This crazy good recipe combines saucy caramelized onions, juicy chicken breasts, and melty mozzarella and Parmesan cheeses for a family favorite dinner.
In a large sauté pan over medium heat, add the 3 tablespoons salted butter. Sauté for 8 to 10 minutes. Add the garlic, kosher salt and teaspoon pepper.
Stir in the white wine and chicken stock into the caramelized onions and continue cooking for 3 to 5 minutes or until the liquid reduces by about one-half.
