How to Make Seared Ahi Tuna
Prepare the Wasabi Yogurt: In a small bowl, whisk together ¼ cup full-fat Greek yogurt, ½ to 1 tsp wasabi paste (according to your heat preference), 1 tsp fresh lime juice, and a pinch of kosher salt until the mixture is smooth and creamy. Cover the bowl and refrigerate it until you’re ready to serve.
Make the Ginger-Soy Sauce: In another bowl, combine 3 tbsps low sodium soy sauce, 1 tbsp rice vinegar, 1 tbsp honey or maple syrup, 1 tsp freshly grated ginger, and 1 tsp toasted sesame oil. Whisk until all the ingredients are blended and set aside. Allow the ginger to infuse during the rest of the preparation.
Prepare the Cucumber Salad: Using a Y-peeler, shave the English cucumber lengthwise into long ribbons, stopping just before hitting the seedy core. Place these ribbons into a bowl and sprinkle them lightly with kosher salt. Let them sit for 5 minutes, allowing excess moisture to drain. Afterward, gently squeeze out any remaining water, then toss with 1 tbsp rice vinegar, 1 tsp honey or granulated sugar, and 1 tsp toasted sesame oil. Refrigerate until it’s time to plate.
Prepare the Ahi Tuna Steak: Pat the ahi tuna steak dry thoroughly with paper towels. Lightly season all sides with kosher salt for optimal flavor.
Sear the Ahi Tuna: Preheat a cast iron skillet over high heat for 3 to 5 minutes until it’s very hot. Add 2 tsps avocado oil or canola oil and swirl it around to coat the surface. Carefully place the tuna in the skillet and sear it without moving for 45 to 60 seconds on one side to achieve a rare center. For a thicker cut, you can sear up to 75 seconds per side. Don’t forget to sear the edges briefly (about 10 seconds) for a clean finish without cooking through.
Rest and Slice the Tuna: Transfer the seared tuna to a cutting board and let it rest for about 2 minutes. Slice the steak against the grain into ¼- to ½-inch slices, wiping the knife clean between each cut to achieve neat edges.
Plate the Dish: For an attractive presentation, swipe a generous layer of the wasabi Greek yogurt on each plate. Artfully arrange thinly sliced watermelon radish over the yogurt before placing the tuna slices slightly overlapping, showcasing the rare pink inside. Add a small mound of the cucumber ribbon salad on the side. Finish it all off with a light drizzle of the ginger-soy sauce and sprinkle a mix of black and white sesame seeds on top. Serve immediately and enjoy every bite!
Storing & Reheating
For the best quality, store any leftover Seared Ahi Tuna in an airtight container in the refrigerator for up to 2 days. The texture may change slightly, but it can be enjoyed cold, paired with the leftover sauces, or lightly warmed in a skillet over low heat just until heated through—aim for 5 to 10 seconds to keep it tender. Avoid freezing the tuna as it can compromise the texture once thawed.
Chef’s Helpful Tips
- Make sure your skillet is hot enough before adding the tuna; this ensures a beautiful sear without overcooking.
- Always choose sushi-grade fish for searing; this guarantees safety and taste.
- If you have it, let the tuna sit at room temperature for about 10 minutes before cooking for more even cooking.
- Adjust the wasabi in the yogurt to match your spice preference; remember, it adds a delicious kick!
- Use a sharp knife designated for fish to slice through the tuna easily and cleanly.
- Feel free to get creative with your salads—substituting radishes for others or adding avocado can elevate your dish!
Seared Ahi Tuna is such a captivating dish that strikes the perfect balance between elegance and simplicity. Each component contributes to a delightful experience that your taste buds will cherish. So go ahead, let yourself get creative with the sides or sauces, and maybe even invite a friend over to share in the feast.
