Step 1: Prepare the Herb Butter
- Combine Ingredients: In a small bowl, mix together the softened butter, minced garlic, chopped rosemary, thyme, parsley, Dijon mustard (if using), salt, and pepper until well blended.
- Set Aside: Set the herb butter aside to allow the flavors to meld while you prepare the beef.
Step 2: Prepare the Beef Tenderloin
- Preheat the Oven: Preheat your oven to 425°F (220°C).
- Season the Beef: Pat the beef tenderloin dry with paper towels, then season generously with salt and black pepper.
- Sear the Beef: In a large oven-safe skillet, heat the olive oil over medium-high heat. Add the beef tenderloin and sear on all sides until browned, about 2-3 minutes per side. This locks in the juices and enhances the flavor.
Step 3: Apply the Herb Butter
- Coat with Herb Butter: Remove the skillet from the heat. Spread the prepared herb butter all over the top and sides of the beef tenderloin, making sure to coat it evenly.
- Position the Beef: Place the tenderloin on a roasting rack in the skillet or a roasting pan to allow for even cooking.
Step 4: Roast the Beef Tenderloin
- Transfer to the Oven: Place the skillet or pan in the preheated oven and roast for about 20-25 minutes for medium-rare, or until the internal temperature reaches 130°F (54°C).
- Check the Temperature: Use a meat thermometer to check the doneness. For medium, aim for 140°F (60°C); for medium-well, 150°F (65°C).
Step 5: Rest and Slice
- Rest the Beef: Remove the tenderloin from the oven and transfer it to a cutting board. Tent with foil and let it rest for 10-15 minutes to retain its juices.
- Slice and Serve: Once rested, slice the beef tenderloin into 1/2-inch thick slices and serve immediately.
Tips for Perfect Herb Butter Beef Tenderloin Roast
- Resting Time: Resting the meat is crucial for juicy, tender slices. Don’t skip this step!
- Make Ahead: You can prepare the herb butter a day in advance to save time.
- Temperature Control: Using a meat thermometer ensures accurate doneness. Remember, beef will continue to cook slightly after it’s removed from the oven, so account for this when checking temperature.
