Baked Corned Beef Sliders are the ultimate way to transform leftover St. Patrick’s Day corned beef (or a deli purchase) into a warm, melty, buttery, crowd-pleasing meal in minutes. This recipe is a celebration of simplicity and flavor, layering tender, salty corned beef and nutty Swiss cheese between soft, sweet Hawaiian rolls, then baking everything to golden, toasty perfection. The magic begins with a sheet of slider buns kept intact, sliced horizontally to create a top and bottom “lid.” Generous layers of corned beef and Swiss cheese are stacked between, creating a cohesive, sandwich-like slab that’s easy to assemble and slice. A generous brushing of melted butter over the tops ensures the buns turn gloriously golden and crisp in the oven, while the covered bake guarantees the cheese melts into a gooey, irresistible layer.
The brilliance of this recipe lies in its simplicity and the incredible result it delivers with almost no effort. The sliders bake together as one connected sheet, then are sliced into individual portions, making them perfect for parties, game-day spreads, or a quick family dinner. The combination of salty corned beef and buttery Swiss is a classic for a reason, and the sweet Hawaiian rolls provide the perfect soft, slightly sweet counterpoint. For an extra layer of flavor, add a swipe of Russian dressing, Thousand Island, or spicy brown mustard before layering the meat. Serve these sliders warm, straight from the oven, and watch them disappear.

Ingredients:
For the Sliders:*
12 small slider buns or one sheet (12-count) Hawaiian rolls, kept together
12 ounces thinly sliced corned beef (deli or leftover)
6 slices Swiss cheese, cut in half (or 12 small pieces)
For the Topping:*
4 tablespoons (½ stick) unsalted butter, melted
Optional Add-Ons:*
Russian dressing, Thousand Island dressing, or spicy brown mustard
Instructions:
Step 1: Preheat Oven and Prepare Dish*
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Step 2: Prepare the Rolls*
Without separating the individual rolls, slice the entire sheet of slider buns horizontally in half using a serrated knife. Place the bottom half of the rolls (cut-side up) in the prepared baking dish.
Step 3: Layer the Filling*
If using dressing, spread a thin layer over the bottom buns. Evenly distribute the sliced corned beef over the bottom buns, covering the entire surface. Arrange the Swiss cheese pieces evenly over the corned beef.
Step 4: Add the Tops*
Place the top half of the rolls back over the layered filling, pressing down gently.
Step 5: Butter the Rolls*
Brush the melted butter evenly over the tops of the buns, making sure to coat the edges.
Step 6: Bake Covered*
Cover the baking dish loosely with aluminum foil. Bake for 12-15 minutes, until the cheese is melted and the sliders are heated through.
Step 7: Finish and Serve*
Remove the foil and bake for an additional 2-3 minutes to lightly toast the tops. Remove from the oven and let cool for 2 minutes. Using a sharp knife, slice along the roll lines to separate into individual sliders. Serve warm.
Tips:
- Keep Rolls Attached: Keeping the buns connected makes assembly and slicing much easier.
- Use a Serrated Knife: A serrated knife slices through the soft rolls cleanly without squishing them.
- Don’t Skip the Foil: Covering the sliders for the first part of baking ensures the cheese melts fully without burning the tops.
- Add Sauerkraut: For a Reuben slider, add a layer of well-drained sauerkraut over the corned beef before adding the cheese.
- Customize the Cheese: Provolone, provolone, or cheddar work beautifully in place of Swiss.
Storage Options:
- Refrigerator: Store leftover sliders in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in a 350°F (175°C) oven or air fryer for 5-7 minutes to restore crispness. The microwave will make the buns soft.
- Make-Ahead: Assemble the sliders (without baking) up to 24 hours in advance. Cover and refrigerate. Add the butter topping just before baking.
Baked Corned Beef Sliders are a warm, buttery, cheesy, and satisfying way to enjoy the classic deli combination. Perfect for parties, leftovers, or a quick dinner, they’re guaranteed to be a hit.
