Philly cheesesteak is right on top of America's most iconic sandwiches. Thin-sliced beef, sauteed onions, and gooey melted cheese on a thick, hearty bread roll, there is one secret ingredient that would make Philly cheesesteak even more delicious.

Philly native and true cheesesteak connoisseur Chris Pinto of the Tiki Lounge Talk blog adds garlic powder for some extra flavor. His secret is to sprinkle the garlic onto the sliced roast beef before finishing it with onions, sliced provolone, or mozzarella.

Pinto not only likes to season the beef with garlic powder, but he also uses garlic powder or fresh garlic to dress up the butter he uses on the sandwich bread. This method was used at a Philly restaurant called Jake's Sandwich, which made "Garlic Bomb," a famous cheesesteak named one of America's best new sandwiches for 2012 by the EndlessSimmer food blog.

Even celebrity chefs approve of the garlicky cheesesteak trend. Rachael Ray created a recipe for a Philly Cheesesteak-Stuffed Garlic Bread, while Bobby Flay's Mini Open Faced Steak Sandwiches on Garlic Bread with Aged Provolone and Parsley Oil are a fancy, appetizer-sized, garlicked-up version of Philly's favorite sandwich.

There are many variations to this famous Philly sandwich. One of these is to use Cheez Whiz instead of the standard cheese choices, while another is to add mushrooms and other condiments such as mayo, ketchup, or mustard.
