This french onion soup is made easy in the instant pot. It contains onions, beef broth and herbs for a deep caramelized onion flavor.
I’m not sure why, but I always thought french onion soup was such a fancy menu item to order. It was on a lot of diner menus growing up and I often ordered a crock. Especially when I felt under the weather or if it was super cold out side.

I still believe that butter and onions being sauteed together is one of the best smells of all time.
