My Beef Tenderloin Recipe recipe makes the ideal holiday meal because it is juicy, tender, and oh-so-delicious. This is the best beef tenderloin, complete with sea salt, pepper, garlic, and thyme. It has a gorgeous crust and is bursting with flavor in every bite.

What Is a Beef Tenderloin?

The most tender beef cut is the tenderloin, which is found inside the loin. This is where the tenderloin’s pointy end, which is used to make filet mignon, comes from. The tenderloin is a very lean cut because it contains very little fat. Due to all of that, beef tenderloin is one of the most costly beef cuts.

When properly cooked, it will melt in your mouth. And let’s face it, you’ll want to make sure you’re cooking the meat properly if you’re spending a lot of money on it.

How To Prepare Beef Tenderloin

  • TRIM: If your beef tenderloin hasn’t already been prepared for you, begin by trimming it. I purchased mine from Costco and it came trimmed. Remove the “silverskin” that runs down the length of the beef tenderloin in order to trim it. With your other hand, gently pull it up while running your knife underneath. Remove “the chain,” which is merely a fatty strip along the outside, as well as any additional extra fat that may be present around the perimeter.
  • TIE: The beef tenderloin is a long piece of beef with a point at one end. It’s crucial to tie the beef up and shape it as uniformly as you can so that it cooks evenly. Using butcher’s twine you can easily tie it up. Create a uniform cylinder shape by tucking the long pointed end up into the thicker part of the tenderloin.
  • CHILL: You can leave your tenderloin in the refrigerator overnight, unwrapped, to give it a delicious crust on the outside. When seared, this will help the surface become drier and develop a gorgeous browned crust. If you don’t have time for this step, don’t worry; you’ll still get fantastic results.

How To Cook Roast Beef Tenderloin

  • SEASON: Sprinkle salt and pepper on the exterior and allow to rest for a few hours at room temperature. This will help to cook the insides evenly.
  • SEAR: In a large cast-iron skillet, heat a little olive oil over medium-high heat. Sear the beef tenderloin for 3 to 5 minutes per side. I divided the beef tenderloin into two manageable roasts that fit easily into my 12″ skillet because it is a long piece of beef.
  • SLATHER: Make a straightforward garlic-herb butter and smother the seared beef with it. Insert your probe thermometer.
  • ROAST: Cook the beef tenderloin at 425 degrees F. until the desired internal temperature is reached. This will only take about 20 to 25 minutes!.

What Temperature To Cook Beef Tenderloin?

After searing it in a skillet, we roast our beef tenderloin at a high temperature of 425 degrees Fahrenheit. If you don’t yet have an oven-safe skillet, you can sear the beef tenderloin first and then finish cooking it in an oven-safe dish.

The beef tenderloin should be seared on the outside for 12 to 15 minutes (about 3 to 5 minutes per side), then baked for another 20 to 25 minutes for a total cooking time of 40 to 45 minutes. You should allow it to rest after cooking for about 15 minutes so that the internal juices can redistribute and settle while the temperature continues to rise.

What Temperature Should Beef Tenderloin Be?

The worst thing you can do is overcook a pricey cut of beef. Ideally you should cook it to a nice medium-rare or medium. The higher the internal temperature, the more tough the meat will become. My biggest suggestion is to use a digital probe thermometer for accurate cooking.

Here is a good chart to go by.

  • RARE – 115°F – 120°F
  • MEDIUM RARE – 120°F – 125°F
  • MEDIUM – 130°F – 135°F

Remember that after being taken out of the oven, the internal temperature will continue to rise by 5 to 7 degrees.

What To Serve with Beef Tenderloin

  • Creamy Horseradish Sauce
  • Fluffy Mashed Potatoes
  • Parmesan Roasted Brussels Sprouts
  • Fresh green beans and mushrooms can be cooked in the same skillet the beef tenderloin was cooked in until they are tender and delicious.
