Only 4 ingredients. I prep it when I want dinner ready hours in advance.

This 4-Ingredient Creamy Swiss Chicken Bake is pure comfort food at its easiest. Tender chicken bakes beneath layers of melted Swiss cheese, while a simple blend of sour cream and cream of chicken soup creates a rich, slightly tangy sauce that keeps everything moist and flavorful. It’s the kind of effortless weeknight dinner that tastes far more indulgent than the prep time suggests.

4-Ingredient Creamy Swiss Chicken Bake

Ingredients

Ingredient	Amount
Boneless, skinless chicken breasts	4 (about 2 lbs)
Swiss cheese slices	8
Cream of chicken soup	1 (10½ oz) can
Sour cream	½ cup
Salt and black pepper	To taste

Directions

Step 1: Prepare the Oven & Dish
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.

Step 2: Season the Chicken
Pat the chicken breasts dry to help the seasoning adhere. Trim any excess fat, season both sides with salt and black pepper, and arrange them in a single layer in the baking dish.

Step 3: Add the Cheese
Lay two slices of Swiss cheese over each chicken breast, slightly overlapping to fully cover the surface.

Step 4: Make the Sauce
In a medium bowl, whisk together the cream of chicken soup and sour cream until smooth. Spread the mixture evenly over the cheese-covered chicken.

Step 5: Bake
Cover the dish tightly with foil and bake for 25 minutes. Remove the foil and continue baking for another 20–25 minutes, until the chicken reaches an internal temperature of 165°F and the sauce is bubbly and lightly golden.

Step 6: Rest & Serve
Let the dish rest for 5–10 minutes before serving so the juices redistribute and the sauce thickens slightly—perfect for spooning over rice, potatoes, or vegetables.
