The short version: how to store Brussels sprouts comes down to three things. So keep them unwashed, bag them loosely, and use the coldest, most humid corner of the fridge. NDSU Extension gives them 3 to 5 days there. Then trim the outer leaves instead of binning the sprout, and freeze what you will not cook this week.
Storage times here come from NDSU Extension, Clemson Cooperative Extension and University of Minnesota Extension, with the water-loss figures from Penn State Extension and the freezing method from the National Center for Home Food Preservation.

How do you pick Brussels sprouts that keep?
Pick sprouts that are small, compact and bright green, which is how Illinois Extension describes a good one. Tightness tells you most of it, because a loose sprout has been losing water since it was cut. Illinois also harvests them at no more than 1 to 1½ inches across. So check these four things before the bag goes in your basket.
Tight and heavy on the left; loose with yellow leaves on the right.
Glass, a lid that seals, and a spoon that is properly dry.
Firm, and no larger than 1½ inches. Illinois Extension harvests them at 1 to 1½ inches in diameter, while University of Minnesota Extension picks them at one inch.
Bright green, with no yellow cast. Illinois Extension harvests sprouts before the leaves yellow, so yellow in the shop means the clock started a while ago.
Freshness ahead of size. In fact, Clemson Cooperative Extension puts it plainly: the fresher the sprout the better the flavor. That is also why a whole stalk beats a bag.
Dry rather than damp, because University of New Hampshire Cooperative Extension warns that produce washed before storage may mold and rot more quickly. So a wet bag is already working against you.
How to store Brussels sprouts so they last
The whole of how to store Brussels sprouts comes down to cold, humid and unwashed. Humidity, however, is the part most guides skip. A limp sprout is simply a drier one, so the drawer decides how fast that happens.
Where should you store Brussels sprouts?
Brussels sprouts belong in the crisper drawer, unwashed and loosely bagged, at 32 to 40°F, which is University of Minnesota Extension's figure. Minnesota also stores them cold and moist, at 95 percent humidity. Humidity is the part people miss, and it is measurable. Penn State Extension recorded sprouts losing 1.6 percent of their weight a day at 32°F and 95 percent humidity. But at the same temperature and 80 percent humidity, the loss hit 6.4 percent a day. So the humid crisper is the right drawer, and a loose bag is the right container. That is the core of how to store Brussels sprouts. Penn State also names broccoli, not sprouts, among crops that yellow near high-ethylene fruit such as apples. So treat the fruit bowl as sensible to avoid, rather than a proven risk.
Unwashed, loosely bagged, and into the most humid drawer.
Sealed, cool and dark, and nowhere near the cooker.
How long do Brussels sprouts last in the fridge?
Brussels sprouts last 3 to 5 days in the fridge, according to NDSU Extension. So that is the figure to plan around. Published numbers disagree more here than for almost any other vegetable, though. For example, University of New Hampshire Cooperative Extension gives the crisper 1 to 2 days. Illinois Extension also caps storage at a day or two, because the fresher the sprouts the better the flavor. Clemson Cooperative Extension, however, gives one week. University of Minnesota Extension gives up to two weeks for sprouts cut from the stalk and bagged. Its harvest guide goes to a month, though, in cold and moist storage at 95 percent humidity.
That spread is not really a contradiction. The short figures are about flavor, since a fresher sprout simply tastes better. The long ones, however, assume cold, humid conditions a home fridge rarely reaches. In other words, how to store Brussels sprouts matters more than the number. So treat 3 to 5 days as the plan, and taste one before you trust a longer run.
Should you wash Brussels sprouts before storing them?
No, wash Brussels sprouts only just before you cook them, because University of New Hampshire Cooperative Extension says produce washed before storage may mold and rot more quickly. Illinois Extension also stores them unwashed, bagged, in the refrigerator's vegetable bin. Similarly, the National Center for Home Food Preservation rinses them only at the point of freezing. Have you washed them already? Then dry them with a clean paper towel, as New Hampshire advises. That is the same order the broccoli guide uses.
How do you store Brussels sprouts on the stalk?
Hang or stack the whole stalk upright in a cool cellar, which is what University of Minnesota Extension does once temperatures reach the mid-twenties. First it removes the leaves. Then it cuts the plant off at the soil surface. Sprouts come off that stalk over the following few weeks. A cellar is colder and more humid than a fridge, so it is the oldest answer to how to store Brussels sprouts. Otherwise cut them all off and bag them, since Minnesota gives those up to two weeks.
How do you store cut or shredded Brussels sprouts?
Cut Brussels sprouts keep about two days, covered, in the fridge: that is NDSU Extension's figure for prepared vegetables. Cutting opens up the inside, so a shredded sprout dries faster than a whole one. New Hampshire Extension puts cut, sliced or cooked produce in clean, airtight containers at 40°F or less. So shred them on the day you cook them. If a cooked tray sat out all evening, the food left out overnight hub covers that call.
Can you freeze Brussels sprouts?
Yes, and NDSU Extension gives frozen Brussels sprouts 10 to 12 months at 0°F. Clemson Cooperative Extension puts the figure at 12 months. So freezing is the long answer to how to store Brussels sprouts. Blanching is not optional, though, and the size sorting that goes with it is the step most people skip.
How do you freeze Brussels sprouts?
The National Center for Home Food Preservation freezes Brussels sprouts in five moves. First, choose heads that are green, firm and compact. Then trim the coarse outer leaves and rinse them thoroughly. Next, sort the heads into small, medium and large. Blanch them in boiling water by size: 3 minutes for small, 4 for medium, 5 for large. Cool them quickly afterwards and drain them. Then pack them with no headspace, seal, and freeze. Also check each head carefully for insects as you trim, because the National Center asks for that by name.
Sorted by size, because the blanching time changes with it.
Below 41 degrees it keeps for years, but it barely pours.
Do you have to blanch Brussels sprouts before freezing?
Yes, if you want NDSU Extension's 10 to 12 months, because the National Center for Home Food Preservation blanches every head before packing. Blanching is also why the sizes get sorted. A large head needs 5 minutes where a small one needs 3. So sort them while the water heats, instead of guessing one time for the whole bag.
How long do frozen Brussels sprouts last?
Frozen Brussels sprouts last 10 to 12 months at 0°F, according to NDSU Extension, and Clemson gives 12 months. Once they are cooked, however, the clock gets short. NDSU gives prepared frozen vegetables up to two days, covered, in the fridge. So pack them in meal-sized bags. Then you are not thawing a year's worth to roast one tray.
How can you tell if Brussels sprouts have gone bad?
Most of the sprouts people throw out are still fine once the outer leaves come off. Brussels sprouts fail from the outside in, because that is where the water goes first. Yellow leaves and a limp feel are quality stages, whereas slime and mold are the ones to bin. So how to store Brussels sprouts only takes you so far. The rest is knowing which stage you are looking at.
Verdict: use them
Firm, tight Brussels sprouts
Heavy, tight sprouts with bright green leaves and no give at all. Illinois Extension describes the pick as small, compact and bright green, so these are at their best. Roast them now, because Clemson says the fresher the sprout the better the flavor.
Verdict: trim and use
Brussels sprouts with yellowing outer leaves
A few outer leaves gone yellow or loose, with a firm sprout underneath. Illinois Extension removes damaged or irregular outer leaves before storing. It also harvests sprouts before the leaves yellow, so yellow means age rather than danger. So peel that outer layer off, then press the sprout to check it is still solid. The National Center for Home Food Preservation trims the coarse leaves anyway, even on fresh heads.
Verdict: cook them soon
Limp, shrivelled Brussels sprouts
Sprouts that feel light and give under a thumb have lost water rather than safety. Penn State Extension measured up to 6.4 percent of their weight going per day at 80 percent humidity. That is four times the loss at 95 percent, so a dry fridge does this in a couple of days. Shred them into a slaw or roast them hard, since heat covers a slack texture. Then fix the drawer rather than the sprout.
Verdict: cook them, seasoned harder
Bitter, strongly sulfurous Brussels sprouts
A harsh cabbage smell and a bitter edge, on a sprout that is still firm. That is usually the variety and the weather rather than spoilage. Illinois Extension says modern varieties were bred for higher sugar and lower glucosinolates, the compounds behind the sulfurous taste. It also says sprouts maturing in hot or dry conditions are more likely to taste bitter. University of Minnesota Extension adds that sprouts grown without steady moisture come out loose, poorly developed and too bitter. So roast them with fat and something acidic, instead of boiling them.
Verdict: throw them out
Slimy or moldy Brussels sprouts
Slippery leaves, a wet grey or black patch, or any fuzz at all. New Hampshire Extension says to check stored produce for signs of spoilage such as mold and slime, and to toss it out if spoiled. Cutting the mold away is not the answer here. New Hampshire warns that molds often produce toxins or poisons that can make a person ill, and that some are potentially cancer causing. So bin those sprouts. Then check the ones they were touching, the same way you would with cabbage.
Does frost really make Brussels sprouts sweeter?
Cool weather does improve them, and both garden guides say so plainly. Illinois Extension says sprouts improve in quality and grow best in cool or even lightly frosty weather. University of Minnesota Extension says flavor improves in cooler fall weather. Minnesota leaves plants in the garden as long as temperatures stay above 20°F, and calls sprouts one of the few crops usually harvested after snow has fallen. Neither source says frost sweetens a sprout already in your fridge, though. So a cold snap will not rescue a bitter bag. For that, Illinois points at variety and growing conditions instead.

Mistakes people make when they store Brussels sprouts
These are the ways people get how to store Brussels sprouts wrong, and each one has an easy fix.
Washing them as soon as you get home. New Hampshire Extension says produce washed before storage may mold and rot more quickly, so rinse them at the pan.
Leaving them out on the counter. NDSU marks pantry storage not recommended for Brussels sprouts, so they go straight into the crisper.
Keeping them in a dry fridge. Penn State measured four times the daily weight loss at 80 percent humidity as at 95 percent.
Binning a whole sprout over yellow leaves. Illinois Extension takes the damaged outer leaves off and keeps the sprout underneath.
Freezing them raw. The National Center for Home Food Preservation blanches every head first, 3 to 5 minutes depending on size.
Blanching the whole bag for one time. Small heads take 3 minutes where large ones take 5, so sort them first.
Shredding them days ahead of dinner. NDSU gives prepared vegetables about two days, covered, in the fridge.
