When I first attempted this quiche, I was amazed at how simple yet satisfying it was. The key is to make sure the spinach and mushrooms are well-seasoned before adding them to the eggs. This helps to maximize flavor and ensures that every bite is delicious. Using fresh ingredients makes a noticeable difference!

Over time, I’ve experimented with different herbs and spices, and I can say that a hint of nutmeg really elevates the taste. I love pairing it with a light green salad for a refreshing complement.

Choosing the Right Ingredients

When selecting the spinach for your quiche, opt for fresh, vibrant leaves. Wilted or yellowed spinach can negatively impact the flavor and texture. If you're short on time, you can substitute frozen spinach; just be sure to thoroughly drain and squeeze out excess moisture to avoid a soggy quiche.

For the mushrooms, varieties such as cremini or button mushrooms provide a great earthy flavor. Sauté them until they're nicely browned to enhance their sweetness. This caramelization step is crucial as it adds depth to the dish. Remember also to slice them evenly for uniform cooking.

Perfecting the Baking Process

Baking your quiche at the right temperature ensures a flaky crust and a well-cooked filling. Make sure your oven is fully preheated to 375°F (190°C) before placing the quiche inside to avoid a soggy bottom. A good visual cue is the crust should be golden brown, indicating it's baked through.

To check if your quiche is done, gently jiggle the pan; the center should be set but slightly wobbly, as it will continue to firm up as it cools. If you notice that the edges are browning too quickly, cover them with strips of aluminum foil to prevent burning while the center finishes baking.

Ingredients

Gather the following ingredients to prepare your quiche:

Ingredients for Quiche

1 pre-made pie crust
2 cups fresh spinach, chopped
1 cup mushrooms, sliced
1 medium onion, diced
4 large eggs
1 cup heavy cream
1 cup shredded cheese (cheddar or Swiss)
Salt and pepper to taste
1 teaspoon olive oil
1/2 teaspoon nutmeg

Make sure all ingredients are prepped before you start cooking to ensure a smooth process!

Instructions

Follow these steps to create your quiche:

Preheat the Oven

Preheat your oven to 375°F (190°C).

Sauté Vegetables

In a skillet, heat olive oil over medium heat. Add onions and sauté until translucent. Add mushrooms and spinach, season with salt, pepper, and nutmeg, and cook until the spinach is wilted.

Prepare Egg Mixture

In a bowl, whisk together the eggs, heavy cream, and half of the cheese. Stir in the sautéed vegetables.

Assemble Quiche

Pour the vegetable and egg mixture into the pie crust. Sprinkle the remaining cheese on top.

Bake

Bake the quiche in the preheated oven for 35-40 minutes or until the center is set and the top is golden brown.

Cool and Serve

Allow the quiche to cool for a few minutes before slicing. Serve warm or at room temperature.

Don’t forget to let your quiche rest for a minute before serving; this helps it set and makes cutting easier!

Pro Tips

Experiment with different vegetables or herbs to customize your quiche. Leftover quiche keeps well in the fridge for 3-4 days and also freezes beautifully.

Storage and Reheating Tips

To store your leftover quiche, wrap it tightly in plastic wrap or place it in an airtight container. It can last in the refrigerator for up to three days. For longer preservation, consider freezing it. Slice the quiche before freezing for easier reheating—a quiche can be frozen for up to two months.

To reheat, simply pop it in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until warmed through. If you're in a rush, you can microwave slices for 1-2 minutes, but this may result in a softer crust. I prefer the oven method for maintaining that flaky texture.

Variations and Creative Twists

Feel free to experiment with different cheeses! Feta or goat cheese can add a tangy twist, while incorporating herbs such as thyme or basil can elevate the flavors even further. Adding a layer of cooked bacon or ham can introduce a savory richness, making it irresistibly delicious.

For a lighter version, consider substituting half of the cream with milk, which still provides creaminess without being overly rich. You can also add roasted red peppers or sun-dried tomatoes to the mix for an extra pop of flavor and color.
