Serious Eats / J. Kenji López-Alt

For 1 1/2–Inch Steaks in a 250°F (120°C) Oven
Doneness	Target Temperature in the Oven	Final Target Temperature	Approximate Time in Oven
Medium-Rare	120°F (48°C)	130°F (54°C)	25 to 30 minutes
Medium	125°F (52°C)	140°F (60°C)	30 to 35 minutes

updated: season with 0.7% salt by weight (leave steaks to absorb and come to room temp)

120C oven / internal temp target 50C (takes about 15 min from room temp)

oil the steaks on both sides and sear on cast iron pan.  set aside to rest before slicing

58C final internal temp was just right
