If you are not ready to do meal prep yet and want to preserve the oatmeal for long, then you can try this method.


  • Dry Oatmeal


  • Freezer-Safe Air-Tight Container or Ziploc Bags


    1. Portion: If you would like to portion the oatmeal beforehand, you can do it before packing them. But since it is a dry ingredient, you could pack it as a whole and scoop out the portion you need and seal the rest.

    2. Pack and Seal: Transfer the dry oats into a freezer-safe container or Ziploc bag and seal them. Make sure that the Ziploc bag or container is as air-tight as it can be. You can use a straw to suck the excess air out of the Ziploc bag before sealing them.

    3. Label and Freeze: Add a label with the date on the container or bag, and you are good to go.

Flash Freeze

leave the muffin tray in the freezer for a couple of hours or overnight and let it freeze solid.

Freezing Oatmeal in Freezer-Safe Container

Time Taken: 5 minutes 

What you will need: 

  • Oatmeal 
  • Freezer-Safe Container or Ziploc Bag 

This method is best used when you have some leftovers and want to freeze small quantities.

Cool Down

If the oatmeal has just been cooked, let it cool down to room temperature.

Portion and Pack

If there is excess and you are not sure if you can consume it all in one go, portion it out into single-servings. Then pack them into a freezer-safe container or Ziploc bag.

Seal Them

If you are using a freezer-safe container, make sure to leave an inch space at the top to make room for the oatmeal to expand when it freezes. Then seal the container.

If you are using a Ziploc bag, try to squeeze out all the excess air and use a straw to make the process easier.

Label and Freeze

Add a label with the best-before date, and you are all set to freeze the oatmeal.

How Long Can You Freeze Oatmeal? 

You can freeze oatmeal for up to 6 months without any change in its taste or quality. You could even add dried fruits and nuts to the mix when you prepare them to freeze. 

But it is best to consume it as soon as you can rather than leaving it in the freezer for long and eventually forgetting about it. 

With that being said, it is a great meal prep idea, and you can freeze oatmeal for breakfast that can last you for a few weeks. 

How to Store Frozen Oatmeal? 

You can store oatmeal in any freezer-safe air-tight container or Ziploc bag. You could also freeze them in mason jars if you are sure they are freezer-safe and won’t crack once frozen. 

If you are running out of space in the freezer, the best option would be to store the oatmeal in a Ziploc bag. 

Especially if you are freezing oatmeal in a muffin tray, they can be quite bulky, and it might not be easy to cram too many into a container.

So instead of wasting precious freezer space with bulky containers, you could opt for Ziploc bags. 

How to Defrost Oatmeal? 

You can defrost oatmeal by leaving the portion you need in the fridge for a couple of hours or overnight and letting it thaw gradually. 

You could also pop it in the microwave, heat it quickly, or heat it on a pan if you are in a hurry. But keep in mind that if the oatmeal has been defrosted in the microwave or on the kitchen counter, it must be consumed immediately. 

If it had been defrosted slowly in the fridge, you can use it up within a day or two, provided it is kept in the fridge when not in use. 

Can You Refreeze Oatmeal? 

No, it is best advised not to refreeze oatmeal. Once it thaws, the frozen oatmeal can go through changes in texture which will only worsen with repeated freezing.

Especially if you have added fruits and nuts, it would be best to consume them right away once defrosted. 

To avoid wasting oatmeal once it thaws, portion them beforehand into easy-to-manage servings. 

Does Oatmeal Freeze Well? 

Yes, oatmeal freezes well and is a great way to do some meal prep and preserve oats simultaneously.

You can use the same methods mentioned above for all different kinds of oats and oatmeal recipes. They can last well in the freezer for up to 6 months with little to no change in their quality. 

Dry oats can also freeze well and last in the freezer for a whole year or so. The key to freezing it is making sure that the container is air-tight. 


Can you freeze oatmeal made with milk? 

Yes, you can freeze oatmeal made with milk. Though it can last for long in the freezer, it would be safe to consume it within 3 months. They cannot be refrozen and must be consumed immediately once they thaw. 

Can you freeze oatmeal for baby food? 

Yes, you can freeze oatmeal for baby food, and they can last long in the freezer. But it is best advised to consume them as soon as you can. Make sure to double bag and keep it in an air-tight container to avoid any freezer burns.
