Quick Answer

Layer sliced Kirkland Black Forest ham and Swiss between split King's Hawaiian rolls (kept connected as a slab), brush with a poppy-seed-Dijon-butter glaze, and bake at 350°F for 15 minutes covered, 5 minutes uncovered. Ready in 25 minutes; six servings of crowd-pleaser.

Ham and cheese sliders on King's Hawaiian rolls are the recipe everyone makes once for a party and then keeps making forever. Costco sells both the rolls and a great quality deli ham that fit this recipe perfectly. The garlic butter glaze soaks into the top of the rolls as they bake and creates a glossy, savory crust that makes the whole pan irresistible. They're equally good as a weeknight dinner or game day appetizer.

Instructions

  1. 1

    Preheat oven to 350°F.

  2. 2

    Without separating the rolls, slice the entire sheet horizontally in half. Place the bottom half in a greased 9x13 baking dish.

  3. 3

    Layer ham evenly over the bottom rolls. Lay Swiss cheese slices over the ham. Replace the top half of the rolls.

  4. 4

    Mix melted butter, Dijon, garlic powder, Worcestershire, and dried onion. Brush generously over the tops and sides of the rolls. Let any excess drip down into the pan.

  5. 5

    Sprinkle poppy seeds over the top if using. Cover tightly with foil.

  6. 6

    Bake covered for 10 minutes. Uncover and bake 5 more minutes until the tops are golden and the cheese is melted.

  7. 7

    Pull apart and serve immediately. They cool down fast and are best eaten right out of the oven.

Frequently Asked Questions

Can I assemble ham and cheese sliders ahead of time?+
Yes — assemble everything including the butter glaze, cover tightly with foil, and refrigerate for up to 12 hours. Bake from the fridge as directed, adding 5 minutes to the covered bake time since they're going in cold.
What cheese works best for sliders?+
Swiss is the classic choice — it melts well and complements the ham without overpowering the sweet roll. Provolone is an excellent substitute. Avoid pre-shredded cheese, which doesn't melt as smoothly as sliced.
Can I use a different meat?+
Turkey and cheddar is a popular variation. Pulled pork with pepper jack is excellent. Whatever you use, keep the ratio the same — about 1 oz of meat per roll.
Why are King's Hawaiian rolls ideal for sliders?+
Their soft, slightly sweet texture and connected sheet format are perfect for sliders — they don't fall apart under the meat and cheese, and slicing the whole sheet at once saves significant prep time. The sweetness of the roll balances the saltiness of the ham.
