Preheat oven to 325 degrees.
Cut bread crosswise into 1/4-inch-thick round or oval slices. Spread on a large baking sheet and brush top of each slice with oil. Season lightly with salt and pepper and bake until golden brown and thoroughly crisp, 15 to 20 minutes. Remove from oven and let cool completely before serving.
Cook's Note: Croustades may be made up to several days in advance and stored in an airtight container once completely cool.
