These ham and cheese sliders are baked until warm, melty, and golden, making them an easy crowd-pleasing meal or party snack. A savory butter glaze with Dijon, Worcestershire, and poppy seeds adds extra flavor to every bite.
Preheat the oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish.
Without separating the rolls, slice the whole batch of rolls in half horizontally and place the bottom halves in the prepared baking dish.
Layer the ham evenly over the bottom halves, then top with the Swiss cheese slices. Place the top halves of the rolls over the cheese.
In a small bowl, whisk together the melted butter, Dijon mustard, Worcestershire sauce, poppy seeds, onion powder, garlic powder, and black pepper.
Pour the butter mixture evenly over the tops of the sliders, making sure to coat all of the rolls.
Cover the dish with foil and bake for 15 minutes.
Remove the foil and bake for 5 to 10 minutes more, until the tops are golden and the cheese is melted.
Let the sliders cool for a few minutes before serving warm.
Notes
You can substitute provolone or cheddar for the Swiss cheese if desired. For extra flavor, brush a little more butter mixture over the tops right after baking.
