Place steak on a flat surface and allow to come to room temperature while you make the spice rub (next step).
Mix together the sea salt, pepper, paprika, garlic powder, granulated onion, and coconut sugar in a small mixing bowl. This will be the seasoning you will add to the steak.
Generously coat the steak with the seasoning salt -- you will have left-over seasoning.
Heat a large, oven-safe skillet over high heat. Once hot, add the oil and allow to get hot.
Once oil is hot, place the seasoned steak in the pan and sear for 1 minute.
Flip and sear for an additional minute on the other side.
Place the pan into the oven and cook for 3 minutes.
Flip the steak and cook another 3 minutes in the oven.
Carefully remove the pan from the oven and then the steak from the pan.
Cover the steak with aluminum foil for 5 minutes.
This timing will result in the steaks being medium -- perfectly pink and juicy.
