What is Tomato Pie?

Tomato pie is a savory, cheesy dish layered with slices of fresh tomatoes, herbs, and a creamy cheese topping, all baked in a flaky crust. It has Southern roots but has seen creative interpretations across different regions, from rustic Italian versions to minimalist French tartes.

It’s best enjoyed in summer, when tomatoes are at their peak, and it’s the perfect way to use up the abundance from your garden or farmer’s market haul.

Key Ingredients Overview

A classic tomato pie starts with simple, fresh ingredients:

Fresh ripe tomatoes: The star of the show. Heirloom or Roma tomatoes work best.
Pie crust: Use a pre-made crust for ease, or make your own for maximum flavor.
Mayonnaise: Gives the pie its signature creamy topping.
Cheese: A blend of mozzarella and Parmesan is traditional, but you can mix in sharp cheddar or provolone.
Fresh herbs: Basil and oregano add brightness.
Onion: A layer of sliced or sautéed onion gives it a subtle bite.

Preparation Tips to Avoid a Soggy Crust

One of the most common complaints with tomato pie is a soggy bottom crust. Here’s how to avoid it:

Pre-bake the crust: Also called blind baking, this firms up the crust before adding the wet filling.
Salt and drain the tomatoes: Slice the tomatoes and place them on paper towels. Sprinkle with salt and let them drain for 30-45 minutes.
Blot with paper towels: This helps remove excess moisture.
Brush the crust with egg whites: This adds a protective layer to resist sogginess.
Add breadcrumbs or cheese under the tomatoes: These absorb liquid during baking.

Ingredients:

1 (9-inch) pie shell
