I'll show you step by step how to get this easy meal going. If you're in a rush, there's a quick and easy video in the recipe card you can watch for reference.

Ingredients

Chicken breasts: You will need 2 pounds of boneless, skinless chicken breast. Depending on your butcher or size of chickens, that may be anywhere from 4-6 chicken breasts.
Stuffing mix: A 6oz box of stuffing mix is used in this easy Slow Cooker Swiss Chicken Casserole. You can use a homemade version, generic, or the name brand (AKA Stove Top).
Cream of chicken: A single 10oz can is used in this recipe, and makes for a lovely creamy texture. You can definitely use a homemade version if desired.
Swiss cheese: 6 slices of Swiss Cheese top the layer of chicken breasts. You can substitute for approximately 1 - 1 ½ cups of shredded Swiss cheese if desired.
Sour cream: Just a little bit of sour cream helps up the creamy factor of this delicious recipe!
Butter: Everything is better with butter, am I right? I recommend using unsalted butter if possible, since we are using a lot of prepared foods, which tend to have a higher sodium content.

How to make Swiss Chicken Casserole in the Slow Cooker.

Pour the sour cream and soup mixture on top of the chicken breasts, spreading it out evenly with the back of a silicone spatula or spoon.

Sprinkle on the entire contents of a 6oz box of dry stuffing mix, ensuring it is evenly distributed.

Pour ¼ cup of melted butter over the surface of the dry stuffing mix.

Place the lid on the slow cooker and cook on "low" for 5-6 hours, or on "high" for 2 ½-3 hours.

Checking internal temperature

To ensure the chicken is cooked through, use an internal thermometer to check the temperature of each chicken breast. You are looking for a minimal internal temperature of 165F. Serve and enjoy with your favorite side dishes!

Substitutions

Boxed stuffing mix: If you prefer not to use boxed stuffing mix, or can't find it in your local grocery store, you can make your own using this recipe, or you can use 2 cups of prepared homemade stuffing. If you opt for using homemade stuffing, your casserole will be little more wet than if you were to use the dry boxed stuffing. That being said, it will still be delicious!

Cream of Chicken Soup: This easy condensed soup is used to make a quick and comforting sauce for our slow cooker casserole. If you prefer to not use condensed soups, you can try this recipe for Cream of Chicken Soup from The Cozy Cook.

Variations

With wine: If you want to add a little elegance (and a whole lotta flavor!) to this humble comfort food casserole, add ½ cup of your favorite dry white wine to the condensed soup and sour cream before spreading on top of the swiss cheese topped chicken.

With sherry: Add ½ cup of cooking sherry with the condensed soup and sour cream before spreading on top of the chicken and swiss cheese.

With croutons: Substitute the dry stuffing mix for 6oz worth of prepared croutons.
