This Instant Pot lentil soup is thick, hearty, and packed with flavor, in great part due the addition of Italian sausage. With a handful of a few simple ingredients, this Instant Pot soup cooks in 12 minutes.

And is making regular appearances at our house.

It’s simply that good! And you can beat this quick and easy soup for getting dinner on the table. Add a salad, maybe, and slices of crusty bread. 

Healthy Instant Pot Lentil Soup

Packed with vegetables and nutritional superfoods, this soup recipe scores big wins for me.

Lentils are part of a superfood category called pulses. They are essentially a dry, edible seed and part of the legume family. Naturally high in protein and fiber, they are also low in fat.

I love lentils and most especially in soup form. When the weather turns chilly, lentil dishes are not far from my mind. Here are a few other lentil recipes I love:

The Lentils in this Instant Pot Lentil Soup

This lentil spinach soup recipe calls for 1 and 1/2 cups of dried lentils. Any variety you have on hand will be delicious.

But if you have a choice, here’s what you should know about lentils.

Brown and Green Lentils:
Easy to find at almost all markets, brown and green lentils are the most common. They cook quickly and tend to fall apart, nicely thickening soups and stews.

Red Lentils:
They bring a beautiful red or orange hue to a dish and are most often found in Indian dishes. The skin of the lentil breaks down quickly and adds a mushiness to the dish. Often they are interchangeable with brown and green lentils but are a bit mushier.

French Lentils:
These lentils have a thicker skin, unlike brown, green, and red lentils. They keep their shape when cooking and are best in non-soup recipes. Salads are perfect.  

How to Make Instant Pot Lentil Soup

Most lentils cook in about 30 minutes. This Instant Pot lentil soup will cook in 12 minutes. Pretty good, right?!

Begin by sauteing the sausage in the Instant Pot. Keeping this recipe easy also includes keeping pots and pans to a minimum. This is a one-pot easy soup recipe you’re going to love.

As far as the sausage is concerned, I like to use a mild Italian sausage, but use the one your family prefers.

Once the sausage has browned and become crumbly, add chopped onions, garlic, and celery; cook for another minute or two.

At this point, the rest of the ingredients; canned tomatoes, dried lentils, and chicken stock are added to the pot. Season with salt and pepper and a pinch of red pepper flakes too. 

Cook on high pressure for 12 minutes. Once finished, quickly release the pressure and remove the lid.

Stir in the spinach and drizzle in the vinegar. Continue to stir until the spinach has cooked and is wilted. Taste and season as necessary with salt and pepper.

I like to sprinkle fresh chopped parsley over the soup once I’ve ladeled into bowls.

And that’s it! My husband likes to add a dollup of sour cream on his and our son likes to sprinkle more (a lot more) red pepper flakes.
