How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Add Chicken: Begin by placing 2 lbs. of cubed boneless skinless chicken breasts in your slow cooker. Sprinkle over 1/2 tsp. salt, 1/4 tsp. ground pepper, 1 tsp. garlic powder, and 1/2 tsp. caraway seeds. Use your clean hands or a spoon to combine the chicken with these seasonings, ensuring each piece is well-coated with flavor.
Layer Sauerkraut: Drain your 32 oz. can of sauerkraut very well—you want to avoid a soupy texture in your casserole. Spread the drained sauerkraut evenly over the chicken in the slow cooker for that essential tangy crunch.
Spread Dressing: Next, pour 1 cup of thousand island dressing over the sauerkraut layer. Don’t be shy; spoon it on in an even layer and take a moment to enjoy the vibrant colors that start to appear.
Add Cheese: Now for the delicious finale—layer 8 oz. of Swiss cheese slices over the top of the dressing. Make sure to cover it all; the cheese will melt beautifully as the casserole cooks, resulting in a creamy topping.
Cook: Set your slow cooker to low for 5 hours. The dish is ready when the chicken is cooked through and the casserole is bubbling around the edges. You’ll know it’s time to serve when your kitchen is filled with mouthwatering scents.

Storing & Reheating
Store any leftover Crockpot Chicken Reuben Casserole in an airtight container in the fridge for up to three days. For longer storage, transfer the casserole into a freezer-safe container for up to three months. To reheat, simply thaw overnight in the refrigerator and warm in the microwave or oven at 350°F for about 20 minutes, or until heated through. Just keep in mind that the texture might change slightly, so a quick stir can help bring that comforting creaminess back.
Chef’s Helpful Tips
