You’ll usually grill corn on the cob for about 10–20 minutes over medium‑high heat, depending on whether it’s husked, in husk, or wrapped in foil.

Quick Scoop

  • Husked, directly on grates: 10–15 minutes over medium‑high heat, turning every few minutes until lightly charred and tender.
  • In foil: about 12–16 minutes over medium‑high heat, turning every 3–4 minutes; this yields tender, lightly charred corn.
  • In husk: 15–25 minutes over medium to medium‑high heat, turning occasionally until kernels are bright yellow and cooked through.
  • Lower, gentler cook (thicker husks / fuller ears): can stretch closer to 30–40 minutes over medium heat if you leave husks fully on and let them steam.

Method Heat Time Range Key Signs It’s Done
Husked, direct on grates Medium‑high (around 375–450°F) 12–15 minutes Kernels bright yellow, lightly charred on all sides
Wrapped in foil Medium‑high (about 400–450°F) 12–16 minutes (some guides say up to 20–25 minutes) You hear sizzling, foil shows light grill marks; kernels tender
In husk, medium heat Medium to medium‑high (around 375–400°F) 20–22 minutes, sometimes 30–40 with thicker husks Husks browned/blackened outside, corn bright yellow to the cob
Simple quick grill (any method) Medium‑high 10–15 minutes total Corn hot, tender when pierced with a fork

Mini How‑To (With a Tiny Story Feel)

Imagine it’s a warm evening, grill already humming, and you’ve got a pile of corn waiting. You brush each ear with a bit of oil, maybe a pat of butter, and set them over medium‑high heat. Every few minutes you turn them, watching pale yellow kernels slowly pick up golden brown spots and a bit of smoky char. Around the 12‑ to 15‑minute mark, you poke a kernel with a fork, it gives gently, and a little burst of juice tells you they’re ready to come off the grates and straight onto the plate.

Quick Tips

  • Keep the heat at medium to medium‑high so the outside doesn’t burn before the corn is tender.
  • Rotate every few minutes for even cooking and char.
  • If you hear kernels popping or smell burning, pull them off right away.
  • Bright yellow, juicy kernels that pierce easily with a fork are your best doneness indicator.

“How long to grill corn” in most modern recipes boils down to: plan for roughly 15 minutes total, then let the look, smell, and tenderness of the kernels tell you when it’s perfect.
