How long to cook two 6lb turkey breasts bone in same time?

To cook two 6-pound bone-in turkey breasts, preheat your oven to 325°F (165°C). Roast the turkey breasts for about 1.5 to 2 hours, or until the internal temperature reaches 165°F (74°C). It's important to check the temperature in the thickest part of the breast to ensure they are fully cooked. If they are cooked together, they should take roughly the same amount of time as cooking one.
