Preheat the Blackstone griddle over high heat (approximately 450 degrees F). You want the griddle to be hot to get a good sear on the steaks.

Make sure that the flank steak is dry and are at room temperature.

Combine the garlic powder, Italian seasoning, salt and pepper together in a small bowl. Then season the steaks with the seasoning mixture on both sides of the steak.

Spread the oil out onto the Blackstone grill.

Place the flank steak on the Blackstone grill. Cover and cook for approximately 5 minutes to get a good sear on the steak.

Then use tongs to gently lift and flip the steak.

Cover and cook the other side for approximately 4-5 more minutes.

Then reduce the temperature on the Blackstone grill to medium heat. Cook the steak until it is done to your preference. Use an instant read meat thermometer to check the steak temperature. The recipe notes at the bottom has the internal temperature for each steak preference.

Remove the steak from the grill.  Loosely cover the steak with foil and let the steak rest for 10 minutes and then it is ready to slice, serve and enjoy!
