Recipe Information
Ingredients
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 large yellow onion
- 4 cups baby spinach
- 4 large eggs
- 1 cup heavy cream
- 0.5 cup whole milk
- 1 cup feta cheese
- 1 teaspoon fresh thyme leaves
- 0.5 teaspoon salt
- 0.25 teaspoon black pepper
- 1 prepared 9-inch deep-dish pie crust
Instructions
Preheat your oven to 375°F (190°C).
Heat the butter and olive oil in a large skillet over medium heat.
Slice the onions thinly and add them to the skillet. Cook for 25-30 minutes, stirring occasionally, until the onions are golden brown and caramelized. Set aside to cool slightly.
Add the baby spinach to the skillet and cook for 2-3 minutes, stirring until wilted. Remove from heat and set aside.
In a medium mixing bowl, whisk together the eggs, heavy cream, milk, thyme, salt, and pepper until well combined.
Place the prepared pie crust on a baking sheet for easier handling. Spread the caramelized onions evenly across the bottom of the crust.
Layer the wilted spinach on top of the onions, followed by the crumbled feta cheese.
Pour the egg mixture over the fillings, ensuring the liquid is evenly distributed.
Carefully transfer the quiche to the oven and bake for 40-45 minutes, or until the center is set and the top is lightly golden.
Let the quiche cool for 10 minutes before slicing and serving. Enjoy!
