Tips

  • How long does a package of macaroni and cheese mix last? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of macaroni and cheese mix store in a cool, dry area.
  • How long does macaroni and cheese mix last at room temperature? Properly stored, a package of macaroni and cheese mix will generally stay at best quality for about 2 years at room temperature.
  • To maximize the shelf life of macaroni and cheese mix, keep the package tightly closed at all times.
  • Is macaroni and cheese mix safe to use after the "expiration" date on the package? Yes, provided it is properly stored and the package is undamaged - commercially packaged macaroni and cheese mix will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the macaroni and cheese mix will remain at peak quality.
  • Storage time shown is for best quality only - after that, the macaroni and cheese mix's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly, the package is undamaged, and there are no signs of spoilage (see below).
  • How can you tell if macaroni and cheese mix is bad or spoiled? The best way is to smell and look at the macaroni and cheese mix: if the macaroni and cheese mix develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
