What happens if you eat Mac and Cheese that has been sitting out for too long? From a technical standpoint, nothing would change. If you’ve checked the ingredients and found no evidence of mold, lumps, or an unpleasant odor, you can proceed with using it. So, nothing bad will happen if you eat the expired mac and cheese that still looks, smells, and tastes good.

Does boxed Velveeta mac and cheese go bad?
