Expiration & Storage Tips
When does macaroni and cheese expire?
When it comes to prepackaged, unopened store-bought macaroni and cheese, it typically can last unopened in your pantry for up to a year past its 'best by' date. However, once you've prepared macaroni and cheese, whether it's from a box or homemade, it’s safe in the fridge for about 3 to 5 days. If you decide to freeze it, it can keep for up to 2 months.
How do you tell if macaroni and cheese is bad?
It's pretty easy to tell when macaroni and cheese has gone bad. If it has been in your refrigerator for more than 5 days or in your freezer for more than 2 months, it's safer to throw it away. Additionally, if the appearance of the macaroni and cheese has changed – if it has dried out or has visible mold growth - or if it emits a sour or off smell, it definitely needs to head to the trash.
Tips for storing macaroni and cheese to extend shelf life
• Always refrigerate leftover macaroni and cheese within two hours of cooking to reduce the risk of bacterial growth.
• Use airtight containers or heavy-duty freezer bags to store macaroni and cheese in the refrigerator or freezer.
• If freezing, consider dividing into meal-sized portions for convenient defrosting and reheating.
• When ready to eat frozen macaroni and cheese, allow it to thaw in the refrigerator overnight, then reheat in the oven or microwave until hot and bubbly.
