My grandma’s kitchen always smelled like sunshine and basil in the summer, and I swear, that’s where my love for a good tomato pie started. I remember watching her, flour dusting her apron, and then one year, she just skipped the crust! Honestly, I was a bit confused, like, is it even a pie without a crust? But then came my first bite of Crustless Southern tomato Pie, and oh my word, it was magic. It’s got all that cheesy, savory comfort without the fuss, and it just tastes like home to me.

I still laugh thinking about the first time I tried to make this Crustless Southern Tomato Pie myself. I totally forgot to drain the tomatoes properly, and let's just say it was more soup than pie. Oops! My husband still jokes about my 'tomato soup in a dish' incident. But hey, we all learn, right? Now, I’ve got my routine down, and it’s a dish I make without even thinking, often with a glass of sweet tea nearby.

Ingredients for Your Crustless Southern Tomato Pie

  • Ripe Tomatoes (about 3-4 large, or 5-6 medium): You need fresh, ripe, summer tomatoes for this. Honestly, don't even think about using those pale, wintery ones, it just won't taste the same. I usually go for beefsteaks or heirlooms, sliced about 1/4 inch thick.
  • Mayonnaise (1/2 cup): This is the binder and the secret to that rich, tangy custard-like texture. Don't use light mayo, just don't. Full-fat only, please! I swear by Duke's or Hellmann's for that authentic Southern kick.
  • Shredded Cheddar Cheese (1 cup): Sharp cheddar is my go-to for its robust flavor, but a medium cheddar works too. Freshly shredded is always better than pre-shredded, it melts so much nicer.
  • Shredded Mozzarella Cheese (1/2 cup): This adds a lovely melt and stretch to the pie. Sometimes I'll throw in a little Gruyere if I'm feeling fancy, it worked... kinda, adding a nuttier note.
  • Parmesan Cheese (1/4 cup, grated): Just a little sprinkle for a salty, umami boost. It really wakes up the cheesy flavor. I always keep a wedge in the fridge for grating on everything.
  • All-Purpose Flour (2 tablespoons): This helps bind the cheese mixture and thickens any residual tomato juices. I once forgot it, and the pie was a bit too watery, a minor kitchen disaster, but still tasty!
  • Fresh Basil (1/4 cup, chopped): The smell of fresh basil with tomatoes is just heavenly. It's non-negotiable for me. I grow it in a pot on my patio, so it's always handy.
  • Onion (1/2 cup, thinly sliced or finely diced): I like a sweet Vidalia onion here, sliced super thin so it almost melts into the pie. It adds a subtle sweetness and aromatic depth.
  • Garlic (2 cloves, minced): Because everything is better with garlic, right? I usually add a little more than the recipe calls for, honestly.
  • Salt & Freshly Ground Black Pepper (to taste): Seasoning is key! I always use coarse sea salt for the tomatoes to help draw out moisture.

How to Assemble Your Crustless Southern Tomato Pie

Prep the Tomatoes:
First things first, those beautiful tomatoes need a little spa treatment. Slice them about 1/4 inch thick, then lay them out on a few layers of paper towels. Sprinkle them generously with salt this is where I always remember to be heavy-handed! Let them sit for at least 30 minutes, or even an hour. You'll see pools of water forming, and honestly, that's what we want. Gently blot them dry with more paper towels. This step is crucial, it stops your Crustless Southern Tomato Pie from getting watery, a mistake I learned the hard way.
Mix the Cheesy Goodness:
In a medium bowl, combine the mayonnaise, shredded cheddar, shredded mozzarella, grated Parmesan, and flour. Give it a good stir until everything is nicely combined and looks like a thick, cheesy paste. This is the heart of our pie! Add your minced garlic and a good pinch of black pepper here too. I sometimes toss in a tiny dash of hot sauce for a little zing, just a secret little something I do. It adds a warmth you didn't expect.
Layer It Up:
Grab a 9-inch pie dish no need to grease it, just plop your ingredients right in! Start with a layer of those blotted tomato slices on the bottom. Overlap them slightly, like shingles on a roof. Then, sprinkle a small amount of your thinly sliced onion and some fresh basil over the tomatoes. Oh, the smell starts to get amazing at this point!
Add the Cheese Layer:
Now, spoon about half of your cheesy mayonnaise mixture over that first layer of tomatoes, onion, and basil. Spread it out as evenly as you can. It's a bit sticky, but just go with it. This creates a creamy, rich layer that holds everything together beautifully. I usually use the back of a spoon to gently spread it, trying not to squish the tomatoes too much.
Repeat and Top:
Repeat the layering process: another layer of tomato slices, followed by the rest of the sliced onion and basil. Then, spread the remaining cheesy mixture over the top. Make sure it covers most of the tomatoes, creating that beautiful, golden crust. Sometimes I get a little messy here, with cheese bits everywhere, but it all bakes into deliciousness, so who cares?
Bake to Golden Perfection:
Pop your pie dish into a preheated oven at 375°F (190°C). Bake for about 35-45 minutes, or until the top is golden brown and bubbly, and the edges are set. Your kitchen will smell absolutely incredible! When it comes out, let it rest for at least 10-15 minutes before slicing. This resting time is key, it lets the pie set up, so it doesn't fall apart when you cut into it.

There's something so satisfying about pulling this Crustless Southern Tomato Pie out of the oven, all golden and bubbly. It makes the whole house smell like summer. I remember one time, I was so excited, I pulled it out and immediately tried to cut it. Big mistake! It completely collapsed. Now, I always make myself wait, even though it's hard when it smells that good!

Storing Your Crustless Southern Tomato Pie

This pie keeps surprisingly well, which is great because sometimes I make a big one just for leftovers. Once it's completely cooled (and I mean completely!), cover it tightly with plastic wrap or pop it into an airtight container. It'll hang out happily in the fridge for about 3-4 days. Now, here's a personal tip: I tried reheating a slice in the microwave once, and the cheese got a bit rubbery, and the sauce separated so don't do that lol. Instead, I always recommend reheating gently in a preheated oven at around 300°F (150°C) for about 15-20 minutes until it's warmed through and the cheese is soft again. It brings back that lovely texture without drying it out or making it weird.

Crustless Southern Tomato Pie Ingredient Swaps

I’m all about experimenting in the kitchen, especially when I'm missing an ingredient or just want to try something new with this Crustless Southern Tomato Pie. For the cheese, I've tried a mix of Gruyere and Monterey Jack once when I was out of cheddar, and it worked... kinda. It was delicious, just a different flavor profile. Feel free to swap out the cheddar for a sharp white cheddar or even a smoked gouda for a different twist. If you don't have fresh basil, you can use about 1 tablespoon of dried basil, but honestly, fresh is always superior here. For the onion, shallots can be a nice, milder substitute. I’ve even thrown in some chopped green onions for a sharper bite. It’s your kitchen, your rules!

Serving Your Crustless Southern Tomato Pie

This Crustless Southern Tomato Pie is a star on its own, but it plays well with others too! For a simple weeknight meal, I love serving it with a crisp green salad tossed in a tangy vinaigrette, that freshness really cuts through the richness of the pie. A side of grilled corn on the cob or some simply steamed green beans with a pat of butter also makes for a lovely, light addition. If I'm feeling extra, a dollop of fresh pesto on top of each slice just before serving is an absolute game-changer. And for drinks? A tall glass of iced tea, sweet or unsweet, feels just right. Or, honestly, this dish and a rom-com? Yes please. It’s perfect for a laid-back, comforting evening.

Frequently Asked Questions

→ Can I use canned tomatoes for this Crustless Southern Tomato Pie?

Honestly, I wouldn't recommend it. This pie really shines with fresh, ripe summer tomatoes. Canned tomatoes will release too much liquid and change the texture quite a bit, making it watery. Stick to fresh for the best results!

→ What if I don't have all the cheeses listed?

No worries! I've tried various cheese combinations. As long as you have a good melting cheese like cheddar or mozzarella as the base, you can play around. A sharp provolone or even some Monterey Jack would probably work, too. Just experiment!

→ How do I prevent my tomato pie from being watery?

Ah, the age-old question! The absolute key is salting and draining your tomato slices thoroughly. Don't rush this step. I've made the mistake of skipping it, and my pie was more like a casserole. Let those tomatoes sweat out their extra liquid!

→ Can I make this Crustless Southern Tomato Pie ahead of time?

You can prep the tomato slices and the cheese mixture separately a day ahead. Just store them in the fridge. Assemble and bake the pie right before you want to serve it for the freshest taste and best texture. A warm pie is always better!

→ Are there any other vegetables I can add to this tomato pie?

I've seen people add thinly sliced zucchini or bell peppers, but I find they can add extra moisture. If you do, make sure to salt and drain them well, just like the tomatoes. A little bit of corn could be a fun addition too, but I prefer to keep it classic.
