Best Philly Cheesesteak Sandwich Recipe

Heat large pan to medium heat, melt butter and toss in sliced onions, stirring around until soft and caramel colored, about 6-10 minutes. Remove from pan, set aside

If steak is not already sliced, slice as thinly as possible (see notes) and season with seasoning salt, not too much, just a light all over sprinkle

Using the same skillet, increase the heat to medium-high, add butter and oil, then add steak in as much of one layer as possible, if too crowded, do in a couple of batches. Cook for 1-2 minutes, then flip and cook the other side, for 1-2 minutes, won't take long, remove from heat

Once beef is browned (I slightly undercook, as it will keep cooking), pour in Worcestershire sauce and if desired, a few shakes of hot sauce we like Cholula. Stir around for a minute, then return onions to pan and stir into beef, including all of those delicious juices

Place desired cheese slices on top of the beef, cover for a minute until super melty, gooey, and irresistible, adding extra cheese if you like it really cheesy!

Meanwhile, heat a griddle or another large skillet to medium-high heat, spread a thin layer of butter on the cut side of the sub rolls, place butter side down on griddle and toast until brown and delish

Serve cheesesteak on top of rolls and enjoy immediately
