Ingredients
6
medium plum tomatoes (1 lb), halved lengthwise
2
tbsp extra-virgin olive oil plus additional for brushing
7
garlic cloves, unpeeled
12
1/2-inch-thick slices baguette or Italian bread (about 2 1/2 inches wide)
1
to 2 tbsp finely sliced fresh mint
4
Kalamata or other brine-cured black olives, pitted and chopped
Directions
1.
Preheat oven to 350°F.
2.
Arrange tomatoes, cut sides up, in a shallow baking dish just large enough to hold them in 1 layer. Drizzle with 2 tablespoons oil and season with salt and pepper. Scatter garlic around tomatoes, then roast in middle of oven until tomatoes are tender and skins are wrinkled, about 1 hour. Cool, then transfer tomatoes to a plate, reserving garlic and oil in baking dish.
3.
While tomatoes are cooling, put bread slices on a baking sheet and brush lightly on both sides with additional oil. Bake in middle of oven until golden, 15 to 18 minutes.
4.
Peel roasted garlic cloves and mash to a paste with oil and juices from baking dish. Spread paste on toasts, then top each toast with a tomato half, cut side up.
5.
Serve crostini topped with mint and olives.
7.
Tomatoes and garlic paste can be prepared 1 day ahead and chilled, covered. Bring to room temperature before proceeding.
8.
Toasts can be baked 1 day ahead and kept in an airtight container at room temperature.
9.
Heat assembled crostini in a 350°F oven before serving if components are made ahead.
