Preheat your oven to 400°F (200°C).
In a large skillet, cook the ground beef over medium heat until browned, about 5-7 minutes, breaking it apart with a spatula.
Add minced garlic, onion powder, salt, and black pepper to the cooked beef, and stir for an additional minute until fragrant.
Remove the skillet from heat and stir in the cheddar and Parmesan cheeses until melted and well combined.
Open the can of biscuit dough and separate the dough into rounds or squares, depending on the style you prefer.
Place a spoonful of the beef and cheese mixture in the center of each dough piece.
Cup the dough around the filling and pinch to seal the edges, forming a ball. Ensure it’s tightly sealed to prevent leakage during baking.
Arrange the sealed bombs on a baking sheet lined with parchment paper.
Brush the tops with melted butter and sprinkle with additional Parmesan cheese.
Bake in the preheated oven for 15-20 minutes until golden brown and bubbling.
Remove from the oven and let cool for a few minutes before serving. Garnish with chopped parsley.
