Cheesy spinach and mushroom quiche is made easy by using a frozen pie crust, so it's perfect for a busy weeknight or a lazy weekend. It's plump full of mushrooms, spinach, and a creamy filling made with cheddar cheese. Enjoy it for breakfast, brunch, or serve with a side salad for lunch or dinner.

I used to think of quiche as a splurge food. Like, it was this super fancy thing that I should only eat once or twice a year. I don't know when I changed my outlook, but I no longer subscribe to that thinking. Quiche is one of the most delicious foods (I said it), and frankly, we should eat it whenever we have the chance. "Life is short, eat quiche" is my new motto.

One of the best things about this spinach and mushroom quiche recipe is that it's super simple to make. I use frozen pie crust, so other than taking a few minutes to cook the veggies and beat your egg mixture, you simply let your quiche do its thing in the oven while you tend to more important things.

The result is a creamy, savory, veggie-packed quiche with just a hint of garlic and a buttery and flaky crust. It's a stunner of a dish, and one that can be eaten for breakfast, brunch, or served with a side salad for lunch or dinner.

Ingredients Needed

• Olive oil
• Cremini or button mushrooms
• Garlic, salt & pepper
• Fresh baby spinach
• Frozen pie crust
• Cheddar cheese
• Eggs
• Half-and-half

Step-By-Step Instructions

Preheat oven to 400 degrees F.

Heat oil in a large skillet over medium heat. When oil is hot, add sliced mushrooms. Cook, stirring occasionally, until the mushrooms are tender, about 5 minutes.

Add garlic and cook for an additional minute. Add spinach and cook, tossing continuously, until wilted, about 2 minutes. Remove from heat.

Press thawed pie crust into a deep, 9-inch tart pan with a removable bottom (or a deep-dish pie pan). Transfer spinach and mushroom mixture into crust and top with half of the cheddar cheese.

In a large bowl, whisk eggs, half-and-half, salt, and pepper. Pour egg mixture into the crust and top with the remaining cheese.

Place the pan on a rimmed baking sheet. Loosely cover the pan with aluminum foil and bake for 40 minutes. Remove the foil and continue baking until the quiche is set and the crust is golden brown, another 10 minutes.

Let the quiche rest for 10 minutes before serving.

Frequently Asked Questions

Can I use frozen spinach? Yes, but make sure you squeeze all of the water out of it before using.

What's the difference between quiche and frittata? While both are essentially baked egg dishes, a frittata is similar to an omelet in that it simply contains eggs and whatever veggies, protein, etc. you add to it. Quiche, on the other hand, is more of a baked egg custard, as it contains milk or half-and-half, and therefore has a creamy, custard-like consistency.

Can I freeze this quiche? Yes! Quiche is easy to freeze. I recommend wrapping each slice individually in aluminum foil and then placing the slices in a freezer-safe bag.

How do I reheat my frozen quiche? The best way to reheat this quiche is to place your frozen slice(s) into a 350 degree F oven for around 30 minutes. You can microwave your quiche, but the crust will become less flaky.

Can I use different vegetables and/or add meat? Yes! This recipe is very versatile, so you can substitute your favorite vegetable or protein.
