Pork belly intimidated me for years. I thought it was a restaurant thing. Turns out, if you cook pork belly in a slow cooker, the low and slow heat does literally all the heavy lifting for you. The fat renders down, the meat gets fall-apart tender, and that soy-ginger glaze clings to every single layer like it was born to be there.

What makes this version different is the quick sear before it goes in the slow cooker. Five extra minutes, big payoff. You get that deep caramelized crust that stands up even after hours of braising.

My teenager declared this her “favorite dinner ever” and my toddler ate more than he does at Thanksgiving. That’s the real endorsement right there.

Ingredients to Cook Pork Belly in Slow Cooker

For the pork belly

• 2.5 lbs pork belly, skin-on, ask your butcher to score the skin for you, or do it yourself with a sharp knife
• 1 tablespoon neutral oil (avocado or vegetable)
• 1 teaspoon kosher salt
• 1 teaspoon black pepper
• 1 teaspoon Chinese five spice, this is the secret layer of flavor; don’t skip it

For the slow cooker braising sauce:

• ¼ cup low-sodium soy sauce, low-sodium keeps it from getting too salty as it reduces
• 3 tablespoons honey
• 2 tablespoons brown sugar, packed
• 2 tablespoons rice vinegar
• 1 tablespoon sesame oil
• 5 garlic cloves, minced
• 1 tablespoon fresh ginger, grated, fresh is non-negotiable here; powdered ginger tastes completely different
• ½ teaspoon red pepper flakes, optional but I always add them
• ¼ cup chicken broth

For garnish

• 3 green onions, thinly sliced
• 1 tablespoon sesame seeds

How to Cook Pork Belly in a Slow Cooker — Step by Step

Step 1: Score and season the pork belly

Pat the pork belly completely dry with paper towels, this is important because moisture is the enemy of a good sear. Using a sharp knife, score the skin in a crosshatch pattern, cutting about ¼ inch deep. Don’t cut all the way through the fat layer. Then rub the entire piece with salt, pepper, and Chinese five spice on all sides. The dry surface and spice rub set you up for a gorgeous crust in the next step.

Step 2: Sear the pork belly

Heat your oil in a cast iron skillet or heavy pan over medium-high heat until shimmering. Place the pork belly skin-side down first and sear for 3 to 4 minutes without moving it, let it do its thing. Then flip and sear the meaty side for another 2 to 3 minutes. You want deep golden-brown color on both sides. This step builds flavor that low and slow cooking alone cannot replicate. The Maillard reaction creates caramelized, complex notes that make the final dish taste like you actually tried.

Step 3: Mix your braising sauce

While the pork rests off the heat, whisk together all the sauce ingredients in a bowl, soy sauce, honey, brown sugar, rice vinegar, sesame oil, garlic, ginger, red pepper flakes, and chicken broth. Give it a taste. It should be bold, slightly sweet, a little tangy, with a good garlicky punch. This is the liquid the pork belly will braise in for hours, so make sure it tastes good to you now.

Step 4: Load the slow cooker

Place the seared pork belly into your slow cooker insert, meaty side down. Pour the braising sauce over and around it evenly. You want the sauce to come about halfway up the sides of the pork, the top portion will steam and braise from the trapped heat, and the fat layer on top will baste itself as it renders.

Step 5: Cook low and slow

Cover and cook on LOW for 6 to 7 hours or HIGH for 3.5 to 4 hours. I almost always go low and slow, the difference in texture is noticeable. At the low setting, the fat has more time to render gradually into the meat without the muscle fibers tightening up. When it’s done, the pork belly should be completely fork-tender and the sauce will have deepened in color and thickened slightly.

Step 6: Glaze and broil for the finish

This is the step that takes it from great to absolutely ridiculous. Carefully transfer the pork belly to a foil-lined baking sheet. Spoon or brush the braising liquid from the slow cooker generously over the surface. Broil on high for 4 to 5 minutes, watching closely, until the top is lacquered, deeply caramelized, and just starting to char at the edges. That sticky, slightly burnished crust is what makes everyone go quiet at the dinner table. Rest for 5 minutes before slicing.

Amber’s Tips for the Best Slow Cooker Pork Belly

Variations on Slow Cooker Pork Belly

Spicy Korean-Style Pork Belly

Swap the Chinese five spice for 2 tablespoons of gochujang paste and add a teaspoon of gochugaru to the braising sauce. The heat from the fermented chili paste builds slowly and pairs beautifully with the fatty pork. Serve over steamed rice with quick-pickled cucumbers on the side.

Lighter Citrus and Herb Version

Replace the honey and brown sugar with orange juice and a tablespoon of maple syrup, and add a few sprigs of fresh thyme to the slow cooker. This version is noticeably brighter and less sweet. Still deeply satisfying but feels a little lighter if you’re feeding people who shy away from richer dishes.

Slow Cooker Pork Belly Tacos

Shred the cooked pork belly instead of slicing it, toss it with the reduced braising sauce, and pile it into warm corn tortillas with pickled red onion, cotija, and cilantro. This is how I use leftovers and honestly it might be even better than the original.

Miso Ginger Pork Belly

Add 2 tablespoons of white miso paste to the braising sauce for an extra layer of umami depth. White miso is mild enough that it doesn’t overpower, it just rounds everything out and makes the sauce taste more complex with almost no extra effort.

What to Serve With Slow Cooker Pork Belly

Steamed jasmine rice: the classic pairing. The rice soaks up the extra glaze and that’s honestly the whole point.
Quick-pickled cucumbers or daikon: the brightness and acidity cut through the richness of the pork belly perfectly. Just thinly slice cucumbers, toss with rice vinegar, a pinch of sugar, and salt. Done.
Simple roasted bok choy: toss halved baby bok choy in sesame oil and roast at 425°F for 12 minutes. It cooks while you’re finishing the pork and makes the whole meal feel complete.
Wonton soup or miso soup: a simple broth-based soup alongside slow cooker pork belly is a restaurant move that takes zero extra work and makes everyone feel fancy.

Storage and Reheating

Leftover slow cooker pork belly keeps in an airtight container in the fridge for up to 4 days. Store the sliced pork separately from any remaining sauce so the crust doesn’t get soggy.

To reheat, place slices in a skillet over medium heat with a splash of the braising sauce or a little chicken broth. Cover for 2 minutes, then uncover and let the sauce reduce back into a glaze for another minute. Microwave works fine in a pinch but the skillet method keeps the texture way better.

For freezing, wrap individual portions tightly in plastic wrap then foil. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Make-ahead option: cook the pork belly completely through the slow cooker step, let it cool, and refrigerate overnight. The fat solidifies on top and lifts off easily, and the flavors actually deepen overnight. Then broil and glaze the next day. Honestly one of the best prep-ahead dinner moves I know.

Frequently Asked Questions About How to Cook Pork Belly in a Slow Cooker

Do you need to sear pork belly before putting it in the slow cooker?

You don’t have to, but you absolutely should. Searing builds a caramelized crust through the Maillard reaction that adds deep, complex flavor the slow cooker alone can’t create. It takes five extra minutes and makes a noticeable difference in both texture and taste. Skip it only if you’re really in a time crunch.

How long does it take to cook pork belly in a slow cooker?

Plan for 6 to 7 hours on the LOW setting or 3.5 to 4 hours on HIGH. Low and slow produces noticeably more tender results because the fat renders gradually without the muscle fibers tightening. I always recommend the low setting if you have the time, it’s worth the wait.

Should I cook pork belly skin-side up or down in the slow cooker?

Place the pork belly meaty side down in the slow cooker. This keeps the meat immersed in the braising liquid where it gets the most benefit. The fat cap and skin on top will self-baste as they slowly render, which bastes the meat below naturally throughout the cooking process.

Can you overcook pork belly in a slow cooker?

Yes, you can. If you cook pork belly too long, especially on HIGH, the collagen breaks down too far and the meat can turn mushy rather than tender. Stick to the recommended times. On LOW, 7 hours is the sweet spot, don’t push past 8 hours or texture starts to suffer.

What cut of pork belly should I use for slow cooker pork belly?

Look for a skin-on, bone-free slab of pork belly about 1 to 1.5 inches thick. Ask your butcher if you’re unsure, they’ll know exactly what you need. Skin-on gives you more flavor and better texture after the broil step. Asian grocery stores almost always have great-quality pork belly at excellent prices.
