Ideal Grilling Time for Boneless Chicken Breast

The average time to barbecue boneless chicken breasts is 6 to 8 minutes per side over medium-high heat.

The total time is 12 to 16 minutes but this depends on a few things:

• Thickness of the chicken

• Grill temperature

• Whether you’re using direct or indirect heat

To keep things simple, here’s a rule of thumb:

Grill over direct medium-high heat (about 400–450°F) for 6–8 minutes per side. 

Flip once halfway through.

Internal Temperature Is Key

No matter the time, the safest and best way to know your chicken is done is by checking the internal temperature. 

Use a meat thermometer and aim for 165°F (74°C) in the thickest part of the breast.

This ensures the chicken is cooked through — but not dried out.

Heads up! If you’re ever unsure about doneness, having a meat temperature guide close by can be a real lifesaver.

Should You Pound or Butterfly the Breast?

If your chicken breast is thick and uneven, one end may cook faster than the other. 

That’s where pounding it to an even thickness (about ¾ inch) helps. 

It ensures even cooking and reduces grilling time.

Butterflying is another option — cutting the chicken horizontally to make two thinner pieces. 

These can cook in as little as 4–5 minutes per side.

Tips to Keep Chicken Moist on the Grill

• Marinate first: Use a simple marinade (oil, acid like lemon or vinegar, and seasoning). Even 30 minutes makes a difference.

• Oil the grill grates: Prevent sticking and tearing.

• Don’t press it down: Pressing releases juices—leave it alone.

• Let it rest: After grilling, let the chicken sit for 5 minutes before cutting.
