Ingredients

  • 1 Refrigerated Pie Crust
  • 2 cups Spinach
  • 1 cup Mushrooms diced
  • 5 Eggs
  • 1 cup Whole Milk
  • 1 cup Swiss Cheese shredded
  • 2 cloves Garlic minced
  • 1/2 cup Onion chopped
  • 1/2 tsp Salt
  • 1/4 tsp Black Pepper
  • 2 tbsp Olive Oil
  • 1/4 tsp Nutmeg

Instructions

  • Prepare the Crust. Preheat the oven according to the pie crust package instructions. Place the pie crust in a pie dish and crimp the edges. Partially bake the crust until lightly golden, then set aside.
  • Sauté the Vegetables. In a skillet, heat olive oil over medium heat. Add minced garlic and chopped onion, sauté until softened. Add sliced mushrooms and cook until they release their moisture. Stir in chopped spinach and cook until wilted. Remove from heat and let cool slightly.
  • Prepare the Filling. In a mixing bowl, whisk together eggs, milk, salt, pepper, and a pinch of nutmeg (if using). Stir in shredded Swiss cheese and the sautéed vegetable mixture until well combined.
  • Assemble and Bake. Pour the egg mixture into the partially baked pie crust, spreading it evenly. Place the quiche in the preheated oven and bake until the filling is set and the top is golden brown, about 30-35 minutes.
  • Serve and Enjoy. Once baked, remove the quiche from the oven and let it cool for a few minutes before slicing. Garnish with fresh herbs if desired. Serve warm or at room temperature.
