Preheat oven to 450°. Mix all ingredients in a large bowl and stir until combined.
Grease a 9 x 13 baking dish. Roll mixture into golf-ball-size meatballs, packing them firmly (wet hands to prevent meat from sticking; alternatively, you can use an ice cream scoop). Place meatballs in baking dish in even rows so they're touching.
Bake until meatballs are cooked through, about 14 minutes. Let rest 5 minutes, then serve.
