Instructions

1. Step 1: Preheat oven to 425°F. Toss 2 medium peeled and cubed sweet potatoes with 1 tbsp olive oil and 1/4 tsp salt on a rimmed baking sheet. Roast for 25-30 minutes, turning halfway, until tender and edges caramelize.
2. Step 2: While sweet potatoes roast, heat 2 tbsp olive oil in a large pot over medium heat. Add 1 diced medium yellow onion and sauté for 5 minutes until translucent.
3. Step 3: Add 3 minced garlic cloves, 1 tsp ground cumin, 1 tsp ground coriander, and 1/2 tsp smoked paprika to the pot. Cook, stirring, for 1 minute until fragrant.
4. Step 4: Stir in 1 cup dry brown lentils, 1 can (14 oz) diced tomatoes, and 4 cups vegetable broth. Season with 1 tsp salt and 1/2 tsp black pepper. Bring to a boil, then reduce heat to low and simmer uncovered for 25-30 minutes until lentils are tender and stew thickens.
5. Step 5: Once the stew is ready, stir in the roasted sweet potatoes, gently folding to combine and warm through for 2 minutes.
