When I first prepared this quiche, I was aiming for a dish that combined simple ingredients with maximum flavor. The secret lies in the freshness of the spinach and mushrooms—using high-quality ingredients makes a noticeable difference. I remember that each layer of the quiche, from the crust to the filling, contributes to a wonderful balance of textures and flavors.

If you want to impress your guests, let the quiche rest for a few minutes after baking. This not only enhances the flavors but also allows for easier slicing, making it a beautiful centerpiece for any table. Trust me, it’s worth the wait!

Understanding the Ingredients

The base of this quiche features simple yet essential ingredients for both flavor and texture. Fresh spinach not only adds a vibrant color but also contributes essential nutrients like iron and vitamins A and C. Mushrooms, on the other hand, provide an earthy depth, balancing the greens with their umami flavor. When selecting mushrooms, consider using a mix of button and cremini for a richer taste, or even sautéing some garlic with them for added aroma.

The choice of cheese can greatly impact the overall flavor profile of your quiche. While sharp cheddar is a popular option, experimenting with varieties like Gruyère or feta can introduce intriguing new tastes. If you're looking to cut down on fat but still want a creamy texture, try substituting half the cream with whole milk or plant-based milk alternatives like cashew milk, which can also lend a nutty flavor and creamy consistency.

Perfecting Your Crust

A successful quiche starts with a well-made crust. For an extra flaky texture, ensure your butter is very cold before cutting it into the flour, as warm butter can lead to a tough crust. Additionally, avoid overworking the dough; mix until just combined. If you find your crust is too crumbly, add a teaspoon of cold water at a time until it holds together without being wet or sticky. Refrigerating the dough is crucial, as it allows the gluten to relax and prevents shrinkage during baking.

To pre-bake your crust for a crispier texture, remove it from the refrigerator, prick the base with a fork, and bake it at 375°F (190°C) for about 10 minutes before adding your filling. This step will help prevent a soggy bottom, especially with a creamy filling like this one. Remember to keep an eye on the crust as it bakes; it should begin to turn a light golden color, signaling that it's ready for the next step.

Ingredients

For the Crust

1 1/2 cups all-purpose flour
1/2 cup unsalted butter, chilled and diced
1/4 cup cold water
1/2 teaspoon salt

For the Filling

1 cup fresh spinach, chopped
1 cup mushrooms, diced

1/4 teaspoon nutmeg

Mix and match vegetables to suit your taste!

Instructions

Prepare the Crust

In a mixing bowl, combine flour and salt. Cut in the butter until the mixture resembles coarse crumbs. Stir in the cold water gradually until the dough forms. Wrap in plastic and refrigerate for 30 minutes.

Preheat the Oven

Preheat your oven to 375°F (190°C).

Roll Out the Dough

On a floured surface, roll out the dough to fit a 9-inch pie plate. Place the dough in the pie plate and trim the edges.

Prepare the Filling

In a skillet, sauté the mushrooms until they are tender, about 5 minutes. Add spinach and cook until wilted. In a bowl, whisk together the eggs, cream, salt, pepper, and nutmeg.

Assemble the Quiche

Spread the sautéed vegetables over the crust and pour the egg mixture on top. Sprinkle with cheese.

Bake

Bake for 30-35 minutes or until the quiche is set in the center and lightly golden on top. Let it cool for 10 minutes before slicing.

Let your quiche cool slightly for better slicing.

Serving and Pairing Ideas

This Spinach Mushroom Quiche is incredibly versatile when it comes to serving options. Whether you're enjoying it warm or at room temperature, it pairs beautifully with a light side salad dressed in a tangy vinaigrette, complementing the richness of the quiche. For added protein, consider serving it alongside smoked salmon or a handful of roasted almonds, which also introduce a satisfying crunch to your meal.

If you're cooking for a crowd, this quiche slices beautifully, making it easy to serve. To elevate the brunch experience, consider offering a spread of condiments such as sour cream, fresh herbs, or a homemade salsa on the side. These additions can help balance the creaminess of the quiche and allow guests to personalize their portions.

Make-Ahead and Storage Tips

If you're planning a busy brunch, this quiche is perfect for make-ahead preparation. You can assemble the entire dish a day in advance, cover it with plastic wrap, and refrigerate until you're ready to bake it. For best results, bake it fresh, but if you need to make it a day ahead, bake it fully, cool it, and then store it in the refrigerator. Just remember to reheat it in the oven at 350°F (175°C) for about 20 minutes until heated through, ensuring a fresh taste and texture.

Leftover quiche can be stored in an airtight container in the refrigerator for up to three days. If you’d like to freeze it, slice the quiche first, wrapping each piece tightly in plastic wrap and then placing them in a freezer-safe bag. It can be stored this way for up to two months. When you're ready to enjoy a piece, heat it directly from frozen, adding about 15-20 minutes to your bake time.
