Although it may be drier in texture than when it was fresh, the way to tell if your mac and cheese has gone bad is by the appearance and smell. If the dish has an unpleasant, sour scent, or if it has visible mold around the outside, then the mac and cheese needs to go straight in the bin. Although you typically would not get seriously sick from this, it would be a very unpleasant experience and may leave you with a dodgy stomach. | Can you eat expired Mac and Cheese? | #macandcheese #comfortfood
