- 32 oz. can sauerkraut, drained very well: The star ingredient that provides tanginess; make sure to drain it thoroughly to avoid excess moisture.
- 1 cup Thousand Island dressing: Creamy and tangy, this dressing ties everything together. The refrigerated kind is fresher and more flavorful.

How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Add Chicken & Seasonings: Begin by tossing 2 lbs. of cubed boneless skinless chicken breasts into 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 hands or a spoon to combine everything nicely, ensuring the chicken is well-coated in seasoning.
Layer Sauerkraut: Once the chicken is evenly seasoned, add in the 32 oz. can of drained sauerkraut. Spread it out over the chicken in an even layer, making sure to cover it completely for maximum flavor absorption during cooking.
Spread the Dressing: Next, take 1 cup of Thousand Island dressing and spread it generously over the sauerkraut layer. This dressing will enrich your casserole with creamy goodness that complements the other ingredients perfectly.
Add Cheese: Finally, Top off your creation by adding 8 oz. of Swiss cheese slices evenly over the dressing. Those little pockets of melted cheese will create a delicious crust on top.
Cook to Perfection: Cover your slow cooker and set it to low for 5 hours. This slow cooking method allows the flavors to meld beautifully, and you’ll know it’s ready when the casserole is bubbling and the chicken is fully cooked through.

Storing & Reheating
Store any leftovers in an airtight container, where they will keep in the fridge for up to 3 days. If you’d like to savor this dish longer, you can freeze it for up to 3 months. Just be sure to cool it completely before transferring to a freezer-safe container. When you’re ready to enjoy it again, reheat in the microwave or oven until thoroughly warmed, about 20-30 minutes at 350°F. Note that the texture might slightly change, but you can refresh the dish by adding a splash of additional Thousand Island dressing.
Chef’s Helpful Tips
- Avoid overcooking the chicken; it should be just right to retain moisture and tenderness.
- For a creamier texture, consider adding a bit of cream cheese while it’s cooking.
- To keep things fresh, add some chopped fresh herbs, like parsley or dill, just before serving!
- If you want a crunch on top, pop it under the broiler for a few minutes, but monitor closely to avoid burning.
- Make this dish ahead of time by prepping everything the night before, then cooking it in the slow cooker in the morning.
This Crockpot Chicken Reuben Casserole is not only a delicious triumph of flavors, but it’s also incredibly adaptable. Don’t hesitate to switch up the ingredients or play with spices according to your taste preferences!
Recipe FAQs
Can I make this recipe with turkey instead of chicken?
Absolutely! Ground turkey or turkey breast would work beautifully as a substitute for the chicken. Just ensure to monitor the cooking time, as ground turkey tends to cook faster.
Can I use different types of cheese?
Of course! While Swiss cheese is traditional, you can switch it out for varieties like provolone, Gouda, or even a sharp cheddar. Each cheese will bring a unique flavor profile to the casserole.
How can I make this dish gluten-free?
To make this recipe gluten-free, ensure your Thousand Island dressing and sauerkraut do not contain gluten. Most brands are gluten-free, but always double-check the labels!
Can I cook this on high instead of low?
Yes; if you’re short on time, you can cook this casserole on high for approximately 3 hours. Just keep an eye on it and check that the chicken is fully cooked through before serving.
