Tips for Grilling Boneless Chicken Thighs

Marinate your chicken thighs: we swear by marinating chicken thighs because it infuses the poultry with so much flavor.

Pro tip: set aside about 1/4 cup of marinade so that you can glaze the chicken with it right before removing it from the grill!

Oil grill grates: by rubbing oil onto your grill grates, you help prevent your chicken thighs from sticking.

Grill over medium/high heat: cook the thighs at around 400ºF for around 4-5 minutes on each side.

Grill over direct heat: we prefer grilling boneless chicken thighs over direct heat so they get those gorgeous char marks.

Cook until 160ºF: if you remove the thighs when the internal temperature reaches 160ºF, they will continue cooking as they sit about 5 more degrees.

Let rest: make sure to let the chicken thighs rest for around 5-10 minutes after you remove them from the grill so that they can continue cooking around 5 more degrees.
