Preheat oven to 350 degrees F and line a rimmed baking sheet with parchment paper

Add olive oil to a large bowl and mix the seasonings in

Toss sourdough squares in the oil until everything is well coated

Distribute croutons evenly across the baking sheet

Bake 10-15 minutes or until the bottoms are golden and crispy

Flip the croutons and bake for another 10-15 minutes to brown the other side

You will know the croutons are done baking when they are completely dried out and crunchy, but not too dark
