Ingredients for america's test kitchen pork tenderloin
Precision-cut ingredients and exact measurements ensure restaurant-quality pork tenderloin every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred for precise measurement |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns for optimal freshness |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cut into small cubes |
| Garlic Cloves 🧄 | 2 whole | Smashed with side of knife |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems discarded |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | Light fruity variety for balance |
| Yellow Onion 🧅 | ½ whole | Thinly sliced, outer layers removed |
| Fresh Lemon 🍋 | 1 whole | Zest and juice, seeds removed |
| Heavy Cream 🥛 | ¼ cup | Full-fat for optimal texture |
| Vegetable Oil 🫒 | 1 tbsp | For roasting pan preparation |
| Granulated Sugar 🍚 | ½ tsp | For caramelization enhancement |
The pork tenderloin selection is critical for consistent results. Center-cut pieces with visible marbling deliver optimal tenderness, while the silver skin should be meticulously trimmed to prevent undercooking. For sourcing, prioritize local butchers or high-quality grocery chains like Whole Foods where cuts are properly aged. The 1.5 lb portion ensures generous servings while maintaining even cooking. Fresh herbs are non-negotiable—rosemary and thyme from the bulk section at specialty markets provide superior flavor compared to dried alternatives. When selecting garlic, choose plump cloves with papery skins that yield easily when pressed.
Substitutions should maintain the recipe's scientific balance. For the dry brine, Diamond Crystal kosher salt—if using Morton's, reduce by 20% to avoid over-salting. The butter can be substituted with ghee for dairy-free adaptation, though texture may slightly differ. In a pinch, olive oil instead of vegetable oil works for the roasting pan, though it may impart subtle flavor. For the herb blend, dried herbs at one-third quantity suffice, though fresh is ideal. The lemon zest can be omitted if unavailable, but the juice is essential for acid balance—bottled lemon juice works in a bind though fresh is preferred for brightness.
Proper storage and preparation maximize the recipe's success. The 24-hour dry brine is non-negotiable—this critical step transforms the meat's texture. Store the brined pork uncovered on a wire rack in the refrigerator to allow for even air circulation. The herb mixture can be prepped 1 day ahead and stored in an airtight container. For optimal freshness, use the pork within 3 days of purchase and cook immediately after brining. Leftovers reheat beautifully—warm in a 325°F oven for 10-15 minutes covered with foil to retain moisture, or use within 3 days refrigerated. The herb mixture keeps for 5 days refrigerated or 3 months frozen.

Step-by-step instructions for science-backed pork tenderloin
Precision timing and proper technique transform this lean cut into a juicy, flavorful centerpiece.
Prepare the Pork with Precision Seasoning
Pat the 1.5 lb pork tenderloin completely dry with paper towels, removing all moisture from the surface. This step is critical—wet skin prevents proper browning and crust formation. Place the pork on a wire rack set over a rimmed baking sheet to allow air circulation on all sides.
In a small bowl, combine the 1.5 tsp kosher salt and 0.5 tsp freshly ground black pepper. Rub this mixture evenly over the entire surface of the pork, pressing gently to ensure the seasoning adheres. Let the seasoned pork rest at room temperature for 30 minutes while you prepare the aromatics. This resting period ensures even cooking and prevents temperature shock when it hits the hot pan.
Build the Herb Butter and Sear the Pork
In a small saucepan, melt the 2 tbsp unsalted butter over low heat. Remove from heat and stir in the 2 smashed garlic cloves, 0.25 cup finely chopped fresh rosemary, 0.25 cup fresh thyme leaves, and 0.5 tsp granulated sugar. Let this herb butter mixture cool slightly while you prepare the searing station.
Heat a large oven-safe skillet over medium-high heat until very hot (about 375°F). Add 1 tbsp vegetable oil and swirl to coat the pan evenly. Carefully place the pork tenderloin in the skillet, turning to coat with oil. Sear for 4-5 minutes on each side until the exterior develops a deep golden-brown crust. The internal temperature should read 140°F at this point.
Roast to Perfect Doneness
Transfer the skillet to a preheated 425°F oven and roast for 10-12 minutes, rotating the pan halfway through cooking. The pork is done when the internal temperature reaches 145°F and a meat thermometer inserted into the thickest part shows a 3-minute carryover rise to 148°F. This precise temperature ensures perfect doneness without drying out the meat.
During the last 2 minutes of roasting, remove the skillet from the oven and increase heat to broil. This final step creates a caramelized crust while keeping the interior juicy. Watch closely to prevent over-browning.
Rest and Finish with Herb Cream Sauce
Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 10 minutes—this critical step allows juices to redistribute throughout the meat. While the pork rests, return the skillet to the stovetop over medium heat and add the 0.5 whole thinly sliced yellow onion. Cook for 3-4 minutes until softened.
Pour in the 0.25 cup heavy cream and the herb butter mixture, scraping up any browned bits from the pan. Simmer for 2-3 minutes until the sauce thickens slightly. Finish with the zest and juice of 1 whole fresh lemon and adjust seasoning with additional salt if needed.
Slice and Serve with Confidence
Slice the pork tenderloin into ½-inch thick medallions against the grain. The meat should be tender enough to pull apart with gentle pressure but still hold its shape. Arrange the slices on warm plates and spoon the herb cream sauce generously over the top.
Serve immediately with roasted vegetables or a fresh herb salad. The result is a perfectly tender, juicy pork tenderloin with a rich herb cream sauce that complements every bite. The science-backed method ensures consistent results every time, without the need for breading or glues that mask the natural flavor of the meat.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- USE A THERMOMETER: The recipe calls for medium-rare (140°F internal temp), but I learned the hard way—pork keeps cooking after you pull it from the pan. If you don’t have one, err on the side of undercooking slightly and let it rest longer. (Yes, even if you’re impatient like me.)
- SALT THE GARLIC CLOVES: Those whole garlic cloves in the butter? Toss them in a pinch of kosher salt first—they’ll caramelize faster and add depth. I used to skip this, and the flavor was always just… there, not popping like it should.
- DON’T OVERCROWD THE PAN: The recipe says to sear the pork in batches, but I’ve seen people ignore that and end up with sad, steamed pork instead of crispy edges. A 1-inch gap between pieces ensures they brown properly—no excuses.
- REST THE PORK LONGER: America’s Test Kitchen insists on 10 minutes under foil, but I now add 5 extra. The meat firms up, juices redistribute, and slicing becomes a breeze. (Your future self will thank you for not rushing this.)

This method lets you focus on guests instead of cooking—pure genius for busy hosts! ✨

Frequently asked questions
Why does this recipe use a 24-hour dry brine instead of just salting before cooking?
The dry brine transforms the meat's texture by breaking down tough muscle fibers and retaining moisture. This 24-hour process creates a silky, melt-in-your-mouth result that's impossible to achieve with last-minute seasoning. The salt penetrates deeply, while the resting period on a wire rack ensures even cooking and prevents a dry exterior.
Can I cook pork tenderloin from frozen?
While possible, it's not recommended for optimal results. Frozen pork can release moisture unevenly, leading to inconsistent browning. If you must cook from frozen, thaw it in the refrigerator overnight first. For best results, always use fresh or previously frozen pork that's been fully thawed and patted completely dry before seasoning.
What's the best way to check doneness without overcooking?
Use a meat thermometer inserted into the thickest part of the pork. Remove it when it reaches 145°F—this accounts for the 3-minute carryover rise to 148°F. The thermometer should be in the center of the meat, not touching bone. Never rely on visual cues alone, as pork can look cooked on the outside while remaining underdone inside.
How do I prevent the pork from drying out?
The key is proper temperature control and resting. Roast at 425°F for 10-12 minutes max after searing, then finish with broil for just 2 minutes. The 10-minute rest after cooking is critical—it allows juices to redistribute. Avoid cutting into the pork immediately, as this releases precious moisture.
What are the best sides to serve with this pork tenderloin?
Classic pairings include herb-roasted potatoes, crisp apple salad, or sautéed green beans with garlic. For a heartier meal, try mashed sweet potatoes or wild rice pilaf. The herb cream sauce also complements steamed asparagus or roasted Brussels sprouts** beautifully. The key is balancing rich flavors with fresh, bright components.
