What Are Spinach and Mushroom Quiche?

Dating back to the medieval German cuisine, quiches evolved from savory tarts into the beloved French dish we know today. In its essence, a quiche consists of a pastry crust filled with a custard mixture of eggs and milk, enriched with a variety of fillings. My Spinach and Mushroom Quiche Recipe is a perfect embodiment of this classic dish, filled with the delicate flavors of sautéed mushrooms, fresh spinach, and creamy cheese.

The combination of the earthy mushrooms with the vibrant green spinach offers a delightful contrast in taste, while the creamy, custardy filling provides a luscious texture that melts in your mouth.

Ingredients for Spinach and Mushroom Quiche

• 1 3/4 cups chopped mushrooms: Button or cremini mushrooms work great. Fresh is always best for flavor!
• 2/3 cup fresh spinach (chopped): Baby spinach is a fantastic choice for its tenderness and flavor.
• 2 tbsp olive oil: Use high-quality extra-virgin olive oil for a rich taste.
• 1 tsp kosher salt (divided): Helps to enhance all the flavors in the dish.
• 2/3 cup thinly-sliced leek (or onion): Leeks add sweetness, but yellow onions can be substituted in a pinch.
• 4 large eggs: Fresh, organic eggs yield the best flavor.
• 1 1/3 cups cream or milk: Use heavy cream for a rich quiche or whole milk for a lighter version.
• 2/3 cup packed grated cheese (Gruyère, Swiss, or a mild cheddar): Gruyère provides a nutty flavor that pairs beautifully, but feel free to use your favorite cheese.
• Single-crust pie dough: You can use homemade or store-bought; just ensure it’s chilled before use.

Note: For the pie dough, I highly recommend using a high-quality brand like Pillsbury if you’re opting for store-bought. If you prefer homemade, ensure your butter is at room temperature for easy mixing.

Step-by-Step Instructions

1. Prep the Vegetables

• Preheat your oven to 425°F.
• Toss the mushrooms, spinach, and leeks with olive oil and 1/2 tsp kosher salt on a baking sheet.
• Roast for 12-15 minutes, flipping halfway through until browned.
• Transfer to a large bowl and allow to cool. Wipe the baking sheet clean and return it to the lower third rack in the oven to keep warm.

2. Prepare the Crust

• Place the pie dough in a 9-inch pie dish, crimping the edges as desired.
• Freeze the pie crust for 10-15 minutes until firm. This helps prevent sogginess!

3. Make the Filling

• In the bowl with the roasted vegetables, add the eggs, cream (or milk), cheese, and the remaining 1/2 tsp kosher salt.
• Whisk until the mixture is frothy and well combined.

4. Bake the Quiche

• Place the pie crust on the preheated baking sheet.
• Pour the filling into the crust and bake for 15 minutes at 425°F.
• After that, reduce the oven temperature to 300°F and continue baking for an additional 20-25 minutes, until the center is mostly set but still slightly wobbly, reaching 150°F internally.

5. Cool and Serve

• Let the quiche rest for 20 minutes at room temperature to set before slicing. This resting time helps to complete the cooking process and makes slicing easier.

Chef’s Tips:

• Don’t skip the cooling step, as it helps the quiche to firm up perfectly.
• Keep an eye on the filling during the last few minutes. Every oven is different!

Expert Tips & Tricks

1. Ingredient Quality: Choose fresh vegetables and high-quality cheese for the best flavor.

2. Cool Before Slicing: Letting the quiche cool allows it to set, preventing a watery filling.

3. Make-Ahead: You can prepare the filling a day in advance and assemble the quiche just before baking.

4. Storage: Unbaked quiche can be frozen. Wrap tightly in plastic wrap and foil for up to three months. Bake straight from the freezer, adding an extra 10-15 minutes to the cooking time.

5. Common Mistakes: Avoid overcooking! A slightly jiggly center means your quiche is perfectly cooked and will continue to set as it cools.

6. Adapt for Seasons: Swap out the spinach and mushrooms for seasonal veggies like asparagus in spring or zucchini in summer.

Serving Suggestions

A slice of my Spinach and Mushroom Quiche pairs beautifully with a crisp green salad dressed in a tangy vinaigrette. For an extra touch, serve it with a side of fresh fruit for color and sweetness.

For brunch gatherings, consider presenting it with fresh pastries, a fruit platter, or a fluffy frittata. This quiche is not only a crowd-pleaser but also offers a visual feast!

Variations & Substitutions

• Crust Alternatives: Try a sweet potato crust for a gluten-free option that adds a touch of sweetness.
