A turkey crown takes around 20 minutes per pound to cook. A 10  pound turkey crown will take at least 3 hours and 20 minutes.ow long do you cook a 10-12 lb precooked turkey? 2 to 2 1/2 hours. if you want a brown brittle skin,baste in butter every 20 minutes.
The next step is to calculate the cooking time. The target...MORE temperature for the grill is between 325 to 350 degrees F/160 to 175 degrees C so the cooking time is 15 to 20 minutes per pound (500g), so do the math first. This will determine the amount of fuel needed and for how long the grill will need to burn. Just as a general guideline and calculated on the safe side, a 12-pound (5.5 kg) turkey will take 4 hours and a 15-pound (7 kg) turkey will take 5 hours.
