Seared Tuna Recipe

Learn the secret to making perfectly Seared Tuna with a Sesame Seed Crust in just 10 minutes flat. A healthy, delicious ahi tuna recipe that is flavorful and easy to make. Video. Plus 50+ Best Fish Recipes.

This Seared Tuna happened a lot in our catering days, so much so, I couldn’t bring myself to make it again for a long long time. But a good three years have passed now, and the other day I got a hankering for it, so I thought I’d share! It’s one of those recipes that may seem fancy, but honestly, it couldn’t be any simpler and the best part, it is, it is ridiculously fast!

Here we are pairing it with a cool and crunchy Asian Cucumber Salad and Seasoned Japanese Rice with Furikake, a light and refreshing summer meal.

Whenever you serve Ahi Tuna rare, make sure to use “sushi-grade” tuna. My favorite? Look for Saku Tuna.

Ingredients:

  • 10- 16 ounces ahi tuna, thawed (sushi-grade) see notes
  • 1 tablespoon soy sauce or GF liquid aminos
  • 2 tablespoons high heat oil for searing- peanut oil, wok oil, avocado
  • 3 tablespoons sesame seeds (black, or both black and white)
  • 1 teaspoon granulated garlic powder (or onion powder)
  • 1 teaspoon kosher salt
  • 1 teaspoon fresh cracked pepper
  • 1 teaspoon sugar
  • 1 teaspoon dried Italian seasoning (or dried thyme)

Instruction:

  1. Mix the Sesame Crust ingredients together in a small bowl.
  2. Pat dry the ahi tuna with paper towels.
  3. Place ahi tuna on a plate, coat all sides with soy sauce. This will help the sesame spice adhere to the tuna.
  4. Generously sprinkle all sides of the ahi tuna with the sesame mix, pressing it down into the flesh. Coat the sides. Read through the rest of the directions before starting because the next part goes very quickly.
  5. The goal here is to get a nice golden sear on all sides without cooking the ahi tuna all the way through. HOT PAN is key.
  6. Heat a cast-iron skillet over medium-high heat, until very very hot. Turn your hood fan on. Place tongs, metal spatula and splatter guard (or lid) near the stove. When the pan is hot a flick of water should sizzle loudly. Once the skillet is hot, turn the fan on high. Add the oil and coat the pan and let it get hot. Carefully lay the tuna in the pan, pressing it down into the skillet with a metal spatula. Sear 45-60 seconds- checking the underneath by lifting one corner to see if it is golden. When deeply golden, carefully flip. If not golden, turn the heat up. Sear the other side, 60-90 seconds until golden. Sear the long edges using tongs to hold it upright.
  7. Place on a cutting board, blot if you like, then using a very sharp knife, thinly slice, and serve.
  8. At this point, you could also refrigerate up to 3 days, and serve this later, chilled. Either way is good.

Ingredients:

  • 2 ahi tuna (yellowfin tuna) steaks ((about 4 oz. each, 1″ thick – see notes for thinner or thicker))
  • 2 tablespoons soy sauce
  • 1 tablespoon toasted sesame oil (see notes)
  • 1 tablespoon honey (see notes)
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper (to taste)
  • 1/4 teaspoon cayenne pepper ((optional))
  • 1 tablespoon canola oil (or olive oil)
  • green onions, toasted sesame seeds, and lime wedges (for serving (optional))

Instruction:

  1. Pat the ahi tuna steaks dry with a paper towel. Place on a plate or inside a plastic bag.
  2. Mix the soy sauce (2 tablespoons), toasted sesame oil (1 tablespoon), honey (1 tablespoon) kosher salt (1/2 teaspoon- OMIT if marinating for more than a couple hours, see notes), pepper (1/4 teaspoon), and cayenne pepper (1/4 teaspoon) until honey is fully dissolved. Pour over the ahi tuna steaks and turn over to coat completely. Optional: allow to marinate for at least 10 minutes, or up to overnight in the refrigerator. Also optional: Reserve a spoonful or two of the marinade before coating the fish for drizzling on top after you’ve cooked it.
  3. Heat a medium skillet (preferably non-stick or a well-seasoned cast iron skillet) on medium-high to high until very hot ( or medium medium-high for nonstick). I recommend giving cast iron 3-5 minutes to get hot and nonstick about 1 minute, depending on how thick it is.
  4. Add the canola oil (1 tablespoon) to the hot pan. Sear the tuna for 1 – 1½ minutes on each side for medium rare ( 2 -2½ minutes for medium-well to well, 30 seconds for very rare. See notes – this will vary based on thickness of the tuna steaks). (Note: different burners get hotter depending on your stove. Use your best judgement whether you use medium, medium-high, or high heat, as the marinade may burn if too high heat is used)
  5. Remove to a cutting board. Slice into 1/2 inch slices and serve garnished with green onions, toasted sesame seeds, and a squeeze of fresh lime juice, if desired.

Ingredients:

  • 2 TB regular strength soy sauce (or gluten-free tamari sauce)
  • 2 TB freshly squeezed lemon juice
  • 1 TB Asian toasted sesame oil (found in the Asian aisle)
  • 2 tsp garlic powder
  • 2 tsp granulated sugar
  • 1 tsp kosher salt
  • 1 tsp freshly cracked black pepper
  • 2 1/2 pounds fresh ahi tuna steaks (about 1 1/2-1 2/3 inches thick)
  • 3 TB canola or vegetable oil (for searing)
  • Optional: freshly chopped cilantro (green scallions, sesame seeds for garnish.)
  • Optional: Sriracha mayo for drizzling

Instruction:

  1. In a bowl, whisk together the first 7 ingredients to make a marinade. Towel dry tuna steaks and place in a glass or ceramic dish. Pour marinade over the fish, turning to coat well throughout. Cover tightly and chill several hours to overnight; turn fish over at least once in the middle of marinade time.
  2. Heat 3 TB oil in a large heavy skillet – use aluminum or stainless steel; not nonstick, as it won’t sear – until oil is smoking. Sear ahi steaks 1 1/2 minutes per side on high heat, taking care to flip carefully with a flat, steel spatula. (If your tuna is less than 1 1/2 inches thick, sear for only 1 minute per side.)
  3. Transfer seared ahi to a large cutting board and let rest/cool 10 minutes. Use a very sharp (serrated works well) knife to slice thinly across the grain.
  4. Serve chilled or at room temp. Sprinkle with sesame seeds and cilantro or green onions, if desired. Drizzle with Sriracha mayo if desired.

Seared Ahi Tuna Recipe

FAQ

What oil is best for searing tuna?

heat the canola oil until hot. Arrange the tuna in the pan without overcrowding it and cook for 15 seconds per side, making sure to sear edges as well. The sear should only penetrate 1/8-inch or less into the tuna steaks.

How does Gordon Ramsay sear tuna?

Chef Ramsay adds lime zest to the loin under the crust and again when plating to infuse fragrance throughout the dish. Searing happens quickly with tuna—only 30 seconds on each side over medium heat. If the pan gets too hot, add a touch of cold oil to keep the sesame seeds from burning.

How long should you sear tuna for?

Place the tuna steaks in the pan and sear for about 45 seconds without moving the steaks. Then, reduce the heat to medium and keep cooking for a minute and a half. Flip the tuna steaks over and let them cook for two more minutes if you want them rare, or three more minutes if you want them medium-rare.

Should tuna be cold before searing?

As noted above, keeping your fish chilled until the last moment is an important safety step, but beyond that, it’s also thermally advantageous. Cold tuna presents a greater barrier to heat transfer than does warm tuna, making overcooking less likely. To get a quality sear, you need high heat.
