Ingredients

4 to 5 lb beef tenderloin, trimmed, cut into two pieces, and tied
1 tsp salt
½ tsp black pepper
2 tbsp olive oil
4 tbsp salted butter, softened
2 tsp garlic, minced
1 tsp prepared horseradish or Dijon mustard
1 tsp minced rosemary or thyme

Instructions

Step 1: Prep the Beef Tenderloin
Start by tying the trimmed beef tenderloin with butcher’s twine. This will help the roast maintain an even shape during the cooking process, ensuring a uniform cook. Generously season the beef with salt and black pepper, making sure it’s coated on all sides. Once seasoned, let the tenderloin rest at room temperature for about 2 hours. This step is essential because it allows the meat to cook evenly, and it will make the final roast more tender and juicy.

Step 2: Preheat the Oven
While the tenderloin is resting, preheat your oven to 425°F (220°C). This temperature will give you a beautifully roasted beef tenderloin with a perfectly crisp, caramelized exterior while keeping the interior juicy and tender.

Step 3: Sear the Tenderloin
Heat the olive oil in a large cast-iron skillet over medium-high heat. Once the oil is hot and shimmering, add the beef tenderloin. Sear the meat on all sides for about 3 to 5 minutes per side until a golden-brown crust forms. This step is crucial because the crust helps lock in the juices and gives the roast its signature, flavorful exterior. Don’t skip this step!

Step 4: Make the Herb Butter Mixture
While the tenderloin is searing, take a small bowl and combine the softened butter, minced garlic, horseradish (or Dijon mustard), and minced rosemary or thyme. Mix the ingredients well until you have a smooth, aromatic butter mixture that will be spread over the beef after searing.

Step 5: Coat with Herb Butter
Once the tenderloin is seared, spread the prepared herb butter mixture evenly over the top of the beef. Be generous with the butter, making sure it covers the meat completely. This not only adds incredible flavor but also helps keep the roast moist as it cooks.

Step 6: Roast in the Oven
Now, insert a probe thermometer into the thickest part of the tenderloin to monitor the internal temperature. Place the skillet with the tenderloin directly into the oven. If you’re using a skillet that’s not oven-safe, carefully transfer the meat to a baking dish. Roast the tenderloin for about 20 to 25 minutes, or until the thermometer reaches your desired internal temperature. For medium-rare, aim for 125°F to 130°F; for medium, 135°F to 140°F; and for well-done, 145°F.

Step 7: Rest and Serve
Once the roast has reached the desired internal temperature, remove it from the oven and let it rest for at least 10 minutes. This resting period allows the juices to redistribute throughout the meat, making it more tender and flavorful when sliced. After resting, slice the tenderloin into 1-inch thick slices and serve.

Additional Tips

Rest the Meat: Always let the tenderloin rest for at least 10 minutes before slicing to ensure it remains juicy.
Use a Probe Thermometer: To avoid overcooking, a meat thermometer is a game changer. It ensures the beef is cooked to your exact preference.
Be Generous with Seasoning: Don’t be shy with the salt and pepper. The seasoning will enhance the natural flavor of the beef.
Use Fresh Herbs: For the best flavor, use fresh rosemary or thyme. The freshness of the herbs elevates the entire dish.
Don’t Skip the Searing: Searing the beef creates a beautiful crust that locks in the juices, so it’s a vital step.

Recipe Variations

Herb Variations: Instead of rosemary or thyme, you could try sage, parsley, or a mix of Italian herbs for a different flavor profile.
Horseradish Alternative: For a tangy kick, swap the horseradish for Dijon mustard, or even use a bit of balsamic vinegar in the butter mixture for a different depth of flavor.
Add Blue Cheese: If you’re a fan of blue cheese, consider adding a sprinkle on top of the roast before serving for an extra layer of richness.

Serving Suggestions

Pair with a bold red wine, such as Cabernet Sauvignon or Merlot, to complement the richness of the beef.
Serve with creamy mashed potatoes, garlic green beans, and roasted carrots for a complete meal.
Make it the centerpiece of a festive holiday table for a special occasion.

Freezing and Storage

Freezing: While beef tenderloin is best enjoyed fresh, you can freeze leftovers. Wrap the leftover beef tightly in plastic wrap and aluminum foil, then place in an airtight container or freezer bag. It will last in the freezer for up to 3 months. When ready to reheat, thaw overnight in the fridge and reheat gently in the oven or a skillet.
Storage: Leftover beef can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven or on the stove to avoid drying out the meat.
