We didn't think French onion soup could get any more comforting, but we took the Southern route and made it into an even cozier casserole. This dish amplifies the richness of the classic soup you crave, and it's ideal to serve as a hearty family dinner or pack up and bring to the church potluck.
Traditional French onion soup is made with a lot more butter and usually topped with lots of cheese. While it’s delicious, it’s not the healthiest. My recipe calls for just one slice of cheese on each serving. Gruyere cheese is typically used in French onion soup, but Alpine Lace Swiss cheese is a great lighter alternative.
Red onions tend to be too bitter in this dish. You’ll want plenty of butter to cook your onions in. It provides fat which gives this soup sustenance as well as more depth and richness. A brown sugar substitute is going to help this soup to really have a traditional French onion soup flavor. It adds that caramelized element and a touch of sweetness.
