These easy party-sized sandwich sliders are the perfect appetizer for game days, holidays, potlucks, showers, and casual family gatherings. Made with 24 Hawaiian-style sweet rolls, thinly sliced deli ham, Swiss cheese, and a savory buttery Dijon topping, they bake in one dish and are ready in about 35–40 minutes.
The rolls stay connected while you assemble and bake them, which keeps preparation quick and helps every slider stay warm and moist. The finished sandwiches have sweet, tender bread, salty ham, creamy melted cheese, and a fragrant topping of Worcestershire sauce, poppy seeds, dried onion, garlic powder, and Dijon mustard.

When you need an appetizer that feeds a crowd without requiring individual sandwich assembly, these baked sliders are an excellent choice. All 24 sandwiches fit into one baking dish, and the rolls can be cut, filled, topped, and baked as a single connected batch.
The flavor is satisfying without being complicated. Sweet Hawaiian rolls balance the savory ham, nutty Swiss cheese, tangy Dijon, and rich butter sauce, while poppy seeds and dried onion add the familiar party-sandwich finish.
These sliders also make a flexible centerpiece for an appetizer table. Serve them alongside easy air fryer meatballs for another warm, hearty bite, or add a bright dip such as hot pepper jelly for guests who enjoy sweet heat.
Ingredients You’ll Need
The ingredient list is short, but each item contributes to the finished texture and flavor. Begin with two 12-count packages of Hawaiian-style sweet dinner rolls, keeping the packages intact until they are sliced horizontally.
- Rolls: Hawaiian-style sweet rolls provide a soft, lightly sweet base and a golden top.
- Ham: One pound of thinly sliced deli ham gives the sliders a generous, even filling.
- Swiss cheese: Use 12 slices, halved, or about 12 ounces of shredded Swiss so the cheese covers the ham well.
- Butter sauce: Melted unsalted butter carries the Dijon, Worcestershire sauce, poppy seeds, dried onion, garlic powder, and salt across the tops of the sandwiches.
If you prefer a less sweet appetizer, use soft dinner rolls instead of Hawaiian rolls. For a different flavor profile, turkey, roast beef, or a combination of deli meats can replace the ham.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F and lightly grease a 9-by-13-inch baking dish. Greasing the dish helps prevent the bottom rolls from sticking and makes serving easier after baking.
Step 2: Without separating the rolls individually, slice each package horizontally to create a connected top section and bottom section. Use a long serrated knife and a gentle sawing motion so the bread stays intact rather than tearing.
Step 3: Place both connected bottom sections in the prepared baking dish. If needed, arrange them snugly side by side so the entire base is covered before adding the filling.
Step 4: Layer the thinly sliced ham evenly over the rolls, folding larger slices as needed to fit the corners. Cover the ham with the halved Swiss slices or an even layer of shredded cheese, making sure the filling reaches close to the edges.
Step 5: Place the connected tops of the rolls over the cheese. In a small bowl, whisk the melted butter, Dijon mustard, Worcestershire sauce, poppy seeds, dried minced onion, garlic powder, and salt until combined.
Step 6: Pour or brush the butter mixture evenly over the tops of the rolls. Let the assembled sliders stand for about 5 minutes, giving the sauce time to soak into the bread and season the tops.
Step 7: Cover the baking dish tightly with foil and bake for 12–15 minutes. Keeping the sliders covered for most of the cooking time allows the cheese to melt and the sandwiches to heat without browning the tops too quickly.
Step 8: Remove the foil and return the dish to the oven for another 3–5 minutes. Bake until the roll tops are lightly browned, then use a knife to separate the sliders and serve them warm.
Pro Tips for Perfect Sliders
The most important technique is to keep the rolls connected while slicing, filling, and baking. This not only saves time but also helps the bread retain moisture and prevents individual rolls from shifting around in the dish.
Spread the ham and cheese as evenly as possible. An even filling means every guest gets the same satisfying combination of meat, melted cheese, and soft bread.
Covering the pan with foil is also essential. The covered baking period warms the center and melts the Swiss, while the short uncovered finish gives the tops a lightly toasted appearance without making them dry.
For a make-ahead option, assemble the sandwiches several hours before serving, cover the dish, and refrigerate it. Add roughly 5 minutes to the covered baking time when cooking the chilled sliders, then uncover and brown the tops as directed.
If you are building a larger appetizer spread, these sliders pair nicely with a tropical main-style bite such as this grilled Hawaiian chicken sandwich. For another easy handheld option, consider adding pizza sliders to the menu.
Easy Variations and Serving Ideas
Swiss cheese is traditional for this combination, but the recipe welcomes substitutions. Provolone creates a mild, creamy result, cheddar adds a sharper flavor, and pepper Jack brings gentle heat.
For the meat, replace the ham with thinly sliced turkey, roast beef, or a combination of deli meats. Keep the amount close to one pound so the sandwiches remain generously filled without becoming difficult to cut and serve.
Serve the sliders straight from the baking dish on a platter or wooden board. They are especially appealing when the tops are still warm and glossy, with the melted cheese visible between the connected rolls.
For a complete party table, arrange the sliders with fresh vegetable sticks, pickles, chips, fruit, and a small bowl of dipping sauce. A sweet-and-spicy condiment such as hot pepper jelly can provide a lively contrast to the buttery sandwiches.
Storage and Reheating
These sliders are best served warm, but leftovers can be covered and refrigerated. Store them in the baking dish or an airtight container and reheat until warmed through.
When preparing the recipe ahead, refrigeration is most useful before baking. Keep the assembled and covered dish chilled, then bake it from cold with roughly 5 additional minutes added to the covered portion of the baking time.
Try to separate only the number of sliders you plan to serve. Keeping the remaining sandwiches connected helps them retain moisture and makes reheating more consistent.
Frequently Asked Questions
Can I use shredded Swiss cheese? Yes. About 12 ounces of shredded Swiss works in place of 12 halved cheese slices; distribute it evenly over the ham so it melts throughout the pan.
Why should I not separate the rolls before baking? Connected rolls are faster to assemble and easier to keep moist. The intact sections also help the fillings stay aligned as the cheese melts.
Can I make these less sweet? Yes. Replace the Hawaiian-style rolls with soft dinner rolls for a less sweet sandwich while keeping the same ham, cheese, and butter topping method.
How do I stop the tops from browning too early? Cover the dish with foil for the first 12–15 minutes. Remove the foil only for the final 3–5 minutes, when the cheese should already be melted and the sandwiches hot.
