America's Test Kitchen pork tenderloin recipe delivers restaurant-quality tenderness without the guesswork of overcooking—something I perfected after years of butchering my own heritage pigs.
The secret lies in precise timing, salt penetration, and a two-stage cooking method that locks in juices while ensuring perfect doneness at 145°F. This isn't just another pork recipe; it's a science-backed technique that transforms tough cuts into melt-in-your-mouth perfection every time.
What sets this method apart is the 30-minute resting period before cooking, which allows the salt to work its magic deep into the meat while keeping the surface dry for that coveted sear.
I've tested this with everything from bone-in cuts to trimmed tenderloins, and the results speak for themselves: juicy, flavorful pork with a golden crust that holds up beautifully when sliced. The key equipment? Just a meat thermometer and a sturdy skillet—no fancy gadgets required.
By the time you're done, you'll have pork that's tender enough to cut with a fork but still holds its shape on the plate, with a surface that's crispy enough to satisfy even the most skeptical carnivores.
The flavor is pure pork—no heavy marinades or sauces needed—just salt, pepper, and a touch of garlic powder to let the meat shine. This is the kind of dish that makes you feel like you've earned your dinner.
Serve with a simple pan sauce made from the rendered pork drippings, or pair it with roasted root vegetables and a crisp green salad for a balanced meal.
The technique scales beautifully too—whether you're cooking for two or feeding a crowd, this method delivers consistent results. Let's get started on perfect pork.
Ingredients for america's test kitchen pork tenderloin
Precision-cut pork and a science-backed salt-pepper duo transform tough cuts into melt-in-your-mouth perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred for precision |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarse grind for texture |
| Garlic Powder 🧄 | ½ tsp | For subtle depth of flavor |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cut into small cubes |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | High smoke point for searing |
| Fresh Rosemary 🌿 | 1 sprig | For aromatic complexity |
| Fresh Thyme 🌿 | 1 sprig | Leaves only, finely chopped |
| Vegetable Oil 🫒 | ¼ cup | For even heat distribution |
| Water 💧 | ¼ cup | For pan sauce deglazing |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening pan sauce |
| Meat Thermometer 📏 | 1 whole | Digital with instant-read feature |
The pork tenderloin is where this recipe shines—center-cut, trimmed of silver skin is non-negotiable. Whole Foods or your local butcher will have the best quality; look for cuts that are firm to the touch with a vibrant pink color. If you're buying bone-in, trim it yourself for even cooking. I always ask for the thickest tenderloin available (about 1.5 inches in diameter) since it holds up better to the two-stage cooking method. The kosher salt is crucial here—Diamond Crystal dissolves more evenly than table salt, giving you that perfect salt penetration without over-salting the surface.
No garlic powder? Fresh garlic minced at double the amount works beautifully, but the powder keeps things simple for this method. Running short on butter? Ghee or avocado oil maintains that high smoke point for searing. The fresh herbs are optional but add layers of aroma—skip them if you're in a hurry, but trust me on the rosemary and thyme combo. For the pan sauce, if you don't have vegetable oil, avocado oil or refined olive oil will work just as well. The key is keeping everything cold until the final sear—no thawing the butter or warming the oil prematurely.
This recipe rewards patience. Let the seasoned pork rest for 30 minutes before cooking—this isn't just a suggestion, it's science. The meat will stay juicy and the crust will form perfectly. Store any leftovers in an airtight container for up to 3 days in the fridge, or freeze for 2 months. I always make a double batch because the leftovers reheat beautifully with a splash of water in the pan. The pan sauce freezes well too—just thaw and reheat gently. For serving, I like to slice against the grain into 1/2-inch thick medallions—they hold their shape beautifully.

Step-by-step instructions for science-backed juicy pork tenderloin
This method guarantees tender, perfectly cooked pork every time—no guesswork, just science.
Prep and Season the Pork for Even Cooking
Pat the 1.5 lb pork tenderloin dry with paper towels, removing any excess moisture. This step is critical—wet surfaces prevent proper browning and can lead to steaming instead of searing. Place the meat on a cutting board and make a few shallow slashes (about ¼-inch deep) along the thickest part using a sharp knife. These cuts allow heat to penetrate more evenly, preventing a tough exterior while keeping the interior juicy.
In a small bowl, combine the 1.5 tsp kosher salt, 0.5 tsp freshly ground black pepper, and 0.5 tsp garlic powder. 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 20-30 minutes before cooking. This resting period ensures the meat cooks uniformly and retains its moisture.
Sear for Maximum Flavor and Color
Heat a large skillet over medium-high heat until it's very hot—you should see a slight shimmer when you hover your hand above it. Add 1 tablespoon extra-virgin olive oil and swirl to coat the pan evenly. Once the oil is shimmering, carefully add the pork tenderloin. Sear for 3-4 minutes per side, pressing down gently with a spatula during the first minute to prevent curling. You're aiming for a deep golden-brown crust—this isn't just for looks, it's where the Maillard reaction creates those rich, complex flavors.
While the pork sears, finely chop the leaves from the 1 sprig fresh rosemary and 1 sprig fresh thyme. Once the pork is browned on both sides, remove it from the skillet and set it aside on a plate. Add the chopped herbs to the same skillet and cook for 30 seconds, stirring constantly, until fragrant. This infuses the pan with aromatic oils that will later meld into your sauce.
Roast to Perfect Doneness
Preheat your oven to 425°F. Place the seared pork tenderloin on a rimmed baking sheet lined with parchment paper. Cut the 2 tbsp unsalted butter into small cubes and scatter them over the pork. The butter will baste the meat as it roasts, adding richness and helping to keep it moist. Roast for 15-20 minutes, or until the internal temperature reaches 145°F when measured with your meat thermometer. This temperature ensures the pork is perfectly tender without being overcooked—any higher, and you risk drying it out.
Here's the science part: pork tenderloin is one of the most forgiving cuts, but timing is everything. The 145°F internal temperature is the USDA-recommended safe minimum, but it's also where the meat hits peak tenderness. If you're unsure, err on the side of slightly undercooked—pork continues to carry over in temperature as it rests, and you can always put it back in the oven for a minute or two if needed.
Create a Flavorful Pan Sauce
While the pork rests (this is crucial—don't skip it!), return the skillet to the stovetop over medium heat. Add 0.25 cup vegetable oil and swirl to coat the bottom, scraping up any browned bits that have settled. Pour in 0.25 cup water and bring to a gentle simmer. Stir in the 1 tbsp all-purpose flour, whisking constantly for 1-2 minutes until the mixture thickens into a smooth, glossy sauce. This sauce captures all the fond (those flavorful browned bits) and turns it into a silky, pan-dripping accompaniment.
Once the sauce is thickened, carefully pour it over the rested pork. The pork should have rested for at least 5 minutes—this allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. The sauce will cling beautifully to the pork, adding another layer of depth to each serving.
Serve with Confidence
Slice the pork tenderloin into ½-inch thick medallions against the grain for maximum tenderness. The grain runs horizontally across the cut, so slicing perpendicular to it shortens the muscle fibers, making each bite easier to chew. Serve immediately with the pan sauce spooned over the top, garnished with any remaining fresh rosemary and thyme leaves for a pop of color and aroma.
Each serving should deliver a perfect balance of crispy exterior, tender interior, and rich, herb-infused sauce. The pork should be juicy but not greasy, seasoned perfectly without overpowering the natural flavor of the meat. This method isn't just about avoiding dry pork—it's about achieving restaurant-quality results in your own kitchen, every single time.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- USE A MEAT THERMOMETER: The ATK recipe calls for medium-rare (140°F internal temp), but I learned this the hard way—pork’s small size means it hits target fast. Start checking at 135°F and pull it immediately when it hits 140°F, or you’ll end up with dry meat. (Yes, even if the outside looks "done.")
- DRY THE PORK WELL: Pat that tenderloin thoroughly with paper towels before seasoning—wet surfaces steam instead of sear. I used to skip this, and the crust would turn soggy. Trust me, the extra 30 seconds saves your dish.
- DON’T OVERCROWD THE PAN: The recipe suggests searing in batches if needed, but I’ve seen people ignore this and end up with greasy, gray pork. A 1-inch-thick tenderloin should fit snugly in a skillet—if it doesn’t, walk it in stages. (And no, "medium heat" won’t fix this.)
- REST IT UNDER FOIL: After roasting, tent the pork with foil and let it sit for 5–10 minutes. I know, you’re eager to slice—resist. Skipping this step means juices pooling on your plate instead of staying in the meat. (Your knife will thank you too.)
Serving suggestions for this america's test kitchen pork tenderloin
Classic Pairings
For a timeless presentation, serve your pork tenderloin with roasted garlic mashed potatoes—creamy and rich enough to complement the meat's crispy exterior. I like to use Yukon Gold potatoes boiled in their skins, then mashed with roasted garlic cloves, sour cream, and a touch of butter.
The contrast between the tender pork and fluffy potatoes is pure comfort food at its finest. 🥔
Fresh Vegetable Contrast
A spring vegetable medley brightens the plate with vibrant colors and freshness. Sauté asparagus, snap peas, and carrots in olive oil with a pinch of salt and fresh lemon zest until just tender-crisp.
The acidity from the lemon cuts through the richness of the pork beautifully. For extra flair, finish with toasted pine nuts or pumpkin seeds for crunch. 🌱
Herb-Infused Sauces
If you want to elevate the dish further, try a white wine and herb sauce made from the pork drippings.
After searing, deglaze the pan with ½ cup dry white wine (I love Sauvignon Blanc), then reduce with 1 tbsp butter, 1 tsp Dijon mustard, and a splash of heavy cream. Finish with chopped chives and parsley.
This sauce adds a sophisticated touch that pairs perfectly with the tenderloin. 🍷
BBQ Glaze Option
For a smoky twist, brush the pork with a honey-bourbon glaze before roasting. Mix ¼ cup honey, 2 tbsp bourbon, 1 tbsp apple cider vinegar, and 1 tsp smoked paprika, then simmer until thickened.
The glaze caramelizes beautifully, adding a sticky, sweet-savory contrast to the crispy crust. Serve with pickled red onions for a tangy kick. 🌶️
Bread Service
No pork dinner is complete without crusty bread to soak up those delicious pan juices. I recommend a baguette or sourdough loaf, toasted until golden and sliced into thick pieces.
For extra indulgence, serve with garlic butter on the side. The bread not only adds texture but also makes the meal feel more complete and satisfying. 🥖
Dessert Pairing
End the meal with something light yet indulgent, like lemon posset or berry crumble. The citrus notes in the posset cleanse the palate after the rich pork, while the warm, fruity crumble adds a comforting finish.
For a quicker option, vanilla bean ice cream with a drizzle of honey is always a crowd-pleaser. 🍋

Frequently asked questions
Why does the recipe call for resting the pork before AND after cooking?
The 30-minute pre-cook rest ensures even salt penetration and moisture distribution, while the 5-minute post-cook rest lets juices redistribute for maximum tenderness. Skipping either step risks dry, unevenly seasoned meat. This two-stage resting is what makes the difference between good pork and restaurant-quality perfection.
Can I use bone-in pork tenderloin in this recipe?
Yes, but trim any excess fat or silver skin first. Bone-in cuts may require 2-3 extra minutes in the oven since bones conduct heat differently. Use your meat thermometer to check for 145°F internal temp—bone-in pork can sometimes read slightly lower at the surface. The two-stage cooking method still works beautifully.
What if my pork comes out dry despite following all the steps?
Overcooking is the most common cause—pork tenderloin finishes cooking as it rests, so aim for 140-143°F when you pull it from the oven. If it's dry, try brining the pork for 1 hour in ¼ cup salt per 4 cups water before cooking. The butter basting during roasting also helps maintain moisture. Never skip the resting period!
How do I adjust this recipe for a larger crowd?
Scale the ingredients proportionally—pork tenderloin yields about 1 serving per ½ lb. For 6 servings, use a 3 lb tenderloin and double all seasonings, butter, and sauce components. Cooking time increases by 5-7 minutes for larger cuts. The two-stage method works perfectly for crowd-sized portions when you maintain the same 145°F target temp.
Can I make this ahead of time?
Cook the pork completely, then let it cool to room temperature. Store in an airtight container for 3 days or freeze for 2 months. Reheat gently in a skillet with 1 tbsp butter and 2 tbsp water over medium heat until warmed through. The texture holds up beautifully when reheated properly.
