Bacon Onion Tomato Pie is the perfect bridge between summer comfort and hearty flavor. When garden tomatoes peak and everyone craves something savory and satisfying, this pie always finds its way onto my table. Creamy and crisp with smoky bacon and sweet onions, it is a celebration of simple ingredients that tastes like you fussed all afternoon.
I fell in love with this pie while searching for a cozy brunch dish and it quickly became the surprise hit of our family gatherings. It is one of those recipes that disappears fast and everyone asks for the secret.
Ingredients
- Deep-dish pie crust: Look for a sturdy frozen or refrigerated crust so it can hold the generous filling
- Thick-cut bacon: Quality bacon gives the best flavor and texture Try to buy from the butcher or choose a brand with minimal additives
- Large yellow onion: Sweet onions balance the bacon You want clear layers and no mushy spots
- Medium tomatoes: Choose ripe but firm tomatoes Drain on paper towels to avoid a soggy pie
- Shredded cheddar cheese: Sharp cheddar works best Shred it yourself if possible for better melt and flavor
- Mayonnaise: Adds richness and helps create that creamy top Use a good quality mayo for best taste
- Sour cream: Brings tang which brightens the filling Full fat sour cream works best
- Salt and pepper: Essential for seasoning Taste as you assemble especially if your bacon is salty
Step-by-Step Instructions
- Prepare the Pie Crust:
- Place the deep-dish pie crust in your pie pan Make sure edges are pressed firmly and allow to chill while you prepare the filling It prevents shrinking
- Cook the Bacon:
- Fry the thick-cut bacon over medium heat until brown and crispy Transfer to a paper towel lined plate and let cool Crumble into bite-sized pieces
- Sauté the Onions:
- Slice onions thinly then cook them slowly over medium-low heat until soft and golden about ten to twelve minutes This builds a sweet savory base for the pie
- Prep the Tomatoes:
- Slice medium tomatoes and let them drain on paper towels Pat tops dry You want the tomatoes juicy but not dripping for the perfect slice later
- Layer the Filling:
- Scatter the sautéed onions on the bottom of your chilled pie crust Layer the drained tomato slices and top with crumbled bacon Make sure each layer is even
- Mix the Creamy Topping:
- In a bowl blend together shredded cheddar cheese mayonnaise and sour cream until smooth Season lightly with salt and pepper Spoon this mixture over the layered filling and smooth with a spatula
- Bake to Perfection:
- Bake the assembled pie at three hundred seventy five degrees until the top is golden and the filling bubbles around the edges about thirty to thirty five minutes
- Cool Before Slicing:
- Let the pie cool at least fifteen minutes before slicing It helps the cheesy top set and makes serving cleaner

The cheese topping forms a rich almost spreadable layer my kids beg for around lunch time The smell always reminds me of weekends at my aunt’s house where this pie was her signature brunch dish and everyone tried to sneak seconds
