How To Defrost A Turkey Crown. When defrosting a turkey crown do so in the fridge. Put in a roasting tin skin-side up and roast for 70 mins plus 20 mins per kg or until the internal temperature reaches 65-70C.

In a cool room below 175ºC 64ºF allow approximately three to four hours per kg or longer if the room is particularly cold. Heat the oven to 190C170C fangas 5. So for a 4kg turkey crown thats 16 hours.
Make sure to place the turkey on a deep tray or pot on the bottom shelf.
Remove the turkey from the oven and rest in a warm place for 20 mins. It doesnt matter if you cook your turkey from frozen or fresh you can use your leftovers to make a new meal. Have a look at your microwave manual if youve got one or set on the defrost function for 30 mins then for 5 min-bursts until defrosted. Mine is in a box and it tells you to take out 48hrs before and defrost in the fridge if thats any help.
