Looking for a simple weeknight meal that won’t keep you in the kitchen for hours? Turn to your Instant Pot to make an easy, healthy soup in 30 minutes. This barley soup recipe calls upon the flavors of mirepoix—the classic French trifecta of onions, carrots, and celery.



Pair it with a sandwich or salad for a filling, well-balanced meal. You can also make this soup over the stove or in a crockpot.
