First, preheat your oven to 400 degrees. In a large mixing bowl, combine the orange zest, thyme, butter, onion, and breadcrumbs to make the stuffing. Mix everything together well and set aside.

Next, carefully stuff the goose with the orange and thyme stuffing, making sure to pack it in firmly. Place the goose in a roasting pan and roast it in the preheated oven for about 2 hours, or until the skin is crispy and the meat is cooked through.

As the goose roasts, the skin will become crispy and golden brown, while the meat will be tender and juicy. The orange zest and thyme in the stuffing will infuse the goose with a delicious and aromatic flavor, making it absolutely mouthwatering.

Once the goose is cooked, let it rest for a few minutes before carving. This will allow the juices to settle and make it easier to carve.

When it's ready to serve, carve the goose into slices and arrange them on a platter, along with the stuffing. Serve the roast goose with your choice of sides, such as roasted potatoes, cranberry sauce, and steamed vegetables.
