This tomato and basil casserole is a simple yet flavorful dish that celebrates the freshness of summer tomatoes and aromatic basil. Sliced tomatoes are layered with fresh basil leaves and a mixture of breadcrumbs, Parmesan cheese, and garlic. The casserole is then baked until the tomatoes are tender and the breadcrumb topping is golden and crispy. The combination of juicy tomatoes, fragrant basil, and crunchy breadcrumbs creates a delightful contrast of flavors and textures. Serve this casserole as a side dish or as a light vegetarian main course for a taste of summer all year round.
