Do you know how ugly lentil soup is? I mean, just downright butt ugly. People say you eat with your eyes first. If that is the case, I would eat lentil soup with my eyes c-l-o-s-e-d.

But if eating visually is the first step, actually tasting food is the next. And when you taste this lentil soup, you’ll forget all about its homely appearance. If you want a pretty (and delicious) soup, check out my Paleo Chicken Pot Pie Soup!

Packed full of veggies and other flavors, this soup is pleased to knock your taste buds proverbial socks off after your initial reaction.

How Long Do Lentils Take in the Instant Pot?

You’re going to be cooking your lentils for only 12 minutes in this recipe. You hear that? Probably not because you’re reading this, so…

This recipe uses brown lentils, but you can also use green lentils and cook for the same amount of time. If you are going to be rocking some red lentils in this recipe, reduce the cook time to 10 minutes.

Do I Have to Soak the Lentils Before Cooking?

Heck no you don’t, not when using the Instant Pot! You will want to rinse them and remove any pebbles or debris that snug their way into your bag of lentils.

But no soaking? Your life is about to rule!

Lentil Soup Ingredients

What’s in this soup? Pure heaven and unicorn dust. And um, lentils.

Have you ever seen a soup recipe that includes something like three carrots, one stalk of celery, and a garlic clove? Amateur hour my friends, amateur hour.

I fully believe that the purpose of soup is to warm your body and soul, create the ultimate feeling of coziness, and shove so many vegetables into one pot that you think it shouldn’t be possible.

And garlic? Oh, friends, I laugh at one clove of garlic. I grow garlic each and every year on my microfarm and I consider it one of the most essential ingredients in my kitchen.

If you want to take your chances with the vampires with your one clove of garlic, then by all means.

Do You Need to Saute the Veggies For Instant Pot Lentil Soup?

Ok, so an older version of this recipe had you sauteing some of the ingredients for a few minutes in olive oil. But then I was like “eff that noise, let’s dump everything in and see what happens”.

Guess what happened? It tasted the exact freaking same. So obviously let’s skip that extra step and make some soup!

How to Make Instant Pot Lentil Soup

Place the lid on and switch it to the lock position. Switch the vent to “sealing”.  Press Manual then High Pressure and adjust the time to 12 minutes. It will take around 10 minutes to get up to pressure.

Once the time is up, allow it to sit for 5 minutes. Then use a kitchen towel and flip the switch to “venting”, and allow it to depressurize fully. It took 8 minutes total for me.

Pro Tips/Recipe Notes

  • No Instant Pot? Crockpot and stovetop instructions are included in the printable recipe card.
  • This soup was made in an 8 quart Instant Pot. If you have another sized Instant Pot, the cook time will be the same. Just make sure you don’t fill the inner pot more than two-thirds full.
  • As written, this recipe is vegetarian. Use a dairy-free pesto to make it vegan. Add some diced ham, bacon (cooked), or sausage (cooked) if you prefer to include meat.
  • Throw in some spinach at the end of the cook time for some added greens.
  • This soup freezes like a boss! Pro tip: freeze in wide mouth pint mason jars for easy grab and go meals.
