01 - Set the oven to 350°F (180°C) to prepare for roasting.
02 - Pat the goose dry with paper towels, trim excess fat from neck and cavity, then season both inside and out with 2 teaspoons kosher salt and 1 teaspoon ground black pepper.
03 - Place the quartered orange and onion inside the goose cavity for added flavor.
04 - In a large bowl, mix bread cubes with melted butter, then incorporate chopped onion, celery, apples, parsley, sage, thyme, and marjoram. Stir in the beaten egg and chicken stock, seasoning with salt and pepper to taste.
05 - Fill the goose cavity loosely with the herb mixture, avoiding overpacking. Reserve extra stuffing to bake separately if desired.
06 - Tie the legs together with kitchen twine and tuck wings underneath to maintain shape during roasting.
07 - Place the goose breast-side up on a rack within a large roasting pan and pour 1 cup water into the pan.
08 - Cook for 2 hours and 30 minutes, basting every 30–40 minutes with pan juices. After the first hour, prick the skin with a fork avoiding meat to render fat and crisp skin evenly.
09 - If skin browns excessively, loosely cover with foil to prevent burning.
10 - Verify the internal temperature reaches 165°F (75°C) in the thickest part of the thigh to ensure thorough cooking.
11 - Let the goose rest, loosely covered, for at least 20 minutes before carving. Serve alongside herb stuffing and optionally garnish with fresh herbs.
