This Instant Pot Red Lentil Soup is vegan and gluten-free. The soup is made with red lentils which are a variety of lentils with a salmon color.

I love making soups for dinner when the weather is cold, I get to use up lots of vegetables and they are so warming and filling! Making soups in the electric pressure cooker makes like so much easier.

They are so easy to prepare and cook in minutes, other varieties are brown, green, yellow, and black lentils. 

The pasta was added for a heartier soup, you can leave it out if you prefer.

What Kind Of Pasta Do You Use In Red Lentil Soup?

We used dried gluten-free elbow pasta that is cooked directly in the soup. Make sure to get a sturdy pasta that cooks for at least 5 minutes on the stovetop.

If you are in doubt that the texture of your pasta will hold up?

You can cook the pasta separately according to the package directions and add it to the finished soup. This will prevent you from having overly soft or mushy cooked pasta.

Are Lentils Good For You?

Lentils are packed with nutrients, they are healthy and filled with dietary fibers which are both soluble and insoluble. Insoluble fibers are great for a bowel movement, they prevent constipation.

Lentils contain a great source of magnesium, iron, zinc, and folate. They are a good source of protein and complex carbohydrates.
