How to Make Crockpot Reuben Sandwiches
Mix the Rub: Start by combining the brown sugar, coarse black pepper, ground coriander, garlic powder, paprika, and onion powder in a small bowl. This will create a flavorful rub for your corned beef.
Prepare the Corned Beef: Lay the corned beef brisket on a large sheet of aluminum foil. Generously spread the rub mix on all sides. Wrap the corned beef tightly in the foil, then double-wrap it to seal in those savory juices effectively.
Slow Cook: Place the wrapped corned beef into the slow cooker without adding any water. Cover with the lid and set it on LOW. Let it cook for about 7 to 8 hours without peeking—this ensures the meat becomes tender and flavorful.
Rest the Beef: Once the cooking time is up, carefully remove the corned beef from the slow cooker. Keep it wrapped in foil and let it rest on a cutting board for about 20 minutes. This step allows the juices to redistribute back into the meat, enriching its flavor.
Make the Coleslaw: While the beef rests, prepare your coleslaw dressing by mixing together 1 cup mayo, 1 tsp. dijon mustard, 1 tsp. creamed horseradish, 1 tsp. sugar, 2 tsp. apple cider vinegar, some coarse black pepper, and poppy seeds in a bowl. Only toss a small amount with your cabbage, carrots, and onion—keep the rest for later so your slaw stays crisp.
Prepare the Russian Dressing: In a small bowl, mix 1 cup mayo, 1/4 cup ketchup, 2 tsp. finely diced onion, a splash of Worcestershire sauce, and 1/4 tsp. paprika. Set aside to let the flavors meld.
Slice the Corned Beef: Unwrap the rested corned beef, discarding any liquid that escapes. Slice it into thin, even pieces—about 1/4 inch thick.
Brown the Bread: In a skillet over medium heat, add 4 tbsp. butter. Once melted, take your marble rye slices and butter one side of each. Place them in the skillet, butter-side-down, and brown until golden and crisp.
Assemble the Sandwiches: Start with the bottom slice of browned marble rye. Spread a generous amount of the Russian dressing on it. Pile on the sliced corned beef, followed by a slice or two of Swiss cheese. Add a hearty scoop of the prepared coleslaw on top.
Finish Off: Add the top slice of marble rye and secure your sandwich with toothpicks if desired. Cut in half for easier handling.
Enjoy: Serve these flavorful sandwiches warm and watch as your guests come back for seconds!

Storing & Reheating
Store any leftover Crockpot Reuben Sandwiches in an airtight container in the refrigerator for up to three days. For longer storage, you can freeze the sandwiches wrapped tightly in plastic wrap or foil for up to three months. When you’re ready to enjoy them again, thaw in the refrigerator overnight and reheat in a skillet over medium heat or in an oven at 350°F until heated through, approximately 10-15 minutes. Note that the texture may alter slightly after freezing, but a quick reheat should bring back some of that delicious crunch.
Chef’s Helpful Tips
- Ensure your corned beef isn’t too thickly sliced; aim for about 1/4 inch to keep it tender in the sandwich.
- If your dressing is too thick, whisk in a little water or more vinegar for the desired consistency.
- Feel free to toast the marble rye before adding fillings; this adds an extra crunch and prevents sogginess from the toppings.
- Experiment with different types of cheese, such as provolone, if you prefer something different!
- For extra flavor, consider adding pickles or banana peppers to the sandwich before serving.
Crockpot Reuben Sandwiches don’t just taste great; they bring a satisfying warmth that wraps you in layers of flavor and texture with each bite. With minimal preparation and simply a bit of patience, you’ll present an impressive yet incredibly easy meal that invites good times and great company. Feel free to play around with the ingredients or tweak the dressings until they reflect your taste perfectly. I can assure you that once you try this recipe, it will become a beloved favorite you’ll return to time and again. Enjoy every mouthwatering moment!
Recipe FAQs
Can I use a different type of meat for this recipe?
Absolutely! While corned beef provides that classic Reuben taste, you could substitute pastrami or roast beef for a tasty twist. Adjust spices in the rub as needed, depending on your meat choice.
Is there a way to make this recipe healthier?
Definitely! Opt for whole grain or gluten-free bread, and you may also use Greek yogurt instead of mayo for a lighter dressing. Incorporating more veggies in the coleslaw can also increase its nutritional value.
Can I prepare the ingredients ahead of time?
Yes! You can prepare the rub and slice your vegetables the night before. This way, all you’ll need to do in the morning is wrap the corned beef and start it in the slow cooker.
How do I adjust the spiciness in the dressing?
You can control how spicy your dressing gets by adjusting the amount of horseradish used. For a milder flavor, start with a smaller amount and add more as needed—taste testing is key!
