This Instant Pot Spiced Red Lentil Sweet Potato Soup is one of my favorite easy recipes, and it’s one that you all like so much too!
It’s a creamy and thick spiced soup that gets its natural creaminess from red lentils and sweet potatoes. No coconut milk needed to thicken it up because red lentils get mushy when cooked, plus the Instant Pot melts the sweet potatoes into the soup.

Why you’re going to like this recipe
10 main ingredients. Okay, I’m not counting oil, salt and pepper. But yeah, 10 main ingredients, yay!
Weeknight-friendly. It requires just 5 minutes of hands-on cooking, so it’s definitely an easy option for those busy weeknights.
Hearty yet wholesome. This recipe is hearty and comforting, the kind of soup that’s more stew than soup and that’s super satisfying, thanks to its creamy texture, the protein-packed lentils, and the complex carbs from the sweet potatoes. This makes it a great meal for the whole family!
Perfectly spiced. If you’re tired of the same old meals, this is a recipe to try! It features Indian spices but it’s still very accessible and doable, even for novice cooks. The Indian spices pair perfectly with the red lentils (a classic combo), and are balanced nicely by the sweetness of the sweet potatoes.

This recipe is super easy to make so there’s not much to say, but keep in mind that this soup is quite thick and creamy, almost like a stew or dal. If you prefer a soupy texture, just add more vegetable broth or water.
You can add the extra broth/water before pressure cooking (in step 3), or after pressure cooking once you see the finished texture so you can add as much liquid as needed.

Instant Pot Spiced Red Lentil Sweet Potato Soup

Ingredients
- 1 tablespoon coconut oil (or oil of choice)
- 1 medium onion, diced
- 2 garlic cloves, minced
- 1 1/2 tablespoons freshly grated or minced ginger
- 1 serrano pepper, diced (optional, adds some heat)
- 2 teaspoons garam masala
- 1 teaspoon curry powder (optional)
- 1 teaspoon ground cumin
- 1/2 teaspoon ground turmeric
- 2 medium sweet potatoes, peeled and cut into a large dice
- 1 cup red lentils, rinsed until the water runs clear
- 4 cups low-sodium vegetable broth*
- 1 1/4 teaspoons sea salt + more to taste
- Freshly cracked black pepper
- 1-2 teaspoons maple syrup (optional)
- For serving (optional): coconut yogurt, fresh cilantro, and flatbread or rice
Instructions
- Select the Sauté setting on your Instant Pot and heat up the coconut oil. Once it’s shimmering, add the onion and cook for 3-4 minutes until slightly softened.
- Add the garlic, ginger, serrano pepper (if using), garam masala, curry powder (if using), cumin, and turmeric and stir until aromatic, about 30 seconds.
- Pour in the vegetable broth to deglaze the pot, using a wooden spoon or scraper to scrape up any browned bits on the bottom of the pot. Add the lentils, sweet potatoes, sea salt, and pepper. Stir to combine all of the ingredients. Select the Cancel setting.
- Secure the lid of the Instant Pot and seal. Select the Pressure Cook (or Manual, depending on your model) setting and cook at high pressure for 10 minutes.
- Once the 10 minutes is up, allow a natural pressure release for 10 minutes before switching the pressure release valve from Sealing to Venting. Open the Instant Pot and give the soup a stir. Taste for seasonings. You may want to add more salt, or to balance the acidity, you may want to add a teaspoon or two of maple syrup or sugar.
- Once the soup has slightly cooled, top with coconut yogurt and fresh cilantro. If desired, serve with flatbread or rice.

So good! Even my lentil hating husband loved it!
Wow Sweet and Delicious!!!! I made this recipe without curry, but love the garam masala *** I Added lightly steamed cauliflower in just before serving….. I would try adding steamed potatoes, mushrooms and spinach next time…. Thanks for taking all the guess work out of this great recipe Nisha!!
Delicious, quick and easy! And pantry friendly. I added some kale and stirred it in at the end to add some greens! Thanks for a wonderful recipe.
I only have a 3-quart instant pot. Should I reduce the amount I make or will this recipe fit in that size pot?
Sabina I made this today in a 3 quart instapot did fine used 1 cup of lentils one very very large sweet potato and 4 1/2 cups of ginger broth it did fine…..
Nisha, I love your recipes. I am nearly fifty years old and I am just now starting to feel like I can call myself a good cook. Much of that is thanks to your recipes! This is one of my favorites. The flavors are fantastic and the sweet potato and lentils are a wonderful combination. As I ate this I was thinking, I can’t believe I made this!! Thank you for a home run of a recipe
Hi, I don’t have an instant pot. Would I decrease the amount of water or increase the cooking time on stovetop?
I haven’t tried it myself, but I think you can decrease to 3 cups liquid. And after sauteing the onions, add the sweet potatoes and toss to coat for 6-7 minutes (add more oil or water as needed to prevent sticking). Then add the lentils and liquid, and probably 20-25 minutes cook time.
Sooo good!
Ok this recipe sold me on instapot soups! It so warming and filling. I added eggplant, chickpeas, and spinach at the end too. I chose this because I already love the red lentil curry and make it often. And I need to get my iron in lol
