Prepare the oven and pan. Preheat the oven to 375°F and line a large rimmed baking sheet with foil. Place a cooling rack in the pan.
Make the meatball mixture. 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 meatballs. Shape the meat mixture into uniform 1-inch meatballs and arrange them on the rack.
Bake. Bake the meatballs 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.
