Type of corn How long to boil Notes
Fresh corn, husked (no leaves) 2–5 minutes in boiling water Most home cooks like 3–5 minutes for tender, juicy kernels.
Very fresh, sweet corn About 2 minutes The sweeter and fresher it is, the faster it cooks.
Fresh corn, unhusked (in husk) About 10 minutes Boil 10 minutes, or add to boiling water off the heat and let sit 10 minutes.
Frozen corn on the cob 5–8 minutes Drop into boiling water; cook until heated through and tender.
Frozen corn kernels 2–3 minutes Boil just until hot and tender so they don’t get mushy.

Simple step‑by‑step (fresh husked corn)

  1. Fill a large pot with enough water to cover the corn by about 2–3 cm.
  2. Bring the water to a full, rolling boil.
  3. Add the shucked corn, return to a boil, then cook 3–5 minutes until bright yellow and tender.
  1. Remove, drain, and serve with butter, salt, and pepper.

A nice “set and forget” variation is to add shucked corn to boiling water, turn off the heat, cover, and let it sit in the hot water for about 10 minutes; the corn stays warm and comes out tender without overcooking.

TL;DR: If you’ve got regular fresh corn with the husk removed, aim for about 3–5 minutes once the water is boiling, and you’ll be in the sweet spot.
