A gratin [GRAH-tn] is any dish that’s covered with cheese or bread crumbs, then browned in the oven. This one features fresh tomato and mozzarella slices dressed with olive oil, balsamic vinegar, and fresh basil — the staples of Italy’s caprese [kah-PREH-seh] salad.
Although a caprese salad isn’t traditionally baked, the idea of turning it into a gratin really isn’t that far-fetched — just cross the border from Italy to the south of France, and baked tomatoes with a crumb topping are standard fare.

Test Kitchen Tip
White balsamic vinegar is similar to regular, it’s just a bit milder and won’t darken the gratin. Either type will do.
Instructions
Preheat oven to 400°.
For the crumb topping, pulse bread, 1 Tbsp. oil, zest, and garlic in a food processor to fine crumbs.
Brush a 1-qt. gratin dish with oil; sprinkle with ½ cup crumb topping.
For the gratin, slice tomatoes ½-inch thick; season with salt and pepper. Slice mozzarella 1/4-inch thick; halve slices. Alternate layers of tomato and mozzarella in prepared dish, covering cheese as much as possible with tomatoes to prevent too much melting. Drizzle oil over gratin, then sprinkle with remaining 1 cup crumb topping.
Bake gratin until cheese is bubbly and crumbs are golden, 20–25minutes.
Drizzle gratin with vinegar, then sprinkle basil over top.
