Ingredients
- Pie crust
- 1 (9-inch), store-bought or homemade
- Olive oil
- 2 tablespoons
- Onion
- 2 medium, thinly sliced
- Mushrooms
- 8 ounces, sliced (any variety such as cremini or button)
- Garlic
- 2 cloves, minced
- Fresh thyme
- 1 tablespoon, chopped (or 1 teaspoon dried thyme)
- Salt
- 1/2 teaspoon, plus more to taste
- Black pepper
- 1/4 teaspoon, freshly cracked, plus more to taste
- Eggs
- 3 large
- Milk
- 1/2 cup
- Gruyère cheese
- 1 cup, grated
Instructions
- Preheat the oven to 375°F (190°C).
- Roll out the pie crust and carefully press it into a 9-inch tart pan. Trim any excess crust, and use a fork to prick the base to prevent bubbling during baking.
- In a large skillet, heat the olive oil over medium heat. Add the sliced onions and sauté, stirring occasionally, until they become caramelized and golden brown, about 10 minutes.
- Stir in the sliced mushrooms, minced garlic, chopped thyme, salt, and pepper. Cook for an additional 5 minutes until the mushrooms are tender and any released liquid has evaporated.
- In a separate mixing bowl, whisk together the eggs and milk until well combined. Season with a pinch of salt and pepper.
- Spread the caramelized onion and mushroom mixture evenly over the prepared pie crust.
- Pour the egg mixture over the filling, ensuring an even distribution across the tart.
- Generously sprinkle the grated Gruyère cheese on top of the tart.
- Bake in the preheated oven for 25-30 minutes, or until the tart is set and golden brown on top.
- Allow the tart to cool for a few minutes before slicing. Serve warm with a simple green salad dressed in olive oil and lemon juice for a refreshing complement.
Tips
- For added richness, consider adding a splash of heavy cream to the egg mixture.
- You can mix in other vegetables such as spinach or leeks for additional flavor and nutrition.
- This tart can be made ahead of time and served at room temperature, making it perfect for gatherings.
