Best Oil Poached Tuna Recipes

OLIVE OIL-POACHED TUNA

Steps:

• Let tuna rest at room temperature for 10 to 15 minutes.
• Combine garlic, thyme, and red pepper flakes in a heavy skillet. Pour olive oil into skillet to reach a depth of 1 inch. Heat oil over medium heat until garlic and thyme begin to sizzle, 5 to 10 minutes.
• Place tuna gently in hot oil and reduce heat to low. Cook steaks in hot oil, spooning oil over the top of the steaks constantly, until fish is white and hot, 5 to 7 minutes. Remove from heat, transfer steaks to a baking dish, and pour hot oil and herbs over the fish. Cool fish and oil to room temperature.
• Wrap baking dish tightly in plastic wrap and refrigerate steaks for 24 hours. Remove fish from oil and sprinkle sea salt over the top.

TUNA POACHED IN OLIVE OIL

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.

OLIVE OIL POACHED TUNA MELTS

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.

OLIVE OIL POACHED TUNA INFUSED WITH THYME, LEMON, AND SHALLOTS

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.

OIL POACHED TUNA

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.

OIL-POACHED TUNA SALAD

Steps:

• Bring flageolet beans and 4 cups water to a boil in a large saucepan, reduce heat, and simmer until beans are tender, 50-60 minutes; season with salt. Let beans cool; drain. Transfer to a medium bowl. (Do not cook canned beans.)
• Cook green beans in another large saucepan of boiling salted water until crisp-tender, about 5 minutes. Drain and transfer to a colander set in a bowl of ice water. Let cool; drain and set aside. Wipe saucepan dry.
• Heat oil, rosemary, and garlic in same saucepan over medium-low heat until deep-fry thermometer registers 160°F. Season tuna with salt and pepper and cook in oil until opaque except for a bit of pink in the center, about 4 minutes per side. Using a slotted spatula, transfer tuna to a plate. Let poaching oil cool, then remove rosemary and garlic. Set aside 1/4 cup oil.
• Whisk anchovies, shallot, parsley, lemon juice, mustard, chopped dill, and reserved poaching oil in a small bowl; season with salt, pepper, and more lemon juice, if desired. Add some vinaigrette to bowl with flageolet beans and toss to coat.
• Break tuna into large pieces and arrange on a platter with flageolet and green beans, tomatoes, and olives. Top with a few dill sprigs and serve with remaining vinaigrette alongside.
• DO AHEAD: Tuna can be made 1 day ahead. Return fish to cooled oil, cover, and chill. Serve at room temperature.

OLIVE OIL POACHED ALBACORE TUNA, REMOULADE, AND CHEDDAR CHEESE SANDWICHES

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.

SPAGHETTI WITH OLIVE-OIL-POACHED TUNA IN TOMATO-FENNEL SAUCE

Steps:

• FOR THE TUNA
• Add the fennel seeds to a small sauté pan and bring to medium-high heat. (You need toasted fennel seeds for both the tuna and the sauce, so toss 2 tablespoons in the pan now and save a step later!) Toast the fennel seeds, shaking the pan frequently, until they are very aromatic and start to turn a brighter shade of green, 3 to 4 minutes. Remove from the heat and grind the seeds in a spice grinder or crush with a mortar and pestle.
• Season the tuna belly with salt, red pepper, and half the ground fennel seeds (you're saving the other half for the sauce).
• Preheat the oven to 200°F.
• Put the tuna in a medium ovenproof saucepan and cover with olive oil. Toss in the garlic, bay leaves, and thyme bundle. Cover and put in the oven; cook for 1 hour. Remove and let cool to room temperature. Use immediately or refrigerate in an airtight container.
• FOR THE SAUCE AND PASTA
• Coat a large wide saucepan with olive oil and add the onions and fennel; season with salt and red pepper and bring to medium heat. Cook the veggies until soft and aromatic, 8 to 10 minutes. Add the garlic and cook for another 2 to 3 minutes.
• Add the tomatoes, the reserved tablespoon of toasted fennel seeds, and 1 cup water to the pan and season with salt. Bring to a boil (BTB) and reduce to a simmer (RTS); simmer for 30 minutes.
• Bring a large pot of well-salted water to a boil. Add the pasta and cook for 1 minute less than the instructions on the package suggest. Taste it: It should be toothsome with just a little nugget of hard pasta still in the center-this is al dente.
• Remove the tuna from the olive oil, break it up, and add it to the sauce.
• Drain the pasta and add it to the sauce; stir vigorously to combine. Add a drizzle of big fat finishing oil and serve garnished with fennel fronds.
• YOU SAY TOMATO, I SAY SAN MARZANO
• San Marzano tomatoes are, as the name suggests, from San Marzano, Italy, outside of Naples. Sweet and delicious, these canned tomatoes are naturally very low in acid. Sometimes you'll notice people add a pinch of sugar to tomatoes when making sauce-this is not to sweeten the sauce so much as to offset the acid in the tomatoes. When you're using San Marzano tomatoes, this isn't necessary because they're naturally super-sweet and low in acid. However, for this same reason, they need a lot of salt to bring out their best flavor . . . accept it and move on.
• San Marzano tomatoes are perfect for sauce, and they work beautifully with my favorite piece of kitchen equipment: the food mill. It's super-old school but I love using a food mill to purée tomatoes because it lets the seeds slip through, leaving all the big-money stuff up top. Remember, when you put your tomatoes through a food mill, be sure to scrape the pulp off the bottom to get every last bit of tomato-y goodness! This is the stuff that will help thicken the sauce, so you don't want to leave it behind. Got it?

OIL-POACHED TUNA WITH ESCAROLE AND LIMA BEANS

Steps:

• Line heavy medium skillet with lemon slices. Sprinkle tuna with salt and pepper and place atop lemon. Add just enough olive oil to cover tuna. Poach tuna over medium-low heat until almost cooked through, about 3 minutes. Using slotted spoon, transfer tuna to plate. Discard lemon slices.
• Discard all but 1 tablespoon drippings from skillet. Add green onion and sauté over medium-high heat 1 minute. Add escarole, lima beans, and 3 tablespoons parsley to skillet. Sauté until escarole begins to wilt, about 1 minute. Sprinkle with vinegar. Season to taste with salt and pepper.
• Divide escarole-bean mixture between 2 plates and top with tuna slices. Sprinkle with remaining 1 tablespoon parsley and serve.
