Expiration & Storage Tips
When does polenta expire?
Unopened polenta packages can last up to 1 year past the printed expiration date when stored in a cool, dry place. Once opened, dry polenta should be stored in an airtight container and will last up to 6 months. However, cooked polenta has a significantly shorter shelf life and should be consumed within 4-5 days if refrigerated. When frozen, cooked polenta can last up to 2 months.
How do you tell if polenta is bad?
Spoiled dry polenta will typically adopt a dull appearance and may have molds or a musty odor. If you notice any such abnormalities, it's best to dispose of it. Cooked polenta will also emit a sour or off-putting odor if gone bad, and could have a slimy texture or even show visible mold. Discard it at the first sign of these symptoms.
Tips for storing polenta to extend shelf life
• Store dry polenta in an airtight container in a cool, dark place (like a pantry) to keep it fresh longer.
• Refrigerate cooked polenta within two hours of cooking in shallow, covered containers to ensure it cools down quickly and properly to prevent bacterial growth.
• Freeze cooked polenta in individual portions for easy use in the future. Just ensure it's cooled completely before going into the freezer. To avoid freezer burn and maintain quality, wrap tightly in plastic wrap and then again in foil.
• To defrost, transfer the frozen polenta to the refrigerator the night before. You can then reheat on the stovetop or in the microwave, adding a little water or milk to refresh its creamy texture if needed.
