Vegan Instant Pot Lentil Soup Recipe

This Instant Pot lentil soup recipe is perfect for anything from the still-chilly evenings of spring to the bone-cold nights of winter!

You can’t go wrong with lentil soup. I grew up enjoying a German version of this soup on a regular basis. So to say that it’s comfort food for me, is an understatement. It’s warm, comforting and definitely fills you up.

Cooking lentils in an Instant Pot couldn’t be easier! Simply combine the lentils and the water (or use equal amounts of veggie broth for added flavor!) in the pot, place the lid and close the vent, then press the manual button and adjust pressure to high. Adjust time for whichever type of lentil you are cooking. Here’s a cheat sheet.

Note that these times are for the lentils only. Times can differ if you are making soups or other dishes.

  • Brown Lentils – 14 minutes – 10 minute natural release
  • Green Lentils – 13 minutes- 10 minute natural release
  • French Green Lentils – 7 minutes – 10 minute natural release
  • Red Lentils – 2 minutes – Quick release. However, be aware that red lentils tend to fall apart in a pressure cooker. So it’s really only appropriate for soups.


You don’t have to. In fact, it’s best not to soak lentils before cooking them in an Instant Pot or other pressure cooker. Lentils don’t require soaking like beans do. That being said, if you do soak them, you can cut down on the cooking time by half. But that really only matters when being cooked on the stove top. It doesn’t really apply here.

Lentil soup is pretty much a meal onto itself. But it does have a few things that pair nicely with it to round out the meal. Namely…

  • A slice of crusty bread
  • A dinner roll
  • Crackers
  • A side salad
  • A warm cup of tea


Typically, for stove stop cooking, you would use 3 cups of water for each 1 cup of dry lentils. But things change slightly in a pressure cooker. For this, you only need 2 cups of liquid for every 1 cup of dry lentils.
