Line a large rimmed baking sheet with foil and place a cooling rack in the pan.
Whisk the egg in a large bowl. Add the ground beef, Parmesan cheese, basil, oregano, salt, pepper, garlic, and breadcrumbs. Mix until thoroughly blended.
Shape the meat mixture into 1-inch meatballs and arrange them on the rack.
Bake for about 20 minutes, or until the meatballs reach the minimum safe temperature of 160 F. If using ground turkey or chicken, bake to 165 F.
