Roast Beef Tenderloin (Reverse Sear)

The Roast Beef Tenderloin uses the reverse sear technique, starting with a low oven temperature of 225°F to gently bring the internal temperature to 120°F, producing even cooking and retained moisture. The roast is trimmed and tied, then rubbed with olive oil and a seasoning mix of black pepper, fresh rosemary, thyme, kosher salt, and brown sugar, creating a balanced seasoning that enhances the natural beef flavor.

After its initial slow roast, the beef rests briefly before increasing the oven temperature to 450°F to sear the exterior, forming a savory crust and achieving the final internal temperature of 125-130°F for medium-rare doneness. A final rest period settles the juices for a moist interior when sliced.

The recipe emphasizes using a meat thermometer for precision, advises letting the meat come to room temperature before cooking, and drying it to promote a good sear. Doneness targets are clearly described, helping achieve the preferred center color and texture.

A meat thermometer is crucial for precisely cooking the beef to desired doneness.Bring the tenderloin to room temperature and dry it before seasoning to improve cooking results.Salt is applied just before cooking to enhance flavor and crust development.Rest the meat after each cooking stage to allow juices to redistribute.Doneness target temperatures: Rare 120-125°F, Medium Rare 130-135°F, Medium 140-145°F, Medium Well 150-155°F, Well Done 160°F.
