Korean Pan-Fried Spicy Mackerel, known as Gogalbi, is a flavorful Korean seafood dish associated with Busan.
It combines crisp, golden mackerel fillets with a glossy spicy glaze that delivers a balanced mix of heat, sweetness, tanginess, and savory depth.
The dish comes together without complicated cooking, making it a practical choice when you want a satisfying Korean-inspired main course.
Salted mackerel provides the rich, naturally savory foundation, while a light coating of cornstarch helps the fillets develop a crisp exterior as they are pan-fried.
The glaze brings together Korean chili paste, Korean chili flakes, soy sauce, sweet rice wine, sugar, garlic, ginger paste, Korean plum extract, sesame oil, sesame seeds, and black pepper.
Once the sauce is spread over the crispy fish, the fillets are gently simmered so the glaze settles onto the surface and creates a flavorful coating.
The optional bed of sliced onions adds another pleasant element to the presentation and texture.
Soaking the onions briefly in ice water softens their sharpness while keeping them crisp, making them a refreshing contrast to the rich mackerel and spicy glaze.
Served warm over the onions alongside rice, Gogalbi makes a hearty main dish that brings together contrasting textures and bold Korean flavors in every bite.
The crispy fish, sticky chili glaze, and fresh crunch of onion make this an especially appealing way to enjoy mackerel.

Ingredients
Equipment
Method
- Prepare the Rice Water: Place the rice in a bowl and add 3–4 cups of water, or enough water to soak the fish, then swirl the rice briskly until the water becomes milky from the released starch.
- Thaw the Mackerel: Remove the frozen salted mackerel fillets from their package and soak them in the prepared rice water for 10 minutes to thaw.
- Mix the Chili Glaze: While the mackerel thaws, combine the gochujang, gochugaru, soy sauce, sweet rice wine, sugar, minced garlic, ginger paste, Korean plum extract, sesame oil, sesame seeds, and black pepper in a small bowl.
- Prepare the Fish: Remove the mackerel fillets from the rice water and pat them dry thoroughly with paper towels, then lightly coat both sides with cornstarch.
- Heat the Skillet: Add the cooking oil to a nonstick skillet and heat it over medium heat.
- Pan-Fry the First Side: Place the mackerel in the skillet with the skin side facing up first, then cook for 3–4 minutes until the underside develops a golden, crisp surface.
- Flip the Fillets: Carefully turn the mackerel over and sear the second side for another 3–4 minutes, cooking until both sides are golden and crispy.
- Apply the Glaze: Reduce the heat to low, then spread the spicy chili sauce over the tops of the mackerel fillets, using about 1 1/2 tablespoons of sauce per fillet.
- Set the Glaze: Cover the skillet with a lid and simmer the glazed mackerel over low heat for 4–5 minutes, allowing the sauce to set onto the fillets like a glaze.
- Prepare the Onion Bed: For the optional garnish, soak the sliced yellow and red onions in cold ice water for a few minutes to mellow their sharpness and give them a crisp texture, then drain well and arrange them on a serving platter.
- Serve the Mackerel: Transfer the glazed mackerel fillets onto the prepared bed of onions and serve warm with rice.
Notes
- Use the rice water to soak the frozen mackerel for 10 minutes before cooking, as directed in the original recipe.
- Pat the mackerel dry after soaking so the cornstarch can lightly coat both sides of the fillets.
- Coat the fish lightly with cornstarch rather than applying a thick layer.
- Begin pan-frying with the skin side facing up, then turn the fillets once the first side becomes golden and crisp.
- After both sides are crisp, reduce the heat to low before adding the spicy chili glaze.
- Use about 1 1/2 tablespoons of sauce per fillet so the glaze coats the fish without overwhelming it.
- Keep the skillet covered during the final 4–5 minutes so the glaze can set onto the mackerel.
- The sliced onion garnish is optional, but soaking it briefly in ice water helps mellow its sharpness while keeping it crisp.
Chef’s Secret
The key to getting the best texture from this Gogalbi is to make sure the mackerel is properly dried before the cornstarch coating is applied.
After removing the fillets from the rice water, gently pat both sides with paper towels until the surface is dry.
A light, even coating of cornstarch helps the fish develop the golden, crisp exterior that contrasts with the soft, rich mackerel inside.
Once both sides have been pan-fried, lower the heat before applying the chili sauce.
This gives the glaze time to settle onto the fish without rushing the final cooking stage.
Covering the skillet for the last 4–5 minutes allows the sauce to cling to the fillets and develop the glossy glazed finish that makes this dish distinctive.
Serving Suggestions
Serve the glazed mackerel warm over the optional bed of crisp yellow and red onions, alongside freshly prepared rice.
The rice provides a simple base for the bold chili glaze and rich mackerel.
For the garnish, keep the sliced onions fresh and crisp, and add sesame seeds if desired since they are already part of the glaze.
Arrange the fillets carefully on a platter so the golden crust and glossy sauce remain visible.
Conclusion
Korean Pan-Fried Spicy Mackerel brings together crisp fish, a glossy chili glaze, and contrasting fresh onion for a satisfying Korean-style main course.
The combination of gochujang, gochugaru, garlic, ginger, sesame oil, and Korean plum extract gives the mackerel its distinctive sweet, spicy, tangy, and savory character.
Served warm with rice, this Gogalbi makes a flavorful meal while keeping the cooking process straightforward.
