Yes, cook them first! I always freeze meatballs. Freeze them first on a cookie sheet in the freezer, uncovered, then toss them into a zip lock bag and take the air out with a straw.
Ditto cooking first and wrapping tightly -but also make sure they're 100% cooled before you wrap them up. Otherwise condensation forms on the inside of the Saran Wrap and turns into water when you reheat them upon use.
Freezing them cooked is much easier. I toss them in a freezer bag, but if you aren't going to use them for a few months, you may want to wrap them tightly in saran. I wouldn't take the time to wrap them individually, but would wrap saran around them all together, then put that in a freezer bag, get as much air out as possible and then seal the bag.
I made a very large batch of turkey-bison meatballs. I want to freeze half of them to defrost after I give birth in late May. I am not sure if I should freeze them pre-cooked or go ahead and cook then freeze? They have fresh onion, garlic, basil and parsley in them too if that makes a difference. Thanks for any words of wisdom.
Oh, also could use some help on how to package them for freezer. just plain freezer bag?
