They can be frozen cooked or raw and kept well for up to 2 months. Prepare the meatballs according to your recipe. Allow the cooked meatballs to cool completely, then place them in a single layer on a baking sheet. Transfer frozen and cooked meatballs to freezer bags or freezer-safe containers and label them with the type of meatball and the date.
Cooked and frozen meatballs can be defrosted overnight in the refrigerator or reheated directly from the freezer. Reheat meatballs cooked in a sauce on the stove or in a hot oven, but don't turn up the heat too high. You don't want the outside of the meatball to cook too much before the inside has time to heat up. Transfer the meatballs to a freezer bag or freezer-safe container, label with the type of meatball and the date, and freeze them for 1 to 2 months.
