Reasons I Love This Recipe
There’s something about Crock Pot Corned Beef Reuben Sliders that feels like the best kind of shortcut meal to me. You get all those classic Reuben flavors—savory corned beef, tangy sauerkraut, melty Swiss cheese, and that unmistakable dressing—but in a way that’s easy to make and even easier to serve. I love recipes like this because they take something that can feel a little “special occasion” and turn it into something a home cook can actually pull off without a lot of stress.
XO,
What Is Corned Beef?
It’s a salt-brined beef brisket that gets its name from the large salt crystals used to make it. They are nicknamed “corn” salt because they resemble corn kernels, hence the name “corned beef.” It became associated with St. Patrick’s Day because Ireland was the largest producer of corned beef, owing to its low salt tax and large cattle ranches.
Make-ahead party sliders are always fun to serve! Other family favorites are Crockpot Mississippi Sliders and Roast Beef and Cheese Sliders.
What You Need To Make Reuben Slider Sandwiches
Crock Pot Corned Beef Ingredients
- Slow Cooker Corned Beef—You must make corned beef brisket in the crockpot. You’ll need 3-4 lbs of brisket.
- Vegetables—To add heartiness to the dish, you will need an onion, carrots, celery, and garlic.
- The flavor -For that delicious Irish flavor add beef broth, tomato paste, Worcestershire sauce, brown sugar, and the secret ingredient – dark beer! Any dark beer you like will work, but Guinness is the best.
- Spices – You will need celery seeds, red pepper flakes for a kick, salt, and fresh cracked pepper. Fresh cracked black pepper has so much more flavor than ground pepper!
Slider Ingredients
- The dressing: For my homemade Thousand Island dressing, you need mayonnaise, ketchup, chili sauce, sweet pickle relish, and salt and pepper to taste.
- Slider buns – I love to use Hawaiian rolls because they are soft, delicious, and slightly sweet so everyone loves them. Any slider buns will work, though; just slice through them horizontally for easy assembly.
- Swiss cheese slices.
Change It Up: Variations And Additions
These Irish corned beef sliders have a ton of great flavor that is pretty specific to the Reuben, but you can switch up a few things as needed.
- Try sliced white cheddar if you don’t have Swiss cheese.
- If you don’t want to make the corned beef brisket, you can substitute pastrami or deli corned beef in a pinch.
- Add horseradish to the Thousand Island dressing. This makes it technically Russian dressing.
How To Make Reuben Sliders In The Slow Cooker
- Layer the slow cooker with ½ of the chopped veggies, the corned beef (fat side up), the remaining vegetables, and garlic.
- In a bowl, mix the spices and wet ingredients and then pour it over the beef. Sprinkle salt and pepper on top, really coat it well! Then pour in your dark beer and cook on low for 8 hours.
- After cooking, remove the brisket and shred it with 2 forks. Mix all the ingredients in a small bowl to make the Thousand Island dressing.
- Slice the slider buns horizontally and layer the corned beef, Swiss cheese, dressing, and the top buns. Lastly, add melted butter and fresh chopped parsley to the top of the rolls and serve.

Donya’s Success Tips
- Assemble the sandwiches while the beef is hot so the cheese slices melts nicely.
- When pulling out the shredded corned beef, let as much liquid drain out or off as possible. This keeps the sliders from getting soggy.
- If you are short on time, you can use store-bought or leftover corned beef. Layer the sandwiches and then bake them in the oven covered with foil for just enough time to heat the beef and melt the cheese.

Questions And Answers
Yes. You can cook the corned beef ahead of time and refrigerate it until you’re ready to assemble the sliders. You can also assemble the sliders a few hours in advance, cover them, and bake when ready to serve.
Soft Hawaiian rolls or slider buns work especially well because they hold together nicely and bake up golden on top. If you want a more classic deli-style flavor, regular slider buns are also a great option.
Both sandwiches are layered deli meat with Thousand Island dressing on rye bread. But, a Rachel uses cabbage instead of sauerkraut and sometimes swaps turkey for the corned beef.
Yes, you can use store-bought but the best flavor will come from homemade dressing!
Yes, it’s a good idea to drain the sauerkraut well before adding it to the sliders but you don’t need to rinse it. This helps keep the rolls from getting soggy and gives you the tangy flavor without too much extra moisture.
What to Serve With The Best Corned Beef Reuben Sliders
I love to serve them with my Million Dollar Dip, Quick Pickled Red Onions (also good on the sliders!), and Creamy Southern Deviled Eggs. For a St. Patrick’s Day dinner party, I love to serve them with Beer Cheese Dip, Baked Potatoes and Fried Cabbage and Bacon.
