Ingredients for america's test kitchen crispy pork belly
The secret to shatterproof pork belly lies in these 11 simple ingredients—no shortcuts, just restaurant-quality results.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🐖 | 2 lb | Skin-on, thick-cut preferred |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 tsp | Freshly cracked preferred |
| Fresh Rosemary 🌿 | ½ cup | Chopped, stems removed |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For scoring and finishing |
| Garlic Cloves 🧄 | 4 cloves | Smashed, for scoring |
| Cornstarch 🌾 | ¼ cup | For crisping (optional) |
| Unsalted Butter 🧈 | ½ cup | Melted, for basting |
| Apple Cider Vinegar 🍎 | 1 tbsp | For scoring |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Granulated Sugar 🍚 | 1 tbsp | For caramelization |
The pork belly is the star—look for thick-cut pieces with a good layer of fat. Costco or specialty butchers have the best cuts, but most grocery stores carry it too. If your piece is uneven, trim it to about 1-inch thickness for even cooking. Fresh herbs matter here: Trader Joe's sells pre-chopped rosemary and thyme, but I always grab whole sprigs and chop them myself. The cornstarch is optional but worth it for extra crispiness—just toss the scored belly in it before roasting.
No fresh rosemary? Dried works at half the amount, but fresh is ideal. Short on garlic? Garlic powder at 1/4 tsp per clove gets you close, but nothing beats the real thing. The apple cider vinegar can be swapped for lemon juice if that's what you've got. For the scoring, use a sharp knife—no serrated blades here. The scoring creates channels for fat to escape, which is key to that crispy exterior. If you're feeling fancy, add a pinch of smoked paprika to the cornstarch for extra depth.
Pork belly keeps best in the fridge for 3-4 days if you have leftovers—wrap it tightly in foil to retain moisture. For longer storage, freeze it for up to 3 months. The crispy skin is best eaten fresh, but the meat stays tender for reheating. I like to portion mine into single-serving containers so I can grab a piece straight from the freezer and roast it later. The aroma alone will have your whole house smelling like a Southern cookout—worth every minute of effort.

Step-by-step instructions for america's test kitchen crispy pork belly
Here's how to achieve that legendary shatterproof crackling with melt-in-your-mouth pork.
👨🍳 Step 1: Score and Cure the Pork Belly
Lay the 2 lb pork belly skin-side up on a cutting board. Using a sharp knife, score the skin in a diamond pattern, cutting about ½-inch deep without piercing the fat underneath. This creates crispy crackling while keeping the meat tender. Spread the 2 tbsp kosher salt evenly over the meat and fat sides, then press it in firmly.
Place the scored belly on a wire rack set over a baking sheet. Refrigerate uncovered for 12-24 hours. This curing process draws out moisture, which is crucial for crispy crackling. You'll know it's ready when the surface feels dry to the touch and the skin looks slightly translucent.
🔥 Step 2: Preheat and Render the Fat
Preheat your oven to 250°F. Transfer the cured belly to a baking dish and roast for 2 hours until the internal temperature reaches 160°F. The skin should be pale and the fat should render out, leaving you with about ½ cup of golden liquid in the pan. This slow cook prevents the skin from crisping too soon.
Here's the thing—don't touch it during this process. Every time you open the oven, you risk steaming the skin instead of rendering the fat. The rendered fat is what creates that irresistible crackling, so let it work its magic undisturbed.
🍳 Step 3: Create the Crispy Coating
In a bowl, mix together the 0.25 cup cornstarch, 0.25 cup chopped fresh thyme, 0.5 cup chopped fresh rosemary, 1 tbsp granulated sugar, and 1 tsp freshly cracked black peppercorns. This dry rub will give you that perfect balance of crispy and flavorful. Brush the belly with 2 tbsp extra-virgin olive oil to help the coating stick.
Pat the mixture all over the belly, pressing it into the skin and fat. The cornstarch is optional but makes a HUGE difference—it creates that shatterproof texture we're after. Return the belly to the oven and roast for another 30 minutes at 250°F. This second cook helps the coating adhere properly.
🔥 Step 4: Crisp at High Heat
Increase the oven temperature to 425°F. Transfer the belly to a baking sheet and roast for 25-30 minutes until the skin is deep golden brown and crispy enough to shatter. You'll see the skin puff up slightly and develop those beautiful crackling layers. The internal temperature should reach 195-205°F—this is when the collagen fully breaks down for that silky texture.
Don't walk away during this final stage. Check it at the 20-minute mark—your oven might run hot, so start testing early. If it browns too quickly, tent it loosely with foil. The goal is that perfect balance of crispy skin and tender meat.
⏰ Step 5: Rest and Serve
Remove the belly from the oven and transfer it to a cutting board. Let it rest for 10-15 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat. While it rests, melt the 0.5 cup unsalted butter with 1 tbsp apple cider vinegar in a small saucepan over low heat.
Slice the belly into ¼-inch thick pieces against the grain. The crackling should shatter at the touch, revealing that beautiful pink meat underneath. Drizzle with the melted butter mixture before serving. Each bite should deliver that perfect combination of crispy, crackly skin and melt-in-your-mouth pork—worth every minute of the process!
Pro Tips For Making America'S Test Kitchen Crispy Pork Belly
- CRACK THE SKIN FIRST: I learned this the hard way—skipping the skin-cracking step means uneven cooking and a soggy final product. Use kitchen shears to slice the skin in a crosshatch pattern (about 1/4-inch apart) before salting. This lets the fat render properly and gives you that coveted crispy exterior.
- SALT LIKE IT’S 1950: The ATK recipe isn’t kidding when it says "generously." Use about 1.5 teaspoons of kosher salt per pound of pork belly, and don’t rub it in—just press it into the meat. After 40 minutes, flip and repeat. (Yes, even if you’re impatient like me.)
- DON’T RUSH THE REST: After roasting, the pork belly needs a solid 5-10 minutes under foil to let the internal temp drop to 145°F. I used to skip this, and the slices would always end up chewy. Trust the process—your future self will thank you.
- USE A THERMOMETER: Guessing the doneness of pork belly is how you end up with either raw fat or burnt skin. Aim for 160°F internal temp (measured in the thickest part), then let it rest. No thermometer? At least wait until the skin is deep golden and the fat is opaque—close, but not perfect.
Common mistakes when making perfect results
Over-Skipping Rendering
One of the biggest mistakes is rushing the low-and-slow rendering phase. I’ve seen home cooks impatiently crank the oven to 425°F right away, thinking it’ll save time—but that’s how you end up with a greasy, soggy mess instead of crispy crackling.
The 250°F render is non-negotiable for breaking down collagen and rendering fat properly. Trust me, the extra 2 hours at low heat is what gives you that perfect texture. 🌡️
Skipping the Cure
Many people skip the 12-24 hour salt cure, thinking it’s optional. But this step is what dries out the surface just enough for that magical crisp. Without it, your skin will steam instead of crisp, and you’ll end up with a sad, limp result.
I’ve tested both ways—trust me, the cure makes all the difference. Pro tip: Use Diamond Crystal kosher salt—it’s coarser and works better than table salt.
Piercing the Fat Layer
When scoring the skin, it’s tempting to cut too deep and pierce the fat underneath. But that’s how you lose all that precious rendered fat, which is what creates the crackling. Keep your cuts about ½-inch deep—just enough to create channels for fat to escape without breaking through.
I use a sharp Wüsthof chef’s knife** for precision, and I always test the depth with my finger first.
Using Wrong Equipment
Some home cooks try to crisp pork belly in a skillet or air fryer without proper prep. While those methods can work, they’re not ideal for large cuts. Your oven is the best tool for even heat distribution.
If you’re set on a skillet, use a cast iron Dutch oven and render the fat first at 275°F before cranking up the heat. But for best results, stick with the oven method—it’s foolproof.
Overlooking Rest Time
Skipping the 10-15 minute rest after roasting is a cardinal sin. This is when the juices redistribute, ensuring every bite is tender. I’ve seen people slice into pork belly fresh out of the oven, only to be met with dry, stringy meat.
Let it rest on a cutting board—it’s worth the wait. While it rests, melt that ½ cup butter with vinegar for the perfect finishing drizzle.
Ignoring Internal Temp
Guessing when pork belly is done leads to disappointment. You need that 195-205°F internal temp to break down collagen fully. Use a meat thermometer—no excuses. I swear by the ThermoWorks Smoke because it’s precise and durable.
If you pull it out too early, you’ll have tough meat. Too late? You risk burning the skin. Aim for that sweet spot where the skin is deep golden and the meat is silky.

Frequently asked questions
Why does the America's Test Kitchen recipe use a diamond pattern for scoring?
The diamond pattern creates more surface area for fat to render out while maintaining structural integrity. This design allows the skin to crisp evenly and creates those signature crackling layers. The channels also help the cornstarch coating adhere better during the crisping phase.
Can I substitute cornstarch with another crisping agent?
Yes! You can use panko breadcrumbs or crushed potato chips (like potato chips) for a different texture. However, cornstarch gives the most delicate shatterproof crackling. For a gluten-free option, try arrowroot powder at the same ratio. The key is creating a fine, dry coating that sticks to the fat.
How do I know when the pork belly is perfectly crispy?
Look for deep golden brown color with visible crackling layers that puff slightly when sliced. The skin should shatter when touched with tongs, revealing the pink meat underneath. The internal temperature should read 195-205°F—this is when the collagen fully breaks down for that silky texture.
What's the best way to reheat leftover pork belly?
For maximum crispiness, reheat in a 400°F oven for 10-15 minutes on a wire rack. For a quick option, use a skillet over medium heat for 2-3 minutes per side. Avoid microwaving—it makes the skin soggy. The meat stays tender for up to 3 days when stored properly.
Can I make this recipe without a meat thermometer?
You can estimate by visual cues: the skin should be deep golden brown with visible crackling. The meat should pull away from the bone slightly when tested with a fork. However, for perfect results, a thermometer ensures you hit that 195-205°F range where collagen fully breaks down. A budget option is the ThermoWorks Smoke thermometer.
