Hoagie Roll – The traditional bread for a Philly cheesesteak is a soft, yet sturdy hoagie roll. It should be long enough to hold the filling, typically about 6-12 inches.
Crispy Exterior – While the interior is soft, the exterior should have a slight crispiness or firmness to prevent the sandwich from getting soggy.
Toasted Option – Some prefer to lightly toast the bread for added texture and to keep it from becoming soggy from the juicy steak and cheese
Absorbency – The bread should be able to soak up some of the steak juices without becoming overly soft or disintegrating.
