3/8-inch-thick slices French baguette

Olive oil for brushing

Preheat the oven to 400°F. Lightly brush oil on both sides of each bread slice. Arrange them in a single layer on a baking sheet. Bake for about 2 minutes on each side, or until golden brown but not firm all the way through. Serve at room temperature.

Advance preparation

The crostini will keep for up to 3 days in an airtight container at room temperature.
