Classic Baked Tomato Pie with Mozzarella and Fresh Basil

This savory tomato pie combines the peak flavors of summer with layers of ripe tomatoes, creamy mozzarella, and fresh basil in a flaky pie crust. The tomatoes are salted to draw out excess moisture, ensuring a perfectly set filling rather than a soggy bottom. The mayonnaise and cheese mixture creates a rich, tangy topping that bubbles golden in the oven. Perfect for summer gatherings, potlucks, or as a unique side dish when tomatoes are at their best. This Southern-inspired dish transforms simple ingredients into an impressive centerpiece that celebrates the essence of fresh tomatoes.
