Ingredients You’ll Need

I’ve found that combining a few key fresh vegetables with umami-packed mushrooms and a creamy cashew base really makes this pot pie shine. Plus, using store-bought puff pastry keeps it simple without skimping on that indulgent flaky crust.

• Puff Pastry Sheet: Thaw according to package instructions for a perfectly flaky crust without the fuss of making dough from scratch.
• Olive Oil: For sautéing and bringing those veggies to life with a little richness.
• Yellow Onion: Adds sweetness and depth when finely diced.
• Cremini Mushrooms: These give an earthy, meaty flavor that’s super satisfying.
• Oyster Mushrooms: Roughly chopped, they add a lovely texture contrast in the filling.
• Carrots: Diced for a gentle sweetness and a pop of color.
• Tomato Paste: Just a spoonful to boost the umami and tether the flavors together.
• Garlic Cloves: Minced fresh for fragrant bite—don’t skip it!
• Fresh Thyme Leaves: Herbal brightness that complements the mushrooms beautifully.
• Paprika: A dash to add a subtle warmth and depth.
• Black Pepper: Freshly ground to taste, to keep things lively.
• Dry Red Wine (or water): For deglazing and adding complexity; feel free to swap for water if preferred.
• Gold Potatoes: Small diced for body and heartiness in each bite.
• All-Purpose Flour: To thicken the luscious filling without clumping.
• Cashews: Soaked and blended to create a creamy base that mimics dairy perfectly.
• Vegetable Broth: Adds savory goodness to the sauce.
• Vegan Worcestershire Sauce (Optional): Boosts the depth and umami; totally worth it if you have it.
• Low-Sodium Tamari or Soy Sauce: Just a splash to elevate the flavors.
• Frozen Peas: Stirred in last for a pop of sweetness and color.
• Non-Dairy Milk: Brushed on the pastry top for that golden, shiny finish.

Variations

I love how versatile this Vegan Mushroom Pot Pie Recipe is — you can easily make it your own with just a few tweaks. Don’t be afraid to experiment based on what’s in season or your personal taste preferences.

• Adding Different Veggies: I sometimes toss in chopped kale or spinach for extra greens, and it blends beautifully with the creamy mushroom filling.
• Swap the Mushrooms: Button or shiitake mushrooms also work well if you can’t find cremini or oyster — just adjust cooking times so they don’t get too soft.
• Make It Gluten-Free: Use a gluten-free flour blend for the thickener and swap puff pastry with your favorite gluten-free crust option.
• Spicy Kick: A pinch of cayenne or smoked paprika brings a nice little warmth if you like a bit of heat.

How to Make Vegan Mushroom Pot Pie Recipe

Step 1: Prep Your Ingredients and Puff Pastry

Before you start cooking, preheat your oven to 400°F. Put your baking sheet and a 10” oven-safe pan (cast iron is my favorite for this) nearby. Make sure your puff pastry is thawed according to the package instructions — I usually thaw mine in the fridge overnight or on the counter for about 30 minutes. Get all your veggies diced: onions finely, carrots and potatoes in small pieces for even cooking, and mushrooms quartered or chopped. This little prep saves you time mid-cook and keeps things smooth.

Step 2: Sauté the Vegetables and Mushrooms

Heat 2 tablespoons of olive oil in your oven-safe pan over medium-high heat. Add the onion, cremini, oyster mushrooms, and diced carrots. Cook, stirring occasionally, until the veggies soften and the mushrooms begin to brown lightly — about 7 minutes. This browning is where the flavor magic starts! Then stir in a tablespoon of tomato paste and cook another 2 minutes to deepen that umami flavor. Add your minced garlic, fresh thyme, paprika, and black pepper; sauté just until fragrant, about 30 seconds. Be careful here not to burn the garlic — keep it moving!

Step 3: Deglaze and Thicken the Filling

Pour in ½ cup dry red wine or water to deglaze the pan. Scrape up all those tasty browned bits stuck to the bottom — they add so much flavor! Let it simmer until almost all the liquid has evaporated, about 2 to 3 minutes. Sprinkle 3 tablespoons of flour evenly over the veggie mixture and stir well; cook for 1 minute to get rid of the raw flour taste and begin thickening the filling.

Step 4: Blend Cashews and Build the Creamy Filling

I soak cashews in hot water for at least 30 minutes — my high-powered blender makes it possible to soak this short. Blend these with 2 cups of vegetable broth, 2 teaspoons vegan Worcestershire sauce (optional but recommended!), and 1 tablespoon tamari or soy sauce until silky smooth, about 45-60 seconds. Add this creamy sauce to your pan along with the small diced potatoes. Bring the mixture to a boil over high heat, then reduce to medium and let it gently simmer for 10 to 12 minutes, stirring now and then — the potatoes will cook through, and the filling will thicken beautifully.

Step 5: Stir in Peas and Assemble the Pot Pie

Once the filling has thickened and the potatoes are tender, stir in 1 cup of frozen peas, then remove from the heat. If you’re not using the same pan for baking, transfer this delicious filling to your baking dish now. Roll out (or shape) your puff pastry to cover the top of the pan with a slight 1-inch overhang — I like to tuck and pinch the edges for a neat finish. Use a sharp knife to cut several 1-inch slits on top; this helps steam escape during baking. Lastly, brush the puff pastry with 2 tablespoons of non-dairy milk — this adds that gorgeous golden glow we all love.

Step 6: Bake Until Golden and Bubbling

Place the pot pie on your prepared baking sheet to catch any drips, then pop it into the oven’s middle rack. Bake for 25 to 30 minutes until the puff pastry is golden and flaky and the filling bubbles up invitingly underneath. Let it cool and set for about 10 minutes before digging in — this rest time makes serving easier and lets the filling thicken up just right.

How to Serve Vegan Mushroom Pot Pie Recipe

Garnishes

I often sprinkle some freshly chopped parsley or thyme leaves on top just before serving—it looks beautiful and adds a fresh herbal note that brightens the rich filling. Sometimes a light drizzle of truffle oil amps up the mushroom earthiness if I’m feeling fancy.

Side Dishes

To complement the Vegan Mushroom Pot Pie Recipe, I love serving it with a crisp green salad tossed with lemon vinaigrette or some roasted Brussels sprouts. A simple steamed green bean almondine is another favorite because it adds crunch and freshness without competing with the pot pie’s savory richness.

Creative Ways to Present

For special occasions, I sometimes make individual pot pies in small ramekins topped with puff pastry rounds—so cute and perfect for portion control. You can also use a pie crust made from scratch for extra flair or garnish with edible flowers for a pop of color that really impresses guests.

Make Ahead and Storage

Storing Leftovers

I usually cool any leftovers completely, then cover the pot pie tightly with foil or plastic wrap and store it in the fridge for up to 5 days. Reheating in the oven the next day keeps the crust crispier than the microwave.

Freezing

I’ve frozen the filling separately and puff pastry separately for convenience. If freezing the assembled pie, wrap it tightly in foil and plastic wrap to prevent freezer burn. When ready to bake, thaw overnight in the fridge and then bake as directed, adding a few extra minutes if needed.

Reheating

To bring leftovers back to life, I pop them into a 350°F oven for about 15-20 minutes until heated through and the crust crisps back up. If you’re in a hurry, the microwave works too but expect a softer crust.
