For average boneless, skinless chicken breasts on a hot grill, plan on about 10–15 minutes total, but always cook to an internal temperature of 165°F (74°C), not just by time.

Quick Scoop: Time & Temperature

  • Preheat your grill to medium‑high, around 425–450°F.
  • Grill boneless chicken breasts 5–8 minutes per side (about 10–16 minutes total), depending on thickness.
  • Use a meat thermometer and remove the chicken when the thickest part hits 160–165°F, then rest 5 minutes so it finishes reaching 165°F and stays juicy.

Thickness matters

  • Thin cutlets: often done in 4–6 minutes per side (8–12 minutes total).
  • Standard breasts: 6–8 minutes per side (12–16 minutes total).
  • Very thick breasts: consider pounding or butterflying first so they cook more evenly and don’t burn outside before the center is done.

Simple step‑by‑step

  1. Preheat grill to 425–450°F and oil the grates.
  1. Pat chicken dry, season or marinate, and let it sit at room temp 15–20 minutes.
  1. Grill 5–7 minutes, then flip.
  1. Grill another 5–7 minutes, adding BBQ sauce during the last few minutes so it doesn’t burn.
  1. Check the thickest part with a thermometer; once it’s 160–165°F, move to a plate and rest 5 minutes before slicing.

Bottom line: don’t just watch the clock—watch the temperature.
