Ingredients for america's test kitchen pork tenderloin
Precision ingredients for clockwork pork tenderness—no shortcuts, just perfect results.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🐖 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred, freshly ground |
| Fresh Thyme Leaves 🌿 | ½ tsp | From 2 sprigs, finely chopped |
| Fresh Rosemary Leaves 🌿 | ½ tsp | From 1 sprig, finely chopped |
| Black Peppercorns 🌶️ | ½ tsp | Freshly cracked |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For brushing, high-quality preferred |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for crust |
| Garlic Cloves 🧄 | 2 cloves | Minced for herb rub |
| Fresh Parsley Leaves 🌿 | ¼ cup | Chopped for garnish |
| All-Purpose Flour 🌾 | 1 tbsp | For dredging if needed |
The pork tenderloin must be center-cut and uniform in size—Whole Foods or local butchers carry the best quality. Look for pieces with even diameter and minimal connective tissue. Trader Joe's often has pre-trimmed tenderloins, saving prep time. Fresh herbs make all the difference: Williams Sonoma or Costco bulk bins offer superior quality over grocery store bundles. The Diamond Crystal kosher salt is essential—it dissolves more easily than table salt, ensuring even seasoning. For the olive oil, California Olive Ranch or Bertolli extra-virgin varieties provide the right balance of fruitiness and heat resistance for roasting.
No fresh thyme? Dried thyme at one-third the amount works, but fresh delivers superior aroma. Substituting lemon zest for rosemary adds brightness if needed. The butter crust requires full-fat, unsalted butter—Plugrá or Land O'Lakes work well. For garlic, minced jarred is acceptable in a pinch, though fresh has better flavor. If your tenderloin is uneven, lightly dredge in all-purpose flour before searing to create a more consistent crust. The herb rub should be applied 30 minutes before cooking to allow full penetration—this is non-negotiable for even seasoning.
Store fresh herbs wrapped in damp paper towels for up to 5 days in the fridge. The seasoned tenderloin can rest, uncovered, on a wire rack for up to 2 hours before cooking without drying out. Leftovers reheat best at 350°F for 10-12 minutes, covered loosely with foil. For maximum freshness, portion into airtight containers with a thin layer of olive oil on top to preserve moisture. The crust will soften slightly upon reheating—re-crisp in a hot skillet if desired.

Step-by-step instructions for america's test kitchen pork tenderloin
Precision timing and technique guarantee perfectly tender, juicy pork every time.
👨🍳 Step 1: Prep the Pork for Even Cooking
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this ensures maximum browning. Trim any remaining silver skin and tie the pork with kitchen twine at 1-inch intervals to maintain uniform shape during cooking. The twine prevents curling and helps the meat cook evenly throughout.
In a small bowl, combine the 1.5 tsp kosher salt, 0.5 tsp fresh thyme leaves, 0.5 tsp fresh rosemary leaves, 0.5 tsp black peppercorns, and 2 minced garlic cloves. Rub this mixture all over the pork, pressing firmly so the herbs adhere. Let it rest at room temperature for 30 minutes before cooking—this ensures even heat distribution and better seasoning penetration.
🔥 Step 2: Sear for Crispy Texture and Flavor
Heat a large oven-safe skillet over medium-high heat until very hot. Add the 1 tbsp extra-virgin olive oil and swirl to coat the pan. Place the pork in the skillet and sear for 3-4 minutes per side until deep golden brown. The pork should release easily from the pan when ready to flip—this indicates proper searing.
Remove the skillet from heat and add the 2 tbsp cold unsalted butter to the pan. Tilt the skillet and spoon the melted butter over the pork, basting it thoroughly. This step locks in moisture and adds rich flavor. Return the skillet to the heat for 30 seconds to melt the butter completely.
🔥 Step 3: Roast to Perfect Doneness
Preheat your oven to 400°F. Transfer the skillet to the oven and roast the pork for 15-20 minutes, or until the internal temperature reaches 145°F on a meat thermometer. The pork is done when it's juicy and tender—overcooking leads to dryness, so don't walk away during this step.
For extra insurance, tent the pork loosely with aluminum foil during the last 5 minutes of cooking if the outside begins to brown too quickly. This prevents over-browning while maintaining the internal temperature. The pork should have a golden crust and be fork-tender when pierced.
⏰ Step 4: Rest and Garnish for Maximum Juiciness
Transfer the pork to a cutting board and let it rest for 10 minutes before slicing. This resting period allows the juices to redistribute, ensuring each slice remains moist and flavorful. Skipping this step results in dry, stringy meat—don't rush it.
Slice the pork into ½-inch thick medallions and arrange on a serving platter. Garnish with the 0.25 cup chopped fresh parsley leaves and a sprinkle of flour (if desired) for a light, crispy finish. Serve immediately with your favorite sides for a restaurant-quality meal.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- USE A MEAT THERMOMETER: I learned this the hard way—pork tenderloin can go from perfect to dry in seconds. Bury the probe in the thickest part; pull it at 145°F internal temp (it’ll rest to 140°F). No guessing, no overcooking.
- SALT THE PORK 40 MINUTES EARLY: This isn’t just seasoning—it’s flavor infusion. Sprinkle the kosher salt all over the tenderloin (about 1 tsp per pound) and let it sit uncovered in the fridge. The salt breaks down the muscle fibers, and the meat stays juicier when seared.
- DON’T SKIP THE ROOM-TEMP EQUALIZATION: Take the pork out of the fridge 30 minutes before cooking. Cold meat sears poorly and releases juices into the pan instead of staying inside. Room temp = better crust, better flavor—no excuses.
- STIR THE HERB BUTTER FAST: When mixing the herb butter (thyme, rosemary, peppercorns), chop the herbs finely but not into paste—you want texture, not mush. Work quickly so the butter doesn’t melt into a greasy blob before you seal it in the fridge. (Yes, even if you’re impatient like me.)
Wine and beer pairings for this america's test kitchen pork tenderloin
Crisp White Wine
For this delicate pork tenderloin, I reach for a dry Riesling from the Mosel region—its bright acidity and subtle mineral notes cut through the rich butter crust while complementing the thyme and rosemary.
A 2021 Dr. Loosen Blue Slate ($25) is my go-to; its crisp finish matches the pork's clean, herbaceous profile. Serve slightly chilled to enhance the wine's freshness. 🍷
Light-Bodied Red
If you prefer red, a Pinot Noir from Oregon's Willamette Valley offers the perfect balance. The 2021 Domaine Serene Pinot Noir ($45) has red fruit and earthy undertones that harmonize with the pork's caramelized crust.
Avoid heavy Cabernets—they'll overpower the tenderloin's delicate flavors. Decant for 30 minutes before serving to soften tannins.
Craft Beer Pairings
A Belgian witbier like Allagash White ($12) brings citrusy brightness and subtle spice that mirrors the herb rub's complexity. For a malty option, try a German Helles like Weihenstephaner Original ($10)—its clean, toasty notes complement the pork's buttery crust. Serve both beers well-chilled to preserve their crisp profiles.
Unexpected Sparkling
Don't overlook dry sparkling wine—a Prosecco from Italy's Valdobbiadene region adds effervescence that cleanses the palate between bites. La Giustina Prosecco Superiore ($18) delivers honeyed apple and almond notes that pair beautifully with the pork's herbaceous crust. Serve in fluted glasses at 45°F for optimal flavor.
Regional Southern Twist
For a true Southern touch, pair with a Georgia Chardonnay like Chateau Elan ($20)—its buttery texture and citrus undertones echo the pork's butter crust. If you're grilling outdoors, a local craft lager from Atlanta's Three Trees Brewing adds a refreshing contrast to the smoky grill notes. 🍺

Frequently asked questions
Why does the America's Test Kitchen pork tenderloin recipe call for tying the meat?
Tying the pork with kitchen twine at 1-inch intervals prevents it from curling during cooking, ensuring even heat distribution and a uniform shape. This technique guarantees consistent doneness throughout the entire piece, especially important since pork tenderloin can vary in size. Without tying, thicker sections may overcook while thinner areas stay underdone.
Can I substitute dried herbs for fresh in this recipe?
Yes, but use one-third the amount of dried herbs (e.g., ⅓ tsp dried thyme instead of ½ tsp fresh). Fresh herbs provide superior aroma and flavor, but dried works in a pinch. For best results, crush dried herbs between your fingers to release their oils before applying to the meat. The herb rub should still be applied 30 minutes before cooking for maximum penetration.
What if my pork tenderloin is uneven in size?
If your tenderloin isn't uniform, lightly dredge the thicker sides in 1 tbsp flour before searing to create a protective barrier. This prevents overcooking while the thinner sections brown. For extra insurance, use a meat thermometer and remove the pork when the thickest part hits 145°F. The flour also adds a subtle crunch that complements the butter crust.
How can I tell when pork tenderloin is fully cooked without a thermometer?
Use the fork test: Insert a fork into the thickest part—if the juices run clear (not pink or red) and the meat reaches fork-tender (easily pierced) but still slightly springy, it's done. The internal color should be light pink in the center. For extra confidence, cut into the thickest section: it should be juicy and tender, not dry or rubbery.
Can I make this recipe on the grill instead of in the oven?
Sear the pork over medium-high heat for 3-4 minutes per side, then move to indirect heat (about 350°F) and cook until the internal temperature reaches 145°F (15-20 minutes). Baste with melted butter every 5 minutes to maintain moisture. The grill imparts wonderful smoky notes while keeping the meat tender—just monitor closely to avoid flare-ups.
