WHAT IS BEEF TENDERLOIN?

Beef Tenderloin is the most tender cut of beef. It’s cut from the loin of a cow, and when cut into steaks, it is what we know as “filet mignon”.  There is not a lot of fat in the tenderloin, which makes it a lean cut of meat. When cooked properly tenderloin will literally melt in your mouth!

HOW TO PREPARE BEEF TENDERLOIN

There are a few steps to preparing beef tenderloin, but don’t worry – they are easy!

  • Bring to room temperature: Before roasting, I highly advise to take the tenderloin out of the fridge at least one hour and up to two hours before cooking. There’s no marinating required with this recipe, but letting the meat come to room temperature will produce juicier and evenly cooked meat.
  • Dry & trim: Pat your tenderloin dry with paper towel. Then remove the “silverskin” that runs down the length of the tenderloin by running a sharp knife underneath it and gently pulling the it off. You can also trim any excess fat on the meat.
  • Oil and season: Grab some olive oil and just rub it all around the meat. GENEROUSLY season with salt and fresh ground pepper. In a small bowl mash together minced garlic with a couple tablespoons of fresh chopped rosemary leaves. Rub the tenderloin with the prepared garlic mixture.
  • Tie with twine: This is an important step – don’t skip it! Place the tenderloin over pieces of precut kitchen twine spaced one-inch apart and tie them closed. You can also ask the butcher to tie it for you (trim it, too!) when buying the tenderloin.

This is a two-step process; first, you want to sear the meat over medium-high heat, and then pop it in the oven to finish the cooking process. In this way, the tenderloin will have a nicely browned exterior and a perfectly pink interior.

  • Heat the oil: Heat a tablespoon of vegetable oil in a cast iron skillet.
  • Sear: Add the tenderloin to the hot oil and sear on all sides until browned.
  • Roast: Transfer skillet to a 450˚F-degree oven and continue to cook for 25 minutes, or until internal temperature reaches 125˚F to 130˚F. Do not overcook because that will result in chewy and dry beef. Use a meat thermometer to check for doneness. 
  • Allow to rest: Remove from oven, tent a piece of foil over the tenderloin and let rest for 10 to 15 minutes before cutting. 

HOW LONG TO COOK BEEF TENDERLOIN?

Searing the tenderloin usually takes about 4-5 minutes per side, which amounts to about 12-15 minutes total for searing. Roasting the tenderloin then takes about 25 minutes.

Total cooking time for beef tenderloin for searing and roasting is therefore about 40 minutes. You’ll also want to let your tenderloin rest for 10-15 minutes, which allows all the juices to settle. Resting time helps make your tenderloin incredibly tender and juicy!

      Meat will expand while cooking and tying it up keeps it from spreading out. This will result in even cooking because most roasts are thick in the middle and thinner at the ends.

    i don’t have a cast iron skillet or dutch oven. can this be browned on a regular pan and then transferred to a roasting pan? will it still have the same flavor and cook time?

  2. barbara

    Can you put in a cast iron dutch oven or is it better prepared in a cast iron skillet? Also it does not get covered when in the oven…correct? Thanks so much.
