Hoagie roll

In American usage, a hoagie roll is a long, crusty-on-the-outside, soft-on-the-inside bread roll used to prepare hoagie sandwiches, particularly in the Philadelphia area.^[1][2][3] Also known as a "sub" or "hero" roll. Key characteristics include a firm exterior that holds up to fillings and a tender interior. They are the foundation for classic sandwiches with cold cuts, cheese, and oil, vinegar, and oregano. Hoagie rolls are sometimes toasted before being used to prepare a sandwich.^[4][5]

Ingredients used in hoagie roll preparation may include flour, eggs, milk, vegetable oil, salt, sugar, and yeast.^[1][3] Some versions include sesame seeds atop the roll, which may add extra flavor and textural elements.^[6] Gluten-free^[7] and vegan^[8] hoagie roll recipes have been devised.

The hoagie roll is used to prepare the Philadelphia cheesesteak sandwich^[9][10][11] and various other submarine sandwiches.
