I am doing some 1 1/2" thick bone in wagyu ribeye steaks. They have been dry brining in the fridge since early yesterday. I use the reverse sear method on thick cuts. Normally I do them in the oven in the kitchen on a shallow pan with a roasting rack at anywhere from 200 - 250 degrees. I prefer the lower end. I pull them at about 115 for medium rare then tent with foil. I have a cast iron grill that lays over two burners. I pour on some grape seed oil and turn both gas burners on high. I prefer the flat side of the cast iron.
When it begins to smoke its go time. I have butter slices ready. I can get 3 on the grill at once high heat sear around 45 seconds a side. I melt butter over top while I do this. Then gather all three up on top of each other with my tongs turn and brown the sides. If I have more than three I just have more ready to sear and repeat. Its best to have a pretty robust exhaust fan over your stove if you do it inside.
The weather is supposed to be nice tomorrow so I might do this outside. Use indirect heat to bring them up to temp then slap them on the direct heat. I got some split hickory if I want to use that as a heat source.
