Roast Tuna With Onions And Lemon Recipes

SLOW-ROASTED TUNA WITH TOMATOES, HERBS, AND SPICES

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.

TUNA WITH CAPERS, OLIVES AND LEMON

Steps:

• In a large bowl, mash garlic with the back of a spoon. Whisk in the lemon juice and 5 tablespoons of olive oil. Combine with the tuna, onion, olives, capers, herbs and salt to taste.
• Serve on buttered toast for sandwiches, or make into a dip: Pulse the tuna salad and butter in a food processor until it is creamy. With the motor of the processor running, slowly add the additional 4 tablespoons oil. Taste and add more salt or lemon juice if needed. Serve with cut vegetables (fennel and bell peppers are nice) and crackers.

ROAST TUNA WITH ONIONS AND LEMON

Steps:

• Preheat the oven to 450°.
• Put half the olive oil in a medium skillet or saucepan and turn the heat to medium; a minute later, add the onion and cook, stirring occasionally, until softened, about 5 minutes; add the garlic and chile, stirring occasionally, for about 1 minute.
• Turn off the heat and stir in the parsley, thyme, and bread crumbs, along with some salt and pepper to taste.
• Layer half the lemon slices in the bottom of a small roasting pan.
• Rub the fish with the remaining olive oil, sprinkle it with salt and pepper, and place it in the pan.
• Put the onion mixture and remaining lemon slices on top of the fish.
• Roast the fish until done, about 10 minutes for medium-rare (cut into it and take a look).
• Drizzle with the lemon juice and a little more olive oil and serve hot or at room temperature.

TUNA WITH ROASTED CIPOLLINE ONIONS

Steps:

• Bring a large pot of water to boil. Add the onions and cook for 2 minutes. Drain and cool. Peel the onions and cut off the root ends.
• Preheat the oven to 450 degrees F.
• Toss the onions, vinegar, 1 tablespoon oil, 1/2 teaspoon of salt and 1/4 teaspoon of pepper in a 13 by 9-inch baking dish. Roast in the oven until the onions are tender and golden, stirring occasionally, about 1 hour.
• Meanwhile, whisk the 1/3 cup oil, lemon juice, thyme, and remaining 1/2 teaspoon of salt and 1/4 teaspoon of pepper in another 13 by 9 by 2-inch baking dish. Place the tuna steaks in the marinade and turn to coat. Let stand for 5 minutes on each side.
• Oil the grill rack and prepare the barbecue for medium-high heat. Grill the steaks to desired doneness, about 3 minutes per side for medium. Cut the steaks in half. Transfer the steaks to a platter. Spoon the onion mixture around and serve.

ROASTED ONIONS WITH LEMON

Steps:

• Preheat the oven to 400 degrees F. Drizzle 2 tablespoons olive oil on a rimmed baking sheet. Scatter the rosemary leaves and thyme sprigs on the baking sheet. Season the onions with salt and pepper; arrange on top of the herbs, cut-side down.
• Remove 4 wide strips zest from the lemons using a vegetable peeler; set aside. Cut each lemon in half and remove any seeds; add to the baking sheet cut-side down. Roast until the onions are tender and the skins are slightly charred, about 1 hour.
• Meanwhile, make the vinaigrette: Combine the vegetable oil, vinegar, mustard and 1/2 teaspoon salt in a blender. With the motor running, gradually drizzle in the remaining 6 tablespoons olive oil and 2 tablespoons water until emulsified. Transfer to a small bowl; add the lemon zest and season with salt and pepper. Let steep at least 30 minutes; remove the lemon zest.
• Remove and discard the skins from the onions. Arrange the onions, lemons and herbs on a platter and drizzle with the vinaigrette just before serving. (The roasted onions and vinaigrette can be made up to 4 hours ahead. Serve at room temperature.)

SEARED TUNA WITH FENNEL-AND-LEMON SLAW

Steps:

• To make the slaw, whisk together in a large bowl the zest, lemon juice, olive oil, salt and black pepper. Add the fennel, toss and refrigerate for 1 hour. Carefully wrap the fennel fronds in plastic to keep them fresh, then refrigerate.
• When ready to serve, generously season the tuna on both sides with salt and pepper. Place a large, heavy skillet over medium-high heat. When the skillet is very hot, add the oil and immediately add the tuna. Cook, turning once, until the tuna is seared on the outside but still very pink at the center, about 5 to 10 minutes depending on its thickness.
• Slice the tuna into thin slices. Lay them over 4 serving plates, place a mound of slaw in the center of each plate, garnish with the chopped fennel fronds and serve.

TUNA STEAKS WITH LEMONY TOMATOES AND ONION

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.
