Cook the Lentils:
Combine the lentils with 3 cups of water in a medium saucepan. Bring to a boil, then simmer for 25-30 minutes until tender. Drain and set aside.
Prepare the Filling:
Heat olive oil in a large skillet. Add onion and garlic, sauté for 5 minutes until translucent.
Stir in carrots, celery, and mushrooms. Cook for 7-8 minutes until softened.
Add tomato paste, thyme, rosemary, and smoked paprika. Mix well.
Stir in lentils and vegetable broth. Simmer for 10 minutes.
Add peas and corn. Cook for 5 more minutes. Season with salt and pepper.
Make the Mashed Potatoes:
Boil potatoes until tender (15-20 minutes). Drain and mash with plant-based milk and vegan butter. Season with salt and pepper.
Assemble the Shepherd’s Pie:
Preheat oven to 400°F (200°C).
Spread lentil filling evenly in a baking dish.
Top with mashed potatoes, using a fork to create ridges.
Sprinkle with paprika (optional).
Bake:
Bake for 20-25 minutes, or until golden and crispy.
For extra crisp, broil for 2-3 minutes, watching carefully.
Serve:
Garnish with fresh parsley. Serve hot and enjoy!
