Lamb Forequarter Casserole. This casserole is so yummy! The trick is to cook it slowly for at least two and a half hours. It can also be done in the slow cooker. The lamb just falls off the bone when it is done correctly. Warning...if it is not cooked long enough the lamb will be tough! I always taste the sauce after an hour and a half to see if it needs anything added. I hope you enjoy this. By the way the recipe only allows me to put the chops as shoulders but I buy them labeled forequarters.
