How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Add Chicken: Begin by placing the 2 lbs. of cubed boneless skinless chicken breasts in your slow cooker. Sprinkle with 1/2 tsp. of salt, 1/4 tsp. of ground pepper, 1 tsp. of garlic powder, and 1/2 tsp. of caraway seeds. Gently stir to coat the chicken evenly with the spices, using clean hands or a spoon for mixing.
Layer Sauerkraut: Next, take the 32 oz. can of well-drained sauerkraut and spread it evenly over the seasoned chicken. This layer is essential; you want to ensure the sour flavors get trapped in and infuse the casserole.
Spread Dressing: Pour 1 cup of Thousand Island dressing over the sauerkraut layer. No need to be shy; it adds moisture and flavor that brings everything together. Use a spatula to gently spread it out for even coverage.
Add Cheese: On top of the dressing, layer 8 oz. of Swiss cheese evenly across the casserole. The cheese will melt during cooking, creating a luscious, creamy topping that pulls the entire dish together.
Cook Low & Slow: Cover your slow cooker and set it to low for 5 hours. You’ll know it’s ready when the chicken is fully cooked through and the casserole is bubbling around the edges. The fragrant aroma will have everyone in your home eagerly anticipating mealtime.
Serve & Enjoy: Once ready, give it a gentle stir before serving. The casserole is perfect on its own or served with a simple side salad for a complete meal. Dig in and enjoy the comforting flavors!

Storing & Reheating
Any leftovers of this delicious casserole can be stored at room temperature for up to two hours after cooking. For longer storage, transfer to an airtight container and refrigerate, where it will stay fresh for up to four days. If you choose to freeze, portion the leftovers in freezer-safe bags or containers, ensuring they lie flat for easy stacking, and enjoy within three months for the best flavor. When ready to reheat, warm it in the microwave for about 3-5 minutes, just until heated through. The texture may change slightly upon freezing, but a quick stir and a splash of dressing can refresh that creamy goodness.
Chef’s Helpful Tips
- Always drain the sauerkraut thoroughly to avoid excessive liquid in your casserole.
- Use room temperature chicken for more even cooking; this can help in ensuring that it cooks through without drying out.
- For a creamier texture, consider incorporating cream cheese alongside the Swiss for an extra indulgent rendition.
- Experiment with different cheeses to find your personal favorite twist.
- Adding fresh chopped herbs like parsley or dill at the end can brighten up this comforting dish.

Recipe FAQs
Can I use frozen chicken breasts in this recipe?
Yes, you can use frozen chicken breasts, but be aware that cooking time may need to be extended. Ensure the internal temperature reaches 165°F to guarantee doneness.
Can I substitute the Thousand Island dressing?
Absolutely! If Thousand Island dressing isn’t your favorite, consider using a creamy ranch or a homemade vinaigrette for a different flavor profile.
How spicy is this dish?
This casserole is not spicy, making it a family-friendly option. If you love a kick, try adding sliced jalapeños or a dash of hot sauce into the layers for a spicier take!
Can I keep this dish warm in the slow cooker for longer than 5 hours?
While you can keep it on the warm setting after it has cooked, be cautious not to exceed a couple of hours. Overly extended warming can dry out the chicken.
