This Baked Swiss Chicken is an easy, comforting dinner made with tender chicken breasts baked in a creamy celery sauce and topped with melted Swiss cheese.
Preheat the oven to 350°F. Trim any excess fat from the chicken breasts, then carefully slice each breast in half horizontally to create thin filets.
Arrange the chicken filets in a 9×12 baking dish. It’s fine if they overlap slightly. Season both sides with salt and pepper.
Pour the cream of celery soup over the chicken and use a spatula to spread it evenly across the dish, making sure each piece is coated.
Bake for 20 minutes, or until the chicken is just cooked through.
Lay the Swiss cheese slices evenly on top of the hot chicken and sauce. Return the dish to the oven for 5 additional minutes, or until the cheese has fully melted and becomes bubbly around the edges.
Let the dish rest for a few minutes, then serve warm with your favorite sides.
