How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Add Chicken: Start by placing the cubed 2 lbs. boneless skinless chicken breasts into your slow cooker. Season with 1/2 tsp. salt, 1/4 tsp. ground pepper, 1 tsp. garlic powder, and 1/2 tsp. caraway seeds. Use a spoon or your clean hands to mix everything evenly so that the chicken is well-coated.
Layer Sauerkraut: Next, carefully drain the 32 oz. can of sauerkraut to ensure that no excess moisture remains. Spread the sauerkraut evenly over the seasoned chicken, creating a hearty layer that brings a lovely tart flavor.
Add Dressing: Pour 1 cup of Thousand Island dressing over the sauerkraut layer. Use a spatula to spread it evenly, ensuring every nook and cranny gets a taste of that creamy goodness.
Top with Cheese: Slice the 8 oz. of Swiss cheese and lay the slices over the dressing evenly. This melty layer will create that gooey, comforting texture we all love when it comes out of the slow cooker.
Cook: Set your slow cooker on low and let it work its magic for about 5 hours, or until the chicken is fully cooked and bubbling around the edges. You’ll know it’s ready when the cheese is melted and everything looks deliciously gooey.
Serve and Enjoy!: Once completed, give it a gentle stir and scoop out generous portions to serve everyone. This dish is best enjoyed warm and can be paired with fresh bread or a simple side salad.

Storing & Reheating
To store any leftovers, let the casserole cool completely before transferring it to an airtight container. You can keep it at room temperature for up to two hours or refrigerate for up to 3 to 4 days. If you’d like to store it longer, consider freezing it in a freezer-safe container for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the refrigerator and reheat in the microwave or oven at 350°F for about 20-30 minutes, until warmed through. Note that the texture might mellow, so consider adding a splash of additional Thousand Island dressing to freshen it up!
Chef’s Helpful Tips
- Avoid overcooking the chicken by ensuring it is cut into even-sized cubes for uniform cooking.
- When layering, make sure the sauerkraut is well-drained to prevent a watery casserole.
- If you like a bit of a kick, consider adding some diced jalapeños or crushed red pepper flakes.
- Use room temperature ingredients for better mixing. If using cheese, ensure it’s at room temperature for easier melting.
- Feel free to prep this casserole a day in advance. Just store it in the fridge before cooking and then pop it in the slow cooker when ready.
