You'll be surprised how delicious this very simple sweet and sour sauce tastes with fresh tuna steaks.


Serves: 4 

  • 3 tablespoons olive oil
  • 1 large onion, cut into chunks
  • 4 tuna steaks
  • 1 cup (250ml) red wine vinegar
  • 1 cup (200g) sugar

Preparation:5min  ›  Cook:35min  ›  Ready in:40min 

  1. Heat olive oil in a heavy-bottomed frypan over medium heat. Stir in the onion; cook and stir until the onion has softened and turned translucent, about 5 minutes. Reduce heat to medium-low and continue to cook and stir until the onion is very tender and dark brown, 15 to 20 minutes more. Remove the onion from the frypan.
  2. Place the tuna steaks in the same frypan over medium-high heat and cook until golden brown, about 2 minutes per side. Remove the tuna steaks to a serving tray; keep warm.
  3. Stir the vinegar and sugar together in the same frypan until sugar is dissolved. Return the onions to the pan and simmer until the liquid reduces and is slightly thickened, about 5 minutes. Return the tuna to the pan and cook for 3 to 5 minutes. Place the tuna on the warm serving tray and top with the onion and sweet and sour mixture.
