When I first made this quiche, I was unsure if the flavors would meld well together. I was pleasantly surprised to find that the spinach and mushrooms created a vibrant, earthy taste that was both satisfying and delicious. The magic lies in sautéing the mushrooms first, which allows their natural flavors to deepen and become even more robust.

I've learned that letting the quiche sit for a few minutes after baking lets the filling set, making slicing easier while keeping the texture wonderfully creamy. Also, feel free to add a pinch of your favorite herbs for an extra layer of flavor!

Choosing the Right Ingredients

The success of your Sunday Spinach Mushroom Quiche hinges significantly on the quality of your ingredients. Fresh spinach is not just a nutritious addition; it also adds a vibrant color and flavor that frozen spinach simply cannot match. Before using, select bright, vibrant leaves, and be sure to wash them thoroughly to remove any grit. Similarly, when it comes to mushrooms, opt for cremini or button mushrooms for a more robust flavor. If you want a deeper taste, try adding a mix of wild mushrooms.

Using a high-fat cream, such as heavy cream, is essential for creating that rich, creamy filling that defines this quiche. If you're concerned about calories, half-and-half can work in a pinch, but expect a slightly less indulgent texture. For cheese, I recommend using a mix of cheddar and mozzarella; the sharpness of cheddar balances beautifully with the creamy mozzarella and adds depth to the flavor profile.

Perfecting the Cooking Technique

When baking your quiche, it’s crucial to keep an eye on the filling while it cooks. You want it to be set but still jiggly in the center when you pull it out of the oven; an overcooked quiche can lead to a dry texture. The edges should be golden-brown, giving a visual cue that it's done. Keeping the oven temperature constant at 375°F (190°C) ensures even cooking throughout the dish, so avoid opening the oven door too often while baking.

Allowing the quiche to cool for at least 10 minutes before slicing is another key step that shouldn't be overlooked; this resting time helps firm up the filling, allowing for cleaner slices. You can also customize the spices in this recipe, adding herbs like thyme or basil to further enhance the flavor. I often experiment with these to give my quiche a unique touch that reflects the season or my mood.

1 cup heavy cream

Instructions

Follow these easy steps to prepare your Sunday Spinach Mushroom Quiche:

Prepare the Crust

Preheat your oven to 375°F (190°C). Place the pre-made pie crust in a 9-inch pie dish and prick the bottom with a fork. Bake for 10 minutes until lightly golden.

Sauté Vegetables

In a skillet, heat the olive oil over medium heat. Add the sliced mushrooms and sauté until browned, about 5-7 minutes. Add the chopped spinach and cook until wilted, about 2-3 minutes. Remove from heat and let cool slightly.

Prepare Filling

In a mixing bowl, whisk together the eggs, heavy cream, salt, pepper, and nutmeg. Stir in the sautéed spinach and mushrooms, along with the shredded cheese.

Combine and Bake

Pour the filling into the pre-baked pie crust. Bake in the preheated oven for 30-35 minutes or until the filling is set and the top is golden. Allow it to cool for a few minutes before slicing.

Enjoy your quiche warm, or let it cool and serve at room temperature!

Pro Tips

For a gluten-free option, use a gluten-free pie crust. Feel free to add bacon or sausage for a heartier dish!

Make-Ahead Tips

One of the great features of this quiche is its make-ahead capability. You can prepare the filling and assemble the quiche in advance, then store it in the refrigerator for up to 24 hours before baking. This is especially useful for busy mornings when you want to enjoy a leisurely brunch without the last-minute rush. Just be sure to cover it tightly to avoid any flavor contamination.

If you're looking to make it even earlier, consider baking the quiche ahead of time. Once fully cooled, store it in an airtight container in the refrigerator for up to three days. It also freezes well; to freeze, wrap tightly in plastic wrap and then foil after cooling completely. Thaw in the refrigerator overnight and reheat in a 350°F (175°C) oven until warmed through for an effortless meal later.

Serving Suggestions

Serving your spinach mushroom quiche can be as creative as you like! While it’s delicious on its own, adding a light arugula salad dressed with lemon vinaigrette can elevate the meal, offering a nice contrast with its peppery flavor. I often serve it with a side of roasted cherry tomatoes, which add a burst of sweetness and color to the plate.

For a more casual gathering, slice the quiche into smaller pieces for an easy finger-food option. You can even customize each portion with different toppings like fresh herbs or a dollop of sour cream. This allows your guests to mix and match flavors according to their preferences, making it an interactive dining experience.
