Heat the oil over medium high heat in a skillet large enough to easily toss your croutons during cooking.

Stir the bread cubes in the oil to ensure every bread surface is well coated with oil. Continue to stir while the bread cubes brown.

Make sure they’re adequately browned, but don’t burn them. I recommend never turning your back on the suckers as they cook. Continue to stir until done then remove from heat.
