Ingredients for america's test kitchen pork belly
Four pounds of pork belly and a handful of simple ingredients transform into a showstopping centerpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly (skin-on) 🥓 | 4 lb | Thick-cut, skin left intact |
| Kosher Salt 🧂 | ½ cup | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked for depth |
| Fresh Rosemary 🌿 | ¼ cup | Chopped sprigs, not dried |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems removed |
| Garlic Cloves 🧄 | 6 cloves | Smash lightly, skin-on |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity |
| Brown Sugar 🍚 | 2 tbsp | Lightly packed |
| Unsalted Butter 🧈 | 4 tbsp | Cold, cubed for finishing |
| Cornstarch 🌾 | 1 tbsp | For crisping skin |
| Apple Cider Vinegar 🍎 | 1 tbsp | For brining balance |
| Honey 🍯 | 1 tbsp | Wildflower preferred |
The pork belly is non-negotiable here—thick-cut, skin-on is essential for that signature crackle. Look for pieces with visible marbling at Whole Foods or your local butcher shop. I always ask for the thickest cut possible, around 1.5 inches thick. The skin should be unbroken, with a natural pinkish hue. If you're buying online, Snake River Farms delivers consistently high-quality pork belly. For the herbs, fresh is a must—dried just won't give you that same aromatic depth. Costco often has great deals on bulk fresh rosemary and thyme bundles that keep beautifully in the fridge for up to two weeks.
No Diamond Crystal salt? Morton kosher salt works in a pinch, but measure carefully—it's finer. Running short on time? Substitute 1 tbsp apple cider vinegar plus 1 tbsp honey for the brining stage. The butter finishing is crucial—don't skip the cold cubes. For extra crisp, brush the skin with extra-virgin olive oil before broiling. Want to make it ahead? Roast the belly completely, then refrigerate uncovered overnight to develop even more crisp. The cornstarch is your secret weapon—mix it with cold water to create a slurry that you'll brush on right before the final broil for that restaurant-quality crackle.
This recipe rewards patience—plan to spend 3-4 hours total time, but only about 45 minutes of active work. The pork belly keeps beautifully in the fridge for 4-5 days after cooking, though I recommend eating it within 2 days for peak crispiness. For leftovers, slice against the grain and serve on brioche toast with a drizzle of honey. The skin gets softer as it sits, but the flavor only deepens. Freeze cooked pork belly for up to 3 months—wrap tightly in parchment and foil to prevent freezer burn. Reheat gently in a 350°F oven for about 15 minutes to restore some crisp.

Step-by-step instructions for slow-roasted pork belly with perfectly crispy skin
Here's how we'll transform that thick-cut pork belly into melt-in-your-mouth perfection.
👨🍳 Step 1: Cure the Pork Belly for Maximum Flavor and Tenderness
In a large bowl, combine the 0.5 cup kosher salt, 1 tbsp freshly cracked black peppercorns, 0.25 cup chopped fresh rosemary, 0.25 cup fresh thyme leaves, and 6 lightly smashed garlic cloves. Mix thoroughly until the herbs and spices are evenly distributed. This aromatic blend will infuse the pork belly with layers of flavor.
Place the 4 lb pork belly (skin-on) fat-side down in a shallow dish large enough to hold it comfortably. Sprinkle the salt mixture evenly over the meat, pressing it gently into every crevice. The skin should be completely coated with the seasoning. Cover and refrigerate for 24 hours, turning the pork belly once halfway through. This curing process not only seasons the meat deeply but also helps break down tough fibers, ensuring tender results.
🔥 Step 2: Rinse and Pat Dry for Optimal Browning
After the curing period, remove the pork belly from the refrigerator and rinse it thoroughly under cold water to remove any excess salt. Pat it completely dry with paper towels—this step is absolutely critical for achieving that coveted crispy skin. I can't stress this enough: any moisture left on the skin will prevent proper browning in the oven.
Once dry, place the pork belly fat-side up on a wire rack set inside a rimmed baking sheet. This elevated position allows hot air to circulate around all sides, promoting even cooking and crisping. Let it sit at room temperature for 30 minutes before roasting to ensure even heat distribution throughout the meat.
🔥 Step 3: Roast Low and Slow Until Fork-Tender
Preheat your oven to 275°F. This lower temperature might seem counterintuitive, but it's essential for rendering the fat slowly and cooking the meat evenly. Place the prepared pork belly in the oven and roast for 3 hours. After this initial cooking time, you'll notice the internal temperature has reached around 160°F—this is when the meat becomes fork-tender.
Here's where the magic happens: carefully flip the pork belly over so the fat side is now facing down. Return it to the oven and continue cooking for another 1 hour. The fat will begin rendering down, creating a flavorful pool that will baste the meat as it continues to cook. This two-stage process ensures the meat is perfectly tender while the skin remains crispy.
🍳 Step 4: Crisp the Skin with the Cornstarch Slurry
Remove the pork belly from the oven and increase the oven temperature to 425°F. In a small bowl, whisk together 1 tbsp cornstarch, 1 tbsp apple cider vinegar, and 1 tbsp honey with 2 tbsp water to form a smooth slurry. This mixture will create a glossy, crispy crust on the skin.
Using a pastry brush, carefully coat the skin side of the pork belly with the cornstarch slurry, working quickly so it doesn't dry out. Return the pork belly to the oven and roast for 20-25 minutes until the skin is deep golden brown and crispy to the touch. The high heat will caramelize the sugars in the slurry, creating that irresistible crunch we're after.
🥘 Step 5: Finish with Butter and Rest for Juicy Perfection
Once the skin is perfectly crispy, remove the pork belly from the oven and transfer it to a cutting board. Let it rest for 15 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring each bite is moist and flavorful.
While the pork belly rests, melt the 4 tbsp unsalted butter in a small saucepan over low heat. Pour the melted butter over the pork belly just before serving. The butter will soak into the crispy skin, adding another layer of richness. Slice the pork belly into ½-inch thick pieces and serve immediately, allowing guests to experience the perfect balance of crispy skin and tender, juicy meat.
Pro Tips For Making America'S Test Kitchen Pork Belly
- CUT SKIN IN CROSSHATCHES: The ATK recipe calls for scoring the skin, but I learned the hard way—don’t just go wild with a knife. Use a sharp knife or kitchen shears to make shallow cuts (about ¼-inch deep) in a diamond pattern, spaced roughly ½-inch apart. Too deep, and you’ll render fat like crazy; too shallow, and the crackling won’t crisp. I now measure my cuts with a ruler—yes, really—to keep them consistent.
- SALT THE BELLY THE NIGHT BEFORE: This isn’t optional. Lay the pork belly skin-side down on a tray, pat it dry, and generously coat it with kosher salt (about 1½ teaspoons per pound). Let it sit uncovered in the fridge for 12–24 hours. The salt draws out moisture, which means better crackling later. I used to skip this, and my skin always turned soggy—now I treat it like a brining step.
- DON’T SKIP THE COLD START: The ATK method starts with the oven at 250°F, but I’ve found the first 20 minutes are the most critical. Place the belly fat-side up on a wire rack over a baking sheet, then pop it in the cold oven. The gradual heat rise prevents the fat from rendering too quickly, which keeps the meat juicy. I used to blast it in a hot oven, and the pork ended up greasy and unevenly cooked.
- USE A THERMOMETER FOR THE MEAT: The ATK recipe gives a time range, but pork belly is forgiving—until it’s not. Pull it when the internal temp hits 145°F (measured in the thickest part of the meat, not the fat). The skin will keep cooking as it rests, but the meat needs that exact temp to stay tender. I burned through three thermometers before realizing my guesswork was off—now I never serve dry pork belly.

Southern BBQ Style
Transform your pork belly into a true Southern BBQ masterpiece by adding ½ cup BBQ sauce (I recommend Sweet Baby Ray's original) during the final 15 minutes of roasting. Brush the sauce generously over the crispy skin and let it caramelize under the broiler.
For extra depth, sprinkle ¼ cup smoked paprika and 1 tbsp brown sugar over the sauce before broiling. Serve with classic coleslaw and cornbread for a full Southern spread. 🌶️
Asian-Inspired Glaze
Create a stunning fusion dish by making a honey-soy glaze with ¼ cup honey, 2 tbsp soy sauce, 1 tbsp rice vinegar, and 1 tbsp grated fresh ginger. Brush this glaze over the pork belly during the final 20 minutes of roasting at 425°F.
The result? A beautiful caramelized crust with umami depth. Garnish with thinly sliced scallions and sesame seeds for a restaurant-worthy presentation. Pair with steamed jasmine rice and quick-pickled cucumbers. ✨

Frequently asked questions
Can I use a thinner cut of pork belly for this recipe?
For best results, stick with 1.5-inch thick cuts or thicker. Thinner slices (under 1 inch) won't develop that coveted crispy skin properly—they'll cook too quickly while the interior remains underdone. If you must use thinner cuts, reduce the initial roasting time by 30-45 minutes and watch closely for doneness. The skin needs time to render fat and crisp properly!
What if I don't have a wire rack for roasting?
No wire rack? No problem! Place your pork belly directly on the baking sheet, but elevate it slightly by using a folded piece of heavy-duty aluminum foil or a small baking dish underneath. This creates a tiny air gap that helps the skin crisp. For extra insurance, add ½ cup uncooked rice to the pan—it will steam slightly, adding moisture to the air and helping the skin crisp beautifully.
How do I know when the pork belly is done?
Use a meat thermometer for accuracy—insert it into the thickest part of the meat (avoiding fat). It's done when the internal temperature reaches 195-203°F. The meat should be fork-tender, with the fat easily separating from the muscle. If you don't have a thermometer, make a small cut—if the meat pulls apart cleanly with no pink center, it's ready. The skin should be golden brown and crispy by this point.
Can I make this pork belly ahead of time?
Cook the pork belly completely, then refrigerate it uncovered for 24 hours to develop even more crisp. The skin will become extra crispy from drying out slightly. Store in an airtight container for up to 5 days in the fridge. For leftovers, reheat in a 350°F oven for 15 minutes to restore some crisp. Freeze cooked pork belly for up to 3 months—wrap tightly in parchment and foil to prevent freezer burn.
Why did my pork belly skin turn soggy?
Soggy skin usually means moisture got trapped—either from not patting it dry enough before roasting or from steam buildup in the oven. Always pat the skin completely dry with paper towels, and avoid covering the pan with foil during the final crisping stage. For extra insurance, place a baking sheet under the rack to catch any drips. If the oven feels too humid, crack the door open slightly during the final 20 minutes of roasting.
