1 pound ground chuck beef
4 ounces Italian seasoned bread crumbs
4 ounces whole milk
6 ounces grated Pecorino-Romano
3 ounces grated onion
2 ounces minced garlic
1 tablespoon finely chopped Italian parsley leaves
1 tablespoon basil
Preheat oven to 350 degrees F. Grease a baking sheet with olive oil. Mix all ingredients thoroughly in large bowl. If mixture is too wet, add more bread crumbs.
Roll meatballs loosely about the size of a golf ball and place on baking sheet. Bake in the oven for approximately 35 minutes. Turn the meatballs over half way though.
