The pork belly is non-negotiable here. Skin-on, high-fat slabs from Whole Foods or local butchers yield the crispiest results. Avoid pre-sliced—cutting your own ensures uniform thickness for even cooking. Look for pieces with consistent fat-to-meat ratios (about 50/50). For the soy sauce, Kikkoman low-sodium provides the cleanest flavor without overpowering saltiness.

Need to swap gochujang? Sriracha mixed with a teaspoon of miso gets you close. Brown sugar can be dark brown for deeper molasses notes. Honey substitutes: maple syrup or agave at one-to-one, but expect slightly different glaze consistency. No rice vinegar? Apple cider vinegar works in a pinch, though the flavor profile shifts slightly.

Pork belly keeps raw in the fridge for 3-4 days or frozen for 6 months. The glaze can be made 2 days ahead and reheated gently. Leftovers (if any exist) reheat beautifully—crisp the slices under a broiler for 2-3 minutes to restore texture.

Step-by-Step Instructions for Barbecue Pork Belly Slices

Achieve restaurant-quality crispy edges and a sticky glaze with these precise techniques.

Step 1: Prepare and Season the Pork Belly

Pat the 2 lb Pork Belly slices completely dry with paper towels to ensure maximum crispiness. This step is non-negotiable—any residual moisture will steam the skin instead of allowing it to crisp. Season both sides aggressively with 2 tsp Kosher Salt and 1 tsp Black Pepper, pressing the seasoning into the meat so it adheres well.

The pork belly should be cut into 1-inch slices as specified in the ingredients. I use Diamond Crystal kosher salt for its clean flavor and consistent texture. Let the seasoned slices sit at room temperature for 20 minutes to allow the salt to penetrate the surface, enhancing both flavor and texture.

Step 2: Create the Asian Barbecue Glaze

In a saucepan over medium heat, combine 0.5 cup Light Brown Sugar, 0.25 cup Honey, 0.33 cup Soy Sauce, 2 tbsp Rice Vinegar, 1 tbsp Gochujang, 1 tbsp Fresh Ginger, and 4 cloves Garlic Cloves. The low-sodium soy sauce ensures the glaze doesn’t become overwhelmingly salty as it reduces.

Simmer the mixture for 8-10 minutes, stirring frequently, until it thickens enough to coat the back of a spoon. The glaze should turn a deep amber color and develop a sticky consistency. Remove from heat and stir in 1 tbsp Sesame Oil for depth. This glaze will caramelize beautifully on the pork belly during roasting.

Step 3: Roast the Pork Belly to Crispy Perfection

Preheat your oven to 400°F. Heat 1 tbsp Vegetable Oil in a large oven-safe skillet over medium-high heat. Sear the pork belly slices for 3-4 minutes per side until the edges begin to turn golden brown. This initial sear builds a flavor foundation and starts the crisping process.

Transfer the skillet to the preheated oven and roast for 20-25 minutes. Halfway through, brush the pork belly generously with the prepared glaze. The high heat will render the fat and create a crispy exterior while the glaze caramelizes. The slices are done when the edges are deeply browned and crispy and the internal temperature reaches 195°F.

Step 4: Finish and Garnish for Serving

Remove the pork belly from the oven and brush with the remaining glaze. Let it rest for 5 minutes to allow the juices to redistribute. Thinly slice the 4 whole Green Onions and toast the 1 tbsp Sesame Seeds in a dry pan over medium heat for 1-2 minutes until fragrant and lightly golden.

Garnish the pork belly slices with the toasted sesame seeds and sliced green onions. The contrast of the crispy pork belly, sticky glaze, and fresh garnishes creates a perfect balance of textures and flavors. Serve immediately while hot and crispy for the best experience.

Health Benefits of barbecue pork belly slices

Rich Protein Source

This dish packs a serious protein punch with 2 lb pork belly providing about 50 grams of protein per serving. Protein is essential for muscle repair and growth, making this a satisfying meal. I always feel energized after enjoying a portion. 💪

Healthy Fats for Energy

The fat in pork belly isn’t just flavor—it’s a source of monounsaturated and saturated fats that provide sustained energy. While moderation is key, these fats help your body absorb fat-soluble vitamins like A, D, E, and K from other foods in your meal.

B Vitamin Boost

Pork belly is rich in B vitamins, particularly B1, B2, B6, and B12. These vitamins play crucial roles in metabolism, red blood cell production, and nervous system function. A serving delivers a significant portion of your daily B12 needs.

Iron and Zinc Content

You’ll get a good dose of iron and zinc from this recipe, minerals that support immune function and wound healing. The iron in pork belly is heme iron, which your body absorbs more easily than non-heme iron from plant sources. 💛

Collagen for Skin Health

The slow cooking process breaks down collagen in the pork belly into gelatin, which supports skin elasticity and joint health. I notice my skin looks more radiant when I include collagen-rich foods in my diet regularly.

Energy from Natural Sugars

The glaze contains light brown sugar and honey, providing quick energy from natural carbohydrates. While these should be consumed in moderation, they offer a better alternative to processed sugars in many store-bought sauces.
