Blackstone Philly cheesesteak - featured image

A quick and easy Philly cheesesteak made on a Blackstone griddle featuring thinly sliced ribeye steak, sweet caramelized onions, and melty provolone cheese on toasted hoagie rolls. Perfect for a hearty, flavorful meal with a smoky twist.

Ingredients

Scale
  • 1 pound ribeye or top sirloin steak, thinly sliced
  • 2 large yellow or sweet onions, thinly sliced
  • 68 slices provolone cheese
  • 4 hoagie rolls or Amoroso rolls
  • 2 tablespoons olive oil
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 1 teaspoon garlic powder
  • 1 tablespoon Worcestershire sauce (optional)
  • 1 tablespoon butter

Instructions

  1. Thinly slice the steak against the grain. Peel and slice the onions into thin half-moons. Toss the steak in a bowl with salt, pepper, garlic powder, and Worcestershire sauce. Let it sit while heating the griddle.
  2. Preheat the Blackstone griddle to medium-high heat (around 375°F). Add 1 tablespoon olive oil and spread evenly.
  3. Add onions to the griddle, season lightly with salt, and cook, stirring occasionally for 15-20 minutes until soft, brown, and caramelized. Stir every few minutes to avoid burning; add a splash of water or reduce heat if sticking.
  4. Push onions to one side. Add remaining olive oil, then spread steak slices in a thin, even layer. Let sear without overcrowding. Flip and stir after 3 minutes until cooked through and slightly browned (5-7 minutes total).
  5. Mix the cooked steak and onions together. Layer provolone slices on top and cover with a metal dome or tent aluminum foil to melt cheese evenly for 2-3 minutes.
  6. Spread butter on cut sides of rolls. Move them to the griddle edges and toast until golden and crispy, about 2 minutes.
  7. Using a spatula, scoop the cheesy steak and onion mixture onto the toasted rolls. Serve hot.

Notes

Don’t rush the onions; slow caramelizing develops sweetness. Use a metal dome or foil tent to melt cheese evenly. Toast rolls with butter for a crispy crust. If you don’t have a Blackstone griddle, a cast iron skillet or flat-top griddle pan can be used but won’t get the same char. For gluten-free, substitute rolls with gluten-free buns and ensure Worcestershire sauce is gluten-free.
