Key Ingredients for Vegetarian Spinach and Mushroom Quiche
Here’s what you’ll need to make this scrumptious quiche:
- 1 ready-made pie crust (store-bought or homemade)
- 2 cups fresh spinach (washed and chopped)
- 1 cup mushrooms (sliced, your choice: button, cremini, or portobello)
- 1 medium onion (finely chopped)
- 3 large eggs
- 1 cup heavy cream (you can substitute with a non-dairy alternative if preferred)
- 1 cup shredded cheese (cheddar or mozzarella work brilliantly)
- Salt and pepper (to taste)
- 1/2 teaspoon garlic powder (optional for extra flavor)
- 1 tablespoon olive oil (for sautéing)
Step-by-Step Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Prepare the Filling: In a skillet, heat the olive oil over medium heat. Add the chopped onions and sauté until translucent. Then, add the sliced mushrooms and cook until they’re soft and golden, about 5-7 minutes. Stir in the chopped spinach and cook for another 2 minutes until wilted. Season with salt, pepper, and garlic powder (if using).
- Make the Custard: In a bowl, whisk together the eggs and heavy cream until well blended. Add half of the cheese, reserving the other half for later.
- Combine: Stir the sautéed vegetable mixture into the egg mixture until everything is evenly coated.
- Assemble the Quiche: Pour the filling into the prepared pie crust and sprinkle the remaining cheese on top.
- Bake: Place the quiche in the preheated oven and bake for 30-40 minutes, or until the center is set and the top is golden brown. Let it cool for a few minutes before slicing.
- Serve: Slice and enjoy your Vegetarian Spinach and Mushroom Quiche warm or at room temperature!
Top Tips for Perfecting Vegetarian Spinach and Mushroom Quiche
- Substitutions: For a twist, you can swap the spinach for kale or add in other vegetables like bell peppers or zucchini. Feel free to mix and match based on what you have!
- Timing: Be sure to allow the quiche to cool a bit before slicing; this helps it set properly.
- Common Mistakes: Avoid overcooking the eggs! They should be just set in the middle. If they look slightly jiggly, that’s okay; they will continue to cook while cooling.
Storing and Reheating Tips
To store your leftover Vegetarian Spinach and Mushroom Quiche, simply cover it tightly with plastic wrap or aluminum foil and refrigerate. It will last for about 3-4 days. If you wish to freeze it, wrap it well and store it for up to 2 months. To reheat, thaw it overnight in the fridge and warm it in the oven at 350°F (175°C) for about 15-20 minutes until heated through, ensuring your crust remains flaky and your filling stays moist.
Creating this Vegetarian Spinach and Mushroom Quiche isn’t just about making food; it’s about crafting a cozy experience that you can share with family and friends!
