How to Make Caramelized Onion Feta And Spinach Quiche

  1. Preheat oven to 375°F (190°C).
  2. Prepare the caramelized onions: In a large skillet over medium heat, melt 2 tablespoons of butter. Add 2 large onions, thinly sliced, and cook, stirring occasionally, until deeply caramelized (about 20-25 minutes). Set aside.
  3. Prepare the crust: If using store-bought crust, roll it out and place into a 9-inch pie dish. If making your own, follow your preferred recipe.
  4. In a large bowl, whisk together 4 large eggs, 1 cup of heavy cream, 1/2 cup of grated Gruyere cheese, 1/4 teaspoon of salt, and 1/4 teaspoon of black pepper.
  5. Add 5 oz of crumbled feta cheese, 5 oz of fresh spinach (roughly chopped), and the caramelized onions to the egg mixture. Stir gently to combine.
  6. Pour the egg mixture into the pie crust.
  7. Bake for 45-50 minutes, or until the quiche is set and golden brown. Let cool for 10-15 minutes before slicing and serving.
  8. Garnish with fresh parsley or chives (optional).
