When the foil comes off, the rolls are soft and steamy, and the Swiss has melted into the layers of ham. A few minutes uncovered gives the tops their golden finish without drying out the filling. That contrast is what makes these Ham and Cheese Sliders feel like more than little sandwiches.
I like how the sweetness of the Hawaiian rolls meets the salty ham and mellow Swiss. The Dijon and Worcestershire in the buttery topping add a savory edge, while poppy seeds bring a little crunch. They’re easy to portion for a casual meal or a snack table, and the 9×13-inch dish keeps all 12 together as they bake. Each slider comes out tender in the middle, with a buttery top and a warm, cheesy center.

Kitchen Note
Whisk the topping until the mustard and Worcestershire are blended through the melted butter, then brush it over the whole surface. I pay special attention to the outer rolls, which are easy to miss when the tray is full.
Save these Ham and Cheese Sliders for a gathering or an easy meal: sweet Hawaiian rolls, melted Swiss, and a savory Dijon-butter topping.
Why Keeping the Rolls Joined Makes These Sliders Easier to Handle
Cutting the rolls as one slab gives you a broad, level surface for the filling. The ham and cheese sit between two connected layers rather than inside 12 separate little sandwiches, so the filling is less likely to shift while you spread the mayonnaise or move the top half back into place. The joined rolls also bake together in the dish, which helps the finished sliders stay in a neat grid.
That approach is especially helpful with soft Hawaiian rolls. Pulling them apart before assembling leaves more edges exposed, and it’s harder to spread the mayonnaise evenly across individual pieces. Keep the loaf intact while you slice it horizontally, and use a long serrated knife with a gentle sawing motion rather than pressing down. If the top half tears slightly, set it back over the filling as evenly as you can; it will still bake into a single slab. Once baked, the roll seams give you natural lines for portioning.
What the Hawaiian Rolls, Swiss, and Topping Bring to the Tray

- Hawaiian rolls — Their slight sweetness balances the savory filling, and the connected package makes assembly straightforward. A soft pack of dinner rolls can stand in if needed, though the sliders will lose some of that sweet-and-salty contrast. Choose a fresh, soft package; dry rolls won’t give you the same tender center.
- Deli ham — Thin slices layer easily without making the sandwiches bulky. A good-quality deli ham gives the filling a cleaner, meatier taste, but a standard thin-sliced package works well here. Deli turkey is the most direct swap; it makes the sliders milder while keeping the same easy-to-layer texture.
- Swiss cheese — Swiss brings a mild, nutty flavor that doesn’t overpower the ham. Sliced cheese is convenient because it makes an even layer; provolone is a useful substitute when Swiss isn’t available, with a softer, less nutty flavor.
- Mayonnaise — Spread over the cut side of the bottom rolls, it adds richness between the bread and filling. Use a smooth mayonnaise that spreads easily; there’s no need for a specialty brand. Don’t skip spreading it over the full surface, since bare patches make for a less even bite.
- Butter and the savory seasonings — Melted unsalted butter carries the Dijon, Worcestershire, poppy seeds, and onion powder across the tops. Dijon contributes a sharper mustard note than yellow mustard, which can replace it for a gentler, more familiar tang. Unsalted butter lets the savory ingredients stay in balance; salted butter also works, though the topping will taste a little saltier.
How to Assemble and Bake the Sliders Without Drying the Tops
Slice the Slab and Prepare the Dish
Heat the oven to 350°F and coat a 9×13-inch baking dish with cooking spray. Keep the rolls together and slice the whole slab horizontally, aiming for an even top and bottom. Set the bottom half cut side up in the dish. A level cut makes it easier to spread the mayonnaise without tearing the soft bread.
Layer the Ham and Swiss Evenly
Spread mayonnaise over the cut side of the bottom half, reaching close to the edges. Layer the thinly sliced ham over it, then arrange the Swiss cheese across the ham. Even coverage matters more than making a tall stack: thick piles can make the center harder to portion neatly. Place the top half back over the filling and line up the edges.
Whisk the Buttery Topping
Melt the butter in a small bowl, then whisk in the Dijon mustard, Worcestershire sauce, poppy seeds, and onion powder. Keep whisking until the seasonings are distributed through the butter rather than sitting in separate streaks. Brush the mixture over the top of the rolls. If it pools in one spot, spread it out so the surface bakes evenly.
Let the Cheese Melt Before Browning the Tops
Cover the dish with foil and bake for 15 minutes. The covered bake warms the filling while shielding the tops from direct oven heat. Remove the foil and bake for another 5 to 8 minutes, until the rolls are golden and the cheese has melted. Rest the sliders for 5 minutes before serving so the hot filling settles into the rolls.
Three Simple Ways to Adapt These Ham and Cheese Sliders
Use Deli Turkey for a Milder Filling
Replace the ham with the same amount of thinly sliced deli turkey and keep the Swiss and topping unchanged. The flavor will be gentler, while the thin slices still fit neatly between the rolls.
Make a Dairy-Free Tray
Use dairy-free Hawaiian-style rolls, vegan mayonnaise, dairy-free Swiss-style slices, and plant-based butter. The sliders keep their sweet roll-and-savory filling contrast, though the cheese may melt differently and the topping won’t taste quite as buttery. Choose products that meet your own dietary needs.
Leave the Poppy Seeds Out
Omit the poppy seeds from the butter topping and keep the other topping ingredients as they are. You’ll still get the Dijon-onion seasoning and glossy baked tops, just without the little bit of crunch.
Storage and Reheating
- Refrigerator: Refrigerate leftovers within 2 hours and keep them in an airtight container for 3 to 4 days. The rolls soften as they sit.
- Freezer: Once cooled, wrap portions tightly and freeze in a freezer-safe bag for up to 2 months for the best texture. Thaw overnight in the refrigerator before reheating.
- Reheating: Cover with foil and warm in a 325°F oven until the center reaches 165°F, uncovering for the last few minutes if you want to crisp the tops. The microwave is quicker, but it can leave the bread soft and chewy.
