Step‑by‑Step Instructions for Vegan Mushroom Wellington With Sweet Potatoes
Step 1: Prepare Puff Pastry
Begin by thawing the vegan puff pastry on a baking sheet lined with parchment paper. Leave it to warm up for about 25-30 minutes until it’s pliable yet firm, making it easier to roll out later. You’ll want it soft but not too sticky, ensuring a smooth assembly process.
Step 2: Sauté Onion
In a skillet over medium heat, warm 1 tablespoon of olive oil. Add the chopped onion and cook until it turns translucent, which should take about 3-4 minutes. Sprinkle in the coconut sugar, raise the heat to medium-high, and caramelize the onions until they are nicely browned and fragrant, about 4-5 minutes. Once ready, remove from the skillet and set aside.
Step 3: Cook Mushrooms
Using the same skillet, add the remaining 0.5 tablespoon of olive oil. Sauté the sliced mushrooms and minced garlic on medium heat for about 6-8 minutes, stirring frequently, until the mushrooms are golden and have released most of their moisture. After cooking, drain any excess liquid with paper towels to ensure a non-soggy Vegan Mushroom Wellington.
Step 4: Assemble Wellington
Now, roll out the puff pastry on a lightly floured surface, keeping a ¾-inch border. Spread the caramelized onions evenly down the center of the pastry. Next, layer the mashed sweet potato on top, followed by the cooked mushrooms. Drizzle the Dijon mustard, seasoning with salt, pepper, and fresh rosemary for a burst of flavor.
Step 5: Roll and Seal
Carefully roll the puff pastry over the filling, starting from one edge, to create a log shape. Gently press to seal the edges and ends completely, ensuring the filling is securely wrapped inside. You might want to give it a light pinch along the seam to prevent any leakage during baking.
Step 6: Prepare Vegan Egg Wash
In a small bowl, whisk together 1 tablespoon of aquafaba, 1 tablespoon of almond milk, 1 teaspoon of vegetable oil, and 1 tablespoon of maple syrup. This will create a glossy vegan egg wash. Brush this mixture generously over the surface of the rolled Wellington to give it a beautiful sheen, and use a sharp knife to create a cross-hatch pattern for an attractive finish.
Step 7: Chill
For optimal results, place the assembled Wellington in the freezer for about 10 minutes to firm up the pastry. This chilling step helps to achieve a flaky texture during baking and ensures that the filling stays contained when it puffs up in the oven.
Step 8: Bake
Preheat your oven to 375°F (191°C). Once hot, remove the Wellington from the freezer and place it on a baking sheet. Bake for approximately 40 minutes, or until the pastry turns golden brown and flaky. Keep an eye on its color, and if necessary, cover the ends with foil to prevent over-browning. Let it cool for 10 minutes before slicing into this delightful Vegan Mushroom Wellington with Sweet Potatoes.

How to Store and Freeze Vegan Mushroom Wellington with Sweet Potatoes
- Fridge: Store any leftovers in an airtight container for up to 5 days. To maintain optimal texture, ensure the Wellington is completely cooled before sealing.
- Freezer: You can freeze the assembled, uncooked Vegan Mushroom Wellington for up to 3 months. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn.
- Reheating: For best results, reheat baked slices in the oven at 350°F (177°C) for 10-12 minutes. This will revive the crispy pastry while warming the filling.
- Thawing: If frozen, allow the Wellington to thaw in the fridge overnight before baking. Bake directly from the fridge for approximately 40 minutes or until golden brown.
Make Ahead Options
These Vegan Mushroom Wellington with Sweet Potatoes are perfect for meal prep enthusiasts! You can prepare the filling (caramelized onions, sautéed mushrooms, and mashed sweet potatoes) up to 3 days in advance and store them in an airtight container in the refrigerator. To maintain the quality, allow the filling to cool completely before refrigerating and ensure it’s sealed tightly to prevent moisture loss. When you’re ready to assemble, simply roll out the thawed puff pastry, add your prepped filling, and follow the final steps for assembly and baking as directed. You’ll have a delicious, stress-free meal that will still impress your guests!

You can store leftovers in an airtight container in the refrigerator for up to 5 days. Just make sure the Wellington is cooled to room temperature before sealing.

What if the pastry is getting too dark while baking?
If you notice the ends of the Wellington browning too quickly, gently cover them with aluminum foil to prevent overcooking. This way, you’ll keep the outer layer crispy while ensuring the filling gets perfectly cooked.
