Gathering a handful of everyday ingredients is all it takes to create this show-stopping quiche. Each component plays a vital role, from the flaky tart crust that provides a sturdy base, to the fresh spinach and crimini mushrooms that bring garden-fresh flavors and delightful texture.

• Tart crust: Provides a crisp, buttery foundation that holds the filling perfectly.
• Butter: Adds richness and helps sauté the vegetables beautifully.
• Crimini mushrooms: Offer a juicy, earthy depth that elevates the quiche’s taste.
• Fresh spinach: Delivers a vibrant green color and mild, slightly sweet flavor.
• Onion: Sweated down to subtle sweetness, it creates a flavorful base.
• Eggs: The key to a luscious, silky custard that binds everything together.
• Whole milk: Adds creaminess and lightness to the filling.
• Heavy cream: Boosts richness for that melt-in-your-mouth texture.
• Gruyère cheese: Introduces a salty, nutty layer that complements the vegetables perfectly.

How to Make Spinach Mushroom Quiche

Step 1: Prep and Pre-Bake the Tart Crust

Start by preheating your oven to 375°F (190°C). Roll out your tart crust dough and gently fit it into a pie dish. To ensure the crust cooks evenly and stays crisp when filled, pre-bake it for about 10 minutes until it just begins to turn a lovely golden color. This step creates the perfect base for our flavorful filling.

Step 2: Sauté the Vegetables

While the crust is cooling, melt butter in a skillet over medium heat. Toss in diced onions and cook them gently until translucent and sweet. Next, add the crimini mushrooms and sauté until they soften and release their earthy flavors. Finally, stir in fresh spinach, cooking until just wilted. This medley of vegetables forms a vibrant, tender filling that’s bursting with flavor.

Step 3: Prepare the Custard Mixture

In a mixing bowl, whisk together eggs, whole milk, and heavy cream until smooth. Season the custard base with salt, pepper, and a pinch of cayenne if you want a subtle spicy kick. This gooey mixture will gently bake into a delicate, creamy center, so take your time to combine it thoroughly.

Step 4: Combine Filling and Pour into Crust

Add the sautéed vegetables to the custard, then fold in shredded Gruyère cheese. This cheese brings a luscious depth and a touch of saltiness that perfectly balances the greens and mushrooms. Pour this rich filling into your pre-baked tart shell, making sure to spread it evenly for uniform baking.

Step 5: Bake Until Golden and Set

Pop the quiche into your oven and bake for about 60 minutes or until the custard is fully set and the top is beautifully golden. Once baked, let the quiche cool slightly before slicing, allowing the filling to firm up so each piece holds together beautifully without being dry.

How to Serve Spinach Mushroom Quiche

Garnishes

Adding fresh garnishes enhances the look and flavor of your Spinach Mushroom Quiche. Sprinkle some freshly chopped chives or parsley on top to bring a pop of color and fresh herbal brightness. A light drizzle of good-quality olive oil or a scattering of toasted pine nuts can also add texture and richness.

Side Dishes

This quiche pairs wonderfully with a crisp green salad tossed in a tangy vinaigrette, which cuts through the richness of the custard. Roasted cherry tomatoes or a simple cucumber salad also offer refreshing contrast. For a heartier meal, creamy mashed potatoes or roasted baby potatoes make great companions.

Creative Ways to Present

For a brunch spread, consider slicing the Spinach Mushroom Quiche into small squares and serving them as elegant finger food. You can also present it alongside assorted pickles and charcuterie for a festive appetizer board. Serving warm or at room temperature ensures it remains accessible and flavorful for any occasion.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover any leftover quiche tightly with plastic wrap or store in an airtight container. It will keep well in the refrigerator for up to 3 days, making it perfect for quick lunches or light dinners throughout the week.

Freezing

Spinach Mushroom Quiche freezes beautifully. Wrap individual slices in plastic wrap and place them in a freezer-safe bag. They can be stored for up to 2 months—ideal for batch cooking and saving time on busy days.

Reheating

To enjoy leftovers, reheat slices gently in a preheated oven at 350°F (175°C) for about 15-20 minutes to retain the crisp crust and creamy filling. Avoid microwaving if possible, as it can make the crust soggy and the texture less appealing.

FAQs

Can I use frozen spinach instead of fresh?

Absolutely! Just be sure to thaw and drain the spinach thoroughly to remove excess water; otherwise, the filling might turn out watery.

What if I don’t have Gruyère cheese?

You can substitute with Swiss cheese or even a mild cheddar, but Gruyère offers a unique nutty flavor that really makes this quiche special.

Is it possible to make the tart crust from scratch?

Yes, making your own crust adds a wonderful homemade touch. Use a simple butter-based pastry dough, and try to chill it well for easy rolling and a flakier texture.

Can this quiche be served cold?

While it’s best warm, Spinach Mushroom Quiche also tastes delightful cold, especially on picnics or as a light snack.

How can I add extra protein?

Feel free to add cooked bacon, ham, or even smoked salmon bits to the filling for a more substantial meal without overpowering the vegetables.
