Create an impressive, hearty Vegan Mushroom Walnut Wellington, perfect as a centerpiece for your holiday meal. This recipe brings warmth and rich flavor to your table, making every day feel a bit like Sunday.
Heat olive oil in a large pan over medium heat. Sauté the onion until soft, about 5 minutes.
Add the minced garlic and thyme leaves. Cook for 1 minute until fragrant.
Add the chopped mushrooms to the pan. Cook until they release their liquid and the liquid has evaporated, about 10-12 minutes.
Stir in the soy sauce, Dijon mustard, toasted walnuts, and breadcrumbs. Season well with salt and pepper. Cook for 2 minutes, then remove from heat and let the mixture cool completely.
Lay the thawed puff pastry sheet on a baking sheet lined with parchment paper.
Spoon the cooled mushroom and walnut mixture down the center of the pastry, forming a log shape, leaving a 2-inch border on all sides.
Brush the edges of the pastry with plant-based milk.
Fold the longer sides of the pastry over the filling, overlapping them slightly. Press the edges firmly to seal. Trim any excess pastry.
Place the sealed Wellington seam-side down on the prepared baking sheet. Score the top lightly with a knife for decoration, being careful not to cut all the way through.
Brush the entire top surface of the Wellington with the remaining plant-based milk.
Bake for 30-35 minutes, or until the pastry is golden brown and puffed.
Let the Wellington rest for 10 minutes before slicing and serving.
Notes
Use a variety of mushrooms for the deepest flavor profile.
Toast your walnuts lightly before chopping to bring out their nutty taste.
Make the filling a day ahead and store it in the refrigerator to save time on the day you bake.
