Spiced Sweet Potato and Lentil Soup is comfort in a bowl during chilly months. You get a velvety mix of sweet potatoes and lentils simmered together with warming spices for a meal that is deeply satisfying and nutritious. It is a soup that keeps you fueled for hours, and is easy enough to throw together on a busy evening.
I first made a version of this soup when my family wanted something hearty but I was short on time. The spices make your kitchen smell incredible and we have never gotten bored of this nourishing bowl.
Ingredients
- Sweet potatoes: Give this soup a natural creaminess and sweetness Look for firm unblemished roots with deep orange flesh for best flavor
- Dried red lentils: Break down quickly and cook fast Choose the brightest ones for freshness
- Onion, carrots, and celery: Create a savory base for the soup Use firm veggies free of soft spots
- Garlic and ginger: Add aromatic warmth I highly recommend using fresh and grating the ginger for best results
- Vegetable broth: Gives depth Use a low sodium and clear variety when possible
- Coconut milk: Supplies richness and silkiness to the broth Full fat makes a lush texture but light coconut milk works too
- Olive oil: For sautéing Use extra virgin if you can for heart healthy flavor
- Cumin, coriander, smoked paprika, turmeric, cinnamon, and cayenne: These spices build deep flavor layers Seek out high quality ground spices that are not past their prime
- Lime juice: Adds brightness Freshly squeezed enhances flavor
- Salt and black pepper: Bring everything together Season throughout for balanced taste
- Fresh cilantro leaves and toasted pumpkin seeds (optional): They offer herby freshness and a crunchy finish

- Simmer the Soup:

- Stir in Coconut Milk:
- Once everything is tender pour in the coconut milk Simmer uncovered for five more minutes This makes the soup creamy
- Blend to Your Liking:
- If you prefer a chunkier soup use an immersion blender to blend just a few times for a creamy yet chunky finish For a smooth soup blend until velvet smooth Take care with hot liquid

- Add the juice of one freshly squeezed lime Stir well Taste and adjust salt and pepper to your liking
- Serve and Garnish:

My favorite part is the way the coconut milk mellows the bold spices without overwhelming the earthy lentils and sweet potatoes. Every time I make this soup it brings back memories of cooking together with my daughter while the kitchen fills with cozy smells.
Storage Tips
Let leftovers cool completely before transferring to airtight containers Store in the refrigerator for up to four days or freeze for up to three months. When reheating add a splash of water or broth to bring it back to its creamy texture.
Ingredient Substitutions
No red lentils Use yellow lentils or split peas. Out of coconut milk Try cashew cream or unsweetened soy milk for richness. Switch up the greens with spinach or kale in the last few minutes for extra color.
Serving Suggestions
Serve with a drizzle of coconut yogurt and extra toasted seeds for texture. This soup pairs perfectly with rustic sourdough or a scoop of brown rice in the bowl. I sometimes top mine with thinly sliced red onion and extra lime juice for brightness.
