Ingredients for Beef Tenderloin Roast

For the Beef:

• 1 center-cut beef tenderloin roast (4 to 4½ pounds), trimmed and tied – Ask your butcher to do this
• 2 teaspoons kosher salt – For the perfect seasoning
• 1 teaspoon freshly ground black pepper – Fresh is best
• 2 tablespoons avocado oil – High smoke point for searing; olive oil works too

For the Garlic Herb Butter:

• 6 tablespoons unsalted butter, softened – Must be room temperature
• 6 garlic cloves, minced – Fresh garlic is essential
• 1 teaspoon finely chopped fresh rosemary – Don’t use dried
• 1 teaspoon finely chopped fresh thyme – Fresh herbs make all the difference

For Serving:

• Horseradish sauce – Homemade or store-bought
• Fresh herbs for garnish – Rosemary or thyme sprigs
• Flaky sea salt (optional) – For finishing

Equipment Needed:

• Large oven-safe skillet or cast-iron pan (12-inch)
• Kitchen twine (butcher’s string)
• Meat thermometer (instant-read or probe)
• Paper towels
• Cutting board
• Sharp carving knife

Important Shopping Tip: Ask your butcher to trim the silverskin and tie the roast for you. This saves time and ensures the best results. A tied roast cooks more evenly!

How to Cook Beef Tenderloin Roast

Step 1: Bring to Room Temperature

Remove the beef tenderloin from the refrigerator 1 to 2 hours before cooking. This allows it to come to room temperature, which ensures even cooking throughout.

Place it on a plate or cutting board and loosely cover with plastic wrap. Don’t skip this step—cold meat straight from the fridge won’t cook evenly, resulting in an overcooked exterior and undercooked center.

Timing tip: Take the tenderloin out when you start prepping your side dishes and appetizers. By the time you’re ready to cook, it’ll be at the perfect temperature.

Step 2: Prepare the Garlic Herb Butter

While the beef comes to temperature, make your compound butter. In a small bowl, combine the softened butter, minced garlic, chopped rosemary, and chopped thyme.

Mix thoroughly with a fork or small spatula until all the herbs and garlic are evenly distributed throughout the butter. The butter should be soft enough to spread easily—if it’s too firm, let it sit at room temperature a bit longer.

Set this aside while you prepare the beef. The flavors will meld together beautifully as it sits.

Prep-ahead tip: You can make this garlic herb butter up to 3 days ahead and store it covered in the refrigerator. Just bring it back to room temperature before using.

Step 3: Trim and Tie the Tenderloin

If your butcher hasn’t already done so, you’ll need to trim and tie your tenderloin. Remove any visible silverskin (the thin, silvery membrane) by sliding a sharp knife under it and cutting it away.

Because tenderloin is naturally tapered (thicker on one end than the other), tuck the thin tail end underneath itself to create a more uniform thickness. This ensures even cooking.

If your tenderloin is very long, cut it in half so it fits in your skillet. Tie the roast at 2-inch intervals with kitchen twine to help it maintain an even shape during cooking.

Don’t stress: If tying meat intimidates you, ask your butcher to do this when you purchase it. Most are happy to help!

Step 4: Season the Beef

Preheat your oven to 425°F (220°C) while you prepare the meat.

Use paper towels to thoroughly pat the entire surface of the beef tenderloin dry. This is crucial—moisture prevents proper browning and crust formation.

Season both sides generously with the kosher salt and freshly ground black pepper, pressing gently so the seasonings adhere to the meat. Don’t be shy with the seasoning—this large piece of meat needs sufficient salt to bring out its natural flavors.

Pro tip: For even better results, you can season the beef up to 24 hours ahead. The salt will penetrate deeper, creating more flavorful meat throughout.

Step 5: Sear for a Golden Crust

Heat your avocado oil in a large cast-iron skillet or oven-safe pan over medium-high heat. The oil should shimmer and move easily across the pan—this means it’s hot enough.

Carefully place the seasoned beef tenderloin in the hot pan. You should hear an immediate sizzle—if you don’t, the pan isn’t hot enough.

Sear the tenderloin for 2-3 minutes per side, rotating to brown all sides evenly. This should take about 10 minutes total. You’re looking for a deep, golden-brown crust all around.

Safety note: Use tongs to rotate the meat, and be careful of splattering oil. The goal is a beautiful crust, not burnt meat, so adjust heat if needed.

Step 6: Add the Herb Butter and Roast

Once your tenderloin is beautifully seared on all sides, remove the pan from heat. Using a spoon or spatula, generously slather the garlic herb butter mixture all over the top surface of the beef.

Don’t worry about the bottom—the seared crust there is perfect. Focus on coating the top and sides with that delicious herb butter.

If using a probe thermometer, insert it into the thickest part of the roast now, making sure it doesn’t touch bone (there isn’t any) and is centered in the meat.

Transfer the entire skillet to your preheated 425°F oven. Roast for 15 to 20 minutes, depending on your desired level of doneness. Use the temperature guide below to determine when to remove it.

Temperature is key: Don’t rely on time alone—ovens vary. Use a meat thermometer for perfect results every single time.

Step 7: Check the Temperature

For perfect beef tenderloin, you need to understand internal temperatures. Remember that the meat will continue cooking (called carryover cooking) after you remove it from the oven.

Remove from oven at these temperatures:

• Rare: Remove at 110°F (final temp after resting: 115-118°F)
• Medium-Rare: Remove at 120°F (final temp after resting: 125-128°F) ← Recommended
• Medium: Remove at 130°F (final temp after resting: 135-138°F)

For beef tenderloin, medium-rare to medium provides the best texture and flavor. Rare can be too soft, and anything past medium becomes tough.

Insert your instant-read thermometer into the thickest part of the roast. When it reaches your target temperature, immediately remove the skillet from the oven.

Step 8: Rest Before Slicing (Critical!)

Transfer the beef tenderloin to a cutting board (preferably one with a juice groove to catch any drippings). Tent it loosely with aluminum foil.

Let it rest for 10 to 15 minutes—this is absolutely essential! During this time, the juices that were driven to the center by heat will slowly redistribute throughout the meat.

If you cut into it immediately, all those precious juices will run out onto the cutting board, leaving you with drier meat. Patience here pays off enormously.

What to do while waiting: Prepare your serving platter, make your horseradish sauce, or put finishing touches on your side dishes.

Step 9: Slice and Serve

After resting, use kitchen shears or a knife to carefully snip and remove all the kitchen twine from the roast.

Using a sharp carving knife, slice the beef tenderloin into 1-inch thick medallions. You should see that beautiful rosy-pink center surrounded by the golden herb crust.

Arrange the slices on a serving platter, garnish with fresh herb sprigs, and serve immediately with horseradish sauce on the side.

Serving tip: Any accumulated juices on the cutting board are liquid gold—drizzle them over the sliced meat for extra flavor.

Expert Tips for Success

Invest in a Good Thermometer A reliable meat thermometer is non-negotiable for beef tenderloin. This expensive cut deserves precision, and guessing leads to disappointment.

Don’t Skip the Resting Period I know it’s tempting, but cutting immediately ruins the texture. Those 10-15 minutes make the difference between good and exceptional beef.

Room Temperature is Essential Cold meat doesn’t cook evenly. Plan ahead and remove it from the fridge 1-2 hours before cooking—this simple step improves results dramatically.

Pat It Dry Moisture is the enemy of a good crust. Thoroughly dry the surface with paper towels before seasoning and searing.

Use Fresh Herbs Dried herbs won’t provide the same aromatic, flavorful crust. Fresh rosemary and thyme are worth seeking out for this special dish.

Tie It Up Even if your tenderloin seems relatively uniform, tying it ensures even cooking. The twine holds everything together as it roasts.

High Heat for Searing Your pan should be very hot before adding the meat. This creates that coveted golden-brown crust quickly without overcooking the interior.

Butter Must Be Soft Room temperature butter spreads easily and adheres to the meat. Cold butter will just slide off and won’t create that beautiful herb crust.

Storage and Leftovers

Storing Cooked Beef Tenderloin

Let leftover beef tenderloin cool to room temperature (within 2 hours of cooking). Slice it into portions for easier storage and reheating.

Store in an airtight container in the refrigerator for up to 4-5 days. For best results, keep slices whole rather than chopping them up.

Pro tip: Save any pan drippings and store separately. Use them to add moisture when reheating.

Freezing Instructions

Beef tenderloin freezes reasonably well, though texture may soften slightly upon thawing.

Wrap individual slices tightly in plastic wrap, then place in a freezer-safe bag with all air removed. Freeze for up to 3 months.

To thaw, transfer to the refrigerator 24 hours before you plan to use it.

Reheating Tips

Microwave (Quick): Place slices on a microwave-safe plate, cover loosely, and heat on 50% power for 1-2 minutes. Be careful not to overcook.

Oven (Best for Multiple Servings): Place slices in a baking dish with a splash of beef broth, cover with foil, and reheat at 250°F for 10-15 minutes until just warmed through.

Serve Cold: Leftover beef tenderloin is excellent served cold on sandwiches or salads!

Using Leftovers Creatively

• Beef Tenderloin Sandwiches: Slice thin and serve on crusty bread with horseradish sauce
• Steak Salad: Top mixed greens with sliced beef, blue cheese, and balsamic
• Beef and Eggs: Serve alongside eggs for a luxurious breakfast
• Philly Cheesesteak Style: Sauté with peppers and onions, top with cheese

Frequently Asked Questions

How much beef tenderloin per person? Plan for 6-8 ounces of raw meat per person. A 4-pound tenderloin serves 8-10 people. Remember that beef tenderloin is very rich, so people typically eat less than with other cuts.

Do I need to trim the beef myself? While you can trim it yourself, it’s much easier to ask your butcher to trim and tie it for you. Most butchers are happy to do this at no extra charge.

What if I don’t have a cast-iron pan? Any large, oven-safe skillet works. Stainless steel is great. Just avoid non-stick pans in the oven at high temperatures.

Why is my beef tenderloin tough? Beef tenderloin is only tough when overcooked (beyond medium). Use a thermometer and remove it from the oven at the correct temperature to avoid this.

Can I use dried herbs instead of fresh? Fresh herbs are strongly recommended for this recipe. Dried herbs won’t create the same aromatic crust and can taste dusty.

How do I know when it’s done without a thermometer? You really need a thermometer for beef tenderloin. It’s too expensive to risk guessing. However, the touch test (comparing firmness to parts of your hand) can help in a pinch.

Can I cook a frozen beef tenderloin? No, always thaw beef tenderloin completely in the refrigerator (24-48 hours) before cooking. Cooking from frozen will result in uneven cooking.

What’s the difference between beef tenderloin and filet mignon? Filet mignon is cut from the beef tenderloin—specifically the thick center section. When you buy a whole tenderloin, you’re getting the entire muscle that filet mignon steaks come from.
