Gochujang is one of the foundational flavors of Korean cuisine — a thick, deep-red fermented paste made from red chili peppers, glutinous rice, fermented soybeans, and salt. Unlike fresh chili sauces, gochujang has a complex, slightly sweet, deeply savory character that comes from months of fermentation. It is not just hot — it is fermented-hot, with layers of umami that make it a natural glaze base for fatty proteins like pork ribs.
The method here is deliberate. The ribs are slow-braised until fall-off-the-bone tender, then glazed and finished under a broiler that caramelizes the sugars in the gochujang into something lacquered and slightly charred. The result is ribs that are simultaneously yielding and crispy, deeply flavored and sticky, with just enough heat to cut through the richness of the pork.
Ingredients
Understanding gochujang
Gochujang varies significantly in heat level between brands. Korean brands — Chungjungone and Haechandle are the most widely available outside Korea — are typically labeled by spice level (mild, medium, hot). For ribs, a medium heat level gives the right balance. The paste should be deep red, thick, and slightly fragrant. Once opened, it keeps refrigerated for months.
Do not substitute gochujang with any other chili paste without understanding the difference. Sriracha is much thinner and lacks fermented depth. Sambal oelek has no sweetness. Harissa is North African and profiles completely differently. If gochujang is unavailable, the closest substitution is a mixture of red miso paste and Korean chili flakes (gochugaru), but the fermented complexity will be reduced.
Remove the membrane — non-negotiable
Before anything else, flip the ribs bone-side up and locate the silver membrane that covers the bone side. This tough, papery layer is the single biggest enemy of tender ribs — it blocks the braising liquid and seasoning from penetrating the meat, and stays chewy even after hours of cooking. Use a butter knife to loosen a corner, grip it firmly with a paper towel (for traction), and pull it off in one clean piece. It usually comes off intact. If it tears, work in sections.
The oven braise: low and slow
Season the ribs generously with salt on both sides. Place them meat-side down in a deep roasting pan. Add water or light stock, soy sauce, and a splash of rice wine or dry sherry to cover the bottom of the pan by about 2cm — this creates the steam environment that gently braises the ribs from below. Cover tightly with foil, sealing all edges to trap steam.
Cook in a 150°C oven for 2.5 to 3 hours. The low temperature is the key — it gives collagen time to dissolve into gelatin without the meat seizing or drying out. The ribs are ready when the meat has pulled back from the bone ends by about 1cm and a skewer passes through the thickest part with no resistance. If you pull back the foil and the meat is still firm, reseal and give it another 30 minutes. Overcooked is better than undercooked here — the glaze step will add texture back.
Build the gochujang glaze
While the ribs braise, combine gochujang, soy sauce, honey, rice wine vinegar, sesame oil, minced garlic, grated ginger, and brown sugar in a small saucepan. Place over low heat and simmer 5 minutes, stirring constantly. The glaze should thicken slightly and turn glossy. It will be very thick — that is correct. Taste it: it should be sweet, spicy, fermented, and deeply savory. Adjust with more honey (sweeter), more vinegar (sharper), or more gochujang (hotter) to your preference.
The broil finish: caramelization is the goal
Remove the ribs from the oven and carefully pour off the braising liquid (save it). Pat the ribs lightly dry. Brush the gochujang glaze generously over both sides — do not be shy, a thick coat is what creates the lacquered finish. Switch the oven to its highest broil setting and move a rack to the upper position. Return the ribs and broil 4 to 5 minutes, watching closely. You want the glaze to caramelize, bubble, and char slightly at the edges. This browning is Maillard and caramelization reactions happening simultaneously — it is the difference between good ribs and exceptional ribs. Pull them the moment the edges begin to look properly charred.
Serving
Scatter toasted sesame seeds and sliced spring onions over the ribs immediately. Serve with steamed white rice, kimchi, and pickled daikon. The ribs can also be cut into individual pieces before broiling for easier serving. Leftovers reheat well in a 180°C oven for 10 minutes with an extra brush of glaze — the second caramelization is almost as good as the first.
