Ingredients You’ll Need

All the ingredients in this Mushroom Puff Pastry Pot Pie Recipe come together to create that classic pot pie experience, with a vegan twist that’s creamy, rich, and just bursting with umami. Grab fresh mushrooms and make sure your puff pastry is thawed perfectly for the best results.

• Puff pastry sheet: Thaw it properly so it’s easy to handle but still cold enough to stay flaky when baked.
• Olive oil: A good quality oil brings out the earthiness of the mushrooms during sautéing.
• Yellow onion: Adds subtle sweetness and depth to the filling.
• Cremini mushrooms: Firm and hearty, great for texture and flavor.
• Oyster mushrooms: Their delicate flavor contrasts nicely with cremini, and their texture feels almost meaty.
• Carrots: Provide a touch of sweetness and color.
• Tomato paste: It gives a rich umami boost to the filling.
• Garlic cloves: Fresh garlic keeps the flavor bright and aromatic.
• Fresh thyme leaves: Classic herb for pot pies to add earthiness.
• Paprika: Gives a subtle warmth and color.
• Black pepper: Freshly ground for the best kick.
• Dry red wine (or water): Deglazing with wine adds complexity but water works fine too!
• Gold potatoes: Small diced, for hearty bite and creaminess.
• All-purpose flour: Helps thicken the filling nicely.
• Cashews (soaked): This is the secret to creamy vegan “sauce” without dairy.
• Vegetable broth: Adds flavor and thins the filling just right.
• Vegan Worcestershire sauce (optional): Adds a deeper umami punch if you have it.
• Low-sodium tamari or soy sauce: For that savory hit of saltiness.
• Frozen peas: Bright, sweet bursts of freshness near the end.
• Non-dairy milk: For brushing the puff pastry so it browns beautifully.

Variations

I love making this Mushroom Puff Pastry Pot Pie Recipe my own by swapping in different veggies or adjusting for what I have on hand—feel free to customize it to your heart’s content!

• Add nuts or seeds: For extra crunch, try sprinkling toasted walnuts or pumpkin seeds on the filling before topping with puff pastry—my kids actually love this texture contrast!
• Use other mushrooms: Cremini and oyster are my favorites, but shiitake or portobello work great too for different earthy tones.
• Make it gluten-free: Swap out regular flour for a gluten-free blend and use gluten-free puff pastry, and you’re good to go.
• Include fresh herbs: Rosemary or sage in place of thyme can bring new aroma and flavor profiles.

How to Make Mushroom Puff Pastry Pot Pie Recipe

Step 1: Sauté Your Vegetables to Perfection

Heat your olive oil in an oven-safe pan over medium-high heat and toss in the diced onion, mushrooms, and carrots. I like to let them brown lightly because that caramelization adds a ton of flavor you don’t want to miss. Stir occasionally and watch as the veggies soften up—this step takes about 7 minutes. Then, mix in the tomato paste and cook for another couple of minutes to deepen that savory character. Finally, add the garlic, thyme, paprika, and pepper, and stir just until fragrant—this usually takes about 30 seconds. Keep your nose tuned in here because that aroma signals you’re on the right track!

Step 2: Deglaze and Thicken Your Filling

Pour in the red wine to deglaze the pan, scraping up all those browned bits stuck to the bottom. If you’re skipping wine, water works just fine for this. Let it cook down until mostly evaporated—about 2 to 3 minutes. This concentrated flavor base really makes the filling special, in my opinion. Sprinkle the flour over the veggies, stir well, and cook for 1 minute to remove the raw flour taste and help thicken later.

Step 3: Blend and Simmer the Creamy Base

This is where the magic happens! Blend the soaked cashews, vegetable broth, Worcestershire (if using), and tamari until smooth and creamy. That cashew cream is a super easy way to get richness without dairy. Once blended, pour it into your pan along with the diced potatoes and stir well. Bring the mixture to a boil, then turn down the heat and let it simmer gently for 10-12 minutes. This softens the potatoes and lets everything thicken up nicely. Toss in the frozen peas at the end for a pop of color and sweetness before you take the filling off the heat.

Step 4: Assemble and Bake Your Pot Pie

If you’re not cooking in an oven-safe pan, transfer the filling to your chosen baking dish. Roll out your puff pastry if needed—it should be large enough to cover your dish with an inch or so overhanging. Lay the pastry over the filling, tuck under excess dough, and pinch to seal. Don’t forget to cut a few slits on top to let steam escape—that’s a small step that saves you from a soggy crust. Brush the pastry with non-dairy milk for a beautiful golden finish. Baking at 400°F for 25 to 30 minutes gives you that perfect crust and bubbly filling inside. Then, be patient and let it rest for about 10 minutes before slicing—it helps everything set so your first forkful doesn’t spill everywhere.

How to Serve Mushroom Puff Pastry Pot Pie Recipe

Garnishes

For garnishes, I keep it simple but fresh: a sprinkle of chopped parsley or snipped fresh thyme leaves brings brightness and a pop of color to the golden puff pastry. Sometimes I drizzle a little truffle oil over the filling before topping it for a luxurious touch—totally optional but worth trying if you love mushrooms!

Side Dishes

I like pairing this pot pie with a crisp green salad dressed lightly in lemon vinaigrette to balance the richness. Roasted Brussels sprouts or steamed green beans also make perfect sides, adding a fresh contrast and texture to every bite.

Creative Ways to Present

For special occasions, I’ve even made mini versions using muffin tins—rolling puff pastry and filling each cup with the mushroom mix to create adorable individual pot pies. They wow guests and are super fun to serve at gatherings or cozy dinners.

Make Ahead and Storage

Storing Leftovers

Leftovers store beautifully in an airtight container in the fridge for up to 5 days. I usually cover mine tightly with foil if leftover in the baking dish itself to help keep the crust from getting too soft.

Freezing

I’ve had great success freezing this pot pie either fully assembled or just the filling. Wrap the assembled pot pie tightly with plastic wrap and foil, then freeze for up to 2 months. When ready to eat, thaw overnight in the fridge and bake until warmed through and crispy again.

Reheating

To reheat, I prefer the oven or toaster oven to keep that crust crisp—just bake at 350°F until heated throughout, usually about 20 minutes. Microwaving is faster but can make your crust soggy, so I use it only when I’m in a rush.
