Ingredients You’ll Need

Believe it or not, the magic of this Vegan Wellington Recipe starts with simple, pantry-friendly ingredients. Each one plays a crucial role — from the crunch and depth of walnuts and cashews to the umami-rich mushrooms and the herbal brightness of fresh thyme and sage. Together, they create a layered filling that bursts with flavor and texture.

Olive oil (3 tbsp divided): Provides a smooth richness and helps sauté vegetables to perfection.
Walnuts (⅔ cup): Adds a toasty crunch and earthy depth.
Cashews (⅓ cup): Bring a creamy texture that balances the nuttiness.
Ground flaxseed (2 tbsp) and hot water (5 tbsp): Combine to make a flax “egg” that binds the filling naturally.
Carrots (1 finely chopped): Give a subtle sweetness and vibrant color.
Leek (1 finely chopped): Offers mild onion-like aroma and softness.
Yellow onions (2 finely chopped): Bring classic sweetness that rounds out the savory notes.
Garlic cloves (4 minced): Infuses the filling with aromatic warmth.
Shiitake mushrooms (3.5 oz finely chopped): Deliver rich umami and meaty texture.
Swiss brown mushrooms (7 oz finely chopped): Heighten the mushroomy goodness and add juiciness.
Fresh thyme (6 sprigs): Offers a fragrant herbal note that’s simply essential.
Sage leaves (3 finely chopped): Bring a slightly peppery, savory punch.
Sea salt flakes (½ tsp): Enhances and balances all the flavors.
Tamari (1 tbsp): Adds a deep, salty soy flavor.
Vegan Worcestershire sauce (1 tbsp): Gives tangy complexity with a touch of sweetness.
Cooked brown lentils (1.5 cups): Pack protein and add hearty texture.
Oats (¾ cup): Help bind the filling while contributing a subtle nuttiness.
Fresh parsley (⅓ cup finely chopped): Brightens the whole mixture with its fresh, grassy notes.
Salt and pepper to taste: Essential for seasoning to perfection.
Store-bought vegan puff pastry (2 squares): The beautiful, flaky crust that encases this masterpiece.
Maple syrup (2 tsp): For a hint of natural sweetness in the pastry glaze.
Dairy-free milk (1 tbsp): Helps create a golden glaze on the pastry while baking.

How to Make Vegan Wellington Recipe

Step 1: Prepare Your Ingredients

Start by washing and finely chopping all your vegetables — carrots, leek, onions, shiitake, and Swiss brown mushrooms — making sure everything is ready to go. Remember to remove thyme leaves from the sprigs and roughly chop the nuts. Preparing these elements ahead makes the following steps smoother and quicker.

Step 2: Make the Flaxseed “Egg”

Mix your ground flaxseed with hot water to create a natural binding agent that mimics an egg’s texture in this vegan recipe. Let it rest for about five minutes until it thickens slightly; this will be crucial for bringing your filling together perfectly.

Step 3: Toast the Nuts

Heat a tablespoon of olive oil in a large pan over medium heat, then add the walnuts and cashews. Cook them gently for about five minutes until golden and fragrant, stirring frequently so they toast evenly but don’t burn. This step unlocks their full nutty flavor and crunch.

Step 4: Sauté the Vegetables

In the same pan, add two more tablespoons of olive oil followed by the carrot, leek, and onions. Let them cook gently for 10 minutes, stirring regularly to soften and release their sweetness. Then add garlic, mushrooms, salt, thyme, and sage, and continue cooking for another 10 minutes to deepen the earthy flavors and ensure the mushrooms release their moisture.

Step 5: Add Flavor and Lentils

Stir in tamari, vegan Worcestershire sauce, and cooked brown lentils. Turn the heat down and let everything simmer together for 10 more minutes, allowing the lentils to soak up all those savory notes and the filling to thicken slightly.

Step 6: Combine the Filling

Transfer your cooked filling into a large mixing bowl. Add oats, fresh parsley, the flaxseed egg, and chopped nuts, then stir it all together thoroughly. For a creamier texture, pulse half the mixture briefly in a food processor and combine it back with the rest — this step helps your filling hold shape without being too dense.

Step 7: Chill the Filling

Pop the filling in the fridge for 20 minutes. This cool-down period makes the mixture easier to shape and better able to hold its form inside that stunning puff pastry.

Step 8: Assemble the Vegan Wellington

Preheat your oven to 375°F (190°C) on fan assist. Remove the vegan puff pastry from the freezer about 10 minutes before assembling. Lay a puff pastry sheet on baking paper, then pile and shape half the filling into a log down the center, leaving space at top and bottom. Score diagonal strips along each side, fold over the ends, and crisscross the strips to form a beautiful lattice wrapping around the filling. Repeat with the second pastry and filling batch to create a second Wellington.

Step 9: Apply the Glaze

Mix the maple syrup with dairy-free milk and gently brush this glaze over the pastry. This will give your Vegan Wellington Recipe its signature golden, glossy crust once baked — the kind of crust that makes everyone’s mouth water before the first slice is even cut.

Step 10: Bake and Rest

Bake your Wellington for 35 to 40 minutes until the pastry is golden and flaky, turning the tray halfway through for even cooking. If you’ve got multiple dishes in the oven, the time might extend a bit, so keep an eye on that gorgeous crust. Once done, let it rest for 10 minutes before cutting to allow the filling to settle for neat, satisfying slices.

Make Ahead and Storage

Storing Leftovers

The Vegan Wellington keeps wonderfully in the fridge for up to 3 days. Make sure it’s tightly wrapped or stored in an airtight container to maintain crispness in the pastry and freshness in the filling.

Freezing

This recipe is freezer-friendly at two stages: you can freeze the assembled but unbaked Wellingtons wrapped well in cling film and foil, or freeze individual baked slices. When freezing unbaked, thaw fully in the fridge overnight before brushing with vegan egg wash and baking. For baked slices, simply thaw gently and reheat as needed.

Reheating

To reheat, place your Vegan Wellington or slices in a preheated oven at 350°F (175°C) until warmed through and the pastry re-crisps, about 15 to 20 minutes. Avoid microwaving to ensure the pastry stays flaky and delicious.

FAQs

Can I make this Vegan Wellington Recipe nut-free?

Absolutely! You can substitute the walnuts and cashews with seeds like sunflower or pumpkin seeds to get that crunch and depth without nuts. Just toast them lightly for best flavor.

Is the pastry store-bought or homemade?

Store-bought vegan puff pastry works great for ease and convenience, but if you’re up for it, homemade vegan puff pastry would add an impressive personal touch and even flakier texture.

Can I prepare the filling in advance?

Yes, you can make the filling a day ahead and keep it refrigerated. Chilling it not only helps with assembly but also allows flavors to meld beautifully.

What is the best way to reheat leftovers without drying out the pastry?

Reheating in an oven at moderate heat helps keep the pastry crispy and prevents it from becoming soggy, which can easily happen in the microwave.

Can I use other mushrooms besides shiitake and Swiss brown?

Definitely! Feel free to experiment with your favorite mushrooms like cremini or portobello. Just keep in mind that different mushrooms vary in moisture and flavor intensity, so adjust cooking times and seasoning as needed.
