Cooked instant noodles typically have a limited shelf life without refrigeration due to the risk of bacterial growth and food spoilage. If left at room temperature, cooked instant noodles can become unsafe to eat within 2 hours. After 2 hours, bacteria can multiply rapidly, especially in a warm environment, leading to potential foodborne illnesses.
To extend the shelf life of cooked instant noodles, it's best to refrigerate them promptly. When stored in an airtight container in the refrigerator, cooked instant noodles can last for about 3-5 days.
If you need to store cooked instant noodles for a more extended period, consider freezing them. Frozen cooked noodles can last for 1 to 2 months. However, freezing may affect the texture of the noodles, so be prepared for some softening once they are thawed and reheated.
Remember, always use your judgment when it comes to food safety. If you notice any signs of spoilage, such as an off odor, strange texture, or unusual appearance, it's best to discard the cooked instant noodles rather than risking foodborne illness.
