This tomato pie is Southern comfort at its best: roasted summer tomatoes, caramelized onions, melty cheese, and a buttery crust that never turns soggy.
Juicy summer tomatoes, melty cheese, and a buttery crust—what’s not to love about a Southern tomato pie? The best version I’ve ever had was at Lenoir, Vivian Howard’s restaurant in Charleston, so I was thrilled to find the recipe later in her wonderful cookbook, Deep Run Roots.
This is my simplified take on her recipe, but it follows the same smart method: roasting the tomatoes first to intensify their flavor and keep the crust from going soggy. I also keep things easy with a store-bought crust because who wants to fuss with a homemade pie crust in the heat of summer?
A thin layer of good-quality mayo mixed with fontina and Pecorino Romano melts over the top as it bakes, adding a creamy, tangy layer that brings the whole thing together. This is the kind of easy dish you’ll make on repeat all summer long.
“Outstanding! Now that I have tasted this, I want this on a weekly rotation!!!!”
What You’ll Need To Make Southern Tomato Pie
- Pie Crust (Frozen or Homemade): The buttery, crisp base for the filling. Stick with a standard 9-inch size—not deep-dish. For store-bought crusts that need blind baking, frozen ones in aluminum pans hold their shape best; if you’re worried about presentation, just slice and transfer to a nicer dish.
- Tomatoes, Onion, Olive Oil & Sugar: The savory base of the filling. Use ripe, in-season tomatoes for the best flavor. Seed to prevent sogginess, and roast with thinly sliced yellow onion, a drizzle of olive oil, and a pinch of sugar to deepen and balance the flavors.
- Thyme & Basil: Thyme gives the roasted veggies a savory, earthy boost (dried works just fine here), and fresh basil adds a pop of brightness at the end.
- Mayonnaise: Creates a creamy, tangy topping that sets tomato pie apart from a typical tart. Use good-quality mayo like Hellmann’s or Duke’s.
- Fontina & Pecorino Romano: Fontina melts beautifully while Pecorino brings sharp, salty flavor. Mozzarella and Parmesan are good substitutes, respectively, if that’s what you have.

How To Make Southern Tomato Pie
Blind bake the crust: Blind baking helps keep the crust crisp so it doesn’t get soggy under the juicy tomato filling. If using a frozen crust, prick it with a fork and bake until lightly golden. For homemade dough, line the crust with parchment, fill with pie weights, and bake until set, removing the weights toward the end so the crust can turn golden. Let cool slightly while you prepare the filling.
Roast the tomatoes and onions: Chop the tomatoes and thinly slice the onion, then toss with olive oil, seasonings, and thyme on a baking sheet. Spread into an even layer and roast until the tomatoes are slightly dried out and caramelized and the onions are lightly browned. Toss with fresh basil and set aside.
Make the topping: In a small bowl, stir together the mayonnaise, half of the fontina, and the Pecorino Romano until blended.
Assemble and bake the pie: Sprinkle the remaining fontina over the crust, then spread the tomato filling evenly on top. Dollop the mayo-cheese mixture over the tomatoes and gently spread it to the edges. Bake until lightly golden.
Serve: Let the pie cool slightly to help the filling set and make it easier to slice. Serve warm or at room temperature and enjoy!
Southern Tomato Pie
Ingredients
- 1 (9-in/23-cm) frozen or homemade pie crust (not deep-dish)
- 2 lbs tomatoes, cored, seeded, and cut into ¾-in (2-cm) pieces (I use vine-ripened)
- 1 large yellow onion, thinly sliced
- 2 tablespoons extra-virgin olive oil
- 1¼ teaspoons salt
- ¼ teaspoon freshly ground black pepper
- ¾ teaspoon sugar
- 1½ teaspoons fresh thyme leaves (or ½ teaspoon dried thyme)
- 2 tablespoons chopped fresh basil
- ½ cup mayonnaise
- 1 cup shredded fontina cheese (mozzarella can be substituted), divided
- ⅓ cup grated Pecorino Romano (Parmigiano-Reggiano can be substituted)
Instructions
- Blind bake the crust:If using a frozen crust: Preheat the oven to 375°F (190°C) and set a rack in the middle position. Remove the pie crust from the freezer and thaw until just soft enough to easily prick with a fork, about 10 minutes. Prick the bottom and sides all over with a fork (pricking about 1 inch/2.5 cm apart). Bake until fully cooked and lightly golden, 12 to 15 minutes. (Keep an eye on it; if it puffs up while cooking, gently prick it with a fork or press it down with a flat spatula so it will deflate.) Don't worry if the crust cracks while baking; see my note below on how to fix it before proceeding. Set the cooked crust aside as you prepare the filling. If using a homemade crust: Line the chilled dough with parchment paper and fill with pie weights or dried beans. Bake for 15 to 20 minutes, or until the edges are lightly golden and the crust is set. Carefully remove the weights and parchment. Return to the oven and bake until the crust is lightly golden and fully set, 5 to 10 minutes more.
- Roast the tomatoes and onions: Directly on a baking sheet, toss the tomatoes and onions with the olive oil, salt, pepper, sugar, and thyme. Spread in a single layer. Roast for 45 to 50 minutes, stirring a few times, until the tomatoes dry out and caramelize slightly and the onions are just slightly browned. Remove from the oven, sprinkle the basil over top, and mix to combine. Set aside.
- Prepare the cheese mixture: In a small bowl, stir together the mayonnaise, ½ cup (60 g) of the fontina, and the Pecorino Romano.
- Assemble the pie: Sprinkle the remaining fontina evenly over the bottom of the blind-baked crust. Spoon the roasted tomato filling over top and spread evenly into a compact layer. Dollop the mayo/cheese mixture over top and spread evenly to the edges (it will be a thin layer).
- Bake and serve: Bake the pie for 25 to 30 minutes, until lightly golden. Serve warm or at room temperature.
Notes
- When opting for a store-bought pie crust that requires blind baking, it’s best to use the frozen ones that come in aluminum pans. These crusts are molded into the pans, setting their shape and preventing shrinkage during baking. Conversely, rolled refrigerator crusts, which you fit into a pie dish yourself, can shrink if stretched or compressed. If you’re concerned about the aluminum pan’s appearance, pre-slice the pie and transfer the slices to a decorative pan or platter for a more elegant presentation.
- Don’t panic if your crust cracks during blind baking—you can easily fix it. Make a smooth paste by mixing 1½ tablespoons of flour with 1 tablespoon softened butter. Use your fingers to patch up and fill any cracks, then place the crust back in the oven for a minute or so to set. It should be good as new.

What To Serve With Tomato Pie
Tomato pie is pretty satisfying on its own, so I like to keep things light and summery on the side. A simple green salad, a cucumber salad, or some fresh watermelon sticks are all perfect pairings, especially on a hot day. A glass of hibiscus iced tea makes it even better.
Make-Ahead & REheating Instructions
You can blind bake the crust and roast the tomato-onion mixture up to a day ahead. Store them separately, then assemble and bake the pie when ready. The baked pie can sit at room temperature for several hours or be refrigerated overnight and served at room temperature or reheated. To freeze, cool the baked pie completely, wrap tightly in foil, and freeze for up to 1 month. Thaw overnight in the fridge, then reheat in a 350°F oven until warmed through.

Outstanding! My husband made this recipe and wow, I am floored. When he said he was making tomato pie, I didn’t even blink an eye. Now that I have tasted this, I want this on a weekly rotation!!!! It is so flavorful and delicious. I wouldn’t change a thing in this recipe. It is perfect!
I’ve been making a tomato pie for over 20 years now but it calls for raw tomatoes so we only make it in the summer with our homegrown. I bet this would work well for store bought tomatoes.
Question – can i eliminate the mayo? I can’t eat it!
Thanks
Unfortunately, that won’t work – sorry!
Haven’t tried this recipe yet but definitely will. Any suggestions as to pie crust brand? The quality varies so much. Would love your recommendation. Thanks!
Hi Jerri, I really like Wholly Wholesome brand. You can find it at Whole Foods. Hope you enjoy the pie!
So delicious! I made my own pie crust and blind baked in the morning and set it aside. Followed the recipe as written. This far exceeded my expectations. I will out in a plug for the very best mayonnaise anywhere, which is Blue Plate mayo. If your store has it, you should try it!
Can this be refrigerated or frozen before heating or reheating? Thank you!
Hi Libby, there are a number of make-ahead options, both for refrigerating and freezing. See the bottom of the recipe for specifics. Hope you enjoy if you make it!
Can I roast the tomatoes and onions a day ahead?
Yep!
I could not find a non – deep dish pie crust so made my own. I used up 2 lbs of home grown tomatoes and the result was delicious. I made it exactly as described – sooooo good. Thank you so much.
My 93 year old mother says she hasn’t had a decent tomato in 40 years (including the ones I grow!), and I’m inclined to agree. But with enough onions and cheese, anything is possible!
Charleston is such a great food town. When I was there 10 years ago, in every restaurant we went to, the chef would come out to check on us. We were flummoxed, because so not used to that.
This sounds delicious! Is there a specific store bought crust you recommend? Can’t wait to try this!
Hi Eileen, I like the Wholly Wholesome brand, which you can find at Whole Foods. 😊
am baking the tomato pie for dinner! What temperature to cook the pie with contents, please? Thank you
Hi Glenda, It’s 375°F. Hope you enjoy! 🙂
