How long can cooked macaroni last without a fridge?

Cooked macaroni should not be left out at room temperature for more than 2 hours, according to the USDA. This is because macaroni is a moist food that is susceptible to bacterial growth. When cooked macaroni is left out at room temperature, bacteria can multiply rapidly and cause the macaroni to become unsafe to eat. Symptoms of food poisoning from macaroni can include nausea, vomiting, diarrhea, and abdominal pain.

To prevent food poisoning, it is important to refrigerate cooked macaroni within 2 hours of cooking. Cooked macaroni can be stored in the refrigerator for up to 3-5 days. If you are not going to eat the cooked macaroni within 3-5 days, it is best to freeze it. Cooked macaroni can be frozen for up to 2-3 months.

When you are ready to eat the cooked macaroni, be sure to reheat it thoroughly until it reaches an internal temperature of 165 degrees Fahrenheit. This will kill any bacteria that may have grown on the macaroni.
