The case for making a Blackstone Philly Cheesesteak is pretty simple. The hot griddle gives you the seared ribeye, browned onions, toasted hoagie, and melty cheese. That's hard to pull off easily in a single skillet. I use thinly sliced ribeye and diced onions. A splash of water under the dome at the end gives the cheese has no choice but to go gooey
Season the steak with salt and pepper and allow to sit at room temperature for 1 hour.
Heat the Blackstone Griddle to medium heat.
Toast your hoagies, cut side down. Transfer to a baking sheet and cover with foil to keep warm.
Oil the griddle well.
Add onion on one side and cook for 5 minutes.
Add the steak to the other side of the griddle.
Cook until browned and cooked through, about 3 minutes. Combine the steak and onions.
Add the cheese to the top of the steak and cover, adding a touch of water to the hot surface just before you close the dome.
Cook until the cheese melts, about 30 seconds.
Fold the cheese into the steak.
Form sandwiches with the rolls, steak and onions.
