Take shoulder steaks out of fridge 30 minutes before cooking. Preheat oven to 400 degrees F. Heat cast iron pan over medium high heat with olive oil.
Blot steaks with paper towels to dry outside, on both sides. Sprinkle 1/2 dry seasonings on top. Wait for skillet to become hot and place side with dry rub on the bottom to sear for 2 min. Then sprinkle the other half of your rub on the top. Flip and sear on the other side for 2 min.
Set this cast iron pan into the preheated oven for 10 minutes. Lift out when done, test to ensure they are 145F. and leave in skillet for 5 minutes before serving so they can rest.
