Meets Patient’s editorial guidelines

This elegant tuna carpaccio is a sophisticated choice for a light lunch or a refined dinner party starter. Using fresh, sushi-grade tuna, the fish is gently flattened into delicate rounds that melt in the mouth, beautifully contrasted by a vibrant balsamic vinaigrette. The peppery watercress and sharp shallots provide a balanced crunch that cuts through the richness of the fish, creating a refreshing and colourful plate that is as pleasing to look at as it is to eat.

As a diabetes-friendly dish, this recipe is naturally low in carbohydrates and rich in heart-healthy omega-3 fatty acids. The use of extra-virgin olive oil and fresh lemon juice ensures a bright flavour profile without the need for heavy sauces. It is a wonderfully healthy option for those seeking a protein-rich meal that feels indulgent yet remains light and nutritious.

Ingredients for Tuna Carpaccio with Watercress Salad and Balsamic Dressing

  • 2 tablespoons balsamic vinegar

  • 1/4 teaspoons Dijon mustard

  • 8 tablespoons extra-virgin olive oil, divided

  • Fine sea salt

  • 450g sushi-grade ahi tuna steaks, cut into 1-inch squares

  • 20ml fresh lemon juice

  • 2 teaspoons thinly sliced fresh chives

  • 1 teaspoon minced shallot

  • 2 cups (loosely packed) watercress sprigs (about 60g )

How to make Tuna Carpaccio with Watercress Salad and Balsamic Dressing

Combine vinegar and mustard in small bowl; whisk in 4 tablespoons olive oil. Season dressing to taste with sea salt and pepper. DO AHEAD: Can be made 1 day ahead. Cover; chill.

Place 1 sheet of plastic wrap on damp work surface (to prevent plastic from slipping). Arrange 1/4 of tuna squares 1 inch apart in circle on plastic. Cover with second sheet of plastic. Using flat side of mallet, gently pound tuna squares until they are very thin and form an 8- to 9-inch solid round. Place tuna round, still in plastic, on plate. Form 3 more rounds with remaining tuna. Refrigerate tuna carpaccio at least 30 minutes and up to 4 hours.

Peel 1 plastic sheet from each tuna carpaccio round; invert onto plates and peel off remaining plastic. Brush each with 1 tablespoon olive oil, then sprinkle with lemon juice, chives, shallot, sea salt, and pepper. Toss watercress and 2 tablespoons dressing in medium bowl; season to taste with sea salt and pepper. Mound watercress atop and serve.
