Crispy Korean Seafood Pancake (Haemul Pajeon) Recipe

There's a reason Koreans call rainy days pajeon days. Oil hitting a hot pan makes almost the same sound as rain hitting a window, and the smell of scallions and seafood crisping up is the kind of thing that pulls the whole house into the kitchen.

Most homemade versions come out soft and a little sad, though, closer to a soggy omelette than the shattering, golden crust you get at a Korean restaurant. The fix has nothing to do with a fancy pan and everything to do with how cold your batter stays and how much oil you're willing to use.

Golden, blistered edges are the whole point of a good haemul pajeon.

About thirty minutes total gets you one large pancake that splits easily into four wedges, and a single nonstick skillet is the only equipment this really asks for.

Ingredients

• 1 cup all-purpose flour
• 1/2 cup potato starch, or cornstarch as a substitute
• 1/2 teaspoon salt
• 1 cup ice-cold water, or chilled seafood or chicken stock
• 1 large egg
• 1 teaspoon toasted sesame oil
• 6 to 8 scallions, trimmed to fit the width of your pan
• 1 cup mixed raw seafood (peeled shrimp, cleaned squid rings, and bay scallops work well), fresh or thawed and patted very dry
• 1 fresh red or green chili, thinly sliced, optional
• Neutral oil, for frying (vegetable, canola, or avocado oil)
• 2 tablespoons soy sauce
• 1 tablespoon rice vinegar
• 1 teaspoon sesame oil
• 1/2 teaspoon sesame seeds
• 1/2 teaspoon gochugaru (Korean red pepper flakes), optional
• 1 scallion, finely chopped, for the dipping sauce

Just flour, starch, scallions, and a handful of fresh seafood.

How to Make It

1. Whisk together the soy sauce, rice vinegar, sesame oil, sesame seeds, gochugaru, and chopped scallion for the dipping sauce, then set it aside.
2. Pat the shrimp, squid, and scallops completely dry with paper towels, since any leftover moisture will steam the batter instead of letting it crisp.
3. In a bowl, whisk together the flour, potato starch, and salt.
4. Pour in the ice-cold water and egg, whisking just until combined, leaving a few small lumps in the batter.
5. Stir in the sesame oil, then fold the dried seafood and sliced chili into the batter.
6. Heat a generous layer of oil in a nonstick skillet over medium-high heat.



A single layer of scallions across the pan becomes the base of the whole pancake.



7. Lay the scallions across the pan in a single overlapping layer, then pour the batter over them and spread it into a thin, even round.
8. Scatter the seafood and chili evenly over the top and press down gently with a spatula so everything sits flush against the batter.



Pressing the seafood flush against the batter keeps every piece from sliding off later.



9. Cook undisturbed until the edges turn deep golden and crisp, about 3 to 4 minutes.
10. Flip the pancake carefully in one motion, then press down with the spatula to crisp the second side, another 3 to 4 minutes.



That golden, cracked crust on the flip side is the whole reason for a hot, well-oiled pan.



11. Slide the pancake onto a cutting board, slice into wedges, and serve immediately with the dipping sauce.

The Korean Insider Tip

Keep your batter bowl sitting inside a larger bowl of ice water the entire time you're cooking, topping it up as the ice melts. A batter that stays cold from the first pancake to the last fries up noticeably crispier than one that's warmed to room temperature by the time you're halfway through, because warm batter develops more gluten and turns chewy instead of shattering.

Why This Recipe Works

• Potato starch cuts the gluten in the batter, which is what gives the edges that shattering, glass-like crunch instead of a soft, bready bite.
• Drying the seafood thoroughly before mixing keeps excess water from thinning the batter and turning the crust soggy.
• A generous layer of hot oil essentially shallow-fries the pancake rather than sautéing it, and that's the difference restaurants rely on.

Pro Tips

Seafood straight out of the package or freezer carries a surprising amount of water, and skipping the drying step is the single fastest way to end up with a soggy center no matter how hot your pan is.

A batter poured too thick takes longer to crisp all the way through, and the middle stays gummy long after the edges have browned. Spread it thin enough that you can just see the scallions through it.

Picture a restaurant kitchen for a second: the oil in that pan is deep enough to almost shallow-fry the pancake, not just coat the bottom. Home cooks tend to use a thin film of oil out of habit, and that alone accounts for most of the difference in crispiness.

Flipping too early, before the first side has fully set and browned, risks the pancake breaking apart mid-air. Wait until you can see the edges lift cleanly away from the pan before attempting the flip.

Plating Like a Local

Korean tables rarely plate pajeon on a white dish, it's almost always served straight on a dark wooden board or a stone platter that makes the golden crust and pink shrimp pop by contrast. Cut it into wedges rather than squares, fanned slightly so the crisp edge of each piece is visible instead of hidden underneath. Set the dipping sauce in a small bowl right at the center of the board, close enough that each wedge can be dipped without leaving the plate. A few extra sesame seeds scattered across the top just before serving catch the light in a way that makes the whole board look freshly made.

How to Serve and Variations

Haemul pajeon is best eaten within a few minutes of coming out of the pan, while the crust is still audibly crisp. For a version without shellfish, swap the seafood mix for extra scallions and a handful of thinly sliced kimchi, which turns it into kimchi jeon instead. If you want more heat, stir a spoonful of gochugaru directly into the batter rather than relying on the dipping sauce alone.

Leftover wedges lose their crunch quickly in the fridge, but a few minutes back in a dry, hot skillet brings most of the crispness back without needing extra oil.

What's the difference between pajeon and haemul pajeon?

Pajeon simply refers to any scallion pancake, while haemul pajeon specifically includes seafood mixed into the batter. Both use the same base recipe, so seafood is really the only variable that separates the two.

Can I use frozen seafood for this recipe?

Yes, frozen shrimp and squid work fine as long as they're fully thawed and patted very dry before going into the batter. Skipping that drying step is one of the most common reasons a homemade version turns out soggy instead of crisp.

Why does my pajeon turn out soft instead of crispy?

Soft pajeon usually comes down to one of three things: batter that's too warm, not enough oil in the pan, or seafood that wasn't dried thoroughly before mixing. Fixing all three at once is what gets you closest to the restaurant version.

Can I make this pancake without seafood?

Yes, simply leave out the shrimp, squid, and scallops and let the scallions carry the pancake on their own. The batter, technique, and dipping sauce all stay exactly the same either way.

Next time it's raining outside, this is the sound worth filling your kitchen with instead of the TV.
