Step 1

Preheat oven to 450°F. Line 2 sheet pans with parchment paper.

Step 2

Cut baguettes diagonally into 1/4-inch-thick slices. Place on the prepared sheet pans and lightly brush each side with olive oil. (If the bread doesn’t all fit, bake multiple batches.)

Step 3

Bake, turning toasts and switching pan positions halfway through cook time, until crostini are browned and crispy, 8-10 minutes total.

Step 4

Let toasts cool, then arrange them on a large serving board surrounded by the toppings. Let guests build their own crostini.
