What kind of bread is usually used to make a Reuben sandwich?

The traditional bread for a Reuben sandwich is marbled rye bread.

This bread is known for its slightly sweet and tangy flavor, its dense texture, and the characteristic marbling that comes from the addition of caraway seeds. The marbling helps to absorb the juices from the corned beef and sauerkraut, creating a delicious and satisfying sandwich.

While marbled rye is the classic choice, you can also use other types of rye bread or even sourdough bread for a slightly different flavor.
