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.

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.

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!

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 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?

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.
