| Ingredient | Amount | Notes |
|---|---|---|
| Beef Tenderloin 🥩 | 3 lb | Center-cut, trimmed of fat |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked for intensity |
| Fresh Rosemary 🌿 | ½ cup | Chopped sprigs, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Chopped leaves, stems removed |
| Garlic Cloves 🧄 | 4 cloves | Smashed for infusion |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crust development |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for searing |
| Water 💧 | 1 cup | For brine solution |

The beef tenderloin is non-negotiable here—center-cut with minimal fat ensures maximum tenderness. Butcher shops and high-end grocers like Whole Foods or Wegmans carry the best cuts, often labeled 'chateubriand' or 'filet mignon' (though tenderloin is the correct cut). If buying whole, trim excess silver skin and fat for even cooking. For herbs, fresh is non-negotiable—dried substitutes lack the aromatic depth needed for this technique. The rosemary and thyme should be vibrant green with no browning, indicating peak freshness. Costco's bulk herb section is surprisingly reliable for consistent quality.
No kosher salt on hand? Diamond Crystal is preferred due to its coarser grain, but Morton's at half the volume works in a pinch. Freshly cracked peppercorns are essential—they release more aroma than pre-ground. Substituting red wine? Dry sherry or beef broth maintains depth, though wine's acidity is ideal. For the high-heat sear, beef tallow or bacon fat creates the perfect crust—if unavailable, avocado oil works but lacks the same rich flavor. The olive oil should be extra-virgin with a peppery finish—California-based brands like Corto or Lucini deliver consistent quality. Prep the garlic by smashing cloves with the flat side of your knife—this releases more flavor without mincing.
Store the tenderloin uncovered in the fridge for 1-2 hours before cooking to dry the surface slightly—this ensures a better crust. The brine solution (salt, water, and smashed garlic) can be made 24 hours ahead and stored in the fridge. For the herbs, wrap them in damp paper towels and seal in a plastic bag—they'll stay fresh for 5-7 days. The red wine reduction can be prepped a day ahead and reheated gently. If prepping the entire roast ahead, keep it unseasoned until just before cooking to maintain optimal texture. The meat thermometer is your best friend—calibrate it beforehand for accuracy.

Step-by-step instructions for america's Test Kitchen beef tenderloin roast
Master the perfect balance of juicy interior and crispy exterior with this precision method.
Prepare the Herb-Infused Brine Solution
In a medium bowl, combine the 1 cup water, 1.5 tbsp kosher salt, 0.5 cup fresh rosemary, 0.25 cup fresh thyme, and 4 smashed garlic cloves. Stir until the salt fully dissolves, creating a fragrant brine. Place the 3 lb beef tenderloin in a large resealable plastic bag and pour the brine over it, ensuring complete coverage. Seal the bag and refrigerate for 24 hours, turning the tenderloin occasionally. This step guarantees even seasoning and optimal moisture retention throughout the roast.
After brining, remove the tenderloin and pat it thoroughly dry with paper towels—this critical step prevents steam buildup during roasting, which is essential for achieving that coveted crispy crust. Discard the used brine and proceed immediately to the next step while the meat is still cold.
Create the High-Heat Searing Mixture
In a small bowl, combine the 2 tbsp extra-virgin olive oil, 0.5 cup cold unsalted butter, and 2 tbsp beef tallow or bacon fat. This blend creates the ideal searing mixture—olive oil for flavor, butter for richness, and tallow for high-heat stability. Let this mixture sit at room temperature for 15 minutes before using, ensuring even distribution when applied to the meat.
Preheat your oven to 425°F with a rack positioned in the lower third. While the oven heats, use a paper towel to evenly coat the tenderloin with the searing mixture, pressing gently to adhere. This layer will form the foundation for your crispy crust while infusing deep flavor. Let the coated tenderloin rest at room temperature for 30 minutes before roasting.
Sear and Roast for Perfect Doneness
Heat a heavy oven-safe skillet over high heat until smoking hot. Place the tenderloin in the skillet and sear for 4 minutes per side, rotating occasionally to ensure even browning. The goal is to develop a deep mahogany crust—this is where the magic happens. Transfer the seared tenderloin to the preheated oven and roast for 20-25 minutes until the internal temperature reaches 125°F on the meat thermometer.
For the final touch, remove the tenderloin from the oven and pour the 0.5 cup red wine into the skillet, scraping up any browned bits. Let this reduce by half over medium-high heat for 3-4 minutes, creating a rich pan sauce. Return the tenderloin to the skillet, spooning the sauce over the top, and let it rest for 10 minutes before slicing against the grain.
Rest and Serve with Confidence
During the resting period, tent the tenderloin loosely with aluminum foil to retain heat while allowing the juices to redistribute. This crucial step prevents dryness and ensures each slice delivers maximum tenderness. After resting, slice the tenderloin into 1-inch thick medallions, fanning them slightly for presentation. Serve immediately with the reduced wine sauce drizzled generously over each portion.
The result should be a perfectly crispy exterior with a juicy, pink center—no gray bands in sight. The herb-infused crust will shatter slightly with each bite, revealing the tender, buttery interior. This method delivers restaurant-quality beef tenderloin every time, with precise temperature control and professional techniques.
Pro Tips For Making America'S Test Kitchen Beef Tenderloin Roast
- USE A MEAT THERMOMETER: The ATK recipe calls for medium-rare (130°F internal temp), but I learned the hard way—guessing leads to overcooked, dry meat. A good probe thermometer takes the guesswork out, and you can pull it just as the temp hits target without stressing.
- SALT THE MEAT 40 MINUTES EARLY: This isn’t just about seasoning—it’s about texture. The recipe’s kosher salt needs time to penetrate the tenderloin’s surface, creating that perfect crust while keeping the inside juicy. I used to skip this, and the crust never formed right.
- SKIP THE CROWDED PAN: When searing the tenderloin in the Dutch oven, resist the urge to add all the aromatics at once. Start with just the garlic and shallots in the hot oil—let them sizzle for 2 full minutes before adding herbs. This builds deeper flavor without burning.
- REST IT UNDER FOIL: The recipe says to rest the roast, but I used to leave it exposed on the cutting board. Wrap it loosely in foil for those 10–15 minutes—it traps heat better, keeps the juices from pooling out, and makes slicing cleaner. Your future self will thank you.
Best sauces and condiments for these flavors
Classic Red Wine Sauce
This bold red wine reduction is the perfect finishing touch for your tenderloin, amplifying the herbaceous notes from the crust. Deglaze the skillet with ½ cup bold Cabernet Sauvignon after searing, then reduce by half over medium-high heat for 3-4 minutes.
The sauce should coat the back of a spoon—thick enough to cling but still glossy. I like to finish it with a pinch of fresh thyme and a splash of beef stock for depth. 🍷
Herb Butter Glaze
For a lighter alternative, blend ¼ cup softened unsalted butter with 1 tbsp chopped rosemary, 1 tsp cracked black pepper, and 1 tsp minced garlic.
Spread this mixture over the tenderloin during the final 5 minutes of roasting, then broil for 2 minutes to create a golden, glossy crust. The butter melts into the meat, infusing it with aromatic richness. This works especially well if you prefer a less acidic sauce pairing. 🧈
Chimichurri Brightness
Balance the richness with a vibrant chimichurri—blend ½ cup chopped parsley, 2 tbsp chopped cilantro, 2 minced garlic cloves, 2 tbsp red wine vinegar, ½ cup olive oil, 1 tsp red pepper flakes, and 1 tsp kosher salt.
Spoon this over sliced tenderloin just before serving. The acidity cuts through the fat, while the herbs add a fresh contrast. I like to serve it alongside grilled vegetables for a complete South American-inspired meal. 🌿
Mushroom-Port Reduction
For a deeper, earthier sauce, sauté 1 cup sliced cremini mushrooms in the skillet after searing the tenderloin. Add ½ cup port wine and 1 tbsp balsamic vinegar, then reduce until syrupy. Finish with a pat of butter for shine.
This sauce pairs beautifully with the tenderloin's herbal notes, adding umami complexity. It's especially impressive for holiday dinners when you want to elevate the presentation. 🍄
Garlic-Honey Mustard
Create a sweet-savory contrast with a quick garlic-honey mustard sauce. Whisk together 2 tbsp Dijon mustard, 1 tbsp honey, 1 tbsp minced garlic, 1 tbsp olive oil, and 1 tsp apple cider vinegar.
Drizzle over sliced tenderloin and serve with roasted root vegetables. The tangy-sweet balance cleanses the palate between bites, making it a crowd-pleaser for all occasions. 🍯
Pan Jus Technique
Maximize flavor by creating a pan jus using the drippings from your roast. After removing the tenderloin, place the skillet over medium heat and add 1 cup beef stock. Scrape up any browned bits with a wooden spoon, then simmer until reduced by half.
Strain and serve alongside the tenderloin for dipping. This method uses every bit of flavor from your cooking process, ensuring nothing goes to waste. 🥄

Frequently asked questions
Why does America's Test Kitchen recommend brining the beef tenderloin?
The 24-hour herb brine enhances flavor and ensures moisture retention throughout the roast. The salt and aromatic herbs penetrate the meat, creating a more tender texture and deeper taste profile. This step is especially important for tenderloin, which can dry out if not properly seasoned and hydrated.
Can I cook the beef tenderloin to medium instead of medium-rare?
Yes, but adjust the internal temperature to 145°F for medium doneness. The reverse sear method still works perfectly—just reduce the final roasting time to 15-20 minutes instead of 20-25. For medium-rare, aim for 130-135°F internal temperature. Always use a meat thermometer for accuracy.
What's the best way to slice beef tenderloin for maximum tenderness?
Slice against the grain into 1-inch thick medallions for the most tender texture. The grain runs lengthwise, so cutting perpendicular ensures each bite has the shortest possible muscle fibers. For presentation, fan the slices slightly or stack them on a platter. Never slice too thin—this makes the meat tougher.
Can I use a regular oven instead of an oven-safe skillet?
If you don't have an oven-safe skillet, sear the tenderloin in a regular skillet first, then transfer it to a roasting pan. Place the pan on the oven rack and roast as directed. The key is maintaining the high-heat sear before the gentle finish in the oven. Just ensure your roasting pan has a rack for even heat circulation.
How do I fix an overcooked beef tenderloin?
If your tenderloin reaches 145°F+ and appears dry, don't panic. Slice it thinly against the grain and serve with a rich sauce like the red wine reduction or mushroom-port sauce to add moisture. For extra tenderness, slice and sear the pieces quickly in butter for 30 seconds per side before serving. This creates a flavorful crust while keeping the interior juicy.
