How to make life easier with one simple recipe? Whip up a huge chicken casserole, then freeze half (or the whole pot) to enjoy another day. Love creamy casseroles? You’re going to love this one, flavoured with white wine, mustard, crème fraîche and dijon mustard. For something slightly different, take a look at this chicken casserole with tarragon dumplings or these chicken supremes with a wild mushroom and tarragon sauce.
