Ingredients for america's test kitchen crispy pork belly
Pork belly transforms from tough to tender with these precise ingredients and techniques.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🥓 | 3 lb | Skin-on, thick-cut preferred |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | For seasoning |
| Granulated Sugar 🍚 | 1 tbsp | For crisping aid |
| Cornstarch 🌾 | 1 tbsp | For extra crunch |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For coating |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for rendering |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, optional garnish |
| Fresh Rosemary Sprigs 🌿 | 4 whole | For aromatics |
| Garlic Cloves 🧄 | 6 cloves | Smashed, for flavor |
| Apple Cider Vinegar 🍎 | 1 tbsp | For acid balance |
| Water 💧 | ½ cup | For rendering bath |
The pork belly is non-negotiable—look for thick-cut pieces with marbled fat (the more, the better). Whole Foods or specialty butchers carry the best cuts, but any grocery store's pork belly works if it's fresh. The skin should be thin and unbroken—thicker skin means more time crisping. If your cut is large, ask the butcher to trim it to about 3 pounds for perfect portion control. For this recipe, skin-on is essential—it's what creates that legendary crackling crust. If you find belly with the skin already scored, skip that step unless you want extra crispy pockets.
No Diamond Crystal kosher salt? Morton's works too, but measure carefully—it's coarser. Running out of cornstarch? Arrowroot powder at the same amount gives identical crispiness. The olive oil should be extra-virgin—cheap oil won't crisp as well. For the butter, grab the coldest block from your fridge (or freeze it 20 minutes first). The thyme and rosemary can be swapped for sage if that's what you have, but keep the same quantity. Garlic lovers can double it, but traditionalists might prefer just the 6 cloves—trust me, it's plenty. The apple cider vinegar is optional but balances the richness beautifully.
Store any leftover pork belly in an airtight container for up to 5 days—it reheats wonderfully. For longer storage, freeze portions for 3 months. The crisp will soften slightly when reheated, but a 5-minute broil at 450°F restores that satisfying crunch. Pro tip: Save the rendered fat! Strain it through a fine-mesh sieve after cooking and store it in the fridge for frying eggs or roasting vegetables—it's liquid gold. The herbs keep fresh for 1 week in the fridge, wrapped in damp paper towels.

Step-by-step instructions for crispy pork belly with perfect texture
Here's how to achieve that legendary knife-sharp crunch with melt-in-your-mouth interiors every time.
Prepare the Pork Belly for Maximum Crisp
Start by scoring the pork belly skin in a diamond pattern using a sharp chef's knife, cutting about ¼ inch deep without piercing the fat. This creates more surface area for crisping while allowing the fat to render evenly. Pat the skin completely dry with paper towels—this is absolutely critical for achieving that crispy texture. Any moisture left behind will steam the skin instead of crisping it.
In a small bowl, combine the 1.5 tbsp kosher salt, 0.5 tsp freshly ground black pepper, 1 tbsp granulated sugar, and 1 tbsp cornstarch. The sugar and cornstarch work together to promote browning and add extra crunch to the exterior. Rub this mixture all over the pork belly, pressing firmly so it adheres well to both the skin and fat. Let it sit at room temperature for 30 minutes while you prepare the oven.
Render the Fat and Build Flavor Base
Preheat your oven to 250°F—this low temperature is key for slow, even fat rendering. Place a wire rack in a deep baking dish and position the pork belly fat-side up on the rack. Pour the 0.5 cup water into the bottom of the dish. This creates a steam bath that helps render the fat gently without drying out the meat.
Bake for 2 hours, rotating the dish halfway through for even cooking. You'll see the fat slowly liquefy and pool in the dish—this is normal and essential for creating tender meat. The skin should start to turn opaque and slightly golden. Don't be tempted to check on it too often; every time you open the oven, you lose heat and moisture. After 2 hours, remove the pork belly from the oven and let it cool slightly for 10 minutes—this makes it easier to handle.
Create the Crispy Crust with High Heat
While the pork belly is cooling, prepare your broiler. Increase the oven temperature to its highest setting (usually 500°F) and position the rack in the middle position. Line a baking sheet with foil and place a wire rack on top. This setup allows hot air to circulate around the pork belly for even browning.
Carefully transfer the pork belly to the prepared rack, skin-side up. Brush the skin generously with the 2 tbsp extra-virgin olive oil—this helps create a golden, crispy crust. Place the pork belly under the broiler and cook for 8-10 minutes, watching closely. You're aiming for deep golden brown color with some charred spots—this is where that knife-sharp crunch comes from. Rotate the pork belly halfway through for even browning.
Finish with Aromatics and Rest
Remove the pork belly from the broiler and transfer it to a cutting board. In a small skillet over medium heat, melt the 0.5 cup unsalted butter with the 4 whole fresh rosemary sprigs and 6 smashed garlic cloves for 2 minutes until fragrant. Pour this aromatic butter mixture over the hot pork belly, letting it penetrate the skin and fat.
Let the pork belly rest for 15 minutes before slicing—this allows the juices to redistribute and ensures each slice stays moist. While it rests, chop the 0.25 cup fresh thyme leaves and mix them with the 1 tbsp apple cider vinegar to create a quick garnish. Slice the pork belly against the grain into ¼-inch thick slices and serve immediately, garnished with the thyme-vinegar mixture.
Pro Tips For Making America'S Test Kitchen Crispy Pork Belly
- Score the Belly: Use a sharp knife to cut shallow crosshatch marks—about 1/8-inch deep—before seasoning. This isn’t just for looks; it lets the fat render faster and creates more surface area for that perfect crust. (Yes, it’s tedious, but your future self will notice the difference when the pork turns golden instead of greasy.)
- Salt Like It’s 1999: The ATK recipe calls for a lot of salt—don’t skimp. Use 1 tablespoon kosher salt per pound of pork belly, and let it sit uncovered in the fridge for at least 4 hours (overnight is better). I learned this the hard way: rushed salting = bland pork, no matter how crispy the outside gets.
- Don’t Rush the Render: Start the pork belly fat-side down in a cold pan—cold—and turn the heat to medium-low. Let it slowly render its own fat for 10–15 minutes before cranking up the heat to sear. Crowding the pan or rushing this step means you’ll end up with soggy pork instead of crackling crispness.
- Sugar First, Cornstarch Second: When coating the pork in the sugar-cornstarch mix, apply it in two layers: pat on the sugar first, then the cornstarch. The sugar caramelizes first, locking in moisture, while the cornstarch gives you that shatteringly crisp exterior. Skip the order, and you’ll get a sticky mess instead of a golden crust.
Pro cooking tips for this dish
Temperature Precision
This recipe hinges on two critical temperature phases: the 250°F low-and-slow render and the 500°F broil finish. I use a ThermoWorks Smoke thermometer to monitor both the oven and pork belly internal temperature—it’s worth the investment.
The low heat breaks down collagen gently, while the high heat creates that coveted crackling crust. Never skip the 10-minute rest after rendering; it prevents fat splatter when you broil. 🌡️
Scoring Like a Pro
The diamond pattern scoring isn’t just decorative—it’s functional. Cutting ¼-inch deep with a sharp chef’s knife (I swear by my Wüsthof) creates maximum surface area for crisping. Press the knife at a 45-degree angle and work quickly to avoid tearing the skin.
Pro tip: Score while the pork belly is still cold—it’s easier to control. If your knife isn’t sharp, you’ll end up with ragged cuts that crisp unevenly.
Fat Rendering Secrets
That ½ cup water in the baking dish isn’t just for show—it creates a steam bath that renders fat without drying the meat. If your pork belly has thick fat layers, add an extra ¼ cup water.
The fat should pool in the dish like liquid gold; if it’s not rendering, your oven might not be hot enough. I’ve seen home cooks rush this step, but patience here makes all the difference. The skin should turn opaque and slightly golden before moving to the broiler. ⏱️
Broiling Perfection
Position the rack in the middle of the oven for even heat distribution—top racks can create hot spots. Watch the pork belly like a hawk during those 8-10 minutes under the broiler; it moves fast. If you see smoke, lower the heat slightly.
The skin should be deep golden with some charred spots—this is where the magic happens. Rotate the pork belly halfway through for even browning, and never skip the olive oil brush before broiling. It’s the secret to that knife-sharp crunch. 🔥
Aromatic Finishing
The butter, rosemary, and garlic aren’t just garnishes—they infuse the pork belly with layers of flavor. Melt the ½ cup cold butter with aromatics for just 2 minutes—any longer and it’ll burn. Pour it over the hot pork belly immediately; the heat will help the fat penetrate the skin.
Let it sit for 15 minutes before slicing—this resting time ensures every bite is juicy. I like to garnish with thyme and vinegar for a bright contrast to the richness. 🌿
Equipment Must-Haves
You don’t need a fancy setup, but a few key tools make this recipe foolproof. A wire rack (like the Ozeri Touchstone) elevates the pork belly for even cooking, and a sharp chef’s knife is non-negotiable.
For broiling, I use a Vitamix stand mixer attachment as a makeshift rack—it’s sturdy and elevates perfectly. If you’re short on time, a deep baking dish with a rack works just as well. The goal is even heat circulation, not fancy gadgets. 💡

Frequently asked questions
Why does America's Test Kitchen recommend scoring the pork belly skin?
The diamond pattern scoring creates more surface area for crisping while allowing fat to render evenly. This technique prevents thick, unbroken skin from staying tough—it transforms into that coveted knife-sharp crunch. The cuts should be about ¼-inch deep to maximize crispiness without piercing the fat layer.
Can I use a different cut of pork belly if I can't find thick-cut?
Thin-cut pork belly will crisp faster but may not render as much fat. For best results, ask your butcher to trim it to about 3 pounds with even thickness. If all you have is thin-cut, reduce the broiling time to 6-8 minutes to avoid burning. The sugar-cornstarch rub still works wonders for extra crunch!
What's the secret to getting that perfect crispy skin every time?
Three things: completely dry skin (pat with paper towels), olive oil brush before broiling, and high heat (500°F broiler). The sugar and cornstarch in the rub also promote browning. Never skip the 10-minute rest after rendering—it prevents fat splatter that can ruin crispiness.
How do I know when the pork belly is fully rendered?
The fat should have liquefied and pooled in the baking dish like golden liquid. The skin will turn opaque and slightly golden, and the internal temperature should reach 160°F when measured in the thickest part. If the fat isn't rendering, check your oven temperature—it might need calibration.
Can I make this recipe in an air fryer instead of the oven?
While possible, an air fryer won't render fat as effectively. For best results, use the oven for the 250°F render phase (2 hours), then transfer to a broiler or air fryer at 400°F for 8-10 minutes for crisping. The air fryer can create crispiness, but the low-and-slow rendering is essential for tender meat.
