How to Store an Avocado, So You Don’t End Up With Brown Mush

So, you bought an avocado to make guacamole or a sandwich or ice cream. But, where's the best place to keep it? And what happens if you have half leftover? Today, we're going back to the basics on how to store an avocado—from when to keep at room temp to how to tell if it's ripe. Let's get started. 

Where is the best place to store an avocado?

Trick question: It depends on whether the avocado is ripe (see more on that below). Unripe avocados should be kept at room temperature, where they will gradually soften. Ripe avocados should be eaten immediately, or moved to the fridge where the chilly temperature will extend their shelf life by several days.

How do I know if an avocado is ripe?

Give it a (soft! gentle!) squeeze. The area around the stem should slightly give, like a bouncy stress ball. It should not feel puffy or mushy—that means it's gone too far. Check in every day to determine whether you should eat or transfer it to the fridge. 

I want toast now. Can I speed up the ripening process at all? 

A little. We advise buying firm avocados from the supermarket to increase your odds of avoiding brown mush. (The walk/bike/drive home can be trecherous for this fragile fruit.) That said, if you need an avocado ASAP, you can encourage its ripening by bundling in a brown bag for a couple days (add in a banana for good luck). 

What if I want to save half an avocado for later? 

A common conundrum. The most common piece of advice is to leave the pit in the avocado half, or rather, use the pitted half first. However, while the parts of flesh that are in contact with the pit stay fresh, the rest of the avocado easily browns. This is simply because the pit is blocking air from reaching part of the flesh. So, to keep the exposed avocado from browning, we have to mimic what the pit does and create alternative barriers. Though avocado halves will always brown to some degree, the following methods kept the fruit green, longer.

The Onion Method
Roughly chop a quarter of a red onion into large chunks. Line the bottom of a sealable container with the onion pieces, then place the avocado half cut side-up on top. Seal the container and keep in the fridge. According to The Kitchn, this is likely due to the vapors that onions emit. Luckily, because the skin is the only part of the avocado in contact with the onion, the flesh won't take on any flavor. And you can save the onions for later use!

The Olive Oil Method
Brush the avocado half with olive oil (pick one without a strong flavor). The oil will keep the flesh from coming in direct contact with the air, preventing oxidization. After brushing with the oil, store the avocado in an airtight container in the fridge. 

The Lemon Juice Method
You can also brush your avocado's flesh with lemon juice—the citric acid in the lemon juice dramatically slows the browning process. Again, store in an airtight container for extra protection.

Can you freeze avocados? 

Food52er Sarah Jampel tried her luck—freezing both avocado halves and avocado mash—and wouldn't recommend it. While the browning was certainly stalled, the texture was completely compromised. "The avocados were simultensouly mushy, slimy, and spongy," she writes. "Sure, you can 'save' an avocado in the freezer for later. But I'd argue that you're condemming it to a certain doom." Noted!

Should I put bananas on my avocado toast?

My lazy way works better than plastic wrap or lemon juice. I almost always have half an onion or a bunch of scallions in a bag in the fridge. I just throw the avocado half with a pit in the same bag. Recently I forgot about one in the fridge while I was away for a week. Found it and it was delicious. The top doesn't stay completely green but darkens a little bit after more than 3 days but still completely edible.

Well I can verify that everything said here is quite true, there is a very real danger in overeating avocados! My uncle was an avocado farmer we all love the fruit but because he was on the go so much while he was at the ranch tending his crops he would eat half a dozen or so because he really didn't have time for a full meal when he wasn't at the ranch he would still consume two or three a day after about 10 years of this he developed arterial sclerosis although the fat in avocados is great for you and overabundance is bad for your arteries. So don't get carried away!
Well then after he cut avocados out of his diet entirely following his massive surgeries to repair his arteries within about 4 years he developed cancer and soon died! Your friend in food, Captain John

The BEST BY FAR WAY TO KEEP AVOCADOs GREEN (not brown) is to Vacuum Pack them. I vacuum packed a sliced avocado a week ago and it still looks green as the day it was cut open!! You should update your article and add this solution!

I was just going to post the same comment!

Never do I worry about left over avocados. I always buy 2 for salads. When I peel and slice one putting it in a dish with lemon juice and course fresh ground pepper while I fix a salad I start by taking a nibble of a slice, then 2 slices, then I eat all the slices and have to peel the 2nd avocado for the salad. With just 2 of us one avocado is barely enough and never do we have any left over. Can anybody tell me how to grow the pit for a house plant??

Please can you tell me how I can buy one of the products listed in Food52.
The product I am interested in is a set of silicone lids (I think there were four or five in the set). I live in Australia, but I could not get my country to come up in the list for mailing.

Put a half of an avocado in a baggie and fill it with water put in the fridge. It last beautifully. Quick & simple.

I have found that Saran Wrap pressed firmly onto the surface of a cut avocado does great in letting it last longer in the refrigerator. I also do this when I make guacamole. When doing that, don't just cover the bowl the guacamole is in, you have to press the wrap right down on the guac.

I store my avocados in a paper bag and place the bag in the fridge. Avocados will still be good over a week later.

I cringed when I read to gently squeeze the avocado. (I know, you said "gently," but still...) My pet peeve is finding brown finger print spots inside beautiful avocados that I have just purchased. For this reason I always buy hard, unripe avocados and let them ripen at home because they are the least likely ones to have been damaged by overzealous shoppers. So if you want to squeeze avocados, please do so AFTER you've purchased them.

I don’t buy the whole fruit. I do buy the small snack sized trays and packets of guac. I freeze them thaw them out as needed . I didn’t detect any decline of quality in the thawed out product. The processed fruit is freezable . Just my two cents.

Thank you, thank you, thank you for the advice on where to feel the avocado to tell if it is ripe! I've been passing this tip along forever often to much skepticism. I grew up eating avocados from my grandfather's trees and was taught at an early age when to pick them how to store them and how to tell when they are ripe.
I always buy them rock hard. My counter is never without at least 2 avocados and my fridge likewise. Did I mention we eat a lot of avocados?
Our favorite salad is sliced avocados, white grapefruit segments on a bed of butter lettuce or other soft lettuce, drizzled with Dijon mustard tarragon vinaigrette and sprinkled with chopped green onions. Yum!

Don't cover it. Just put it in the fridge, it will form it's own protective skin. Also cut it around the middle holding it up.

What does this mean?
Christine H. February 14, 2021
Holding what up?
mdelgatty February 14, 2021
Maybe cut it around the middle when it's standing on end, rather that lying flat? The would at least decrease the area exposed to air...

I'm glad to have come across this tip! Was just talking to friends on how to keep them green longer. I will try some of these out to find out which one will work the best for me and maybe you too!

The working assumption of this piece is wrong: not only do I consume the entire avocado in one meal, it *IS* the meal. Along with a sliced plum tomato, on occasion, just for variety.

Usually I eat the half of the avocado and keep the skin of the other half. Covered it back and put it into the fridge, you can also use the cling wrap to wrap it up.
marlene July 7, 2015
a thick smear of butter works well and then wrap in cling wrap.
Natalie S. July 6, 2015
i just use plastic wrap, but have it loose enough to make sure the wrap is touching the exposed skin. keeps for days.
Pam C. July 6, 2015
If you don't have a vacuum sealer just put the avocado half in a zip lock bag and seal the bag with a straw end inside and suck the excess air out then seal the bag. It will keep it from browning for at least a few days.

"Leftover guacamole"?

Could happen, I suppose.
Julie W. July 6, 2015
Instead of lengthwise cut it in half crosswise - there is way less average Avocado exposed . I also put the leftover avocado in a container with half an onion , no need to cut it up - this keeps for a really long time
