Add the oil to a large pot or dutch oven over medium heat.
2 Tablespoons Oil
Once the oil is hot, add the onion, garlic and coriander seeds. Cook, stirring frequently, until the onions have softened and the mixture is fragrant.
½ Cup Yellow Onion, 1 Tablespoon Coriander Seeds, 2 cloves Garlic
Reduce the heat to medium low. Add the sweet potatoes, lentils, tomato, water, coconut milk, turmeric, ginger, and cayenne pepper to the pot. Stir well and bring to a simmer.
3 Cups Sweet Potatoes, 1 Cup Dried Lentils, 1 Cup Tomato, 1 Cup Water, 1 Tablespoon Turmeric, 2 teaspoons Ground Ginger, 1 teaspoon Cayenne Pepper, 13.5 ounce Coconut Milk
Once the curry is simmering, cover it and allow it to gently simmer for 30-40 minutes. The potatoes should be almost fork tender.
Add in the spinach and allow it to wilt. This should take 2-3 minutes.
2 Cups Baby Spinach
Season with salt and pepper to taste and serve. We like to serve ours over rice.
