Season the pink flesh side of the salmon with salt, pepper, and Old Bay. Heat a large skillet on high heat. Add the olive oil. Add the salmon skin side up to sear. Season the skin-side with salt, pepper, and Old Bay. Once the fish releases from the pan, flip. Put the skillet in the oven to finish cooking the fish, ~8 minutes (you want it a little on the rare side because it's going to get cooked again below). Remove from the oven and set aside.
