Ingredients
Servings
6
- 2 cups dried brown lentils, rinsed and drained
- 4 cups vegetable broth
- 1 tablespoon olive oil
- 1 large onion, finely chopped
- 3 cloves garlic, minced
- 2 medium carrots, diced
- 2 celery stalks, diced
- 1 cup mushrooms, finely chopped
- 1 tablespoon tomato paste
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1 teaspoon smoked paprika
- Salt and freshly ground black pepper, to taste
- 3 large sweet potatoes (about 2 pounds), peeled and chopped
- 1/4 cup unsweetened plant-based milk (such as almond or oat milk)
- 2 tablespoons olive oil or vegan butter
- 2 tablespoons nutritional yeast (optional, for savory flavor)
- Fresh parsley, chopped (for garnish)
Instructions
-
Preheat oven to 375°F (190°C).
-
In a large pot, combine rinsed brown lentils and vegetable broth. Bring to boil, then reduce heat and simmer uncovered for 25–30 minutes, or until lentils are tender but not mushy. Drain any excess liquid and set lentils aside.
-
Meanwhile, boil sweet potatoes in a medium pot until tender, about 15–20 minutes. Drain and mash with plant-based milk, olive oil or vegan butter, nutritional yeast if using, and salt and pepper to taste. Set aside.
-
Heat 1 tablespoon olive oil in a large skillet over medium heat. Sauté onion, garlic, carrots, celery, and mushrooms for 8–10 minutes, until softened and fragrant.
-
Add tomato paste, dried thyme, rosemary, and smoked paprika to the skillet. Cook for 1–2 minutes to deepen flavors.
-
Stir cooked lentils into the vegetable mixture. Season with salt and pepper. Cook for an additional 3–5 minutes to heat through and blend flavors.
-
Transfer lentil and vegetable mixture evenly into a 9x13 inch (23x33 cm) oven-safe baking dish.
-
Spread mashed sweet potatoes evenly over the lentil mixture. Use a spatula to smooth, and optionally create texture with a fork for a crispier top crust.
-
Bake uncovered for 20–25 minutes, until the sweet potato topping is golden and heated through.
-
Remove from the oven and let rest for 5 minutes before serving.
-
Garnish with fresh chopped parsley and serve warm.
