This Japanese thin-sliced pork belly recipe delivers the perfect balance of crispy skin and silky centers that make every bite unforgettable. After years of perfecting pork techniques—from my CIA training to running a 2,000-pound weekly pork operation—I’ve simplified the art of transforming fatty pork belly into restaurant-quality slices at home.
The secret lies in precise slicing, gentle boiling, and quick searing—techniques that preserve texture while building deep umami flavor.
The process begins with thinly slicing the pork belly against the grain to ensure tender bites, then gently boiling to render fat without overcooking.
What sets this apart is the optional tare sauce—a sweet-savory glaze made from soy, mirin, and sugar—that elevates simple slices into a dish worthy of izakaya counters.
Even without the sauce, the pork’s natural richness shines through, making it versatile enough for stir-fries, ramen toppings, or serving with steamed rice and pickled vegetables.
By the time you’re done, you’ll have crispy-edged, melt-in-your-mouth pork slices that crackle with every bite—just like the ones I’ve served at my restaurant. The fat renders perfectly, leaving you with tender meat that’s rich but never greasy.
This isn’t just a recipe; it’s a technique that transforms a humble cut into something extraordinary, all while keeping the process manageable for home cooks.
Pair it with a simple miso broth for shabu-shabu style, or serve it as-is with steamed rice and quick-pickled daikon for a complete Japanese-inspired meal. The best part? You’ll have the confidence to slice and cook pork belly like a pro, even if you’ve never attempted it before.
Let’s get started on creating this restaurant-quality dish at home.
Ingredients for japanese thin sliced pork belly
Four ingredients transform pork belly into crispy-skin, silky-center perfection—plus a few extras for serving.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🥓 | 2 lb | Skin-on, fatty cut preferred |
| Water 💧 | 4 cups | For gentle boiling |
| Kosher Salt 🧂 | 1 tbsp | For boiling water |
| Neutral Oil 🫒 | ½ cup | Vegetable or canola oil |
| Soy Sauce 🍶 | ¼ cup | Japanese or tamari preferred |
| Mirin 🍶 | ¼ cup | Sweet cooking wine |
| Granulated Sugar 🍚 | 2 tbsp | For tare sauce |
| Garlic Cloves 🧄 | 4 cloves | Minced for tare sauce |
| Fresh Ginger 🌿 | 1 tbsp | Finely grated |
| Steamed White Rice 🍚 | 2 cups | For serving |
| Pickled Daikon Radish 🥕 | 1 cup | Store-bought or homemade |
| Sesame Seeds 🌰 | 1 tbsp | Toasted for garnish |
The pork belly is everything here. Look for a thick, fatty cut with a thick layer of fat—Costco or specialty butchers often carry the best. If you can't find a whole piece, two 1-pound slabs work. The fat renders beautifully during boiling, but don't skip the skin—it's what gives you that coveted crisp. For the tare sauce, Japanese soy sauce and mirin are non-negotiable for authentic flavor. I grab mine at H Mart or Japanese grocery stores, but any Asian market will have them. If you're using regular soy sauce, add an extra 1/2 teaspoon of sugar to balance the flavor.
No mirin? Dry sherry plus 1 teaspoon sugar works in a pinch. Short on time? Skip the tare sauce entirely—the pork's natural richness still shines. For the oil, vegetable or canola are neutral enough not to overpower, but avocado oil adds a nice buttery note if you're feeling fancy. The garlic and ginger can be swapped for 2 teaspoons garlic powder and 1 teaspoon ground ginger if fresh isn't available. And if you're feeling adventurous, add a pinch of white pepper to the boiling water for a subtle restaurant touch.
Boiled pork belly keeps 3 days in the fridge, sealed tightly in its cooking liquid. For best results, reheat in a skillet with a splash of water over medium heat until crispy again. The tare sauce? It lasts 1 week in the fridge, but I usually make just enough for one batch since it's so quick to whip up. Store the rice and pickled daikon separately—they'll stay fresh longer. And pro tip: save the pork fat! It's liquid gold for future stir-fries or roasting vegetables. Just strain it through a fine-mesh sieve after boiling.

Step-by-step instructions for Japanese thin-sliced pork belly
Here's how to achieve that perfect balance of crispy skin and tender meat every time.
Prepare and Boil the Pork Belly
Start by scoring the skin of the 2 lb pork belly in a diamond pattern using a sharp knife. This creates channels for the fat to render out while keeping the skin intact. Place the pork belly skin-side down in a large pot and add the 4 cups water. Bring to a boil over medium-high heat.
Once boiling, reduce heat to low and simmer for 1 hour, maintaining a gentle simmer. You'll see fat bubbles rise to the surface—this is normal. The pork belly is cooked when it reaches an internal temperature of 160°F and the skin begins to pull away from the fat in some areas. Be careful not to let it boil vigorously, as this can make the meat tough.
Create the Tare Sauce
While the pork belly cooks, prepare the tare sauce by combining the 0.25 cup soy sauce, 0.25 cup mirin, 2 tbsp granulated sugar, 4 minced garlic cloves, and 1 tbsp finely grated fresh ginger in a small saucepan. Bring to a boil over medium heat, then reduce heat to low and simmer for 5-7 minutes until the mixture thickens slightly and reduces by about half.
Strain the sauce through a fine-mesh sieve to remove the ginger and garlic, then set aside. This sauce will add deep umami flavor and balance the richness of the pork belly. The reduction process concentrates the flavors, making every bite more impactful. Taste and adjust seasoning if needed—you want it to be sweet, salty, and slightly tangy.
Slice and Marinate the Pork Belly
Remove the pork belly from the pot and let it cool for 15 minutes before handling. The fat should be firm enough to slice cleanly. Working against the grain, slice the pork belly into ⅛-inch thick pieces. Place the slices in a shallow dish and pour the prepared tare sauce over them. Let them marinate for at least 30 minutes at room temperature.
This marination step is crucial for infusing flavor and ensuring the slices stay tender. The acidity in the mirin and soy sauce helps tenderize the meat while the sugar caramelizes slightly, adding depth. Don't skip this step—it's what transforms good pork belly into exceptional pork belly.
Pan-Fry for Crispy Perfection
Heat the 0.5 cup neutral oil in a large skillet over medium-high heat until it shimmers but doesn't smoke. Working in batches to avoid crowding, add the marinated pork belly slices and cook for 1-2 minutes per side until the edges are deep golden brown and the skin is crispy.
You'll know they're ready when the pork releases easily from the pan and the skin has that satisfying crunch. The internal temperature should reach 145°F. Transfer the cooked pork to a paper towel-lined plate to drain excess oil. The high heat ensures a crispy exterior while keeping the interior silky and juicy—this is the magic of proper technique.
Serve with Traditional Sides
Arrange the crispy pork belly slices on a platter with the 2 cups steamed white rice and 1 cup pickled daikon radish. Sprinkle with the 1 tbsp toasted sesame seeds just before serving. The contrast of textures—crispy pork, soft rice, and crunchy radish—makes every bite exciting.
Serve immediately while the pork is still crispy. The sesame seeds add a nutty aroma that complements the rich pork and tangy radish beautifully. This dish is all about balance—crispy skin, tender meat, and refreshing sides that cut through the richness. Enjoy it while warm for the best experience!
Pro Tips For Making Japanese Thin Sliced Pork Belly
- Slice Against the Grain: Thin slices tear when you pull them in the wrong direction—look for the muscle fibers and cut perpendicular. I used to waste half my pork belly on this, but now I just check the grain first and slice like I’m cutting paper.
- Salt Before Searing: Toss the pork belly in kosher salt at least 30 minutes before cooking—it seasons deeper and helps render fat faster. I learned this the hard way when my first batch tasted bland no matter how much soy sauce I added.
- High Heat, Then Walk Away: Get the pan screaming hot, add the pork belly, and let it sear undisturbed for 2 full minutes. Crowding the pan steams the meat instead of crisping it—your future self will thank you for the patience.
- Deglaze with Soy Sauce: After searing, splash in just enough soy sauce to coat the pan—about 1 tablespoon per pound of pork. Scrape up those browned bits; they’re packed with flavor and make the sauce richer than plain soy alone.

Frequently asked questions
Why is it important to slice the pork belly against the grain?
Slicing against the grain breaks up the muscle fibers, creating shorter strands that cook more evenly and result in a tender bite. The grain runs horizontally across the pork belly—look for the direction of the muscle fibers before slicing. If you cut with the grain, the meat will be tough and chewy, even after boiling.
Can I substitute mirin in the tare sauce?
Yes, but the flavor will differ slightly. Replace mirin with a mix of dry sherry and 1 teaspoon sugar per ¼ cup mirin. For a non-alcoholic option, use rice vinegar plus 1 extra teaspoon sugar. The sauce will be slightly less sweet, but it’ll still add depth to the pork. The key is balancing sweetness and acidity.
How do I know when the pork belly is fully cooked?
The pork belly is done when it reaches an internal temperature of 160°F and the skin begins to pull away from the fat in some areas. You’ll also see the meat turn opaque and firm to the touch. If you’re unsure, use a meat thermometer—overcooking will make the meat dry, while undercooking leaves it too fatty.
What’s the best way to reheat leftover pork belly slices?
Reheat in a skillet over medium heat with a splash of water or oil to restore crispiness. Work in batches to avoid steaming. For microwave reheating, cover with a damp paper towel and heat for 10-15 seconds—but expect less crispiness. The goal is to warm through while keeping the texture intact.
Can I use this recipe with pork shoulder instead of pork belly?
Pork shoulder won’t work the same way—it’s leaner and lacks the fat marbling that makes pork belly ideal. The fat renders beautifully during boiling, creating that signature crispy skin. If you must use shoulder, trim excess fat and adjust boiling time to 45 minutes, but the texture and flavor won’t be identical.
