America's Test Kitchen Pork Loin Recipe: Sear-and-Roast Precision for Foolproof Results

This America's Test Kitchen pork loin recipe delivers restaurant-quality results with foolproof sear-and-roast precision—no guesswork, just perfect meat every time. After years of testing, we've cracked the code for achieving juicy, tender pork with a crispy, caramelized crust, using a method that's both scientific and simple. The secret lies in the 325°F (163°C) roast paired with a high-heat sear, ensuring even cooking and maximum flavor extraction. What sets this recipe apart is the two-step process: first, a dry brine (salt the pork 24 hours ahead) to enhance moisture retention, then a hot sear in a cast-iron skillet before transferring to the oven. This technique guarantees a golden-brown exterior while keeping the interior tender and moist—no dry, overcooked pork here. The recipe also includes a pan sauce made from the rendered pork drippings, adding depth and richness without extra effort. By following these exact steps, you'll end up with perfectly cooked pork loin that slices easily and stays juicy, even when reheated. The crispy edges and tender centers make this ideal for family dinners or special occasions, where presentation matters as much as taste. Serve with roasted apples, mashed potatoes, or a simple green salad for a complete meal that impresses every time. For those who love precision in the kitchen, this method delivers consistent, reliable results—no more worrying about overcooking or uneven doneness. The scientific approach ensures success, whether you're a home cook or a seasoned pro. Let's get started on creating pork loin that rivals your favorite restaurant.

Precision-crafted ingredients for restaurant-quality pork loin with foolproof sear-and-roast technique.

The bone-in pork loin is non-negotiable for optimal moisture and flavor—center-cut pieces with visible fat cap ensure even cooking. For sourcing, Whole Foods or local butcher shops offer superior quality, but most grocery stores carry adequate options. Look for bright red color and firm texture when selecting your roast. The thickness (1.5 inches) is critical for proper searing and doneness. If your butcher doesn't cut it to spec, request it—this isn't something you want to compromise on. Diamond Crystal kosher salt is preferred for its coarse texture, which adheres better to the meat surface during dry brining.

No fresh herbs? Dried thyme and rosemary work at one-third the amount, but fresh delivers superior aroma and flavor. The white wine can be swapped for apple cider vinegar in a pinch, though the acidity will alter the sauce's balance slightly. For the stock, ensure it's low-sodium—high-sodium versions can overpower the delicate pork flavors. The olive oil should have a high smoke point (look for 'light' or 'refined' labels) to prevent burning during the sear. Prefer Sauvignon Blanc for its crisp acidity, but any dry white will suffice. If using chicken stock, opt for homemade or high-quality store-bought to avoid artificial flavors.

The dry-brined pork should rest uncovered in the fridge for 24 hours—this is non-negotiable for moisture retention. Store butter and flour in airtight containers at room temperature, while fresh herbs last 5-7 days wrapped in damp paper towels. The wine and stock can be refrigerated for up to 1 week post-opening, though the sauce is best made fresh. For long-term storage, freeze the pan sauce in ice cube trays for 3 months. The pork loin can be prepped ahead but should be seared and roasted the same day for optimal texture.

Step-by-step instructions for america's Test Kitchen pork loin

Master the sear-and-roast technique for a perfectly cooked pork loin with crisp edges and juicy center.

Remove the pork loin from the refrigerator and pat it dry thoroughly with paper towels. This step is critical—any moisture on the surface will prevent proper browning. Place the roast 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 tablespoons kosher salt and 1 teaspoon freshly ground black pepper. Generously rub this mixture all over the pork loin, including the cut sides. Let it sit at room temperature for 30 minutes before cooking. This resting period ensures even cooking and better seasoning penetration.

Preheat your oven to 425°F. Heat a large oven-safe skillet over medium-high heat until it's very hot. Add the 1 tablespoon extra-virgin olive oil and swirl to coat the bottom evenly. Place the pork loin fat-side down in the skillet and sear for 8-10 minutes, pressing down gently with a spatula to ensure full contact with the pan. You'll see the fat render and the skin develop a deep golden-brown crust.

Flip the pork loin and continue searing for another 6-8 minutes until the second side is equally browned. The searing step is what creates that restaurant-quality crust and locks in juices. Transfer the skillet to the preheated oven and roast for 20-25 minutes, or until the internal temperature reaches 145°F when measured with a meat thermometer in the thickest part of the loin.

While the pork loin roasts, prepare the sauce components. In a small bowl, combine the 2 tablespoons unsalted butter (cut into 4 pieces) with the 1 tablespoon all-purpose flour. This mixture will create a velvety sauce later. Thinly slice the 1 whole yellow onion and mince the 4 cloves garlic. Chop the 1 tablespoon fresh thyme leaves and 1 teaspoon fresh rosemary finely.

In a separate small bowl, whisk together the 0.5 cup dry white wine and 0.5 cup chicken or vegetable stock. This liquid will form the base of your pan sauce, so keep it nearby for quick assembly.

Remove the pork loin from the oven and transfer it to a cutting board. Tent loosely with foil and let it rest for 10-15 minutes—this resting period is essential for redistributing juices throughout the meat.

Return the skillet to the stovetop over medium heat. Add the sliced onion and cook for 3-4 minutes until softened. Add the minced garlic, thyme, and rosemary, cooking for another 30 seconds until fragrant. Immediately pour in the wine-stock mixture and bring to a gentle simmer, scraping up any browned bits from the bottom of the pan with a wooden spoon.

Add the butter-flour mixture to the skillet and whisk vigorously until the butter melts and the sauce thickens, about 1-2 minutes. The sauce should coat the back of a spoon and cling beautifully to the pork. Season with additional salt and pepper if needed.

Slice the pork loin into ½-inch thick medallions against the grain. Spoon the pan sauce over the top and garnish with the 2 tablespoons chopped fresh parsley. Serve immediately with roasted vegetables or mashed potatoes for a complete meal. The result should be a perfectly cooked pork loin with a crisp exterior, juicy interior, and rich, flavorful sauce.

Storing and reheating this america's test kitchen pork loin

Refrigerator Storage

After cooking, let your pork loin rest for 15 minutes before slicing—this ensures juices redistribute. Store leftovers in an airtight container with a tight-sealing lid, like Glasslock containers, for up to 4 days. I always cover the meat with a damp paper towel to prevent drying out. For best results, refrigerate within 2 hours of cooking to maintain freshness. 💫

Freezer Prep Tips

For long-term storage, slice the pork loin into ½-inch medallions before freezing. Place them in a single layer on a baking sheet, then transfer to a freezer-safe bag with all air removed. Label with the date—this pork stays tender for up to 3 months. When ready to reheat, thaw overnight in the fridge for even cooking.

Stovetop Reheating

My preferred method is reheating in a skillet over medium-low heat with 1 tablespoon butter or olive oil. Add 2 tablespoons water or stock to prevent drying, then cover and heat for 5-7 minutes, stirring occasionally. The sauce will help revive the meat's moisture and flavor. For extra crispiness, sear the slices for 1 minute per side after reheating. 🔥

Oven Refresh Method

Preheat your oven to 325°F and place sliced pork loin on a baking sheet with 1 tablespoon pan sauce. Cover loosely with foil and bake for 10-12 minutes, stirring halfway. This gentle heat keeps the meat tender without overcooking. I often add a splash of stock to maintain juiciness during reheating.
