Preheat your oven to 375°F (190°C).
Thinly slice the heirloom tomatoes into approximately 1/4-inch thick rounds, discarding the stem ends.
Grease the bottom of a 9-inch baking dish with 1 tablespoon of olive oil.
Arrange the tomato slices in the dish, slightly overlapping, to create an even layer.
Sprinkle the tomatoes with salt, black pepper, minced garlic, and fresh thyme leaves.
Chop the fresh basil leaves finely and sprinkle them evenly over the tomatoes.
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.
Melt the butter in a small saucepan or microwave-safe dish. Drizzle it over the breadcrumb mixture and stir well to incorporate.
Spread the breadcrumb mixture evenly over the top of the tomatoes, ensuring it covers the entire surface.
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.
Remove from the oven and let the gratin cool for 5 minutes before serving.
Serve warm as a standalone dish or as a side alongside roasted meats, grilled fish, or crusty bread.
