Heavy Cream: This adds a luxurious texture; feel free to substitute with half-and-half if desired.

How to Make Mushroom and Leek Quiche
Start by preheating your oven to 375°F (190°C). This sets the stage for a perfectly baked quiche. Prepare your pie crust by rolling it out into a 9-inch pie pan, pressing it firmly against the sides.
Sauté the Vegetables: In a skillet over medium heat, melt some butter until it sizzles invitingly. Add chopped leeks and sliced mushrooms, sautéing until they’re tender and fragrant—about 5-7 minutes should do it.
Prepare the Egg Mixture: In a mixing bowl, whisk together eggs, heavy cream, salt, and pepper until combined smoothly. The mixture should be light yet creamy—a feast for both eyes and taste buds.
Add Cheese and Veggies: Stir in grated cheese of choice along with the sautéed mushroom-leek combo into your egg mixture. This is where magic happens!
Fill the Pie Crust: Pour this heavenly mixture into your prepared pie crust evenly. Don’t worry about spills—life’s messy sometimes!
Bake Until Set: Slide your quiche into the preheated oven and bake for about 30-35 minutes until it’s puffed up like a little soufflé and golden brown on top. The aroma will be irresistible!
With each step infused with love (and maybe a dash of chaos), you’ll create a Mushroom and Leek Quiche that’s not only scrumptious but also an experience worth sharing!
Serve warm or at room temperature for brunches or dinner parties—trust me, it’s going to be quite the hit! Enjoy every delicious bite while basking in compliments from family and friends who won’t believe you whipped up such culinary magic.
