Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
In a skillet over medium heat, add the ground beef, diced onion, and minced garlic. Cook until the beef is browned, about 5-7 minutes. Drain excess fat if necessary.
Stir in Worcestershire sauce, salt, and pepper. Remove from heat and let cool for a few minutes.
Mix the shredded cheddar cheese into the beef mixture until well combined.
Unroll the crescent roll dough and separate it into triangles as per the package instructions.
Place about 1-2 tablespoons of the cheeseburger filling at the wide end of each crescent roll triangle. Roll up tightly and place seam-side down on the prepared baking sheet.
In a bowl, mix the melted butter with a little garlic powder (optional) for extra flavor. Brush the garlic butter over the tops of each roll-up.
Bake in the preheated oven for 15-20 minutes or until the rolls are golden brown.
Once baked, remove from the oven and let cool slightly. Garnish with chopped fresh parsley when serving.
