Works best with whole cuts
But certainly can be done with thick individual steaks. With a whole tenderloin for example, you can get it to 115-120 then tent with foil for up to 45 minutes I think (check the food lab on serious eats). You're gonna want to season and leave uncovered in the fridge for a day minimum to let some moisture out of the meat. Slowly bring it up to temp, rest, then sear it to get the mailard reaction on the surface. Make a good wine reduction (I use the gristle chunks, Cabernet, beef broth, a little lemon and whatever aromatics are on hand) and you're good to go.
