Haemul pajeon is Korea's great rainy-day dish — a broad, golden pancake built on a lattice of whole green onions and studded with shrimp, squid, and mussels, crisp and lacy at the edges while staying savory-chewy at the center. The name says it plainly: haemul (seafood) pa (green onion) jeon (pan-fried). Good pajeon depends on restraint and temperature: a thin batter made with ice-cold water and a little rice flour, just enough to bind the onions, fried in generous oil that's properly hot. Tradition holds that the sizzle of pajeon in the pan sounds like falling rain, which is why Koreans crave it — with a bowl of cloudy makgeolli rice wine — the moment the weather turns.
Serves 4
Whisk the flour, rice flour, egg, ice-cold water, salt, and garlic powder until mostly smooth — a few small lumps are fine and overmixing develops gluten that makes the pancake bready. The batter should run off the whisk like thin cream.
Ice-cold water is the crispness secret: it delays gluten formation and creates a lighter, crunchier crust, exactly as in tempura.
Stir together the soy sauce, rice vinegar, sesame oil, and sesame seeds in a small bowl and set aside. The sharp, tangy sauce is the essential counterpoint to the rich fried pancake — make it first so it's ready the moment the pajeon comes off the heat.
Heat 2 tablespoons of oil in a large non-stick or well-seasoned skillet over medium-high heat until it shimmers. Pajeon is shallow-fried, not griddled — generous oil and real heat are what produce the lacy golden edges.
Lay the halved green onions in a single tight layer across the pan, alternating white and green ends so the pancake is even. The onions are the structure of pajeon, not a flavoring — they form the actual body of the pancake.
Let the onions sizzle alone for 30 seconds before the batter goes on; lightly charred onions taste far sweeter.
Pour half the batter slowly and evenly over the green onions, using just enough to barely cover and connect them. A thin batter layer is the goal — pajeon should be a crisp onion lattice held together by batter, not a thick flour pancake with onions lost inside.
Scatter the chopped seafood, julienned carrot, and sliced chili evenly over the wet batter, pressing them in gently, then drizzle the remaining batter over the top to anchor everything in place. Pat dry any watery seafood first so it doesn't make the center gummy.
Cook 4–5 minutes, pressing down occasionally with a spatula, until the bottom is deeply golden and the edges look crisp and lacy. Flip in one confident motion — or invert the pancake onto a plate and slide it back into the pan if it's too large to flip cleanly.
Don't rush the first side; flipping too early is how pajeon tears and seafood scatters.
Drizzle the last tablespoon of oil around the edges so it runs underneath, and cook 4 more minutes until the second side is golden and the seafood is fully cooked. Pressing with the spatula now maximizes contact and crunch on the finished side.
Slide the pancake onto a board, cut into wedges or squares with a knife or kitchen scissors, and serve immediately while the edges still crackle, with the dipping sauce alongside. In Korea, a bowl of cold makgeolli is the canonical companion.
Ice-cold water in the batter and a properly hot, well-oiled pan are the two pillars of crispy pajeon.
Use less batter than feels right — the green onions are the structure, and thick batter makes a doughy pancake.
Press the pancake down with a spatula while it cooks to maximize crisp contact with the pan.
Pat the seafood very dry; watery squid or thawed shrimp is the most common cause of a gummy center.
Two smaller pancakes are easier to flip and crisp better than one giant one — split the recipe if your pan is under 28cm.
Kimchi-jeon: replace the seafood with well-squeezed chopped kimchi and a spoonful of its juice in the batter.
Add a few drops of gochujang or gochugaru to the dipping sauce for heat.
Dongnae pajeon, the Busan style: finish by pouring a beaten egg over the top before flipping for a richer pancake.
Vegetarian: swap seafood for shiitake mushrooms, zucchini, and extra carrot.
Best straight from the pan while the edges crackle. Refrigerate leftovers up to 2 days and re-crisp in an oiled skillet over medium heat — the microwave turns pajeon limp and rubbery.
Jeon — savory pan-fried foods — have centuries of history in Korean royal and home cooking, with pajeon a beloved everyday member of the family; the seafood-loaded dongnae pajeon of Busan is the most famous regional version. Korean folk wisdom links pajeon to rainy weather, claiming the sizzle of batter in oil echoes the sound of rainfall, and to this day pajeon-and-makgeolli sales famously spike when it rains.
Easily — the green-onion base is the soul of the dish, so simply omit the seafood or replace it with sliced shiitake or oyster mushrooms, zucchini matchsticks, or thin strips of firm tofu. Keep everything well dried so the center crisps properly. The result is closer to plain pajeon, a classic in its own right, and the same soy-vinegar dipping sauce works perfectly.
Usually one of four things: batter too thick (it should pour like thin cream), water not cold enough, the pan underheated or under-oiled, or wet seafood leaking moisture into the center. Pajeon is shallow-fried — use the full amount of oil, get it shimmering before the onions go in, and add extra oil around the edges after flipping.
Makgeolli is Korea's milky, lightly fizzy unfiltered rice wine, gently sweet and tangy at around 6% alcohol. Its cool creaminess against hot, oily, crispy pancake is one of Korean food culture's most cherished pairings — especially on rainy days, when tradition says the sound of frying pajeon mimics the rain. Look for it at Korean markets; serve it cold, shaken gently before pouring.
Frozen seafood mix is completely standard for pajeon, even in Korea — just thaw it fully, then drain and pat it aggressively dry, because the thawing liquid is the enemy of a crisp pancake. Chop larger pieces so they distribute evenly and cook in the pancake's short frying time. Fresh shrimp and squid give slightly better texture but the difference is modest.
