Sliders are my go-to appetizer: handheld, cheesy and full of flavor. With big sports events and gatherings coming up, these Reuben sliders are a crowd-pleasing choice. Instead of deli slices, this recipe uses slow-cooked corned beef brisket for a richer, fresher Reuben experience.

Ohio is home to more than 17,000 beef farming families, with cattle in every county. Most beef farms are family owned, and using locally raised beef supports those communities.

Why You Will Love These Reuben Sliders:

  • Fresh slow-cooked corned beef: Freshly cooked and thinly sliced corned beef beats deli meat every time—juicy, flavorful and tender when cooked low and slow.
  • Minimal ingredients: Corned beef, slider rolls (Hawaiian rolls work great), sauerkraut, Swiss cheese, Russian or Thousand Island dressing and melted butter for the tops. Simple and satisfying.
  • Easy to make: Apart from the slow-cooking time, assembly is quick: layer the ingredients on split rolls, brush with butter and bake until the cheese melts.
  • Perfect party food: These give classic Reuben flavors in an easy-to-serve slider format—ideal for game day or any get-together.

Recipe Ingredients:

  • Corned beef brisket: Comes with a spice packet and is ideal for slow cooking. The brisket yields tender slices or shredded pieces perfect for sliders.
  • Beef broth: Low-sodium broth is recommended; water or beer can also be used to adjust flavor.
  • Hawaiian or slider rolls: Their pull-apart packaging makes assembly easy, but any slider buns will work.
  • Swiss cheese: Mild and melty—provolone or gruyere are good alternatives.
  • Sauerkraut: Drain well to avoid soggy rolls.
  • Dressing: Russian dressing is traditional; Thousand Island is a similar and tasty option.
  • Butter: Melted and brushed on top of the rolls before baking for a golden finish.

What Exactly is Corned Beef?

Corned beef is beef, typically brisket, cured in a salt solution—historically a preservation technique before refrigeration. The term “corned” refers to the coarse “corns” of salt used in the curing process. Because it’s usually brisket, slow, low heat yields the best tender, juicy results for sandwiches or holiday dinners.

How to Make These Corned Beef Sliders

Slow cooking the corned beef on low heat is the key to tender, sliceable meat. Place the corned beef brisket fat-side up in a crock pot, pour in beef broth, and sprinkle the included spice packet over the meat. Cook on low for 8–10 hours or until fork-tender. While safe to eat at 145°F, longer cooking helps break down the brisket connective tissue for melt-in-your-mouth texture.

When cooked, remove the brisket, let it rest for about 5 minutes, trim excess fat and slice thinly—around 1/4 inch—or pull apart into slightly shredded pieces if you prefer.

Preheat the oven to 350°F. Slice the slider rolls in half horizontally but keep the tops connected if possible. Place the bottom halves in a greased 9×13 baking dish or on a lined sheet pan.

Layer the bottom with sliced corned beef (two thin slices per slider is a good guideline), then add drained sauerkraut. Top with 6–8 slices of Swiss cheese—enough to cover the sandwiches. Spread Russian or Thousand Island dressing on the inside of the top roll layer, place the tops on, and brush generously with melted butter.

Cover the pan with foil and bake for about 25 minutes, or until the cheese is fully melted. For a browned top, remove the foil for the last few minutes. Let the sliders rest a few minutes before cutting. Insert toothpicks to keep each slider intact and finish with a sprinkle of chopped parsley.

Chef’s Tips

  • Prep the meat ahead: Cook the corned beef a day in advance if needed. Wrap tightly in foil and refrigerate, then slice before assembling sliders.
  • Layer to avoid soggy buns: Place cheese over the sauerkraut to form a barrier between the kraut and the bread.
  • Any slider rolls will work: Hawaiian rolls are convenient, but use your preferred slider buns. If rolls are already separated, arrange them close together on the pan.
  • Use toothpicks: After slicing, toothpicks help keep the melty sandwiches together for easy serving.

What to Serve With These Reuben Sliders

These sliders fit any party spread—game day, birthdays or casual get-togethers. For a heartier meal, serve with potato wedges. For a party buffet, add nachos, caprese skewers, chips and dip, or puff pastry bites to round out the selection.

Choose a drink that can stand up to beef-forward flavors: richer beers or fuller-bodied beverages complement this sandwich well.

Ingredients

For the Corned Beef:

  • 3 lb corned beef with spice packet
  • 1½ c beef broth (low sodium recommended)

For the Reuben Sliders:

  • 12 Hawaiian rolls or slider rolls
  • 6–8 slices Swiss or other melty white cheese
  • 2 c sauerkraut, excess liquid drained
  • 1/3 c Thousand Island or Russian dressing
  • 2 T butter, melted

Instructions

Slow Cooker Corned Beef:

  • Add the corned beef brisket to the crock pot fat-side up. Pour the beef broth over top and sprinkle the included spice packet over the meat. Cook on low for 8–10 hours or until fork tender.
  • Remove the brisket and let rest 5 minutes before slicing thinly (about 1/4 inch) or pulling slightly apart for a shredded texture.

Assembling the Sliders:

  • Preheat oven to 350°F. Grease a 9×13 inch pan or line a sheet pan. Slice rolls in half horizontally and place the bottom halves in the pan.
  • Top bottoms with sliced corned beef, squeezed/drained sauerkraut, and cheese. Spread dressing on the inside of the top rolls and place them on top. Brush with melted butter.
  • Cover with foil and bake about 25 minutes, until cheese is melted. Remove foil for a few minutes to brown the tops if desired. Cool slightly, slice, and serve with toothpicks.

Notes

  • Make ahead: Cook the corned beef the day before, wrap tightly in foil, refrigerate and slice when ready to assemble.
  • Layering matters: Placing cheese over the sauerkraut helps prevent soggy buns.
  • Roll options: Any slider rolls work—arrange separated rolls close together or assemble individual sliders.
  • Use toothpicks: They help keep sliders intact after slicing.
