Ingredients You’ll Need

This Mushroom Pot Pie with Puff Pastry Recipe uses simple, fresh ingredients you can find at almost any grocery store. The mushrooms and herbs create an amazing umami base, while the puff pastry adds that irresistible crunch. Picking the right mushrooms and using soaked cashews really make a difference in the creamy texture here.

• Puff pastry sheet: Make sure to thaw it properly so it’s easy to work with and bakes up beautifully golden.
• Olive oil: Use a good quality extra virgin olive oil to sauté your veggies and bring out their natural flavors.
• Yellow onion: A fine dice helps it melt seamlessly into the filling.
• Cremini mushrooms: Quartered for hearty bites and a nice meaty texture.
• Oyster mushrooms: Roughly chopped to add subtle texture contrasts and mild sweetness.
• Carrots: Adds a bit of sweetness and color.
• Tomato paste: Boosts richness and depth in your filling.
• Garlic cloves: Fresh and minced to infuse the filling with that warm, aromatic punch.
• Fresh thyme leaves: The herb that just makes everything taste like comfort.
• Paprika and black pepper: Adds subtle warmth and spice.
• Dry red wine (or water): I love using wine to deglaze the pan—it adds such a beautiful complexity.
• Gold potatoes: Small diced for creamy chunks inside the filling.
• All-purpose flour: Helps thicken the delicious filling.
• Cashews: Soaked for a velvety, dairy-free creaminess.
• Vegetable broth: The flavorful liquid base that keeps it rich and savory.
• Vegan Worcestershire sauce (optional): I add this for some extra savory depth, but you can skip it if you want.
• Low-sodium tamari or soy sauce: A splash of umami magic.
• Frozen peas: Tossed in right before finishing for a pop of color and sweetness.
• Non-dairy milk: For brushing the puff pastry, it gives a perfect golden finish.

Variations

I love how versatile this Mushroom Pot Pie with Puff Pastry Recipe is. Sometimes I switch things up to match whatever veggies I have on hand or to cater to specific diets. Feel free to get creative with it—the base recipe is flexible and forgiving!

• Mushroom Mix: I sometimes swap in shiitake or portobello mushrooms for a different earthy flavor.
• Nut Options: If you don’t have cashews, try 1/4 cup of cashew butter instead—it blends easier if your blender isn’t super powerful.
• Grain-Free: Skip the flour and use cornstarch or arrowroot powder as a thickener for a gluten-free option.
• Make it Cheesy: For non-vegan friends, a little shredded cheese on top before baking adds a delicious golden crust.

How to Make Mushroom Pot Pie with Puff Pastry Recipe

Step 1: Prepare Your Ingredients and Preheat

First things first, preheat your oven to 400°F. This is key so it’s hot and ready when you’re spooning on that puff pastry. Also, get your puff pastry thawed—follow the package instructions and be gentle handling it so it doesn’t tear. I like to set out a 10-inch oven-safe skillet or a similar-sized baking dish to assemble the filling and bake it directly.

Step 2: Sauté the Vegetables

Heat 2 tablespoons of olive oil in your oven-safe pan over medium-high heat. Toss in the finely diced onion, quartered cremini, roughly chopped oyster mushrooms, and diced carrots. Cook them, stirring occasionally, for about 7 minutes until the veggies start to brown lightly—that’s where the magic flavor begins. Then stir in the tomato paste and cook for another 2 minutes to bring out that deep, rich flavor. Add garlic, thyme, paprika, and pepper last, sautéing just until fragrant—about 30 seconds. Your kitchen is going to smell amazing by now!

Step 3: Deglaze and Thicken the Filling

Pour in the dry red wine (or water if you prefer) to deglaze the pan, scraping all those lovely browned bits off the bottom. Let it cook down for 2 to 3 minutes until the liquid evaporates. Now sprinkle the all-purpose flour over your veggie mixture and sauté for a minute. This step helps thicken your filling so it’s just perfect under the puff pastry.

Step 4: Blend the Creamy Sauce and Simmer

While the veggies are cooking, blend together soaked cashews, vegetable broth, Worcestershire sauce (if using), and tamari in a high-speed blender until silky smooth—about 45 to 60 seconds. Pour this luscious sauce into the pan with your veggies and add the diced gold potatoes. Bring everything to a boil over high heat, then turn it down to medium and let it simmer for 10 to 12 minutes, stirring now and then. Just before finishing, toss in the frozen peas for a bright, sweet touch and remove from heat.

Step 5: Assemble and Bake Your Pot Pie

If you’re using a different baking dish, transfer the filling from the pan now. Roll out your puff pastry if needed to cover the top completely with about an inch overhang. Lay the pastry over the filling and carefully tuck the edges under, pinching it around the rim. Don’t forget to cut several 1-inch slits in the top to let steam escape during baking—that keeps your pastry perfectly crisp, no soggy spots. Finally, brush the top with non-dairy milk for a beautiful golden glaze. Place the pot pie onto a baking sheet to handle any overflow, then bake on the middle rack for 25 to 30 minutes until the crust is crisp and golden and the filling bubbles up through the slits. Let it rest 10 minutes before serving—it really helps it set up beautifully.

How to Serve Mushroom Pot Pie with Puff Pastry Recipe

Garnishes

I like to finish this pot pie with a sprinkle of fresh thyme or chopped parsley—something green to brighten up the rich filling and add a fresh aroma. Sometimes a little cracked black pepper on top right before serving kicks it up a notch.

Side Dishes

This pot pie is pretty hearty on its own, but I often serve it with a simple mixed greens salad dressed with lemon vinaigrette to add some brightness and crunch. Roasted Brussels sprouts or garlic green beans also make excellent complements.

Creative Ways to Present

If I’m feeling fancy, I bake individual pot pies in ramekins with small rounds of puff pastry on top—it feels elegant and personal, perfect for dinner parties. You can also use cookie cutters to create fun shapes on your top crust to add a whimsical touch kids love!

Make Ahead and Storage

Storing Leftovers

I store leftover pot pie tightly covered in the fridge for up to 5 days. I’ve found that keeping it well sealed prevents the pastry from getting soggy and keeps flavors fresh.

Freezing

Freezing the entire pot pie is totally doable—I wrap it well with foil and plastic wrap. When ready to eat, I thaw it overnight in the fridge and then reheat it in the oven to preserve that crispy crust. It’s like freshly baked all over again!

Reheating

To reheat, I pop leftovers in the oven at 350°F for about 15-20 minutes until warmed through. Microwaving works in a pinch but tends to soften the puff pastry, so if you can, go for the oven or toaster oven to keep it crisp.
