A traditional French dip sandwich doesn't include cheese. But, I like to add cheese, like Swiss or mozzarella, to my French dip for an extra layer of flavor.
No, cheese is not a traditional component of a French dip sandwich. While it's often added for extra flavor and richness, the classic version simply consists of thinly sliced roast beef on a baguette, dipped into a flavorful au jus.
