairs wonderfully with antipasto salads or pasta salads, particularly those that include cured meats, cheeses, and a vinaigrette dressing, reinforcing the Italian flavors.
  • 2 tablespoons parmesan cheese (ideally freshly grated Parmigiano Reggiano)- Perfect for a variety of salads, adding a savory depth that enhances both creamy and tangy flavors.
