Instructions

  1. Step 1: Preheat the oven to 375°F. Heat 2 tbsp olive oil in a skillet over medium heat and add 1 medium thinly sliced yellow onion. Sauté for 8-10 minutes until golden and caramelized, stirring occasionally.
  2. Step 2: Add 4 cups fresh spinach to the skillet and cook for 2-3 minutes until wilted. Remove from heat and set aside.
  3. Step 3: In a mixing bowl, whisk together 4 large eggs, 1 cup heavy cream, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp ground nutmeg until smooth.
  4. Step 4: Place 1 (9-inch) pie crust into a pie dish. Spread half of the spinach and onion mixture evenly over the crust, then sprinkle 1/2 cup crumbled feta cheese on top.
  5. Step 5: Pour half of the egg mixture over the first layer, then repeat with the remaining spinach-onion mixture and feta, and finish by pouring the rest of the egg custard on top.
  6. Step 6: Bake in the preheated oven for 35-40 minutes until the quiche is set and the top is lightly golden. Allow to cool for 10 minutes before slicing.
