I totally agree with the high sear then low temp approach, I'm cooking one for dinner. The recipe below will deliver a roast that is pink from the center to the outside, yummy!
Beef Tenderloin (serves 5-6)
2-3 pound beef tenderloin, room temperature
Clove of garlic
Black pepper
Preheat oven to 500 degrees.
Rub tenderloin with split garlic clove and season with black pepper. Do not salt as it will draw out juices.
Place tenderloin in oven and immediately lower temperature to 225 degrees.
Using a meat thermometer, check temperature after 30 minutes and then check every 10-15 minutes until temperature reaches 140 degrees for rare. Allow to rest for 10 minutes before slicing
