Cooking Steps

1. Preheat the oven to 200 °C (400 °F) and position the oven rack in the center. This allows for even heat distribution while cooking the Wellington.

2. Prepare a clean and dry surface for the mise en place. Verify all ingredients are chopped and ready for use. Dust the surface lightly with flour to prevent the pastry from sticking later.

3. In a large skillet, heat 2 tablespoons of olive oil over medium heat (around 175 °C/350 °F).

4. Add 1 medium diced onion to the skillet and sauté for 3–4 minutes until translucent and aromatic.

5. Stir in 2 cloves of minced garlic and continue cooking for an additional 1 minute, allowing the garlic to become fragrant but not burnt.

6. Increase the heat slightly to medium-high, then add 2 cups of finely chopped mushrooms and sauté for 7–10 minutes, stirring occasionally, until the mushrooms release moisture and begin to brown. The mixture should be relatively dry.

7. Lower the heat back to medium and add 1 cup of chopped walnuts, 1 tablespoon of chopped fresh thyme, 1 tablespoon of chopped fresh parsley, 1 tablespoon of soy sauce, 1 teaspoon of Dijon mustard, ½ teaspoon of salt, and ¼ teaspoon of black pepper. Mix thoroughly, cooking for an additional 2–3 minutes.

Remove from heat and allow the filling to cool slightly.

8. Roll out the puff pastry on the floured surface to a rectangle, making sure it’s large enough to envelop the filling (approximately 30 cm x 40 cm or 12 in x 16 in).

9. Place the cooled mushroom-walnut mixture in the center of the puff pastry, shaping it into a log-like form, leaving space on each side for folding.

10. Fold the sides of the pastry over the filling to encase it, sealing the edges by pressing them together. If using, brush the top with a beaten egg for a golden finish.

11. Transfer the wrapped Wellington onto a baking sheet lined with parchment paper.

12. Bake in the preheated oven on the center rack for 25–30 minutes, or until the pastry is golden brown and flaky. Check the pastry for a rich golden color and a crisp outer texture.

13. Remove the Wellington from the oven and let it rest for 5–10 minutes. This allows for easier slicing and helps retain moisture within the filling during carryover cooking.

14. Slice the Mushroom-Walnut Wellington and serve while warm, enjoying the blend of flavors and textures.

Variations

  • Spinach and Feta Wellington: Substitute the mushroom and walnut filling with 2 cups (300 g) of chopped spinach and 200 g (7 oz) of crumbled feta cheese for a Mediterranean twist.
  • Vegan Lentil Wellington: Replace the filling with 2 cups (400 g) of cooked lentils, mixed with 1 cup (150 g) of diced carrots and 1 tablespoon of nutritional yeast for a protein-packed vegan option.
  • Butternut Squash and Sage Wellington: Use 2 cups (300 g) of roasted and mashed butternut squash and 1 tablespoon of fresh sage for a seasonal and earthy flavor profile.
  • Gluten-Free Quinoa Wellington: Swap regular puff pastry for gluten-free pastry and use 1 cup (170 g) of cooked quinoa mixed with vegetables like bell peppers and zucchini for a hearty gluten-free version.
