Lentil and Mushroom Wellington Recipe: A Vegan Twist on the Classic

If you’re a vegan or simply want to indulge in a delightful veggie main course for Christmas, I can’t recommend anything more fitting than the exquisite Lentil and Mushroom Wellington.

This vegan beef Wellington is a golden-brown, flaky puff pastry encasing a rich and hearty filling of lentils and mushrooms, seasoned to perfection with a symphony of herbs and spices. It’s a perfect Beef Wellington alternative. Believe me, the layers of flavors are so complex and satisfying that you won’t miss the traditional meat-centric dishes like the baked stuffed chicken for a moment.

Ingredients
  

  • 1 cup green or brown lentils cooked
  • 2 cups mushrooms a mix of cremini and shiitake works well, finely chopped
  • 1 onion finely chopped
  • 3 cloves garlic minced
  • 1 carrot grated
  • 1 celery stalk finely chopped
  • 1/2 cup walnuts chopped
  • 1/4 cup fresh parsley chopped
  • 1 tsp dried thyme
  • Salt and pepper to taste
  • 2 tbsp olive oil
  • 1 sheet puff pastry thawed if frozen
  • 1 tbsp Dijon mustard
  • 1 tbsp ground flaxseed mixed with 3 tablespoons water

Instructions
 

  • Preheat the oven to 375°F (190°C).
  • In a large pan, heat olive oil over medium heat. Add onions and garlic, sauté until softened.
  • Add mushrooms, carrot, and celery to the pan. Cook until the mushrooms release their moisture and the vegetables are tender.
  • Stir in cooked lentils, walnuts, thyme, salt, and pepper. Cook for an additional 5-7 minutes, allowing the flavors to meld. Remove from heat and let it cool.
  • Roll out the puff pastry on a lightly floured surface. Spread Dijon mustard in the center, leaving about 2 inches on each side.
  • Spoon the lentil and mushroom mixture onto the mustard-covered area.
  • Fold the puff pastry over the filling, sealing the edges. You can crimp the edges with a fork to create a decorative pattern.
  • Mix ground flaxseed with water to make a flaxseed egg. Brush the pastry with the flaxseed egg for a golden finish.
  • Place the Wellington on a baking sheet and bake in the preheated oven for 25-30 minutes or until the pastry is golden brown and crispy.
  • Allow it to cool for a few minutes before slicing. Serve with your favorite sides.
