Here's another quiche. I enjoy making them because quiches are perfect for using up leftovers from your fridge or for creating a more refined dish. This particular quiche is both sweet and savory, featuring a delightful mix of bacon, caramelized onions, and Gruyere cheese.
Annotated Cooking Notes: Preparing a quiche is more like baking than cooking, so it's important to be precise with your measurements.
Ingredients
- 1 pre-made pie crust (store-bought or homemade)
- 4 large eggs
- 1 cup heavy cream
- 1 cup shredded Gruyère cheese
- 1 large onion, thinly sliced
- 6 slices beef bacon, chopped into small pieces
- 1 tablespoon olive oil
- 1 teaspoon fresh thyme leaves
- Salt and pepper to taste
- Fresh parsley for garnish
Directions
Instructions:
1. Preheat your oven to 375°F (190°C).
2. In a skillet, heat the olive oil over medium heat. Add the chopped beef bacon and cook until crispy. Remove and set aside, leaving the drippings in the pan.
3. In the same skillet, add the sliced onions and cook over low heat, stirring occasionally, until they are caramelized (about 15-20 minutes). Add the thyme, salt, and pepper to taste.
4. In a mixing bowl, whisk together the eggs and heavy cream until well combined. Stir in the shredded Gruyère cheese, caramelized onions, and crispy beef bacon.
5. Pour the mixture into the pie crust, spreading it evenly.
6. Bake in the preheated oven for 30-35 minutes, or until the quiche is set and lightly golden on top.
7. Allow to cool slightly before slicing. Garnish with fresh parsley for a pop of color!
