- 8–10 slices Swiss cheese
- 4–6 slices provolone or mozzarella cheese, optional
- 2–3 tablespoons butter, for the bottom of the buns
- 2 tablespoons mayonnaise
- 1–2 tablespoons Dijon mustard
- 2–3 tablespoons sauerkraut, optional
- Pickles, optional
For the buttery topping
- 4 tablespoons melted butter

- ½ teaspoon onion powder
- 1 teaspoon dried parsley
- 1 tablespoon sesame seeds or poppy seeds, optional
- Small pinch of salt and black pepper
👩🍳 Instructions
1. Prepare the oven
Preheat your oven to 180°C / 350°F.
Line a baking tray with aluminum foil or parchment paper. This makes cleanup much easier and also helps keep the sliders together while baking.
2. Prepare the buns
Without separating the individual rolls, carefully slice the entire package of slider buns horizontally.
Place the bottom halves of the buns on the prepared baking sheet.
Spread a thin layer of butter over the bottom buns.
For extra flavor, mix the mayonnaise and Dijon mustard together and spread a little over the buns.
3. Add the corned beef
Pile the cooked corned beef generously over the bottom buns.
Don’t be afraid to make the layer thick. The corned beef is the star of these sandwiches!
If your corned beef is very thick, slice it thinly or shred it into smaller pieces so it distributes evenly.
4. Add the cheese
Cover the corned beef with Swiss cheese.
You can add provolone or mozzarella as well if you want the sandwiches especially cheesy.
For the best result, make sure the cheese covers most of the meat. As it melts, it will hold everything together.
5. Add optional toppings
If you enjoy a classic deli-style flavor, add a small amount of sauerkraut.
You can also add thinly sliced pickles or a little extra Dijon mustard.
Don’t add too much moisture, however, because you want the buns to remain pleasantly soft rather than soggy.
6. Add the top buns
Place the top halves of the buns over the cheese and corned beef.
Press gently so everything sits together.
🧈 Buttery Topping
In a small bowl, combine:
- Melted butter
- Dijon mustard
- Worcestershire sauce
- Garlic powder
- Onion powder
- Dried parsley
- Sesame or poppy seeds
Mix well.
Brush the buttery mixture generously over the tops of the buns.
This is one of the secrets to getting that beautiful golden, shiny, flavorful crust seen in the picture.
🔥 Baking Method
Cover the tray loosely with aluminum foil.
Bake for approximately 10 minutes.
Remove the foil and continue baking for another 5–8 minutes, until:
- The buns are golden brown.
- The cheese is completely melted.
- The corned beef is hot.
- The edges are slightly crisp.
For an extra-golden top, you can place the tray under the broiler for 1–2 minutes, watching carefully so the buns don’t burn.
Allow the sliders to rest for about 5 minutes before cutting them apart.
⭐ The Best Method for Extra-Cheesy Sliders
For the most delicious result, use this layering method:
Bun → Butter → Sauce → Corned Beef → Swiss Cheese → Optional Sauerkraut → Top Bun → Garlic Butter
The cheese melts around the corned beef and helps create that wonderful combination of crispy edges, juicy meat, and stretchy melted cheese.
🥩 About the Corned Beef
Corned beef is traditionally beef that has been cured in a seasoned salt brine. It became especially associated with Irish-American cuisine and is commonly enjoyed with cabbage, potatoes, mustard, rye bread, or sauerkraut.
Turning corned beef into small baked sliders is a modern, party-friendly way to enjoy those familiar flavors.
These sliders are particularly useful when you have leftover cooked corned beef because the meat can be reheated and transformed into an entirely different meal.

💡 Tips for Perfect Sliders
Use good-quality buns
Soft brioche or Hawaiian-style rolls work beautifully because they become lightly toasted on top while remaining soft inside.
Don’t skimp on cheese
A generous layer of Swiss cheese gives the sliders their signature creamy, melty texture.
Warm the corned beef
Cold meat straight from the refrigerator won’t heat as evenly. Warm it gently before assembling.
Don’t overload with sauce
Too much sauce can make the buns soggy. A thin layer is enough.
Bake covered first
Covering the sliders initially helps the cheese melt and keeps the bread from browning too quickly.
Finish uncovered
The final uncovered baking time gives the buns their beautiful golden crust.
🥪 Make-Ahead Method
You can assemble the sliders several hours before serving.
Prepare everything up to the point of adding the buttery topping. Cover and refrigerate.
When you’re ready to bake, brush with the butter mixture and place them in a preheated oven.
If they’re coming directly from the refrigerator, allow a few extra minutes of baking time.
🧊 Storage
Place leftover sliders in an airtight container and refrigerate for up to 3 days.
To reheat, place them in a 180°C / 350°F oven for about 8–10 minutes until hot.
An air fryer can also work well for reheating individual sliders.
❄️ Freezing
For best texture, these sliders are better enjoyed fresh, but they can be frozen.
Wrap individual sliders tightly in foil and place them in a freezer-safe bag.
Thaw overnight in the refrigerator, then reheat in the oven until warmed through.
