Layered Bacon Tomato Onion Pie is what I make when the tomatoes on the counter are too ripe and fragrant to ignore. It bakes up savory and rich, with crisp bacon tucked between tomato slices and a golden cheddar topping that bubbles at the edges.
The key is not fancy pastry work. It is patience with the tomatoes. Give them time with salt, blot them well, and the filling tastes bright instead of watery.
Tomatoes, bacon, and pie basics
Choose tomatoes that smell sweet at the stem and feel heavy for their size. This is a simple pie, so the filling depends on ripe tomatoes, crisp bacon, and cheese with enough sharpness to cut through the creamy topping.
- Ripe tomatoes. They make the layered filling juicy and bright, but salting and draining keeps that juice from soaking the crust.
- Bacon. Crisp pieces add smoke, salt, and crunch between the soft tomato layers.
- Sweet onion. A quick skillet cook softens the bite and brings out mellow sweetness.
- Deep-dish pie crust. A blind-baked shell gives the pie structure and a flaky base.
- Cheddar cheese. Sharp cheddar melts into the topping and forms a golden cap.
- Mozzarella. A small amount adds stretch without making the pie too sharp.
- Mayonnaise and sour cream. They bind the cheese into a savory topping that melts into the layers.
- Basil and thyme. Fresh herbs keep the rich bacon and cheese from tasting heavy.
- Dijon mustard. A little tang sharpens the creamy topping.
Layered Bacon Tomato Onion Pie Method
- Drain the tomatoes. Slice the tomatoes, sprinkle with salt, and let them sit on towels or in a colander for 30 minutes. Blot them well so the pie bakes savory instead of soupy.
- Blind bake the crust. Fit the crust into a deep 9-inch pie plate, prick the base, line it with parchment, and bake with pie weights until lightly set. This gives the bottom enough strength for the filling.
- Cook bacon and onion. Crisp the bacon, then cook the onion in a little bacon fat until soft and lightly golden. The onion should be tender, not dark.
- Mix the topping. Stir mayonnaise, sour cream, Dijon, cheddar, mozzarella, pepper, and herbs into a thick spread. It should look like a loose pimento cheese.
- Build the layers. Scatter a little cheese over the crust, then layer tomatoes, onion, bacon, and basil. Repeat once more and spread the cheese topping over the pie.
- Bake and rest. Bake until deeply golden and bubbling at the edges. Let the pie rest before slicing so the cheese sets around the tomato layers.
The no-soggy-crust move
Tomatoes carry a lot of water, which is why a beautiful tomato pie can turn loose in the pan. Salting the slices pulls moisture to the surface. The technique is common in Southern-style tomato pie recipes, and this tomato pie guide also points to draining and concentrating tomatoes as the make-or-break step.
Do not skip the blotting after the tomatoes drain. The salt does its job, but the towel removes the liquid. Blind baking matters too. If you like this tomato-and-crust style, the site's Tomato and Corn with Flaky Crust has the same summer-pie comfort with a meatless filling.
Layering for cleaner slices
The bottom of the pie gets a light scatter of cheese before the tomatoes go in. It melts into a thin barrier and adds flavor right where the crust needs help. Keep the bacon crisp before layering, since soft bacon disappears into the filling.
When you spread the topping, leave a few tomato edges showing. The topping will melt and settle. If it is piled all the way to the rim, it can bubble over before the center is hot. For a cheesier bacon bake with a very different personality, try Bacon Cheeseburger Pan Lasagna.
Smart swaps that fit
Use a red onion if you want a sharper bite or Vidalia onion for a sweeter pie. Monterey Jack can replace mozzarella, and a little Parmesan can stand in for part of the cheddar. I would not use all Parmesan because the topping gets too salty with the bacon.
For a lighter version, use turkey bacon and swap half the mayonnaise for Greek yogurt. The texture will be tangier and less glossy, but it still bakes well. For a salad that uses the same tomato and onion pairing in a cooler way, serve it with Marinated Cucumber Tomato Onion Salad.
Safe prep and storage
Wash tomatoes under running water before slicing, even if you do not eat the stem end. The FDA gives the same basic advice in its produce safety guidance. Once baked, let the pie cool for serving, but do not leave leftovers out all afternoon.
Store slices in an airtight container in the refrigerator for up to 3 days. FoodSafety.gov's cold storage chart is a useful reference for cooked leftovers. Reheat slices on a sheet pan at 325°F until warm. The crust stays better that way than it does in the microwave.
Serving it without fuss
This pie is best warm, not scorching hot. Fresh from the oven, the filling is too loose and the tomato flavor is muted by heat. After 20 to 30 minutes, the slices hold their shape and the bacon tastes more pronounced.
Serve it with a sharp salad, grilled corn, or a bowl of fruit. If you are building a bacon-heavy brunch spread, Grilled Cheese with Bacon and Oven-Dried Tomato keeps the same smoky tomato theme.
Summary
This savory pie is best warm or at room temperature with a simple green salad. It is sturdy enough for a summer supper, brunch table, or potluck.
FAQs
- How do I keep tomato pie from getting watery?
Slice the tomatoes, salt them, and let them drain for at least 30 minutes. Blot both sides before layering. A blind-baked crust and a thin layer of cheese on the bottom also help block extra juice.
- Can I use a store-bought pie crust?
Yes. A refrigerated 9-inch deep-dish crust works well here. Blind bake it first so it has a head start before the juicy filling goes in.
- What kind of tomatoes are best?
Use ripe beefsteak, Roma, or heirloom tomatoes. Roma tomatoes are less watery, while heirlooms give the prettiest top layer. If your tomatoes are extra juicy, drain them a little longer.
- Can I make Layered Bacon Tomato Onion Pie ahead?
You can bake it a few hours ahead and serve it warm or at room temperature. For the cleanest slices, let it rest at least 20 minutes after baking. Refrigerate leftovers within 2 hours.
- Can I make it without bacon?
Yes. Skip the bacon and cook the onions in olive oil or butter. Add smoked paprika or a pinch of chipotle powder if you still want a little smoky flavor.
- What should I serve with tomato onion pie?
A crisp salad is enough because the pie is rich. Try cucumber salad, coleslaw, or simple greens with vinaigrette. It also works well beside grilled chicken or iced tea for a casual summer meal.
