After cooking hot dogs, they can stay good in the refrigerator for about 3 to 4 days. It is important to promptly store the cooked hot dogs in an airtight container or wrap them tightly in plastic wrap or aluminum foil before placing them in the refrigerator. This helps prevent the hot dogs from absorbing odors and also minimizes the risk of bacterial growth.
If you plan to store hot dogs for an extended period, it's better to freeze them. Cooked hot dogs can last for 1 to 2 months when properly stored in the freezer.
Always use your best judgment and follow proper food safety guidelines when handling cooked food. If the hot dogs develop an off smell, unusual texture, or show signs of spoilage, it's best to discard them to avoid any potential health risks.
