Creamy Swiss Chicken Casserole is a simple, comforting dinner the whole family will enjoy. With only six basic ingredients, this juicy chicken bake is ideal for busy weeknights and makes excellent leftovers or freezer meals.
This oven-baked version of my popular slow-cooker Swiss chicken casserole is quick to assemble and bakes into a creamy, cheesy dish topped with crunchy stuffing mix. It’s a cozy, satisfying meal that’s been a family favorite for years.
Reasons to Love This Recipe:
- Easy to make. Layer the ingredients, bake, and serve—perfect for hectic evenings.
- Beginner-friendly. Minimal prep and straightforward steps yield impressive results.
- Freezes well. Assembled unbaked or cooked portions freeze and reheat beautifully.
- Versatile. Use chicken breasts, thighs, tenders, or shredded rotisserie chicken.
Ingredients
- Chicken: Boneless, skinless chicken breasts are recommended; smaller breasts or pounded pieces cook faster. Skinless thighs also work.
- Dry stuffing mix: A 4–6 oz box (Stove Top or your preferred brand).
- Cream of chicken soup: Provides a creamy base. Cream of mushroom or a homemade condensed soup can be substituted.
- Swiss cheese: Slices melt well and add a mild, nutty flavor; mozzarella or provolone can be used instead.
- Sour cream: Adds creaminess and a touch of tang to the sauce.
- Butter: Melted and drizzled over the stuffing for a golden, rich topping.
Equipment
- Casserole dish: A medium or large baking dish works. Size affects layer thickness and baking time.
- Meat thermometer: Use to confirm the thickest part of the chicken reaches 165ºF (74ºC).
Instructions
This casserole combines juicy chicken, a creamy sauce, and a seasoned stuffing topping for an easy, comforting meal.
Step one: Preheat the oven to 350ºF (177ºC) and lightly grease a medium baking dish (such as 7.5 x 10″ or 9 x 9″).
Step two: Add the condensed cream of chicken soup and sour cream to a small bowl and stir until smooth.
Assembling
Step three: Place chicken breasts in a single layer in the prepared baking dish. Season lightly with salt and pepper or your preferred seasoning. (Optional: Pound breasts to even thickness for faster, more even cooking.)
Step four: Spread the soup and sour cream mixture evenly over the chicken.
Tip: You can layer cheese and sauce in the order you prefer, but aim for even coverage so each piece melts and bakes uniformly.
Swiss Cheese Layer
Step five: Lay slices of Swiss cheese across the soup layer so the cheese covers the chicken evenly.
Step six: Sprinkle the dry stuffing mix over the cheese in an even layer.
Note: Mild cheeses work best here. Use at least one slice per breast and spread it evenly for consistent melt and texture.
The Stuffing Layer
Step seven: Spread the dry stuffing mix evenly across the top of the cheese.
Step eight: Drizzle the melted butter over the stuffing to help it crisp and brown while baking.
Baking and Serving
Step nine: Cover the dish with foil and bake at 350ºF (177ºC) for 50–80 minutes, depending on the thickness of the chicken. Uncover halfway through baking. The chicken is done when the thickest part reaches 165ºF (74ºC).
Step ten: Let the casserole rest 5–10 minutes before serving. Portion and serve with your favorite sides.
Storing Leftovers + Freezing
Storage: Refrigerate leftovers in an airtight container for up to 3 days.
Reheating: Reheat portions in the microwave or place in a baking dish with 1 tablespoon of water and bake at 350ºF for 20–30 minutes, until heated through.
Freezing: Assemble the dish unbaked for a freezer meal, cover and label, then freeze. Thaw overnight in the fridge before baking, and add 15–25 minutes to the bake time. Cooked leftovers also freeze well—reheat from thawed or frozen, adjusting time accordingly.
What to Serve with Chicken and Stuffing Casserole

Variations
- Seasoning: Add garlic powder, onion powder, paprika, seasoned salt, or sage to the chicken or sauce for extra flavor.
- With wine or sherry: Stir ½ cup dry white wine or cooking sherry into the soup-and-sour-cream mixture for added depth.
- Crouton topping: Replace the dry stuffing mix with about 6 ounces of packaged croutons for a different crunch.
Substitutions
- Gluten-free: Use a gluten-free cream of chicken soup and gluten-free stuffing mix.
- Chicken: Substitute boneless skinless thighs or shredded rotisserie chicken for quicker prep.
- Boxed stuffing mix: Use homemade prepared stuffing (about 2 cups) if preferred; this will produce a moister topping than dry mix.
