This chicken bake has amazing texture in every bite. The chicken stays nice and juicy while baking under the sauce and cheese. But the best part is the crunchy topping. It turns perfectly golden brown, making the casserole very satisfying.

Another great thing about this recipe is that there are very few dishes to wash at the end of the day.

The Ingredients

Here is everything you need to grab for this classic bake: boneless skinless chicken breasts, slices of Swiss cheese, cream of chicken soup, stuffing mix, and butter.

Boneless Skinless Chicken Breasts

The chicken breasts make this dish lean, but since it is covered in a creamy sauce, the meat won’t taste dry. To ensure that the chicken cooks evenly, pound the breasts to the same thickness or cut large breasts in half horizontally. Boneless skinless chicken thighs are a good alternative.

Swiss Cheese

Swiss cheese adds a nutty and sweet flavor that balances the creaminess of the soup. You should slice the cheese thinly and place it directly on top of the chicken so every bite has some cheesy goodness. Provolone, mozzarella, and white cheddar are also good options if you can’t find Swiss cheese.

Boxed Stuffing Mix

Dry stuffing mix is your best friend when it comes to giving your casserole extra flavor and an ultra-crispy crunch on top. Don’t worry about cooking the stuffing; you simply combine the dry seasoning with melted butter. If you don’t happen to have any stuffing mix on hand, you can also use crushed Ritz crackers tossed with a dash of poultry seasoning.

How to Make It

Here’s how easy this five-ingredient casserole is to put together!

Prep the Chicken

Grease a 9×13-inch baking dish with nonstick cooking spray. Place the chicken breasts in an even layer at the bottom of the dish and sprinkle lightly with black pepper.

Layer the Cheese

Lay the slices of Swiss cheese evenly over the top of the chicken breasts, overlapping them slightly so that all the chicken is covered.

Spread the Soup

Scoop the condensed cream of chicken soup onto the cheese layer. Gently spread the soup over the top with a spoon until the soup forms an even layer.

Add the Topping

Pour melted butter over the dry stuffing mix in a small bowl and toss to coat. Sprinkle the mixture evenly over the soup.

Bake and Serve

Bake uncovered in a 350°F oven for 45-50 minutes, or until the chicken is cooked through and the topping is browned. Let stand for a few minutes before serving so the sauce thickens slightly.

My Best Tips for Success

For tender, juicy chicken every time, take two minutes to pound the chicken breasts to an even ½-inch thickness before placing them in the pan. If you skip this step, the thin ends of the breasts will cook too quickly and become dry and tough before the thicker parts are done.

If the condensed soup seems too thick to spread after opening the can, stir in a bit of milk to thin it out. This will help make it easier to spread evenly over the cheese without breaking it up. You want the soup to spread easily, but not be too thin.

Don’t cover this casserole while it bakes! Allowing the casserole to remain uncovered lets the buttery stuffing on top toast up and get crispy. Covering it will cause the stuffing to become soggy.

Storage and Reheating

• To Store: Cool the casserole completely, then cover the dish with plastic wrap and refrigerate for up to 3 days.
• To Freeze: Freeze tightly wrapped in foil for up to two months. Note that the stuffing topping will become soft upon thawing.
• To Reheat: Bake individual portions in a 350°F oven until heated through or microwave portions if you don’t care about the crisp topping.

What to Serve with This Casserole

• Steamed broccoli florets or buttered green beans. 
• A simple garden salad with a light vinaigrette. 
• Sweet glazed carrots roasted with just a hint of brown sugar.
• A little bit of cranberry sauce on the side.

Frequently Asked Questions

Can I use cream of mushroom soup instead?

Yes, cream of mushroom or even cream of celery soup will work great and give this casserole a whole new flavor. Use what you have on hand.

How do I know when the chicken is done?

You want to make sure the internal temperature of the chicken is 165°F to ensure it is safe to eat. You can use a meat thermometer to test this.

Can I assemble this ahead of time?

Yes, you can layer the chicken, cheese and soup and keep it in the refrigerator overnight. Just hold off on adding the stuffing topping until right before baking so it doesn’t become soggy.
