These gloriously soft Hawaiian rolls are split and loaded with layers of thinly sliced ham and gooey Swiss cheese, all baked together in a single pan until the tops are glossy and the cheese is a stringy, molten dream. The magic is in the sauce—a simple brush of melted butter, Dijon mustard, a whisper of poppy seeds, and a tiny pinch of onion powder that bakes into a golden, flavorful crust.
For best flavor, let assembled sliders sit in fridge for 30 minutes before baking. Can assemble night before and refrigerate; add 2-3 minutes to covered baking time if starting from cold. Don’t skip the 5-minute rest after baking to allow cheese to set. Watch closely during uncovered baking to prevent burning.
