Why You Must Make

  • These sliders got my husband to actually eat and enjoy corned beef!
  • They’re perfect for game day snacking and tailgates.
  • They have all the elements of a Reuben sandwich in a mini version.
  • You can make these with your St. Patrick’s Day leftovers.

Yes, my half-Irish husband does not like corned beef. His mom would make him a steak every St. Patrick’s Day when she served her traditional corned beef and cabbage meal. Imagine my surprise when he grew interested in these corned beef sliders as they were cooking in the oven!

Reader Endorsement:

 I had made corned beef a day before so I figured I could make some sliders. I found your recipe, quite by chance, and I couldn’t have been happier! My husband thought they were the tastiest item at the tailgate. My daughter-in-law, who is a very picky eater, ate her entire sandwich.

The sandwich has a beautiful balance of sweet and tangy. The buttery topping makes for a very rich flavor. I will definitely make these again.

Expert Tips

  • You can definitely use your leftover St. Patrick’s Day corned beef for this recipe. Just slice it very thin. I used deli corned beef which makes it super easy.
  • Homemade Russian dressing is simple to whisk together. But if you’re short on time, look for a decent brand of store-bought Russian salad dressing to use instead.
  • I lined my baking dish with parchment paper for easy cleanup. This is totally optional.
  • There are a couple of other optional steps, including sprinkling the tops with grated Parmesan and a quick stint under the broiler to brown the tops. If you elect to broil, do not walk away or your buns could easily burn.

Frequently Asked Questions

Yield 6

Corned Beef Sliders with gooey Swiss cheese, deli corned beef, homemade Russian dressing and sauerkraut even got rave reviews from the man who had declared his dislike of corned beef for decades!


Homemade Russian Dressing:

  • ⅓ cup mayonnaise
  • 1 ½ tablespoons ketchup
  • 1 ½ teaspoons horseradish
  • ½ teaspoon Worcestershire sauce
  • Salt and pepper, to taste


  • 1 package slider buns (12 count)
  • ½ pound sliced corned beef, freshly cut deli version preferred
  • 1 cup sauerkraut, drained
  • 12 slices Swiss cheese (about 8 ounces)


  • ¼ cup (½ stick) butter, melted
  • 1 tablespoon Dijon mustard
  • ½ teaspoon garlic powder
  • 1 tablespoon parmesan cheese
  • 2 teaspoons poppy seeds
  • Parmesan, to sprinkle over sandwiches, if desired


  1. Preheat the oven to 350º.
  2. Make homemade Russian dressing by whisking together mayonnaise, ketchup, horseradish, Worcestershire, and salt and pepper to taste. Set aside.
  3. Cut slider buns in half horizontally. Place the bottom buns in an oven-safe dish (I did not separate them).
  4. Spread dressing on buns. Layer with half the corned beef, half the cheese, the sauerkraut, the rest of the corned beef, and the rest of the cheese.  Add the top buns.
  5. Make the butter topping by mixing all the ingredients together. Drizzle over buns. May sprinkle with more Parmesan if desired.
  6. Cover the buns with foil and bake for 30 minutes or until the cheese is melted and sandwiches are heated through.
  7. Remove foil and broil for just a minute if desired.
  8. Cut into individual sliders and serve warm.


Deli corned beef works best as it's cut nice and thin. But if you'd like to use leftover corned beef, just slice it as thin as possible.
