To cook a turkey breast on a gas grill, choose a cut that fits into the grill with at least an inch of space left between the breast and the lid, brush the unheated grill rack and the turkey with non-stick vegetable cooking oil, pre-heat the grill to 500 degrees Fahrenheit, and grill for about one hour and 45 minutes, or until the turkey breast reaches 170 F. Usage of the grill cover is recommended for even cooking.
Gas grilling allows food to be cooked directly over heat, which speeds up the cooking process. Turkeys less than 16 pounds are the ideal size for grilling on a gas grill, and vegetable cooking oil should be applied to both the cold grill and the turkey breast to prevent sticking. The clean grill must be pre-heated for 10 to 15 minutes or to around 500 F before the turkey breast is placed inside.
The grill cover should be used while cooking a turkey breast to ensure even heat distribution and to reduce the amount of fuel used. For a bone-in turkey breast that is between four and seven pounds, a cooking time of one hour and 45 minutes is recommended. The breast should reach an internal temperature of 170 F taken with a food thermometer. On cold or windy days, the cooking time might increase, while hot weather may decrease the time needed.
