Ingredients You’ll Need
The ingredients here really work in harmony to create a rich, hearty, and deeply flavorful mushroom pot pie. A couple of shopping tips: look for fresh cremini and oyster mushrooms for that meaty texture, and if vegan, be sure to grab a puff pastry without butter.
- Puff Pastry: Thawed but chilled, this provides that flaky, buttery crust we all want.
- Olive Oil: A good quality oil helps sauté your veggies to perfection without overpowering flavors.
- Yellow Onion: Finely diced for sweetness and depth.
- Cremini Mushrooms: Quartered for that classic mushroom bite.
- Oyster Mushrooms: Roughly chopped adds texture and a delicate earthiness.
- Carrots: Diced small for subtle sweetness and color.
- Tomato Paste: Adds richness and a hint of umami.
- Garlic: Minced fresh garlic is key for aroma.
- Fresh Thyme: The fresh leaves brighten the whole dish.
- Paprika & Black Pepper: A touch of spice balances the flavors.
- Dry Red Wine (or Water): Deglazes the pan and lends complexity.
- Gold Potatoes: Small diced for a creamy bite that holds up well.
- All-Purpose Flour: Helps thicken the filling beautifully.
- Cashews (Soaked): Blended for a creamy, dairy-free base.
- Vegetable Broth: Adds savory depth.
- Vegan Worcestershire Sauce (optional): Adds a subtle tang and richness.

Variations
I love mixing things up based on what I have in my fridge or dietary preferences. Feel free to personalize this mushroom pot pie to make it your own—it’s easy to swap out ingredients or adjust seasonings.
- Add Protein: Sometimes I toss in cooked lentils or shredded jackfruit for extra heartiness when I want more plant-based protein.
- Use Different Mushrooms: Shiitake or cremini alone work great if oyster aren’t available.
- Dairy-Free Cream Alternatives: If you don’t have cashews soaked, 1/4 cup cashew butter works in a pinch for that creamy texture.
- Spice It Up: A pinch of cayenne or smoked paprika adds a subtle kick I really enjoy on chilly nights.
- Gluten-Free: Swap flour with a gluten-free blend and check your puff pastry choice to keep it suitable.
How to Make Mushroom Pot Pie with Puff Pastry Recipe
Step 1: Sauté the Vegetables to Build Flavor
Heat your olive oil in a 10-inch oven-safe cast iron or sauté pan over medium-high heat. Toss in the diced onion, cremini, oyster mushrooms, and carrots. Cook for about 7 minutes, stirring occasionally, until you see lovely browning develop—this caramelization forms the flavor base of your filling. Add the tomato paste and stir in for 2 more minutes—this punch of umami deepens the dish. Then add the minced garlic, thyme leaves, paprika, and black pepper, sautéing just until fragrant, about 30 seconds. Keep an eye on the garlic so it doesn’t burn!
Step 2: Deglaze and Thicken the Filling
Pour in the red wine (or water if you prefer) to deglaze the pan, scraping up all the brown bits stuck to the bottom—they’re packed with flavor! Let the liquid cook off for 2-3 minutes, concentrating the taste. Sprinkle the flour evenly over the veggies and cook for 1 minute while stirring constantly; this step helps your filling thicken nicely once you add the liquids.
Step 3: Blend Your Creamy Cashew Mixture and Simmer
While the veggies cook, blend the soaked cashews, vegetable broth, vegan Worcestershire sauce (if using), and tamari in a high-speed blender until silky smooth, about 45 to 60 seconds. Pour this creamy mixture into your pan along with the diced potatoes. Stir everything to combine. Bring the filling up to a boil over high heat, then reduce to medium, letting it simmer for 10-12 minutes until the potatoes are tender and the sauce thickens. Finally, fold in your frozen peas for a pop of color and sweetness before removing the pan from heat.
Step 4: Assemble and Prepare for the Oven
Make sure your puff pastry is thawed but still cold. If it needs a little rolling out to cover your pan, go ahead carefully on a floured surface. Transfer the mushroom filling to your baking pan if you used a different saute pan. Drape the pastry over the top with about a 1-inch overhang, then fold the edges under and pinch to seal it tightly to the rim. Cut six slits on top of the pastry so steam can escape—this keeps the crust crisp and prevents sogginess. Finally, brush the top lightly with your non-dairy milk to get that beautiful golden color when it bakes.
Step 5: Bake Until Beautifully Golden
Set the pot pie on a baking sheet to catch any drips, then slide it onto the middle rack of your preheated oven at 400°F. Bake for about 25 to 30 minutes until the crust turns golden and the filling is bubbly around the edges. After taking it out, let the pie rest and set for 10 minutes—this helps the filling thicken a bit and makes serving easier. Then slice up and enjoy!
Pro Tips for Making Mushroom Pot Pie with Puff Pastry Recipe
- Thaw Puff Pastry Properly: Don’t rush thawing; a cold but pliable sheet makes rolling and handling much smoother.
- Soak Cashews Well: I soak mine overnight in the fridge for the creamiest texture, but hot soak for 30 minutes if you’re short on time.
- Don’t Skip the Slits: Those cut-outs prevent soggy crust by letting steam escape during baking—trust me on this one.
- Use an Oven-Safe Skillet: If you don’t want to transfer filling, sauté and assemble in your oven-safe pan to save cleanup.
How to Serve Mushroom Pot Pie with Puff Pastry Recipe
Garnishes
I usually sprinkle fresh chopped parsley or thyme on top just before serving. It adds a bright herbal note and pretty contrast against the golden crust that I absolutely love. Sometimes a little flaky sea salt on the crust right after baking gives that final wow factor.
Side Dishes
My go-to sides with this mushroom pot pie are simple green salads or roasted Brussels sprouts. The freshness from the salad cuts through the richness perfectly, and roasted veggies add an extra cozy vibe without competing flavors.
Creative Ways to Present
For a special occasion, I’ve served individual pot pies using ramekins or small oven-safe bowls with puff pastry tops. It feels fancy yet personal, and everyone gets their own little flaky treasure. You can even use festive cut-outs on the pastry for holidays or gatherings!
Make Ahead and Storage
Storing Leftovers
I store leftover mushroom pot pie covered in the fridge for up to 5 days. I usually keep it in the baking dish covered tightly with foil or plastic wrap to keep it fresh. The flavors deepen overnight, and I find it reheats beautifully.
Freezing
Freezing fully assembled pot pie is possible but I prefer freezing the filling separately. Then I thaw the filling and assemble with fresh puff pastry when ready. This keeps the crust at its flakiest and the filling stays delicious.
Reheating
To reheat, I pop leftovers in a 350°F oven for 15-20 minutes, uncovered, to crisp the pastry back up. If you’re in a hurry, the microwave works too but you might lose that crispness—so if you can, the oven method is worth the wait.
FAQs
-
Can I make Mushroom Pot Pie with Puff Pastry Recipe gluten-free?
Yes! Use gluten-free all-purpose flour or a blend to thicken the filling, and be sure to select a gluten-free puff pastry (many stores carry this now). The texture might vary slightly, but it’ll still be delicious!
-
How do I soak cashews for the creamy filling?
For best results, soak cashews covered in water overnight in the fridge. If you’re short on time, pour hot water over them and soak for 30 minutes. Once soft, drain and blend with broth to get a smooth, creamy texture.
-
Can I use fresh peas instead of frozen?
Definitely! Fresh peas add a bright, sweet pop and can be folded in just like frozen peas. If using fresh, you might want to blanch them briefly to maintain vibrant color and texture.
-
What if I don’t have red wine for deglazing?
No worries—water or vegetable broth work perfectly fine as a substitute. The wine adds extra depth, but the other liquids keep the filling flavorful and moist.
-
How to prevent soggy puff pastry?
Make sure to cut slits in the pastry to release steam and bake the pot pie on a sheet pan to catch drips. Letting it rest before serving also lets the filling set, reducing sogginess.

Ingredients
Pot Pie Filling
- 2 tablespoons olive oil
- 1 yellow onion, finely diced
- 8 ounces cremini mushrooms, quartered
- 6 ounces oyster mushrooms, roughly chopped
- 1 cup diced carrots
- 1 tablespoon tomato paste
- 3-5 cloves garlic, minced
- 1 teaspoon fresh thyme leaves
- 1/2 teaspoon paprika
- 1/2 teaspoon black pepper
- 1/2 cup dry red wine (or substitute water)
- 2-3 gold potatoes, small dice
- 3 tablespoons all-purpose flour
- 1/2 cup cashews, soaked
- 2 cups vegetable broth
- 2 teaspoons vegan Worcestershire sauce (optional)
- 1 tablespoon low-sodium tamari or soy sauce
- 1 cup frozen peas
Assembly
- 1 sheet puff pastry, thawed according to package instructions
- 2 tablespoons non-dairy milk (for brushing)
Instructions
- Prep: Preheat your oven to 400°F (205°C). Set out a baking sheet and a 10-inch oven-safe cast-iron skillet or similar-sized baking dish. Thaw the puff pastry sheet according to package instructions so it’s ready to use.
- Aromatics: Heat the olive oil in the oven-safe sauté pan over medium-high heat. Add the diced onion, cremini and oyster mushrooms, and diced carrots. Sauté for about 7 minutes, stirring occasionally until the vegetables develop a light brown color. Stir in the tomato paste and continue cooking for 2 more minutes. Add the minced garlic, fresh thyme leaves, paprika, and black pepper, sautéing for 30 seconds until fragrant.
- Deglaze: Pour in the red wine or water to deglaze the pan, scraping the browned bits off the bottom. Cook for 2 to 3 minutes until the liquid has mostly evaporated. Sprinkle the all-purpose flour over the vegetables and sauté for 1 minute to cook the flour.
- Simmer: In a blender, combine soaked cashews, vegetable broth, vegan Worcestershire sauce (if using), and tamari or soy sauce. Blend for 45 to 60 seconds until smooth and creamy. Pour the blended mixture and the diced gold potatoes into the pan, stirring well to combine. Bring the filling to a boil over high heat, then reduce to medium and simmer for 10 to 12 minutes, stirring occasionally. Stir in the frozen peas and remove from heat.
- Assemble: If not using the oven-safe pan, transfer the filling to your baking dish. Roll out the puff pastry if needed to cover the pan with about a 1-inch overhang. Lay the pastry over the filling and trim edges, folding the overhang under to secure, then pinch the edges together. Using a knife, cut six 1-inch slits into the pastry top to allow steam to escape. Brush the pastry with non-dairy milk to encourage browning.
- Bake: Place the pot pie on the prepared baking sheet to catch any drips, then position on the middle rack of the oven. Bake for 25 to 30 minutes, until the pastry is golden and puffed and the filling is bubbling underneath. Remove from the oven and let cool for 10 minutes to set before serving. Enjoy warm. Leftovers keep well in the fridge for up to 5 days and reheat nicely in the oven, toaster oven, or microwave.
Notes
- Cashews: For a high-powered blender, soak cashews in hot water for about 30 minutes before blending. For less powerful blenders, soak cashews for several hours or overnight in the fridge for smoother results.
- Cashew Butter: If you don’t have soaked cashews or a strong blender, substitute 1/4 cup cashew butter instead of whole cashews for creaminess.
- Wine Substitute: Dry red wine can be replaced with water if preferred or to keep it alcohol-free.
- Puff Pastry Handling: Make sure your puff pastry is fully thawed but still cold for easy rolling and shaping.
- Storage: Store leftovers covered in the refrigerator up to 5 days. Reheat gently in the oven for best texture.
