How To Make Spicy Delicious Kimchi Jjim At Home

I want to tell you something about kimchi jjim that most recipes won’t lead with: this dish is better with old kimchi. The kind that’s been sitting in your fridge for weeks, gone funky and sour, the kind you’ve been side-eyeing and wondering what to do with. That kimchi is not a problem. That kimchi is the whole point.

Kimchi jjim (김치찜) is Korean braised kimchi — a slow-cooked, deeply savory dish where aged kimchi and pork belly are simmered together until the kimchi goes silky, the pork falls apart, and the braising liquid reduces into something you’ll want to spoon directly over a bowl of rice. It sits in a completely different category from kimchi-jjigae (kimchi stew) — less broth, more concentration, more depth. It’s the difference between a light soup and a full braise.

I’ve made this a lot. I’ve also messed it up. Let me save you the trial-and-error.

What Is Kimchi Jjim, Exactly?

Kimchi jjim literally translates to “steamed kimchi,” but in practice it’s a braise — long, slow, covered cooking in a small amount of liquid. The result is intensely flavored kimchi that’s gone completely tender, pork that’s melt-in-your-mouth, and a thick, spicy, tangy sauce that clings to everything.

It’s related to kimchi jjigae (kimchi stew) but they’re not the same. Jjigae has broth — you eat it as a soup alongside rice. Jjim has almost no broth left by the end — you eat it as a hearty banchan (side dish) or a main, with rice serving as the vehicle for all that concentrated sauce.

If kimchi jjigae is Monday-night comfort food, kimchi jjim is Sunday cooking. Slower, richer, and worth every minute.

Why You Need Old Kimchi for This Recipe

Fresh kimchi won’t work here. I know that sounds prescriptive, but I’ve tested it — the result is flat, thin, and slightly raw-tasting. Kimchi jjim depends on the deep, fermented funk that only comes with aged kimchi: the kind that’s been fermenting at least 3–4 weeks, ideally longer.

The science is simple: fermentation develops lactic acid and complex amino acids that can’t be rushed. When that aged kimchi hits a hot pot with fatty pork and braises for an hour, those compounds mellow and sweeten into something completely transformed. Fresh kimchi just doesn’t have the building blocks for that transformation.

If your kimchi is on the fresher side, add 1 tablespoon of rice vinegar to compensate. Not the same, but it’ll get you 70% of the way there.

Ingredients You Need

Serves 4 as a main with rice, 6 as a banchan

For the braise

• 800g (about 1.75 lbs) aged napa cabbage kimchi — whole-leaf or pre-cut, either works. Whole-leaf is traditional and looks beautiful on the plate.
• 500g (about 1 lb) pork belly, cut into thick slices or kept in 3–4 inch chunks
• ½ cup kimchi brine — scoop it right from the jar. This is liquid gold for the braising base.
• 1 cup rice water (water from the second or third rinse of raw rice) — this is the traditional Korean braising liquid. It thickens the sauce subtly and adds a clean, starchy backbone. Plain water works if you’re not cooking rice simultaneously.
• ½ medium onion, sliced

For the sauce

• **2 tablespoons gochugaru** (Korean red pepper flakes) — this is non-negotiable. Gochugaru has a specific fruity heat that regular chili flakes can’t replicate.
• 1 tablespoon gochujang (Korean fermented chili paste)
• 1 tablespoon soy sauce
• 1 tablespoon fish sauce — adds depth. Vegetarians: swap for a teaspoon of Yondu or additional soy sauce.
• 1 tablespoon sesame oil
• 1 tablespoon sugar — balances the sourness of aged kimchi. Don’t skip it.
• 4 garlic cloves, minced
• 1 teaspoon grated fresh ginger
• Optional: ½ tablespoon doenjang (Korean fermented soybean paste) — this is the secret weapon I picked up from traditional Korean recipes. It doesn’t make the dish taste like soybean paste. It rounds the sourness, deepens the umami, and gives the sauce a fullness you can’t get otherwise. Highly recommend.

Finishing

• 2 green onions, cut into 2-inch pieces
• 1 fresh red or green chili, sliced (optional, for garnish and heat)

Equipment

• A wide, heavy-bottomed pot or braiser — I use a 4-quart Dutch oven. You want something wide enough that the kimchi and pork can lie relatively flat, which ensures even cooking. A Korean dolsot (stone pot) works beautifully here too.
• Kitchen scissors — for cutting the braised kimchi into bite-size pieces at the table, Korean-style.

How to Make Kimchi Jjim, Step by Step

Step 1: Parboil the pork (10 minutes, but don’t skip it)

Place the pork belly in your pot and cover with cold water. Add a few slices of fresh ginger. Bring to a boil and cook for 10 minutes — you’ll see grey scum rising to the surface. This is myoglobin and impurities, and getting rid of it is what prevents the finished dish from tasting gamey.

Drain, rinse the pork under cold water, and scrub the pot clean. This step seems fussy but it takes 10 minutes and makes a real difference to the final flavor.

Step 2: Build the braising base

In a small bowl, combine the gochugaru, gochujang, soy sauce, fish sauce, sesame oil, sugar, garlic, ginger, and doenjang (if using). Mix into a paste.

In your clean pot, lay the sliced onion across the bottom — this acts as a buffer that prevents the kimchi from scorching. Place the parboiled pork on top of the onions.

Step 3: Add the kimchi and sauce

Layer the kimchi over and around the pork. Pour in the kimchi brine and rice water. Spoon the sauce paste over everything.

Don’t stir yet. You want distinct layers at the start.

Step 4: Braise

Cover and bring to a boil over medium-high heat — this should take about 5–6 minutes. Once you hear it properly bubbling, reduce to medium-low and simmer for 50 minutes to 1 hour, stirring gently every 15–20 minutes.

You’re looking for: kimchi that’s gone completely limp and translucent, pork that gives easily when poked, and a sauce that’s thickened and turned a deep brick red. The liquid level will reduce significantly — that’s correct.

If the pot is getting dry before the pork is tender, add water ¼ cup at a time.

Step 5: Add finishing garnish

In the last 5 minutes, tuck in the green onions and sliced chili. Replace the lid and let them steam through without losing their color.

Step 6: Serve

Transfer to a serving dish or bring the pot straight to the table. Use kitchen scissors to cut the kimchi into manageable pieces. Serve alongside steamed short-grain rice — white or Korean purple multigrain rice if you have it. The sauce should be spooned over the rice liberally. That’s the whole point.

If you’re building out a full Korean spread, quick cucumber kimchi (oi sobagi) is the ideal side — the cool crunch and bright acidity cut straight through the richness of the braised pork in a way that nothing else does. A fried egg with a runny yolk works the same way. For a more substantial table — dinner guests, a weekend spread — Korean glass noodles (Japchae) alongside this braise is one of my favorite combinations on the site: the chewy, sesame-dressed noodles and the concentrated kimchi sauce are made for each other.

The Mistakes I Made (So You Don’t Have To)

Using fresh kimchi. Already covered — but worth repeating because it’s the single biggest variable. If your kimchi is fresh, this dish won’t taste like kimchi jjim.

Not parboiling the pork. I skipped this once and the finished braise had an undertone that I can only describe as barnyard. The 10-minute parboil is not optional.

Too high heat. Kimchi jjim is a low-and-slow dish. If your heat is too high, the kimchi on the bottom scorches before the pork is tender. Medium-low, covered, patient.

Skipping the doenjang. I know it sounds odd to add fermented soybean paste to a braised kimchi dish. Try it once and you’ll understand. It’s subtle but the difference is real.

Kimchi Jjim Variations Worth Trying

With tofu: Add a block of firm tofu (cut into thick slabs) in the last 20 minutes. It absorbs the braising liquid beautifully and makes this more of a complete one-pot meal.

Spam or tuna version: A classic Korean pantry workaround — dice one can of Spam or add a can of oil-packed tuna in place of the pork. The tuna version in particular is lighter and cooks faster (30 minutes instead of an hour).

Pork ribs: Swap pork belly for bone-in pork ribs. Parboil them for 20–30 minutes first, then braise with the kimchi. The bones add extra body to the sauce.

Vegetarian: Use firm tofu and mushrooms (king oyster or shiitake work well), replace fish sauce with Yondu or soy sauce, and skip the doenjang or replace with white miso. Not traditional, but genuinely good.

Storage and Reheating

Refrigerator: Store in an airtight container for up to 3–4 days. The flavor deepens overnight — day-two kimchi jjim is genuinely better than day-one.

Freezer: Freeze for up to 1 month. The kimchi texture will soften further upon thawing, which is actually fine in a braise. Defrost in the fridge overnight and reheat gently on the stovetop.

Reheating: Add a splash of water, cover, and warm over medium-low heat. Don’t rush it.

One more thing: leftover kimchi jjim the next day is genuinely better — the sauce thickens overnight and the flavors meld in a way that’s hard to explain until you experience it. If you have leftover braised kimchi, it’s spectacular folded through freshly cooked rice with a fried egg on top. And if this whole recipe has you thinking more seriously about your kimchi game, our 7-day kimchi fermentation guide is the place to start — it’s the single skill that will make every Korean kimchi recipe on this site better. On the quicker end of the Korean pantry spectrum, the kimchi soup (kimchi-jjigae) uses most of the same ingredients and takes under 30 minutes — a good weeknight option when you don’t have an hour to braise.

Frequently Asked Questions

What’s the difference between kimchi jjim and kimchi jjigae? Kimchi jjigae is a stew — more liquid, faster to cook, a brothy dish you eat like soup alongside rice. Kimchi jjim is a braise — almost no liquid remains by the end, slower cooking, and the flavors are far more concentrated. They use many of the same ingredients but produce completely different results.

Can I make kimchi jjim without pork? Yes — see the vegetarian variation above. The dish loses some richness without the rendered pork fat, but tofu and mushrooms make a legitimate substitute. The key is still using aged kimchi and cooking it long enough for the flavors to develop.

My kimchi is fresh — can I still make this? You can, but add 1 tablespoon of rice vinegar and expect a lighter, less complex result. The dish really depends on the amino acids and lactic acid in well-fermented kimchi — fresh kimchi hasn’t had time to develop those compounds. If you want to make this properly, try our 7-day kimchi fermentation plan first and come back to this recipe in a week.

What cut of pork is best for kimchi jjim? Pork belly is the classic choice for its fat content — the rendered fat emulsifies into the braising liquid and creates that rich, glossy sauce. Pork shoulder (pork butt) is leaner and works well if you want less fat. Bone-in pork ribs add extra gelatin and body. I don’t recommend pork loin — it dries out.

How do I know when it’s done? The kimchi should look completely limp and translucent — it loses that bright red opacity and goes almost silky. The pork should yield without resistance when poked with chopsticks. The sauce should be thick and coating, not watery. If you’re hitting an hour and the pork isn’t tender yet, it’s fine to go another 15–20 minutes.

Where do I find gochugaru if my regular grocery store doesn’t carry it? Any Korean or Asian grocery store will have it. Online, gochugaru is easy to find — look for the Taekyung or Haechandle brands, both are reliable for this dish. Do not substitute regular crushed red pepper flakes — the flavor profile is completely different.
