How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Add Chicken: Begin by placing the cubed chicken breasts into your slow cooker. Sprinkle the 1/2 tsp. salt, 1/4 tsp. ground pepper, 1 tsp. garlic powder, and 1/2 tsp. caraway seeds evenly over the chicken. Give it a gentle stir with a spoon or mix it up with clean hands to ensure that the seasonings coat the meat well.
Layer Sauerkraut: After seasoning, take your 32 oz. can sauerkraut (drained very well) and layer it over the seasoned chicken. Make sure the sauerkraut is evenly spread to guarantee every bite is full of flavor.
Spread Dressing: Next, generously dollop 1 cup thousand island dressing over the sauerkraut. Spread it out to create a luscious top layer that will meld everything together as it cooks. This is where the magic starts to happen!
Top with Cheese: Now, it’s time to add the final touch. Lay 8 oz. of Swiss cheese slices evenly on top of the dressing, making sure to cover the entire casserole. The cheese will transform into a creamy, bubbling topping once cooked.
Cook: Set your slow cooker to low and cook the casserole for 5 hours. The dish is ready when the chicken is cooked through and everything is bubbling. Keep an eye on it towards the end, the aroma will be heavenly!

Storing & Reheating
You can store any leftovers at room temperature for a maximum of 2 hours. For longer storage, transfer the casserole into an airtight container and refrigerate for up to 3 days. If you have more leftovers, you can freeze the casserole for up to 3 months. When reheating, simply pop it in the oven at 350°F for about 20-25 minutes or until heated through. Do note that textures may change slightly after freezing, but a splash of dressing can help refresh it upon reheating.
Chef’s Helpful Tips
- To avoid dry chicken, ensure you don’t overcook the casserole—check for doneness at the 4.5-hour mark.
- If you’re using fresh garlic instead of garlic powder, remember that about 1 clove equals 1/8 tsp of powder.
- Layering the ingredients well helps flavors meld together. Take care to not overmix while stirring in the first step.
- For an extra crispy topping, you can finish off the casserole under the broiler for a couple of minutes. Just keep an eye on it!
- Adding some chopped fresh parsley as a garnish before serving gives a fresh pop of color and flavor.
