Red Lentil Curry Soup
Red lentil curry soup! A creamy and flavorful combination of sweet potatoes, garlic, onion, red lentils, and coconut milk. A vegan must-make!
Oh, this red lentil curry soup. As in the one I’ve been eating almost non-stop for an entire two weeks. It’s the problem (but not-really-a-problem) of recipe development. Make it, tweak it, and eat it non-stop until you are finally convinced that you’ve found the winning combination. Then, make it again a few days later because you miss it and have to have it.
If you love curry and hearty vegetables, then you’ll love this lentil curry soup. It’s vegan, naturally gluten-free and delicious. With 14 g of protein and 9 g of fiber per serving, this soup is filling and healthy.

Everything You Need to Make this Red Lentil Curry Soup:
Red Lentil Curry Soup Ingredient Notes
- White onion: I prefer cooked white onion in soup, but you can use yellow onion or sweet onion. I don’t typically like cooked red onion in soup and stews.
- Curry powder: My favorite curry powder is from Penzey’s (the now curry) but any curry powder will work.
- Sweet potato: I don’t recommend omitting the sweet potato as it makes up the bulk of this curry soup, but you can also substitute butternut squash.
- Dry red lentils: The red lentils are a must in this recipe as they cook down while cooking and almost melt into the soup. Brown lentils or green lentils won’t work the same way.
- Diced tomatoes with juice: Fire-roasted tomatoes will also work.
- Light coconut milk: This really adds to the soup and gives extra flavor and richness. You can use regular coconut milk if you want a more full-bodied red lentil curry soup.
How to Make Red Lentil Curry Soup
Cook the Vegetables
In a large pot, cook the onion, garlic, ginger, and curry powder and cook, stirring often until the onion is soft, about 3 minutes.
Add the Sweet Potatoes
Add sweet potatoes, lentils, tomatoes, salt and broth. Cover and cook, covered, stirring occasionally, until the sweet potatoes are tender and the lentils are mostly broken down.
Stir in the Coconut Milk
Stir in the coconut milk and simmer until heated through. Puree some of the soup, if you’d like, for a creamier texture. Stir in the lime juice and cilantro, and serve.
I think we’ve all had some version of the ubiquitous lentil soup. Well, this is not your momma’s lentil soup! It’s creamy and spicy with a hint of richness. It may be the best lentil soup I’ve ever made.
Tips for Success
The cool thing about red lentils is that they almost dissolve into the soup completely, so you’re left with a chunky stew thickened by beans! Red lentils are the best for this, and I don’t recommend substituting in brown lentils or green lentils.
If you want a creamier texture, puree some of the soup with the coconut milk and then add it back in. You can do this either with a regular blender or an immersion blender.
As with most soups, the addition of lime juice really accentuates the flavor and cuts through the rich flavor. A little acid in soup is one of my secret cooking tips!
Finish this one with a generous stir-in of coconut milk and fresh cilantro. This is one lentil soup that can’t be missed.
