How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Prepare the Chicken: Begin by adding the cubed chicken breasts to your slow cooker. Sprinkle the 1/2 teaspoon of salt, 1/4 teaspoon of pepper, 1 teaspoon of garlic powder, and 1/2 teaspoon of caraway seeds over the chicken. Use your hands or a spoon to mix this delicious blend, ensuring each piece of chicken is seasoned for peak flavor.
Layer the Sauerkraut: Drain the 32 oz. can of sauerkraut thoroughly—this step is crucial to avoid excess liquid spoiling the texture. Once drained, add it over the seasoned chicken in an even layer. The sauerkraut’s tangy crunch is sure to complement the chicken perfectly.
Add the Dressing: Next, spread 1 cup of Thousand Island dressing evenly over the sauerkraut. This dressing is the secret ingredient that brings everything together, enhancing the flavors in a fabulous way!
Top with Cheese: Now for the best part: add 8 oz. of Swiss cheese slices over the dressing. Make sure to cover as much surface area as possible; we want every bite to be cheesy!
Cook to Perfection: Cover your slow cooker and set it to cook on low for 5 hours, allowing the casserole to bubble and the chicken to reach that perfect cooked-through point. You’ll know it’s ready when your kitchen fills with an aromatic scent and everything is nicely bubbling at the edges.
Serve and Enjoy: Once the casserole is done, ladle it out, and serve it hot! Honestly, you’ll have a hard time waiting for it to cool down. It’s perfect as a main dish or alongside some crispy bread.

Storing & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. If you want to keep it longer, consider freezing it in a freezer-safe container for up to 3 months. Reheat portions in the microwave, heating in intervals of 1-2 minutes until warm. Just a note: while the flavors will still be delightful, the texture may soften once stored; you can brighten it up with a sprinkle of fresh herbs when serving.
Chef’s Helpful Tips

- For a creamier texture, consider mixing in some sour cream or cream cheese.

Recipe FAQs
Can I use a different type of cheese?
Yes, absolutely! While Swiss cheese creates that classic Reuben vibe, you can easily swap it for cheddar or even a pepper jack for a spicy twist.
How can I make this dish vegetarian-friendly?
To create a vegetarian version, substitute the chicken with chickpeas or tempeh for protein, and maintain the same layering technique. The rest of the ingredients will work perfectly as is!
Is it possible to use fresh sauerkraut?
Yes, fresh sauerkraut can be used in place of canned. Just ensure you drain it properly to avoid excess moisture that can affect the casserole.
Can I cook this on high instead of low in the slow cooker?
You can, but I recommend cooking it on low for the best texture and flavor enhancement. If you’re short on time, cooking on high may take about 2-3 hours; just keep an eye on it!
