Ingredients

• 6 medium heirloom tomatoes
• 3 tablespoons extra-virgin olive oil
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 2 large garlic cloves
• 2 teaspoons fresh thyme leaves
• 2 tablespoons fresh basil leaves
• 1 cup breadcrumbs
• 0.5 cup Parmesan cheese
• 2 tablespoons unsalted butter

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Thinly slice the heirloom tomatoes into approximately 1/4-inch thick rounds, discarding the stem ends.

Step 3

Grease the bottom of a 9-inch baking dish with 1 tablespoon of olive oil.

Step 4

Arrange the tomato slices in the dish, slightly overlapping, to create an even layer.

Step 5

Sprinkle the tomatoes with salt, black pepper, minced garlic, and fresh thyme leaves.

Step 6

Chop the fresh basil leaves finely and sprinkle them evenly over the tomatoes.

Step 7

In a medium mixing bowl, combine the breadcrumbs, grated Parmesan cheese, and remaining olive oil. Mix until the breadcrumbs are evenly coated with the oil.

Step 8

Melt the butter in a small saucepan or microwave-safe dish. Drizzle it over the breadcrumb mixture and stir well to incorporate.

Step 9

Spread the breadcrumb mixture evenly over the top of the tomatoes, ensuring it covers the entire surface.

Step 10

Place the dish in the preheated oven and bake for 20-25 minutes, or until the topping is golden brown and the tomato juices are bubbling around the edges.

Step 11

Remove from the oven and let the gratin cool for 5 minutes before serving.

Step 12

Serve warm as a standalone dish or as a side alongside roasted meats, grilled fish, or crusty bread.
