Prep and assemble
- Preheat oven to 375°F (190°C). Set up a 9×13-inch baking dish on a sheet pan for easy handling.
- Lightly grease a 9×13-inch baking dish. Arrange the chicken breasts in the baking dish in an even layer.
- Season the chicken breasts with garlic powder, onion powder, paprika, and black pepper. Make sure each breast gets an even dusting.
- Place two slices of Swiss cheese over each chicken breast. Cover the top so the cheese melts into the chicken.
- In a bowl, whisk together cream of chicken soup, sour cream, and chicken broth until smooth. The sauce should look creamy and pourable.
- Pour the sauce evenly over the chicken. Pour around and over the breasts so the casserole stays moist.
- Combine seasoned stuffing mix and melted butter. Mix until the stuffing looks evenly coated.
- Sprinkle the stuffing mixture over the casserole. Distribute it evenly to form a golden top layer.
Bake and finish
- Cover with foil and bake for 30 minutes at 375°F (190°C). You should see bubbling around the edges while the top remains covered.
- Remove the foil and bake for an additional 15–20 minutes at 375°F (190°C). Bake until the topping is golden and bubbly.
- Garnish with fresh parsley before serving. Add it right at the end for a bright green finish.
Notes
Pro tip: For a more even melt and sauce penetration, keep the chicken breasts in a single layer with slight gaps rather than tightly packed. Refrigerate leftovers in a covered container for up to 3 days; reheat in the oven at 350°F (175°C) until hot. Freezing is not recommended because the sour-cream sauce can break after thawing. For a lighter option, swap sour cream for plain low-fat Greek yogurt (same amount) to keep the sauce creamy.
