Philly Cheese Steak Recipe

Prepare steak

Pat steak dry with paper towel. If not already thinly sliced, partially freeze steak for 30–40 minutes and slice as thin as possible against the grain into strips about 1/8" thick.

Place sliced steak in a bowl. Add vegetable oil, Worcestershire sauce, salt, and black pepper. Toss quickly to combine and let rest at room temperature while you prepare onions and bread (10–15 minutes).

Heat a large heavy skillet or griddle over high heat until very hot (a drop of water should sizzle and evaporate). Add 1 tbs vegetable oil and swirl.

Add the seasoned steak in an even layer. Let it sear undisturbed 30–45 seconds to develop color, then use a spatula to flip and sear the other side 30–45 seconds. Work quickly to avoid overcooking; you want tender strips with browned edges.

Once seared, use a spatula to chop and pull the steak into bite-sized pieces on the griddle. Remove from heat briefly while you finish onions and assemble cheese on the meat.

While the steak rests, cook bacon in a separate skillet over medium heat until crisp. Transfer to paper towels and cut each strip in half. Reserve 1 tsp bacon fat for onions if desired, otherwise use butter and oil.

In a medium skillet, heat 1 tbs butter and 1 tsp vegetable oil (or reserved bacon fat) over medium-low heat. Add the thinly sliced onions, a pinch of salt and pepper, and cook slowly, stirring every few minutes, until soft and deeply golden brown — about 12–15 minutes. If onions brown too quickly, reduce heat. Remove from heat and keep warm.

If onions finished before steak, keep them warm; if steak finished first, return steak to the hot skillet for 30 seconds to reheat before combining with cheese.

Butter the inside of the foot‑long roll lightly with the reserved butter (about 1 tbs). Toast the roll face down in a skillet or on a griddle over medium heat until golden and crisp, about 1–2 minutes. Remove and set aside.

Return the pan with the seared steak to medium-high heat. Spread the steak into an even layer and place the American cheese slices directly on top of the hot meat. If you want the cheese extra melty, cover the pan briefly (30–45 seconds) or place a metal bowl over the meat to trap steam and melt the cheese.

Using the spatula, scoop the cheesed steak onto the toasted roll. Top evenly with the caramelized onions and the halved crisp bacon strips. If desired, drizzle with a little olive oil or hot sauce to taste.

Close the sandwich, slice in half if desired, and serve immediately while hot.

Serve the Philly Cheese Steak hot. Provide napkins: the sandwich is rich and juicy. Leftovers can be reheated in a skillet over medium heat until warmed through; bread toasted separately for best texture.
