Bacon, Onion, and Tomato Pie

by

Introduction

This Bacon, Onion, and Tomato Pie is a celebrated staple of high-summer dining, capturing the essence of a garden harvest in a flaky, buttery crust. Often referred to as “Southern Tomato Pie,” this version is elevated by the addition of smoky, thick-cut bacon and sweet caramelized onions, which provide a savory counterpoint to the bright, acidic juiciness of vine-ripened tomatoes. The filling is bound together by a velvety, herb-infused cheese topping that browns beautifully in the oven. It is a rustic, colorful centerpiece that works perfectly as a sophisticated brunch dish or a light, seasonal dinner served on the patio.

Ingredients

The Foundation

  • 1 (9-inch) Deep-Dish Pie Crust: Pre-baked and cooled. (Store-bought or homemade).
  • 3 to 4 Large Tomatoes: Firm but ripe (Roma or Beefsteak work best).
  • 8 slices Bacon: Cooked until crispy and crumbled.
  • 1 large Yellow Onion: Thinly sliced and caramelized.
  • 1/2 cup Fresh Basil: Chopped.

The Creamy Topping

  • 1 cup Sharp Cheddar Cheese: Freshly shredded.
  • 1/2 cup Parmesan Cheese: Grated.
  • 1/2 cup Mayonnaise: (The secret for a rich, stable binder).
  • 1 tsp Garlic Powder
  • Salt and Black Pepper: To taste.

Equipment Needed

  • 9-inch Deep-Dish Pie Plate
  • Large Skillet: For the bacon and onions.
  • Colander and Paper Towels: For draining the tomatoes.
  • Medium Mixing Bowl: To whisk the cheese topping.

Preparation Time, Cooking Time, Total Time, Servings

  • Prep Time: 25 minutes (includes tomato draining)
  • Cook Time: 30 to 35 minutes
  • Total Time: Approx. 1 hour
  • Servings: 6 to 8 slices

Step-by-Step Instructions

1. The Tomato “Dry-Out” (Crucial Step)

Preheat your oven to 350°F (175°C). Slice your tomatoes into 1/4-inch rounds. Lay them out in a single layer on a double thickness of paper towels. Sprinkle lightly with salt and let them sit for 15–20 minutes. Pat the tops dry with more paper towels.

Note: Removing this moisture prevents the pie from becoming watery and ensures a crisp bottom crust.

2. Sauté the Aromatics

In a skillet, cook the bacon until crispy. Remove and crumble. In the remaining bacon fat (drain all but 1 tablespoon), sauté the sliced onions over medium-low heat for about 10–12 minutes until they are soft and golden brown.

3. Layer the Pie

In your pre-baked crust, spread the caramelized onions in an even layer. Top with half of the crumbled bacon and half of the chopped basil. Arrange the dried tomato slices over the top in an overlapping circular pattern. Repeat with the remaining bacon and basil.

4. The Cheese Canopy

In a medium bowl, stir together the cheddar, parmesan, mayonnaise, garlic powder, and black pepper. Dollop the mixture over the tomatoes and spread it gently to the edges of the crust.

5. Bake to a Golden Glow

Bake for 30 to 35 minutes. The pie is done when the cheese topping is bubbling and has developed a beautiful, speckled golden-brown crust.

6. The Essential Rest

Let the pie sit for at least 15 to 20 minutes before slicing. This is vital for the layers to “set” so you get a clean, beautiful wedge rather than a messy scoop.

Tips and Tricks

  • Tomato Choice: Roma tomatoes are excellent because they have a lower water content than many other varieties.
  • Pre-Bake Your Crust: Always “blind bake” your crust before adding the tomatoes to prevent the dreaded “soggy bottom.”
  • Fresh Basil: Use fresh basil rather than dried; the aromatic oils in fresh leaves provide the necessary brightness to cut through the heavy cheese and mayo.

Variations

  • Corn and Tomato Pie: Add 1 cup of fresh corn kernels (sautéed with the onions) for extra sweetness.
  • Hot & Savory: Add a finely diced jalapeño or a dash of hot sauce to the cheese mixture.
  • Pesto Twist: Spread a thin layer of pesto on the bottom of the crust before adding the onions.

Serving Suggestions

This pie is best served warm or at room temperature. It pairs wonderfully with a simple arugula salad or a cold cucumber soup. It is a fantastic accompaniment to grilled shrimp or can stand alone as a light summer meal.

Storage Instructions

  • Refrigeration: Store in an airtight container for up to 3 days.
  • Reheating: Reheat in a 325°F oven for 10–15 minutes. Microwaving is not recommended as it can make the crust soft and the tomatoes mushy.
