Cut bread into ½-inch thick cubes. You can opt to remove the crusts if desired, I find they add a nice texture.
Place the diced bread onto a large rimmed baking sheet. Evenly drizzle the olive oil over the bread cubes and then sprinkle the seasonings over the cubed bread. Using your hands, toss to coat the cubes evenly in the seasonings and then spread out the bread onto the sheet pan being sure to not overcrowd the bread so everything browns evenly.
Let the bread cubes sit for 2 minutes to absorb the flavor and then place the sheet pan into the oven and bake for 10 minutes. Remove the pan and flip the croutons or give the pan a good shake. Return to the oven and bake for additional 5 minutes, or until croutons are browned.
Allow the croutons to cool to room temperature and then use immediately or store in an airtight container for up to 2 weeks.
Notes
Storage: Allow the croutons to cool fully and then store in an airtight container for up to 2 weeks in the pantry.Bread Options: You can use any bread you like to make croutons, but my personal favorite is Italian Bread or French Bread. Be sure to use Gluten-Free bread if you need gluten-free croutons. Cheesy Croutons: Add ¼ cup grated Parmesan cheese to the bread cubes before baking. Air Fryer Instructions: (Recipe needs cut in half)
If your model of an air fryer needs to be preheated, heat to 400 degrees.
In a large mixing bowl, toss 2 tablespoons of olive oil, ¼ teaspoon salt, ¼ teaspoon onion powder, ½ teaspoon garlic powder, ½ teaspoon oregano, and 1 teaspoon dried parsley with 4 cups of cubed bread.
Let the bread sit in the mixture for 2 minutes to absorb the flavor.
Spread the cubed bread in the basket of the air fryer and toast for 3 minutes at 400 degrees.
Remove the basket and shake and toast for an additional 3 minutes.
Check to be sure the bread is evenly toasted, if not, return to the air fryer for 2 minutes.
