A really good mushroom pie comes down to one thing: a deep, savory gravy packed with earthy mushrooms, all wrapped in a golden, flaky pastry crust.
This one uses a mix of chestnut, portobello, and dried porcini mushrooms simmered down with onion, garlic, and a splash of white wine until the filling is rich enough to eat with a spoon.
It is a proper British-style pie, meaning the filling sits between a bottom and top layer of pastry, so every bite gets that satisfying crunch.

I first made this mushroom pie after a farmers market haul left me with way more mushrooms than I knew what to do with.
It has since turned into one of my favorite ways to make a meatless dinner feel like a proper Sunday roast, alongside my Steak and Mushroom Pie Recipe for the meat eaters in the house.
Why You’ll Love This Mushroom Pie Recipe
This pie takes humble mushrooms and turns them into something that feels genuinely special.
The filling is rich, glossy, and deeply savory, thanks to a mix of fresh and dried mushrooms cooked low and slow.
It is a fantastic make-ahead meal too, since the filling can be cooked a day or two in advance.
And because it is fully vegetarian, it works as a main dish for meat eaters and non-meat eaters alike, no separate cooking required.
- Rich, meaty texture from a mix of mushroom varieties, no meat required
- Deep flavor built from browning, deglazing, and a long simmer
- Make-ahead friendly filling that only gets better overnight
- Flaky, golden double crust that holds its shape when sliced
- Easily adapted to vegan with a few simple swaps

Ingredients
Most of what you need for this mushroom pie recipe is likely already in your kitchen, aside from the dried porcini, which is worth seeking out for the flavor boost it gives the gravy.

Kitchen Equipment Needed
Nothing here is overly specialized, though a good heavy-bottomed skillet makes a real difference when it comes to browning the mushrooms properly.
- Large skillet or enameled cast iron skillet
- 9-inch ceramic pie dish
- Rolling pin
- Mixing bowls
- Pastry brush
- Sharp knife and cutting board
The same skillet gets a lot of use in my Vegetable Pot Pie Recipe, so it is a good one to have on hand if you cook a lot of pies.
Recommended Products for This Recipe
These are a few products I personally rely on when I make this mushroom pie, based on what has actually made a difference in my own kitchen.
1. Dried Porcini Mushrooms
These are the secret to making a vegetarian pie taste as savory as a meat one.
A small handful, along with the soaking liquid, adds a deep, almost beefy flavor to the gravy that fresh mushrooms alone cannot replicate.
2. Ceramic Pie Dish
A sturdy ceramic pie dish holds heat evenly, which means the bottom crust actually crisps up instead of turning soggy.
It also looks great going straight from the oven to the table.
3. Enameled Cast Iron Skillet
I use this for browning the mushrooms in batches, and the heavy base keeps the heat steady so the mushrooms actually caramelize instead of steaming.
It is also just as useful for soups, stews, and pretty much everything else.
4. French Rolling Pin
A tapered French rolling pin gives you a lot more control when rolling out pastry evenly, which matters for a neat, even bake.
It is a small upgrade that makes pastry work noticeably less fiddly.

Step-by-Step Instructions: How to Make Mushroom Pie
1. Soak the Dried Porcini and Prep the Vegetables
- Place the dried porcini mushrooms in a small heatproof bowl and pour over 250ml of hot water.
- Let them soak for 15 to 20 minutes, until softened, then lift them out and roughly chop.
- Strain the soaking liquid through a fine sieve or a piece of paper towel to remove any grit, and set the liquid aside. This will go into the gravy later.
- While the porcini soak, finely dice the onions and mince the garlic.
- Clean the fresh mushrooms with a damp cloth or paper towel rather than rinsing them under water, since mushrooms soak up moisture easily and this can make them steam instead of brown.
- Slice the fresh mushrooms into even pieces, about a quarter inch thick.
2. Brown the Mushrooms in Batches
- Heat 1 tablespoon of butter and the olive oil in a large skillet over medium-high heat.
- Add a third of the sliced mushrooms in a single layer, without crowding the pan, and let them cook undisturbed for 2 to 3 minutes.
- Stir and continue cooking until deeply golden, about 5 minutes total, then transfer to a plate.
- Repeat with the remaining mushrooms in two more batches, adding a little more butter as needed. Browning in batches is what gives the filling its rich, deep flavor, so try not to skip this step.
3. Cook the Onions and Garlic
- Reduce the heat to medium and add the remaining butter to the same skillet.
- Add the diced onions and cook for 6 to 8 minutes, stirring occasionally, until soft and lightly golden.
- Stir in the minced garlic and chopped porcini mushrooms, and cook for 1 more minute until fragrant.
4. Build the Gravy
- Sprinkle the flour over the onion mixture and stir constantly for 1 minute to cook off the raw flour taste.
- Slowly pour in the white wine, scraping up any browned bits from the bottom of the pan.
- Add the vegetable stock and the reserved porcini soaking liquid, stirring well to avoid lumps.
- Return the browned mushrooms to the pan along with the thyme leaves and bay leaf.
- Bring the mixture to a gentle simmer and cook, stirring occasionally, for 10 to 12 minutes, until thickened enough to coat the back of a spoon.
5. Finish and Cool the Filling
- Stir in the Dijon mustard, vegetarian Worcestershire sauce, and heavy cream.
- Simmer for another 2 to 3 minutes, then season generously with salt and pepper to taste.
- Remove the bay leaf and discard it.
- Transfer the filling to a shallow dish and let it cool to room temperature, then refrigerate for at least 1 hour, or overnight. A cold filling is key to preventing a soggy bottom crust.
6. Assemble the Pie
- Preheat your oven to 200°C (400°F).
- Roll out one sheet of pastry and use it to line the bottom and sides of your 9-inch pie dish, leaving a slight overhang.
- Spoon the cooled mushroom filling into the pastry-lined dish, spreading it into an even layer.
- Brush the pastry edge with a little of the beaten egg.
- Roll out the second sheet of pastry and lay it over the filling, pressing the edges together firmly to seal.
- Trim off any excess pastry and crimp the edges with a fork or your fingers.
- Cut two or three small slits in the top crust to let steam escape, then brush the entire top with the remaining beaten egg.
7. Bake Until Golden
- Place the pie on a baking sheet to catch any drips, and bake for 40 to 45 minutes, until the pastry is deeply golden brown.
- If the edges start to brown too quickly, loosely cover them with foil for the remaining bake time.
- Let the pie rest for 10 minutes before slicing, so the filling has time to set.
This same low-and-slow gravy technique is what makes my Mushroom Risotto Recipe so creamy too.
Tips for The Best Mushroom Pie
A few small details make the difference between a good mushroom pie and a great one.
- Do not skip browning the mushrooms in batches, since overcrowding the pan causes them to steam rather than caramelize.
- Make sure the filling is completely cold before assembling the pie, or the pastry will not hold its shape while baking.
- Use a mix of mushroom varieties for the best texture and flavor, rather than relying on just one type.
- Blind baking is not necessary here as long as the filling is cold and the oven is hot enough to crisp the base.
- Keep the pastry cold right up until it goes in the oven for the flakiest results.

Serving Suggestions
This pie is hearty enough to serve on its own, but a few simple sides round out the meal nicely.
I like to keep things classic, since the pie itself already carries a lot of flavor.
- Steamed green beans or garlicky sauteed spinach
- Creamy mashed potatoes for extra comfort
- A simple side salad with a sharp vinaigrette to cut through the richness
- Buttered peas, for a classic British pub-style plate
- A drizzle of extra gravy on the side, if you have any leftover
For a heartier plate, try pairing it with Creamy Mashed Potatoes.
Variations of Mushroom Pie
Once you have the base recipe down, it is easy to adapt this pie to whatever you have on hand or whatever diet you are cooking for.
- Vegan mushroom pie: swap the butter for a plant-based alternative, use coconut cream or cashew cream instead of heavy cream, and use a vegan puff pastry.
- Puff pastry topped: use puff pastry only for the top crust and skip the bottom crust for a lighter, more casserole-like texture.
- Wild mushroom version: use a mix of chanterelles, shiitake, and oyster mushrooms in place of the chestnut and portobello mushrooms.
- Ale-based gravy: replace the white wine with a dark stout for a deeper, maltier flavor.
- Individual pies: divide the filling and pastry among small ramekins for personal-sized pies with a shorter bake time.

Storage and Reheating
This mushroom pie keeps well, which makes it a great option for meal prep or leftovers.
- Store leftover pie, covered, in the refrigerator for up to 3 days.
- Reheat individual slices in a 180°C (350°F) oven for 15 to 20 minutes, until warmed through and the pastry has re-crisped.
- Avoid microwaving if possible, since it will make the pastry soft and chewy rather than flaky.
- To freeze, wrap the fully baked and cooled pie tightly and freeze for up to 2 months.
- Thaw overnight in the refrigerator before reheating in the oven.
The same overnight-chill trick works well for my Spinach and Mushroom Casserole Recipe too.
