Ingredients for Vegan Mushroom Wellington
Here’s everything you’ll need to make this showstopper. I swear by simple, fresh ingredients – they make all the difference between “good” and “oh-my-goodness-I-need-another-slice” amazing.
- 2 cups mushrooms (finely chopped – cremini are my favorite, but any will work!)
- 1 tbsp olive oil (the good stuff – it adds so much flavor)
- 1 small onion (diced small – trust me, you don’t want big chunks)
- 2 cloves garlic (minced – fresh is best, none of that jarred stuff here)
- 1 cup cooked lentils (pack them in – they give that perfect meaty texture)
- 1 tbsp soy sauce (that umami kick is everything)
- 1 tsp thyme (fresh if you’ve got it, dried works too)
- 1 tsp rosemary (same deal – fresh or dried both rock)
- 1 sheet vegan puff pastry (thawed – I keep mine in the fridge overnight)
- 2 tbsp plant-based milk (for that gorgeous golden crust)
See? Nothing crazy here – just straightforward ingredients that come together to make pure magic. Now let’s get cooking!
Equipment You’ll Need
Don’t worry—you won’t need any fancy gadgets for this Vegan Mushroom Wellington! Just grab these basics:
- A good skillet (for sautéing those mushrooms to perfection)
- Baking sheet (lined with parchment for easy cleanup)
- Rolling pin (to get that puff pastry just right)
- Sharp knife (for chopping and scoring the pastry)
That’s it! Now let’s make some magic happen.
How to Make Vegan Mushroom Wellington
Okay, let’s get into the nitty-gritty of making this Vegan Mushroom Wellington. It’s easier than it looks, I promise! Just follow these steps, and you’ll have a golden, flaky masterpiece in no time.
Preparing the Filling
First things first—preheat your oven to 375°F (190°C). While that’s warming up, let’s tackle the filling. Grab your skillet and heat up that olive oil over medium heat. Toss in the diced onion and let it soften for about 3 minutes—it should smell amazing already. Add the minced garlic and cook for another minute, just until it’s fragrant. Next, throw in the mushrooms, lentils, soy sauce, thyme, and rosemary. Stir everything together and let it cook for about 8-10 minutes, or until the mushrooms have released their liquid and most of it has evaporated. You want the filling to be moist but not watery—this is key to avoiding a soggy pastry later. Set it aside to cool slightly while you prep the pastry.

Assembling the Wellington
Now, roll out your thawed puff pastry on a lightly floured surface. You want it to be big enough to wrap around the filling—about 12×12 inches works great. Spread the mushroom mixture evenly down the center of the pastry, leaving about 2 inches on each side. Carefully fold the pastry over the filling, like you’re wrapping a present. Press the edges together to seal them, then crimp them with a fork to make sure they stay put. Brush the top with plant-based milk—this will give it that gorgeous golden-brown finish. If you’re feeling fancy, use a sharp knife to score a few decorative slits on top for steam to escape.

Baking to Perfection
Transfer your Wellington to a parchment-lined baking sheet and pop it in the preheated oven. Bake for 30 minutes, or until the pastry is golden brown and puffed up beautifully. Trust me, your kitchen is going to smell incredible. Once it’s done, let it cool for about 5 minutes before slicing—this helps the filling set so it doesn’t spill out everywhere. Then, slice it up and serve! You’re about to impress everyone at the table.
Tips for the Best Vegan Mushroom Wellington
Want your Wellington to be absolutely perfect? Here are my tried-and-true secrets:
- Dry that filling! Cook the mushroom mixture until almost all liquid evaporates—soggy filling means soggy pastry.
- Fresh herbs make magic. If you can, use fresh thyme and rosemary—they add such vibrant flavor.
- Don’t skip the milk wash. That plant-based milk gives the pastry its gorgeous golden shine.
Follow these tips, and you’ll have a Wellington that’s crisp, flavorful, and downright irresistible!
Variations and Substitutions
Listen, I know we don’t always have exactly what a recipe calls for—that’s why I love this Wellington’s flexibility! Here are my favorite swaps:
- Mushroom mix-up: Try shiitake for extra umami or portobello for meatier texture. Heck, use whatever’s on sale!
- Gluten-free? No problem—just grab GF puff pastry (most brands carry it now).
- Lentil alternatives: Crumbled walnuts or cooked quinoa work beautifully if you’re out of lentils.
The beauty? It still turns out delicious every time. That’s my kind of recipe!
Serving Suggestions
Oh, let’s talk presentation! This Vegan Mushroom Wellington deserves a plate as stunning as it is. Slice it thick and serve with a pile of roasted Brussels sprouts or garlicky green beans—the crispy edges pair perfectly with that flaky pastry. A simple arugula salad with lemon vinaigrette? Absolute magic. For holidays, add cranberry sauce on the side for that sweet-savory punch. Honestly, it’s so flavorful, it could sit on a bed of rice or quinoa if you want to bulk it up. But my favorite? Just a big ol’ slice straight to the plate—no frills needed!
Storing and Reheating Vegan Mushroom Wellington
Okay, let’s talk leftovers—because let’s be real, you might not finish this whole Wellington in one sitting (though I wouldn’t blame you if you did!). Store any slices in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy it again, skip the microwave—trust me, it’ll turn the pastry soggy. Instead, pop it in a 350°F oven for 10-15 minutes until it’s crispy and warm all the way through. It’ll taste just as amazing as day one!
Nutritional Information
Here’s the scoop on what you’re getting in each glorious slice (based on standard ingredients, but yours may vary slightly): about 280 calories, 8g plant-powered protein, and a solid 5g fiber to keep you satisfied. All estimates, of course—because let’s be honest, no one measures olive oil perfectly!
Frequently Asked Questions
Can I freeze this Vegan Mushroom Wellington?
Absolutely! Wrap the unbaked Wellington tightly in plastic wrap, then foil—it’ll keep beautifully in the freezer for up to 1 month. When ready, bake straight from frozen (just add 10-15 extra minutes). Already baked? Slice and freeze portions for quick future meals.
Is this recipe gluten-free?
Only if you use gluten-free puff pastry (which works great!). Regular puff pastry contains wheat flour, but most grocery stores carry GF versions now—just check the labels carefully.
Can I make this ahead for a dinner party?
You bet! Assemble the Wellington up to a day in advance and keep it refrigerated (unbaked). Brush with plant milk right before baking—it’ll taste freshly made!
What if my pastry tears while wrapping?
No panic! Just patch it with a small piece of extra pastry—once baked, no one will ever know. My first attempt looked like a pastry quilt, and it still tasted incredible!
