  • 2 24-ounce Porterhouse Steaks ROOM TEMPERATURE
  • 1-2 tablespoons Olive Oil
  • Kosher Salt
  • Freshly ground black pepper


  • Heat the gas or charcoal grill to high (450-500 degrees). Brush and oil the grilling grate.
  • Brush the steaks with a light coat of olive oil. Salt and pepper the steaks.
  • Place the porterhouse steaks on the hot grill and allow to sear for 2 ½ minutes. NOTE: for medium doneness steaks increase the time interval to 3 minutes for each segment.
  • Rotate the steaks 45 degrees and grill another 2 ½ minutes (this will get the cross hatch grill marks).
  • Flip the steak with tongs and sear another 2 1/2 minutes. Rotate 45 degrees and grill a final 2 ½ minutes. Check the temperature with an instant read thermometer.
  • Remove the steaks from the grill and allow them to rest for 5-10 minutes before serving.


Start with steaks close to room temperature. Remove them from the refridgerator 2 hours before grilling.
Grilling time:
  • Steaks will cook 5 minutes per side (2-2 1/2 segments) for Medium Rare
  • For Medium, cook 6 minutes per side (2-3 minute segments).
