How to Make Crockpot Chicken Reuben Casserole | Easy St Patrick’s Day
Combine Chicken and Seasonings: Start by placing the cubed chicken breasts into your slow cooker. Sprinkle the salt, ground pepper, garlic powder, and caraway seeds evenly over the chicken. Use a spoon (or your clean hands) to mix everything together well, ensuring each piece is seasoned nicely.
Layer on the Sauerkraut: Once the chicken is spiced up, add in the drained sauerkraut. Spread it out in an even layer on top of the chicken. This helps to trap the flavors and moisture as it cooks.
Add Dressing: Now it’s time for the creamy goodness! Pour the Thousand Island dressing over the sauerkraut, and use a spoon to spread it out evenly. This will help infuse the dish with that classic Reuben taste.
Top with Cheese: Finally, lay the Swiss cheese slices over the top of the dish. Don’t be shy—cover it generously! The cheese melds to create that wonderful, gooey texture everyone loves.
Cook to Perfection: Set your slow cooker to low heat and let it cook for 5 hours. You’ll know it’s ready when the chicken is cooked through, the casserole is bubbling around the edges, and you can smell that intoxicating aroma filling your kitchen.

Storing & Reheating
To store any leftovers, let the casserole cool to room temperature and transfer it to an airtight container. Refrigerate 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. Reheating is easy—just pop it in the microwave for a few minutes until warmed through. Keep in mind that the texture may change after freezing, but a quick stir and reheat will do wonders to bring it back to life.
Chef’s Helpful Tips
- Avoid overcooking the chicken to keep it tender—5 hours on low is perfect!
- Room temperature chicken ensures even cooking; take it out of the fridge ahead of time if possible.
- If you like it spicy, add some chopped jalapeños or a dash of hot sauce into the mix.
- Consider adding a layer of crispy breadcrumbs on top for an added crunch.
- Make it ahead of time! Prep the casserole the night before, pop it in the fridge, and turn on the slow cooker in the morning for a hassle-free meal.
These easy tips can help make your casserole turn out perfectly every time and ensure you impress anyone you serve it to!
