Ingredients You'll Need
(Serves 4-6)

Step-by-Step Instructions

- Add the Soups: In a bowl, mix together the French onion soup and cream of mushroom soup (and Worcestershire sauce if using). Pour evenly over the chicken.
- Cook: Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the chicken is tender and cooked through (165°F internal temperature).
- Add the Cheese: In the last 15-20 minutes of cooking, lay the Swiss cheese slices over the top of the chicken. Cover and cook until the cheese is melted and bubbly.
- Serve: Spoon the rich, creamy onion gravy over the chicken and serve immediately.
