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.
HOW TO ROAST BEEF TENDERLOIN
HOW TO ROAST BEEF TENDERLOINThis 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!

I made this last night for Christmas Eve. It’s the first time I’ve done a whole tenderloin and I have to say it was the bomb diggity. Everyone enjoyed it. Thanks for posting this.
That’s wonderful! I’m very happy you loved it! Thank YOU! 🙂
What about a 8lb tenderloin?
Double all the other ingredients, too, and just have that thermometer handy so you can check on the meat until internal temperature reaches 130˚F.
You put it in the oven uncovered?
I didn’t notice in the comments but to acquire medium rare consistency for two 3 1/2 pound tenderloins is the oven time still 25-30 minutes total? Appreciate your reply ☺️
When I’m getting this ready to tie should I cut off the narrow end or fold it up to make it thicker?
If there’s a narrow end, tuck it under and try to secure it with the twine.
Too hot. Even after resting for a full hour, it took a long time to reach the right temp and by then the outside was almost burnt, and that was with a 2.5 lb roast. I prefer another recipe where cook the tenderloin low and slow. The spice rub is great though!
I’m very sorry this recipe didn’t work out for you. If you could please just clarify for me so that I can help troubleshoot because, this is a recipe I have cooked over and over again many, many times, and have never had this issue. Are you saying that a 2.5 pound roast cooked for an hour at 450˚F? And, it wasn’t cooked through?
Smells great while cooking
I didn’t have kitchen twine and all I could dig up was common thread
Hope it works.Next time I won’t be so spontaneous
Sounds great! Trying this today. Can you use dried Rosemary?
Hi!
Yes, you can use about 1 teaspoon dried rosemary for every 1 tablespoon fresh rosemary.
Do you use an au jous to dip into?
Hi!
You absolutely can. I have a recipe for au jus prepared with the drippings of the meat. This is a recipe for prime rib, but the au jus recipe is also there: https://diethood.com/prime-rib-recipe/
how long would you cook a 6 lb tenderloin?
I have a 5.5 pound tenderloin can it be cut in half so it will fit in my skillet?
Yes, that should work. 🙂
what is the purpose of tying it if it isn’t filleted open?
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?
Hi!
Yes, that will totally work. 🙂
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.
Hi! 👋
Cast iron dutch oven will work, and yep, it should be cooked uncovered.
What a delicious dinner idea! It looks so tender. My husband would be head over heals for this.

I didn’t realize that I should let the meat sit for awhile until it gets to room temperature! Thank you for the tip!
