Ingredients
Vegan Wellington With Mushrooms Lentils and Spinach Recipe – Vegan Kitchen Wizard
For the Mushroom and Lentil Filling
- 2 tablespoons olive oil
- 1 medium yellow onion, finely chopped
- 3 garlic cloves, minced
- 1 pound cremini or button mushrooms, finely chopped
- 1 cup cooked brown or green lentils, drained well
- 2 cups fresh spinach, roughly chopped
- ½ cup walnuts, finely chopped
- 2 tablespoons tomato paste
- 1 tablespoon soy sauce or tamari
- 1 tablespoon Dijon mustard
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary
- ½ teaspoon smoked paprika
- ½ teaspoon salt, or to taste
- ¼ teaspoon black pepper
- ½ cup breadcrumbs (check that they’re vegan)
For the Pastry
- 1 sheet vegan puff pastry, thawed according to package instructions (about 10–14 ounces)
- 2 tablespoons unsweetened plant-based milk, for brushing
- 1 teaspoon maple syrup, optional, for a deeper golden finish
- 1 tablespoon all-purpose flour, for dusting
- Sesame seeds or fresh rosemary, optional garnish
Important: Check the puff pastry label to make sure it contains no butter, milk, or other animal-derived ingredients.
Instructions
Step 1: Prepare the Vegetables

Finely chop the mushrooms and onion. Mince the garlic and roughly chop the spinach.
If using canned lentils, drain and rinse them thoroughly. Pat them dry with a clean kitchen towel to remove excess moisture.
Step 2: Cook the Mushroom Filling
Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook for 4–5 minutes until softened.
Stir in the garlic and cook for another 30 seconds. Add the mushrooms and cook for 10–12 minutes, stirring occasionally, until their moisture has evaporated and they become nicely browned.
This step is important: a dry filling helps prevent the puff pastry from becoming soggy.
Step 3: Add Lentils, Spinach, and Seasonings

Add the cooked lentils, spinach, walnuts, tomato paste, soy sauce, Dijon mustard, thyme, rosemary, smoked paprika, salt, and black pepper.
Stir well and cook for 3–4 minutes, until the spinach wilts and everything is combined.
Use a fork or potato masher to lightly mash some of the lentils. This helps the filling hold together while leaving plenty of texture.
Step 4: Add Breadcrumbs and Cool the Filling

Remove the skillet from the heat. Stir in the breadcrumbs until the mixture becomes thick and holds together when pressed.
Transfer the filling to a shallow bowl or tray and spread it out to cool completely. Refrigerate for about 20 minutes if needed.
Important: Never wrap warm filling in puff pastry. The heat can soften the pastry and make it difficult to handle.
Step 5: Prepare the Puff Pastry

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Lightly dust your work surface with flour and unfold the thawed puff pastry. Gently roll it into a rectangle approximately 10 × 14 inches, following the package’s directions.
Keep the pastry cool but flexible. If it becomes too soft or sticky, refrigerate it for a few minutes.
Step 6: Shape the Wellington

Spoon the cooled mushroom and lentil mixture onto the center of the pastry, shaping it into a compact log about 9 inches long.
Leave enough pastry around the filling to fold and seal the Wellington. Avoid overfilling, as this can cause the pastry to split during baking.
Step 7: Wrap and Seal

Fold one long side of the pastry over the filling, then fold the other side over it.
Brush the pastry edges lightly with plant-based milk and press them together to seal. Fold the ends underneath the Wellington and pinch gently to close.
Carefully turn the Wellington seam-side down onto the prepared baking sheet.
Step 8: Decorate and Brush

Use any leftover pastry to cut decorative leaves or strips. Arrange them on top of the Wellington.
Mix the plant-based milk with the optional maple syrup. Brush the entire pastry lightly with this mixture.
Use a sharp knife to make a few shallow slits on top so steam can escape. Avoid cutting deeply into the filling.
Step 9: Bake Until Golden

Bake for 35–45 minutes, or until the pastry is puffed, crisp, and deep golden brown.
If the top browns too quickly, loosely cover it with foil for the remaining baking time.
Remove from the oven and let the Wellington rest for 10–15 minutes before slicing. This helps the filling settle and makes cleaner slices.
Step 10: Slice and Serve

Serve warm with vegan gravy, roasted vegetables, cranberry sauce, or your favorite holiday sides.
The crisp pastry, savory mushroom filling, hearty lentils, and crunchy walnuts make every bite delicious!
Tips for the Best Vegan Wellington
- Cook mushrooms thoroughly: Mushrooms release a lot of water. Cook until the skillet is almost dry.
- Cool the filling completely: Warm filling can soften the pastry and create a soggy bottom.
- Use vegan puff pastry: Some brands contain butter, so always check the ingredients.
- Don’t overfill: A compact filling log is easier to wrap and bake evenly.
- Keep pastry cold: Cold puff pastry produces better flaky layers.
- Seal the edges well: This prevents the filling from escaping during baking.
- Rest before slicing: Allowing the Wellington to rest helps the slices hold their shape.
Easy Recipe Variations
1. Vegan Wellington with Chestnuts
Replace half the walnuts with ½ cup finely chopped cooked chestnuts for a festive holiday flavor.
2. Spinach and Sun-Dried Tomato Wellington

3. Sweet Potato and Lentil Wellington
Replace half the mushrooms with 1 cup cooked mashed sweet potato. Make sure the mixture is not too wet.
4. Vegan Wellington with Cranberries
Add ¼ cup dried cranberries for a sweet and savory holiday filling.
5. Gluten-Free Vegan Wellington
Use certified gluten-free vegan puff pastry and gluten-free breadcrumbs. Check all sauces and seasonings for gluten as well.

Storage and Reheating
Refrigerator: Allow leftovers to cool and refrigerate in an airtight container within 2 hours. Store for up to 3 days.
Freezer: For best pastry texture, freeze the assembled unbaked Wellington before baking. Wrap it tightly and freeze for up to 1 month. Bake from frozen at 400°F, allowing extra time and checking that the pastry is fully baked.
Reheating: Place leftover slices on a baking sheet and warm at 350°F for 10–15 minutes, until heated through. Avoid microwaving if you want to keep the pastry crisp.
Make Ahead: Prepare the mushroom and lentil filling up to 2 days ahead. Store it covered in the refrigerator. Assemble the Wellington shortly before baking for the best flaky pastry.
