Ingredients
  

  • 4 boneless, skinless chicken breasts about 1 lb
  • 1 large yellow onion thinly sliced
  • 1 cup low sodium beef broth
  • 2 teaspoon Worcestershire sauce
  • 1 tablespoon Dijon mustard
  • 1 packet dry onion soup mix
  • 4 slices Swiss cheese

Instructions
 

  • Add the chicken breasts to the bottom of the slow cooker, then layer the sliced onions on top.
  • In a large measuring cup, whisk together the beef broth, Worcestershire sauce, Dijon mustard, and dry onion soup mix. Pour the mixture evenly over the chicken and onions.
  • Cover and cook on HIGH for 2 to 3 hours or on LOW for 4 to 6 hours, until the chicken is tender.
  • During the last 10 minutes of cooking, place one slice of cheese on each chicken breast. Cover again and let it melt until soft and gooey, about 5 to 10 minutes.

Notes

  • If you prefer a thicker, gravy-like sauce, remove some of the liquid after cooking and warm it on the stove, whisking in a cornstarch slurry until it reaches your desired texture.
  • For storage, refrigerate leftovers in an airtight container for 3 to 4 days and reheat with a splash of broth to keep the chicken moist. Leftovers can also be shredded and served over rice, potatoes, or veggies for easy lunches throughout the week.
