What type of meat is used in the Meatloaf?

Meatloaf is traditionally made with ground beef, which is why the all-beef option is the correct choice. Ground beef provides a rich flavor and a satisfying texture that holds together well when mixed with other ingredients like breadcrumbs, eggs, and various seasonings. This combination allows the meatloaf to maintain its shape during cooking while also staying moist.

While chicken, pork, and turkey can certainly be used in meatloaf variations for those preferring lighter or different flavor profiles, the classic recipe most commonly recognized and served uses ground beef as its primary meat component. This is particularly true in traditional American recipes where the savory taste and moisture content are crucial for the success of the dish. Hence, the designation of "all-beef" accurately reflects the conventional preparation of meatloaf.
