Mushroom & Leek Pie Ingredients
For the Pie Crust
• Single-Crust Pie Dough – A flaky base that holds your savory filling; feel free to use homemade or store-bought for convenience.
For the Filling
• Mushrooms (Chanterelle, Baby Portobello, Oyster) – These add a deep umami flavor; you can substitute with your preferred mushroom variety if needed.
• Butter (3 tablespoons total) – Provides richness to the filling; olive oil makes a great vegan alternative.
• Leek (1 medium, white part only) – Offers a subtle sweetness that enhances the flavor; save the green tops for garnishing or other recipes.
• Salt (1/2 teaspoon) – Essential to bring out all those delicious flavors; adjust depending on dietary needs.
• Pepper (1/4 teaspoon) – A hint of spice that can be omitted for milder tastes.
• Cheddar Cheese (1 cup, shredded) – Adds creamy richness to the pie; swap for mozzarella or a dairy-free option if lactose-sensitive.
• Large Eggs (4) – Binds all ingredients together; flax eggs work as a vegan substitute if desired.
• Heavy Whipping Cream (3 tablespoons) – Contributes to the custardy filling; try a non-dairy cream for a lighter take.
• Minced Fresh Parsley (optional) – A fresh garnish that brightens the pie; chives can be used alternatively or omitted entirely.

Step‑by‑Step Instructions for Mushroom & Leek Pie
Step 1: Prepare the Pie Dough
Roll out your single-crust pie dough on a floured surface to about 1/8-inch thickness. Carefully fit the dough into a 9-inch pie plate, trimming any excess. Flute the edges for a decorative touch and chill in the refrigerator while you prepare the filling, ensuring it maintains its shape during baking.
Step 2: Cook the Leek
In a skillet over medium heat, melt 1 tablespoon of butter. Add the sliced white part of the leek and sauté for 2-3 minutes, until tender and translucent. Once cooked, set the leeks aside to cool slightly, allowing their delicate sweetness to enhance the flavors of your Mushroom & Leek Pie.
Step 3: Sauté the Mushrooms
Using the same skillet, add the remaining butter and heat over medium-high. Introduce your choice of mushrooms, sautéing them for 4-6 minutes until they are tender and their moisture has evaporated. Combine the cooked leeks with the mushrooms, seasoning with salt and pepper, then let the mixture cool for a moment before proceeding.
Step 4: Assemble the Filling
Preheat your oven to 375°F (190°C) while you layer the filling. Spread half of the shredded cheddar cheese evenly on the bottom of the chilled crust. Next, spoon the sautéed mushroom and leek mixture over the cheese, and top with the remaining cheese for a rich, melty finish.
Step 5: Prepare Egg Mixture
In a mixing bowl, whisk together the four eggs and heavy whipping cream until well combined. Pour this custardy mixture slowly over the pie filling, ensuring even distribution for a smooth texture in your Mushroom & Leek Pie.
Step 6: Bake
Place the assembled pie in the preheated oven and bake for 30-35 minutes, or until the filling is set and the top is lightly golden. To check for doneness, insert a knife into the center; it should come out clean. This ensures your delicious Mushroom & Leek Pie is ready to serve.
Step 7: Serve
Once baked, remove the pie from the oven and allow it to cool for a few minutes before slicing. The filling will firm up slightly as it cools. Garnish with fresh minced parsley if desired, adding a pop of color and flavor to your inviting Mushroom & Leek Pie.

Make Ahead Options
These Mushroom & Leek Pies are perfect for busy home cooks who want to save time without sacrificing flavor! You can prepare the pie crust and filling up to 24 hours in advance. Simply make the crust, fit it into your pie plate, and refrigerate. For the filling, sauté the mushrooms and leeks as directed, then let them cool and store in an airtight container in the fridge. When you’re ready to bake, simply layer the filling in the chilled crust, pour the egg mixture over it, and bake as instructed. This approach ensures that your pie remains just as delicious and fresh, while allowing for a seamless and stress-free meal prep experience!
How to Store and Freeze Mushroom & Leek Pie
