Mushroom Wellington is a vegetarian take on the classic Beef Wellington. The Hairy Bikers’ version features a savory mushroom and spinach filling, enhanced with herbs and creamy cheese, wrapped in flaky puff pastry. It’s a dish that combines rich flavors and textures for a satisfying meal.
Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.
Heat olive oil in a large skillet over medium heat. Add the onions and garlic and sauté for 5 minutes until softened. Stir in the mushrooms and cook until the moisture has evaporated about 8-10 minutes.
Add the spinach to the skillet and cook until wilted. Stir in the breadcrumbs, cream cheese, thyme, and season with salt and pepper. Mix well and let the filling cool slightly.
Roll out the puff pastry on a lightly floured surface. Place the mushroom mixture in the center, shaping it into a log. Fold the pastry over the filling, sealing the edges and trimming any excess pastry. Place the Wellington seam-side down on the prepared baking tray.
Brush the pastry with beaten egg to give it a golden, glossy finish. Use a knife to score a decorative pattern on top if desired.
Place the Wellington in the preheated oven and bake for 25-30 minutes, or until the pastry is golden brown and crisp.
Let the Wellington rest for a few minutes before slicing. Serve warm with your favorite sides.
