Busan Pork Soup Recipe: Spicy Kimchi-Braised Pork in Rich Broth

This Busan pork soup recipe captures the bold flavors of Korea’s coastal city, where spicy kimchi meets tender pork in a deeply aromatic broth. 🌟 The secret lies in slow-braising pork belly until it’s fall-apart tender, then finishing with fermented kimchi for that signature tangy heat.

After years of perfecting this dish—both in my CIA training and at The Smoky Pig—I’ve simplified the technique without sacrificing that restaurant-quality depth.

The broth builds flavor through layering: garlic, ginger, and scallions form the aromatic base, while soy sauce and gochujang create the signature Busan spice profile. Pork belly renders its own fat, enriching the broth as it simmers for hours, while kimchi adds both acidity and umami.

What you’ll end up with is a soup that’s rich, complex, and perfectly balanced—spicy enough to wake up your palate but never overwhelming.

This isn’t just another pork soup; it’s a celebration of Busan’s coastal cuisine, where the sea breeze meets fiery flavors. The result is tender pork that practically melts in your mouth, floating in a broth that’s simultaneously comforting and exciting.

Each spoonful delivers layers of savory, spicy, and umami—proof that authentic comfort food doesn’t require compromise.

Serve with steamed rice to soak up every last drop of that flavorful broth, or pair with a cold beer to cut through the heat. The leftovers only get better as the flavors meld overnight. Let’s make this soup—your taste buds will thank you.

Ingredients for busan pork soup

Six hearty ingredients transform into Busan’s iconic spicy pork soup—rich, tender, and packed with umami.

The pork belly is non-negotiable here—thick-cut, skin-on delivers the best fat render for that signature richness. Costco or your local butcher will have it pre-sliced, but if you’re cutting it yourself, aim for 1-inch thick pieces. The kimchi? Look for bright red, not browned—that’s your sign it’s fresh. H Mart or Korean markets carry the best fermented varieties, but the jarred stuff at regular grocery stores works too. Gochujang is the soul of Busan flavor—Maesilchun or Sinsegae are my go-tos, but any brand with a deep red hue is fine. Skip the powdered stuff, it’s not the same.

No gochujang? Mix 2 tbsp red pepper flakes with 1 tbsp soy sauce for a rough substitute, but trust me, it won’t be identical. Sesame oil is for finishing—toast it first in a dry pan for 30 seconds to deepen the flavor. Brown sugar might sound odd, but it’s essential for balancing the heat. Use packed cups—lightly packed means less sweetness. The broth can be water, but low-sodium chicken broth adds another layer of depth. And if you’re short on time, pre-minced garlic and ginger from the freezer section works just as well as fresh.

This soup tastes even better the next day—flavors meld overnight. Store leftovers in airtight containers for 4-5 days in the fridge, or freeze for 3 months (portion into containers for easy reheating). The pork belly will get even more tender as it sits. For serving, I always keep a bowl of steamed rice ready—it soaks up every last drop of that flavorful broth. And if you’re feeling fancy, garnish with toasted sesame seeds right before serving.

Step-by-step instructions for Busan pork soup

Here's how to make this rich, spicy pork belly soup that balances heat and umami perfectly.

Cut the 2 lb pork belly into 1-inch thick slices, leaving the skin on. Place them skin-side down in a large Dutch oven over medium-low heat. Let them render undisturbed for 10-12 minutes until the fat begins to bubble and the skin turns golden brown.

Here's the thing—don't rush this step. The rendered fat is what creates that luxurious, velvety broth. If you see the fat getting too dark or smoky, reduce the heat slightly. You want it to bubble gently, not smoke aggressively. Once the fat is rendered and the pork is lightly browned, flip the slices and cook for another 5 minutes on the other side.

Remove the pork slices and set them aside. In the same Dutch oven, add 2 cups kimchi (including its juice) and cook over medium heat for 3-4 minutes until the kimchi starts to soften and release its tangy aroma. Stir occasionally to prevent sticking.

Add the 6 cloves minced garlic cloves and 0.5 cup julienned fresh ginger, cooking for another 1-2 minutes until fragrant. Here's where the magic happens: the garlic and ginger should smell pungent and inviting, not burnt. If it starts to darken too quickly, reduce the heat. Now add the 0.25 cup gochujang and stir to combine, letting it meld with the kimchi flavors.

Pour in the 6 cups water and add the 0.5 cup soy sauce, 0.25 cup packed brown sugar, 1.5 tsp salt, and 0.5 tsp black pepper. Bring the mixture to a gentle boil, then reduce heat to low and let it simmer uncovered for 30 minutes. This allows the flavors to meld and the broth to develop depth.

Real talk: this is where patience pays off. The broth should reduce slightly, becoming more concentrated and aromatic. If you notice the broth is too thin, continue simmering uncovered—it'll thicken as it reduces. After 30 minutes, add the pork belly slices back to the pot and simmer for another 20-25 minutes until the pork is fork-tender and easily pulls apart.

Remove the pork slices and shred them into bite-sized pieces using two forks. Return the shredded pork to the broth and stir in the 0.25 cup sliced scallions. Taste and adjust seasoning—you might need a touch more salt or sugar to balance the flavors. The soup should be rich, slightly sweet, and spicy with a deep umami punch.

To serve, ladle the soup over 3 cups steamed white rice in individual bowls. Drizzle each serving with 1 tablespoon toasted sesame oil and sprinkle with 1 tablespoon toasted sesame seeds. The contrast of the warm rice with the hot, spicy broth is what makes this dish truly special.

Perfect pairings for busan pork soup

Kimchi Side Pairings

Busan pork soup’s spicy kick pairs beautifully with fresh, crunchy kimchi sides that cut through the richness. Serve with quick-pickled radishes (thinly sliced daikon or Korean radish in rice vinegar with a pinch of sugar) to add brightness.

I also love a small side of banchan-style cucumber salad—thinly sliced cucumbers tossed with sesame seeds, a splash of vinegar, and a hint of gochugaru for a perfect contrast. 🥬

Rice Variations

While steamed white rice is traditional, try short-grain sushi rice for a stickier texture that soaks up the broth beautifully. For a heartier option, serve over garlic fried rice—the nutty aroma complements the pork’s richness.

My go-to is a mix of both: a base of white rice topped with a scoop of fried rice for extra depth. Don’t forget to toast the rice in the pot with a pat of butter before steaming for that extra aromatic punch!

Drink Pairings

A crisp lagersuch as Hite or Cass (Korean lagers) balances the soup’s spice and richness perfectly. The light, clean finish cleanses your palate between bites. For something stronger, try a soju cocktail—mix equal parts soju and grapefruit juice with ice for a refreshing sipper.

If you prefer wine, a dry Riesling with its citrus notes stands up to the gochujang’s heat while enhancing the umami. 🍺

Garnish Upgrades

Toasted sesame seeds are a must, but elevate the dish further with crispy fried shallots for a nutty crunch. A drizzle of chili crisp (like Lao Gan Ma) adds another layer of heat and texture.

For freshness, top with thinly sliced scallions and a few cilantro leaves—the herbaceous notes brighten the dish. I also like adding a few soft-boiled egg halves on top for extra richness and protein. 🌟

Bread Pairings

Warm Korean mandu (dumplings) make an excellent side—their savory filling contrasts perfectly with the soup’s spice. For a lighter option, serve with garlic toast made from a baguette, brushed with garlic butter, and sprinkled with flaky sea salt.

The crispy bread soaks up the broth beautifully, making every bite more satisfying. If you’re feeling adventurous, try tteokbokki (spicy rice cakes) on the side—they add another layer of heat and texture. 🍞
