How to Tell If Broccoli Is Bad
Quick answer
Bad broccoli turns yellow, slimy, and soft, with dark mushy spots and a strong sulfur smell. A limp stalk or slightly yellow florets can still be used if there’s no slime or mold.
Signs Broccoli has gone bad
- Slimy or mushy florets. A slick coating or crumbling, mushy buds means spoilage. Toss the head if rot has spread beyond a small area.
- Dark, black, or brown spots. Small dry brown tips can be trimmed, but wet black spots signal rot. Cut them out only if the rest is firm and clean.
- Strong sulfur or rotten smell. Raw broccoli smells faintly cabbage-like. A heavy rotten-egg or sour odor means it’s gone off.
- Fuzzy white or gray mold. Mold between the florets or at the cut end means you should discard it, since the dense heads hide spread.
- Widespread yellowing. A few yellow flowers are fine to trim away. If the whole head is yellow, it’s old and bitter, and may be starting to rot.
- Very limp, hollow stalk. A rubbery stalk is just dehydrated, but a hollow, brown, or wet-centered stalk is in decline. Cut it open and check for decay.
Looks weird, but it's fine
- Slight yellowing on a few florets. A little yellow means it’s aging and will taste stronger. Trim and cook it.
- Limp stalk. Trim the end and stand the stalk in cold water, or cook it as it is.
- Purple-blue tint. Some varieties have a purplish hue that fades when cooked. It’s natural, not a sign of spoilage.
How long does Broccoli last?
| Where | How long | Note |
|---|---|---|
| Fridge | 3–5 days | raw, unwashed |
| Fridge | 3–5 days | cooked |
| Freezer | 10–12 months | blanched florets |
How to store it
- Keep broccoli unwashed in an open or perforated bag in the crisper drawer.
- Wash right before cooking. Damp florets turn slimy quickly.
- Blanch for 2–3 minutes, cool, dry, and freeze extras. They’re ideal for soups and stir-fries.
Use it up before it turns
Frequently asked questions
Can you eat broccoli that has turned yellow?
Slightly yellow florets are safe, just more bitter. If the yellowing is widespread or the broccoli is slimy or smells strong, throw it away.
Why does my broccoli have black spots?
Small, dry dark spots may be minor bruising or mold beginning. If they’re wet, fuzzy, or spreading, discard the head.
Is limp broccoli bad?
Not necessarily. A limp but clean-smelling head can be revived in ice water or cooked. Limp plus slimy or smelly means toss it.
