Cauliflowers were on sale and you’ve brought home one head too many. Now, you need to know how long does cauliflower last.
Or perhaps you’re not quite familiar with this veggie, and you need to learn how to store cauliflower heads, or how to tell if yours is still okay to eat or not.
Either way, this article is for you. In it, we’re going to cover:
- storing cauliflower at home
- freezing cauliflower – how and when to do it
- storage time of this veggie
- signs that you should throw out your cauliflower head
After reading this piece, you should be well equipped to handle your cauliflower “situation.” Read on.
How To Store Cauliflower
The best place to store cauliflower is the fridge (UMN).
Of course, you can get away with leaving it in the pantry for a couple of days, but its quality will deteriorate there much faster.
Wash your cauliflower under running water right before cooking. If you’re not using the whole head, cut off as much as you need and only wash that part. Don’t use soap, as some of it might get stuck in the florets.
Should you just toss the cauliflower head into the crisper drawer and be done with it, then? Not necessarily.
Cauliflowers keeps best in a cold and moist environment (UMN). While the fridge takes care of the temperature, it doesn’t provide the humidity. Sure, the veggie drawer is more humid than the rest of the fridge, but it’s still not an ideal setting.
The easiest way to fix that is to leave the head in a vented plastic bag. The bag will trap the moisture, but the holes help release the surplus.
Using unperforated bags or not leaving the top open is not a good idea. A well-sealed environment creates too much humidity, which leads to condensation. That, in turn, promotes the growth of microorganisms (UMN).
As you can tell, these practices are similar to how you store broccoli.
Once you’ve cooked the cauliflower, seal it in an airtight container and keep in the fridge.
If you need to keep the fresh cauliflower for an extended period, freezing is the way to go.
How To Freeze Cauliflower
I’m sure you’ve seen frozen cauliflower florets in the supermarkets’ freezers, so you know this veggie freezes quite well.
When it comes to the process, it’s a bit more time-consuming than just cutting the florets from the stalks and chucking them into the freezer.
Here’s how it goes (MSU):
- Prep the cauliflower(s). Trim off the leaves, and cut the head into florets. Wash them thoroughly. If you’re worried about insects, check out the tip below.
- Blanching. Bring a pot of water to a boil and blanch the florets for 3 minutes. The Michigan State University Extension suggests blanching in water with 4 teaspoons of salt added per 1 gallon of water (MSU). Still, many people blanch with no salt and are happy about it. Test both options if needed. You can read more about the process in our blanching FAQ.
- Cool and drain the florets. After blanching, transfer the florets into cold water and leave there for a couple of minutes, to stop the cooking process. Drain the water and pat the pieces dry.
- Portion and pack the veggies. Divide the florets into dish-size portions, and put each into its own freezer bag or airtight container. Seal everything tightly and add labels if you like.
- Put everything into the freezer.
If you’re worried about insects in the florets, soak them for half an hour in salty water, adding 4 teaspoons of salt per 1 gallon of water (MSU). Any insects that might be in the florets will die and float to the surface. Drain the water and continue with the freezing process.
Frozen cauliflower retains best quality for about 8 to 12 months (MSU).
In most cases, you will cook the frozen cauliflower, so more often than not, there’s no real need to thaw it. You can add it frozen, and that’s it.
But if you actually need to defrost it, do it in the refrigerator overnight.
How Long Does Cauliflower Last
Fresh cauliflower keeps quality for about 2 to 4 days at room temperature, and between a week and two weeks in the fridge.
Cooked cauliflower keeps for about 4 to 5 days in the fridge.
The storage time for a fresh cauliflower head depends on a couple of factors. Those include:
- storage conditions – if the bag was vented
- how long the head was stored before you’ve bought it
- overall quality – if there were any black spots when you’ve bought it, and the like
Because of that, it’s impossible to come up with a more specific estimate.
Cauliflower loses quality fast at room temperature, so it makes sense to leave it that way only if your fridge is full, or you plan on using it within a day or two.
|Cauliflower (fresh)||2 – 4 days||1 – 2 weeks|
|Cauliflower (cooked)||4 – 5 days|
How To Tell If Cauliflower Is Bad?
When checking if your cauliflower is okay to use, check for:
- Mold or large brown or black areas. If either is present, discard the head. Of course, if the “spoiled area” is quite small, you can cut it off (and then some) and use the rest, like many of us do for other veggies. Minor blemishes and imperfections are perfectly normal.
- Soft or slimy texture. Fresh cauliflower is firm to the touch. If yours has turned limp, it’s time for it to go.
- Off smell. If the head smells off, and you haven’t stored it near any smelly food item, there’s something wrong with it. Getting rid of it is the way to go.
As you can tell, cauliflower (and all of its varieties, including the standard white, and the more unusual ones like purple or orange) is no different than other veggies.
When it comes to cooked cauliflower, look for any signs of mold. And make sure you do so every time before using it.
Even though the cooked cauliflower often keeps well for up to a week, if you accidentally exposed it to microbes before refrigerating, it will go bad within a day or two.
Once or twice I’ve had cooked cauliflower that grew mold after being only two days in the fridge, so that’s definitely possible.
