How to Make Spinach & Mushroom Quiche

Step 1: Preheat and Prep the Pie Pan

1. Preheat your oven to 375°F (190°C).
2. Coat a 9-inch pie pan with cooking spray and set aside.

Step 2: Cook the Vegetables

1. Heat the olive oil in a large nonstick skillet over medium-high heat. Swirl to coat the pan evenly.
2. Add the mushrooms and cook, stirring occasionally, until browned and tender, about 8 minutes.
3. Add the onion and garlic, cooking and stirring until softened, about 5 minutes.
4. Toss in the chopped spinach and cook until wilted, about 1–2 minutes. Remove from heat and let cool slightly.

Step 3: Whisk the Egg Mixture

1. In a medium bowl, whisk together the eggs, milk, half-and-half, Dijon mustard, thyme, salt, and pepper.
2. Fold in the sautéed vegetable mixture and shredded Gruyère cheese.

Step 4: Assemble and Bake

1. Pour the egg mixture into the prepared pie pan, spreading it evenly.
2. Bake in the preheated oven for about 30 minutes, or until the quiche is set and golden brown on top.
3. Let the quiche cool for 10 minutes before slicing.
4. Garnish with fresh thyme and serve warm.

Tips for the Perfect Spinach & Mushroom Quiche

1. Choose the Right Mushrooms

Using a mix of wild mushrooms like cremini, shiitake, or oyster adds depth to the flavor. Button mushrooms work well if you’re looking for an affordable option.

2. Use Fresh Ingredients

Fresh spinach and sweet onions enhance the overall taste and texture of the quiche. Avoid frozen spinach, as it can make the quiche watery.

3. Don’t Overcook

Keep an eye on the baking time. Overcooking can result in a rubbery texture instead of a creamy custard.

4. Experiment with Cheeses

Gruyère is classic, but you can also use cheddar, feta, or a mix of cheeses for a unique flavor.
