Grilled Mackerel with Clementine and Watercress Salad

30 Minutes | easy | Serves 2

Sharp and sweet fruit flavours work particularly well with mackerel as it’s a rich and oily fish. It’s also perfect for the barbecue – quick to cook and full of flavour.


  • 2 whole mackerel, cleaned and gutted
  • 2 cloves garlic, crushed or grated
  • 1 tablespoon runny honey
  • 4 tablespoons clementine juice
  • 2 tablespoons olive oil
  • 2 tablespoons lemon juice
  • 2 clementines, peeled and segments separated
  • ½ teaspoon Dijon mustard
  • 80g watercress
  • ½ small red onion peeled and finely sliced
  • Lemon wedges, to serve




Combine the garlic, 2 tablespoons clementine juice, the honey and 1 tablespoon oil.

Score each mackerel a few times on each side, without cutting through to the bone. Rub the marinade all over the mackerel. Season with salt and set aside for 15-20 minutes.​​​​​​​

Light two gas burners

Light two gas burners on the Jupiter Outback BBQ. Once it’s really good and hot, place the mackerel on the grill and cook for 3-5 minutes each side, or until just cooked through. The key with cooking fish is to wait for the fish to release itself from the grill before turning – this way you won’t leave the skin behind.​​​​​​​

Dress the salad
