Preheat the oven: Set to 400Β°F (200Β°C). Line a baking sheet with parchment paper.
Cook the beef: Heat olive oil in a skillet over medium-high.
Add onion and cook 2 minutes. Stir in garlic for 30 seconds. Add ground beef, salt, pepper, smoked paprika, and Worcestershire.
Cook, breaking up, until browned and no pink remains, 5β7 minutes. Drain excess fat.
Add mix-ins: Off heat, stir in pickles and half of the cheese. Let the filling cool for 3β4 minutes so itβs easier to handle.
Prep the dough: Separate biscuit dough into 12 pieces.
If using pizza dough, divide into 12 equal balls and flatten into 3β4 inch rounds.
Fill and seal: Place about 1β2 tablespoons of beef mixture in the center of each round. Top with a pinch of the remaining cheese (or a cheese cube). Pull dough edges up and pinch to seal tightly.
Place seam-side down on the baking sheet.
Make the garlic-Parmesan butter: Stir together melted butter, Parmesan, and garlic powder. Brush the tops of the bombs. Sprinkle with sesame seeds if using.
Bake: Bake 12β15 minutes, until puffed and deep golden.
Brush lightly with any remaining butter mixture and finish with parsley.
Serve hot: Let rest 3 minutes, then plate with dipping sauces. Enjoy while melty and warm.
