Ingredients
- 1 tablespoon olive oil
- 1 yellow onion (medium, diced)
- 2 carrots (medium, diced)
- 2 celeries (diced)
- 3 clove garlic (minced)
- 1.5 cup brown lentils (rinsed)
- 4 cup vegetable broth (low-sodium)
- 2 tablespoon tomato paste
- 2 tablespoon all-purpose flour
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1 bay leaf
- 1 cup frozen peas
- 1 cup frozen corn
- 0.5 cup walnut (chopped)
- 1 tablespoon vegetarian Worcestershire sauce
- 3 sweet potatoes (large, peeled and cut into 1-inch chunks)
- 0.25 cup milk
- 2 tablespoon butter
- 0.25 teaspoon ground nutmeg
- 0.5 cup shredded cheddar cheese (shredded)
- 1.5 teaspoon salt
- 0.75 teaspoon black pepper
Instructions
- Preheat your oven to 375 degrees F (190 degrees C).
- Heat 1 tablespoon of olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the diced yellow onion, carrots, and celery, and cook for 5-7 minutes until softened. Stir in the minced garlic and cook for another 1 minute until fragrant.
- Add the rinsed brown lentils, low-sodium vegetable broth, tomato paste, all-purpose flour, dried thyme, dried rosemary, and bay leaf to the skillet. Bring to a boil, then reduce heat, cover, and simmer for 20-25 minutes, or until the lentils are tender.
- While the lentils are simmering, place the cut sweet potatoes in a large pot and cover with cold water. Bring to a boil and cook for 15-20 minutes, or until fork-tender. Drain well.
- Mash the cooked sweet potatoes with 1/4 cup milk, 2 tablespoons butter, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/4 teaspoon ground nutmeg until smooth and creamy. Set aside.
- Once the lentils are tender, stir in the frozen peas, frozen corn, chopped walnuts, and 1 tablespoon vegetarian Worcestershire sauce. Remove the bay leaf. Season the lentil mixture with 1 teaspoon salt and 1/2 teaspoon black pepper, adjusting to taste.
- Pour the lentil filling into an 8x8-inch or 9x13-inch baking dish (if using a Dutch oven, you can leave it in there). Spread the mashed sweet potato topping evenly over the lentil mixture. Sprinkle with shredded cheddar cheese, if using.
- Bake for 25-30 minutes, or until the filling is bubbly and the sweet potato topping is lightly browned. Let stand for 5 minutes before serving.
Notes
Leftovers store well in an airtight container in the refrigerator for up to 3 days. This dish also freezes beautifully; simply thaw and reheat in the oven or microwave. For a touch of freshness, garnish with fresh parsley before serving.
