Ingredients
Scale
Beef Tenderloin
- 4 to 5 lb. beef tenderloin (trimmed, cut into two pieces and tied)
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp avocado oil
Herb Butter Mixture
- 4 tbsp butter (salted, softened)
- 2 tsp garlic (minced)
- 1 tsp horseradish (prepared or Dijon mustard)
- 1 tsp rosemary (minced) or thyme
Instructions
- Prepare the Herb Butter: In a small bowl, combine the softened butter, minced garlic, horseradish (or Dijon mustard), and minced rosemary or thyme. Mix well until all ingredients are fully incorporated. Set aside.
- Season the Tenderloin: Pat the beef tenderloin pieces dry with paper towels. Season evenly on all sides with salt and black pepper.
- Sear the Tenderloin: Heat the avocado oil in a large oven-safe skillet or pan over medium-high heat. Once hot, place the tenderloin pieces in the pan and sear each side for about 2-3 minutes until a golden-brown crust forms. This will lock in the juices and add rich flavor.
- Apply Herb Butter: Remove the pan from heat. Spread the prepared herb butter mixture evenly over the seared tenderloin pieces, covering all surfaces.
- Roast the Beef: Preheat your oven to 375°F (190°C). Transfer the skillet with the butter-coated tenderloin to the oven. Roast for approximately 30-40 minutes, or until the internal temperature reaches your desired doneness (125°F for rare, 135°F for medium-rare).
- Rest the Meat: Remove the tenderloin from the oven and transfer to a cutting board. Tent loosely with foil and let rest for 10-15 minutes to allow the juices to redistribute throughout the meat.
- Slice and Serve: After resting, slice the beef tenderloin into thick slices. Serve immediately, optionally garnished with fresh herbs or accompanied by your favorite sides.
Notes
- This beef tenderloin is first seared on the stovetop to create a flavorful crust, then roasted in the oven to perfection.
- Resting the meat after roasting ensures juicy, tender slices.
- You can substitute Dijon mustard for prepared horseradish according to your preference.
- Using avocado oil helps achieve a good sear due to its high smoke point.
- For herb variation, thyme can replace rosemary as preferred.
