According to Exotic Meats, goose tastes like well-done roast beef. Goose tends to taste different from other types of game such as pheasant or wild turkey due to the fat content.
While goose does have a large amount of fat, the actual meat is lean and dark. When properly roasted, a goose has a very flavorful and rich taste. Unlike turkey, smaller geese are better than larger geese when it comes to roasting. According to NPR, an ideal goose will weigh between 8 and 12 pounds. NPR also recommends choosing younger geese since older geese often end up tough and unsavory.
