America's Test Kitchen Pork Roast Recipe: Precision-Cooked Medium-Rare Core

Precision matters when you're cooking a pork roast—and this America's Test Kitchen-inspired method delivers a juicy, medium-rare core with crispy edges every time. I've spent years perfecting the technique, from the perfect brine to the exact internal temperature, ensuring restaurant-quality results at home.

The secret? A two-stage roast that locks in moisture while building flavor through the crust.

This recipe starts with a dry brine that enhances tenderness and flavor penetration, followed by a high-heat sear to develop that coveted caramelized bark. We'll use a meat thermometer for foolproof doneness—no guessing—so you achieve that perfect medium-rare center (140°F) while keeping the exterior golden and crisp.

The resting period is just as critical; skipping it means losing precious juices.

What you'll end up with is a showstopping roast that slices beautifully and tastes even better—rich, savory, and perfectly balanced between tender meat and crisp edges. The technique works for bone-in or boneless cuts, and the same method applies to other large roasts like beef or lamb.

This is the kind of dish that makes dinner feel special without requiring hours of effort.

Pair it with a simple apple-cider pan sauce or roasted root vegetables to complete the meal. The precision in this method means you can confidently cook pork to your exact preference, whether you love it medium-rare, medium, or well-done.

Let's get started on a roast that'll impress even the most discerning guests.

Ingredients for america's test kitchen pork roast

Six ingredients transform into a showstopping pork roast with restaurant-quality precision.

The pork cut matters most here—bone-in pork loin delivers that perfect balance of flavor and moisture. Look for a center-cut roast with visible marbling (that white fat streaking through the meat) for maximum tenderness. Whole Foods or your local butcher shop will have the best quality, but any reputable grocery store's meat counter should carry it. If you're buying frozen, thaw it in the fridge for 24 hours—never at room temperature. The dry brine (salt and sugar) is non-negotiable; it's what creates that tender, juicy core while developing that crisp exterior. I always double-check the thickness—1.5-2 inches is ideal for even cooking.

No fresh thyme or rosemary? Dried works at one-third the amount, but fresh has that unmatched aroma. Running short on apple cider vinegar? White vinegar or lemon juice in a pinch, though the flavor will differ slightly. The olive oil should be extra-virgin—anything less lacks the fruity depth needed for that perfect crust. For the pan sauce, if you can't find apple cider, dry white wine or chicken stock works beautifully. And trust me on the cold butter cubes—adding them at the end creates that luxurious finish without breaking the sauce. Pre-ground pepper loses potency fast, so invest in a pepper grinder if you don't have one.

This roast reheats beautifully—350°F for 15 minutes with a splash of water keeps it juicy. The pan sauce? Make it ahead and reheat gently over low heat. Store the roast wrapped in parchment in the fridge for up to 4 days or freeze for 3 months. I always portion the sauce separately so it doesn't get soggy. For leftovers, slice thinly and reheat with a splash of water or broth. The crust will soften slightly, but the meat stays incredibly tender—perfect for sandwiches or salads the next day.

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

Here's the method that delivers juicy, medium-rare pork with perfect crust every time.

Remove the pork loin roast from the refrigerator and let it sit at room temperature for 30 minutes before cooking. This ensures even cooking throughout. Pat the roast dry with paper towels—this step is crucial for developing that beautiful crust. I like to use two thick paper towels to get it completely dry, especially in the crevices where moisture can hide.

In a small bowl, combine the 1.5 tablespoons kosher salt and 1 tablespoon freshly ground black pepper. Rub this mixture all over the roast, pressing firmly to ensure the seasoning adheres. The salt will penetrate the meat while it rests, creating a flavorful crust. Let the seasoned roast rest uncovered on a wire rack set over a baking sheet for another 15 minutes—this final rest helps the seasoning stick and prevents steam buildup during cooking.

Preheat your oven to 425°F. Heat a large oven-safe skillet over medium-high heat until it's very hot. Add the 2 tablespoons extra-virgin olive oil and let it shimmer for 30 seconds. Place the pork roast in the skillet, fat-side down, and sear for 4-5 minutes until the fat is golden brown and crispy. Flip the roast and sear the other side for another 4-5 minutes.

Here's the thing—don't rush this step. You want deep color development on the exterior, which locks in flavor. If the skillet isn't hot enough, the oil will smoke excessively. If that happens, reduce the heat slightly and let it recover before continuing. The goal is a rich, caramelized crust that will carry through to your finished roast.

Transfer the skillet to the preheated oven and roast the pork for 20-25 minutes for a 4-pound roast. The internal temperature should reach 130°F when measured with a meat thermometer inserted into the thickest part of the roast. This is the sweet spot for medium-rare pork—juicy, tender, and with a perfect pink center.

Real talk: Your oven might run hot or cold, so I recommend checking the temperature at the 20-minute mark. If it's cooking faster than expected, you might need to reduce the oven temperature by 25°F for the remaining time. The key is patience—pork continues cooking after you remove it from the oven, so don't overcook it in an attempt to hit the exact temperature.

While the roast rests, remove it from the skillet and place it on a cutting board. Tent loosely with foil. Pour out all but 1 tablespoon of the rendered fat from the skillet. Return the skillet to the stovetop over medium heat and add the 8 smashed garlic cloves, 4 thyme sprigs, and 4 rosemary sprigs. Sauté for 1 minute until fragrant.

Add the 2 tablespoons apple cider vinegar and 1 teaspoon granulated sugar, scraping up any browned bits from the bottom of the skillet. Let it simmer for 2 minutes until slightly reduced. Pour in the 0.5 cup apple cider and 0.5 cup heavy cream, then stir in the 1 teaspoon Dijon mustard. Simmer for another 3-4 minutes until the sauce thickens slightly and coats the back of a spoon. If it's too thick, add a splash of water to reach your desired consistency.

Let the roast rest for 15 minutes before slicing. This resting period is non-negotiable—it allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. During this time, keep the skillet warm over low heat to maintain the sauce's temperature.

Slice the pork roast into ½-inch thick slices against the grain for maximum tenderness. Spoon the apple cider pan sauce over the top and serve immediately. The roast should be juicy with a beautiful pink center, and the sauce should coat each slice with a balance of sweet, tangy, and herby flavors. This method guarantees a restaurant-quality pork roast you'll be proud to serve.

Storing and reheating your leftovers

Refrigerator Storage

After cooking, let your pork roast cool to room temperature for no more than 2 hours before storing. Wrap it tightly in parchment paper (not plastic—it traps moisture and turns the crust soggy) and place it in an airtight container or resealable plastic bag.

Store in the fridge at 40°F or below for up to 4 days. The flavors actually deepen overnight as the meat continues to rest, making leftovers even more delicious. 🥗

I always slice any leftover roast into ½-inch thick pieces before storing—this makes reheating faster and more even. Keep the pan sauce separate in a small container to prevent it from absorbing the meat’s moisture. When reheating, add a splash of water or broth to maintain juiciness.

Freezer Storage

For longer storage, freeze the roast for up to 3 months for peak quality. Wrap it in butcher paper first (to protect against freezer burn), then place it in a heavy-duty freezer bag or airtight container.

Label with the date—this roast freezes beautifully while retaining its texture and flavor. When ready to reheat, thaw it in the fridge overnight for the best results. ❄️

Pro tip: Freeze the roast in single-serving portions if you plan to reheat it gradually. This way, you only thaw what you need, minimizing waste. I’ve found that pre-slicing before freezing also speeds up the reheating process—just add a splash of water or apple cider to the pan when reheating.

Reheating Methods

For the best texture, reheat sliced pork roast in a skillet over medium heat for 5-7 minutes, adding 1-2 tablespoons of water or apple cider to keep it moist.

Cover the skillet with a lid to trap steam and prevent drying. This method preserves the crispness of the crust while ensuring the meat stays tender. 🔥

If you’re short on time, the microwave works in a pinch—just place the slices on a plate, cover with a damp paper towel, and heat on 50% power for 1-2 minutes.

Stir halfway through to ensure even heating. For the pan sauce, reheat it separately over low heat, stirring constantly to prevent scorching.

Reviving the Crust

If your reheated roast loses some of its crispy edges, don’t worry—you can restore it with a quick broiler finish. Place the slices on a baking sheet and broil for 1-2 minutes until the edges turn golden again.

This works especially well if you’re serving it as a sandwich or platter. 💫

For extra flavor, brush the reheated slices with a little melted butter or a splash of apple cider before serving. The acidity helps brighten the meat, making it taste almost as good as fresh. Trust me, this trick saves leftovers from feeling like a sad, dry afterthought.
