Description
Onion Tomato Pie is a savory Southern-style dish made with fresh tomatoes, caramelized onions, herbs, and a cheesy topping baked in a flaky pie crust — perfect as a side or light main course.
Ingredients
Scale
- 1 9-inch pie crust (store-bought or homemade)
- 3–4 medium ripe tomatoes, sliced
- 2 medium onions, thinly sliced
- 1 tbsp olive oil
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp dried basil or thyme
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup mayonnaise or Greek yogurt
- 2 tbsp chopped fresh parsley or green onions (for garnish)
Instructions
- Preheat oven to 375°F (190°C). Blind bake the pie crust for 8–10 minutes, then set aside to cool slightly.
- In a skillet, heat olive oil over medium heat. Add sliced onions and cook for 10–15 minutes until caramelized. Season with salt and pepper.
- Layer half the tomato slices in the pie crust. Sprinkle with a bit of salt and pepper.
- Spread the caramelized onions evenly over the tomatoes. Add the remaining tomato slices on top.
- In a small bowl, mix mozzarella, Parmesan, and mayonnaise (or Greek yogurt). Spread the cheese mixture evenly over the top layer.
- Bake for 30–35 minutes until golden and bubbly. Let rest for 10 minutes before slicing.
- Garnish with fresh parsley or green onions and serve warm or at room temperature.
Notes
- Use heirloom tomatoes for extra flavor and color.
- Salt tomato slices and let them drain on paper towels before assembling to avoid sogginess.
- Pairs well with a light green salad or grilled meats.
