Preheat the oven to 350℉/175℃. This is an important step, so don’t skip it! A properly heated oven ensures that the croutons bake evenly and become wonderfully crispy.
Cut the bread into ½-inch thick cubes. Feel free to remove the crusts if you prefer, but I find they add a nice texture to the croutons.
Place the 8 cups of cubed bread onto a large rimmed baking sheet. Make sure to spread them out evenly, as overcrowding can lead to uneven browning.
Drizzle ¼ cup of extra virgin olive oil over the bread cubes. Make sure each piece is well-coated. This will help them toast beautifully.
Sprinkle with ½ teaspoon of kosher salt, ½ teaspoon of onion powder, 1 teaspoon of garlic powder, 1 teaspoon of dried oregano, and 2 teaspoons of dried parsley. Use your hands to toss everything together until the bread is completely coated in the seasonings.
Spread the seasoned bread cubes out on the baking sheet, ensuring they’re not too crowded. This is key for getting that perfect crunch!
Let the bread cubes sit for 2 minutes. This allows them to absorb the flavors of the oil and spices.
Place the sheet pan into the oven and bake for 10 minutes. The smell will be amazing at this point!
Remove the pan and flip the croutons or give the pan a good shake. This helps ensure that all sides get nicely browned.
Return to the oven and bake for an additional 5 minutes, or until the croutons are golden brown and crispy.
Allow the croutons to cool to room temperature. Once cool, you can enjoy them immediately or store in an airtight container for up to 2 weeks.
