Ingredients
 

Main Ingredients

  • 2 lb boneless, skinless chicken breasts halve thick pieces for even cooking
  • 1 tsp kosher salt
  • 0.5 tsp ground black pepper
  • 0.75 tsp garlic powder
  • 0.5 tsp dried thyme
  • 8 oz Swiss cheese sliced or shredded
  • 10.5 oz condensed cream of chicken soup
  • 0.75 cup sour cream
  • 0.5 cup low-sodium chicken broth or use dry white wine
  • 1 tsp Dijon mustard adds gentle tang
  • 3 cup dry stuffing mix
  • 0.33 cup unsalted butter, melted
  • 2 tbsp fresh parsley, chopped for garnish

Instructions

Preparation Steps

  • Heat oven to 350°F. Set a 9x13-inch baking dish nearby.
  • Pat chicken dry. Season all over with salt, pepper, garlic powder, and thyme.
  • Arrange chicken in the dish in a single layer. Cover evenly with Swiss cheese.
  • Whisk soup, sour cream, broth, and Dijon in a bowl until smooth.
  • Pour the sauce over the chicken and cheese, spreading to coat.
  • Toss stuffing with melted butter until moistened. Sprinkle evenly over the casserole.
  • Bake 35–45 minutes, until topping is golden and chicken reaches 165°F. Rest 5 minutes.
  • Scatter parsley over the top and serve warm.

Notes

Variation: Swap the stuffing for 2 cups crushed buttery crackers mixed with 4 tbsp melted butter for a crispier topping. For more depth, replace half the broth with dry white wine. Leftovers keep well, covered, in the fridge for up to 3 days; reheat at 325°F until warm.
