16 - 1 sheet vegan puff pastry (approximately 11 ounces, thawed if frozen)
17 - 2 tablespoons non-dairy milk for brushing
18 - 1 teaspoon sesame seeds or poppy seeds (optional, for topping)
# Directions:
01 - Preheat oven to 400°F and line a baking tray with parchment paper.
02 - Heat olive oil in a large skillet over medium heat. Add onion and cook for 5 minutes until softened.
03 - Add garlic, mushrooms, carrot, and celery to the skillet. Cook, stirring frequently, for 10 to 12 minutes until mushrooms release liquid and mixture is dry.
04 - Incorporate thyme, rosemary, and chopped chestnuts. Cook for 2 minutes, stirring to combine.
05 - Add spinach leaves, stirring until wilted. Mix in soy sauce, nutritional yeast, Dijon mustard, and breadcrumbs. Season generously with salt and black pepper. Remove from heat and allow mixture to cool for 10 minutes.
06 - Roll out the thawed puff pastry sheet on a lightly floured surface. Position mushroom filling in the center, forming a log shape and leaving a 1-inch border.
07 - Enclose filling by folding the pastry over, sealing edges tightly. Place seam-side down on the prepared tray and score the top with a sharp knife.
08 - Brush the surface with non-dairy milk and sprinkle with sesame or poppy seeds if desired.
09 - Transfer to oven and bake for 35 to 40 minutes until the pastry is crisp and golden brown.
10 - Allow Wellington to cool for 10 minutes before slicing. Serve warm, accompanied by vegan gravy or roasted vegetables if desired.
