Notes
Easy Meatballs
While the classic presentation is to serve this meatball recipe on a bed of freshly cooked spaghetti, you can also serve Italian meatballs on a bed of steamed veggies, accompanied by white or brown rice or as the filling of a hearty meatball sandwich.
For evenly-sized meatballs that will cook in the same amount of time, pat the meat mixture into a 6x4-inch square. Cut into 24 squares. Roll each square into a ball.
Mix things up by substituting 1 pound lean ground turkey or chicken for the ground beef. (If using ground chicken, decrease milk to 2 tablespoons.) Bake until no longer pink in center and thermometer inserted in center reads 165°F.
