Mushroom, Spinach, and Swiss Cheese Quiche
This quiche is delicious for breakfast with fresh fruit or for dinner with a simple tossed salad.
Ingredients
- 2 tbsp salted butter
- 1/3 cup finely diced white onion
- 10 oz mushrooms, sliced
- 2 cups baby spinach
- 6 large eggs
- 1 cup heavy cream
- 1 tsp garlic powder
- 1 tsp sea salt
- 1 tsp freshly ground black pepper
- 12 oz Swiss cheese, grated
- 1 unbaked pie crust, or a 9" store-bought pie crust
Instructions
- Preheat the oven to 350°.
- In a large sauté pan, heat the butter over medium heat until melted. Add the onion and sauté until tender, about 5 minutes. Add the mushrooms and cook until the liquid evaporates, about 5 minutes. Add the spinach and sauté until wilted, about one minute. Remove from heat.
- In a large bowl, whisk together the eggs, cream, garlic powder, salt, and pepper. Stir in the spinach/mushroom mixture and the Swiss cheese. Pour the mixture into the unbaked pie shell.
- Bake until the quiche is lightly golden and set in the center, about 45-60 minutes depending on ingredients. Test doneness by pushing the pan to see if the center is set.
- Remove from oven and let stand 5-10 minutes before cutting into 6-8 slices.
- Serve warm or at room temperature.
