Preheat oven to 325°F and line a rimmed baking sheet with parchment paper. Cut the loaf of sourdough bread into ¾-inch cubes using a serrated knife.
16 ounces (about 10 cups cubed) sourdough bread
In a large bowl, toss the sourdough bread cubes with olive oil and seasonings. Arrange the seasoned bread pieces in a single layer on the prepared parchment-lined baking sheet.
¼ cup extra virgin olive oil, 1 teaspoon kosher salt, 1 teaspoon garlic powder, 1 teaspoon Italian seasoning, ½ teaspoon onion powder, ½ teaspoon black pepper
Bake the croutons for 20-25 minutes or until they are golden brown and crispy. Be sure to check them frequently to avoid burning.
Remove the baking sheet from the oven and allow the croutons to cool completely. They will continue to crisp up as they cool. Store the croutons in an airtight container at room temperature for up to one week.
Notes
Quick Tip: The best bread for making croutons is stale bread, which is easier to cut and will absorb the seasonings and oil better. If your sourdough bread is very fresh and soft, leave it out on the counter for a few hours or overnight to dry it out before making the croutons.
Storage: Store croutons in an airtight container for up to 1 week at room temperature or up to 6 weeks in the freezer.
To Refresh Stale Croutons: Place croutons on a rimmed baking sheet in a 400°F oven for 3-4 minutes before serving.
