Bring the oven to 700 - 750 deg F using hickory and pecan wood. Remove 2 well-marbled, thick-cut, ribeye steaks from the refrigerator, and bring them to room temperature (approx. 1 hr 45 minutes on the counter.)
Drizzle oil on the steak (just enough so the seasonings will stick.)
Sprinkle with salt, pepper, and steak seasoning on both sides. Roll the edges of the steak in the seasoning as well. Press the seasoning into the meat. Note: The brown sugar in the steak spice will help give the meat a caramelized crust.
Place the streaks in a cool, well-seasoned, rust-free, cast iron skillet and put it in the hot oven. Cook for about 4 minutes on the first side. Flip the meat and cook for another 2 minutes on the second side. The goal is to bring them to about 120-125 degF before starting your basting. Note: By starting with a cold pan for thick steaks, it will help render the fat out of the meat without burning them. If you are cooking thinner steaks, you should use a preheated pan and reduce the cooking time.
Place the sticks of butter, rosemary, and garlic in the pan with the steaks. Allow the butter to melt. Using a metal ladle, spoon the butter and aromatic sauce over the steaks repeatedly to baste them. (Flipping the steaks to get both sides.)
When the meat has reached 135 deg F, remove the steaks from the pan to a cutting board. Pour any of the remaining butter sauce over the top. Allow them to rest before cutting and serving.
