Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x13 inch baking dish.
Arrange chicken breasts in the baking dish. Place one slice of Swiss cheese on top of each chicken breast. Combine cream of chicken soup and milk in a medium bowl, and pour over chicken breasts. Sprinkle with stuffing mix. Pour melted butter over top, and cover with foil.
Bake 50 minutes, or until chicken is no longer pink and juices run clear.
Melted Swiss cheese bubbles around tender chicken breasts while a buttery, seasoned stuffing crust bakes to a crisp golden brown on top. Adapting this assembly for larger or smaller groups requires careful attention to pan dimensions.
Adjusting Yields for Any Crowd
Halving the ingredients fits neatly into an 8x8-inch baking dish without altering the 350 degrees F oven setting. Doubling the batch demands a transition to two separate pans rather than one oversized container, ensuring the heat circulates evenly around every piece of poultry. Stacking meat too thickly prevents the center portions from reaching the required internal safety threshold of 165 degrees F before the surface browns excessively.
Managing Kitchen Workflow
Prepping components in a specific sequence prevents operational bottlenecks on busy cooking days. Whisking the condensed cream of chicken soup and milk together in a medium bowl should happen before arranging the poultry in the greased 9x13-inch dish. Pouring that dairy mixture directly over the cheese-topped meat creates a moisture barrier that keeps the protein juicy during the extended baking duration. Dry bread stuffing mix goes on next, absorbing excess liquid released by the baking chicken.
Butter Distribution and Storage
Drizzling the melted butter uniformly across the dry stuffing mix guarantees proper hydration and prevents patchy, scorched areas on the crust. Covering the dish tightly with aluminum foil for the initial phase traps steam, allowing the meat to cook thoroughly before the top browns. Leftovers retain quality when stored in an airtight container in the refrigerator for up to three days, though reheating must be done gently at 300 degrees F to prevent the poultry from toughening.
