If you’re craving pure comfort in a bowl, Mushroom Pot Pie is your new best friend.

Whether you’re plant-based or just a mushroom lover, this pie proves that hearty, homey goodness doesn’t need meat.

Ingredients You’ll Need

The beauty of this Mushroom Pot Pie is in its simplicity: each ingredient plays a starring role, contributing flavor, texture, or pure comfort. Here’s what you’ll need, along with a few words on why each one shines in this savory classic:

• Dried porcini mushrooms: These pack a punch of earthy, woodsy flavor. Soaking them adds glorious depth to the filling and the reserved soaking liquid becomes liquid gold.
• Assorted fresh mushrooms (oyster, cremini, portobello): A medley creates irresistible texture and a full mushroom flavor spectrum—slice them thin for the best bite.
• Avocado oil: Its high smoke point is perfect for sautéing, and it introduces a subtle richness that works perfectly here.
• Kosher salt & black pepper: Essential for seasoning and coaxing out all those savory notes.
• White onion, carrots, and celery: This classic trio gives body, sweetness, and the irresistible base to your pie.
• Fresh garlic and herbs (thyme, oregano, parsley): Freshly minced, they bring that garden-fresh punch and make your kitchen smell like a dream.
• Garlic powder, onion powder, paprika: These create layers of flavor, adding warmth and gentle spice.
• Vegan butter: Adds a creamy richness to the filling and gives you that gorgeous golden finish on your pastry.
• All-purpose flour: Just enough to thicken the sauce to luscious, spoon-coating perfection.
• Vegetable broth: Deepens the flavor profile and brings everything together.
• Extra-creamy non-dairy milk: Contributes lovely silkiness without overpowering the mushrooms. (Avoid flavored milks!)
• Lacinato kale: For a pop of green and a sturdy leafy texture. Chop it roughly so it holds up in the filling.
• Puff pastry sheet: The crowning glory! Make sure it’s thawed, for light, crispy, bakery-style results every time.

Variations

One of the best parts about Mushroom Pot Pie: it’s endlessly adaptable! You can easily tweak the ingredients or go for gluten-free or dairy-free twists to suit your mood, your pantry, or your dinner guests.

• Swap out the greens: Not a kale lover? Spinach, chard, or even finely shredded cabbage all work beautifully.
• Add white beans: Stir in a cup of cooked cannellini or navy beans for extra protein and creamy texture.
• Cheesy top: Sprinkle shredded vegan cheese over the puff pastry before baking for an ultra-decadent golden crust.
• Make it gluten-free: Use gluten-free flour for thickening and swap in a gluten-free puff pastry for the topping.

How to Make Mushroom Pot Pie

Step 1: Rehydrate the Porcini Mushrooms

Pour one cup of boiling water over the dried porcini mushrooms, letting them steep for about 20 minutes while you prep the other ingredients. Once they’re plump and fragrant, thinly slice the mushrooms and make sure to save that flavorful soaking water—it’s like a magic potion for the filling.

Step 2: Sauté the Mushrooms

Heat avocado oil in a wide, oven-safe skillet over medium heat. Add your fresh mushrooms and the rehydrated porcini, sprinkling everything with salt and pepper. Sauté, stirring often, until most of the liquid has cooked off and your mushrooms are deeply browned—about 8–10 minutes. If your pan’s bursting at the seams, don’t hesitate to do this in two or three batches for the best caramelization.

Step 3: Build the Flavor

Toss in the minced onion, carrots, celery, garlic, and all your chopped fresh herbs. Season with garlic powder, onion powder, and paprika. Keep cooking, stirring frequently, until the onions turn tender and the whole mixture is mouthwateringly aromatic—just 2–3 minutes.

Step 4: Make the Roux

Drop 4 tablespoons of vegan butter into the pan and let it melt. Sprinkle the flour over the veggies and stir it in to coat everything. Give it a quick 2–3 minute cook to banish any raw flour taste and lay the groundwork for a perfectly thickened filling.

Step 5: Create the Creamy Filling

Pour in the reserved porcini soaking liquid, vegetable broth, and extra-creamy non-dairy milk. Mix everything together, then add the chopped kale in batches, stirring it into the saucy mushroom mixture. Once the kale is nestled in, bring the filling to a gentle simmer—the sauce should reduce and thicken by about a third. Taste, adjust the seasoning, and get ready for the pastry stage!

Step 6: Top with Puff Pastry & Bake

Roll the puff pastry out on a lightly floured surface and cut it into squares about 3 to 4 inches each (expect 16–18 pieces). Layer these over the filling, slightly overlapping, for gorgeous bakery-style flakiness. Brush the tops with your remaining melted vegan butter and slide the skillet into a 400°F oven. Bake for 20–30 minutes, until the pastry is golden and the filling bubbles around the edges. Let it cool just a touch before scooping out generous helpings of Mushroom Pot Pie.

How to Serve Mushroom Pot Pie

Garnishes

For that finishing touch, sprinkle the hot Mushroom Pot Pie with fresh parsley or a flourish of chives. A quick twist of black pepper or a light drizzle of good olive oil elevates the whole experience—simple but oh-so-pretty.

Side Dishes

This pot pie is a meal in itself, but a crisp green salad tossed with lemon vinaigrette or a plate of roasted root veggies makes a beautiful, balanced spread. And if you’re feeling extra, serve with a big bowl of garlicky mashed potatoes to soak up all that luscious gravy.

Creative Ways to Present

Mushroom Pot Pie is stunning as a big, rustic skillet bake, but for a dinner party, spoon the filling into individual ramekins and top each with a square of puff pastry—adorable and oh-so-luxe. For brunch, serve it in wide mugs with a dramatic wedge of pastry perched on top!

Make Ahead and Storage

Storing Leftovers

Leftover Mushroom Pot Pie will keep wonderfully in the fridge for up to three days. Be sure to cover the skillet or transfer portions to an airtight container to keep the filling moist and the pastry from absorbing too much steam.

Freezing

You can freeze the cooled filling (without the puff pastry) in a freezer-safe bag or container for up to two months. When you’re ready to bake, thaw it overnight in the fridge, pop it in a skillet, and proceed with the puff pastry step. Freezing with the pastry on top is possible, but tends to sacrifice that flaky magic.

Reheating

To reheat, set the oven to 350°F and warm the pie (covered with foil) until bubbling hot, about 20 minutes. If reheating single servings, pop them in the oven or toaster oven to help the pastry re-crisp, or microwave briefly then finish in the oven for best texture.
