Gochujang-Glazed Mackerel with Beet-Spinach Namul and Pumpkin Seeds
A Korean-style dinner: oily mackerel glazed in a bright gochujang lacquer, over two quick namul of sesame spinach and grated beet, showered with toasted pumpkin seeds.
Why it works
Mackerel ranks among the highest omega-3 oily fish there is, EPA and DHA both, and it also supplies zinc, a mineral central to testosterone synthesis and healthy reproductive function. Pumpkin seeds layer in even more zinc and magnesium. Spinach and beet are strong dietary-nitrate sources, feeding the same nitrate-nitrite-nitric-oxide pathway that drives vasodilation and blood flow, while garlic and sesame bring allicin and lignans that support vascular tone. This is a plate about hormonal and circulatory health. It is not a performance claim, and it was never trying to be one.
Grounded in the zinc-and-reproductive-function nutrient literature around shellfish and seeds, omega-3 cardiovascular evidence for oily fish, and the dietary-nitrate-to-nitric-oxide vasodilation pathway.
Ingredients
- 2 mackerel fillets (about 5 oz / 140 g each), pin bones removed
- 1 tablespoon gochujang
- 2 teaspoons soy sauce or tamari
- 1 teaspoon toasted sesame oil, plus 1 teaspoon for the namul
- 1 teaspoon rice vinegar
- 1 teaspoon honey
- 3 cloves garlic, minced (divided)
- 6 cups (about 5 oz / 140 g) fresh spinach
- 1 medium beet, peeled and coarsely grated
- 2 teaspoons toasted sesame seeds
- 3 tablespoons raw pumpkin seeds (pepitas)
- 2 scallions, thinly sliced
- 1 teaspoon neutral oil for the pan
- Steamed short-grain rice, to serve (optional)
Method
- Toast the pumpkin seeds in a dry skillet over medium heat, shaking often, 2 to 3 minutes until they pop and turn golden; tip out and reserve. In the same skillet, toast the grated beet with a splash of water and 1 clove minced garlic for 3 to 4 minutes just to soften, season with a pinch of salt, and set aside as the beet namul.
- Blanch the spinach in boiling water for 30 seconds, drain, and press out the liquid. Toss with 1 teaspoon sesame oil, 1 clove minced garlic, half the sesame seeds, and a pinch of salt to make the spinach namul.
- Whisk gochujang, soy sauce, 1 teaspoon sesame oil, rice vinegar, honey, and the remaining garlic into a glaze.
- Pat the mackerel dry and score the skin lightly. Heat the neutral oil in a skillet over medium-high and cook the fillets skin-side down 3 to 4 minutes until crisp, then flip and cook 1 to 2 minutes more.
- Lower the heat, brush the glaze over the fish, and let it bubble and lacquer for about 1 minute, spooning any extra over the top.
- Plate the spinach and beet namul side by side, lay a glazed mackerel fillet across them, and finish with toasted pumpkin seeds, the remaining sesame seeds, and sliced scallions. Serve with rice if desired.
