Ingredients You’ll Need

2 lbs. boneless skinless chicken breasts, cubed: This is the protein base for our casserole. Boneless chicken cooks down beautifully in the slow cooker. Substitute with thighs for more flavor.
1/2 tsp. salt: Enhances the flavors of the dish. Feel free to adjust based on dietary preferences.
1/4 tsp. ground pepper: Adds a mild kick. Freshly cracked pepper offers a stronger flavor.
1 tsp. garlic powder: Provides a warm, aromatic note. Fresh minced garlic can be used, but reduce the amount.
1/2 tsp. caraway seeds: Offers that distinctive Reuben flavor. You can skip these if you’re not a fan or use fennel seeds instead.
32 oz. can sauerkraut, drained very well: Adds that signature tanginess to the dish. Look for high-quality sauerkraut for the best taste.
1 cup thousand island dressing: The creamy element that ties it all together. Use refrigerated dressing for a fresher taste, or make your own for a customizable option.
8 oz. Swiss cheese: Melts wonderfully and complements the dish’s flavors. Gruyère or Monterey Jack can also be delicious alternatives.

How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day

Add Chicken: Start by placing the cubed chicken breasts into your slow cooker. Sprinkle the 1/2 teaspoon of salt, 1/4 teaspoon of ground pepper, 1 teaspoon of garlic powder, and 1/2 teaspoon of caraway seeds over the chicken. Mix thoroughly with either a spoon or your hands to distribute the seasonings evenly.

Layer Sauerkraut: Gently pour the 32 oz. can of drained sauerkraut over the seasoned chicken, spreading it out so that it covers the chicken in an even layer. This helps to create distinct layers of flavor while it cooks.

Spread Dressing: Take your 1 cup of thousand island dressing and carefully spread it over the sauerkraut. No need to stir at this point; just let it sit atop the layers.

Add Cheese: Now it’s time for some cheesy goodness! Lay the 8 oz. Swiss cheese slices evenly over the dressing. This melty layer will add such a comforting texture to the finished casserole.

Cook: Set your slow cooker to low and let it work its magic for 5 hours. The chicken should be cooked through and the mixture bubbling around the edges when it’s ready. Take a moment to enjoy the irresistible aroma wafting through your kitchen!

Serve: Once done, scoop out hearty portions of your Crockpot Chicken Reuben Casserole and dig in. This dish is perfect served on its own or with a side of crusty bread.

Storing & Reheating

To store leftovers, let them cool to room temperature and place them in an airtight container. They’ll keep well in the refrigerator for up to 3 days. If you’re planning to freeze, transfer it to a freezer-safe container, and it’ll last up to 3 months. For reheating, pop it in the microwave for a few minutes or warm it up in the oven at 350°F until heated through. Keep in mind that while freezing may alter some textures, refreshing it with a splash of dressing when reheating can elevate the flavors again.

Chef’s Helpful Tips

Avoid overcooking the chicken, as it may dry out. It should be tender and juicy after slow cooking.
For a creamier texture, consider mixing in a bit of sour cream or cream cheese with the dressing.
Timing can vary depending on your slow cooker model, so keep an eye on the casserole as it nears the end of the cooking time.
If you’d like to add a crunchy topping, throw some crushed crackers or crispy onions on right before serving for added texture.
Feel free to swap out the cheese for cheddar or provolone if that’s what you prefer.

The combination of tender chicken, tangy sauerkraut, and creamy dressing enveloped in melted cheese makes you wonder why you didn’t try making this casserole sooner.

Recipe FAQs

Can I use frozen chicken?

Yes! You can use frozen chicken breasts, but you’ll want to cook the casserole on low for about 7 hours instead of 5. Just make sure the chicken reaches an internal temperature of 165°F.

What can I substitute for Swiss cheese?

If you’re not a fan of Swiss cheese, alternatives like provolone, mozzarella, or even sharp cheddar can add a different twist while still melting well.

How can I adjust this recipe for smaller servings?

If you want to make a smaller portion, simply halve all the ingredients, and adjust the cooking time accordingly—maybe check around the 3-hour mark on low.

Can I make this dish ahead of time?

Absolutely! You can prepare it the night before and store it in the refrigerator, covered, until you’re ready to cook it the next day. Just give it a few extra minutes in the slow cooker.

This Crockpot Chicken Reuben Casserole is not just easy; it’s a feast of flavors that can easily become a staple in your home.
