Meaty bluefin tuna, is at its best when lightly seared and rare in the center. It’s crusted with furikake — a Japanese seaweed and sesame powder that’s typically sprinkled over warm rice or sushi. It adds a briny, ocean-y flavor and gives the tuna a delightful crust. Albacore or ahi (yellowfin) tuna would be delicious here as well, though the cook times may be a little shorter, depending on how thick the fish is. See protips for more information.
Ingredients
¼ cup unseasoned rice vinegar
1 tablespoon sugar
½ teaspoon salt, plus more to taste
1½ cups (10 ounces) Japanese or sushi rice, rinsed and drained
2 (5 to 7-ounce) bluefin tuna steaks Available in Our Premium Subscription Box
1 tablespoon soy sauce or tamari, plus more for serving
2 tablespoons furikake seasoning
2 tablespoons neutral, such as avocado or grapeseed
½ teaspoon toasted sesame oil
8 ounces baby bok choy, halved lengthwise
Togarashi for sprinkling, optional
Sriracha mayo for drizzling, optional
Directions
Prepare the Rice
In a small bowl, combine the vinegar, sugar, and ½ teaspoon salt, stirring to dissolve the sugar. In a medium saucepan over high heat, combine the rice with 2 cups water and bring to a boil. Reduce the heat to low, cover, and cook until the liquid is absorbed, about 15 minutes. Remove from the heat and set aside, covered, for 10 minutes. Spread the rice in a large shallow bowl and toss with the vinegar mixture. Cover with a kitchen cloth while you make the tuna and vegetables, tossing once or twice.
Sear the Tuna
Meanwhile, lightly season the tuna with salt. Brush with soy sauce and sprinkle with the furikake, pressing to adhere on all sides. Heat a medium cast-iron skillet over medium heat until hot. Add 1 tablespoon neutral oil and swirl to coat the pan. Add the tuna and sear until golden, 1 to 1 ½ minutes per side on the 4 long sides, keeping the short sides uncooked, for rare tuna. Transfer to a cutting board and let rest for 2 to 3 minutes.
Cook the Bok Choy
Wipe out the skillet and heat the remaining neutral oil and sesame oil over medium heat until shimmering. Add the bok choy, season with salt and cook until crisp-tender and lightly charred all over, 3 to 4 minutes. Transfer the bok choy to plates.
Finish and Serve
Using a very sharp knife, cut the tuna into ¼-inch thick slices. Divide the tuna and rice between the plates and serve with togarashi and sriracha mayo, if using.
