About this dish
Godeungeo gamja jorim is a Korean home-cooked side dish where mackerel and potato chunks are braised together in a soy sauce and gochugaru seasoning.
Read more
The oily mackerel releases its fat into the braising liquid, building a rich, savory depth that plain soy sauce alone cannot achieve. Potato absorbs the spiced liquid as it simmers, cooking down to a fluffy, yielding texture that contrasts with the firmer fish. Onion and green onion contribute natural sweetness and aroma throughout the cooking process, and sugar rounds off the saltiness of the soy base to keep the seasoning balanced rather than sharp. Spooning the dark, glossy braising sauce generously over rice turns this side dish into a satisfying meal on its own. Using fresh mackerel rather than salted gives a softer, more delicate flesh that further enriches the cooking liquid.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Cut 300g mackerel into 3cm pieces, rinse under running water, and pat the outside and cavity dry.
- 2Control
Cut 250 g potato into thick 3 cm cubes so it will not collapse during braising.
Slice 100 g onion into broad strips, and cut 40 g green onion on a diagonal for the final simmer.
- 3Season
In a pot, combine 3 tbsp soy sauce, 1 tbsp Korean chili flakes, 1 tbsp minced garlic, 1 tbsp sugar, and 300 ml water.
Stir until the sugar dissolves so the sauce seasons evenly from the start.
- 4Control
Add the potato to the sauce first, cover, and simmer over medium heat for about 7 minutes.
When a chopstick goes halfway into a piece, place the mackerel on top without stirring hard.
- 5Control
Spread the onion and green onion over the mackerel, then spoon the hot sauce over the fish.
Reduce to low heat and braise 8 more minutes, basting instead of turning so the flesh stays intact.
- 6Finish
When the sauce is reduced and glossy, confirm the potatoes are tender through and the mackerel flesh is opaque.
Turn off the heat and serve once fully cooked.
