Philly Cheese Steak

Philly cheesesteak is one of those sandwiches that always hits the spot, especially after a long day. Those thin slices of juicy beef, sautéed peppers, onions, and melted cheese, all nestled in a fresh sandwich roll, is truly magnificent. But have you ever tried making it on a Blackstone griddle? The flat-top grilling method takes this iconic sandwich to a new level of deliciousness, making it one of the best choices for a quick and filling weeknight meal.

Do flat-top grills make grilling easier?

Busy weekday schedules demand quick and easy meals. That’s where a flat-top grill (or griddle) really shines. With its large flat surface and even heat distribution, you can quickly cook thin sliced meat for Philly cheesesteak sandwiches, vegetables, pizza, smash burgers, and pancakes. Grills like Blackstone, Razor, Weber, etc., can handle multiple components simultaneously, ensuring a fast, hot meal for you and your loved ones.

Philly cheesesteak 101

  • Choosing the right steak: Use cuts like ribeye or sirloin for making the perfect Philly cheese steak sandwich. These steaks are tender and easy to bite into when sliced thinly.
  • The best cheese: The gooey, melted cheese is one of the best parts about these sub sandwiches. Provolone is the traditional choice, but other cheese slices like American, Swiss, havarti, or even pepper jack are also great.
  • The veggies: Sautéed bell peppers and onions are integral to the Philly cheese steak experience. On the flat-top grill, you’ll achieve great caramelization that adds depth to these sandwiches. Remember to slice the veggies thin before cooking them. Add a delicious kick with pickled jalapeno or pepperoncini slices, or a infuse a little umami flavor with sauteed mushrooms.
  • Sandwich Rolls: Use soft but sturdy rolls that can hold up to the delicious filling. Lightly toast the rolls with a little butter for a slight crunch and help the bread from becoming soggy and falling apart.
  • Side Dish Suggestions: Serve these steak sandwiches with french fries, sweet potato fries, onion rings, potato chips, salad, or coleslaw.

  • Heat the remaining 1 tablespoon of oil.
  • Once hot, spread the thinly sliced steak in an even layer. Let them cook for 1-2 minutes per side or until they are nicely seared.
  • Next, split the meat into 4 equal parts.

  • Spread a layer of mayonnaise, or your favorite condiment, on the inside of each sandwich roll. 
  • Lay two slices of cheese on the bottom half of each roll.
