Cut bread into ½-inch thick cubes. You can remove the crusts if desired. I find they add a nice texture.
Place the cubed bread onto a large rimmed baking sheet. Drizzle with oil and sprinkle with salt, onion powder, garlic powder, oregano, and parsley. Using your hands, toss to coat the cubes evenly with the seasonings, then spread them out in a single layer on the sheet pan. Try not to overcrowd the pan so the croutons can brown evenly. Use two pans if you have to.
Let the bread cubes sit for 2 minutes to absorb the flavor, then 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 an additional 5 minutes, or until the croutons are browned.
Let the croutons cool to room temperature, then use immediately or store in an airtight container for up to 2 weeks.
Notes
Storage: Let the croutons cool completely, 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. Use Gluten-Free bread if needed.Cheesy Croutons: Add ¼ cup grated Parmesan cheese to the bread cubes before baking. Air Fryer Instructions: Season as directed and air-fry in batches at 400℉ for 6 minutes, shaking after 3 minutes.
