Step 1

Preheat oven to 400ºF. Spray a large cookie sheet with cooking spray.

In a small saucepan cook the onions until they are soft and tender. Let them cool.

Step 3

Mix together onion, bread crumbs, garlic, egg, cheese, salt, pepper and parsley in a large mixing bowl.

Step 4

Add in ground beef and mix gently until combined. Do not overwork. Form into 1-inch balls and place on prepared cookie sheet.

Step 5

Bake in preheated oven for 15-20 minutes, or until meatballs are browned and cooked through.

Step 6

While the meatballs are baking in the oven, cook your spaghetti noodles according to the package directions.

Step 7

In a large bowl, combine your meatballs, noodles, sauce, and parmesan cheese. Mix everything together and add that to an 8X11 pan. Top with the part-skim mozzarella cheese and bake the casserole in an oven for 15 to 20 minutes.
