Ingredients

For the Topping

Butter — the base of the poppy seed topping that gets brushed over the finished sliders. Salted or unsalted both work
Dijon mustard — adds a subtle tangy depth to the topping that balances the sweetness of the Hawaiian rolls perfectly
Worcestershire sauce — adds savory umami depth to the topping. A small amount makes a big difference
Brown sugar — a small amount that enhances the caramelized flavor of the topping without making it overly sweet
Poppy seeds — the classic finishing touch that gives these sliders their signature look and a subtle nutty flavor
Dried minced onion — adds savory depth to the topping without any chopping required

For the Sliders

Butter — melted on the griddle for toasting the rolls to a golden brown bottom
King’s Hawaiian rolls — the sweet soft rolls that make these sliders so iconic. Keep them connected when slicing for easier assembly. Any soft slider roll works as a substitute
Thinly sliced deli ham — the classic filling. Turkey, roast beef, or chicken all work as substitutes
Swiss cheese — melts beautifully and pairs perfectly with ham. Provolone, cheddar, or Colby Jack all work as substitutes

Carrie’s Tip: Watch the Hawaiian rolls closely while toasting — their natural sweetness makes them brown significantly faster than regular rolls. Keep the heat on low and check them every 30 seconds so they get golden without burning.

How to Make Blackstone Ham and Cheese Sliders

Step 1 – Preheat the Blackstone grill with two heat zones: one set to medium-low heat and the other set to low heat.

Combining the buttery topping ingredients in the saucepan

Step 2 – In a small saucepan, combine butter, Dijon mustard, Worcestershire sauce, brown sugar, poppy seeds, and dried minced onion. Place the saucepan on the medium-low heat zone and stir until the butter is completely melted and the ingredients are combined. Remove from heat.

Slicing the Hawaiian Rolls in half with a knife.

Step 3 – Slice 12 King’s Hawaiian rolls in half horizontally, keeping the rolls connected if possible. Set the tops aside.

Step 4 – Melt 1 tablespoon butter on the low heat zone of the Blackstone grill. Place the bottom half of the rolls cut side down on the griddle and toast lightly until golden brown.

Deli ham placed on the Blackstone Griddle.

Step 5 – Place thinly sliced deli ham on the griddle next to the rolls, arranging it into sections about the same size as the rolls.

Slice cheese placed on the deli ham on the griddle.

Step 6 – Top the ham with 8 ounces thinly sliced Swiss cheese and cook for 1–2 minutes, or until the cheese is melted.

Brushing the buttery topping on the cooked sliders on the griddle.

Step 7 – Remove the toasted bottom rolls from the griddle and carefully place the ham and melted cheese on top. Add the top half of the rolls. Brush the prepared butter topping evenly over the tops of the rolls.

Step 8 – Separate into individual sliders and serve warm. Enjoy!

Tips for Success

Use two heat zones. The low zone for the rolls prevents burning while the medium-low zone heats the topping sauce — running everything at the same temperature makes it hard to control
Keep the rolls connected. Slicing and assembling while the rolls are still connected makes building the sliders significantly faster and easier — separate into individual sliders right before serving
Use a melting dome or foil tent. Covering the ham and cheese briefly on the griddle traps heat and melts the cheese in about half the time — a game changer for a crowd
Watch the rolls closely. Hawaiian rolls have more sugar than regular rolls and brown very quickly. Check every 30 seconds and pull them the moment they are lightly golden
Brush the topping generously. Do not be shy with the butter topping! A generous coat over every roll is what makes these taste like the classic party sliders everyone knows and loves
Wrap in foil to keep warm. If serving at a party wrap the assembled sliders in foil to keep them warm for up to 30 minutes. Perfect for cookouts and game day spreads

Variations and Substitutions

Swap deli ham for turkey, roast beef, or pulled chicken for a different flavor profile
Use provolone, cheddar, or Colby Jack instead of Swiss for a different cheese flavor
Add a thin layer of Dijon mustard directly on the roll bottoms before assembling for extra tang
Add sliced pickles or banana peppers inside for a bolder flavor
Make a Reuben version — swap the ham for corned beef and add sauerkraut and Thousand Island dressing

Storage and Freezer Instructions

Refrigerator

Store assembled sliders wrapped in foil or in an airtight container for up to 3 days

Freezer

Freeze assembled sliders before brushing with the topping. Wrap tightly in foil and freeze for up to 3 months. Add the butter topping after reheating for the freshest result

Reheating

Reheat wrapped in foil in a 325°F oven for 10–15 minutes — avoid the microwave as it makes the rolls soft and soggy

Frequently Asked Questions

Can I make these sliders without a Blackstone?

Yes — toast the rolls in a skillet over medium-low heat and melt the ham and cheese in the same skillet or oven at 350°F for 10 minutes.

How do I keep ham and cheese sliders warm for a party?

Wrap assembled sliders tightly in foil and keep in a 200°F oven or wrap in foil on the low heat zone of the Blackstone for up to 30 minutes before serving.

What cheese works best for ham and cheese sliders?

Swiss is the classic choice and melts beautifully with ham — provolone, cheddar, and Colby Jack all work great as substitutes.

Can I make these ahead of time?

Yes — assemble the sliders up to 24 hours ahead, refrigerate without the topping, and brush with the butter topping right before heating on the Blackstone.

Why are my Hawaiian rolls burning?

The heat is too high — always toast Hawaiian rolls on the lowest heat setting and check every 30 seconds since their natural sweetness causes them to brown much faster than regular rolls.
