Key takeaways
- 1 9-inch refrigerated or homemade pie crust
- 2½–3 pounds ripe but firm tomatoes
- 1 teaspoon kosher salt, divided
- 1 cup shredded sharp cheddar cheese
- 1 cup shredded low-moisture mozzarella
- ½ cup mayonnaise
- ¼ cup finely grated Parmesan cheese
- 2 tablespoons chopped fresh basil, plus more for serving
- 2 tablespoons thinly sliced green onions or scallions
- ½ teaspoon black pepper
- 1 tablespoon cornmeal or fine breadcrumbs
- 1 egg, beaten, for brushing the crust
For a crisp tomato pie, drain salted tomato slices for 30–45 minutes, pre-bake the crust, layer cheese between the tomatoes and crust, and bake first at 425°F before finishing at 375°F.
Tomato Pie Recipe at a Glance
| Item | Amount or timing | Why it matters |
|---|---|---|
| Pie crust | 1 unbaked 9-inch crust | Provides a sturdy base for the filling |
| Tomatoes | 2½–3 pounds, sliced ¼ inch thick | Enough for a full pie after moisture loss |
| Tomato draining time | 30–45 minutes | Removes water before it reaches the crust |
| Blind-baking temperature | 425°F for 15 minutes | Sets the crust before the wet filling is added |
| Final baking temperature | 375°F for 30–35 minutes | Melts the cheese without burning the crust |
| Resting time | At least 30 minutes | Lets the filling firm up for cleaner slices |

How to Make Tomato Pie Without a Soggy Crust
1. Slice and drain the tomatoes
Choose firm tomatoes rather than very soft, overripe ones. Roma tomatoes release less water, while ripe slicing tomatoes provide a more traditional flavor; either works if you drain them carefully.

Slice the tomatoes about ¼ inch thick. Arrange them in a single layer on a rimmed baking sheet or several layers of paper towels. Sprinkle both sides lightly with the kosher salt. Let them stand for 15 minutes, then turn them and continue draining for another 15–30 minutes.
After 30–45 minutes total, blot the slices firmly with additional paper towels. They should still look juicy, but they should not leave a large wet patch when pressed. Do not skip the blotting step: draining pulls out liquid, while blotting removes the surface moisture that would otherwise soak into the crust.
2. Blind-bake the crust
Heat the oven to 425°F. Fit the crust into a 9-inch pie plate, pressing it firmly into the corners. Fold or crimp the edge, then chill the shaped crust for 15–20 minutes.
Line the crust with parchment and fill it with pie weights, dried beans, or uncooked rice. Bake for 15 minutes. Remove the parchment and weights, brush the bottom and sides with beaten egg, and bake for 3–5 minutes more, until the base looks dry and the edge is lightly colored.
Brush the egg over the hot crust carefully. It forms a thin moisture-resistant layer, while the cornmeal or breadcrumbs added later provide another barrier beneath the tomatoes.
3. Choose a cheese-layer strategy
Combine the mayonnaise, Parmesan, black pepper, basil, and green onions in a small bowl. The mixture will become the creamy topping. Keep the cheddar and mozzarella separate so you can build layers.
| Cheese approach | Best for | Trade-off |
|---|---|---|
| Cheddar on the bottom, mozzarella on top | Maximum crust protection and a mild finish | Less sharp flavor in each bite |
| Mozzarella on the bottom, cheddar on top | Long cheese pull with a stronger browned topping | Can become greasy if the mozzarella is fresh and wet |
| Cheddar plus Parmesan throughout | A sharper, more savory pie | Less stretchy and slightly saltier |
| Low-moisture mozzarella only | A lighter, less assertive filling | Needs herbs or extra seasoning for more flavor |
For the most reliable crust, use the first option: sharp cheddar directly above the crust, followed by the tomatoes, then mozzarella and the mayonnaise mixture near the top. Low-moisture mozzarella is preferable to fresh mozzarella because it releases less water during baking.
4. Layer the pie
Reduce the oven temperature to 375°F. Sprinkle the blind-baked crust with the cornmeal or breadcrumbs. Add about one-third of the cheddar, then arrange one layer of drained tomatoes over it, slightly overlapping the slices.
Repeat with another third of the cheddar and a second layer of tomatoes. Finish with the remaining cheddar. Spread the mayonnaise mixture evenly over the top, then sprinkle on the mozzarella.
Do not pile all the tomatoes in the center. A level, evenly distributed filling cooks more consistently and allows steam to escape around the edges. If your tomatoes are unusually large or wet, use fewer slices rather than forcing an extra layer into the pie.
5. Bake and cool
Place the pie on a rimmed baking sheet to catch bubbling cheese. Bake at 375°F for 30–35 minutes, until the top is golden and the center looks set rather than liquid. If the crust edge browns too quickly, shield it with a strip of aluminum foil after the first 15 minutes.
Cool the pie for at least 30 minutes before slicing. For the neatest wedges, wait 45–60 minutes. The filling will still be warm, but the cheese and tomato juices will have thickened enough to stay inside the crust.
Make-Ahead Instructions
- Up to 24 hours ahead: Blind-bake the crust, cool it completely, and store it covered at room temperature. Shred the cheeses and mix the mayonnaise topping separately in the refrigerator.
- Up to 8 hours ahead: Slice and salt the tomatoes, drain them for 30–45 minutes, blot them, and refrigerate them in a single layer between dry paper towels.
- For same-day assembly: Assemble the pie no more than 2 hours before baking. Keep it refrigerated, then place it in the preheated oven while still cold; add approximately 5 minutes to the final bake if needed.
- For leftovers: Refrigerate covered for up to 3 days. Reheat individual slices at 375°F for 10–15 minutes, preferably on a preheated baking sheet, rather than microwaving them.
Kitchen Setup Details That Make This Recipe Easier
Tomato pie uses more counter space than its ingredient list suggests. A 24-inch-wide clear prep area is enough for one pie, a draining tray, and a mixing bowl; a 30–36-inch stretch is more comfortable if you are preparing a salad or side dish at the same time. Keep the draining tray close to the sink, but leave at least 4 inches of clearance around the pie plate so the hot dish can be moved safely.
A standard 9-inch pie plate is usually about 1½–2 inches deep. If using a deeper 9½-inch dish, do not automatically add more tomatoes: the extra volume can increase the baking time and leave the center watery. Instead, drain the tomatoes longer, use a thin final layer, and look for a set center rather than relying only on the clock.
Troubleshooting Tomato Pie
Why is the bottom crust still wet?
The tomatoes may have needed more time, or they may not have been blotted after draining. Next time, drain them for 45 minutes, use low-moisture cheese, and extend the blind bake until the base looks dry. A metal pie plate also transfers heat more quickly than a thick ceramic dish.
Why did the topping separate?
Very wet tomatoes or fresh mozzarella can release enough liquid to thin the mayonnaise mixture. Use low-moisture mozzarella, avoid overfilling the pie, and let it rest before cutting.
Can the pie be frozen?
It is best baked fresh. Freezing assembled tomato pie can make the tomatoes watery and the crust soft after thawing. If necessary, freeze a fully baked, cooled pie for up to 1 month, reheat it from frozen at 350°F until hot, and expect a softer crust than with a same-day bake.
This tomato pie recipe works best when moisture is managed at every stage: drain the tomatoes, protect the crust with an egg wash and cheese, bake at two temperatures, and give the finished pie time to set before serving.
