Q: What is the 7kg turkey cooking time in an Aga?
A: For slow roasting, plan about 10 to 12 hours in the simmering oven after 1 hour in the roasting oven. For fast roasting, between 3 and 3.5 hours in the roasting oven is typical.
Q: Should I stuff the turkey?
A: Stuff only the neck cavity or use an onion and butter in the body cavity so that it cooks more evenly.
Q: How do I keep the turkey moist?
A: Butter the skin, cover tightly with foil and a liner, and slow roast in the simmering oven for gentle heat.
Q: How do I know it is cooked?
A: The juices should run clear and the thickest part of the thigh should reach 74C.
Q: Can I hold the turkey for hours before serving?
A: Yes. Keep it wrapped in foil and insulated with towels on the warming plate or beside the cooker.
Turkey roasting times are always a hot topic at Christmas, and Aga cookers reward careful timing. This guide focuses on the timings and method so you can plan the day, whether you slow roast overnight or cook it faster in the roasting oven. Whether it’s a 7kg turkey or less, you will see clear guidance for various turkey sizes.
If the turkey weighs more than 16 lb (7kg), start it in the roasting oven for 1 hour to build heat, then transfer to the simmering oven overnight. If the turkey is under 7kg, place it straight into the simmering oven and let the oven do the rest.
See table below for more information:
| Weight | Slow roast time |
|---|---|
| 8 to 10 lb (3 to 4.5 kg) | 8 to 10 hours |
| 10 to 16 lb (4.5 to 7kg) | 9 to 12 hours |
| 16 to 22 lb (7 to 10kg) | 10 to 14 hours |
All Aga cookers run slightly differently, so use these timings as a guide and check earlier if your Aga is newer. Typically a 7kg turkey cooking time is between 10 and 12 hours with the slow roast method.
If the turkey is cooked by late morning and you plan to serve mid-afternoon, do not panic. Re-cover with foil and insulate with a folded bath towel. Keep it on the warming plate or beside the cooker and it will stay hot for hours.
For a faster cook, keep the turkey in the roasting oven for the full time. This gives a quicker roast and a deeper colour, but it needs more active attention.
See table below for turkey weight and roasting time:
| Weight | Fast roast time |
|---|---|
| 8 to 10 lb (3 to 4.5 kg) | About 2 hours |
| 10 to 16 lb (4.5 to 7kg) | 2 1/2 to 3 hours |
| 16 to 22 lb (7 to 10kg) | 3 to 3 1/2 hours |
