Ingredients You’ll Need
The ingredients for this Mushroom Pot Pie with Puff Pastry Recipe come together beautifully to create layers of flavor and texture. I always recommend fresh mushrooms for that earthy depth, while simple pantry staples bring the whole thing home.
- Puff pastry sheet: Thawed according to package instructions; feel free to use a vegan version if desired.
- Olive oil: Adds a subtle fruity richness for sautéing the veggies.
- Yellow onion: Finely diced to melt sweetly into the filling.
- Cremini mushrooms: Quartered for hearty mushroom flavor and texture.
- Oyster mushrooms: Roughly chopped to add a delicate texture contrast.
- Carrots: Diced small to bring sweetness and color.
- Tomato paste: Intensifies the savory, umami notes of the filling.
- Garlic: Minced fresh garlic for aromatic warmth.
- Fresh thyme leaves: Adds herbal brightness.
- Paprika: A pinch for smoky depth and subtle spice.
- Black pepper: Freshly ground for a little kick.
- Dry red wine (or water): For deglazing and building richness; red wine is my personal favorite.
- Gold potatoes: Small-diced to give the filling body and creaminess once cooked.
- All-purpose flour: Used to thicken the filling perfectly.
- Cashews: Soaked to create a creamy dairy-free sauce when blended smooth.
- Vegetable broth: The base liquid that brings everything together.
- Vegan Worcestershire sauce (optional): Boosts savory complexity.
- Low-sodium tamari or soy sauce: Adds salty umami without overpowering.

Variations
I’m a huge fan of experimenting with this Mushroom Pot Pie with Puff Pastry Recipe because it’s so flexible—you can make it your own in so many delicious ways. Don’t be afraid to swap mushrooms, tweak the herbs, or sneak in some extra veggies based on what you love or have on hand.
- Adding protein: I’ve tossed in cooked lentils or shredded tofu for a heartier meal, and my family loves it.
- Seasonal veggies: Swap carrots for parsnips or add in some chopped kale for a green punch.
- Dairy-free swap: Using cashew butter instead of soaked cashews is a great shortcut if your blender isn’t super powerful.
- Spice it up: A dash of cayenne or smoked paprika gives it a lovely smoky heat I sometimes crave on cold nights.
How to Make Mushroom Pot Pie with Puff Pastry Recipe
Step 1: Prepare Your Workspace and Preheat Oven
First things first, set your oven to 400°F. I like to place a baking sheet and my 10-inch oven-safe cast-iron pan nearby—it really helps when assembling and baking. Make sure your puff pastry is thawed just right according to package instructions, not too soft or still frozen, for the best puff during baking.
Step 2: Sauté the Aromatics and Vegetables
Heat 2 tablespoons of olive oil in your cast-iron pan over medium-high heat. Toss in the finely diced yellow onion, quartered cremini mushrooms, roughly chopped oyster mushrooms, and diced carrots. Stir gently and cook them for about 7 minutes until they’re lightly browned and smelling amazing. Then stir in 1 tablespoon of tomato paste and cook for another 2 minutes. Add your minced garlic, fresh thyme leaves, paprika, and black pepper—don’t skip this step because it fills your kitchen with those cozy, irresistible aromas!
Step 3: Deglaze and Thicken the Filling
Pour in ½ cup of dry red wine (or water if you prefer). Use your spatula to scrape up all the delicious browned bits stuck to the pan—this is where much of the flavor lives. Cook the liquid for 2-3 minutes until it mostly evaporates. Then sprinkle 3 tablespoons of all-purpose flour over the veggies and stir for about a minute to start thickening the filling.
Step 4: Blend the Cashews and Simmer the Filling
While the flour toasts, blend together ½ cup soaked cashews, 2 cups vegetable broth, 2 teaspoons vegan Worcestershire sauce (optional), and 1 tablespoon tamari until smooth and creamy. Pour this luscious mixture into the pan along with the small-diced gold potatoes, stirring to combine well. Crank the heat to high until it boils, then lower to medium and let it simmer for 10-12 minutes, stirring occasionally, so the potatoes soften and the sauce thickens beautifully. Toss in 1 cup frozen peas right at the end for a pop of freshness, then take the pan off the heat.
Step 5: Assemble the Pot Pie with Puff Pastry
If you aren’t using the same pan for baking, transfer the filling now. Roll out your puff pastry so it’s large enough to cover the top with about a 1-inch overhang. Drape the pastry over your pan, trim the edges, then tuck and pinch the excess under the rim. Don’t forget to cut six small slits in the top dough to let steam escape—that little step keeps your crust from getting soggy! Brush the whole top with 2 tablespoons of non-dairy milk for a golden, shiny finish.
Step 6: Bake and Enjoy
Place the pan on the baking sheet (to catch any spills) and slide it into the center rack of your preheated oven. Bake for 25 to 30 minutes until the puff pastry is puffed up, beautifully golden, and the filling is bubbling with goodness underneath. After baking, let it rest for about 10 minutes—this helps the filling set so it’s easier to serve. Then dig in while it’s warm and comforting!
Pro Tips for Making Mushroom Pot Pie with Puff Pastry Recipe
- Perfect puff pastry thawing: I learned that letting your puff pastry thaw in the fridge overnight yields the best flaky crust—too warm and it gets sticky and hard to handle.
- Cashew soaking shortcut: If you’re short on time, I soak cashews in hot water for about 30 minutes to still get a creamy blend without overnight soaking.
- Don’t skip the wine: Deglazing with red wine adds an amazing depth, but water works fine if you don’t have any on hand.
- Vent slits are essential: Making small cuts in your puff pastry top prevents sogginess and helps the crust puff evenly—trust me on this one!
How to Serve Mushroom Pot Pie with Puff Pastry Recipe
Garnishes
I love sprinkling freshly chopped parsley or thyme right on top of each slice—it adds a fresh, herby finish that brightens the rich filling. A drizzle of truffle oil here and there can also elevate it if you’re feeling fancy!
Side Dishes
My go-to sides are always simple greens like a crisp arugula salad dressed with lemon vinaigrette or roasted garlic green beans. They add brightness and crunch to complement the creamy, flaky pot pie.
Creative Ways to Present
For special occasions, I like to make individual mushroom pot pies using ramekins topped with puff pastry cutouts shaped like leaves or mushrooms. It impresses guests and makes the meal feel extra cozy and personalized.
Make Ahead and Storage
Storing Leftovers
I store any leftovers in an airtight container in the fridge, and it stays fresh for up to 5 days. The flavors actually meld beautifully overnight, making the next-day bites even better.
Freezing
If you want to make this ahead for busy days, you can freeze the filling and puff pastry separately. Just thaw both before assembling and baking. I’ve done this several times, and while the freshly baked pot pie is best, the freezer option works well in a pinch.
Reheating
To keep that crust crisp when reheating leftovers, I pop the pot pie or slices back into a 350°F oven for 15 to 20 minutes. A microwave will warm things up faster but makes the crust less flaky.
FAQs
-
Can I make this Mushroom Pot Pie with Puff Pastry Recipe gluten-free?
Absolutely! Use a gluten-free puff pastry and substitute the all-purpose flour with a gluten-free blend or cornstarch for thickening. Just keep an eye on the texture as the thickening agent might absorb liquids differently.
-
What mushrooms work best?
I love using a mix of cremini and oyster mushrooms for an earthy, juicy texture. But button, shiitake, or portobello mushrooms can work just fine—mixing varieties gives the best flavor complexity.
-
Can I prepare this recipe ahead of time?
Yes! You can prepare the filling a day in advance and refrigerate it. Just assemble with your puff pastry and bake when you’re ready. This makes dinner super stress-free.
-
Do I have to use cashews in the filling?
The cashews add creaminess without dairy, but if you’re allergic or can’t use them, try substituting with cashew butter or even a dollop of vegan cream cheese. Each gives a slightly different but delicious effect.
Final Thoughts
This Mushroom Pot Pie with Puff Pastry Recipe has become a personal favorite for so many reasons—its cozy flavors, the easy puff pastry shortcut, and how it brings people together around the table. I used to struggle nailing a savory, rich filling that wasn’t overly complicated, but this recipe struck the perfect balance. I really hope you give it a try; it’s one of those dishes where the reward makes every step worth it. Trust me, once you taste that golden crust and creamy mushroom filling, you’ll find yourself making it over and over again!

Ingredients
For the 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 small gold potatoes, diced
- 3 tablespoons all-purpose flour
- 1/2 cup cashews, soaked
- 2 cups vegetable broth
- 2 teaspoons vegan Worcestershire sauce (optional, for deeper flavor)
- 1 tablespoon low-sodium tamari or soy sauce
- 1 cup frozen peas
For the Crust
- 1 sheet puff pastry, thawed according to package instructions
- 2 tablespoons non-dairy milk (for brushing)
Instructions
- Prep: Preheat your oven to 400°F (200°C). Set aside a baking sheet and a 10-inch oven-safe cast-iron skillet or similar-sized baking dish. Thaw the puff pastry following the package instructions.
- Aromatics: Heat the olive oil in the oven-safe sauté pan over medium-high heat. Add the diced onion, cremini mushrooms, oyster mushrooms, and carrots. Sauté for about 7 minutes, stirring occasionally, until the vegetables are lightly browned. Stir in the tomato paste and cook for an additional 2 minutes. Add the minced garlic, fresh thyme leaves, paprika, and black pepper; sauté for 30 seconds until fragrant.
- Deglaze: Pour in the red wine (or water, if substituting) to deglaze the pan, scraping up any browned bits. Cook for 2 to 3 minutes, or until the liquid has mostly evaporated. Sprinkle the flour evenly over the vegetables and sauté for 1 minute to cook out the raw flour taste.
- Simmer: In a blender, combine the soaked cashews, vegetable broth, vegan Worcestershire sauce, and tamari. Blend on high for 45 to 60 seconds until smooth and creamy. Add this cashew cream and the diced potatoes to the pan, stirring well. Bring the filling to a boil over high heat, then reduce the heat to medium and simmer for 10 to 12 minutes, stirring occasionally until the sauce thickens and potatoes are tender. Stir in the frozen peas and remove the pan from heat.
- Assemble: If using a different baking dish, transfer the filling there now. Roll out the puff pastry as needed to cover the pan with about a 1-inch overhang. Place the pastry over the filling, trim edges leaving a slight overhang, fold the excess pastry under and pinch to seal it to the edges of the pan. Use a knife to cut six 1-inch slits in the pastry top to allow steam to escape. Brush the pastry with non-dairy milk for a golden finish.
- Bake: Place the pot pie on the prepared baking sheet to catch any drips. Bake on the middle rack of the oven for 25 to 30 minutes, or until the puff pastry is golden brown and the filling is bubbling. Let the pot pie cool and set for 10 minutes before serving. Serve warm.
- Storage: Leftovers can be refrigerated for up to 5 days and reheated in the oven, toaster oven, or microwave.
Notes
- Cashews: If you own a high-powered blender like a Vitamix, soaking cashews in hot water for 30 minutes suffices. For less powerful blenders, soak cashews for several hours or overnight in the fridge for better creaminess.
- Cashew Butter Alternative: If your blender struggles with whole soaked cashews, substitute 1/4 cup cashew butter to achieve a smooth sauce texture.
