How Long to Grill Chicken Breast
By The Recipes by Mom kitchen · Last checked October 21, 2026 · Not kitchen-tested; see how our recipes are made
Grilling time for chicken breast depends on its thickness and whether it is bone-in or boneless. According to USDA guidelines, a typical 4-ounce boneless chicken breast half will cook in about 6 to 8 minutes per side over direct medium heat. A larger, 6 to 8-ounce bone-in breast half takes longer, about 10 to 15 minutes per side.
These times are a starting point. The single most important factor for safely cooked and juicy chicken is not the clock, but the internal temperature. A food thermometer is the only reliable way to know when chicken is done.
How Long to Grill Chicken Breast: time chart
| What | Heat | Time | Done when |
|---|---|---|---|
| Boneless breast half (USDA chart, 4 oz) | Direct medium heat | 6 to 8 minutes per side | 165°F |
| Bone-in breast half (USDA chart, 6 to 8 oz) | Grill | 10 to 15 minutes per side | 165°F |
| Thick boneless breast, pounded even | Direct medium-high heat | 5 to 7 minutes per side | 165°F |

Good to know
- Pounding to an even thickness prevents dry edges
- Discard marinade that touched raw chicken, or boil it before using as a sauce
What affects the grilling time
Several factors determine how long a piece of chicken will take to cook through on the grill. Understanding these variables will help you use the time estimates as a guide rather than a rule.
- Thickness: This is the most critical factor. A very thick breast will take much longer to cook to the center than a thin one. If a breast is uneven, with one thick end and one thin end, the thin part can become dry and overcooked before the thickest part is safe to eat. Pounding the chicken to a uniform thickness helps it cook evenly.
- Bone-in or Boneless: As shown in the cooking chart, bone-in chicken breast requires significantly more time on the grill. The bone acts as an insulator, slowing the transfer of heat to the meat around it.
- Grill Temperature: The provided times are based on specific heat levels, such as direct medium or medium-high. A grill that is too hot can char the outside of the chicken before the inside is fully cooked. A grill that is not hot enough will extend the cooking time.
How to tell when chicken is done
Appearance and time are not reliable indicators of doneness. The only way to ensure chicken is cooked safely is to use a food thermometer. According to the USDA, all poultry, including chicken breast, must reach a minimum internal temperature of 165°F (74°C) to be safe to eat.
To check the temperature correctly, insert the thermometer into the thickest part of the breast, being careful not to touch any bone. For an uneven breast, check the temperature in the thickest section. Once the chicken reaches 165°F, remove it from the grill immediately to prevent it from overcooking and becoming dry.
Tips for better grilled chicken
A few simple techniques can produce better results when grilling chicken breast.
- Pound for even thickness. Placing a chicken breast between two pieces of plastic wrap and gently pounding it with a meat mallet or rolling pin creates a piece of uniform thickness. This helps prevent dry, overcooked edges while the center cooks through. An evenly pounded breast will also cook faster, in about 5 to 7 minutes per side.
- Manage marinades safely. If you use a marinade, it can add moisture and taste. However, any marinade that has come into contact with raw chicken is not safe to use as a sauce. To use it, you must first bring it to a full boil to destroy any harmful bacteria. Otherwise, it is best to discard it.
