Preheat oven: Set to 375°F (190°C). Line a baking sheet or pan with foil or parchment paper. Prepare the beef: In a bowl
mix ground beef with ranch seasoning
garlic powder
pepper
and salt. Press evenly into a 9×13-inch pan to form a flat layer. Bake the beef: Bake for 15–18 minutes
until fully cooked. Drain any excess grease. Use a spatula to loosen the beef from the pan and cut into 12 even squares. Assemble the sliders: Slice the connected slider buns horizontally. Place the bottom halves on a baking tray. Layer with the cooked beef squares
cheese slices
and bacon pieces. Add the top buns: Place the top half of the rolls over the sliders. Brush melted butter mixed with garlic powder over the tops. Sprinkle with chopped parsley if desired. Bake again: Cover loosely with foil and bake for 5–7 minutes
or until cheese melts. Uncover and bake for 2 more minutes to toast the tops. Serve: Cut into individual sliders and serve hot with extra ranch dressing for dipping.
