01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, combine ground beef, onion, garlic, egg, breadcrumbs, Worcestershire sauce, smoked paprika, oregano, salt, and black pepper. Mix gently until just combined—do not overwork the meat mixture.
03 - Roll the mixture into small balls about 1 inch in diameter and place them on the prepared baking sheet, leaving space between each bite.
04 - Lightly brush the tops with olive oil to promote even browning during baking.
05 - Bake for 18-20 minutes, or until cooked through and golden brown. The internal temperature should reach 160°F.
06 - Let cool slightly on the baking sheet for 5 minutes. Serve warm or at room temperature with toothpicks and your choice of dipping sauce.
