This Vegan Wellington is a stunning plant-based centerpiece with a golden, flaky pastry wrapped around a rich mushroom, lentil, and walnut filling.
Earthy mushrooms, savory herbs, garlic, and toasted walnuts create layers of flavor and satisfying texture.
It’s elegant enough for holidays yet simple enough to make for a special Sunday dinner.
Can This Vegan Wellington Support Weight Loss Goals?
It can fit into a balanced eating pattern when enjoyed in a reasonable portion. Lentils provide plant protein and fiber, while mushrooms and vegetables add volume and nutrients. The pastry and walnuts contribute more concentrated calories and fat, so pairing a moderate slice with plenty of vegetables or salad creates a balanced meal.
Does Vegan Wellington Fit a High-Protein Lifestyle?
Yes, the lentils and walnuts make this more protein-rich than many pastry-based vegan dishes. A serving provides approximately 14 g of plant protein, while mushrooms contribute additional nutrients and texture. However, the pastry adds carbohydrates, so the dish isn’t particularly low-carb. For an even higher-protein version, increase the lentils or add finely crumbled tofu to the filling.

Common Mistakes to Avoid

- Wrapping warm filling — Cool the filling before adding pastry to prevent sogginess.
- Overfilling the pastry — Leave enough room to seal the Wellington securely.
- Skipping pastry vents — Small vents allow steam to escape and help keep the crust crisp.
Required Equipment
- Large skillet — Gives mushrooms enough room to release moisture and brown.
- Food processor — Quickly chops walnuts and vegetables.
- Baking sheet — Provides a flat surface for even pastry browning.
- Parchment paper — Makes transferring and cleanup easier.
- Pastry brush — Creates a golden finish with plant milk.

📝 Ingredients
Filling
- 1 tbsp olive oil
- 1 medium onion, finely diced
- 3 cloves garlic, minced
- 400 g mushrooms, finely chopped
- 1 cup cooked brown or green lentils, drained
- ½ cup walnuts, finely chopped
- 1 tbsp tomato paste
- 1 tbsp soy sauce or tamari
- 1 tbsp Dijon mustard
- 1 tsp dried thyme
- ½ tsp dried rosemary
- ½ tsp smoked paprika
- ½ tsp salt
- ¼ tsp black pepper
- ½ cup breadcrumbs
- 2 tbsp fresh parsley, chopped
Pastry
- 1 sheet vegan puff pastry, thawed
- 2 tbsp unsweetened plant milk
- 1 tsp sesame seeds, optional
Ingredient note: Make sure the puff pastry is vegan, as some varieties contain butter. Use tamari for a gluten-free option, but check that the pastry and breadcrumbs are also gluten-free.
Directions
- Preheat: Heat oven to 200°C / 400°F. Line a baking sheet with parchment paper.
- Cook onion: Heat olive oil in a large skillet over medium heat. Add onion and cook for 4–5 minutes, until softened.
- Add garlic: Stir in garlic and cook for 30 seconds.
- Cook mushrooms: Add chopped mushrooms and cook over medium-high heat for 8–12 minutes, stirring frequently. Continue until the mushrooms release their liquid and the pan becomes mostly dry.
- Build filling: Add lentils, walnuts, tomato paste, soy sauce, Dijon mustard, thyme, rosemary, smoked paprika, salt, and pepper.
- Cook: Stir over medium heat for 3–4 minutes until the mixture is thick and cohesive. Remove from heat.
- Add breadcrumbs: Stir in breadcrumbs and parsley. The filling should hold together when pressed. Cool for 15–20 minutes.
- Prepare pastry: Unroll the puff pastry onto parchment paper. Spoon the filling into a compact log down the center, leaving several centimeters of pastry around the edges.
- Wrap: Fold the pastry over the filling and seal the edges firmly. Place seam-side down on the baking sheet.
- Decorate: Cut a few small vents across the top. Brush lightly with plant milk and sprinkle with sesame seeds if desired.
- Bake: Bake at 200°C/400°F for 25–30 minutes, until the pastry is puffed and deeply golden.
- Rest: Let the Wellington rest for 10–15 minutes before slicing. The filling should be firm enough to hold its shape.
High-protein tip: Add an extra ½ cup cooked lentils or 150 g crumbled firm tofu to the filling for a higher-protein Wellington.
