❄️How To Store Green Bean Casserole So It Stays Fresh
Let it cool completely: Never store hot food in the fridge as it can cause the temperature to rise and potentially spoil other food. Let your green bean casserole sit out until it reaches room temperature before storing.
Cover it up: You want to make sure your green bean casserole is covered tightly so it doesn’t dry out or form a crust on top. Use plastic wrap, aluminum foil, or a lid that fits snugly so it keeps its flavors.
Label and date it: This will help you keep track of how long the casserole has been stored and how long it will last in the fridge.
Store it in the refrigerator: Once your green bean casserole is properly covered and labeled, place it in the fridge where it will stay fresh for up to four days.
How to freeze green bean casserole: To freeze a green bean casserole, let it cool completely after baking, then cover it tightly with a layer of plastic wrap followed by a layer of aluminum foil. This can be stored in the freezer for up to 3 months; thaw it in the refrigerator overnight and reheat in the oven before serving.
