National Cheesesteak Day, celebrated annually on March 24, pays tribute to the iconic sandwich. It’s become a symbol of Philadelphia's rich culinary heritage, and offers both Philly locals and enthusiasts nationwide an opportunity to indulge in this savory delight – and honor its rich past.

Heat a little oil in a pan, then caramelize the onions with a pinch of salt until they turn golden brown. This should only take a couple of minutes—s tir occasionally to ensure even cooking and to keep them from sticking or burning.

National Cheesesteak Day is celebrated on Monday, and POP's Philly Steaks is hosting its second annual cheesesteak eating competition in Las Vegas, with the winner receiving free cheesesteaks for a year.
