Ingredients

• 1 cup green or brown lentils, rinsed and drained
• 2 cups vegetable broth (for cooking lentils)
• 8 oz cremini mushrooms, finely chopped
• 1 small onion, finely diced
• 3 cloves garlic, minced
• 1 cup walnuts, toasted and chopped
• 1 cup breadcrumbs (use gluten-free if desired)
• 2 tbsp ground flaxseed mixed with 6 tbsp water (flax egg)
• 2 tbsp soy sauce or tamari
• 2 tbsp olive oil, plus more for sautéing
• 1 tbsp tomato paste
• 1 tbsp fresh thyme, chopped (or 1 tsp dried thyme)
• 1 tbsp fresh sage, chopped (or 1 tsp dried sage)
• 1 tsp smoked paprika
• Salt and black pepper to taste
• 1 sheet vegan puff pastry (optional, for wrapping)
• 2 tbsp non-dairy milk (for brushing puff pastry)

Equipment

• Medium saucepan
• Large skillet or frying pan
• Mixing bowls
• Food processor or sharp knife (for chopping mushrooms and walnuts)
• Baking sheet or roasting pan
• Pastry brush (if using puff pastry)
• Measuring cups and spoons
• Oven
• Cooling rack (optional)

Instructions

1. Cook the lentils: In a medium saucepan, add lentils and vegetable broth. Bring to a boil, then reduce heat and simmer uncovered for 20-25 minutes until lentils are tender but not mushy. Drain any excess liquid and set aside to cool.
2. Sauté the vegetables: Heat 2 tablespoons olive oil in a large skillet over medium heat. Add diced onion and cook for 4-5 minutes until translucent. Add minced garlic and chopped mushrooms, cooking for another 8-10 minutes until mushrooms release their moisture and start to brown. Stir in soy sauce, tomato paste, thyme, sage, smoked paprika, salt, and pepper. Cook for 2 more minutes. Remove from heat and let cool slightly.
3. Prepare the flax egg: In a small bowl, combine ground flaxseed and water. Stir well and let sit for 5-10 minutes until it thickens.
4. Mix the roast base: In a large mixing bowl, combine cooked lentils, sautéed mushroom mixture, toasted walnuts, breadcrumbs, and flax egg. Mix well until the mixture holds together when pressed. If too wet, add more breadcrumbs; if too dry, add a splash of vegetable broth or olive oil.
5. Shape the roast: On a parchment-lined baking sheet, form the mixture into a loaf shape about 8-9 inches long and 4 inches wide. If using puff pastry, roll out the pastry sheet and wrap it around the loaf, sealing edges with a little water. Brush the top with non-dairy milk for a golden finish.
6. Bake: Preheat oven to 375°F (190°C). Bake the roast uncovered (or wrapped in pastry) for 35-40 minutes, until golden and firm to the touch. If wrapped in pastry, bake until the pastry is crisp and browned.
7. Rest and serve: Remove from oven and let the roast rest for 10 minutes before slicing. This helps it set and makes slicing easier.

Tips & Variations

“For an extra burst of flavor, add a handful of dried cranberries or chopped fresh herbs like rosemary to the mixture before baking.”

• Nut-free option: Substitute walnuts with sunflower seeds or omit nuts entirely and add extra breadcrumbs for texture.
• Gluten-free: Use gluten-free breadcrumbs and skip the puff pastry or use a gluten-free alternative.
• Stuffed roast: Create a pocket inside the shaped loaf and fill with sautéed spinach and vegan cheese for a delightful surprise.
• Make it smoky: Add a teaspoon of liquid smoke or smoked salt for a deeper, smoky flavor.
• Advance prep: Prepare the mixture and shape the roast a day ahead. Wrap tightly and refrigerate until ready to bake.
