How To Make Sesame Ginger Seared Tuna

I designed this recipe to be super-simple, so you can get delicious ahi tuna like at your favorite restaurant, at home!

Sesame Ginger Seared Tuna Ingredients

To make this recipe, we will need the following ingredients:

• 2 tablespoons soy sauce: Brings deep umami flavor and saltiness that pairs well with the richness of the tuna.
• 1 tablespoon sesame oil: Adds a toasty, nutty aroma and authentic Asian flavor. A little goes a long way.
• 1 tablespoon fresh ginger, grated: Provides bright, peppery heat and depth. Fresh ginger cuts through the richness of the fish and sesame.
• 1 garlic clove, minced: Gives a savory, aromatic kick and complements the ginger.
• 1 tablespoon rice vinegar: Adds tangy acidity that balances the salty soy and rich sesame oil, helping tenderize the tuna slightly.
• 1 teaspoon honey or brown sugar: Balances acidity and salt with a hint of sweetness. Also helps the exterior caramelize slightly when seared.
• 1 teaspoon lime or lemon juice (optional): Adds a pop of brightness and citrusy zing to enhance the fresh flavor of the tuna.

Sesame Ginger Seared Tuna Method

Once you’ve gathered your ingredients, we will use the following process:

Marinate Tuna

In a shallow dish or zip-top bag, whisk together the soy sauce, sesame oil, ginger, garlic, vinegar, honey, and citrus juice.

Cover in Sesame Seeds

Remove tuna from the marinade and pat dry.
Press sesame seeds onto the top, bottom, and sides of each steak to coat well.
Sprinkle lightly with salt and pepper.

Sear

Heat a non-stick or cast iron skillet over medium-high heat.
Add oil and heat until shimmering.
Place tuna steaks in the pan and sear for 45 seconds to 1 minute per side (for rare). For medium, cook 1½–2 minutes per side.
Remove immediately and let rest for 1–2 minutes.

Slice & Serve

Slice tuna against the grain into thin strips.
Serve with:
Steamed rice or rice noodles
Pickled vegetables
Extra soy sauce or ponzu for dipping
Garnish with green onions or a drizzle of sriracha mayo

How to Get Perfect Seared sesame Encrusted Tuna

Use sushi-grade ahi or yellowfin tuna: High-quality tuna is essential since it will be mostly raw inside. Look for steaks that are bright red, fresh-smelling, and about 1–1½ inches thick.

Keep it cold until ready to cook: Cold tuna helps prevent overcooking the interior during the fast sear.

Pat the tuna dry: Moisture prevents browning. Blot with paper towels to get a dry surface for a better sear.

Season simply but well: Sprinkle with salt and pepper or roll in a mix of sesame seeds and spices (e.g., garlic powder, chili flakes) for extra flavor and crunch.

Optional: Marinate briefly: A short marinade (15–30 mins) with soy, ginger, sesame oil, and garlic adds flavor without overpowering. Pat dry before searing.

Use a heavy pan (cast iron or stainless steel): These pans hold high heat well and create the best crust.

Get your pan very hot: Heat over medium-high to high heat until the oil shimmers but doesn’t smoke.

Use a high-smoke point oil: Avocado, canola, or grapeseed oil are ideal. Avoid butter or olive oil for searing.

Sear for 45 seconds to 1 minute per side: For rare center (ideal), sear only until a golden crust forms, then flip. Do not cook past 1½ minutes per side unless you want it medium.

Let rest for 2–3 minutes: Allows juices to redistribute and finishes carryover cooking slightly.

Slice against the grain: Use a sharp knife to slice into thin strips or thick medallions for the best texture.
