Tuna Or Swordfish Steaks With Roasted Tomato And Onion Recipes

Steps:

• Preheat oven to 200°F. Using knife, make 9 slits in sides of tuna. Fill each with 1 clove, 1 coriander seed, and 1 garlic sliver; sprinkle tuna with salt and pepper. Heat oil in ovenproof pot over medium heat. Add onion and sauté 8 minutes; push to side of pot. Add tuna and sauté until brown on all sides, about 12 minutes. Scatter tomatoes, oregano, and remaining garlic slivers around tuna. Sprinkle with salt and pepper. Pour vinegar over fish.
• Bake tuna uncovered until thermometer inserted into center registers 145°F for medium-rare, about 12 minutes. Transfer tuna to platter. Spoon tomato sauce over. Cool to room temperature. Slice tuna thinly and serve.

Steps:

• Put olive oil in a 10- or 12-inch skillet, and turn heat to medium. Add onions, a good pinch of salt, pepper and thyme or bay leaf. Cook, stirring, until mixture starts to sizzle, a minute or two. Adjust heat so that you need to stir at most every 5 minutes to keep onions from browning as they soften. Cook at least 30 minutes.
• Meanwhile, cut tomatoes in half and shake out seeds, then cut into 1/2-inch dice. Heat a grill until moderately hot.
• When onions are very soft, almost a shapeless mass, season fish and grill, turning once, for a total of about 6 minutes for tuna, 8 to 10 minutes for swordfish; check for doneness by making a small cut in the center to peek inside. While fish is grilling, stir olives and tomatoes into onions, and raise heat; cook, stirring occasionally, until tomatoes liquefy and mixture becomes juicy. Taste, and adjust seasoning. Serve fish on a bed of onion confit, whole fish cut into serving portions.

Steps:

• Put the olive oil in a 10- or 12-inch skillet over medium heat. Add the onions, a healthy pinch of salt, some pepper, and the thyme. Cook, stirring occasionally, until the mixture starts to sizzle, a minute or two. Adjust the heat so that you have to stir only every 5 minutes at most to keep the onions from browning. They will become progressively softer; do not allow them to brown. Figure at least 30 minutes total for the onions to cook.
• Core the tomatoes, then cut them in half horizontally. Squeeze and shake out the seeds, then cut the tomatoes into 1/2-inch dice. Preheat a grill to moderately hot.
• When the onions are very soft, almost a shapeless mass, season the fish and grill it, turning once, for a total of about 6 minutes for tuna, 8 to 10 minutes for swordfish; check for doneness by making a small cut in the center of the fish and peeking inside. (Tuna can be quite rare; swordfish is best cooked to medium, when its interior is still slightly pearly rather than completely opaque.) While the fish is grilling, stir the olives and tomatoes into the onions and raise the heat a bit; cook, stirring occasionally, until the tomatoes liquefy and the mixture becomes juicy. Taste and adjust the seasoning. Serve the fish on a bed of the onion confit.
• Variations
• Chicken with Onion Confit: Serve the onions with grilled skinless, boneless chicken breasts.
• Omit the thyme and use a bay leaf instead, or finish the dish with a handful of chopped fresh basil, chervil, or parsley.
• Cook some finely chopped aromatic vegetables, like carrots, celery or fennel, and garlic, along with the onions.

Steps:

• First make the salsa. Preheat the broiler. While it is heating, prepare the corn. Holding each ear upright, cut off the kernels with a sharp knife. Heat a large heavy-based skillet or frying pan without any fat over high heat until almost smoking. Add the kernels and dry-roast until tender, smoky and dark, tossing continuously as they tend to stick, 4 to 5 minutes. Cook the peppers under the broiler, turning them until the skin chars and bursts, 7 to 10 minutes. Put them in a plastic bag and leave to sweat and cool so the skins loosen. Peel the peppers, discarding cores and seeds. Dice the flesh.
• Heat 1 tablespoon of the olive oil in a large frying pan. Add the onion and saute until soft but not brown, 3 to 4 minutes. Take the pan from the heat and stir in the roasted corn, chopped tomatoes, sun-dried tomatoes, diced peppers, vinegar and remaining oil. Heat, stirring, until hot. Take from the heat and keep warm.
• Rinse fish steaks and pat dry with paper towels. Brush with half the oil, season with salt and pepper and set on oiled grill pan or grill. Broil 3 to 4 minutes. Turn steaks over, brush with the remaining oil and grill until done to taste, 2 to 3 minutes longer.
• Meanwhile, stir the cilantro and lime juice into the salsa, taste and adjust seasoning. Make a bed of salsa on 4 warmed plates and place a tuna steak on top of each. Serve at once.

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.

Steps:

• In a large skillet, heat 1 tablespoon oil over medium-high. Season tuna with salt and pepper. Cook, without turning, until golden brown on one side, 3 to 5 minutes. Turn over, and continue to cook until medium-rare, 1 to 2 minutes more. Transfer tuna to a plate, and set aside.
• In a medium bowl, toss together tomatoes, onion, lemon juice, and remaining tablespoon oil; season salad with salt and pepper.
• Serve tuna on top of tomato-onion salad, with lemon wedges alongside, if desired.

Steps:

• Heat oven to 220C/fan 200C/gas 7 and put in a roasting tin to heat up. Put the tuna in a shallow dish with half the oil, two-thirds of the garlic and leaves from 1 sprig of thyme. Leave to marinate while you cook the veg.
• Put the potatoes, peppers, onion and chilli into the roasting tin with the remaining oil, toss to coat, then roast for 20 mins. The potatoes should be tender or very nearly there. If not, give them another 5 mins (the cooking time can depend on the variety of potato). Add the remaining garlic and thyme to the pan, let them sizzle, stir in the tomatoes, then cook for 5 mins more until the sauce has reduced a little. Season to taste.
• With a few mins to go, heat a griddle or frying pan, wipe most of the garlic marinade off the fish with kitchen paper, season, then sear for 1 min each side for medium or longer if you prefer. Serve on top of the veg.
