Ingredients for One-Pot Sweet Potato and Black Lentil Dahl

Instructions

In a large heavy-bottomed pot or deep skillet, heat the coconut oil over medium heat.
Add the mustard seeds and cumin seeds; toast until they begin to pop, about 1 minute.
Add the chopped onion and sauté until soft and translucent, about 5 minutes.
Stir in the minced garlic and grated ginger; cook for 1 minute until fragrant.
Add turmeric, ground coriander, garam masala, chili powder, and cinnamon. Stir well to evenly coat the onion mixture and cook the spices for 1 minute.
Add the diced sweet potatoes and rinsed black lentils to the pot. Stir to combine with the spice mixture.
Pour in the diced tomatoes with their juices and vegetable broth. Stir well and bring the mixture to a boil.
Once boiling, reduce heat to low, cover, and simmer for 35-40 minutes, or until lentils are tender and sweet potatoes are cooked through. Stir occasionally to prevent sticking and add water or broth if needed.
Season with salt to taste.
Turn off the heat and stir in the lime juice.
Serve the dahl hot, garnished with fresh chopped cilantro. Enjoy on its own or with steamed rice or gluten-free flatbread.
