1.5-Inch Filet Mignon (Beef Tenderloin), Medium Well: Pull Temp & Cook Time
A 1.5 inch filet mignon cooked medium well needs about 1h 18m over 250 °F / 120 °C. Pull it at 146 °F / 63 °C; carryover takes it to 150 °F. Rest 7 minutes before slicing.
Every method compared
Same 1.5 inch filet mignon, same doneness — only the heat changes. The leanest premium steak there is. Almost no intramuscular fat means it dries out fast — this is the cut where pulling 5 °F early saves dinner.
| Method | Pit temp | Cook time | Pull at | Rest |
|---|---|---|---|---|
| Reverse Sear | 250 °F / 120 °C | 1h 18m | 146 °F | 7 min |
| Direct Grilling | 450 °F / 230 °C | 26 min | 141 °F | 10 min |
| Sous Vide | 150 °F / 65 °C | 1h 46m | 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 1.5 inch filet mignon be pulled at for medium well?
Pull at 146 °F / 63 °C. Carryover cooking adds about 4 °F while it rests, landing on the 150 °F / 65 °C that defines medium well.
How long does it take?
About 1 hour 18 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 1.5 inch thick, reverse sear wins. Direct heat (26 min) burns the crust long before the centre is ready and leaves a thick grey band. Reverse sear takes 1h 18m but gives edge-to-edge medium well.
How long should it rest?
7 minutes for this thickness. Tent loosely with foil — sealing it tight steams the crust you just built.
