01 - Set the oven to 350°F (180°C) to prepare for roasting.
02 - Generously season the inside and outside of the goose with salt and black pepper.
03 - Fill the goose cavity with apple quarters, onion segments, rosemary, and thyme sprigs.
04 - Secure the legs with kitchen twine and tuck the wings under the body to maintain shape.
05 - Place the goose breast-side up on a rack in a large roasting pan. Prick the skin evenly with a sharp knife to facilitate fat rendering.
06 - Roast for 2 to 2½ hours, basting occasionally with the rendered fat. Cover loosely with foil if the skin browns too quickly.
07 - After the first hour, spoon off excess fat and reserve for alternative uses such as roasting vegetables.
08 - Once golden and juices run clear, transfer the goose to a platter, cover with foil, and allow to rest for 20 minutes.
09 - Discard most fat from the roasting pan, leaving approximately 2 tablespoons. Over medium heat, add white wine and scrape up browned bits. Incorporate stock and simmer until reduced by half. Optionally, whisk in flour to thicken and strain before serving.
10 - Carve the goose and serve accompanied by the prepared gravy.
