How Long Does Brussels Sprouts Last?

Brussels sprouts still attached to their stalk keep notably longer than loose, pre-trimmed sprouts, sometimes 3-4 weeks versus about a week for sprouts sold loose in a bag, since the stalk continues to protect and slightly nourish the sprouts even after harvest.

Yellowing outer leaves, a texture that's gone soft or slightly slimy, and loose leaves separating from the sprout's base are the early signs of decline. A strong sulfurous smell well beyond a sprout's normal mild cabbage-family scent, along with visible mold or dark, wet spots, mean it's actually spoiled — outer leaves that have yellowed but peel away to reveal a firm, pale green sprout underneath are often still perfectly fine once those outer leaves are removed.

Brussels sprouts left on their stalk at the store, rather than sold loose, are often fresher on average, since the stalk continues protecting them right up until purchase — buying stalk-attached sprouts when available and only cutting off what's needed extends the remainder's shelf life meaningfully.

A brussels sprout that's gone slightly soft at its base but stays firm through the rest of the sprout can often still be trimmed and used, since that softness is frequently just where it was cut from the stalk rather than a sign of spoilage spreading through the whole sprout.

A sprout stored away from strong-smelling foods in the fridge, like onions, avoids picking up an off-putting flavor transfer that can be mistaken for spoilage.
