How to Grill Boneless Chicken Breasts Without Drying Them

Boneless, skinless chicken breasts are lean and uneven in thickness, which is why they dry out so easily. This guide compares how Weber, AmazingRibs and America’s Test Kitchen handle it, and checks each against USDA’s 165°F minimum for poultry. Sources: Weber’s boneless chicken breast recipe, AmazingRibs’ pounding article and chicken guide, and two America’s Test Kitchen recipes. Celsius figures are our own conversions unless a source gives them.

Why the Cut Is Tricky

AmazingRibs describes the problem as shape: cook the thick bulge to a safe temperature and the tapered edges end up dry. Its fix is to flatten the meat so heat and any brine or marinade reach it evenly. America’s Test Kitchen’s “all-purpose” grilled breast recipe uses the same idea, pounding to ½ inch (about 1.3 cm) so the pieces cook at the same rate. AmazingRibs takes the meat to about ¾ inch (about 1.9 cm), pounding gently with a skillet or saucepan through plastic wrap or a zip-top bag rather than a mallet or rolling pin, which it says tend to tear the meat. Both note that thinner chicken cooks faster, so watch it. For really thin pieces, AmazingRibs also suggests slicing each breast horizontally into two halves before pounding.

Brine or Marinate

  • AmazingRibs: wet brines suit small, quick-cooking pieces such as skinless breasts. Its poultry-brine article gives 2 to 4 hours for chicken pieces, then a rinse and a thorough pat dry. In its lab comparison of chicken breasts, both wet and dry brining helped the meat hold water, with wet brining helping a little more.
  • America’s Test Kitchen: a 30-minute soak in a “brinerade” of salted water with fish sauce and honey, then oil on the chicken so it releases from the grate. Its other breast recipe uses a brine-and-oil mixture with garlic and sugar for 30 minutes to 12 hours.
  • USDA: for a basic brine, 3 tablespoons of salt per quart of water, refrigerated and covered, up to 2 days after purchase, and the brine discarded afterwards. USDA also warns that raw poultry labelled “marinated” or “self-basting” may already contain added solution (up to 8 percent by weight for boneless), and AmazingRibs says not to brine those products.

Weber’s recipe skips the brine altogether, brushing 8-ounce breast halves with oil and a dry rub of granulated onion and garlic, salt, chili powder and pepper. Weber’s 2013 grilling guide likewise puts boneless, skinless breasts of 6 to 8 ounces at 8 to 12 minutes over direct medium heat. That is the least fuss, but nothing in it protects the thin ends from drying, which is what the pounding and brining steps address.

Pick a Heat Setup

The three approaches are:

  • Direct medium heat. Weber’s recipe grills over direct medium heat (350 to 450°F, 177 to 232°C) with the lid closed, 8 to 12 minutes, turning once or twice. Its direct-grilling guide puts chicken breasts in a hotter medium-high band, 450 to 500°F (232 to 260°C).
  • Direct 400 to 450°F. AmazingRibs recommends this range for boneless breasts.
  • Indirect, then sear. America’s Test Kitchen’s brine-and-sear method starts the breasts on the cooler side under a disposable pan, then finishes them over the hot side. Its timings: 6 to 9 minutes on the cooler side, flip, 6 to 9 more until the chicken reads 140°F (60°C), then 2 to 4 minutes per side over the hot side for grill marks. America’s Test Kitchen’s all-purpose recipe found the breasts stuck to the grate and tore when flipped until it oiled them first.

The Temperature Question

USDA lists poultry, including breasts, at 165°F (73.9°C), and its guidance says to check the thickest part of the breast and to measure before removing food from the heat. The sources vary:

  • Weber’s recipe says 165°F, then rest 3 to 5 minutes.
  • AmazingRibs gives white meat as 160 to 165°F (71 to 74°C) and says the old “juices run clear” test is a myth, so use a thermometer.
  • America’s Test Kitchen’s recipes target 160°F (71°C); the indirect-then-sear recipe rests the chicken for 5 minutes.

The 160°F figures are below USDA’s minimum, so if you follow USDA, wait for 165°F in the thickest part before removing the chicken, then let it rest as Weber and America’s Test Kitchen suggest.

Putting It Together

Pound to an even thickness, brine or marinate in the fridge, dry and oil the surface, cook over a preheated grill, and use a thermometer rather than the clock. Every source’s timing is a guide, and thickness changes it.
