When I first made this quiche, I was amazed at how simple and satisfying it was. I sautéed the mushrooms and spinach to bring out their flavors, adding a sprinkle of nutmeg to enhance the earthy tones. It’s a brilliant method that ensures vibrant filling complements the creamy custard.

To achieve the perfect crust, I use a combination of flour and butter, then chill it before baking to ensure it holds its shape. The smell wafting through the kitchen as it bakes is pure bliss, making the effort totally worthwhile!

Choosing the Right Cheese

The choice of cheese can significantly impact the flavor and texture of your Spinach Mushroom Quiche. While cheddar provides a sharp taste, mozzarella offers a milder, creamier element. Don't hesitate to mix cheeses for a more complex profile. For instance, combining sharp cheddar with a tangy goat cheese can enhance the dish even further. Just ensure you use about one cup of cheese total to keep it balanced with the egg and cream mixture.

If you're looking for a lighter option, consider using reduced-fat cheese or a dairy-free alternative, like almond or cashew cheese. This adjustment may slightly alter the quiche's texture, making it creamier while still maintaining a rich flavor. Just make sure the cheese you choose melts well for that perfect gooey texture.

Perfecting the Crust

A flaky, golden crust is essential for a successful quiche. While using a pre-made pie crust saves time, homemade options can elevate the dish even more. If you choose to make your crust, use cold butter and ice water to ensure a tender, flaky texture. Aim for a consistency akin to wet sand before pressing it into the pie dish and chilling it for 30 minutes to prevent shrinking during baking.

If you're avoiding gluten, a gluten-free crust can work well. Make sure to press it firmly into your pie dish to avoid cracks. Another option is to make a crustless version by simply greasing the pie dish, which keeps the focus on the rich filling while also reducing carbs—a great choice for those following a low-carb diet.

Ingredients

For the Quiche

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

Instructions

Steps

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 onions and sauté for about 5 minutes until soft. Then add the mushrooms and cook for another 5 minutes. Finally, stir in the chopped spinach and cook until wilted. Season with salt, pepper, and nutmeg.

Make the Egg Mixture

In a mixing bowl, whisk together the eggs and heavy cream. Stir in the sautéed vegetables and cheese until well combined.

Assemble and Bake

Pour the filling into the prepared pie crust. Bake in the preheated oven for 30-35 minutes or until the quiche 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.

Pro Tips

For a twist, try adding crumbled feta cheese or sun-dried tomatoes to the filling for added flavor.

Make-Ahead Tips

Sunday mornings can be hectic, but you can prepare your Spinach Mushroom Quiche in advance. The filling can be prepared the day before and stored in the refrigerator. This allows the flavors to meld, creating a more robust taste. When ready to bake, simply combine the filling with the pie crust and bake as directed. That's what I often do—somehow, the quiche tastes even better the next day!

You can also freeze the quiche. To do this, bake it fully, allow it to cool, and then wrap it tightly in plastic wrap and foil. When you're ready to eat it, simply thaw it overnight in the fridge and reheat in the oven at 350°F (175°C) for about 20-25 minutes. This method preserves the texture and flavor beautifully, making it an ideal weeknight meal.

Serving Suggestions

Pair your Spinach Mushroom Quiche with a light salad dressed in lemon vinaigrette for a refreshing contrast. The acidity of the dressing complements the creaminess of the quiche perfectly. You might also consider serving it with crusty bread for a heartier meal, making it perfect for brunch or a family dinner.

For a flavorful twist, top your quiche with fresh herbs like chives or parsley before serving. This not only adds a pop of color but also enhances the overall flavor profile, brightening the earthy notes of the spinach and mushrooms. I love how an extra sprinkle can elevate the dish without requiring significant extra effort.
