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.
Notes

I made this in a dutch oven to use some already roasted sweet potatoes. Cooked everything but them following the recipe then put them in the dish to heat through. They gave a distinctively caramelized tone to the dish that balanced the heat.
We’re so happy you enjoyed the recipe, Evan! :)
