The Star Ingredients of Spinach Mushroom Quiche

Let’s break down what you’ll need to create the magic:

1. Refrigerated 9-inch Pie Crust

Short on time? A store-bought pie crust works perfectly and saves you tons of prep time. If you’re feeling adventurous, you can make a homemade buttery crust, but trust me, refrigerated crusts deliver fantastic results for Spinach Mushroom Quiche.

2. Olive Oil

Just a tablespoon is enough to sauté your mushrooms and spinach. Olive oil adds a lovely, subtle flavor that enhances the earthy notes of the veggies.

3. Baby Bella Mushrooms

These baby portobello mushrooms bring a meaty texture and deep, savory flavor. Slice them thin for quicker cooking and better distribution throughout your quiche.

4. Fresh Spinach

Chopped fresh spinach adds vibrant color and a boost of nutrients. Wilt it slightly before adding it to the pie crust to prevent excess moisture in your Spinach Mushroom Quiche.

5. Large Eggs

Eggs are the backbone of any quiche. They create the rich, custardy filling that holds everything together.

6. Milk

Choose 2% or whole milk for a perfect balance of creaminess without being overly rich. You can substitute half-and-half for an even silkier texture.

7. Seasonings

Simple yet essential: kosher salt, black pepper, and garlic powder. These bring out the natural flavors of the vegetables and create a deeply satisfying taste.

8. Shredded Cheddar Cheese

Cheddar adds just the right amount of sharpness and meltiness. Feel free to mix in other cheeses like Swiss, Gruyère, or mozzarella for extra flair.

How to Make Spinach Mushroom Quiche: Step-by-Step

Ready to create the best Spinach Mushroom Quiche ever? Let’s walk through it:

Step 1: Preheat the Oven

Set your oven to 375°F so it’s perfectly hot and ready when your quiche is assembled.

Step 2: Prepare the Pie Crust

Roll out your 9-inch pie crust and gently place it into a pie pan. Press down to fit the bottom and sides snugly. If you like, flute the edges for a decorative touch.

Pro Tip: You can blind-bake the crust for about 8 minutes if you want an extra crisp bottom, but it’s optional!

Step 3: Sauté the Mushrooms

In a skillet over medium heat, warm your tablespoon of olive oil. Add the sliced mushrooms and cook for about 5 minutes until they are tender and have released most of their moisture.

Step 4: Wilt the Spinach

Add the chopped spinach right into the same skillet. Stir gently until it’s just wilted—this should take about 2 minutes. Remove from heat and let cool slightly.

Step 5: Whisk the Eggs

In a large bowl, whisk together your 4 large eggs, 1 cup of milk, ½ teaspoon kosher salt, ¼ teaspoon black pepper, and ½ teaspoon garlic powder. Whisk until smooth and fully combined.

Step 6: Assemble the Quiche

Layer the cooked mushrooms and spinach evenly over the bottom of your prepared crust. Sprinkle the shredded cheddar cheese generously over the vegetables.

Then, slowly pour the egg mixture over the top. Gently tap the pie plate on the counter to eliminate any air bubbles and evenly distribute the filling.

Step 7: Bake

Bake your Spinach Mushroom Quiche for 40 to 45 minutes, or until the center is set and the top is lightly golden.

Step 8: Cool and Slice

Allow the quiche to cool for 5 to 10 minutes. Then slice into 8 delicious wedges and serve!

Tips for the Best Spinach Mushroom Quiche

• Don’t overfill the crust. The egg mixture should come just below the edge to prevent spillage.
• Use fresh ingredients for the brightest flavor.
• Drain excess moisture from the mushrooms and spinach to avoid a soggy bottom.
• Let the quiche rest after baking. This helps it set up and makes slicing cleaner.
• Play with cheese blends: Cheddar + mozzarella, or Swiss + Gruyère, can elevate your quiche.
