This America's Test Kitchen pork loin recipe delivers restaurant-quality results with a foolproof reverse-sear technique that guarantees perfect doneness every time.
After years of perfecting pork at Atlanta The Smoky Pig, I've adapted ATK's precision methods to create a dish that's tender, juicy, and deeply flavorful without requiring a thermometer—though I'll show you how to use one for foolproof results.
The secret lies in the reverse-sear method: starting with a low oven temperature to cook the pork evenly, then finishing with a high-heat sear for a caramelized crust. This approach eliminates the risk of overcooking while creating that coveted golden-brown exterior.
With just five simple ingredients—pork loin, olive oil, salt, pepper, and optional herbs—you'll achieve a dish that's elegant enough for dinner parties but simple enough for weeknights.
What you'll end up with is pork loin that's perfectly cooked through to 145°F with a juicy, tender interior and a crisp, flavorful crust. The reverse-sear method ensures even doneness, so no more dry or overcooked pork.
This technique transforms a simple cut of meat into a showstopping centerpiece that pairs beautifully with roasted vegetables, mashed potatoes, or a fresh salad.
Whether you're feeding a family or hosting guests, this recipe delivers professional-quality results with minimal effort. The key is patience and precision—letting the pork cook slowly before finishing with a quick sear. Ready to master this technique? Let's get started with a dish that's as impressive as it is delicious.
Ingredients for america's test kitchen pork loin
Five essential ingredients for restaurant-quality pork loin that delivers perfect doneness every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Center-Cut Pork Loin 🥩 | 1 ½ lb | 1.5-inch thick cut, bone-in preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High-quality, fruity, cold-pressed |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred for precise measurement |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarsely ground for texture |
| Fresh Rosemary 🌿 | 1 tbsp | Finely chopped, stems removed |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, finely chopped |
| Garlic Cloves 🧄 | 3 cloves | Minced, for crust enhancement |
The center-cut pork loin is non-negotiable for this technique—look for a 1.5-inch thick cut with visible fat marbling for moisture. Whole Foods or local butcher shops often carry premium cuts, but most grocery stores stock adequate options. If buying pre-portioned, ensure the thickness matches; thinner cuts will overcook during the sear. For maximum flavor, bone-in pork loin develops deeper caramelization. The herbs—fresh rosemary and thyme—should be vibrant green with no wilting; Trader Joe's bulk section is ideal for affordable, high-quality options.
No fresh rosemary? Dried rosemary at one-third the amount works, though the flavor will be less pronounced. Garlic powder can substitute minced garlic, but fresh is preferred for its aromatic depth. The olive oil must be extra-virgin for optimal heat resistance and flavor; California avocado oil is another excellent alternative. For salt, Diamond Crystal kosher salt measures differently than Morton—use a 1:1 ratio by volume if switching brands. The black pepper should be freshly ground to avoid bitterness, and coarsely ground for better texture retention during searing.
Pork loin should be refrigerated until ready to use, ideally within 24 hours of purchase. The herbs can be chopped and stored in an airtight container for up to 5 days in the fridge. For long-term storage, freeze the pork loin unseasoned for up to 6 months; thaw overnight in the fridge before cooking. The reverse-sear method allows for make-ahead flexibility—season the pork up to 2 hours ahead, then proceed with cooking when ready. Leftover pork loin reheats beautifully in a 350°F oven for 10-15 minutes, wrapped in foil.

Step-by-step instructions for perfectly cooked pork loin
Master the reverse-sear technique for a juicy interior and crisp exterior every time.
Prepare the Pork Loin for Even Cooking
Remove the pork loin from the refrigerator and let it sit at room temperature for 30 minutes. This ensures even cooking throughout the thick cut. Pat the loin dry with paper towels—moisture is the enemy of a good sear. The surface should feel completely dry to the touch.
In a small bowl, combine the 1.5 teaspoons kosher salt, 0.5 teaspoon freshly ground black pepper, 1 tablespoon finely chopped fresh rosemary, and 1 tablespoon finely chopped fresh thyme. Rub this mixture evenly over all sides of the pork loin, pressing gently to help the seasoning adhere. Let it rest uncovered on a wire rack for 15 minutes—this allows the seasoning to penetrate slightly and the surface to dry further, which is crucial for that perfect crust.
Low-Temperature Oven Cook to Medium Doneness
Preheat your oven to 275°F. Place the pork loin on a wire rack set inside a rimmed baking sheet to allow air circulation on all sides. This low-temperature cook ensures the center reaches 140°F without overcooking the exterior. Insert an instant-read thermometer into the thickest part of the loin—it should read 140-145°F when done.
Cook for approximately 45-55 minutes, depending on thickness. The pork is done when the internal temperature hits 140°F and the meat feels slightly springy to the touch. Remove it from the oven and let it rest on the baking sheet for 10 minutes—this resting period is critical for redistributing juices and ensuring a tender, moist final product.
High-Heat Sear for Crisp Exterior
While the pork rests, heat a large skillet over high heat until it's smoking hot. Add the 2 tablespoons extra-virgin olive oil and let it shimmer. Place the pork loin in the skillet, fat-side down first, and sear for 2-3 minutes until the surface develops a deep golden-brown crust. Flip carefully and sear the other side for another 2-3 minutes, pressing down gently with a spatula to ensure even contact.
For extra flavor, add the 3 minced garlic cloves to the skillet during the last 30 seconds of searing—they'll release their aroma and infuse the crust. The garlic should sizzle and turn golden, not burn. Transfer the seared pork to a cutting board and let it rest for an additional 5 minutes before slicing.
Slice and Serve with Confidence
Slice the pork loin against the grain into ½-inch thick medallions. The grain runs lengthwise, so cutting perpendicular to it shortens the muscle fibers for maximum tenderness. Each slice should be juicy and pink in the center, with a crisp, flavorful crust. Serve immediately with your favorite sides—roasted vegetables, mashed potatoes, or a fresh salad pair beautifully.
This reverse-sear method guarantees a perfectly cooked pork loin every time, with a juicy interior and a crisp exterior that locks in all the flavors. The key is patience—letting the meat cook slowly first, then finishing with a high-heat sear for that restaurant-quality crust.
Pro Tips For Making America'S Test Kitchen Pork Loin
- USE A MEAT THERMOMETER: After searing, the pork needs to hit 145°F internally—no guessing. I learned this the hard way by slicing into rubbery meat that was "close enough." The second the thermometer reads 145°F, pull it from the oven. That’s the only way to nail juicy, tender slices every time.
- SALT THE PORK 40 MINUTES EARLY: The recipe calls for salting before cooking, but don’t wait until the last minute. Slather the pork with salt and let it sit uncovered in the fridge for 40 minutes—this seasons deeper and prevents dryness. I used to skip this, and the crust never tasted as rich.
- SKIP THE CROWDED PAN: When searing, resist the urge to pile rosemary sprigs on top like confetti. Spread them out in a single layer—overcrowding steams the pork instead of browning it. A few minutes of patience here means a crisp, aromatic crust instead of a sad, soggy one.
- CHOP ROSEMARY COARSELY: Fresh rosemary needs space to release its flavor. Instead of mincing it into oblivion, chop it into 1-inch sprigs—big enough to stay intact during searing but small enough to infuse the meat. I was skeptical until I tried it: the aroma hits you the second you open the oven door.
Perfect pairings for this america's test kitchen pork loin
Classic Southern Sides
Nothing complements this pork loin like creamy mashed potatoes—I use Yukon Gold potatoes boiled until tender, mashed with ½ cup unsalted butter, ½ cup whole milk, and ½ teaspoon salt.
The richness balances the pork’s herbal notes beautifully. For extra flair, fold in roasted garlic from the same oven session. 🥔
Fresh Herb Salad
A cucumber and herb salad with red onion, fresh dill, and a lemon-olive oil dressing adds a refreshing contrast. Thinly slice 1 English cucumber and ½ red onion, toss with 2 tablespoons chopped dill, 1 tablespoon lemon juice, and 2 tablespoons extra-virgin olive oil.
The crispness cuts through the richness of the pork perfectly. 🥒
Roasted Vegetable Medley
Roast carrots, Brussels sprouts, and sweet potatoes at 400°F for 25-30 minutes with 1 tablespoon olive oil, ½ teaspoon salt, and ½ teaspoon smoked paprika. The caramelized edges pair wonderfully with the pork’s crust. I often use Trader Joe’s pre-cut veggie mixes for convenience. 🍠
Wine Pairings
A dry Riesling from Germany—like Dr. Loosen Blue Slate—complements the pork’s herbal notes with its crisp acidity and subtle honeyed finish. For red wine lovers, a Pinot Noir from Oregon, such as Domaine Serene, enhances the dish’s elegance without overpowering it. 🍷
Beer Pairings
An American pale ale, like Allagash White, with its citrusy hops and light body, cleanses the palate between bites. For a darker option, try a Belgian dubbel—such as Westmalle Dubbel—which adds a malty depth that stands up to the pork’s richness. 🍺
Garnish Finishing Touches
Drizzle the sliced pork with honey and balsamic glaze just before serving for a sweet-tangy contrast. A sprinkle of toasted sesame seeds or fresh thyme adds a final aromatic touch. I also love a dusting of flaky sea salt for a sophisticated finish. ✨

Frequently asked questions
Why does this recipe use the reverse-sear method instead of traditional roasting?
The reverse-sear technique ensures perfectly cooked pork every time by cooking the meat slowly first to reach 140°F internally, then finishing with a high-heat sear for a crisp crust. This eliminates the risk of overcooking the exterior while the center cooks, which is especially important for thick cuts like pork loin. Traditional roasting often results in dry edges while the center remains undercooked.
Can I substitute bone-in pork loin for boneless?
Yes, but adjust your expectations slightly. Bone-in pork loin has better heat conduction and stays more moist during cooking. If using boneless, reduce the oven temperature by 10°F (to 265°F) and monitor closely—it may need 5-10 minutes less time. The bone also adds natural flavor during searing.
What if I don't have a meat thermometer?
You can still achieve great results! Press the pork gently with your finger—when it feels slightly springy (like pressing a firm mattress) and the juices run clear, it's ready. For visual cues, look for a golden-brown crust and slightly pulled edges. The internal temperature should be 140°F when done.
How far ahead can I prepare the seasoning mix? Prepare the herb-salt mixture up to 3 days ahead and store it in an airtight container in the fridge. The flavors meld beautifully, and it saves time on cooking day. Just
What's the best way to reheat leftover pork loin?
Slice the pork and reheat in a 350°F oven for 10-15 minutes wrapped in foil with a splash of water or broth. This prevents drying out. For quick reheating, use a skillet over medium heat with 1 tablespoon butter for 2-3 minutes per side**. Never microwave—it ruins the texture.
