Ingredients
- 30 ml (2 tablespoons) olive oil
- 1 medium onion (approximately 150g), finely chopped
- 700g (3 cups) mixed mushrooms (cremini, button, or a blend), chopped
- 150g (1 ½ cups) fresh spinach, chopped
- 190g (1 cup) cooked green or brown lentils
- 2 cloves garlic, minced
- 5g (1 tablespoon) fresh thyme, finely chopped
- 5g (1 tablespoon) fresh rosemary, finely chopped
- 5 ml (1 teaspoon) soy sauce or tamari
- 0.5g (1/4 teaspoon) ground black pepper, or to taste
- 0.5g (1/4 teaspoon) ground nutmeg
- 60g (1/2 cup) plain breadcrumbs
- 15 ml (1 tablespoon) Dijon mustard
- 2 sheets (approximately 450-500g total) all-butter puff pastry, thawed according to package instructions
- 1 large egg, beaten (for egg wash)
- 15g (1 tablespoon) all-purpose flour, for dusting
- Optional: Fresh parsley or thyme sprigs, for garnish
- Optional: Rich mushroom or vegetable gravy, for serving
Instructions
- PREPARE THE FILLING. Heat 30 ml (2 tablespoons) of olive oil in a large, heavy-bottomed pan or skillet over medium heat. Add the finely chopped onion and sauté for 3 to 4 minutes until it becomes translucent and softened. Incorporate the minced garlic and cook for an additional 1 to 2 minutes, stirring constantly until fragrant, being careful not to burn it.
- COOK THE MUSHROOMS AND SPINACH. Add the chopped mushrooms to the pan. Cook for 7 to 8 minutes, stirring occasionally, allowing them to release their moisture and achieve a lovely golden-brown color. This step is crucial for developing deep umami flavor. Next, stir in the chopped fresh spinach and continue cooking for 2 to 3 minutes until it has fully wilted. If there is any excess liquid in the pan, continue to cook until it evaporates, ensuring the filling is not watery.
- SEASON AND BIND THE FILLING. Stir in the 5 ml (1 teaspoon) of soy sauce, 0.5g (1/4 teaspoon) ground black pepper, 0.5g (1/4 teaspoon) ground nutmeg, 5g (1 tablespoon) fresh thyme, and 5g (1 tablespoon) fresh rosemary. Mix well to combine all the aromatics and spices. Taste the mixture and adjust seasonings as desired. Add the 190g (1 cup) of cooked lentils to the pan and gently fold them into the vegetable mixture. Finally, stir in the 60g (1/2 cup) of breadcrumbs and 15 ml (1 tablespoon) of Dijon mustard. These ingredients will help absorb any remaining moisture and bind the filling together, making it easier to shape. Remove the pan from the heat and allow the filling to cool slightly. For best results, let it cool completely in the refrigerator, which can make assembly much easier.
- PREPARE THE PUFF PASTRY. Lightly dust a clean work surface with flour. Carefully unroll one sheet of thawed puff pastry. If the sheets are rectangular, place one with the long side facing you. If they are square, you may need to gently roll them into a roughly rectangular shape, aiming for dimensions around 25×35 cm (10×14 inches). Repeat with the second sheet. You can either place the two pastry sheets side by side, overlapping by about 2 cm (3/4 inch), and press them together firmly to form one large sheet, or keep them separate to create two smaller Wellingtons. For a single large Wellington, ensure the seam is well sealed.
- ASSEMBLE THE WELLINGTON. Spoon the cooled vegetarian filling down the center of one of the prepared puff pastry sheets, forming a log shape. Leave a border of at least 5 cm (2 inches) on all sides. Avoid overfilling, as this can make sealing difficult. Gently bring one long edge of the pastry over the filling, then bring the other long edge over to meet it, completely encasing the filling. Press the edges together firmly to seal the Wellington, ensuring there are no gaps. Trim any excess pastry if necessary. Carefully tuck in and crimp the short ends to seal them completely. For a decorative finish, you can use the back of a fork to press down along the seams.
- EGG WASH AND DECORATE. Carefully transfer the sealed Wellington, seam-side down, onto a baking tray lined with parchment paper. Using a pastry brush, evenly coat the entire surface of the puff pastry with the beaten egg wash. This will give it a beautiful golden sheen during baking. If desired, you can use any pastry trimmings to create decorative cut-outs (such as leaves or braids) and attach them to the top of the Wellington with more egg wash. Using a sharp knife, make a few shallow slits across the top of the pastry to allow steam to escape, which helps prevent the pastry from puffing up unevenly.
- BAKE THE WELLINGTON. Preheat your oven to 200°C (400°F). Bake the Vegetarian Wellington for 30 to 40 minutes, or until the puff pastry is deeply golden brown, puffed, and crisp. The exact baking time may vary depending on your oven, so keep an eye on it to prevent burning. If the pastry starts to brown too quickly, you can loosely tent it with aluminum foil.
- REST AND SERVE. Once baked, remove the Wellington from the oven and let it rest on the baking tray for 5-10 minutes before slicing. This resting period allows the filling to set and prevents it from crumbling when cut. Carefully transfer the Wellington to a serving platter, garnish with fresh herbs if using, and serve warm with a side of rich mushroom or vegetable gravy.

Tools You’ll Need
- Large skillet or pan
- Sharp chef's knife
- Cutting board
- Measuring cups and spoons
- Pastry brush
- Baking tray
- Parchment paper
- Rolling pin (optional, if shaping pastry)
- Cooling rack (optional)
Essential Success Tips
- Ensure the filling is completely cool, and ideally chilled, before assembling. A warm filling will make the puff pastry greasy and difficult to work with and seal properly.
- Do not overfill the pastry; leave a generous border on all sides to ensure a secure seal that will hold during baking.
- Press the pastry seams together very firmly to prevent any of the delicious filling from leaking out while baking.
- Make several shallow slits across the top of the pastry. This is crucial for allowing steam to escape, which prevents a soggy bottom and promotes even puffing and a crisp crust.
- Monitor baking closely as oven temperatures can vary. If the pastry begins to brown too quickly, loosely tent it with aluminum foil to prevent burning while the interior cooks through.
Professional Cooking Secrets
- For an extra layer of savory depth and to act as a moisture barrier, consider spreading a thin layer of vegetarian mushroom pâté or a dairy-free cream cheese mixture on the pastry before adding the filling.
- To further ensure a crisp bottom crust, brush the interior of the bottom puff pastry sheet lightly with an egg white before spooning on the filling. This creates a protective barrier.
- Always opt for high-quality, all-butter puff pastry for the best flavor and flakiest texture. While store-bought frozen pastry is convenient, the quality significantly impacts the final result.

Notes
- Storage: Leftover Vegetarian Wellington can be stored in an airtight container in the refrigerator for up to 3 days. For best results in reheating, gently warm slices in a preheated oven until crisp.
- Freezing: The assembled, unbaked Wellington can be frozen for up to 1 month. Wrap it tightly in plastic wrap, then foil, before freezing. Bake from frozen, adding approximately 15-20 minutes to the baking time, or until deeply golden and heated through.
- Variations: Feel free to experiment with other complementary vegetables in the filling, such as roasted butternut squash, sweet potatoes, or sautéed leeks. For a richer, non-vegan option, fold in some crumbled feta or goat cheese into the cooled filling.
Frequently Asked Questions
Can I make this Vegetarian Wellington ahead of time?
