Black Sesame Seared Tuna (Printable)

Sushi-grade tuna crusted with black sesame seeds, seared rare, served with a zesty wasabi mayonnaise.

# What You Need:

→ Tuna

01 - 2 sushi-grade tuna steaks, 6 oz each, about 1 inch thick
02 - 1 tablespoon soy sauce
03 - 1 teaspoon sesame oil
04 - Salt and freshly ground black pepper to taste

→ Crust

05 - 1/2 cup black sesame seeds, toasted
06 - 1/4 cup white sesame seeds, toasted (optional)

→ Wasabi Mayo

07 - 1/4 cup mayonnaise
08 - 1 to 2 teaspoons wasabi paste
09 - 1 teaspoon rice vinegar
10 - 1 teaspoon lemon juice

→ Garnish

11 - Thinly sliced scallions
12 - Pickled ginger
13 - Lemon wedges

# How-To Steps:

01 - Pat tuna steaks dry with paper towels. Brush all sides with soy sauce and sesame oil. Season lightly with salt and pepper.
02 - Spread black and white sesame seeds on a shallow plate. Press each tuna steak into the seeds, coating all sides evenly and firmly.
03 - Heat a non-stick skillet or cast-iron pan over high heat. When hot, add a small amount of oil to coat the surface.
04 - Sear tuna steaks for 30 to 45 seconds per side, just until the sesame crust is golden and the interior remains rare. Remove from pan and rest briefly.
05 - In a small bowl, whisk together mayonnaise, wasabi paste, rice vinegar, and lemon juice until smooth. Adjust wasabi intensity to your preference.
06 - Slice tuna steaks against the grain into 1/2-inch thick slices.
07 - Arrange sliced tuna on plates, drizzle with wasabi mayo, and garnish with scallions, pickled ginger, and lemon wedges.

# Expert Suggestions:

01 -
  • It tastes like you spent hours in a restaurant kitchen, but you're plating it in under twenty minutes.
  • The contrast between the toasted black sesame crust and the tender rare center is genuinely addictive.
  • Wasabi mayo is your secret weapon—it transforms simple seared tuna into something unforgettable.
02 -
  • The thirty-second sear per side is not a suggestion—it's the difference between a silky rare center and rubbery disappointment, so use a timer if your instincts aren't sharp yet.
  • Sushi-grade tuna means the fish has been flash-frozen at minus-4 degrees Fahrenheit or colder to kill parasites; never use grocery store tuna that isn't specifically labeled sushi-grade for anything served rare.
03 -
  • Buy your tuna from a trusted fishmonger and ask specifically about sushi-grade status and how recently it was frozen—this conversation matters more than the price.
  • If you're nervous about searing, practice your pan temperature control with cheaper proteins first; the confidence you build will make this feel effortless.
