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

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Heat the butter and olive oil in a large skillet over medium heat.

Step 3

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.

Step 4

Add the baby spinach to the skillet and cook for 2-3 minutes, stirring until wilted. Remove from heat and set aside.

Step 5

In a medium mixing bowl, whisk together the eggs, heavy cream, milk, thyme, salt, and pepper until well combined.

Step 6

Place the prepared pie crust on a baking sheet for easier handling. Spread the caramelized onions evenly across the bottom of the crust.

Step 7

Layer the wilted spinach on top of the onions, followed by the crumbled feta cheese.

Step 8

Pour the egg mixture over the fillings, ensuring the liquid is evenly distributed.

Step 9

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.

Step 10

Let the quiche cool for 10 minutes before slicing and serving. Enjoy!
