Whether you’re a seasoned chef or a passionate home cook, our step-by-step instructions and tips and tricks will ensure you can craft an exceptional beef tenderloin roast with resounding success.

recipe Techniques That Work

  • Dry brining: Adding salt and pepper to the tenderloin roast and letting it sit in the fridge overnight adds impressive flavor and contributes to a beautifully browned crust.
  • Slow roasting: Roasting at a low temperature ensures an even edge-to-edge internal temperature for a perfectly done medium rare roast.
  • Finishing in herb butter: Finishing the outer sear with seasoned herb butter further enhances the flavor and color of the crust. This step yields the most beautiful presentation.

What Is a Beef Tenderloin?

Beef tenderloin, often called “Filet Mignon,” is renowned for its unmatched tenderness and buttery texture. This coveted cut comes from the loin region of the cow, and its lean yet marbled nature makes it a prime choice for a roast that promises melt-in-your-mouth perfection.

The tenderloin roast is an impressive holiday centerpiece roast.

A full beef tenderloin roast is comprised of three distinctive parts

  • Filet mignon steaks are cut from the thick end of the tenderloin roast.
  • Chateaubriand is the center cut of the tenderloin. This part of the roast has the most flavor but still maintains the prized tenderness of the filet. When cooking for a smaller group, I ask the butcher to give me the Chateaubriand roast or the center cut of the beef tenderloin roast.
  • Beef tips: The end portion of the beef tenderloin is usually used when you see a recipe for beef tips. This part of the roast can’t be used for steak cuts, so it is an affordable way to enjoy this tender cut of beef.

How To Prepare Beef Tenderloin Recipe

  • Trim: Start by trimming off any excess fat. You can also ask your butcher to trim the roast for you.
  • Tie: Tying the roast with kitchen twine ensures even cooking as it keeps the meat tightly bound in shape as it cooks.
  • Season: Salt and pepper the roast the night before. You can also add finely ground dried rosemary and garlic powder if desired. But remember that you will finish this roast with seasoned herb brown butter.

How To Cook Roast Beef Tenderloin

There are many ways to cook a beef tenderloin roast. After much research, I am using J. Kenji Lopez-Alt’s method for slow-roasting this beef tenderloin at a low temperature. This method produces a flavorful and perfectly evenly cooked tenderloin roast.

Roasting at a high temperature yields a roast that is more well done around the outside. Because the tenderloin roast is a leaner cut of meat this well-done temperature is less than optimal for producing the best flavor. In general, leaner cuts of beef should be left rarer, with medium-rare being the most done that is recommended.

A fattier cut, such as a prime-rib, can be cooked to medium-rare or even medium and still have a great flavor and mouthfeel.

What Temperature To Cook Beef Tenderloin?

To slow-roast beef tenderloin, it will be cooked at 225℉ for 2 to 3 hours, depending on its size.

What Temperature Should Beef Tenderloin Be?

The internal temperature of this beef tenderloin roast should be 120℉ (49℃) when it is removed from the oven. This will allow for a little extra cooking as you develop the outer crust with seasoned butter.

After searing the roast, either under the broiler or in a skillet the internal temperature will rise to 125℉ (52℃) for rare and 130℉ (54℃) for medium rare.

There is no need to rest this roast before slicing. Normally a roast like a prime rib might rest for up to an hour before slicing.

Using a meat thermometer is crucial. Without a probe thermometer you cannot accurately measure the internal temperature.

  • fresh thyme
  • fresh rosemary
  • shallot
  • garlic

For Serving


  • The day before: Prepare the roast by tying it with butcher's string and seasoning it well with salt and pepper. Place the seasoned roast on a wire rack set over a heavy baking sheet. Place the roast into the fridge and let it sit overnight to dry brine. [note 3]
  • When you're ready to cook: Place the oven rack in the center position of the oven. Preheat the oven to 225℉ (107℃). Place the roast in the oven and cook until the internal temperature reaches 120℉ (49℃).
  • Rest for 10 minutes: Remove the roast from the oven and set it aside to rest for 10 minutes. Remove the butcher's twine and get ready to finish the roast in a skillet or under the broiler.
  • Prepare the herb butter: Add the butter to a skillet and heat over medium heat until the butter is lightly browned. Add the fresh herbs and the shallots.
  • To finish in the skillet: Add the roast to the skillet, and use a spoon to distribute the butter over the roast. Turn the roast every 30 seconds until you have a nicely browned outer crust. It takes about 1 to 2 minutes. The internal temperature should be 125℉ (52℃) for rare and 130℉ (54℃) for medium rare.
  • To finish under the broiler: Adjust the oven rack to sit 6 inches from the broiler. Pour over the butter and herb mixture. Place the roast under the broiler. Turn the roast every 30 seconds until you have a nicely browned outer crust. It takes about 1 to 2 minutes. The internal temperature should be 125℉ (52℃) for rare and 130℉ (54℃) for medium rare.
  • Resting: Because this roast is slow-roasted at a lower temperature, it does not need to have s significant resting time before slicing.
  • Serve: Serve with Horseradish Cream Sauce, fresh chives and a sprinkle of coarse salt, such as fleur de sel or Maldon salt.

Laura’s Tips + Notes

  1. I used the center cut for this recipe. However, this recipe can be made with a whole tenderloin roast (serves 10 to 12) or the smaller center-cut chateaubriand (serves 4 to 6). Ask your butcher to trim the roast to save time. 
  2. You can vary the fresh herbs that are used for the herb butter. The browned butter gives the roast a beautiful color and flavor. 
  3. The overnight dry brining serves two purposes. It dries out the outside of the roast to encourage better browning and adds flavor through osmotic diffusion.
