Recipe Ingredients

Chicken Breasts: I like to use boneless skinless chicken breasts for this recipe. You can either find thinly sliced chicken or cut the breasts in half for thinner chicken pieces.
Onion: A medium sweet yellow onion sliced and slow cooked with the other ingredients not only adds flavor but also provides a little texture with the chicken.
Onion Soup: Skip making this homemade and grab a can of Campbell’s French onion soup, or use a brand of your choice.
Lipton Onion Dry Soup Mix: This soup mix is found in packet form and has all the added flavors you’ll need for making a delicious meal.
Swiss Cheese: You can use the sliced Swiss cheese purchased in the pack or sliced from the deli. Once melted, you’ll have a gooey cheese that takes this baking dish to a new tasty level.
