I get French Onion soup whenever it’s on the menu, because it’s so good and I love trying different restaurant’s take on this classic French soup. This is my take on French Onion soup and I know you’re going to love it!
The deep, sweet flavor of the caramelized onions pairs so well with the salty broth and gooey cheese that’s melted on top and throughout the soup. I use sherry in the broth to boost that deep, underlying flavor. I add soy sauce to pump up the umami flavor and top that off with the parmesan for the ultimate flavor boost.
What makes a great French onion soup?
In my opinion a great French Onion soup has to have a rich broth, nicely cartelized onions and a rich back flavor which in this recipe I use Sherry to give it that nice depth of flavor. And of course it’s got to be topped with decadent parmesan and grayer.
You don’t need a ton of cheese for this recipe so I recommend that you make sure to get the good stuff, Parmesan Reggiano and Gruyere, it really makes a difference!
