Make these easy Italian Grinder Sliders, baked on soft Hawaiian rolls with deli meats, provolone, and a savory garlic butter glaze. They are perfect party appetizers and a crowd-pleasing choice for game day or quick weeknight dinners.
Preheat your oven to 350 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
Slice the entire package of slider rolls horizontally, keeping the rolls connected in one piece. Place the bottom half of the rolls in the prepared baking dish.
Layer the deli meats evenly over the bottom half of the rolls: ham, turkey, and salami.
Place the provolone and Swiss cheese slices over the meats, covering the entire surface.
Place the top half of the rolls over the cheese layer.
In a small bowl, whisk together the melted butter, mayonnaise, Dijon mustard, Italian seasoning, garlic powder, onion powder, and oregano to create the glaze.
Pour the butter glaze evenly over the top of the assembled sliders.
Cover the baking dish tightly with aluminum foil.
Bake for 15 minutes.
Remove the foil and bake for another 5 to 10 minutes, or until the cheese is fully melted and the tops of the rolls are golden brown.
Carefully slice the sliders apart between the rolls. Serve warm immediately.
Notes
For extra flavor, you can add a thin layer of pepperoncini peppers or banana peppers over the cheese before adding the top roll.
If you do not have Hawaiian rolls, use any soft, small slider bun.
You can assemble these grinder sliders up to four hours ahead of time and keep them covered in the refrigerator before baking. Add 5-10 minutes to the covered baking time if baking straight from the fridge.
