In a large, heavy-bottomed pot or Dutch oven, heat oil over medium-high heat. Add pork belly pieces and sear on all sides until golden brown, about 3-4 minutes per side. Work in batches if necessary to avoid overcrowding.
Reduce heat to medium and add sliced onion, minced garlic, and ginger. Sauté for 2-3 minutes until fragrant.
In a bowl, combine all braising sauce ingredients and mix well to create a smooth paste.
Return all pork to the pot and add the chopped kimchi and kimchi juice. Pour the braising sauce over everything and stir gently to combine.
Add just enough water to barely cover the ingredients (about 1-1½ cups). Bring to a boil, then reduce heat to low.
Cover and simmer for about 45 minutes, stirring occasionally to prevent sticking.
Remove the lid and continue to simmer for another 30 minutes, allowing the sauce to reduce and thicken. The pork should be very tender and the sauce glossy.
During the last 5 minutes, add the green onion pieces and gently stir in.
Remove from heat and drizzle with sesame oil. Garnish with toasted sesame seeds and additional sliced green onions.
Let rest for 5 minutes before serving with steamed rice.
Notes
RECIPE TIPS
Use well-aged kimchi (at least 2 weeks old) for the best depth of flavor
Don't rush the braising process – low and slow is key for tender pork
Skim off excess fat from the surface during braising if desired
The sauce should reduce to a thick, glossy consistency
For more balanced sweetness, don't skip the grated pear
Allow the dish to rest before serving to let the flavors settle
