The best ham and cheese sliders on Hawaiian rolls with a buttery Dijon glaze! Sweet King's Hawaiian rolls, layered with honey ham and melty Swiss cheese, topped with a buttery poppy seed glaze, then baked until golden. Ready in 30 minutes, make-ahead friendly, and the first thing to disappear at any party.
Whisk together 5 tbsp melted butter, 1 tbsp Dijon mustard, 1/2 tbsp poppy seeds, 1/2 tbsp dried minced onion, and 2 tsp Worcestershire sauce in a bowl. Set aside.
Without separating the rolls, use a serrated knife to slice the entire bag of King's Hawaiian rolls horizontally through the center to make one large top and one large bottom slab.
Place the bottom slab in a 9x13 baking pan.
Layer 1/4 lb ham, then 1/4 lb Swiss cheese, then the remaining 1/4 lb ham, then the remaining 1/4 lb Swiss cheese on top.
Place the top slab of rolls back on.
Pour the entire butter glaze evenly over the top of the rolls.
Cover with foil and bake at 350°F for 15 minutes. Remove the foil and bake for 5 more minutes until the tops are golden and the cheese is melted.
Cut along the roll lines into individual sliders and serve warm!
Notes
Make-ahead: Assemble sliders (ham and cheese only) up to 24 hours ahead. Cover and refrigerate. Add the glaze right before baking.Prevent soggy bottoms: Lightly toast the bottom halves of the buns at 350 degrees F for 3 to 5 minutes before layering. Or wait to add the glaze until just before baking.Keep warm: Place the covered baking dish in a 200°F oven for up to 30 minutes.Air fryer reheat: 325°F for 3-4 minutes. Best way to reheat leftovers!Freeze: Assemble unbaked sliders, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge. Add glaze and bake as directed.Serving: 2 to 3 per person as an appetizer, 3 to 4 as a main. One batch (12 rolls) serves 6 to 8 as an appetizer.Variations: Try turkey and provolone, chicken and cheddar, or a garlic herb butter glaze instead of the Dijon glaze.
