In a large bowl combine the hamburger meat, egg, worcestershire sauce, bread crumbs, milk, minced onion, Italian seasoning, fresh basil, and parmesan cheese.
Using a spatula or your hands, mix all of the ingredients together well.
Shape the meat into balls that are about two inches around.
You can place the meatballs directly into the basket or you can line the basket with a little parchment paper and then place the meatballs on top. Place them in a single layer.
I was able to fit about 9 meatballs in at a time. You don’t want them to touch because you want them to cook evenly on all sides.
Cook them for about 6-8 minutes, turning them over once halfway through cooking time.
They’re ready when they’ve browned nicely on the outside and are cooked throughout!
Remove from heat. Allow to cool.
You can use the meatballs as is, topped with sauce, on top of pizza, pasta, or even as a meatball sub!
