Korea's Humble Soybean Classic

Kongbiji Jjigae (콩비지찌개): Korean Puréed Soybean Stew Recipe

A thick, creamy, protein-rich stew made from ground soybeans and aged kimchi the humble peasant dish that became a Korean comfort classic.

There's a Korean stew that doesn't get nearly the attention it deserves. It's not spicy in the way that kimchi jjigae is. It's not as famous as doenjang jjigae. It's not even particularly photogenic. But it's one of the most satisfying, protein-packed, deeply comforting dishes in Korean cuisine. That's kongbiji jjigae.

Kongbiji jjigae is a thick, creamy stew made from ground soybeans traditionally the soy pulp left over from making tofu. It's simmered with aged kimchi, pork, and aromatics until it becomes a rich, hearty, almost porridge-like stew. It's nutty, savory, and deeply filling, and it's one of the best examples of Korean peasant cooking: humble ingredients transformed into something extraordinary.

What makes kongbiji jjigae special is its history. It was born out of necessity when Korean households made tofu, they were left with a byproduct (kongbiji, or okara) that they didn't want to waste. So they simmered it with whatever they had on hand: kimchi, pork, aromatics. The result was a stew that was cheap, filling, and surprisingly delicious.

Today, kongbiji jjigae is still a beloved home-cooked dish, but it's also increasingly available in Korean restaurants and even in canned form for those who want a quick, convenient version. But nothing beats making it from scratch.

This guide covers everything: what kongbiji jjigae actually is, the different regional styles, how to source or make kongbiji, and a detailed step-by-step recipe that gets you a thick, creamy, deeply flavorful stew.

What Is Kongbiji Jjigae, Exactly?

Kongbiji jjigae (콩비지찌개) literally means "soy pulp stew" (kong = soybean, biji = pulp or dregs, jjigae = stew). It's a Korean dish made by simmering ground soybeans or soy pulp with kimchi, pork, and seasonings until the mixture thickens into a creamy, hearty stew.

It's traditionally made with kongbiji the soybean pulp left over after making tofu or soy milk. In Korean, this byproduct is also called biji, and it's the same thing as Japanese okara. Modern cooks often use whole soaked soybeans that are ground fresh, which gives a slightly different texture but a similar flavor.

There are two main regional styles:

• Southern style (Gyeongsangbuk-do and Jeolla) made with kimchi, pork, and gochugaru. Spicy, tangy, and deeply savory. This is the most common version today.
• Northern style kept white and simple, seasoned only with soy sauce and sometimes served with boiled napa cabbage instead of kimchi. Milder and cleaner-tasting.

There's also a version made with pork ribs (dwaeji galbi kongbiji jjigae) that's popular in Gyeonggi Province it's richer and more substantial, almost a meal in itself.

Why This Recipe Works

Most homemade kongbiji jjigae fails for one of three reasons: the stew is too thin and watery, the soybean flavor is raw and bitter, or the whole thing is bland and one-dimensional. This recipe solves all three:

• Soaking the soybeans overnight this softens them so they blend into a smooth, creamy purée. Unsoaked soybeans are hard to grind and produce a gritty, raw-tasting stew.
• Frying the pork and kimchi first this builds a flavor base that infuses the entire stew. The pork fat carries the nutty flavor of the soybeans, and the kimchi adds tang and depth.
• A long, gentle simmer the soybean purée needs time to cook through and thicken. A quick boil leaves it raw-tasting and thin. A 15-minute simmer transforms it into a rich, creamy stew.

Ingredients (Serves 3–4)

For the stew:

• 1 cup dried soybeans (or 2 cups fresh kongbiji/okara)
• 2 cups water (for grinding, if using dried soybeans)
• 150g pork belly or fatty pork shoulder, diced small
• 1 cup aged kimchi (mukeunji), chopped into bite-sized pieces
• 1/4 cup kimchi juice (from the jar)
• 1 small onion, diced
• 2 green onions, chopped
• 1 tbsp minced garlic
• 1 tsp grated ginger
• 1 tbsp gochugaru (Korean red chili flakes)
• 1 tbsp soup soy sauce (gukganjang) or regular soy sauce
• 1 tsp sesame oil
• 1 tsp fish sauce or salted shrimp (optional, for depth)
• 3–4 cups water or anchovy-kelp stock
• Salt and pepper, to taste

For serving:

• Steamed short-grain white rice
• Kimchi and other banchan (side dishes)
• Optional: a drizzle of sesame oil and sesame seeds

Note: If you can't find fresh kongbiji (soy pulp), you can make your own by soaking dried soybeans overnight, blending them with water, and straining the mixture through a cheesecloth or fine-mesh sieve. The pulp left in the cloth is your kongbiji. Reserve the strained liquid (soy milk) for another use.

Step-by-Step Recipe

Step 1: Prepare the Soybeans

If using dried soybeans, rinse them under cold water and soak them overnight (at least 8 hours) in plenty of water. The next day, drain the soybeans and rub them between your fingers to remove as many skins as possible. The skins will float to the top pour them off.

Soybean tip: If you're using fresh kongbiji (soy pulp) instead of dried soybeans, skip this step and simply measure out 2 cups of the pulp. You'll need a bit more stock to achieve the right consistency.

Step 2: Grind the Soybeans

Place the soaked and drained soybeans in a blender with about 2 cups of cold water. Blend for 30 seconds to 1 minute, until you have a smooth, creamy purée. The consistency should be like a thick pancake batter pourable but not watery. Set aside.

Step 3: Fry the Pork and Kimchi

Heat a heavy-bottomed pot over medium-high heat. Add the diced pork and cook for 3–4 minutes, until the fat renders and the meat is lightly browned. Add the sesame oil, minced garlic, and grated ginger, and cook for 1 minute until fragrant.

Add the chopped aged kimchi and the diced onion. Stir-fry for 3–4 minutes, until the kimchi softens and becomes glossy. You'll see it darken slightly and smell a deep, tangy aroma.

Step 4: Add the Liquid and Seasonings

Pour in the water or anchovy-kelp stock, along with the kimchi juice. Add the gochugaru, soup soy sauce, and fish sauce or salted shrimp (if using). Stir well to combine. Bring to a boil, then reduce the heat to a gentle simmer.

Step 5: Add the Soybean Purée

Slowly pour the ground soybean purée into the simmering pot, stirring constantly to prevent lumps. Once all the purée is added, stir well to combine everything evenly. The stew will look thin at this point that's normal.

Consistency check: Kongbiji jjigae should be thick and creamy, like a hearty porridge. If it's too thin after simmering, cook it a little longer to reduce. If it's too thick, add a splash of water or stock.

Step 6: Simmer the Stew

Bring the stew back to a gentle simmer, then cover and cook for 12–15 minutes over medium-low heat. The soybean purée needs time to cook through and thicken. Stir occasionally to prevent sticking, and be careful the purée can splatter as it bubbles.

Step 7: Finish and Serve

Taste the stew and adjust the seasoning add more soy sauce if it needs salt, more kimchi juice if it needs tang, or a pinch of sugar if it's too sour. Add the chopped green onions and simmer for 1 more minute. Serve the kongbiji jjigae bubbling hot, directly in the pot if you're using a ttukbaegi (Korean earthenware pot), with a bowl of steamed short-grain rice on the side. To eat, spoon the stew over your rice, or dip your spoon into the stew and then into the rice.

Popular Variations to Try

• Pork rib kongbiji jjigae (dwaeji galbi kongbiji jjigae) use pork ribs instead of diced pork. Simmer the ribs in the broth first until tender, then add the soybean purée and kimchi. Richer and more substantial.
• Northern-style white kongbiji jjigae skip the kimchi and gochugaru entirely. Use boiled napa cabbage and season only with soy sauce. The result is a clean, mild, nutty stew that lets the soybean flavor shine.
• Vegetarian kongbiji jjigae skip the pork and use mushroom stock instead. Add extra tofu or mushrooms for substance. Still deeply flavorful.
• Spicy kongbiji jjigae add extra gochugaru and a spoonful of gochujang for more heat. For those who like it fiery.
• Kongbiji jjigae with seafood add clams or shrimp along with the kimchi. The brininess of the seafood complements the nutty soybeans beautifully.

Tips for the Best Kongbiji Jjigae

• Soak the soybeans overnight. This is non-negotiable if you're using dried soybeans. Unsoaked beans are hard to grind and produce a gritty, raw-tasting stew.
• Use fatty pork. Pork belly or fatty shoulder adds richness and carries the nutty flavor of the soybeans. Lean pork makes a drier, less flavorful stew.
• Use aged kimchi. The sourness and depth of aged kimchi are essential for the traditional version. Fresh kimchi makes a flat, one-dimensional stew.
• Simmer gently and cover the pot. The soybean purée can splatter as it bubbles. A covered pot keeps your kitchen clean and helps the stew cook evenly.
• Serve with rice. Kongbiji jjigae is meant to be eaten with steamed rice. The plain rice balances the richness of the stew and helps reduce the slightly gritty mouthfeel of the soybean purée.
