Recipe Instructions
Step 1
In a medium saucepan over medium heat, cook butter until foamy. Stir in onions and cook a couple of minutes, then reduce heat, stir in salt, cover and cook very slowly until very tender, 60 minutes.
Step 2
Transfer onions and their caramel to a larger pot and place it over medium heat. Pour in the wine and bring to a boil. Stir in chicken broth, pepper and nutmeg and simmer gently, uncovered, 15 minutes.
Step 3
Stir in shredded cheese until melted (cheese will remain a little stringy). Serve.
