Ingredients for america's test kitchen pork roast
Precision-cut pork, a science-backed brine, and exacting seasoning transform tough cuts into melt-in-your-mouth perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin Roast 🥓 | 4 lb | Center-cut, 1.5-inch thick |
| Diamond Crystal Kosher Salt 🧂 | 1 cup | For brine solution |
| Cold Water 💧 | 4 cups | For brine preparation |
| Fresh Garlic Cloves 🧄 | 6 cloves | Minced for seasoning |
| Fresh Thyme Sprigs 🌿 | 4 whole | Leaves only, stems removed |
| Ground Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For finishing crust |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for crust |
| Meat Thermometer 📊 | 1 whole | Instant-read preferred |
| Apple Cider Vinegar 🍎 | 1 tbsp | For brine acidity |
| Brown Sugar 🍬 | 1 tbsp | Light, for crust enhancement |
The bone-in pork loin roast is non-negotiable for this recipe—center-cut ensures even cooking while the bone adds flavor. Whole Foods or high-end butchers carry the best quality, but any reputable grocery store's meat department should have suitable options. Look for even marbling and a pink, vibrant color—avoid any cuts with grayish hues or excessive fat. For a foolproof experience, purchase the roast 1-2 days ahead to allow for proper brining. The 1.5-inch thickness is critical for achieving that perfect balance of crisp exterior and tender interior without overcooking.
No Diamond Crystal kosher salt? Morton kosher salt works identically, but measure carefully—it's slightly denser. Fresh thyme is ideal, but dried thyme at one-third the amount suffices in a pinch (though fresh delivers superior aroma). For the brine solution, the apple cider vinegar adds subtle tang—substitute lemon juice if unavailable. The olive oil should be extra-virgin for optimal flavor infusion during the high-heat finish. If using a pre-made rub, ensure it contains no added sugar beyond the brown sugar specified here to maintain proper crust development. The meat thermometer is mandatory; instant-read models like those from Thermoworks provide the most accurate results during the critical doneness check.
Prepare the brine 24 hours ahead for maximum moisture retention, storing it in the refrigerator. The roast should rest 15 minutes post-roasting—this critical step prevents juices from pooling, ensuring every slice remains succulent. For long-term storage, portion the cooked pork into airtight containers with a thin layer of olive oil to preserve moisture; it keeps for 4-5 days in the fridge or 3 months frozen. The thyme sprigs can be composted after use, and any leftover kosher salt should be stored in a dry, airtight container for up to 12 months. The brown sugar remains stable indefinitely in a cool, dark pantry.

Step-by-step instructions for america's Test Kitchen pork roast
This method delivers restaurant-quality pork without drying it out—science-backed precision every time.
Prepare the Brine Solution
In a large bowl, combine the 4 cups cold water, 1 cup Diamond Crystal kosher salt, and 1 tablespoon apple cider vinegar. Stir until the salt fully dissolves—this creates an even brine that ensures perfect moisture distribution throughout the roast. The acidity from the vinegar also helps tenderize the meat slightly.
Place the 4 lb bone-in pork loin roast in a large resealable plastic bag or container that can hold the brine. Pour the brine solution over the roast, ensuring it's fully submerged. Seal the bag or cover the container and refrigerate for 12 to 24 hours. This long brine time guarantees the pork remains juicy even after high-heat roasting. If using a container, weigh down the roast with a plate to keep it fully immersed.
Season and Rest the Roast
Remove the roast from the brine and rinse it thoroughly under cold water to remove excess salt. Pat it dry with paper towels—this step is critical for developing a crispy crust later. In a small bowl, combine the 6 cloves minced fresh garlic cloves, 1 tablespoon ground black peppercorns, and the leaves from 4 whole fresh thyme sprigs. Rub this mixture all over the roast, pressing it into the meat to ensure even flavor penetration.
Let the seasoned roast rest at room temperature for 30 minutes before roasting. This step allows the meat to cook more evenly, preventing a cold center. While it rests, preheat your oven to 325°F. The lower temperature ensures gentle, even cooking without overbrowning the exterior.
Roast with Precision
Place the roast on a rack set inside a roasting pan, fat-side up. This positioning allows heat to circulate around the meat, promoting even cooking. Roast for 1 hour and 45 minutes until the internal temperature reaches 145°F at the thickest part of the roast. Use the meat thermometer to monitor—insert it into the thickest part of the meat without touching bone.
During the last 30 minutes of roasting, increase the oven temperature to 425°F. This final high-heat phase creates a golden-brown crust while keeping the interior juicy. The roast is done when the thermometer reads 145°F and the juices run clear when pierced with a knife. Remove it from the oven and let it rest for 20 minutes before carving—this resting period allows the juices to redistribute, ensuring every slice stays moist.
Create the Crust and Finish
While the roast rests, melt the 2 tablespoons unsalted butter in a small saucepan over low heat. Remove it from heat and stir in the 2 tablespoons extra-virgin olive oil and 1 tablespoon brown sugar until fully combined. Brush this mixture generously over the roast, focusing on the top and sides. The sugar and butter create a caramelized crust that adds depth of flavor and texture.
Slice the roast against the grain into ½-inch thick portions and serve immediately. The exterior should be golden and crisp, while the interior remains tender and juicy. This method ensures a perfect balance of texture and flavor, with no risk of overcooking.
Pro Tips For Making America'S Test Kitchen Pork Roast
- USE A THERMOMETER: The ATK pork roast recipe is all about hitting 140°F internally—no guessing. I learned this the hard way by pulling a roast that looked "done" but was still tough. A cheap instant-read thermometer is worth its weight in juicy slices.
- PEEL AND SMASH THE GARLIC: Whole garlic cloves won’t infuse the pork like you’d hope. Peel them, smash with the flat side of your knife, and let them sit on the roast for 30 minutes before cooking. It’s more work upfront, but the flavor difference is noticeable—especially when you’re serving guests who notice these things.
- DON’T SKIP THE COLD WATER BRINE: The recipe calls for a 40-minute brine in cold water and salt—don’t skip it. I used to think it was overkill, but that step keeps the pork juicy even when roasted to 140°F. Just make sure the roast is fully submerged, or you’ll end up with dry edges.
- REST IT UNDER FOIL: Pull the pork at 140°F and tent it loosely with foil for 15 minutes before carving. I know, I know—you’re eager to cut into it. But skipping this step means losing all that rendered juice to the cutting board. Trust me, your guests won’t even notice the wait.
Best sauces and condiments for these flavors
Classic Apple Cider Glaze
This tangy-sweet glaze elevates your pork roast with minimal effort. Simmer ½ cup apple cider, 2 tbsp brown sugar, and 1 tbsp Dijon mustard in a small saucepan until reduced by half (5-7 minutes).
Brush generously over the roast during the final 15 minutes of roasting. The acidity cuts through the richness while caramelizing beautifully. 🍎
Herb Butter Compound
For a restaurant-worthy finish, blend ½ cup softened unsalted butter with 2 tbsp chopped fresh rosemary, 1 tbsp chopped parsley, 1 minced garlic clove, and ½ tsp salt. Spread this mixture over the roast during the last 30 minutes of cooking.
The herbs infuse the butter, creating a fragrant crust that melts into every bite. I use this technique for holiday dinners—it’s a crowd-pleaser every time.
Spiced Mustard Cream Sauce
Whisk together ½ cup sour cream, 2 tbsp whole-grain mustard, 1 tbsp honey, and 1 tsp smoked paprika for a creamy, slightly tangy sauce. Serve it warm alongside sliced pork, drizzled over roasted potatoes, or used as a dipping sauce.
The smoky paprika adds depth without overpowering the pork’s natural flavor. 🌶️
Brown Sugar-Balsamic Reduction
Combine ¼ cup balsamic vinegar, 2 tbsp brown sugar, and 1 tbsp olive oil in a saucepan. Simmer until thickened (8-10 minutes), then reduce heat and add 1 tsp Dijon mustard.
Pour over sliced pork or use as a pan sauce. The balance of sweet, tangy, and umami makes this a versatile topping for any pork dish.
Honey-Garlic Pan Sauce
After roasting, deglaze the pan with ¼ cup chicken broth and scrape up browned bits. Add 2 tbsp honey, 1 tbsp soy sauce, and 1 minced garlic clove, then simmer for 3-4 minutes until slightly thickened.
Drizzle over sliced pork or use as a glaze for extra shine. This sauce pairs perfectly with the herb butter technique for a double flavor punch.
Creamy Horseradish Sauce
Mix ½ cup sour cream, 2 tbsp prepared horseradish cream, 1 tbsp chopped chives, and ½ tsp black pepper for a sharp, creamy condiment.
Serve chilled alongside sliced pork—it cuts through the richness and adds a refreshing kick. I keep this in my fridge year-round for quick servings.

Frequently asked questions
Can I use a different cut of pork for this recipe?
This recipe is specifically designed for bone-in pork loin roast because of its ideal fat-to-lean ratio and even cooking properties. For similar results, you could try a bone-in pork shoulder, but it will require longer cooking times (3-4 hours at 275°F) and a different seasoning approach. Pork tenderloin is too lean and will dry out using this method.
How do I know when the pork is fully cooked without overcooking?
Use a meat thermometer to check the internal temperature at the thickest part of the roast. It should reach 145°F—this is the USDA-recommended safe minimum. The thermometer should read 145°F while the roast is still in the oven, not after resting. For pork loin, this ensures perfect doneness without drying out.
Can I make this roast ahead of time?
Yes! Cook the roast as directed, then let it cool completely. Store it in an airtight container with a thin layer of olive oil to preserve moisture. Reheat slices in a 375°F oven for 10-15 minutes or until warmed through. The texture will be slightly less crisp, but the flavor remains excellent.
Why does my pork come out dry even when following the recipe?
Dry pork usually results from overcooking or not using a thermometer. Always remove the roast when it hits 145°F—don't guess! Another common mistake is skipping the resting time (20 minutes). Juices need time to redistribute. Also ensure your roast isn't too thick (stick to 1.5-inch thickness), as thicker cuts require longer cooking.
What are the best sides to serve with this pork roast?
Classic pairings include garlic mashed potatoes, roasted root vegetables, or apple cider braised cabbage. For a lighter option, try sautéed green beans with almonds. The crispy skin and rich flavor of the pork work beautifully with tangy or creamy sides that cut through the richness. A simple green salad with vinaigrette also balances the meal perfectly.
