To keep your chicken sausage fresh for as long as possible, make sure to store it in a sealed container at a consistent refrigerator temperature below 40°F (4°C). You can also freeze it for up to 2 months, which is a great option if you don't plan on using it within a few days.
Now, you might be thinking, "What about cooked chicken sausage?" Well, the good news is that it can last for around 5 to 7 days in the fridge, as long as it's stored properly. Just make sure to cool it down to room temperature before refrigerating or freezing it, to prevent bacterial growth.
