Best Seared Tuna With Oven Dried Tomatoes And Sweet And Sour 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.

SEARED TUNA WITH SWEET BALSAMIC ONIONS

Steps:

• Heat 1 tablespoon of oil in a large skillet over medium heat.
• Add the onion and sprinkle with sugar.
• Sautee about 10 minutes, until light brown and soft.
• Season with salt and pepper, and add the red wine vinegar. Cook 1-2 minutes, until most of the liquid evaporates.
• Add balsamic vinegar and cook for about 30 seconds.
• Transfer to a bowl.
• Wipe out pan and set over medium high heat, and add 1 tablespoon oil.
• Season the tuna with salt and pepper.
• When oil is hot, add the tuna steaks and sear for about 1 1/2 minutes on each side for rare.
• Top each tuna steak with 1/4 of the onion and garnish with chopped parsley.

TUNA STEAKS WITH GARLIC, TOMATOES, CAPERS, AND BASIL

Steps:

• Heat 3 tablespoons extra-virgin olive oil in heavy large skillet over medium heat. Add onions; sauté until tender, about 5 minutes. Add garlic; sauté until golden, about 3 minutes. Stir in tomatoes, basil, and capers. Simmer uncovered until mixture thickens, stirring occasionally, about 15 minutes.
• Meanwhile, heat remaining 3 tablespoons oil in another heavy large skillet over medium heat. Sprinkle fish with salt and pepper. Add fish to skillet and cook until light brown at edges but pink in center, about 3 minutes per side. Pour in tomato mixture. Simmer until fish is opaque in center, about 5 minutes longer. Serve fish immediately.

SEARED TUNA WITH OVEN-DRIED TOMATOES AND SWEET-AND-SOUR ONIONS

Steps:

• To make the tomatoes, preheat the oven to 280 degrees. Place the tomatoes on a baking sheet and sprinkle with the thyme, sugar, half of the garlic and salt and pepper. Bake for 3 1/2 hours.
• Meanwhile, to prepare the onions, combine the water, vinegar, sugar, salt and pepper in a medium-size saucepan and bring to a boil. Add the onion and cook for 5 minutes. Drain and let cool. Toss with the olive oil and set aside.
• When the tomatoes are cool enough to handle, coarsely chop them. Heat the olive oil in a medium-size skillet over medium heat. Add the tomatoes, tarragon and remaining garlic and cook for 2 minutes. Season with salt and pepper and set aside.
• To make the tuna, combine the rosemary, garlic, poppy seeds, cracked pepper and salt. Roll each piece of tuna in the mixture until well coated. Heat the oil in a large nonstick or cast-iron skillet over high heat. Sear on all sides until browned on the outside but medium rare in the center, about 6 to 8 minutes. Remove from pan and cut each piece across into 1/4-inch thick slices.
• Divide the onion mixture among 4 plates. Place the tomato mixture over the onions. Top with tuna slices, season with salt and serve immediately.
