How to Grill Chicken Breast Without Drying It Out

Chicken breast has a narrow window. It goes from underdone to safe to dry across a span of about fifteen degrees, and unlike a steak there is no doneness preference to fall back on — poultry has one number, and it isn’t optional. That’s why chicken breast punishes guesswork more than anything else on a grill.

The real problem: uneven thickness

A supermarket chicken breast is not a uniform object. One end is often twice as thick as the other, which means by the time the thick end reaches a safe temperature, the thin end has been sitting well past it for several minutes. That thin end is the dry, stringy part people blame on the grill.

The fix takes thirty seconds. Put the breast between two sheets of baking paper or in a bag and press or pound the thick end down until the whole piece is roughly even — about three-quarters of an inch works well. You are not tenderizing it; you are making it one thickness so it cooks as one thing. This single step does more for grilled chicken than any marinade.

Salt early if you can

Salting 40 minutes ahead (or the night before) lets the salt draw moisture out and then back in, seasoning the meat rather than the surface and helping it hold on to water during cooking. If you only have five minutes, salt anyway — it’s still better than salting at the table.

A wet marinade is optional and mostly flavors the outside. If you use one with sugar or honey in it, expect it to burn over direct heat; move to the cooler zone earlier than you otherwise would.

The method

Build a two-zone fire — hot on one side, nothing or low on the other. Start the chicken over the direct side to get color, about 5 to 7 minutes a side depending on thickness. If it’s browning faster than it’s cooking, which is common on a hot grill, move it to the cooler side and close the lid to finish gently.

Then check the temperature. Probe the thickest part, avoiding the grate, and pull at 165°F. Chicken doesn’t carry over as dramatically as a thick steak, so there’s no need to pull far early — but do rest it five minutes, because the juices need to settle.

Times are a guide only — thickness and grill heat vary enormously. The number is the number. That is exactly the case for owning an instant-read thermometer, which costs about fifteen dollars and removes the entire problem.

Why 165°F, and why people go under

165°F is the USDA safe minimum internal temperature for poultry, and unlike beef doneness it isn’t a preference — it’s the food-safety line. You will see cooks online argue for pulling chicken breast lower on the basis of time-at-temperature pasteurization. We don’t give food-safety advice of our own: the USDA number is the one we publish, and it’s the one to cook to.

If you want chicken with more margin for error, cook thighs instead. They have more fat and connective tissue and stay juicy well past the safe minimum — see our guide to grilling chicken thighs.
