Pre-heat the oven to 200C.
It is really important to take your goose out of the fridge early on the day you plan to cook it. You want to allow it to come up to room temperature so the meat isn’t shocked when you place it in the oven.
Using some kitchen towel pat the goose dry and ensure there isn’t any liquid lingering in the cavity.
Pull the wings and legs away from the goose, this allows the heat to circulate around the bird. With a skewer or the tip of a sharp knife, pierce the fattiest parts of the bird, being careful only to puncture the fat and not the flesh.
To stuff the goose, spoon your stuffing mixture into the neck cavity end of the goose, pressing it in as far as you can and then tucking the neck skin all around it and shaping it nicely with your hands. Secure the skin underneath with a skewer or a couple of cocktail sticks. When you’ve done that, rub the goose all over with the butter and season the bird all over with salt and pepper. Place the bouquet of herbs in the cavity of goose.
Place the bird on a wire rack and then place the wire rack into a large roasting dish. It is important to do this due to the copious amounts of fat in a properly free range goose, otherwise, the heat cannot penetrate the entire bird and it will stew in its fat.
Place the goose in the middle of the hot oven for 40 minutes.
Turn the oven down to 180C and cook for a further 20 minutes per kilo, basting occasionally.
Once cooked you can check the internal temperature of the meat. The breast should be about 60C, but if you like your bird well done cook it until it reaches a temperature of 72C.
Now remove the goose carefully to a large plate, cover and keep warm. Spoon out the hot fat (keep this in a jar in the fridge for next time, or use to make the best roast potatoes.
To carve the goose, remove the whole breast first, carefully slicing down each side of the breastbone with a sharp knife and gently easing the breasts away from the goose. Slice the breast across the grain into thick pieces. Then take the legs off at the base of the thigh and carve these in a more traditional way.
