How to Make Garlic Butter Beef Tenderloin

Step 1: Prepare the Beef

Remove the beef tenderloin from the refrigerator about 30 to 45 minutes before cooking.

Pat the surface completely dry with paper towels.

If one end of the tenderloin is much thinner than the other, tuck the thin end underneath and tie the roast with kitchen twine at 1 1/2 to 2-inch intervals. This helps the beef cook more evenly.

Step 2: Preheat the Oven

Preheat the oven to 425°F (220°C).

Step 3: Season the Tenderloin

Season the beef generously on all sides with kosher salt and freshly ground black pepper.

Step 4: Make the Garlic Butter

In a small bowl, combine the softened butter, minced garlic, rosemary, thyme, garlic powder, and onion powder.

Mix until evenly combined.

Step 5: Sear the Beef

Heat the olive oil in a large oven-safe skillet over medium-high heat.

When the skillet is hot, add the beef tenderloin.

Sear for about 2 minutes per side, turning until the outside is evenly browned.

Do not cook the center at this stage. The goal is simply to develop a flavorful crust.

Step 6: Add the Garlic Butter

Remove the skillet from the heat.

Spread most of the garlic herb butter over the top and sides of the beef.

Reserve about 1 tablespoon for finishing.

Step 7: Roast the Beef

Transfer the skillet to the preheated oven.

Roast until the beef reaches your preferred internal temperature.

• Rare: Remove at about 120°F to 125°F
• Medium-rare: Remove at about 125°F to 130°F
• Medium: Remove at about 135°F to 140°F

For a 2 1/2 to 3-pound tenderloin, roasting usually takes approximately 20 to 30 minutes, but thickness varies, so an instant-read thermometer is the most reliable guide.

Step 8: Rest the Beef

Transfer the tenderloin to a cutting board.

Loosely tent with foil and let it rest for 10 to 15 minutes.

The internal temperature will continue to rise slightly while resting.

Step 9: Make the Pan Sauce

Place the skillet back over medium heat.

Add the beef broth and Worcestershire sauce.

Use a wooden spoon to scrape up the flavorful browned bits from the bottom of the skillet.

Simmer for about 3 to 4 minutes, or until slightly reduced.

Stir in the remaining tablespoon of garlic butter.

Taste and adjust the seasoning if needed.

Step 10: Slice the Tenderloin

Remove any kitchen twine.

Slice the beef across the grain into approximately 1/2 to 3/4-inch-thick slices.

Step 11: Serve

Arrange the sliced beef on a serving platter or shallow serving dish.

Spoon the warm pan juices over and around the meat.

Serve immediately while the beef is warm and juicy.

Tips for Perfect Beef Tenderloin

• Pat the meat dry: A dry surface browns much better.
• Use a thermometer: Beef tenderloin is expensive, so temperature is more reliable than guessing by time.
• Do not overcook it: Tenderloin is at its best when the center remains juicy.
• Sear before roasting: This creates the rich browned exterior.
• Tie uneven tenderloin: This helps the roast cook evenly from end to end.
• Rest before slicing: Cutting immediately can cause more juices to escape.
• Slice across the grain: This keeps every bite tender.

Understanding Beef Doneness

Because beef tenderloin is thick, internal temperature is the best way to determine doneness.

Remember that the temperature generally rises a few degrees while the roast rests, so remove it from the oven before it reaches the exact final temperature you want.

If serving guests with different preferences, the thinner ends usually cook slightly more than the thick center, providing a natural range of doneness.

Easy Variations

Pepper-Crusted Beef Tenderloin

Increase the freshly cracked black pepper and press it firmly onto the outside of the roast before searing.

Garlic Rosemary Tenderloin

Double the rosemary and add an additional clove of garlic for a stronger herb flavor.

Dijon Herb Tenderloin

Mix 1 tablespoon Dijon mustard into the garlic butter before spreading it over the beef.

Parmesan Herb Crust

Add a small amount of finely grated Parmesan to the garlic butter for a savory crust.

Mushroom Sauce Version

Sauté sliced mushrooms in the skillet after removing the beef, then prepare the pan sauce around them.

What to Serve with Beef Tenderloin

• Garlic mashed potatoes
• Roasted potatoes
• Scalloped potatoes
• Green beans
• Roasted asparagus
• Honey glazed carrots
• Roasted Brussels sprouts
• Creamed spinach
• Fresh dinner rolls
• Simple green salad

Make-Ahead Instructions

The beef can be trimmed, tied, and seasoned several hours before cooking.

Store it covered in the refrigerator and remove it about 30 to 45 minutes before you plan to sear it.

The garlic herb butter can also be prepared up to 3 days ahead and stored covered in the refrigerator.

Allow the butter to soften before spreading it over the beef.

Storage

Refrigerator

Store leftover beef in an airtight container in the refrigerator for up to 3 to 4 days.

Keep any remaining pan juices in a separate covered container or spoon them over the beef before refrigerating.

Freezer

Wrap cooled portions tightly and freeze in a freezer-safe container for up to 2 months.

Thaw overnight in the refrigerator before reheating.

How to Reheat Beef Tenderloin Without Drying It Out

Place the sliced beef in a baking dish with a few tablespoons of beef broth or reserved pan juices.

Cover loosely and warm in a 275°F (135°C) oven until heated through.

Using lower heat helps prevent the tenderloin from becoming overcooked.

Frequently Asked Questions

What cut of beef is best for this recipe?

A center-cut beef tenderloin roast works best because its relatively even thickness helps it cook consistently.

What temperature is best for beef tenderloin?

Many people prefer beef tenderloin medium-rare. For that result, remove it from the oven around 125°F to 130°F and allow it to rest before slicing.

Do I need to sear beef tenderloin first?

Searing is not strictly required, but it significantly improves browning and develops a deeper savory flavor on the exterior.

Why should beef tenderloin rest before slicing?

Resting gives the heat and juices time to redistribute through the meat, helping it stay juicier when sliced.

Can I prepare the tenderloin ahead?

Yes. Trim, tie, and season it several hours ahead, then refrigerate until close to cooking time.

Can I use dried herbs?

Yes. Replace each teaspoon of fresh herbs with approximately 1/3 teaspoon dried herbs.

Can I cook the beef entirely in the oven?

Yes, but searing first gives better browning. If skipping the stovetop step, roast until the desired internal temperature is reached.

How thick should I slice beef tenderloin?

For serving as a main course, slices about 1/2 to 3/4 inch thick work especially well.

What can I do with leftovers?

Leftover tenderloin works well in steak sandwiches, salads, wraps, breakfast hash, or served cold with horseradish sauce.
