Best Seared Tuna With Sweet Balsamic Onions Recipes

SWEET AND SOUR SICILIAN TUNA

Steps:

• Heat olive oil in a heavy-bottomed skillet 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 skillet.
• Place the tuna steaks in the same skillet over medium-high heat and cook until golden brown, about 2 minutes per side. Remove the tuna steaks to a serving tray; keep warm.
• Stir the vinegar and sugar together in the same skillet 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.

SEARED TUNA WITH TOMATOES AND BASIL

Steps:

• In a 12-inch skillet, heat 1 1/2 tablespoons oil over medium-high heat. Season tuna generously with salt and pepper. Arrange half of tuna in skillet in a single layer to prevent crowding. Cook, turning once, until golden brown on top and bottom, about 1 1/2 minutes per side (3 minutes total). Tuna should be slightly pink inside. Transfer to a platter. Cover to keep warm. Add another 1 1/2 tablespoons oil, and repeat with second batch.
• Wipe out the bottom of the skillet. Add remaining 2 tablespoons oil and the onion. Cook over medium heat, stirring, until onion is golden brown and soft, 4 to 6 minutes. Add tomatoes and wine, and simmer, stirring often, until the tomatoes' skins just begin to wrinkle, about 2 minutes. Cook at a bare simmer until sauce thickens slightly, about 5 minutes more. Add basil to skillet, and cook, stirring, until wilted. Season with salt and pepper. Spoon hot sauce over tuna just before serving.

TUNA WITH SESAME CRUST AND BALSAMIC GLAZE

Steps:

• Mix vinegar and 2 tablespoons water with green onion and ginger in a bowl. Place tuna in mixture, and marinate about an hour.
• To cook, remove tuna from marinade; set marinade aside. Press sesame seeds into both sides of tuna. Heat nonstick pan to medium, and add oil. Quickly sear tuna on both sides, just a couple of minutes -- seeds brown quickly. Remove tuna from pan, pour in reserved marinade, and bring to a boil. Pour over tuna, and serve.
