What Cut of Beef Should I Use for This Roast?

The star of this recipe is the beef tenderloin, one of the most tender and prized cuts available. For the best results, choose a center-cut (also known as “Chateaubriand”) as it’s evenly shaped and roasts uniformly. I recommend asking your butcher to trim and tie it for you, or you can do it yourself at home. Make sure the meat is well-marbled and of high quality for optimal tenderness and flavor.

Options for Substitutions

You can get creative with this recipe based on what’s available or your dietary preferences:

• Butter Substitute: Use ghee or olive oil if you’re avoiding dairy. While you won’t get quite the same richness, both options still carry herbs well.
• Herbs: Swap rosemary or thyme for sage or oregano if you prefer different aromatic profiles.
• Garlic: Fresh is best, but garlic powder can be used in a pinch. Use half the amount.
• Meat Cut: If tenderloin is too pricey, try sirloin roast or tri-tip for a more budget-friendly alternative.
• Add Heat: A pinch of crushed red pepper flakes in the butter mix gives a subtle, spicy kick.

Ingredients for this Garlic Herb Butter Beef Tenderloin Roast

• Beef Tenderloin (center-cut, 3 to 4 lbs): This is the main attraction, prized for its tenderness and luxurious flavor. The center-cut ensures even cooking.
• Unsalted Butter (1/2 cup, softened): Acts as the base for the herb mixture, keeping the meat moist while creating a flavorful crust.
• Fresh Garlic (4–5 cloves, minced): Delivers bold, aromatic flavor that deepens as it roasts.
• Fresh Rosemary (1 tablespoon, finely chopped): Offers a fragrant, piney aroma that pairs beautifully with beef.
• Fresh Thyme (1 tablespoon, finely chopped): Adds a subtle, earthy depth that complements the richness of the meat.
• Kosher Salt (2 teaspoons): Essential for seasoning and drawing out the meat’s natural flavor.
• Freshly Ground Black Pepper (1 teaspoon): Adds a touch of sharp heat and balances the butteriness.
• Olive Oil (1 tablespoon): Used to sear the meat and help develop a beautiful crust.
• Kitchen Twine: For tying the roast to ensure even shape and cooking.

Step 1: Prep the Beef Tenderloin

Trim any excess silver skin and fat if your butcher hasn’t already. Tuck the thin end under and tie the roast with kitchen twine at 1-inch intervals to ensure even thickness and roasting.

---

Step 2: Make the Garlic Herb Butter

In a small bowl, mix softened butter, minced garlic, chopped rosemary, thyme, salt, and pepper until well combined. Set aside at room temperature to keep it spreadable.

---

Step 3: Season and Sear the Roast

Pat the tenderloin dry with paper towels. Rub all sides with olive oil. Heat a large oven-safe skillet over medium-high heat and sear the beef for 2-3 minutes on all sides until a deep brown crust forms.

---

Step 4: Apply the Garlic Herb Butter

Remove the skillet from heat. Generously slather the top and sides of the roast with the garlic herb butter. Make sure every surface gets a bit of that flavorful mixture.

---

Step 5: Roast the Beef Tenderloin

Transfer the skillet to a preheated oven at 425°F (218°C). Roast for about 25–35 minutes or until the internal temperature reaches 125°F for medium-rare or 135°F for medium. Use a meat thermometer for accuracy.

---

Step 6: Rest and Slice

Remove the roast from the oven and tent loosely with foil. Let it rest for at least 15 minutes to allow juices to redistribute. Slice into 1-inch thick medallions and serve warm.

How Long to Prepare the Garlic Herb Butter Beef Tenderloin Roast

Prep Time: The preparation for this roast takes about 20–25 minutes. This includes trimming the tenderloin, tying it up, preparing the garlic herb butter, and searing the meat. Having your ingredients prepped ahead of time makes this process smooth and manageable.

Cook Time: Roasting takes approximately 25–35 minutes depending on your desired doneness. I recommend using a meat thermometer to ensure precision. Factor in an additional 15 minutes for resting the roast before slicing to lock in those delicious juices.

Tips for Perfect Garlic Herb Butter Beef Tenderloin Roast

• Use a thermometer: It’s the most reliable way to avoid overcooking such a premium cut of beef.
• Let the meat rest at room temperature before cooking: This ensures even cooking from edge to center.
• Sear before roasting: That golden crust is flavor-packed and locks in moisture.
• Use fresh herbs: The aromatic intensity of rosemary and thyme is much more vibrant fresh than dried.
• Rest after roasting: Always let the roast sit before slicing so the juices stay in the meat, not on your cutting board.

Watch Out for These Mistakes While Cooking

• Overcooking: Tenderloin dries out quickly beyond medium doneness.
• Skipping the sear: You’ll miss out on a beautifully caramelized exterior.
• Using cold butter: It won’t spread properly and won’t coat the meat evenly.
• Not tying the roast: Uneven thickness leads to uneven cooking.
• Cutting too soon: Always rest the meat to avoid a dry roast.
