Grilled mackerel with couscous, beans, tomatoes & dill

This meal can be made in a flash, or the tomatoes can be flavoured ahead, to really get the flavours mingling. Either way, it’s simple and delicious – plus it can be eaten warm or at room temperature, so it is super versatile.

  • 2 tsp Cooks’ Ingredients Rose Harissa Paste
  • 1 unwaxed lemon, finely grated zest and juice
  • 1 clove/s garlic, crushed
  • 1 tbsp Essential Olive Oil
  • 1 tsp Essential Pure Clear Honey
  • 250g mixed baby tomatoes, quartered
  • 20g pack dill, leaves chopped
  • 150g essential couscous
  • 240g Essential Round Beans, trimmed and cut into thirds
  • 4 mackerel fillets from the fish counter (or use frozen, defrosted)


  1. Put the harissa paste, lemon zest and juice, garlic, olive oil and honey into a large bowl. Add the tomatoes, dill and a pinch of salt, then toss well to combine. Set aside at room temperature for the flavours to mingle.

  2. Prepare the couscous according to pack instructions. Boil the beans for 3 minutes, or until just tender, then drain and stir through the tomato mixture. Preheat the grill to high.

  3. When the couscous is ready, fluff up with a fork, tip it into the dressed tomatoes and beans and stir well to combine. Lightly season the mackerel and place, skin-side up, on a foil-lined baking sheet. Grill for 4-5 minutes, until the skin is lightly charred and the fish is opaque and cooked through. Serve with the couscous.

Cook’s tip

If you decide to prep the tomatoes ahead, make sure they come back to room temperature before adding the beans and couscous. A little zaatar sprinkled over the fish before grilling adds great depth of flavour. A pinch of ground cumin will add a similar spicy note.
