Soy-Glazed Seared Mackerel with Shaved Cucumber Ribbons

This weeknight plate pairs crisp-skinned mackerel with a glossy, umami-rich soy-ginger glaze that comes together in the same pan while the fish rests. Mackerel is naturally rich in healthy fats and delivers a hefty dose of protein, making this a satisfying yet light dinner that won't sit heavy. Shaved cucumber ribbons add crunch, water content and a cooling contrast to the warm, savoury glaze, while a scattering of sesame and scallion brings freshness without any cream or heavy sauces. Everything here is built for a quick, low-effort weeknight cook: one pan, one bowl, about fifteen minutes start to finish. The portion is deliberately modest and protein-forward rather than carb-heavy, so it's easy to finish and genuinely satisfying without feeling overly full. Keep the glaze light-handed — just enough to coat the fish in a thin, glossy layer — so the dish stays bright and savoury rather than sweet or greasy.

Ingredients

• 2 filletsmackerel fillets, about 120g each, skin on, pin-boned
• 1 largecucumber, shaved into ribbons with a peeler
• 3 tbspsoy sauce, low sodium if possible
• 1 tbspfresh ginger, grated or minced
• 1 clovegarlic, minced
• 1 tbsprice vinegar
• 1 tspMonk fruit or allulose sweetener, optional, to round out the glaze without sugar
• 1 tspAvocado oil, for searing
• 1 tspsesame seeds, for garnish
• 1 stalkScallion, thinly sliced, for garnish
• salt, a small pinch, to season cucumber

Method

1. Using a vegetable peeler, shave the cucumber lengthwise into long ribbons. Place in a mixing bowl, sprinkle with a small pinch of salt and toss gently; set aside to crisp while you cook the fish.
2. In a small bowl, whisk together the soy sauce, grated ginger, minced garlic, rice vinegar and sweetener to make the glaze.
3. Pat the mackerel fillets completely dry with paper towel, especially the skin, to help it crisp.
4. Heat the avocado oil in a non-stick skillet over medium-high heat until shimmering. Lay the mackerel in skin-side down and press gently with tongs for a few seconds to prevent curling.
5. Sear undisturbed until the skin is deeply golden and crisp. 3:00
6. Flip the fillets and cook the flesh side briefly until just cooked through. 1:30
7. Pour the soy-ginger mixture into the pan around the fish. Let it bubble and reduce, spooning the glaze over the fillets, until thickened and glossy. 1:30
8. Drain any excess liquid from the cucumber ribbons and divide them between two plates. Top each with a glazed mackerel fillet and spoon over any remaining glaze from the pan.
9. Scatter with sesame seeds and sliced scallion, then serve immediately.
