Preheat oven to 350°F (175°C) and grease a 9x13-inch baking dish.

Without separating the rolls, slice the entire pack of rolls in half horizontally, creating a top and bottom layer.
03 -
Place the bottom half of the rolls in the prepared baking dish. Layer the ham slices evenly over the bottom half of the rolls, followed by the Swiss cheese. Top with the remaining half of the rolls to form sliders.
04 -
In a small bowl, whisk together melted butter, Dijon mustard (if using), brown sugar, Worcestershire sauce, onion powder, garlic powder, and a pinch of salt and pepper.
05 -
Pour the butter sauce evenly over the top of the assembled sliders. Use a brush or spoon to spread it out. Sprinkle poppy seeds over the top, if desired.
06 -
Cover the baking dish with foil and bake in the preheated oven for 15 minutes. After 15 minutes, remove the foil and bake for an additional 5-7 minutes, or until the tops of the sliders are golden brown and crispy.

Let the sliders cool for a couple of minutes before slicing and serving. Enjoy these warm, cheesy, and savory sliders!
