Crostini are perfect spooned high with your pick of toppings.
Preheat oven to 350 degrees. Arrange baguette slices on two large rimmed baking sheets; brush both sides with oil, and season with salt and pepper.
Bake, rotating sheets halfway through, until golden, 15 to 20 minutes (if undersides are not browning, turn crostini over once during baking). Let cool on baking sheets. Top crostini with desired toppings, and serve.
To plan ahead for a party, bake the crostini toasts up to a week in advance, and top just before serving. To store, keep at room temperature in a resealable plastic bag, up to 1 week.
For an extra layer of flavor, use a garlic- or herb-infused oil.
