Gamjatang (감자탕): Korean Spicy Pork Bone Stew Recipe

Tender pork backbone, soft potatoes, and a fiery, deeply savory broth Korea's most satisfying late-night stew.

If you've ever ended a long night in Seoul with a bubbling pot of something spicy, messy, and deeply restorative, you've probably eaten gamjatang. It's Korea's ultimate hangover food a fiery pork bone stew loaded with potatoes, vegetables, and a broth so rich and savory that it feels like it's putting you back together from the inside out.

Gamjatang literally means "potato soup" (gamja = potato, tang = soup), but the real star is the pork backbone. It's simmered for hours until the meat is fall-off-the-bone tender and the broth is deep, spicy, and collagen-rich. The potatoes soak up all that flavor and turn soft and buttery. And the whole thing is eaten with rice, soju, and a lot of napkins.

It's not a quick weeknight dish. It's a project but a deeply rewarding one. And once you've made it at home, you'll understand why gamjatang has a cult following in Korea and among Korean food lovers worldwide.

This guide covers everything: what gamjatang actually is, the regional styles, how to build the broth, and a detailed step-by-step recipe that gets you as close to a Korean gamjatang restaurant as you can get at home.

What Is Gamjatang, Exactly?

Gamjatang is a Korean spicy pork bone stew made with pork backbone (or neck bones), potatoes, and a variety of vegetables, simmered in a broth seasoned with gochugaru (Korean red chili flakes), gochujang (red chili paste), soybean paste (doenjang), garlic, ginger, and perilla seeds. It's spicy, savory, and deeply rich, with a broth that's thick and almost gelatinous from the collagen in the bones.

Despite the name, potatoes aren't actually the main ingredient they were added later as a filling, economical addition. The original dish was all about the pork bones.

There are two main regional styles:

• Seoul-style gamjatang the most common version. Spicy, red broth with pork backbone, potatoes, and vegetables. Often served with perilla seeds and sesame leaves.
• Jeolla-style gamjatang from the Jeolla province. Slightly sweeter and less spicy, with more vegetables and sometimes noodles added at the end.

There's also a close cousin called gamja-tang that's sometimes confused with ppyeo-haejangguk (뼈해장국), a similar pork bone soup that's less spicy and often eaten as a hangover cure. The two are closely related, and the line between them is blurry.

Why This Recipe Works

Most homemade gamjatang fails for one of three reasons: the broth is greasy and cloudy, the pork is tough and dry, or the flavor is flat and one-dimensional. This recipe solves all three:

• A two-stage bone boil the first boil removes impurities and excess fat; the second boil extracts the collagen and flavor. This is what gives gamjatang its rich, clean broth.
• Perilla seeds (deulkkae) these ground seeds are the secret ingredient that gives gamjatang its signature nutty, earthy depth. Don't skip them.
• Potatoes added late adding the potatoes in the last 30 minutes prevents them from turning mushy and disappearing into the broth. They should hold their shape and soak up the flavor.

Ingredients (Serves 4–6)

For the pork bones:

• 1.5 kg pork backbone or neck bones, cut into manageable pieces
• 2 tbsp rice wine (mirin) or cooking sake
• 1 piece ginger, about 2 inches, sliced
• 1 onion, halved
• 1 head of garlic, cloves peeled
• 1 tbsp whole black peppercorns
• 12 cups water

For the seasoning paste:

• 3 tbsp gochugaru (Korean red chili flakes)
• 2 tbsp gochujang (Korean red chili paste)
• 2 tbsp doenjang (Korean soybean paste)
• 2 tbsp soy sauce
• 1 tbsp sugar
• 1 tbsp honey or corn syrup
• 2 tbsp minced garlic
• 1 tbsp grated ginger
• 2 tbsp perilla seed powder (deulkkae garu)
• 1 tbsp sesame oil

For the vegetables:

• 3 medium potatoes, peeled and cut into large chunks
• 1 large onion, cut into wedges
• 1 carrot, cut into thick slices
• 1 cup napa cabbage, cut into pieces
• 4–5 dried shiitake mushrooms, soaked and sliced
• 2 green onions, cut into 2-inch pieces
• 1 handful of sesame leaves (perilla leaves), sliced
• Optional: 1 cup glass noodles (dangmyeon), soaked
• Optional: 1 tbsp whole perilla seeds (for garnish)

Note: If you can't find perilla seed powder, you can substitute with ground sesame seeds, but the flavor will be different. Perilla seeds are what give gamjatang its signature earthy, nutty taste.

Step-by-Step Recipe

Step 1: Clean the Bones

Place the pork bones in a large pot and cover with cold water. Bring to a boil over high heat and boil for 10 minutes. You'll see a lot of grey scum rise to the surface. Drain the bones and rinse them thoroughly under cold water, scrubbing away any remaining impurities. This step is essential for a clean, rich broth.

Step 2: Start the Broth

Return the cleaned bones to the pot. Add the rice wine, ginger, onion, garlic, and peppercorns. Add 12 cups of cold water. Bring to a boil over high heat, then reduce the heat to a gentle simmer. Skim off any foam that rises to the surface during the first 20 minutes.

Step 3: Simmer Low and Slow

Simmer uncovered for 1.5–2 hours, until the pork is tender and the broth is rich and slightly thickened. The bones should look chalky and spent when done. Add more water if the level drops too low you want to end up with about 8 cups of broth.

Broth check: A properly made gamjatang broth should be slightly thick and collagen-rich, not watery. If it's still thin after 2 hours, keep simmering the bones need time to release their gelatin.

Step 4: Make the Seasoning Paste

While the broth simmers, combine the gochugaru, gochujang, doenjang, soy sauce, sugar, honey, minced garlic, grated ginger, perilla seed powder, and sesame oil in a small bowl. Mix well to form a thick, fragrant paste. Set aside.

Step 5: Add the Seasoning and Vegetables

Once the pork is tender, remove the bones from the broth and set them aside to cool slightly. Strain the broth through a fine-mesh sieve into a clean pot, discarding the aromatics. Add the seasoning paste to the broth and stir well. Bring to a simmer. Add the potatoes, onion, carrot, cabbage, and shiitake mushrooms. Simmer for 15–20 minutes, until the vegetables are almost tender.

Step 6: Return the Pork

Pick the meat off the cooled bones and return it to the pot, discarding the bones. Alternatively, return the bones with the meat still attached for a more traditional presentation. Add the green onions, sesame leaves, and glass noodles (if using). Simmer for another 5–10 minutes, until everything is heated through and the noodles are tender.

Step 7: Serve

Ladle the gamjatang into a large shallow pot or individual bowls. Garnish with whole perilla seeds and extra sliced green onions. Serve with steamed rice, kimchi, and pickled radish on the side. In Korea, gamjatang is often eaten with soju the combination is called gamjatang and soju, and it's a late-night ritual.

How to eat gamjatang: Use chopsticks to pull the meat off the bones, and a spoon to eat the broth and vegetables. Dip the meat in a little salt-pepper mixture or ssamjang (fermented bean paste) for extra flavor. Eat with rice, and don't be afraid to get messy gamjatang is a hands-on dish.

Popular Variations to Try

• Ppyeo-haejangguk (뼈해장국) a close cousin that's less spicy and more focused on the broth. Often eaten as a hangover cure.
• Gamjatang with noodles add somyeon (thin wheat noodles) or udon at the end of cooking for a heartier bowl.
• Spicy gamjatang add extra gochugaru and a splash of sriracha for more heat.
• Gamjatang with perilla leaves add more sesame leaves (perilla leaves) at the end for a fresh, herbal note.

Tips for the Best Gamjatang

• Don't skip the first boil. Cleaning the bones is the single most important step for a clean, rich broth.
• Simmer, don't boil. A hard boil makes the broth cloudy and greasy. A gentle simmer gives you a rich, collagen-filled broth.
• Use perilla seeds. They're the secret ingredient that makes gamjatang taste like gamjatang. Don't substitute unless you absolutely have to.
• Add potatoes late. Potatoes turn mushy if cooked too long. Add them in the last 20–30 minutes.
• Serve it hot and messy. Gamjatang is a hands-on dish. Serve it with plenty of napkins and a bowl for the bones.
