How To Make the Garlic Herb Butter Beef Tenderloin Roast

Step 1: Prep the Herb Butter

In a small mixing bowl, combine softened unsalted butter with minced garlic, chopped rosemary, thyme, kosher salt, and black pepper. Mix until well blended and fragrant.

Step 2: Trim and Tie the Roast

Using a sharp knife, trim excess fat and silver skin from the tenderloin. Tie the roast with kitchen twine at 1-inch intervals to ensure even cooking.

Step 3: Sear the Tenderloin

Preheat your oven to 425°F. Heat olive oil in a cast iron skillet over medium-high heat. Sear the tenderloin on all sides until browned, about 2–3 minutes per side.

Step 4: Apply the Herb Butter

Remove skillet from heat and slather the garlic herb butter all over the roast, using a spatula or spoon to coat evenly.

Step 5: Roast to Perfection

Transfer skillet to the oven. Roast until internal temperature reaches 135°F for medium-rare, about 25–30 minutes depending on thickness.

Step 6: Rest and Slice

Remove from oven and let the roast rest for at least 15 minutes. This allows the juices to redistribute. Slice and serve warm.

Frequently Asked Questions

How do I know when beef tenderloin is done?

Use a meat thermometer. For medium-rare, pull at 135°F and rest. For medium, go up to 145°F.

Can I prepare this ahead of time?

Yes! You can prep the herb butter and trim the tenderloin the day before. Just sear and roast when you’re ready to cook.

What if I don’t have fresh herbs?

You can use dried herbs in a pinch, but reduce the quantity by half since dried herbs are more concentrated.

Can I freeze leftovers?

Yes, slice and wrap in foil, then place in a freezer bag. Use within 2 months for best quality.
