• 8 slices bacon, cooked and crumbled
• 1 large onion, thinly sliced
• 1 tablespoon olive oil
• 1 teaspoon salt
• ½ teaspoon black pepper

For the Cheese Topping

• 1 cup shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• ½ cup mayonnaise
• 1 teaspoon dried basil
• 1 teaspoon garlic powder

Optional Garnish

How to Make Bacon Onion Tomato Pie

Step 1: Prepare the Tomatoes

Slice the tomatoes into approximately ¼-inch thick slices.

Lay them on paper towels and sprinkle lightly with salt.

Allow the tomatoes to sit for 20 to 30 minutes. This process helps remove excess moisture and prevents the pie from becoming soggy.

Afterward, gently pat the tomato slices dry with additional paper towels.

Step 2: Pre-Bake the Pie Crust

Preheat your oven to 375°F (190°C).

Place the pie crust into a 9-inch pie dish.

Using a fork, prick the bottom several times.

Bake the crust for 8 to 10 minutes until lightly golden.

Remove from the oven and allow it to cool slightly.

Step 3: Cook the Bacon

While the crust is baking, cook the bacon in a skillet over medium heat until crisp.

Transfer the cooked bacon to a paper towel-lined plate and crumble once cooled.

Reserve a small amount for garnish if desired.

Step 4: Caramelize the Onions

In the same skillet, remove excess bacon grease, leaving about one tablespoon behind or substitute with olive oil.

Add the sliced onions and cook over medium-low heat for approximately 12 to 15 minutes.

Stir occasionally until the onions become soft, golden, and slightly caramelized.

Remove from heat.

Step 5: Prepare the Cheese Mixture

In a medium bowl, combine:

• Shredded cheddar cheese
• Shredded mozzarella cheese
• Mayonnaise
• Dried basil
• Garlic powder

Mix until fully combined.

This creamy topping will create the signature golden crust on top of the pie.

Step 6: Assemble the Pie

Layer half of the tomato slices evenly across the bottom of the pre-baked crust.

Season lightly with black pepper.

Add half of the caramelized onions and half of the crumbled bacon.

Repeat with another layer of tomatoes, onions, and bacon.

Spread the cheese mixture evenly over the top, covering the entire surface.

Step 7: Bake

Place the assembled pie into the oven.

Bake for 30 to 35 minutes, or until the cheese topping becomes golden brown and bubbly.

The pie should be fully heated through and slightly firm in the center.

Step 8: Cool Before Serving

Allow the pie to rest for 10 to 15 minutes before slicing.

This helps the filling set and makes serving easier.

Garnish with fresh basil, parsley, or extra bacon if desired.

Tips for the Best Bacon Onion Tomato Pie

Use Ripe Tomatoes

Fresh, ripe tomatoes provide the best flavor and texture. Summer tomatoes are especially ideal for this recipe.

Remove Excess Moisture

Salting and draining the tomatoes is one of the most important steps. Skipping it may result in a watery pie.

Pre-Bake the Crust

Blind baking the crust helps maintain a crisp bottom and prevents sogginess.

Choose Quality Bacon

Thick-cut bacon adds extra texture and smoky flavor that complements the tomatoes beautifully.

Serving Suggestions

This pie is versatile enough to serve for various occasions.

Brunch

Pair with fresh fruit and scrambled eggs for a satisfying brunch menu.

Lunch

Serve with a crisp green salad and a light vinaigrette.

Dinner

Complement the pie with roasted vegetables or a simple soup.

Picnic or Potluck

Because it tastes great warm or at room temperature, it’s perfect for gatherings and outdoor events.

Variations

Southern Tomato Pie

Omit the bacon for a more traditional Southern-style tomato pie.

Spicy Version

Add diced jalapeños or a pinch of red pepper flakes to the filling.

Herb Lover’s Pie

Use fresh thyme, basil, and oregano for a more aromatic flavor profile.

Extra Cheesy Pie

Mix in Parmesan or Gruyère cheese for additional richness.

Storage and Reheating

Refrigeration

Store leftover pie covered in the refrigerator for up to 4 days.

Reheating

Warm slices in a 350°F (175°C) oven for 10 to 15 minutes to restore the crust’s texture.

Microwaving works as well, though the crust may become softer.

Freezing

The baked pie can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.

Nutritional Benefits

While this pie is undeniably indulgent, it also contains nutritious ingredients:

• Tomatoes provide vitamins A and C, antioxidants, and lycopene.
• Onions offer fiber and beneficial plant compounds.
• Cheese contributes calcium and protein.
• Bacon adds savory flavor and protein.

Balancing rich ingredients with fresh vegetables creates a dish that feels both comforting and satisfying.
