This Instant Pot Lentil Soup recipe is perfect for an easy lunch or comforting dinner, and it’s full of vegetables and flavor.

Cooking Lentils in the Pressure Cooker

Instant Pot-cooking can make meal preparation in general so easy and fast. I also learned that if you pressure cook lentils or beans, you get the added benefit of having the lectins greatly reduced as compared with regular stove-top cooking. This can be really beneficial for people with lectin sensitivities or autoimmune disease. Isn’t that so interesting?

Not having to pre-soak the lentils means that you can make this Instant Pot Lentil Soup in 30 minutes or less. You’ll need a few veggies to cook with the lentils, including a carrot, celery, zucchini, and about 1/2 of an onion (not pictured).

How to Make Instant Pot Lentil Soup

I promise this is one of the easiest recipes you’ll ever make. You do need to rinse your lentils before you add them to the pot, and then you just have to chop your veggies and toss them in. As with any Instant Pot recipe, you need at least 1 cup of liquid. I used 2 1/2 cups of bone broth since I was making a soup. You can use vegetable broth to make this recipe vegan.

Then, just lock on the lid to your pot, and cook for 15 minutes. You can either do the quick-release or natural release at the end of the cooking time. Lunch or dinner is served!

Some commonly asked questions about cooking lentils the pressure cooker:

What is the benefit of using a pressure cooker versus the slow-cooker? The lectins in the lentils will be reduced, and the whole dish will cook much, much faster!

Is this recipe vegan? Just be sure to use vegetable broth and this recipe will be vegan.

Aren’t pressure cookers dangerous? Can’t they explode? The new electric versions are very safe. Just be sure to follow the directions about the seal and using at least one cup of liquid.
