Olive Oil Poached Tuna Recipes

Steps:

• Season tuna with salt. Stir 3 cups oil, the lemon zest, garlic, and thyme in a medium saucepan. Add tuna and more oil to cover tuna by 1/2 inch if needed. Set over medium-low heat. Cook, covered, until tuna is opaque, 30 to 40 minutes. Remove from heat; let cool completely. Tuna in oil can be refrigerated in an airtight container up to 3 days.
• To serve, remove tuna from cooking oil with tongs; transfer to paper towels to drain. Discard cooking oil. Flake into 2-inch pieces. Drizzle with oil; sprinkle with pepper. Serve with lemon and the tomato-olive salad. Garnish with thyme.

Steps:

• Season the tuna with salt and pepper and set aside. Combine the oil, thyme, lemon, garlic, red pepper and shallots in a large saucepot. Warm the oil over medium heat until it reaches 130 degrees F. Let the flavors steep for 10 minutes. Re-test the temperature, adjusting the heat, if necessary. Submerge the tuna in the olive oil poaching liquid and cook until it is firm and medium-rare, approximately 5 minutes.
• Remove the tuna from the oil. Slice each piece. Arrange the tuna medallions over stewed lentils accompanied by sauteed broccoli rabe. Serve seasoned with Fleur de Sel and moistened with the olive oil poaching liquid.
• Place the lentils in a pot. Add enough cold water to cover them by 2 inches. Season the water with salt then simmer the lentils over medium-high heat, stirring frequently, until the lentils are chewy, about 15 minutes. Drain the lentils and reserve.
• Heat the olive oil in a medium pot, over medium-low flame. Add the shallots, garlic, crushed red pepper, and rosemary. Cook stirring frequently until the shallots and garlic are golden, about 10 minutes. Add the tomato puree and cook until it begins to concentrate, about 7 minutes. Then add the lentils. Stew the lentils in the sauce over a very low flame until they are fully tender but still holding their shape, about 10 minutes. Serve warm.

Steps:

• Place the rosemary, bay leaves, and lemon slices along the bottom of a medium saucepan. Arrange the tuna on top, and pour the oil over to cover completely. Sprinkle with the salt and pepper. Cook over low heat for about 8 to 10 minutes, until the first bubble appears in the oil. (It should still be cool enough to be able to dip your finger in it.)
• Immediately remove the pan from the heat, flip each piece of fish over, and cover the pan with a lid. Allow the tuna to sit in the warm oil for about 5 to 10 minutes, until it's cooked all the way through. Remove the tuna and refrigerate. Strain the oil and reserve for the Remoulade, chilling it for at least 30 minutes, or until cooled to room temperature.
• Prepare Remoulade, as described in the recipe below.
• Place the tuna in a medium bowl and, using your fingers, flake it into large chunks. Add 3/4 cup of the Remoulade and mix to combine. Season with salt, pepper, and lemon juice, to taste. If you like, add the remaining Remoulade.
• Adjust the oven rack to the upper position, and preheat the boiler.
• Toast the bread, and the rub 1 side of each slice with the garlic clove. Place on a baking sheet, garlic side up.
• Pile the tuna unevenly over the bread. Crumble the cheese and scatter it unevenly over the center, leaving a 1-inch border of tuna around the edge. Heat under the broiler for about 30 seconds, until the cheese is melted. Squeeze a few drops of lemon juice over and sprinkle with chives.
• In the bowl of an electric mixer or in a medium stainless steel bowl, whisk the egg yolk, salt, and mustard by hand. Slowly drizzle in the oil, drop by drop, whisking constantly. As the mixture begins to thicken, add a teaspoon each of the lemon juice and water.
• Once you've added almost half of the oil, place the bowl in the mixer fitted with the whisk attachment, and mix on medium speed, or continue to whisk in the oil by hand. Pour the oil in a slow, steady trickle, scraping down the sides of the bowl as necessary. As the mixture thickens, add a little more of the lemon juice and water, and continue whisking until the remaining oil is completely incorporated and the sauce is thickened.
• Stir in the red onion, capers, cornichons, tarragon, and parsley. Season with lemon juice and salt, to taste.

Steps:

• Season tuna with salt and pepper. Place in a saucepan with garlic and enough oil to just cover. Bring to a gentle simmer, and cook over low heat until the fish is opaque, about 10 minutes. Do not let it boil. Remove from heat, and add lemon thyme and bay leaves. Let stand until room temperature. Use immediately, or transfer to a bowl, cover with plastic wrap, and refrigerate overnight. Let stand at room temperature for 1 hour before using.

Steps:

• Place the oil, thyme, rind of the lemon peeled into strips, bay leaves and crushed garlic in a pan and bring to a gentle boil over medium-high heat. Then remove the pan from the heat and add the trimmed fish. Let stand 20 minutes. Then remove the fish, reserving the poaching oil, cool and flake.
• In a bowl, combine the juice of the lemon with 1/3 cup reserved poaching oil. Whisk to combine and season with salt and pepper. To the dressing, add the celery, onions, hot and sweet peppers, olives, parsley, capers and tarragon. Season the fish with a little seafood seasoning and add to the salad. Combine with the tines of a large fork, cover and store.
• To serve, place the rack in the center of the oven and preheat the broiler.
• Shred the Cheddar or Gruyere cheese on the large side of a box grater.
• Pile the tuna salad on the bottom of the rolls. Top with the cheese. Place both the bottoms and tops under the broiler to toast and melt the cheese, 2 minutes. Serve hot.

Steps:

• Preheat the oven to 200 degrees F.
• In a baking dish just large enough to hold the tuna in 1 layer, place the tuna and sprinkle generously with the salt on both sides. Add the garlic, oregano and marjoram, then add enough olive oil to completely cover the tuna. Cover with aluminum foil and place in the oven. Cook until the tuna is thoroughly cooked and flakes easily, 3 to 4 hours.
• Carefully remove the baking dish from the oven and set on a rack to cool completely. Transfer the tuna, with enough oil to cover, to jars, and refrigerate until ready to use, up to 2 months in advance.
• Alternatively, tuna may be transferred to sterile mason jars and filled with olive oil within 1/2-inch of the top and processed in a hot water bath for 10 minutes, cooled, and stored at room temperature for up to 6 months. Jars may also be refrigerated for up to 6 months.

Steps:

• Preheat the oven to 300 degrees.
• Place tomatoes on a baking sheet and sprinkle with half the garlic; season with thyme, sugar, about 1/4 teaspoon salt and 1/8 teaspoon pepper.
• Bake until the tomtoes are shriveled, about 3 to 3 1/2 hours; let cool.
• Coarsely chop the tomatoes.
• Then heat the teaspoon of olive oil in a skillet over medium heat; add remaining garlic and cook until softenend, about 2 minutes.
• Stir in the tomatoes and tarragon, cook for 2 minutes more; taste and add salt and pepper as desired.
• Meanwhile, in a medium saucepan, over medium high heat, bring the water, vinegar, sugar, 1/2 teaspoon salt and 1/4 teaspoon pepper to a boil; add onion and cook until it just begins to soften, but is still crisp, about 5 minutes.
• Drain and let cool, then toss with olive oil and set aside.
• Heat about a quart of olive oil (for poaching the fish) to 140 degrees F (use an instant read thermometer), in a medium saucepan.
• Pat the fish dry with paper towels and season with salt and pepper.
• Slide fish into the oil and cook until it is pale grayish on the outside, but still pink inside, about 5 minutes.
• To serve, divide the pickled onions among 4 plates; top with tomato sauce, then tuna seasoned with additional salt and pepper, if desired.
