Easy Sweet Potato and Lentil Soup

Table of Contents

Note from Ana

Growing up on the Adriatic Sea meant eating a lot — and I really mean a lot — of lentils. They showed up in our kitchen all the time, usually in big comforting pots of soup that simmered on the stove. It was simple food, but the kind that warms you up and keeps you full for hours.

Now that I have my own family, I try to keep that little tradition going. Lentils still appear often in my kitchen, and luckily my kids love them too. Our classic Lentil Potato Soup is probably the version I cook the most.

This soup with sweet potato is a slightly different twist, but just as comforting. The sweet potato softens as it cooks and gives the soup a gentle sweetness and creamy texture, while the lentils make it hearty and satisfying. It’s one of those easy soups that tastes like it has been cooking all day, even though it comes together quite quickly.

All the best,
— Ana

Servings

Ingredients

1 tbsp olive oil
1 small onion finely chopped
2 garlic cloves minced
1 tsp fresh ginger grated, or to taste
1/2 tsp ground cumin, or to taste
1/2 tsp ground coriander or to taste
1/4 tsp ground turmeric or to taste
1/4 tsp smoked paprika or to taste (optional)
1 medium sweet potato peeled and diced
1/2 cup green lentils rinsed
2 cups vegetable or chicken broth
2 cups water
salt to taste
black pepper to taste

For garnish, optional:

Fresh cilantro chopped

Instructions

Prepare the Ingredients: Chop the onion, garlic, and sweet potato. Rinse the lentils under cold water.
Sauté the Aromatics: Heat the olive oil in a medium pot over medium heat. Add the onion and sauté for 5 minutes until softened. Stir in the garlic, ginger, cumin, coriander, turmeric, and smoked paprika (if using). Cook for 1 minute until fragrant.
Add Sweet Potatoes and Lentils: Add the diced sweet potato and rinsed lentils to the pot. Stir to coat with the spices.
Add Liquid and Simmer: Pour in the vegetable or chicken broth and water. Bring the mixture to a boil. Reduce the heat to low and let the soup simmer for 20-25 minutes, stirring occasionally, until the sweet potatoes are tender, and the lentils are cooked.
Blend (Optional): For a smoother texture, use an immersion blender to partially or fully puree the soup. If you prefer a chunkier soup, skip this step.
Season and Finish: Season with salt and black pepper to taste.
Serve: Ladle the soup into bowls and garnish with fresh cilantro. Serve hot with crusty bread or naan on the side. Dobar tek!

How to Serve

Serve this soup hot in a deep bowl so all the comforting flavours stay nice and warm. A sprinkle of fresh cilantro on top adds a bright, fresh touch that balances the sweetness of the sweet potatoes and the earthiness of the lentils.

This soup is wonderful with crusty bread, warm naan, or simple toasted sourdough for dipping. If you’d like to make the meal a little more filling, you can also serve it with a simple green salad on the side.

For a cozy dinner at home, I like to bring the whole pot to the table and let everyone help themselves to a second bowl if they want — this is exactly the kind of soup that disappears quickly.

Tips for Success

• Cut the sweet potatoes into small, even cubes. This helps them cook evenly and become tender at the same time as the lentils.

• Rinse the lentils before cooking. This removes any dust and helps keep the broth clear and clean-tasting.

• Let the spices cook briefly with the onion and garlic. Even just one minute helps release their aroma and gives the soup much deeper flavour.

• Add liquid gradually if needed. Lentils absorb quite a bit of liquid while cooking, so if the soup becomes too thick, simply add a splash of water or broth.

• Adjust the texture to your liking. You can leave the soup chunky or blend part of it for a creamier consistency while still keeping some texture.

Substitutions & Variations

You can easily adjust this soup depending on what you have at home.

Red lentils instead of green lentils – they cook faster and will give the soup a softer, creamier texture.
Butternut squash instead of sweet potato – a lovely alternative with a similar natural sweetness.
Spinach or kale – stir in a handful at the end of cooking for extra greens.
Add coconut milk – for a creamier, slightly richer version with a gentle tropical flavour.
Make it heartier – add cooked chickpeas or white beans for extra protein and texture.

Storage & Reheating

This soup stores very well, which makes it perfect for meal prep or easy lunches the next day.

Fridge: Store the cooled soup in an airtight container in the refrigerator for 3–4 days.

Freezer: Freeze in portion-sized containers for up to 3 months. Let the soup cool completely before freezing.

Reheating: Warm gently on the stovetop over medium heat, stirring occasionally. If the soup has thickened in the fridge or freezer, simply add a splash of water or broth to loosen it.
