Cooked up a 2.5" 3lb. prime bone-in ribeye. (other steak put back in fridge)
Oven at 200 for 85 minutes:
Seared it on medium heat for 1:15 side. Making the blue cheese onion cream sauce again, but adding mushrooms, also making some mashed:
Crisping sides and melting the fat off. Later, some of the left-over rendered fat and butter were added to the cream sauce.
Turned stove up to medium-high and gave it 30 secs a side with pressure added.
Pretty happy considering I had no thermometer:
Plated with mashed, sauce, and on a bed of baby arugula:
