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.

For a visual on how to make this recipe, check out the video on Youtube! It’s the first recipe in the video and starts around the 00:55 mark.

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.

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.

    I had made this several times before and loved it. So recently I decided to try it for our backpacking trip. I made it without the oil because you can not dehydrate food with alot of oil in it. So I sweated the onions in some water, then followed the directions as written. When it was finished I let it cool completely, lined my dehydrator with parchment paper and spread it out on 4 trays to make 4 servings. After dehydrating, it was easy to put in 4 ziploc bags to pack on our backpacking trip. I added 1 1/4 cup boiling water to each serving and 1 T. olive oil that I had brought along. It was light weight to pack, and delicious after a day of hiking!

  4. Priyanka says:

    Loved this recipe, I omitted the vegetable broth and used water instead and it still had so much flavour from the spices.

    I also blended the soup at the end which gave it a lovely smooth texture.

    1. Kaitlin @ Rainbow Plant Life says:

      It’s so great to hear you enjoyed the soup, Priyanka! Next time, would you mind leaving a rating alongside your review? Star ratings are big help to readers who are thinking of making the recipe. Thanks!

    This came out amazing! I made it on Sunday so I have soup for the week at work. Monday when I warmed it up I had a several people say it smelled amazing and now they were hungry! LOL

    1. Kaitlin @ Rainbow Plant Life says:

      We’re so happy that the soup turned out well for you, Shannon. Thank you for taking the time to leave a comment and for trying out the recipe!

  9. Kat says:

    I don’t have an instant pot. Could I make this over the stove or in a crockpot? Any ideas on how that would work?

    1. Kaitlin @ Rainbow Plant Life says:

      Hi Kat, We haven’t tried making this on a stovetop ourselves, but this would be our best guess:

      1. Heat a large soup pot over medium heat and add the coconut oil.
      2. Add the onion and cook for about 4 to 6 minutes until softened.
      3. Add the minced garlic and grated ginger, and sauté for another minute or so until fragrant.
      4. Stir in the garam masala, curry powder, ground cumin, and ground turmeric. Cook the spices with the onions for another minute to toast them slightly, stirring frequently.
      5. Pour in the rinsed red lentils, sweet potatoes, and vegetable broth. Stir well to combine all the ingredients.
      6. Bring the soup to a boil, then reduce the heat to a simmer. Cover the pot and let it simmer for about 20-30 minutes or until the lentils and sweet potatoes are tender.
      7. Use an immersion blender to puree the soup until smooth. Alternatively, you can carefully transfer the soup to a blender in batches to blend until smooth and then return it to the pot.

      Hope this helps!

      2. Paula says:

        Coconut milk in step 7? No coconut milk in instant pot version.

        1. Kaitlin @ Rainbow Plant Life says:

          Thanks for catching that, Paula! I modified this answer from another recipe and must have accidentally kept that in.

      3. Kat says:

        THANK YOU!

    I was feeling under the weather this evening so I was looking for something comforting and relatively easy to make. This recipe fit the bill perfectly and I had everything on hand. I was surprised to see my CSA sweet potatoes were of the purple variety so my soup looked… interesting but tasted amazing. Great flavors as usual.

    1. Kaitlin @ Rainbow Plant Life says:

      Thanks for the lovely feedback, Jenni! We hope you’re feeling better now 🙂

    Amazing, so easy to make the flavor is off the charts. I did omit the serrano pepper. This will be my lunch for the week. I love an easy flavorful recipe to set my week up for success.

    1. Kaitlin @ Rainbow Plant Life says:

      Hi Lisa, thank you so much for your kind review!

    This recipe is so good! Definitely a keeper.

    My only critical feedback is that it takes much longer to prepare than it says, even for an experienced cook. It shows 15 minutes of cook time, but the instant pot has to build pressure, cook for 10, natural release for 10, etc.

    1. Kaitlin @ Rainbow Plant Life says:

      Lovely to hear you enjoyed the soup, Sheri! Sorry it took longer to cook than expected. We appreciate the feedback!

    This recipe is so delicious Nisha 😩 thank you so much for your work! You’ve made my plant based journey so simple 💗

    I would’ve never thought of combining red lentils with sweet potatoes, what a delicious combination!

    1. Kaitlin @ Rainbow Plant Life says:

      Neo, So glad to hear you loved this recipe, and that the recipes in general are helping you on your plant-based journey! 🙂

    I LOVE this recipe. I’ve made it at least a dozen times and going to make it again right now ❤️

    1. Kaitlin @ Rainbow Plant Life says:

      Thanks for the lovely feedback, Jenni! 🙂

    2. Jenni says:

      Well- I feel silly haha my brain thought this was the sweet potato dal! Which I just made and LOVE. So since it’s very similar I’ll have to make this next!

    Love this! I made it on the stove and roasted my sweet potato in the oven & then stirred it in to get it uniformly creamy. I also added mustard seeds, hing, fenugreek leaves, and some frozen shredded coconut. Your recipes never disappoint, and I especially love your Indian fusion recipes like this one — dal and sweet potato soup are a match made in heaven!

    1. Kaitlin @ Rainbow Plant Life says:

      Thank you so much for sharing, Rose! We’re thrilled you love the recipes 🙂

  20. Lynnette Bean says:

    Is this chunky? In other words, are chunks of sweet potato left after cooking?

    1. Support @ Rainbow Plant Life says:

      Hi Lynnette, sorry for the late response! It will likely be a bit chunky but if you prefer it smooth, you can use an immersion blender or transfer to a stand blender and blend with the small cap in the center removed and covered with a towel. Enjoy!
