How to Freeze Onions

How to Freeze Onions
Whether you grow your own onions or  buy them in bulk, freezing onions is a great way to preserve them and shorten your meal prep time. 

Not to mention, how many times have you used part of an onion, sealed the the rest up and put it in the fridge, just to have to throw it away a few days later? I think we have all done that... several times.

Frozen onions are perfect for soups, casseroles, stir-fry and any other recipes that will consist of cooking the onions. 
Aside from preserving them and preventing waste, one of my main reasons for freezing onions is simply to save on prep time. If I'm going to cut up an onion, I usually go ahead and cut them all up and then freeze them, and be done with them. This saves on prep time later, plus I don't have to worry about stinky hands every time I need onions for a recipe. 

I have been asked several times, "how do I freeze onions?" and the answer is always simple...

How to Freeze Onions

What You Will Need:Cutting Board
Sharp Knife
Quart or Gallon Freezer Bags
Optional: Onion Slicer- If I am doing a big batch I break out my handy onion slicer and complete the task in no time. 

You can cut and freeze one onion at the time or cut a whole bag full {this is where the onion slicer comes in handy}. Just use what ever you have and add to it as needed.

First peel your onions as you normally would.

Next, wash the onions with cool water and pat dry.

Using a slicer, or a sharp knife and a cutting board, slice or dice your onions to your own preference. I usually slice them into rings and then, quarter the slices.  I typically don't dice them simply because leaving them in 1/4 slices will allow me to have bigger onions for stir-fry and pot roast. If I need them diced, I simply dice them before tossing them in my recipe. 
If you are looking for a good onion slicer these are a few of the highly rated slicers that are on the rather inexpensive side of the scale. The reviews are great!

After cutting the onions to your preference, put them in a gallon or quart freezer bag. 

Can you freeze onions?
Make sure you get all the air out of the
bag to keep them fresher, longer! 
This is the important part: After bagging the onions, remove the air. Of course, you won't be able to remove all the air but, do your best. Now seal and toss them in the freezer! They will easily last 2-3 months with no problem. 

Now, next time you need onions for your favorite recipe, simply reach in, take out what you need and toss them in your recipe. Tah-da! Quick and easy- no prep, no mess and no stinky hands! 

I also do this with my bell peppers to cut down on prep time. If I am making stir-fry or another recipe that requires bell peppers and onions, I will usually cut a couple extra of each one and then freeze them together. Next time I make stir-fry, I simply pull the bag of mixed peppers and onions out, pop them in the skillet! Super quick and super easy!

    1. You can also freeze bell peppers the same way! Makes it so easy for making meals that would typically require extended prep time. Plus, it helps prevent waste on those nights you don't need a whole onion or pepper. :)

  2. I froze bell peppers, but I never froze onions. I didn't even know you could freeze onions. Now that I know, it will save me a lot for not having to replace onions that have gone bad in the refrigerator.

    Thanks so much for sharing on Turn It Up Tuesday! We love having you! :)
