This America's Test Kitchen pork belly recipe delivers the perfect balance of crispy crackling and silky pink meat—a technique I've refined over years of working with heritage pork. The secret lies in precise temperature control and a two-stage cooking process that transforms tough belly into melt-in-your-mouth perfection.
As someone who's cooked thousands of pounds of pork weekly, I can tell you this method works every time.
What sets this recipe apart is the attention to detail that separates home cooks from professionals. We start with a cold start to render fat slowly, then finish with high heat to create that coveted crackling.
The key is patience—rushing this process will leave you with either greasy meat or dry, brittle skin. Trust me, the wait is worth it for that satisfying crunch and tender interior.
By the time you're done, you'll have pork belly with golden, shatteringly crisp skin that snaps when you cut into it, revealing pink meat so tender it nearly dissolves.
This isn't just another pork recipe—it's a showstopper that will impress even the most discerning guests. The technique is foolproof once you understand the science behind it.
Pair this with simple sides like roasted root vegetables or a crisp green salad to let the pork belly take center stage. The fat alone will have everyone reaching for seconds. Here's how to achieve restaurant-quality results at home, step by step.
Ingredients for america's test kitchen pork belly
The secret to perfect pork belly lies in these carefully chosen ingredients and precise technique.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly (skin-on) 🐖 | 2 lb | Heritage breed preferred, 1-inch thick |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred, coarse grain |
| Black Peppercorns 🌶️ | 1 tsp | Freshly cracked, coarse grind |
| Fresh Rosemary 🌿 | ¼ cup | Needles finely chopped, organic preferred |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems removed |
| Garlic Cloves 🧄 | 4 cloves | Smashed but not minced |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin, fruity variety |
| Cornstarch 🌾 | 2 tbsp | For crisping slurry |
| Cold Water 💧 | ½ cup | For slurry mixture |
| Baking Sheet 🍳 | 1 whole | Heavy-gauge aluminum |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty, for tenting |
| Meat Thermometer 🌡️ | 1 whole | Instant-read preferred |
The pork belly is non-negotiable here—heritage breed delivers the best marbling for that melt-in-your-mouth texture. Look for cuts with a thick, unbroken skin (about 1-inch thick) at Whole Foods or specialty butchers. If your grocery store doesn't carry it, check the freezer section—many places stock it pre-portioned. The skin should be pale pink with visible fat cap. For this recipe, you want the belly to be roughly 1-inch thick all over, so if yours is uneven, trim it down before cooking. I always buy extra and freeze portions because good pork belly is worth the investment. Smithfield or Niman Ranch are reliable brands if you're shopping online.
No heritage pork? Regular pork belly still works, but expect slightly less marbling. The herbs can be swapped—fresh sage at half the amount adds depth, or dried thyme at one-third the quantity. For the cornstarch slurry, if you're out, arrowroot powder works 1:1. The key is getting that slurry ratio right: equal parts cornstarch and cold water. Whisk it vigorously to avoid lumps—this creates the crispy lattice on the skin. And trust me on the cold start: room-temperature pork belly will render fat too quickly, leading to greasy skin. The thermometer is your best friend here—145°F internal temp for perfect doneness.
Pork belly keeps beautifully in the fridge for 3-4 days if properly wrapped in parchment and foil. For longer storage, vacuum-seal and freeze for up to 6 months. The crispy skin loses its snap after 2 days, so reheat portions in a 350°F oven for 10-15 minutes to restore the crunch. I always make a double batch—one for the table, one for leftovers. Store cooked portions in an airtight container with a paper towel pressed on top to absorb excess fat. The fat alone makes great cooking oil for future dishes, so save it in a jar in the fridge.

Step-by-step instructions for crispy pork belly with perfect crackling
Let's transform that fatty pork belly into restaurant-quality crisp with silky pink meat underneath.
Prepare the Pork Belly for Maximum Crisp
First, score the skin in a diamond pattern using a sharp knife - make cuts about ½-inch apart and ¼-inch deep. This creates channels where the fat can render out and the skin can crisp evenly. Pat the belly completely dry with paper towels, especially between the fat layers - any moisture will prevent crispy crackling.
In a small bowl, combine the 1.5 tbsp kosher salt, 1 tsp freshly cracked black peppercorns, ¼ cup finely chopped fresh rosemary, and ¼ cup fresh thyme leaves. Rub this mixture all over the belly, pressing it into the skin and fat. The salt will draw out moisture while the herbs add aromatic depth. Let it sit at room temperature for 30 minutes while you preheat your oven to 275°F.
Render the Fat and Develop the Crisp
Place the seasoned pork belly skin-side down on the prepared baking sheet. Slide it into the preheated oven and roast for 2 hours. This low temperature allows the fat to render slowly and evenly without cooking the meat too quickly. After 1 hour, flip the belly skin-side up and continue roasting. You'll see the skin start to turn opaque and the fat begin to pool in the pan.
Here's where the magic happens: when the internal temperature reaches 160°F (about 1 hour 45 minutes in), remove the belly and carefully pour off all but 2 tablespoons of the rendered fat from the pan. This remaining fat will create the crispy crust. Return the belly to the oven, skin-side down, and roast for another 15 minutes until the skin is golden and crispy in spots.
Create the Crisping Slurry
While the belly finishes, whisk together the 2 tbsp cornstarch and ½ cup cold water in a small bowl until completely dissolved. This slurry will create a steam bath that helps develop the crackling. In a separate small bowl, combine the 2 tbsp extra-virgin olive oil with the 4 smashed garlic cloves.
Remove the pork belly from the oven and carefully brush the skin with the garlic oil mixture. This adds flavor while helping to crisp the skin further. Then, pour the cornstarch slurry evenly over the skin, making sure it soaks into the scored channels. The skin should look glossy and wet - this is crucial for the next step.
Develop the Perfect Crackling
Return the belly to the oven and roast at 425°F for 30-40 minutes, flipping once halfway through. The high heat will cause the moisture in the slurry to evaporate rapidly, creating steam that puffs up the skin and creates those coveted cracklings. You'll hear popping sounds as the skin expands - this is normal and exactly what we want.
Watch carefully for the skin to turn a deep golden brown with crispy, crackling sections. The internal temperature should reach 195-203°F - this is the perfect range for tender meat. Remove from the oven when you see the crackling forming and the skin is crispy to the touch. Let it rest for 15 minutes before slicing to allow the juices to redistribute.
Slice and Serve with Confidence
Using a sharp knife, slice the pork belly against the grain into ¼-inch thick slices. The meat should be silky pink and pull apart easily, while the skin should be crispy enough to stand up on its own. Serve immediately with the rendered fat drizzled over the top - this adds incredible flavor and moisture.
For the best experience, serve with simple sides like roasted potatoes or a crisp green salad. The contrast between the crispy skin and tender meat makes every bite a revelation. Don't be tempted to skip the resting time - this is what makes the difference between good pork belly and exceptional pork belly.
Pro Tips For Making America'S Test Kitchen Pork Belly
- CRACK THE SKIN FIRST: Use kitchen shears to snip the skin in a crosshatch pattern—about 1/4-inch apart—before salting. This lets the fat render properly and gives you that coveted crisp without fighting stubborn skin later. (Yes, even if it looks like you’re defacing the pork.)
- SALT LIKE IT’S 1950: The ATK recipe calls for a lot of salt—don’t skimp. Use 1 tablespoon per pound of pork belly, and rub it in generously on both sides of the skin. I learned this the hard way: under-salted pork belly tastes bland no matter how long you cook it.
- DON’T RUSH THE REST: After roasting, tent the pork with foil and let it rest for at least 20 minutes before slicing. Cutting too soon sends all that rendered fat pooling out instead of staying where it belongs—crispy skin and juicy meat.
- LOW AND SLOW AFTER THE CRISP: Once the skin is golden and blistering, drop the oven to 325°F and finish cooking. This keeps the fat from turning greasy while the meat stays tender. (I used to blast it at 400°F the whole time—big mistake.)

Frequently asked questions
Why does the America's Test Kitchen recipe use a cold start for pork belly?
A cold start prevents the fat from rendering too quickly, which would make the skin greasy instead of crispy. The 275°F low temperature allows the fat to melt gradually while the meat cooks evenly. This two-stage process creates that perfect contrast between crispy skin and tender meat.
Can I substitute regular pork belly for heritage breed?
Yes, but you may need 10-15 extra minutes in the oven since heritage pork has more marbling. Look for cuts with thick, unbroken skin (about 1-inch thick) and trim uneven areas. The scoring technique works the same—just monitor the internal temperature closely.
What's the best way to reheat leftover pork belly?
For best results, slice the pork belly and reheat in a 350°F oven for 10-15 minutes on a wire rack to restore crispiness. Avoid microwaving—it makes the skin soggy. Store leftovers in an airtight container with a paper towel to absorb excess fat.
Why did my pork belly skin turn out greasy instead of crispy?
This usually happens when the fat renders too quickly (room-temperature pork) or the skin wasn't dry enough before cooking. Always pat the belly completely dry and use the cold start method. If it happens, try the cornstarch slurry trick during the final crisping stage.
How do I know when the pork belly is perfectly cooked?
The ideal internal temperature is 195-203°F—this gives you that signature crackling skin with tender meat. The skin should be deep golden brown and crispy to the touch. If you see pink smoke, it's ready! Always let it rest for 15 minutes** before slicing.
