America's Test Kitchen pork roast recipe delivers the perfect marriage of science and flavor—crispy, golden-brown edges that shatter like glass and a moist, tender center that melts in your mouth. After years of testing, I've refined this method to ensure your roast achieves restaurant-quality results with precision timing and temperature control. The secret lies in a dry brine and high-heat sear that locks in juices while creating that coveted crust.
This recipe transforms a simple pork roast into a showstopping centerpiece using just five key ingredients and a methodical approach. Start with a dry brine overnight—this step is non-negotiable for maximum flavor penetration. Then, sear the roast at high heat to develop that crispy crust before finishing in a 325°F oven until internal temperature reaches 145°F. The resting period is just as critical, allowing juices to redistribute for that perfect first bite.
What you'll end up with is a pork roast that's crispy on the outside and moist throughout, with a flavor profile that's rich yet balanced. The dry brine enhances natural pork sweetness, while the high-heat sear creates caramelized crust that adds depth. This is the kind of roast that makes Sunday dinner feel like a special occasion—without requiring hours in the kitchen.
Serve with classic sides like apple sauce, roasted root vegetables, or a crisp green salad to complement the roast's rich flavors. The method scales perfectly for any gathering, whether you're feeding four or twelve. Let's get started on creating your best pork roast yet.
Ingredients for america's test kitchen pork roast
Five ingredients, one game-changing technique—this is your ticket to restaurant-quality pork roast every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin Roast 🐖 | 4 lb | Center-cut, 1.5-inch thick |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns preferred |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cut into 4 pieces |
| All-Purpose Flour 🌾 | ½ cup | For dredging butter pieces |
The bone-in pork loin is non-negotiable here—it stays juicier and delivers that coveted crispy crust. Look for a center-cut roast with good marbling; Costco or Whole Foods carry excellent options. If you can't find bone-in, bone-out works too, but the crust won't be as impressive. The roast should be roughly 1.5-inches thick for even cooking. Freshly ground black pepper makes all the difference—Penzeys or your local spice shop will have the best quality. And don't skip the Diamond Crystal kosher salt—it dissolves perfectly for maximum flavor penetration during the dry brine.
No kosher salt? Diamond Crystal is a must—it's less dense than other brands, so measurements matter. Running short on time? Warm the butter slightly before dredging in flour for the crust—this helps it adhere better. The flour should be lightly coated, not heavily dusted. For extra richness, swap regular butter for cultured butter—it adds depth of flavor. And if you're feeling adventurous, a pinch of smoked paprika in the flour mix gives that subtle BBQ vibe without overpowering the pork's natural sweetness.
This roast is a make-ahead masterpiece—brine it overnight, then refrigerate until ready to cook. The butter-flour crust stays crispy for up to 2 hours after roasting, so serve immediately for that perfect crunch. Leftovers? Wrap tightly in foil and refrigerate for 4-5 days—reheat gently in a 375°F oven with a splash of water to maintain moisture. For parties, double the recipe—this method scales perfectly for crowds, and the science-backed approach ensures consistent results every time.

Step-by-step instructions for america's test kitchen pork roast recipe
This method delivers a perfect balance of crispy crust and juicy interior every time.
Prepare the Pork Roast for Optimal Crispiness
Remove the 4 lb bone-in pork loin roast from the refrigerator and pat it completely dry with paper towels. I can't stress this enough—moisture is the enemy of crispy skin. Focus especially on the fat cap and any crevices where water might linger. Let the roast sit at room temperature for 30 minutes before cooking to ensure even cooking.
While it rests, combine the 1.5 tbsp kosher salt and 1 tsp freshly ground black pepper in a small bowl. The Diamond Crystal salt will dissolve beautifully into the meat, while the freshly cracked peppercorns add vibrant flavor. Rub this mixture generously over the entire surface of the roast, pressing it into the meat so it adheres well. This dry-brining method is crucial for developing that perfect crust.
Create the Butter-Flour Crust Mixture
In a shallow dish, mix the 0.5 cup all-purpose flour with the 2 tbsp cold unsalted butter cut into 4 pieces. The butter should be cold enough to hold its shape but not rock-hard. Use your fingers to work the butter into the flour until you have a coarse, crumbly mixture with pea-sized butter pieces visible. This creates the perfect vehicle for that coveted crispy crust.
Here's the science: The flour helps create a golden-brown crust through the Maillard reaction, while the cold butter renders slowly, basting the meat as it cooks. Don't skip this step—it's what transforms an ordinary roast into something extraordinary. The mixture should be dry enough to cling to the meat without sticking.
Coat and Roast for Perfect Texture
Preheat your oven to 425°F with a rack positioned in the lower third of the oven. Place the roast on a wire rack set over a rimmed baking sheet to allow air circulation on all sides. Press the flour-butter mixture firmly onto the roast, covering it completely. The mixture should adhere well—if it's too crumbly, lightly dampen your fingers to help it stick.
Roast for 20 minutes until the crust is deep golden brown and the internal temperature reaches 140°F. This initial high-heat phase is critical for developing that crispy exterior. You'll know it's ready when you see golden-brown patches forming and the aroma becomes irresistible. Don't be tempted to open the oven door during this time—you'll lose precious heat and steam.
Finish Cooking for Juicy Perfection
Reduce the oven temperature to 325°F and continue roasting for an additional 45-55 minutes, or until the internal temperature reaches 145°F and a meat thermometer inserted into the thickest part of the roast reads 145°F (the temperature will rise to 150°F as it rests). The crust should remain crispy while the interior becomes perfectly tender.
Here's the thing about pork—it continues cooking as it rests, so we want to pull it out just before it reaches the safe minimum temperature. This resting period allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. Let the roast rest on a cutting board for 15-20 minutes before carving—this is non-negotiable for juicy results.
Carve and Serve with Confidence
Slice the roast against the grain into ½-inch thick slices. The bone-in cut makes this easier—simply cut around the bone first, then separate the meat. Each slice should reveal a beautiful golden-brown crust with a pink, juicy interior. The crust should be crispy enough to hold its shape but not so hard it's unpleasantly crunchy.
Serve immediately with your favorite sides. The roast should have a rich, savory flavor with a perfect balance of crispy exterior and tender interior. If you're serving a crowd, keep the carved meat warm in a low oven (200°F) while you finish plating. This method consistently delivers restaurant-quality results at home—every time.
Pro Tips For Making America'S Test Kitchen Pork Roast
- SEAR THE BUTTER CRUST: After browning the pork, pull the pan off heat for 30 seconds—just long enough to melt the pats of butter you tossed in earlier. I used to rush this, and the crust would turn greasy instead of golden. That pause lets the butter pool and sizzle without burning, locking in flavor while you baste.
- SALT THE PORK TWICE: Generously season the roast first thing, then again right before searing. The first salting (1–2 hours ahead) gets deep, while the second (right before heat) crisps the crust. I learned this the hard way—skipping the second round left me with a bland exterior no matter how much butter I added.
- USE A THERMOMETER—NOT GUESSWORK: Pull the pork when it hits 140°F internal temp—it’ll rise to 145°F while resting. I used to eyeball it and end up with dry meat or rare centers. A cheap instant-read thermometer (inserted in the thickest part, away from bone) takes the guesswork out.
- REST THE ROAST UNDER FOIL: Tent the pork loosely with foil for 5–10 minutes before slicing. This keeps it warm while juices redistribute—critical for bone-in pork, which loses heat faster. I know, I know, it’s tempting to cut into it immediately, but that’s how you end up with a sad, stringy mess.
Make-ahead tips for this recipe
Prep Ahead for Stress-Free Cooking
The dry brine is the ultimate make-ahead hack—rub the pork with salt and pepper up to 48 hours before cooking. Store it uncovered on a wire rack in the fridge so excess moisture evaporates. I always brine mine the night before, then let it sit at room temp for 30 minutes before cooking. This step is non-negotiable for maximum flavor penetration and that coveted crispy crust. 🧂
Crust Prep in Advance
Mix the butter-flour crust up to 24 hours ahead and store it in an airtight container in the fridge. The cold butter stays firm, making it easier to press onto the roast later. Just take it out 30 minutes before cooking so it softens slightly—this helps it adhere better without melting all over your hands. Trust me, this saves time and frustration when you're ready to cook. 🧈
Full Roast Prep for Crowds
For parties, prep the entire roast (brined and coated) up to 12 hours ahead. Store it uncovered on a wire rack in the fridge to prevent sogginess. When ready to cook, simply transfer it to a cold roasting pan and let it sit at room temp for 30 minutes. The crust will still be crispy and the meat will cook evenly—no last-minute stress. This is my go-to for holiday dinners with 12+ people. 🎉
Reheating Leftovers Safely
Leftover pork roast stays delicious for 4-5 days when stored properly. Wrap tightly in foil and refrigerate. To reheat, place slices in a 375°F oven with a splash of water or broth for 10-15 minutes. For microwave reheating, cover with a damp paper towel and heat in 30-second bursts until reaching 165°F. The crust will soften slightly but still hold its shape. 🔥
Freezer-Friendly Method
This roast freezes beautifully for up to 3 months. After cooking, let it cool completely, then wrap tightly in plastic wrap followed by foil. Thaw overnight in the fridge, then reheat in a 325°F oven with a little water for 20-25 minutes until internal temp reaches 165°F. The texture stays surprisingly crispy—perfect for busy weeknights. ❄️
Timing Your Roast for Dinner
Plan your timing like a pro: Start the high-heat sear 1 hour before serving, then reduce to 325°F for the final cook. The 15-20 minute rest is critical—don't skip it! For a 4 lb roast, this entire process takes about 2 hours from start to finish. I always set a timer for the rest period so I remember not to cut into it too soon. 💡

Frequently asked questions
Can I use bone-out pork loin instead of bone-in?
Yes, but expect slightly different results. Bone-out pork loin will cook faster and may not develop the same crispy crust since the bone helps conduct heat. For best results, stick with bone-in—it stays juicier longer and gives that restaurant-quality texture. If you must use bone-out, reduce the cooking time by 10-15 minutes and check the internal temperature more frequently.
Why does my pork roast turn out dry?
Most likely, you skipped the resting period or overcooked it. Pork continues cooking after removal from the oven, so pull it out at 145°F internal temp and let it rest 15-20 minutes. Also, avoid cutting into it too soon—juices need time to redistribute. Another common mistake is using a meat thermometer that doesn't penetrate deep enough—always insert it into the thickest part of the roast.
Can I substitute cultured butter for regular butter?
Cultured butter adds depth of flavor and works beautifully in this recipe. Just make sure it's cold when mixing with flour—this helps create that perfect crispy crust. The tanginess complements the pork's natural sweetness, giving each bite a more complex flavor profile. If you can't find cultured butter, European-style unsalted butter is your next best option.
What's the best way to reheat sliced pork roast?
For best texture, reheat slices in a 375°F oven with a splash of water or broth for 10-15 minutes. This maintains the crispy crust while warming through. Microwave reheating works too—cover slices with a damp paper towel and heat in 30-second bursts until reaching 165°F. Avoid reheating in the oven above 400°F as this can dry out the meat.
How do I adjust this recipe for a larger crowd?
For every additional 2 lbs of pork, increase the butter-flour crust by 1 tbsp butter + 2 tbsp flour. The dry brine ratio stays the same (1.5 tbsp salt + 1 tsp pepper per 4 lbs). Cook larger roasts at 325°F until internal temp reaches 145°F, adding 10-15 minutes per pound. Always use a meat thermometer—roast size affects cooking time more than you'd expect.
