Can I safely freeze my yogurt marinated chicken?
I have been in this situation before and I did try freezing it. When I used it later on, it did taste and feel OK, but as you would expect, not the real fresh taste.

I do not think the ingredients in the marinade will have any effect while it is frozen. While thawing, the yogurt might split, leaving more than usual water, but that shouldnt alter much of the outcome. It will be still good after defrosting; I would normally defrost by leaving the item in the refrigerator overnight, rather than quick methods like microwaving or even leaving at room temperature on the kitchen counter.
