how long does it take corn to boil

For tender, sweet corn on the cob, it usually takes about 3–5 minutes in boiling water once the water has returned to a full boil.

Quick Scoop

• Fresh, husked corn on the cob: about 2–5 minutes in boiling water.

• Very fresh, super-sweet corn: often closer to 2–3 minutes , since the kernels are softer and cook faster.

• Unhusked fresh corn (boiled in husk): around 10 minutes.

• Frozen corn on the cob: about 5–8 minutes after the water returns to a boil.

• Frozen corn kernels: usually 2–3 minutes in boiling water.

A simple check: when the kernels turn bright yellow, look plump, and feel tender when poked with the tip of a knife or bitten, the corn is ready. Overcooking can make it mushy and dull in flavor, so it’s better to start checking early.
