Ingredients

Scale
  • 4 cups cooked chicken breast, shredded or chopped (about 600g or 1.3 lbs)
  • Salt and pepper, to taste
  • 1 can (10.5 oz) cream of chicken soup (or cream of mushroom)
  • 1 cup sour cream (full-fat recommended; Greek yogurt for lighter option)
  • 1/2 cup milk (whole or 2%; or unsweetened almond milk)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 8 slices Swiss cheese (about 7 oz)
  • Optional: 1/2 cup shredded mozzarella or provolone
  • 1 package (6 oz) seasoned stuffing mix
  • 1/2 cup unsalted butter, melted (or olive oil)
  • Optional: 1/3 cup chopped fresh parsley

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish with butter or nonstick spray.
  2. Layer cooked chicken evenly in the bottom of the dish. Season with salt and pepper.
  3. In a mixing bowl, whisk together cream of chicken soup, sour cream, milk, garlic powder, and onion powder until smooth.
  4. Lay Swiss cheese slices evenly over the chicken. Sprinkle optional shredded mozzarella or provolone if desired.
  5. Pour the creamy sauce over the chicken and cheese layers. Spread evenly with a spatula.
  6. In another bowl, toss stuffing mix with melted butter (or olive oil) until evenly coated. Add parsley if desired.
  7. Sprinkle the stuffing mixture evenly over the casserole. Lightly press down.
  8. Bake uncovered for 35–40 minutes, until the top is golden and the casserole bubbles at the edges. If the stuffing browns too quickly, cover loosely with foil for the last 10 minutes.
  9. Let rest for 5 minutes before serving. Serve hot.

Notes

For gluten-free, use gluten-free stuffing mix and cream soup. For dairy-free, substitute coconut yogurt and dairy-free cheese. Rotisserie chicken saves time. Add veggies like spinach or broccoli for extra nutrition. Broil the last 2 minutes for extra crunch. Assemble ahead and refrigerate; add 5–10 minutes to bake time if cold.
