Ingredients You’ll Need

The beauty of this Vegan Mushroom Wellington with Pecans Recipe is in its earthy, natural flavors coming from the mushrooms, fresh herbs, and toasted nuts—all wrapped in that flaky, buttery puff pastry. Shopping for the best mushrooms you can find will really elevate the dish, and having your pastry cold but pliable makes all the difference.

• Vegan Puff Pastry: Use high-quality puff pastry and make sure it’s thawed overnight in the fridge but still cold to handle easily.
• Olive Oil (or butter): I use olive oil for a clean flavor, but vegan butter can add richness.
• Mushrooms: A blend is ideal—cremini, king oyster, shiitake, portobello, and wild varieties bring various textures and umami layers.
• Onion: Adds sweetness and depth when sautéed.
• Garlic: Don’t be shy here—garlic amps up the savory notes.
• Fresh Rosemary: I love how rosemary’s piney aroma complements the mushrooms perfectly, but sage or thyme works well too.
• Kosher Salt: Essential for bringing out all the flavors.
• Sherry Wine (or Marsala, Ruby Port, or Wine): This splash adds a fantastic complexity; feel free to skip if you don’t have any on hand.
• Balsamic Vinegar: Just a touch for balanced acidity.
• Chopped, Toasted Pecans: This is what adds crunch and a subtle nuttiness that’s pure magic.
• Pepper: Freshly ground, for a mild kick.
• Truffle Oil (optional): It’s a game-changer for that luxe earthy aroma.
• Cheese Options (optional): If you’re not strictly vegan, adding pecorino, gruyère, or even a vegan cheese can make it extra decadent.
• “Egg” Wash: Use nut milk, cream, or melted coconut oil for brushing the pastry to get that golden crust without eggs.

Variations

I’ve played around with this vegan mushroom Wellington quite a bit, and honestly, it’s a pretty forgiving recipe, so feel free to make it your own! Whether you want it fully vegan or with some cheese, or want to swap pecans for another nut you adore, it’ll turn out great.

• Adding Cheese: My family goes crazy when I fold in a bit of pecorino or a vegan ricotta — it adds creaminess that balances the earthiness perfectly.
• Different Nuts: Hazelnuts or walnuts work wonderfully too if pecans aren’t your thing or you need a substitute.
• Herb Swaps: I’ve swapped rosemary for sage or thyme depending on what’s fresh in my garden—each gives a distinct, delicious twist.
• Wine-Free Version: If you prefer to skip the alcohol, just add a little extra balsamic vinegar and some vegetable broth for that depth.

How to Make Vegan Mushroom Wellington with Pecans Recipe

Step 1: Prep and Sauté the Mushrooms

First, make sure your puff pastry is thawed overnight in the fridge, still cold but pliable—this is a crucial step to get a beautiful flaky crust. Preheat your oven to 400°F. Then slice all your mushrooms—this mix is key to getting a lovely texture and deep flavor. Heat the olive oil in a large skillet or Dutch oven over medium-high heat, and toss in the mushrooms, diced onion, garlic, salt, and fresh rosemary. As you sauté, you’ll notice the mushrooms start releasing a lot of moisture. Here’s what I learned: be patient and keep the heat moderate so the liquid evaporates completely — this prevents a soggy Wellington later on!

Step 2: Deglaze and Add Pecans

Once the mushrooms are pretty dry, splash in your sherry wine and balsamic vinegar. This adds a rich, tangy depth that really elevates the whole dish. Keep cooking until all the liquid evaporates again—don’t rush this step! After everything’s nice and dry, stir in those toasted chopped pecans, freshly ground pepper, and a drizzle of truffle oil if you’re feeling fancy. Taste and adjust the salt—it’s the little things that make this filling sing. If you want, fold in some cheese now for extra richness.

Step 3: Assemble the Wellington

Carefully unroll one sheet of your chilled puff pastry onto a parchment-lined baking sheet. If it feels stiff, let it rest a few minutes to warm slightly—just enough to roll gently without cracking. Roll it out a bit, just to smooth it and stretch by about half an inch. No need to go paper-thin here! Patch any holes with extra dough, so it seals well. Pile half the mushroom mixture along the center of the pastry, then quickly but carefully roll it up around the filling, seam side down. Repeat for the second sheet and filling.

Step 4: Score and Bake

This is where you can get a little creative or keep it simple—use a sharp knife or razor blade to gently score the top however you like: cross-hatch, leafy vines, or diagonal slashes work beautifully and help steam escape during baking. Brush the tops with nut milk or melted coconut oil for a beautiful golden finish. Bake on the middle rack for about 35 minutes, but start checking around 20 minutes and rotate your pan for even browning if needed. I’ve learned that letting the pastry turn a deep golden brown (not pale!) makes all the difference in flakiness and flavor. If you have a convection setting, use it for the last 5-10 minutes—it crisps things up wonderfully!

Once done, let your delicious Mushroom Wellington rest for 5-10 minutes before slicing and serving. This helps the filling set so it doesn’t spill out.

How to Serve Vegan Mushroom Wellington with Pecans Recipe

Garnishes

I love garnishing this Wellington with fresh rosemary sprigs—that piney aroma adds a lovely finishing touch. A sprinkle of flaky sea salt on top straight out of the oven also makes those buttery layers pop.

Side Dishes

My go-to sides are roasted root vegetables, garlicky sautéed greens like kale or spinach, and a simple mixed green salad with a bright vinaigrette. The rich Wellington pairs perfectly with fresh, crisp veggies to balance the richness.

Creative Ways to Present

For holiday dinners, I’ve served slices on a bed of creamy mashed potatoes or alongside a drizzle of vegan mushroom gravy—so elegant! Wrapping each slice with a fresh rosemary sprig adds a rustic yet festive look that always gets compliments.

Make Ahead and Storage

Storing Leftovers

I let the Wellington cool completely, then wrap leftovers tightly in foil and store in the fridge for up to 3 days. When I reheat, the pastry stays surprisingly flaky if done right.

Freezing

This Vegan Mushroom Wellington with Pecans freezes beautifully. I usually assemble and roll it, then wrap it tightly in plastic wrap and foil before freezing. When ready to bake, thaw overnight in the fridge and bake as directed—the tricky part is patience, but it’s totally worth it!

Reheating

To warm up leftovers, I pop slices into a 350°F oven for about 10-15 minutes on a parchment-lined baking sheet. This brings back that crisp puff pastry and heats the filling evenly without drying it out like a microwave would.
