Mallorcan Baked Mackerel with Slow Tomato, Fennel and Orange

A coastal Mallorcan dinner of whole-fillet mackerel baked over a slow-cooked sofrito of tomato, fennel and orange zest, finished with toasted almonds and parsley. Mackerel is one of the most B12-dense fish in the Mediterranean — a single fillet delivers roughly 12 mcg, well past the daily target.

    Toast the sliced almonds in a dry small pan over medium heat for 2 minutes, shaking often, until golden. Set aside.

  6. 06

    Pat the mackerel dry, score the skin twice, season with salt and pepper, and brush with the remaining 1/2 tbsp olive oil.

  7. 07

    Lift the lid from the skillet, lay the mackerel skin-side up on the sofrito, and return to the oven uncovered for 8 minutes until the fish flakes.

  8. 08

    Squeeze lemon over the fish, scatter the toasted almonds and parsley, and bring the skillet to the table.
