Preheat the oven to 400°F. Line a baking sheet with parchment paper.
Arrange the bread slices on the baking sheet and brush them with half of the olive oil, then sprinkle them with 1/8 teaspoon of the salt and 1/8 teaspoon of the black pepper. Turn the slices over, brush with the remaining oil, and sprinkle with the remaining 1/8 teaspoon each salt and pepper.
Bake for about 6 minutes, then turn the baking sheet around in the oven to ensure even browning. Bake until the croutons are lightly browned, about 6 minutes. Remove from the oven and let cool completely before serving.
Yield: about 32 croutons
