The first time I made tomato pie, I almost didn’t. I’d picked up a basket of overripe heirloom tomatoes at the farmers market — the kind that are too soft for sandwiches and too juicy for salad — and I had no idea what to do with them. A neighbor took one look at my haul and said, “Girl, that’s a pie waiting to happen.” She was right. One bite of that warm, cheesy, tomato-soaked slice and I was hooked for good.
If you’ve never made a tomato pie before, you’re in for a treat. It’s savory, it’s rustic, and it’s ridiculously forgiving — the kind of recipe that turns a pile of ripe tomatoes into a dinner people ask about for weeks. Whether you grew up watching a grandmother assemble one every August or you’re discovering the dish for the first time, there’s a reason this old-fashioned recipe keeps finding its way back onto dinner tables. This guide walks you through the whole process, step by step, plus the tricks that keep it from turning into a soggy mess (more on that in a minute).
What Exactly Is Tomato Pie?
Tomato pie means a few different things depending on where you’re standing. In Philadelphia and parts of Pennsylvania, the term often refers to a thick, square, focaccia-like pizza topped with a bold tomato sauce and little to no cheese — a completely different animal from what we’re making today. Head south, though, and it becomes something else entirely: a flaky pie crust layered with sliced tomatoes, herbs, and a rich, baked mayonnaise-cheese topping that turns golden and bubbly in the oven. That Southern-style version is the one home cooks fall in love with, and it’s the recipe I’m sharing below.
Whichever regional version you grew up with, the appeal is the same: it’s a way to celebrate tomatoes at their absolute best, without letting a single one go to waste.

Step-by-Step: How to Make Tomato Pie
Step 1: Salt and drain the tomatoes
This is the step nobody wants to skip if they want a pie that holds its shape. Lay your sliced tomatoes on a baking sheet lined with paper towels, sprinkle them with the kosher salt, and let them sit for 20 to 30 minutes. The salt pulls out excess water. Blot the tops dry before moving on — this single step is what separates a clean slice from a watery puddle.
Step 2: Pre-bake your crust
If you’re using a homemade or refrigerated pie crust, blind-bake it at 375°F for about 10 minutes, until it’s just starting to turn golden at the edges. A pre-baked crust holds up much better against all that tomato moisture than a raw one would.
Step 3: Layer the tomatoes and onion
Arrange half the drained tomato slices in the crust, followed by the sliced onion, then the remaining tomatoes. Season generously with black pepper as you go.
Step 4: Make the topping
In a medium bowl, stir together the mayonnaise, cheddar, mozzarella, basil, chives, and garlic powder until fully combined. This mixture is the heart of a good pie — it bakes into a golden, savory crust that ties everything together.
Step 5: Spread and bake
Spoon the cheese mixture evenly over the tomatoes, spreading it all the way to the edges of the crust to seal in the juices. Bake at 375°F for 30 to 35 minutes, until the top is deep golden brown and bubbling at the edges.
Step 6: Rest before slicing
Let your pie rest for at least 15 minutes before cutting in. I know that’s the hardest part, but the resting time lets the filling set so your slices come out clean instead of collapsing. Top with fresh basil and serve warm or at room temperature.
Tips for the Best Pie (No Soggy Crust!)
- Don’t skip the salting step. It’s tempting to rush straight to assembly, but those 20 minutes of draining make the biggest difference in the final texture.
- Use a slotted spoon when layering. Any liquid left on your cutting board should stay there, not go into the pie.
- Let it cool before slicing. A pie that’s cut too soon will always look messier than it tastes.
- Swap the cheese if you like. Gruyère or a smoked cheddar both work beautifully if you want to change things up.
Key Takeaways
- This dish means different things regionally — this recipe is the Southern-style version, with a pie crust and baked cheese topping.
- Salting and draining your tomatoes is the single most important step for a firm, sliceable pie.
- A pre-baked crust and a short resting period after baking are what keep this dish from turning watery.
- It’s endlessly adaptable — swap cheeses, herbs, or crust styles to make it your own.
Frequently Asked Questions
Do you peel the tomatoes for a tomato pie?
It’s not required, but many cooks prefer to peel them for a smoother bite and to reduce extra moisture from the skins. If you’d like to peel yours, score an X on the bottom of each tomato, drop them in boiling water for 30 seconds, then transfer to an ice bath — the skins will slip right off.
What cheese is best for tomato pie?
A blend of sharp cheddar and mozzarella is the classic choice because it melts smoothly and adds a savory depth without overpowering the tomatoes. Gruyère, Monterey Jack, or a smoked cheddar are all great substitutions if you want to experiment.
How do you keep tomato pie from being watery?
Salt and drain your tomato slices for at least 20 minutes before assembling, blot them dry, and always pre-bake your crust. Letting the finished pie rest for 15 minutes before slicing also gives the filling time to set.
Is tomato pie a Pennsylvania thing?
Sort of — but it depends which version you mean. In Pennsylvania, especially around Philadelphia, the term usually refers to a square, cold-served pizza with a bold tomato sauce and light cheese. The layered, mayonnaise-topped version in this recipe is more closely associated with Southern home cooking, though both share the same tomato-loving spirit.
Final Thoughts
There’s something a little magical about turning a basket of ripe, slightly-too-soft tomatoes into a dish this good. It isn’t fussy, it isn’t fancy, and it doesn’t need to be — it just needs good tomatoes, a little patience with the salting step, and an oven. Slice it thick and serve it warm alongside a simple green salad, or let it cool completely and enjoy a slice the next morning with your coffee — leftovers, if there are any, taste just as good cold straight from the fridge. Once you’ve made your first tomato pie, I promise it becomes a late-summer ritual you’ll look forward to every year, the kind of recipe you scribble on an index card and hand down without thinking twice.
