Ingredients
  

  • 4 boneless, skinless chicken breasts
  • 1 cup (240 ml) sour cream or plain Greek yogurt
  • 10.5 oz (300 g) can cream of chicken soup
  • 1.5 cups shredded Swiss cheese
  • 6 oz (170 g) box stuffing mix
  • 0.5 cup (115 g) unsalted butter, melted
  • salt and black pepper, to taste
  • 1 cup optional: steamed broccoli florets or sautéed mushrooms

Equipment

  • 9x13-inch baking dish
  • Mixing bowls
  • Whisk
  • oven mitts
  • Measuring cups and spoons

Method
 

  1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
  2. Place the chicken breasts in an even layer in the baking dish. Season both sides with salt and pepper.
  3. In a bowl, whisk together sour cream and cream of chicken soup. Spread this mixture evenly over the chicken.
  4. Sprinkle the shredded Swiss cheese over the creamy layer, covering all the chicken pieces.
  5. In a separate bowl, mix the dry stuffing mix with the melted butter until evenly coated. Spoon this mixture over the top of the casserole, spreading it evenly.
  6. Bake uncovered for 35–40 minutes, or until the chicken is fully cooked (165°F / 74°C) and the topping is golden brown and crisp.
  7. Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired and enjoy!

Notes

Add steamed broccoli or sautéed mushrooms for extra flavor and texture. Use Greek yogurt instead of sour cream for a lighter option. Let the casserole rest for 5 minutes before serving so the layers set perfectly.
