Alfred Portale's Red Snapper With Potatoes and Onions

This elegant red snapper with potatoes and onions is a wonderful example of light, Mediterranean-style cooking. The dish combines delicate white fish with the robust flavours of kalamata olives, sun-ripened tomatoes and fragrant rosemary. By roasting the snapper on a bed of tender sliced potatoes, the fish remains moist while absorbing the aromatic juices from the wine and herb base. It is a vibrant, colourful plate that brings a touch of coastal sophistication to your dining table.

As a heart-healthy main course, this recipe relies on extra-virgin olive oil and fresh aromatics rather than heavy fats for its depth of flavour. The addition of tangy lemon and fresh parsley provides a bright finish that perfectly balances the savoury notes of the clam broth. It is an ideal choice for a nutritious midweek supper or a relaxed weekend lunch with friends, served alongside a crisp green salad or steamed seasonal greens.
