Ingredients

3 tablespoons olive oil
1 large onion, cut into chunks
4 tuna steaks
1 cup red wine vinegar
1 cup sugar

Instructions

In a heavy skillet, heat olive oil over medium heat. Sauté the onion until softened and translucent, approximately 5 minutes. Lower the heat to medium-low and continue cooking, stirring occasionally, until the onion becomes very tender and develops a rich, dark brown color, about 15 to 20 minutes. Transfer the onion to a plate and set aside.
In the same skillet over medium-high heat, sear the tuna steaks until golden brown, around 2 minutes per side. Move the tuna steaks to a serving tray and keep warm.
In the skillet, combine vinegar and sugar, stirring until the sugar fully dissolves. Return the caramelized onion to the skillet and simmer until the sauce thickens slightly, about 5 minutes. Place tuna on the warm serving tray and spoon the onion and sauce over the top.
