Ingredients Notes

The beauty of this Swiss Chicken Casserole is in its simple ingredients, each adding to the creamy, cheesy goodness of the dish. Let’s take a closer look at what you’ll need.

Chicken – You can use boneless, skinless chicken breasts or thighs, cooked and shredded. Rotisserie chicken is a fantastic shortcut, adding extra flavor while saving time.

Swiss Cheese – This cheese gives the dish its signature tangy, nutty flavor. If you prefer something milder, you can substitute with provolone or mozzarella, but Swiss really makes this dish shine.

Cream of Chicken Soup – A can of cream of chicken soup forms the base of the creamy sauce. If you want a homemade touch, you can use a mix of heavy cream and chicken broth instead.

Sour Cream – This adds extra creaminess and a slight tang to balance the richness of the dish. Greek yogurt is a good alternative if you’re looking for a lighter option.

Crushed Crackers – Buttery Ritz crackers create a golden, crispy topping that contrasts beautifully with the creamy filling. If you don’t have Ritz, panko breadcrumbs or buttered cornflakes work well too.

Butter – Melted butter helps bind the cracker topping together and adds a delicious richness. It’s what makes that crispy topping so irresistible!

No special equipment is needed for this recipe—just a mixing bowl, a baking dish, and an oven to bring everything together.

How To Make This Swiss Chicken Casserole

Making this Swiss Chicken Casserole is as easy as layering a few ingredients and popping it in the oven. Here’s how to do it step by step.

Start by preheating your oven to 350°F (175°C). While it heats up, grab a 9x13-inch baking dish and give it a quick coat of nonstick spray to prevent sticking.

Next, arrange your cooked, shredded chicken evenly across the bottom of the baking dish. If you’re using fresh chicken breasts, you can quickly sear them in a pan and slice them before layering.

Now, it’s time to make the creamy sauce. In a mixing bowl, whisk together the cream of chicken soup and sour cream until smooth. Pour this mixture over the chicken, spreading it out evenly so every bite is coated in rich, velvety goodness.

Lay slices of Swiss cheese over the sauce, covering the entire surface. This layer will melt into a gooey, cheesy blanket as the casserole bakes.

For the topping, crush Ritz crackers into small crumbs and mix them with melted butter. Sprinkle this mixture evenly over the top, creating that crispy, golden crust that makes this casserole so irresistible.

Bake uncovered for 30-35 minutes, or until the cheese is bubbly and the topping is a deep golden brown. Let it rest for a few minutes before serving—this helps everything set up so you get perfect, creamy spoonfuls.

Storage Options

This Swiss Chicken Casserole is just as good the next day, making it a great option for leftovers. Here’s how to store it properly.

For the refrigerator, let the casserole cool completely before transferring it to an airtight container. It will stay fresh for 3-4 days—just reheat individual portions in the microwave for a quick meal.

If you want to freeze it, you have two options: freeze before baking or after. To freeze before baking, assemble the casserole but don’t add the cracker topping. Wrap the dish tightly in plastic wrap and foil, then freeze for up to 3 months. When ready to bake, let it thaw overnight in the fridge, add the topping, and bake as directed.

For freezing after baking, portion the casserole into airtight containers and freeze for up to 2 months. Reheat in the oven at 350°F until warmed through, or use the microwave for quicker reheating.

Variations and Substitutions

One of the best things about this recipe is how easy it is to customize. Here are a few ways to switch it up to suit your taste.

Add Vegetables – Mix in some broccoli, peas, or mushrooms for added color and nutrition. Just steam them lightly before adding to prevent excess moisture.

Use Different Cheeses – While Swiss is the star, you can mix it with cheddar, Gouda, or Monterey Jack for a different flavor profile.

Make It Spicy – Add a bit of heat by mixing in red pepper flakes or a few dashes of hot sauce to the creamy sauce.

Swap the Crackers – If you don’t have Ritz crackers, try using French-fried onions, stuffing mix, or even crushed potato chips for a fun twist.

Low-Carb Version – Skip the crackers and use crushed pork rinds or almond flour mixed with butter for a keto-friendly topping.

No matter how you make it, this Swiss Chicken Casserole is bound to become a family favorite. It’s comfort food at its best—creamy, cheesy, and irresistibly crunchy on top. Try it out for your next dinner, and watch it disappear before your eyes!
