Can you Freeze onions?

I have gotten lots of questions about freezer cooking, so I am slowly going to be posting my tips from week to week. Basically my favorite way of freezer cooking is to help out my time in the kitchen.

The easier it is to make my dinners, the less likely we are to head out to eat. The more we eat at home, the more money we save.

One of the easiest ways to start freezer cooking is to start with chopping onions.

Can you freeze chopped onions?

Chopping is our preferred method to freeze onions and it works great.

Chopping onions seems like such a simple task, but when you have to do it every day… It gets old! We eat a lot of onions, usually with every meal.

How to use Frozen Chopped Onions:

Frozen chopped onions are great for soups, stews and sautéing with vegetables. Even your crockpot meals, spaghetti, cooked dishes, and other easy meals just got easier. They are also great for caramelized onions.

You do not need to thaw. I personally prefer to freeze them in freezer bags. Just remove from freezer the amount you need and add to your recipes.

I know it seems so silly, but this is a HUGE time saver in the kitchen.

How to Freeze onions:

  • Peel and Chop Onion – Simply peel and chop your raw onions like you would for dinner. Check out How to Cut an Onion.
  • Chop Multiple Onions – Instead of chopping up one fresh onion, chop up 3 or 4 (it only takes a few minutes more). Plus, I only have to deal with the onion odor once.
Chopped onions placed in a storage container and in freezer bags.
  • Store Onion in freezer safe container – Then place in a freezer friendly container, or a baggy. I used to separate them into individual servings (like in the picture above), but now I just dump them all in one container or quart size zip lock freezer bag.
  • Place on a baking sheet – This is optional, but I like to take the freezer bags and lay them on a baking sheet. Then place in the freezer. This helps to freeze them flat and better for storage. Once frozen solid, then you can remove the baking sheet.
  • Freeze Onion – Onions freeze individually so it works out just as well to put them all in the same bag.
  • Take out what you need – When you need some you can just pull out the ones you need. This also works great with sliced onions, if you want to have sliced on hand for chicken fajitas.
  • Break apart Onions – Then just bang the frozen onions bag against the counter. The onions will break apart and just toss whatever you need in your pan or crockpot.

Freezing onions will save you money:

Onions are not the most expensive, but if you buy 10 onions or a bag of onions when they are at rock bottom price at Aldi or at our local store, Crest Market, you can then freeze them.

You can almost always find these cheap at any number of grocery stores.

Instead of paying FULL price for onions, you can now stock up at the lowest price possible. Plus you will also save more time in the kitchen when making soup stew and other delicious recipes.

How long do onions last in the freezer?

Onions last for awhile in the freezer, usually several several months. You can easily chop and freeze a large quantity and use them over time.

Now that you know how long can you freeze onions, it is so easy.  It is a great way to save time and money.

How to freeze onions and peppers:

You can freeze bell peppers just like you freeze onions. I save even more time and use a small food chopper or food processor to quickly and easily chop the veggies.

If you do not have one of these, I highly recommend them. They are such a time saver and you can get the veggies really fine.

I usually just chop the entire vegetable and freeze what I don’t need. It’s so nice to be able to just take the diced onion out of the freezer for recipes.

This is how I meal prep. It’s so quick and easy and helps get dinner on the table fast.

Can you freeze green onions?

Yes! You absolutely can freeze green onions.

Simply chop and freeze the green onion the same as you would a regular onion. Easy!

We love green onions and it saves a lot of time having them in the freezer.

Can you freeze chopped celery?

You can freeze celery and it is another great time saver. It is best to use frozen celery for cooking because it will lose its crispness after freezing.

  1. Potatoes CAN be frozen generally if they are cooked first. I do not recommend adding any dairy products prior to freezing because the milk particles will separate from the water and the appearance and texture will not be as good. However, adding this things while re-heating, or even better, after re-heating is preferable. For most vegetables like onions, celery, peppers of ALL kinds, carrots, etc, just dice or chop them as you normally would and then place them in a single layer on a baking sheet and place in the freezer for 20 to 30 minutes. Remove them from the freezer and use a nylon spatula to free the frozen veggies from the baking sheet, placing them in a Ziploc bag. When the bag is full, press the air out and seal it. Place it in the freezer immediately. They will remain totally separated (no banging necessary) and you can scoop out the required amount and return the remaining frozen onions, celery, etc. to the freezer right away to keep them from partially thawing. You can also freeze prepped whole bell peppers (for stuffing) after removing the top, seeds and veins (be sure to chop the tops after removing the stems and freeze them separately). Wrap them in a single layer of plastic wrap and store them in the freezer for later use. Frozen prepped whole bell peppers also make great freezer containers for almost any kind of leftovers. Just remove one or more (as necessary) from the freezer, unwrap the plastic wrap and fill the pepper with your leftovers (spaghetti, mashed potatoes, any kind of casserole, etc.) and then re-wrap with the same plastic wrap. When you want a quick single-serving meal, remove it from the freezer, unwrap it and place it in the microwave for 6 to 7 minutes depending on the power of your microwave oven. It will come out (and I was surprised by this too) tasting just like you had just made it (the contents) fresh and just now removed it from the stove, crock pot, pressure cooker, etc..

  2. Freezing onions does save time, but the problem I have is my whole freezer smells like onions no matter how well I package them. maybe someone has an idea to help prevent that.

  3. My mom taught me how to freeze onions and green peppers when I was little. It saves time and tears haha. I also feeeze green and red peppers. This year, I grew celery and froze that also -it was my first time for both. I slice peppers and onions into strips for burritos and fajitas too. Thank you for sharing!

  4. You can freeze potatoes. I like to peel some and cut into chunks for soup or just cut some up leaving the skins on. You must balance them, then I lay them on a cookie sheet, put a piece of wax paper or something over them, put in freezer then put in freezer bags. Sounds like a lot of steps but it preserves my potatoes and they are ready when I am.

  5. Thanks for sharing Diane. I always have trouble with potatoes turning brown when I freeze them but I will definitely try it out this wqy!

  6. Thank you for all the ideas l’m getting busy and follow as many as I can. Question: how about zucchini and yellow squash?

  7. I do not think that these freeze well as they become very mushy once they have defrosted.

  8. I usually only use the onions that have been frozen to cook with as the onions do get pretty soft when they defrost out from being frozen.
