Leftovers are common with this recipe Green bean casserole serves a crowd! But can you freeze the leftovers to enjoy later?
The short answer is yes, you can absolutely freeze leftover green bean casserole. This method allows you to preserve the casserole for up to 6 months.
Freezing is an excellent way to save your leftover green bean casserole so you can enjoy it again without waste. In this article, I’ll explain the best practices for freezing green bean casserole step-by-step.
How Long Does Leftover Green Bean Casserole Last?
Before jumping into the freezing process, let’s first discuss how long leftover green bean casserole lasts in the fridge.
Properly stored in an airtight container, leftover green bean casserole will last 3-4 days in the refrigerator. Make sure to store it towards the back of the fridge, away from the door where temperatures fluctuate.
After 3-4 days, the quality and safety of the casserole will decline. At this point, you’ll need to throw it out or freeze it for longer term storage.
Freezing is the best way to preserve green bean casserole past the 3-4 day mark. Frozen properly, it can last in the freezer for 6 months.
Can You Freeze Green Bean Casserole With Onions?
When freezing green bean casserole, you have two options:
-
Freeze the entire casserole with onions mixed in and on top
-
Freeze just the green bean mixture, without onions
Either method works, but for best results I recommend freezing just the green bean mixture without onions.
The crunchy fried onions can get soggy in the freezer. Freezing just the green bean component keeps the texture intact.
Then, simply top with fresh crispy onions after thawing and reheating your casserole. This restores the contrast of creamy green beans and crunchy onions.
However, don’t worry if you’ve already mixed onions into your casserole. It can still be frozen successfully. The onions just may not retain their signature crunch.
Step-by-Step Guide to Freezing Green Bean Casserole
Follow these simple steps for freezing green bean casserole:
1. Let the casserole cool completely
- Allow the hot casserole to come to room temperature before freezing. Hot food will raise the temperature inside your freezer, shortening the shelf life of other frozen items.
2. Transfer to freezer bags or airtight containers
-
For the green bean mixture without onions, transfer it to ziplock freezer bags. Press out excess air before sealing.
-
You can also use rigid airtight containers like plastic Tupperware. Make sure to leave 1⁄2 inch of headspace to allow for expansion.
3. Seal tightly
- Remove as much air as possible and seal the bags or containers tightly. Air exposure causes freezer burn.
4. Label
- Label the containers with the contents and freeze date. This lets you keep track of how long it’s been frozen.
5. Freeze immediately
- Place the casserole bags or containers in the freezer right away. Don’t leave them out on the counter.
6. Freeze for up to 6 months
- For best quality and food safety, use your frozen green bean casserole within 6 months. Mark your calendar when it needs to be eaten by.
