How Long Does Mac And Cheese Last In The Fridge
Macaroni and cheese can be stored in the fridge for up to four days. However, after two days the flavor will start to fade. If mac and cheese are kept in an airtight container in a freezer, they will last longer. You can reheat the mac and cheese in the microwave.
Cooked macaroni lasts for approximately 1 to 2 months in the freezer when stored correctly in a sealed container, plastic freezer bag, or a heavy-duty freezing container. While fresh homemade mac and cheese lasts just days, shelf-stable packaged products such as Velveeta or Kraft macaroni and cheese keep for years if not opened and stored in a cool, dry location. Mac and cheese purchased at a grocery store in boxed, pre-packaged products like Kraft mac and cheese has an extremely long shelf life, which can last years without going bad. The actual shelf life of canned macaroni and cheese may be between one to two years, provided that it is stored correctly.
Properly storing your mac and cheese in a freezer will extend its shelf life significantly due to the cooler freezer temperatures which stop bacterial growth on your mac and cheese. If you are unsure whether or not you can consume the entire amount of the mac and cheese within 3-5 days, freezing it will make it hold up for longer. Freezing macaroni and cheese is feasible, but you need to do so with precision so it lasts the longest in your freezer. It must be eaten while still hot, then, if it has any leftovers, it should be stored in the refrigerator.

Before you heat it, let a freezer-safe container sit in the refrigerator overnight to give it a chance to fully thaw.
Place into a freezer-safe sealable bag or an airtight container, and keep frozen for 3 or 4 months. In addition to heating, be sure to top your baked casserole with fresh cheese before heating in the oven. Then, you can pack the chewy mac & cheese into a freezer-safe bag or container and keep it in the refrigerator up to 6 months. When you bake the macaroni in a box, that time may drop from several hours at room temperature to just a few days in the refrigerator.

Frozen cooked mac & cheese thawed in the fridge may last there 3-4 days before being heated, but a thawed macaroni in a microwave oven or a water bath needs to be heated immediately and consumed. You should never store cooked hot mac and cheese directly in an air-tight container inside the bag, or moisture built up inside the container due to steam released by hot mac and cheese will create an appropriate environment for bacteria and germs to grow inside.
