Instructions

Prepare the Crust:
- Pre-bake a deep-dish pie crust (store-bought or homemade) according to package or recipe instructions (typically 10-12 minutes at 375°F/190°C). Let cool slightly.
- Tip: Prick the crust with a fork before baking to prevent puffing.
Cook the Bacon:
- Cook 6-8 slices thick-cut bacon until crispy, then drain on paper towels and crumble. Set aside.
- Tip: Save a little bacon grease to cook the onions for extra flavor.
Caramelize the Onions:
- In a skillet over medium-low heat, cook 1 large thinly sliced yellow onion in 1-2 tbsp bacon grease or olive oil until soft and golden, about 15 minutes. Stir occasionally.
- Let cool slightly.
- Tip: Low and slow cooking ensures sweet, caramelized onions without burning.
Prepare the Cheese Topping:
- In a medium bowl, mix 1 1/2 cups shredded mozzarella, 1/2 cup mayonnaise, 1/2 cup sour cream, 1 tbsp flour, 1/2 tsp garlic powder, 1/4 tsp black pepper, and 1/4 tsp salt until smooth.
- Tip: Stir until fully combined to avoid a grainy texture.
Assemble the Pie:
- Spread the caramelized onions evenly over the pre-baked crust.
- Sprinkle the crumbled bacon over the onions.
- Layer 2 medium tomatoes, thinly sliced, over the bacon, overlapping slightly if needed.
- Spread the cheese mixture evenly over the tomatoes, covering the filling completely.
- Tip: Pat tomato slices dry with paper towels to reduce excess moisture.
Bake:
- Preheat the oven to 350°F (175°C).
- Bake the pie for 25-30 minutes, until the topping is golden and bubbly.
- Tip: Place the pie on a baking sheet to catch any drips.
Garnish and Serve:
- Let the pie cool for 5-10 minutes, then sprinkle with 1 tbsp chopped fresh chives or parsley (optional).
- Slice into 6-8 wedges and serve warm or at room temperature.
- Health Benefit: Tomatoes provide vitamin C and antioxidants, but this rich pie is best enjoyed as a comforting treat!
