how long to cook chicken breast on grill

June 27, 2026

For boneless, skinless chicken breasts on a hot grill, plan on about 10–16 minutes total, but always cook to an internal temperature of 165°F (74°C) rather than by time alone.

Quick Scoop

Typical time:
- Medium breasts: 6–8 minutes per side on a 425–450°F (220–230°C) grill (about 12–16 minutes total).

* Some guides suggest around 9–10 minutes total, flipping halfway (about 4–5 minutes per side).

Goal: Thickest part reaches 165°F, then rest 5–10 minutes so juices settle.

Tools: A simple instant‑read meat thermometer is your best friend for perfectly cooked, juicy chicken.

Step‑by‑step timing guide

1. Prep and preheat

Preheat your gas or charcoal grill to medium‑high, roughly 425–450°F.

Pound thicker ends so the breast is a more even thickness; this helps it cook evenly and faster.

Pat dry and season, or marinate (from 15 minutes up to a few hours depending on your recipe).

2. Grill over direct heat

Place chicken on the hot grates over direct heat.
For most average‑size breasts, use this as a starting point:
- 6–8 minutes on the first side without moving it much.
- Flip, then 6–8 minutes on the second side.

Some grill guides use a slightly shorter window: about 5 minutes per side, 9–10 minutes total, flipping once halfway through.

If the outside is browning too fast but the inside is under 165°F, shift the chicken to a cooler or indirect‑heat zone and finish there for a few extra minutes.

3. Check doneness

Insert a thermometer into the thickest part:
- At 160–163°F, you’re nearly there.
- Pull it off the grill when it hits about 163–165°F; carryover heat will finish the job as it rests.

Let rest 5–10 minutes before slicing so the juices redistribute.

Time ranges by breast size

Use these as guidelines and adjust with your thermometer:

Small breasts (thin cutlets, 4–5 oz): 4–6 minutes per side (8–12 minutes total).

Medium breasts (6–8 oz): 6–8 minutes per side (12–16 minutes total).

Large/thick breasts (8–10+ oz):
- Sear 4–5 minutes per side over direct heat,
- Then move to indirect heat another 5–10 minutes until 165°F.

Wind, grill type (gas vs charcoal), and how often you open the lid will all nudge the timing up or down a little, which is why the thermometer matters more than the clock.

Mini pro tips (from home cooks and pros)

Flatten thicker ends slightly so the breast is more uniform and doesn’t dry out before the center cooks.

Keep one “hot” and one “cool” zone on charcoal: sear over the coals, finish on the cooler side with the lid on.

Many experienced grillers aim to avoid overcooking; some even pull breast meat a bit shy of 165°F and let carryover heat finish it during the rest for extra juiciness, but food‑safety guidelines still call out 165°F as the safe internal temp.

Quick TL;DR

Preheat grill to about 425–450°F.
Grill boneless chicken breasts roughly 10–16 minutes total, flipping once.
Always trust your thermometer: pull at about 163–165°F in the thickest part, then rest 5–10 minutes for juicy grilled chicken.
