Ingredients

  • 4 boneless skinless chicken breasts
  • 2 teaspoons kosher salt divided
  • 1 teaspoon ground black pepper divided
  • 2 tablespoons olive oil divided
  • 2 garlic cloves minced
  • 2 yellow onions thinly sliced
  • 2 tablespoons unsalted butter
  • 2 teaspoons granulated sugar
  • 2 tablespoons all-purpose flour
  • ½ cup dry white wine
  • 1 tablespoon Worcestershire sauce
  • 2 teaspoons fresh thyme leaves
  • 1 cup beef broth
  • 6 ounces Gruyere or Swiss cheese shredded

Instructions

  • Preheat oven to 350 degrees F. Pat chicken breasts dry and use a meat mallet to gently pound them to an even thickness. Sprinkle chicken with 1 teaspoon salt and 1/2 teaspoon pepper.
  • Heat 1 tablespoon oil in large oven-safe skillet over medium heat. Transfer chicken to skillet and cook 8 minutes or until golden brown, turning once halfway through cooking. Transfer chicken to plate. 
  • Reduce heat to medium-low and add garlic, onions, butter, sugar and remaining 1 tablespoon oil to skillet. Cook 35 to 40 minutes or until onions are deep golden brown, stirring occasionally. 
  • Add flour to skillet and cook 1 minute, stirring constantly. 
  • Stir in wine, Worcestershire sauce, thyme, and remaining 1 teaspoon salt and 1/2 teaspoon pepper and cook 1 minute or until most of the wine is evaporated.
  • While stirring constantly, gradually add broth until all broth is incorporated. Heat to simmering over medium-high heat, then remove from heat. Add chicken back to skillet, nestling the chicken into the onion mixture.
  • Sprinkle cheese over chicken and transfer skillet to oven. Cook 14 to 16 minutes or until cheese is melted and internal temperature of chicken reaches 165 degrees F.

Notes

  • Use an instant read thermometer to check the internal temperature of the chicken. Make sure it reaches 165 degrees F and no higher.
  • If you don’t have an ovenproof skillet, you can transfer the chicken and onion mixture to a baking dish before baking.
