These sliders feature thinly sliced corned beef stacked on buttery slider rolls, complemented by the tangy kick of stone ground mustard and melted Swiss cheese. Adding shredded cabbage or sauerkraut provides a subtle crunch and a balance of flavors. Brushed with a seasoned butter mixture and baked until golden, they make an ideal easy-to-make party snack or hearty bite. Optional garnishes like chopped chives or a spread of mayonnaise can personalize each slider, enhancing both texture and taste.

The first time I made these sliders, it was for a last-minute game day gathering when my cousin showed up with three unexpected friends. I had leftover corned beef from St. Patrick's Day and a pack of slider rolls that were about to go stale. Now they're the most requested item at every family gathering, and I've learned to always keep extra corned beef in the freezer just in case.

Last winter, my neighbor smelled these baking through our shared wall and knocked on the door with a container of her homemade pickles. We ended up eating the whole batch standing in my kitchen while the snow fell outside. Now every time she smells garlic butter, she assumes Im making sliders.

Ingredients

  • Cooked corned beef: Ask your deli counter to slice it paper thin, or shave it at home if you have access to a meat slicer
  • Slider rolls: Brioche adds sweetness but plain potato rolls work beautifully too
  • Swiss cheese: The nutty flavor balances the salty beef perfectly
  • Stone ground mustard: Those crunchy mustard seeds are what make each bite interesting
  • Shredded cabbage or sauerkraut: Adds a fresh crunch that cuts through the rich meat and cheese
  • Butter mixture: The poppy seeds add a subtle crunch while garlic powder gives it that familiar comfort food aroma

Instructions

Prep your station:
Preheat oven to 180°C and line a baking sheet with parchment paper for easy cleanup
Build the foundation:
Slice rolls in half and arrange bottom halves on your prepared baking sheet
Add the flavor base:
Spread stone ground mustard on each bottom half, adding a touch of mayonnaise if you like creamier sandwiches
Layer it up:
Pile on sliced corned beef, top with Swiss cheese, and add a spoonful of cabbage or sauerkraut
Close it up:
Place the top halves of the rolls over all those fillings
Make the magic topping:
Whisk together melted butter with poppy seeds and garlic powder
Brush and bake:
Cover with foil and bake for 10 minutes, then uncover for 3 to 5 minutes until tops are golden
Finish and serve:
Sprinkle with chives if you want a pop of color and serve immediately

My daughter helped me make these for her birthday sleepover, and all her friends asked for the recipe before they even left the house. Something about sliders makes people feel like kids again, reaching in and grabbing without thinking about silverware or plates.

Making Them Ahead

Ive learned through trial and error that you can assemble these sliders up to 24 hours in advance. Wrap the baking sheet tightly with plastic wrap and store in the refrigerator. Add the butter mixture right before baking, or the rolls will get soggy from the liquid.

The Reuben Variation

Replace the stone ground mustard with Russian dressing and swap cheddar for the Swiss cheese. Use rye slider rolls if you can find them. This version tastes exactly like the classic Reuben sandwich but in handheld form that's easier for parties.

Serving Suggestions

These sliders disappear faster than any other party food I make, so I always double the recipe for crowds. They pair perfectly with crispy potato chips and cold beer.

  • Cut them in half diagonally for easier grabbing at cocktail parties
  • Set out extra mustard on the side for guests who like it strong
  • Warm any leftovers in a 160°C oven for 5 minutes instead of the microwave

There's something about serving food that people can eat with their hands that makes gatherings feel more relaxed. These sliders have a way of pulling people toward the kitchen, drawn in by that buttery garlic scent.
