Neighbor is a chef. Best advice he gave me is hot cast iron grates. Sears juices in better than chrome rod grilles. Also make the cool sear lines on the steak, crisscross one if you do it right. I just use garlic pepper and a little salt. I want to taste the steak. If a waitstaff asks if I want steak sauce. I tell them you can take it back if it needs steak sauce. Surprised no one mentioned a couple pats of butter, I don’t. But cheap way to upgrade a lesser steak. You’d be surprised how many restaurants do it.
Cast iron pan scorching hot, well seasoned room temp steak, Ghee butter (much higher smoke point than regular butter) with fresh garlic and rosemary, sear each side and let rest in a warm oven. Best steak you can make imo!
