Instructions

Start by preheating your oven to 375°F (190°C). Place the pie crust in a 9-inch pie dish and gently press it into the dish, crimping the edges if you like. Partially prebake the crust for about 8 minutes to prevent a soggy bottom later.

Meanwhile, warm the olive oil in a skillet over medium heat. Add the sliced mushrooms and sauté until they begin to release their moisture, about 5 to 7 minutes. Stir in the minced garlic and spinach, cooking just until the spinach wilts. Remove from heat and let the mixture cool slightly.

In a medium bowl, whisk together the eggs, half-and-half (or milk), salt, black pepper, and a pinch of nutmeg if you enjoy a subtle, cozy spice. Spread the mushroom and spinach mixture evenly in the partially baked crust, then sprinkle the shredded cheese on top. Slowly pour the egg mixture over everything, ensuring it coats the filling.

Carefully place the quiche in the oven and bake for about 35 to 40 minutes, or until the filling is set in the center and the crust is golden. Allow the quiche to cool for a few minutes before slicing it into wedges.
