Drain any excess milk from the breadcrumbs and add them to the meat mixture.

Add the egg to the meat mixture.

Pour the olive oil onto your hands and gently mix the meat using your hands until the breadcrumbs, spices, and egg are evenly distributed. Avoid overmixing.

Gently roll each meatball and place them on the lined baking sheet, leaving about 2 inches between each meatball.

Bake meatballs for 18-20 minutes, flipping them after 12 minutes to ensure even browning.
