Linguine with Grilled Tuna, Capers and Parsley

This vibrant linguine with grilled tuna, capers and parsley is a sophisticated take on a Mediterranean classic. By griddling the leeks and garlic alongside fresh yellowfin tuna, you develop a deep, smoky sweetness that perfectly balances the acidity of the lemon and the briny punch of the capers. It is a wonderful way to enjoy fresh fish, offering a lighter yet deeply satisfying alternative to traditional meat-based pasta sauces.

As a high-protein dish, this recipe is ideal for those seeking a nutritious, heart-healthy dinner that does not compromise on flavour. The combination of omega-3 rich tuna and fresh herbs makes it a brilliant choice for a post-workout meal or a fresh weekend lunch. Serve it simply with a crisp green salad for a complete homemade dining experience.

Ingredients for Linguine with Grilled Tuna, Capers and Parsley

  • 2 unpeeled garlic cloves

  • 1 large leek, halved and well-rinsed

  • 450g fresh tuna, such as yellowfin

  • 60ml extra-virgin olive oil, plus more for brushing

  • Kosher Salt

  • Freshly ground black pepper

  • 2 teaspoons finely chopped rosemary

  • 350g linguine

  • 2 cups parsley leaves, roughly chopped

  • 1 tablespoon capers, roughly chopped

  • Juice of 1 lemon

  • Crushed red pepper

Light a grill and preheat for at least 10 minutes or preheat a grill pan. Arrange the grill so half cooks over high heat and the other half can cook over moderately low heat. Meanwhile, soak 1 small bamboo skewer for 10 minutes.

Thread the garlic cloves onto skewer. Brush both sides of the leek and the tuna with olive oil and season with salt and pepper. Rub the tuna with the rosemary.

Oil the grill grates, then grill the leek cut side down and the tuna over high heat until grill marks form, 2 to 3 minutes. Flip the tuna and leek and move to the cooler part of the grill. Cook until the tuna is just slightly pink within and the leek is tender, about 8 minutes for the tuna and 15 minutes for the leek. Transfer to a work surface and let cool slightly.

Grill the garlic on the skewer over high heat, turning a few times, until blistered and slightly softened, about 2 minutes.

Remove the outer layer of the leek and discard; thinly slice the leek crosswise, discarding any pieces that are tough, and transfer to a large bowl. Peel the garlic and finely chop. Flake the tuna and add the garlic and tuna to the leek.

Meanwhile, cook the linguine until al dente; drain, reserving 1/2 cup of the cooking water. Add the hot pasta, parsley, capers, lemon juice and the 60ml olive oil to the bowl and toss. Add the cooking water, little by little, if necessary, to loosen the sauce. Season with salt, pepper and crushed red pepper, then serve immediately.
