A delicious and creamy Instant Pot red lentil soup that is easy to make and loaded with wonderful flavors. With simple seasonings and just a touch of fresh ginger, this hearty and vibrant soup is perfect for any time of the year. This is one of my favorite Instant Pot soup recipes and i’m excited to share it with everyone.
What Are Red Lentils?
Red Lentils don’t get enough credit in the legume world. They have a wonderful, delicate, slightly sweet flavor and provide a wonderful texture when cooked into a soup. They readily take on the flavors that are added to it, while providing a heartiness all their own. Red lentil soup shares some of the texture and consistency of split pea soup, while being a bit on the lighter side.
A Simple Mirepoix Base, Seasonings and Ginger
This recipe starts with onion, celery and carrots, when diced and sauteed in a little butter. This is called a mirepoix. It’s the base for many popular soups. The aroma will have everyone asking “what smells so delicious?” After the vegetables are sauteed, we add a can of fire roasted diced tomatoes. I’m a huge fan of fire roasted tomatoes and they further accentuate the heartiness of this soup with rich, deep flavors. Then we add a half teaspoon each of cumin and turmeric. Both seasoning will further deepen the flavor profile and the ginger will add just a bit of vibrance.
Chicken Broth or Vegetable Broth?
Both chicken broth and vegetable broth provide the liquid base for the soup in similar ways, but I find that a good chicken broth fills out the flavor profile the best.
Blend to Desired Consistency
Once our soup is done cooking in the Instant Pot, it’s time to blend it. An immersion blender is a great tool for soup recipes. Just place it directly into the pot and blend for about 20 seconds to leave the soup with a little bit of a thick and chunky texture.

I have to admit I have never made Lentil soup. Trying to get healthier for my husband and I. So, I made it to see IF I liked it first. Well it is wonderful! I also have to admit that I did sauté the vegetables in a little garlic because I put garlic in almost everything! Would recommend making this and thanks for sharing this recipe!

Hi Mak,
Yay!!! I love this recipe so much too! A little garlic is a perfect addition.

Absolutely delicious!! First time I made this, but it definitely won’t be the last! I didn’t change a thing and I love it. Hubby coming home from a hard day at work, it is cold outside, and I know he’s going to love this soup, too. Thank you so much for another great recipe!

Made the soup today with just two exceptions: used veg broth (since I am vegan) and didn’t have any fire roasted tomatoes on hand. I only had plain tomato sauce (but also added a bit of cayenne). It wasn’t too spicy and loved the flavor of the added ginger.
It was fabulous and most likely one of my top 3 favorite soups! THANK YOU!

Not really a success. I think there were two issues. One, I didn’t have a “vanilla” can of Fire Roasted Tomatoes. I used a can that had green chilies added. Used this in other dishes and hasn’t added a lot of spice. Two, too much pepper. This seems to be recurring with recipes on this blog. Soup had way to much heat and the pepper, even though I was shy the amount called for was overwhelming. If I try this again I’ll use “vanilla” diced tomatoes and with the pepper mill on the table people can add their own black pepper.
Used whole red lentils and they were completely dissolved following the recommended time and quick release so I can confirm split lentils aren’t needed. Texture after blending was great. Just too much spice/heat. Disappointing since I bought a bottle of Turmeric just for this dish.

I’m thinking of making this soup since my husband just purchased 25 pounds of red lentils. My lentils are regular, NOT split. Can I still use these in this recipe?
RecipeTeacher
Now that’s gonna be a lot of soup! 🙂 you can make it with whole lentils no problem. Everything will be the same.

Delicious! Used my own frozen, roasted Roma tomatoes from last summer.
Served with grilled cheese sandwiches. There are no leftovers for lunch tomorrow. Darn, I may have to make it again.
