How Long Do Lentils Take in the Instant Pot?

You’re going to be cooking your lentils for only 12 minutes in this recipe. 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 cooking time to 10 minutes.

If you have leftover dried lentils, use them later to make these incredible Lentil Nachos.

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 snuck 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.

• Brown or green lentils
• Veggies – carrots, celery, onion, potato
• Garlic, thyme, parsley, and Smoked paprika
• Broth – your choice veggie or chicken (related: Instant Pot Chicken Bone Broth)
• Pesto (related: Whole30 Pesto)

Make your prep even easier by learning how to freeze celery, how to freeze garlic and how to freeze onions.

Serve with a side of Air Fryer Biscuits or Air Fryer Texas Toast and your life will be complete.

Pro Tips/Recipe Notes

• This soup was made in an 8 quart Instant Pot. If you have another sized Instant Pot, the cooking 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. 
• Throw in some spinach at the end of the cooking 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.
• You can pump up the flavor by adding a few tablespoons of homemade tomato powder.
• If you want to add meat, I’d recommend some leftover Instant Pot Ham.
