Yes, you can freeze them and defrost them before cooking them.
If the meatloaf is cooked and frozen just as soon as it is cooled down, Yes.If it is uncooked then, unless you know the meet it was made form was not frozen before, No.Meatloaf can be frozen - either cooked or uncooked.If you plan to freeze uncooked meatloaf, use the freshest ingredients, wrap it securely to prevent freezer burn and get it into the freezer ASAP. Regarding the Gather at the Table link that's attached . . . I would not recommend leaving the meatloaf to thaw on the counter or in the oven all day before cooking. It would be best to cook from frozen or to thaw overnight in the fridge.
yes, as long as it is cooled to room temperature before freezing.
Yes, but you will need to dry them REALLY well before cooking.
Yes, you can safely freeze onions. It's best to dice the onion before freezing and use them for cooking.
You can safely freeze dressing before or after it is cooked.
Once frozen, meat should not be refrozen without being cooked first. So if you have thawed 2 pounds of ground beef and then you bake a meatloaf with it, then you can re-freeze the meatloaf. But don't re-freeze the raw hamburger.
You can indeed.
Yes you can. From my experience it keeps well for up to six weeks.
If you are going to be cooking with them, yes.
Doesn't matter, its already cooked. If you aren't going to it it for a while you can freeze it to keep it fresh (as long as it is sealed) and take it out to reheat when ever you want to eat, repeating until its gone. I recommend slicing it before you freeze it for easy portions.
yes you can freeze cutlets after cooking ,but when you have serve it you must heat then serve.
