Key Ingredients

You only need few pantry staples plus some fresh veggies and herbs to prepare the best instant pot lentil soup.


Dried red lentils are one of my favorite legumes for soups and stews. They cook quickly, pack a lot of nutrients, and are very versatile. Lentils are great source of protein, plus they have a lot of fiber, which is good for digestion and keep us full longer.

Don’t use canned lentils as they are already cooked and will fall apart completely.


Use your favorite canned crushed or diced tomatoes, or good quality passata. If you have fresh tomatoes that are very ripe you can use them too.


I usually use regular yellow onion or red onion in soups. Shallots will do nicely too.

Garlic is quite important in this recipe, not only for the health benefits. It adds deeper warm flavor and combines perfectly with rest of the spices.


Feel free to add other vegetables that you like. Here are the basic vegetables that I like to use:





I like to shortly sauté veggies using olive oil, because of it’s health values and specific pungent flavor.

You can use other vegetable oil like canola or grapeseed as well.


Adjust the quantity to your liking. You can add other herbs that you like, this recipe is really very adjustable.

  • dried thyme
  • dried oregano
  • dried parsley
  • curry powder

Try preparing ORIENTAL version of this soup. Swap herbs for fresh ginger, ground cumin, turmeric and red pepper flakes.

How To Make Best Instant Pot Red Lentil Soup


Prepare all your veggies and spices to be added to the soup. Peel and chop onion & garlic, carrot, potatoes. Measure the remaining ingredients.

Rinse the lentils until the water is clear. You may soak them, but it’s not necessary with red lentils. They cook quickly, especially in pressure cooker.

If you’re new to pressure cooking, please note that those preparations make your life easier and speed up the process. After the next step – sautéing is done, you will put all ingredients together in the Instant Pot and that’s it. If you prepare everything in advance you won’t forget any ingredient.


Add olive oil to instant pot and set it on ‘sauté’ at the lowest setting. Add onions and fry them for 2-3minutes until translucent. Stir garlic in and cook for another minute.

When the onion and garlic are done pour 1 cup of vegetable broth into the pot to deglaze it. Stir with a silicone of wooden spoon, to make sure that no onion is stuck to the bottom of the pot. This is called deglazing.

You can ‘cancel’ the ‘saute’ option now.


Add all the remaining ingredients to the Instant Pot and stir everything well. The liquid should cover the veggies. Lentils will drink most of it up.

Place the lid on the Instant Pot and close it carefully. Turn the steam release valve from ‘Vent’ to ‘Seal’ position.

Press ‘Pressure Cook’ on lower setting, set the timer to 5 minutes and turn the ‘Keep warm’ function off.

Done! Soon you will have hot, hearty soup ready to enjoy.

You deserved a coffee break!


Once the cooking is done, you can use quick pressure release or natural release and open your Instant Pot. The vegetables will be well cooked and lentils – soft and almost-falling-apart.

Can I Blend Red Lentil Soup?

Yes, it will make a nice creamy soup.

I would take 1 cup of the vegetables out of the pot, blend the rest with immersion blender and put the unblended veggies back. This way you will have a creamy soup with additional texture.

Can I Use Other Type Of Lentils?

You can use green lentils or brown lentils instead, but I would soak them for at least 30 minutes before cooking. They have longer cooking time than red lentils.
