Fresh Brussels sprouts last 3-5 days in a sealed container, and like broccoli and cauliflower, benefit from blanching before freezing to deactivate the enzymes that would otherwise keep degrading them in cold storage.
Brussels sprouts belong to the same plant species as cabbage, broccoli, and kale (Brassica oleracea) — all different cultivated varieties of one remarkably versatile species, bred over centuries to emphasize different parts of the same underlying plant, which is part of why they share a similar sulfur smell when overcooked or when starting to spoil.
Buying Brussels sprouts still attached to their stalk, when available, generally extends freshness compared to loose, pre-trimmed sprouts, since the stalk provides some of the same ongoing protection a whole cabbage head's outer leaves provide compared to pre-shredded cabbage.
A stalk kept in a cool spot, even briefly at room temperature before refrigerating, tends to hold up about as well as one refrigerated immediately.
A sprout that's been trimmed of its stem end right before storing tends to dry out slightly faster than one left with the stem intact until cooking.
Sprouts stored too long can develop a stronger sulfur smell even before cooking, a sign worth heeding even if the sprouts don't show other obvious spoilage signs yet.
A whole stalk of Brussels sprouts, with sprouts still attached, tolerates a day or two unrefrigerated better than sprouts already trimmed loose, since the stalk itself helps retain moisture around each sprout.
Smaller sprouts are often more tender and cook more evenly than very large ones, worth considering when selecting a bag or stalk at the store.
Sprouts purchased loose in a bag should be checked for any that are notably softer or more yellowed than the rest, since these decline fastest and can affect nearby sprouts.
A stalk of Brussels sprouts, if you can find one, keeps noticeably longer than loose sprouts and lets you harvest just what you need at a time.
Trimming any loose or yellowing outer leaves before storing helps the rest of the sprout stay fresher, since those outer leaves are usually the first to decline.
A Brussels sprout that feels noticeably light for its size compared to the rest of the batch has usually lost internal moisture and is past its best, even if its outer leaves still look green.

Frequently asked questions
How long do fresh Brussels sprouts last?
3-5 days is the realistic window for loose sprouts in a sealed container — leaving them still attached to their original stalk, when sold that way, actually stretches that a bit longer.
Do Brussels sprouts need blanching before freezing?
Yes — blanching deactivates enzymes that would otherwise keep degrading them even in the freezer, the same reasoning applied to broccoli and cauliflower.
Are Brussels sprouts related to broccoli and cabbage?
Yes, closely — all three (along with kale) are different cultivated varieties of the same plant species, Brassica oleracea, bred to emphasize different parts of the same underlying plant.
Does buying Brussels sprouts on the stalk help them last longer?
Yes, generally — the stalk provides ongoing protection similar to how a whole cabbage head's outer leaves protect it, compared to loose, pre-trimmed sprouts.
