Recipe techniques that work

  • Dry brine: Adding salt and pepper to the roasted tenderloin and letting it sit in the refrigerator overnight adds great flavor and helps create a beautifully browned crust.
  • Slow roasting: low temperature roasting guarantees a uniform internal temperature from edge to edge for a perfectly done medium-rare roast.
  • Finishing with herb butter: Finishing the outside sear with seasoned herb butter further enhances the flavor and color of the crust. This step produces 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.

Tenderloin roast is an amazing holiday roast.

A whole beef tenderloin roast is made up of three distinctive parts

  • Filet mignon steaks are cut from the thick end of the roasted tenderloin.
  • Chateaubriand is the center cut of the tenderloin. This part of the roast is the tastiest but still maintains the prized tenderness of the fillet. When I cook for a smaller group, I ask the butcher to give me the Chateaubriand roast or the center cut of the roasted beef tenderloin.
  • Beef Tips: The end of the beef tenderloin is usually used when you see a recipe for beef tips. This part of the roast cannot be used to cut steak, so it is an economical way to enjoy this tender cut of beef.

How to prepare the beef fillet recipe

  • Put in order: Start by eliminating excess fat. You can also ask your butcher to cut the roast for you.
  • Necktie: Tying the roast with kitchen twine ensures even cooking as it keeps the meat well tied during cooking.
  • Season: Salt and pepper the roast the night before. If desired, you can also add finely ground dried rosemary and garlic powder. But remember that you'll finish this roast with seasoned herbed brown butter.

How to cook roast beef tenderloin

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

High-temperature cooking produces a more well-done roast on the outside. Because roast tenderloin is a leaner cut of meat, this well-done temperature is not optimal for producing the best flavor. In general, leaner cuts of beef should be left rare, with medium-rare being the most recommended.

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

At what temperature should you cook beef fillet?

To slow roast the 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 removed from the oven. This will allow for extra cooking while you develop the outer crust with seasoned butter.

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

It is not necessary to rest the roast before slicing it. Normally a roast like a prime rib might rest for up to an hour before being sliced.

Using a meat thermometer is key. Without a probe thermometer it is not possible to accurately measure the internal temperature.

  • The day before: Prepare the roast by tying it with butcher's twine and seasoning it well with salt and pepper. Place the seasoned roast on a wire rack set over a heavy roasting pan. Place the roast in the refrigerator and let it sit overnight to dry in the brine. [note 3]

  • When you're ready to cook: Place the oven rack in the center position of the oven. Preheat oven to 225℉ (107℃). Place the roast in the oven and cook until the internal temperature reaches 49℃.

  • Rest for 10 minutes: Remove the roast from the oven and set aside to rest for 10 minutes. Remove the butcher's twine and prepare to finish the roast in the pan or under the grill.

  • Prepare the herb butter: Add the butter to a pan and heat over medium heat until the butter is lightly browned. Add the fresh herbs and shallots.

  • To finish in the pan: Add the roast to the pan and use a spoon to spread the butter over the roast. Turn the roast every 30 seconds until you get a well-browned outer crust. It takes about 1 or 2 minutes. The internal temperature should be 125℉ (52℃) for rare meat and 130℉ (54℃) for rare meat.

  • To finish under the grill: Adjust the oven rack so it is 6 inches from the rack. Pour the butter and herb mixture over the top. Place the roast under the grill. Turn the roast every 30 seconds until you get a well-browned outer crust. It takes about 1 or 2 minutes. The internal temperature should be 125℉ (52℃) for rare meat and 130℉ (54℃) for medium rare.

  • Rest: Because this roast is slow roasted at a lower temperature, it does not require significant resting time before slicing.

  • Serve: Serve with horseradish cream sauce, fresh chives and a sprinkling of coarse salt, such as fleur de sel or Maldon salt.

  1. For this recipe I used the center cut. However, this recipe can be made with a whole roasted filet (serves 10 to 12) or with the smaller center-cut chateaubriand (serves 4 to 6). Ask your butcher to carve the roast to save time.
  2. You can vary the fresh herbs used for the herb butter. Browned butter gives the roast a nice color and flavor.
  3. Dry brining overnight serves two purposes. It dries out the outside of the roast to promote better browning and adds flavor through osmotic diffusion.
