This recipe for Instant Pot French Onion Soup with buttery caramelized onions in a rich beef broth is the easiest way to make this classic dish.
French Onion Soup is the perfect balance of comforting and creamy without being too heavy.
This Instant Pot version is adapted from the Creamy Swiss Onion Soup in my Electric Pressure Cooker Cookbook, updated with air fryer lid directions!
It’s just as full of deep caramelized flavor as the stovetop version, in a fraction of the time. Garlic, thyme, and beef broth build rich and savory flavors in the soup. And of course, we top off each bowl with a slice of crusty bread and melty gruyere cheese.
