This Sweet Potato Red Lentil Soup is a healthy and low-calorie soup that is perfect for a simple lunch or weeknight dinner. This soup is made extra flavourful with the addition of curry and is as comforting as it is delicious.
How to Make it
This is a great recipe to make when you are pressed for time since this delicious soup comes together quickly. In fact, once you've prepared the main ingredients, this sweet potato and lentil soup can be ready in just about 30 minutes.
And you don't need an instant pot or pressure cooker to do so. By using split red lentils instead of brown or green lentils, you can reduce the amount of cooking time significantly.
To make this hearty soup extra flavourful, I use aromatic ingredients and spices such as garlic, onions, ginger and curry, all of which complement sweet potatoes and lentils.
- Olive oil
- Fresh ginger
- Sweet potato
- Split* red lentils
- Chicken or vegetable broth
- Curry powder, hot or mild
- Ground turmeric
- Sea salt and black pepper to taste. A pinch of cayenne pepper or red pepper flakes can also be added to make the soup spicier.
- Fresh lemon juice or lime juice - Adding a squeeze of lemon juice really perks up the flavors.
- Yogurt or sour cream, optional (for topping)
Once you've gathered and prepped your ingredients, you'll want to start by cooking the aromatics in a large pot on your stove top so you can build the flavour base of your soup.
Then you'll add the broth, lentils and sweet potatoes. Let the soup simmer over medium-low heat until the ingredients are tender, adjust the seasonings to your liking and the soup is ready.
You can leave the soup chunky or or for a more creamy texture, purée all or part of it in the blender or by using an immersion blender.
You can also make this sweet potato soup in a slow cooker. For the best flavour, cook the aromatics on the stovetop before adding them to your slow cooker along with the rest of the ingredients. Cook on low for about 8 hours or on high for 5 hours or until the lentils are cooked.
- Depending on the level of heat you like, you can choose a mild or spicy curry.
- Make this sweet potato soup vegan by substituting the butter with coconut oil or another oil and using vegetable broth.
- Make this sweet potato lentil soup creamier by adding coconut milk. To do so, reduce the amount of broth by about one cup and add one cup of creamy coconut milk.
- Serve the soup chunky or purée part or all of it for a creamier texture.
How to Serve
You can serve this soup with a wedge of lemon or lime and a dollop of yogurt or sour cream. A sprinkling of fresh cilantro would also make a great addition. You can also serve it with some hearty bread for a more filling and comforting meal.
How to Store
Leftover puréed sweet potato and lentil soup can be frozen for later consumption. Simply cool the soup entirely before storing it in a freezer container and freezing. If the soup separates after thawing, simply blend the soup in your blender to get it back to a creamy consistency.

- Bring to a boil and then lower heat to a simmer and simmer the soup for approximately 15 minutes, stirring now and then so the lentils don’t stick to the bottom of saucepan.
- When the sweet potato and lentils are tender, add 2 tablespoons of freshly squeezed lemon juice, salt and freshly ground pepper to taste.
- You can either keep the soup chunky or using a stick blender you can purée part of the soup or all of it if you prefer a creamier texture. You can also transfer the soup in batches to a blender and purée until smooth. Pour the soup back into the saucepan and adjust the seasonings and consistency of the soup with more broth or water.

- You can use regular red lentils for this soup but they take twice as long to cook as split lentils.

- If you're adding coconut milk to this soup, reduce the amount of broth by the same amount of coconut milk you are going to use (one regular sized can contains about 400 ml). You could always add more broth to thin out the soup if you find it too thick.
