You only need a few minutes of boiling for sweet, tender corn on the cob.

Quick Scoop

  • Fresh husked corn on the cob: about 3–5 minutes in boiling water until bright yellow and tender.
  • Very fresh, super-sweet corn: as little as 1–3 minutes once the water returns to a boil, so it stays crisp and juicy.
  • Frozen corn on the cob: around 5–8 minutes in boiling water.
  • Frozen corn kernels: about 2–3 minutes in boiling water.

Simple step-by-step

  1. Bring a large pot of water to a rolling boil.
  1. Add shucked corn cobs.
  2. Start timing once the water comes back to a boil:
    • 3–5 minutes for fresh husked corn.
  1. Check by poking a kernel with the tip of a knife; it should be tender but not mushy.
  1. Turn off the heat, drain, and serve with butter, salt, and pepper.

Small extra tips

  • Don’t overboil, or the corn can turn mushy and lose sweetness.
  • If the rest of your meal isn’t ready, you can turn off the heat and let the corn sit in the hot water for a short while to keep warm.

TL;DR: For fresh corn on the cob, aim for about 3–5 minutes in boiling water for the best balance of tenderness and crunch.
