Question: Can you eat cauliflower with black spots? Is it going bad? -Heather G.
Answer: Yes, cauliflower with small brown or black spots is often still safe to eat, but it depends on the severity of the discoloration.
Cauliflower naturally develops light brown freckle-like spots over time due to oxidation, a harmless reaction caused by prolonged exposure to light and air. These spots do not necessarily indicate spoilage and are more common in cauliflower that has been stored for a while.
How to Tell if Cauliflower is Still Good
- Light brown or yellowish spots → Safe to eat, but should be scraped or trimmed off.
- Dark brown or black spots → May indicate decay; inspect for other signs of spoilage.
- Mushy, slimy, or moldy areas → Not safe to eat. Discard immediately.
How to Fix Discolored Cauliflower
If your cauliflower has mild brown spots, you can easily remove the discolored areas before cooking:
- Use a sharp knife to scrape off the spots.
- Trim away any heavily discolored florets.
- Soak the cauliflower in vinegar water (1 part vinegar, 3 parts water) for a few minutes to reduce further oxidation.
How to Prevent Cauliflower from Turning Brown
To extend the freshness of your cauliflower and avoid discoloration:
- Store in the refrigerator in a loosely closed plastic bag or breathable container.
- Use within a week for the best quality.
- Keep dry—excess moisture speeds up spoilage.
- Blanch and freeze if you won’t use it soon.
Bottom Line:
Cauliflower with small brown spots is usually safe to eat as long as it isn’t mushy, slimy, or moldy. A quick trim can restore its appearance, and proper storage will help keep it fresher for longer!
