Korean Marinated Pork Belly Recipe: Sweet and Savory Grill Masterpiece

This dish brings the bold flavors of Korean BBQ to your home grill. The marinade combines sweet, savory, and umami elements that transform pork belly into a tender, caramelized masterpiece.

I developed this method after years of perfecting pork dishes at The Smoky Pig. The key is in the balance—soy sauce for saltiness, brown sugar for caramelization, and garlic for depth. Let it marinate overnight for maximum flavor penetration.

When grilled over high heat, the sugars in the marinade create a sticky, glossy crust while the fat renders out, leaving the meat juicy and tender. The aroma alone will draw a crowd.

Serve with rice, kimchi, and lettuce wraps for an authentic experience. This technique works for any cut of pork, but belly is the star.

The pork belly is non-negotiable here. Look for skin-on cuts at Korean markets or Costco—they render better and hold shape on the grill. Asian pear might seem unusual, but it’s a traditional tenderizer (Bosc or Anjou work if you can’t find Asian). The soy sauce should be Korean brands like Jin or Sempio for authentic flavor. Avoid pre-cut pork belly; it dries out faster.

No gochujang? Sriracha mixed with 1 tsp miso paste gets you close. Substitute the Asian pear with 1/4 cup grated apple or pineapple (same tenderizing effect). Brown sugar can be swapped for coconut sugar or maple syrup, but adjust sweetness to taste. For a milder flavor, reduce the garlic by half and add extra green onions.

Marinate the pork belly for at least 4 hours, but overnight is ideal. Store marinated meat in the fridge for up to 2 days. Cooked leftovers keep for 3-4 days and reheat well on a skillet or microwave (cover to retain moisture).

Step-by-Step Instructions for Korean Marinated Pork Belly

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Pork Belly Marinade

In a large bowl, combine the 0.5 cup soy sauce, 0.5 cup brown sugar, minced 8 cloves garlic cloves, grated 0.5 whole Asian pear, 2 tbsp sesame oil, 2 tbsp rice vinegar, and 2 tbsp gochujang. Whisk until the brown sugar dissolves completely and the mixture is smooth.

The Asian pear adds natural sweetness and enzymes that tenderize the pork belly. I always use low-sodium soy sauce here to balance the saltiness without overpowering the other flavors. Let this marinade sit for 5 minutes to allow the flavors to meld before adding the pork.

Step 2: Marinate the Pork Belly

Add the 2 lb pork belly (cut into 1/2-inch slices) to the marinade, ensuring each piece is fully coated. Cover the bowl with plastic wrap and refrigerate for at least 4 hours, though overnight is ideal for maximum flavor penetration.

I massage the marinade into the pork belly occasionally during the first hour to ensure even distribution. The pork belly should turn slightly translucent at the edges when it’s fully marinated. Don’t skip the marinating time—this is what gives the dish its signature depth of flavor.

Step 3: Grill the Marinated Pork Belly

Preheat your grill to medium-high heat (about 375°F). Lightly oil the grates with the 1 tbsp cooking oil to prevent sticking. Remove the pork belly from the marinade (reserve the marinade) and grill for 4-5 minutes per side until caramelized and slightly charred at the edges.

Watch for flare-ups from the sugar in the marinade. If they occur, move the pork belly to a cooler part of the grill temporarily. The pork belly is ready to flip when it releases easily from the grates and has developed a deep golden-brown crust.

Step 4: Glaze and Garnish

While the pork belly grills, bring the reserved marinade to a boil in a small saucepan. Reduce heat and simmer for 3-5 minutes until it thickens into a glaze. Brush this glaze over the pork belly during the last 2 minutes of grilling for an extra layer of flavor.

Transfer the pork belly to a serving platter and sprinkle with the thinly sliced 4 whole green onions and toasted 2 tbsp sesame seeds. Let it rest for 5 minutes before serving to allow the juices to redistribute. The final dish should have a glossy sheen with visible char marks.

Make-Ahead Tips for This Dish

Marinade Prep Ahead

Mix the marinade up to 2 days in advance and store it in an airtight container in the fridge. The flavors meld beautifully over time, especially the Asian pear and gochujang. I often make double batches at The Smoky Pig. 💡

Pork Belly Storage

For best results, slice the 2 lb pork belly into 1/2-inch pieces before marinating. Store the marinated pork in a sealed container for up to 2 days in the fridge. The sugar in the marinade helps preserve the meat.

Freezing Option

You can freeze raw marinated pork belly for up to 3 months. Portion it into freezer bags, removing as much air as possible. Thaw overnight in the fridge before grilling. I learned this trick during busy weeks at the restaurant.

Partial Cooking

Par-cook the pork belly on the grill for 2 minutes per side, then refrigerate for up to 24 hours. Finish grilling just before serving. This works great for meal prep—just warm through and glaze.

Glaze Make-Ahead

Prepare the glaze separately by simmering the marinade for 5 minutes until thickened. Store in a jar for up to 1 week. Brush on during the last 2 minutes of grilling for that restaurant-quality finish.

Reheating Tips

Gently reheat cooked pork belly in a skillet over medium-low heat with a splash of water. Cover to retain moisture. Microwave works too—use 30-second intervals and check frequently. 🔥
