How To Store / Freeze This Dish
Allow the green bean casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the casserole to an airtight container. If you don't have a container large enough, you can cover the baking dish tightly with plastic wrap or aluminum foil.
Store the casserole in the refrigerator for up to 3-4 days. For best results, reheat in the oven at 350°F (175°C) until warmed through, about 20-25 minutes.
To freeze, first ensure the casserole is completely cooled. Then, transfer it to a freezer-safe container or wrap it tightly with plastic wrap followed by aluminum foil to prevent freezer burn.
Label the container with the date so you can keep track of its freshness. The casserole can be frozen for up to 2-3 months.
When ready to enjoy, thaw the casserole in the refrigerator overnight. Reheat in the oven at 350°F (175°C) for about 30-35 minutes, or until heated through. If the fried onions on top become too dark, cover the dish loosely with foil during reheating.
For individual portions, consider freezing the casserole in smaller containers. This makes it easier to reheat just the amount you need, reducing waste and ensuring each serving is as fresh as possible.
If you find the casserole a bit dry after reheating, you can add a splash of milk or cream of mushroom soup to restore its creamy texture.
