HOW DO YOU STORE COLCANNON? Allow it to cool all the way down, then put it in a sealed container with a tight-fitting lid. It will last 3-4 days in the refrigerator and tastes great leftover too! This makes it perfect for meal planning, as well. You can also keep the mashed colcannon in the freezer. Just cool it down, place it in a freezer-safe bag or container, and it will last up to 3 months. It’s a great idea to label any leftover food you freeze with the name and date, so you don’t forget how long it’s been in there.
