Preheat the oven to 350°F. Lightly grease a 9x13-inch baking dish or line it with parchment for easier lifting.

Add the pulled pork and barbecue sauce to a skillet over medium heat. Cook for 4-5 minutes, stirring often, until hot, glossy, and thick enough to mound on a spoon.

Slice the attached rolls in half horizontally without separating them. Place the bottom slab in the prepared baking dish.
04 -
Spread the warm pork evenly over the rolls. Add pickles and red onion, then layer on the smoked Gouda and cheddar. Set the top slab of rolls over the filling.
05 -
Stir together the melted butter, Worcestershire sauce, garlic powder, smoked paprika, parsley, and salt. Brush the mixture over the tops of the rolls.

Cover the dish loosely with foil and bake for 12 minutes, until the cheese begins to melt and the center is hot.
07 -
Remove the foil and bake for 6-8 minutes longer, until the tops are golden and the cheese is fully melted.

Let the sliders rest for 5 minutes, then cut along the roll lines. Serve warm with extra barbecue sauce on the side.
