1.25-Inch T-Bone / Porterhouse Steak, Medium Well: Pull Temp & Cook Time
A 1.25 inch t-bone cooked medium well needs about 1h 5m over 250 °F / 120 °C. Pull it at 147 °F / 63 °C; carryover takes it to 150 °F. Rest 6 minutes before slicing.
Every method compared
Same 1.25 inch t-bone, same doneness — only the heat changes. Two steaks on one bone: strip on one side, tenderloin on the other. The tenderloin cooks faster, so keep it angled away from the hottest coals.
| Method | Pit temp | Cook time | Pull at | Rest |
|---|---|---|---|---|
| Reverse Sear | 250 °F / 120 °C | 1h 5m | 147 °F | 6 min |
| Direct Grilling | 450 °F / 230 °C | 19 min | 142 °F | 8 min |
| Sous Vide | 150 °F / 65 °C | 1h 24m | 150 °F | 0 min |
Pull temps differ per method on purpose: a 450 °F grill drives far more residual heat into the meat than a 225 °F pit, so the same final temperature needs a different pull point.

Frequently Asked Questions
What temperature should a 1.25 inch t-bone be pulled at for medium well?
Pull at 147 °F / 63 °C. Carryover cooking adds about 3 °F while it rests, landing on the 150 °F / 65 °C that defines medium well.
How long does it take?
About 1 hour 5 minutes using reverse sear at 250 °F. Times assume the meat starts fridge-cold and the lid stays closed.
Direct grilling or reverse sear at this thickness?
At 1.25 inch thick, direct grilling is the better call — 19 min versus 1h 5m, with a great crust and only a thin grey band. Reverse sear starts paying off above about 1.5 inches.
How long should it rest?
6 minutes for this thickness. Tent loosely with foil — sealing it tight steams the crust you just built.
