Recipe Steps:

  1. Preheat the Oven:
    • Preheat your oven to 375°F (190°C). If using a store-bought pie crust, follow the package instructions for pre-baking.
  2. Prepare the Pie Crust:
    • Roll out your pie crust and fit it into a 9-inch pie dish. Trim any excess dough and crimp the edges. Prick the bottom with a fork. Line with parchment paper and fill with pie weights or dried beans. Blind bake for 10 minutes, then remove weights and parchment, and bake for an additional 5 minutes until lightly golden. Let cool.
  3. Cook the Vegetables:
    • In a large skillet, heat 1 tablespoon of olive oil or butter over medium heat. Add 1 finely chopped onion and cook until softened, about 5 minutes. Add 2 minced garlic cloves and cook for another minute. Add 8 ounces of sliced mushrooms and cook until they release their moisture and become tender, about 5-7 minutes. Add 2 cups of fresh spinach and cook until wilted. Season with salt and pepper. Remove from heat and let cool slightly.
  4. Prepare the Custard:
    • In a medium bowl, whisk together 4 large eggs, 1 cup of heavy cream, 1/2 cup of milk, 1 cup of shredded cheese, a pinch of nutmeg (if using), and salt and pepper to taste.
  5. Assemble the Quiche:
    • Spread the cooked spinach and mushroom mixture evenly over the bottom of the pre-baked pie crust. Pour the egg mixture over the top, ensuring it is evenly distributed.
  6. Bake:
    • Place the quiche in the preheated oven and bake for 35-40 minutes, or until the center is set and the top is golden brown. If the crust edges brown too quickly, cover them with foil or a pie shield.
  7. Cool and Serve:
    • Allow the quiche to cool for at least 10 minutes before slicing. Serve warm or at room temperature.

Storage Options:

  • Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
  • Freeze: Wrap the baked quiche tightly in plastic wrap and aluminum foil. Freeze for up to 2 months. Thaw in the refrigerator overnight and reheat in the oven.
