Ingredients

Scale

Pastry:

  • 1 sheet frozen vegan puff pastry

Mushroom Filling:

  • 1 pound white mushrooms (454 grams)
  • 3½ tablespoons olive oil or avocado oil, divided (53 ml)
  • 2 cups chopped red onion (256 grams)
  • 3 medium cloves garlic, minced
  • 2 tablespoons balsamic vinegar (30 ml)
  • ½ cup chopped home-cooked or canned water chestnuts (optional) (70 grams)
  • ½ tablespoon chopped fresh thyme or ½ teaspoon dried thyme
  • ½ tablespoon chopped fresh sage or ½ teaspoon dried sage
  • ¾ teaspoon salt (plus more to taste)
  • ¼ teaspoon black pepper (plus more to taste)
  • 4 ounces fresh baby spinach, roughly chopped (113 grams)
  • ½ tablespoon unsweetened, plain non-dairy milk

Instructions

  1. Preheat Oven: Set your oven to 375°F (190°C) and line a baking sheet with parchment paper to prepare for baking.
  2. Thaw Pastry: Remove the puff pastry sheet from the freezer and allow it to thaw while you prepare the filling.
  3. Process Mushrooms: Place mushrooms in a food processor and pulse 10-11 times until crumbly but not pureed, keeping some texture.
  4. Sauté Onions and Garlic: Heat 2 tablespoons of oil in a large skillet over medium-high heat. Add red onions and cook for 3-4 minutes until softened, then lower heat to medium and add garlic, cooking for an additional 2 minutes to build flavor.
  5. Cook Mushrooms: Add processed mushrooms and balsamic vinegar to the skillet. Continue cooking while stirring occasionally until most mushroom moisture evaporates, approximately 10-12 minutes.
  6. Add Herbs and Spinach: Push mushroom mixture aside, add 1 tablespoon oil to the center of skillet. Stir in water chestnuts (if using), thyme, sage, salt, and pepper, and sauté for about 1 minute until fragrant. Add spinach and cook until wilted before mixing thoroughly with mushroom mixture. Adjust salt and pepper to taste and turn off heat.
  7. Roll Puff Pastry: On a lightly floured surface, roll out the thawed puff pastry so it extends 1-2 inches beyond original size on all sides. Transfer carefully onto prepared baking sheet.
  8. Assemble Wellington: Place mushroom filling in the center of the pastry, shaping into a loaf. Fold long sides up to meet in the middle and pinch to seal. Trim short ends to leave about 1½ inches of pastry on each side, fold those ends over the top, then gently flip the loaf so the seam is underneath. Use trimmed pastry pieces to create decorative patterns if desired.
  9. Score Pastry: Using a sharp knife, make two rows of 1-inch diagonal slits across the top of the Wellington and pierce small holes on each side to allow steam to escape.
  10. Brush with Milk and Oil: Mix remaining ½ tablespoon oil with non-dairy milk and brush lightly all over the pastry surface for an even golden finish.
  11. Bake: Bake in the preheated oven for 40-45 minutes, rotating the baking sheet halfway through at about the 20-minute mark for even browning. Remove when pastry is golden brown and cooked through.
  12. Rest and Serve: Let the Wellington rest for 10 minutes before slicing into thick portions for serving.

Notes

  • Using fresh herbs like thyme and sage enhances the flavor but dried herbs can be substituted if fresh are unavailable.
  • Water chestnuts provide a crunchy texture but are optional and can be omitted for preferences or allergies.
  • Letting the puff pastry thaw properly prevents cracking or tearing when rolling.
  • The mushroom mixture should be cooked until most liquid evaporates to avoid soggy pastry.
  • Decorative pastry trims can add an elegant touch to your Wellington; get creative!
  • Allowing the Wellington to rest ensures slices hold together better when served.
  • If unable to find vegan puff pastry, check ingredients carefully as some brands contain butter or other animal products.
