When I first made this quiche, I was amazed at how simple it was to prepare yet packed with flavor! I sautéed the mushrooms until they were caramelized, which really brought out their depth and added a richness to the dish. Then I folded in the spinach, giving it that vibrant green hue that looked so inviting.

One of my favorite things about this quiche is that it can be enjoyed warm or at room temperature, making it perfect for gatherings. I’ve even changed up the cheeses I've used, and each time it turns out wonderfully delicious!

Perfecting the Crust

A great quiche begins with a well-prepared crust. If you're using a pre-made pie crust, it's important to follow package instructions for blind baking if recommended, as this helps prevent a soggy bottom. Ensure your crust is thawed if frozen and has been pressed into the pie dish evenly. If you're feeling adventurous, homemade pie crust can add an extra layer of flavor and flakiness. A mix of butter and shortening is often ideal for achieving that light, flaky texture.

When placing the crust in the pie dish, gently lift it to avoid stretching, which can result in shrinkage during baking. If you notice any cracks or holes after pressing it in, use some of the scrap dough to patch them up. Remember to poke holes in the bottom with a fork—this helps steam escape during baking and keeps your crust crisp.

If you like a deeper flavor, consider pre-baking your crust with a sprinkle of cheese inside. This adds an extra dimension and prevents the filling from making it too soggy. Bake it at 375°F (190°C) for about 10 minutes before adding the filling for an optimally crispy quiche base.

Vegetable Variations

While fresh spinach and mushrooms bring a great balance of flavor, don’t hesitate to explore different vegetables! Broccoli, bell peppers, or even zucchini can be excellent substitutes. Make sure to sauté any firm vegetables you choose—for about 3 to 5 minutes—before adding them to the quiche to ensure they are tender and release excess moisture.

In addition to swapping the vegetables, you can customize your cheese choice. Goat cheese adds a tangy richness, while mozzarella offers a lighter, stretchier texture. If you're looking to reduce calories or make a dairy-free quiche, using a plant-based cheese along with silken tofu blended until creamy can create a delightful alternative that still binds the filling together.

Remember, the key to preventing a watery quiche lies in your vegetable selection and preparation. Avoid overloading on watery produce, and be sure to pat them dry with a paper towel after cooking before they hit the pie crust.

Ingredients

Gather all the fresh ingredients for your quiche before you start cooking.

For the Quiche

1 pre-made pie crust
2 cups fresh spinach, chopped
1 cup mushrooms, sliced
4 large eggs
1 cup milk
1 cup shredded cheese (cheddar or your choice)
Salt and pepper to taste
1 tablespoon olive oil

Once you have everything ready, you can easily assemble your quiche!

Instructions

Follow these steps to create your delicious quiche.

Preheat the Oven

Preheat your oven to 375°F (190°C).

Sauté the Vegetables

In a skillet, heat olive oil over medium heat. Add sliced mushrooms and cook until they are golden brown, about 5-7 minutes. Stir in the chopped spinach and cook just until wilted. Remove from heat and set aside.

Prepare the Egg Mixture

In a bowl, whisk together the eggs and milk until well combined. Season with salt and pepper.

Assemble the Quiche

Place the pre-made pie crust into a pie dish. Spread the sautéed spinach and mushrooms evenly on the bottom. Pour the egg mixture over the vegetables and top with shredded cheese.

Bake

Bake in the preheated oven for 30-35 minutes, or until the egg is set and the top is golden.

Cool and Serve

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

Enjoy your homemade quiche with a side salad or fresh fruit!

Pro Tips

For an extra flavor boost, consider adding herbs like thyme or dill to the egg mixture. You can also replace the fillings with your favorite vegetables or leftover meats. This quiche can be made ahead of time and reheated, making it a great meal prep option.

Make-Ahead and Storage

One of the best aspects of this quiche is its make-ahead potential. You can assemble the quiche the day before and store it covered in the refrigerator. This allows the flavors to meld beautifully overnight. Just remember to add an extra 5-10 minutes to your bake time if you're starting with a chilled quiche fresh from the fridge.

If you’re looking to prepare multiple quiches, they freeze exceptionally well! Bake them fully, let them cool, and wrap each quiche tightly in plastic wrap followed by aluminum foil. They can be frozen for up to 3 months. To reheat, unwrap and bake from frozen at 350°F (175°C) for about 45 minutes, or until heated through. This makes for a quick weekday breakfast option.

Always check for doneness by inserting a knife into the center—it should come out clean. This quiche not only holds its texture well after freezing, but the flavors can even become more pronounced once thawed.

Serving Suggestions

This quiche pairs wonderfully with a light salad or a fruit platter for brunch. I love to serve it alongside a simple arugula salad dressed with lemon vinaigrette to cut through the creaminess. This balance enhances the overall dining experience, making it feel fresh and light.

For a more filling meal, consider adding hash browns or roasted potatoes as a side. The crispy texture contrasts nicely with the softness of the quiche, bringing your meal to another level. If you’re feeling indulgent, sprinkle fresh herbs like chives or dill on top of the quiche right before serving for a pop of color and flavor.

Lastly, don’t underestimate the power of a good hot sauce or salsa on the table. A drizzle can elevate your quiche experience, providing an extra kick that pairs beautifully with the creamy filling.
