Ingredients You’ll Need
Here’s what you’ll want to gather for this sesame crusted tuna dish:
- Sushi-grade ahi tuna steaks (about 6 oz each)
- Soy sauce (or tamari for gluten-free)
- Sesame oil
- Fresh ginger, grated
- Garlic, minced
- Lime juice (or lemon juice)
- Black and white sesame seeds
- Neutral oil (like canola or avocado oil for searing)
- Salt & pepper
Optional but highly recommended: Wasabi mayo, spicy sriracha sauce, or a simple ponzu dipping sauce.
Step-by-Step Instructions
Step 1: Marinate the Tuna Steaks
Give the tuna a quick soak in soy sauce, sesame oil, lime juice, garlic, and ginger. Ten minutes is plenty—this isn’t a slow marinade. Think of it more like a flavor kickstart.
Step 2: Coat with Sesame Seeds
Mix white and black sesame seeds on a plate. Press each tuna steak firmly into the seeds, covering both sides. It’s a little like giving your tuna a jacket of crunch.
Step 3: Heat the Pan
You’ll need a skillet that can take the heat. Cast iron works beautifully here. Pour in a thin layer of oil and let it shimmer (but don’t let it smoke).
Step 4: Sear the Tuna
Lay the sesame-crusted tuna in the hot pan. Cook for about 45–60 seconds per side. That’s it. You want a golden crust on the outside and a rare to medium-rare center.
Tip: If you prefer it cooked further, give it an extra 30 seconds per side—but don’t go overboard or you’ll lose the buttery texture.
Step 5: Slice and Serve
Transfer tuna to a cutting board. Let it rest for a minute, then slice against the grain into thick strips. Serve with your favorite dipping sauce.
Serving Ideas
This seared ahi tuna recipe is incredibly versatile. Here are a few ways to enjoy it:
- On a salad: Toss greens with avocado, cucumber, and sesame dressing. Lay tuna slices on top.
- As an appetizer: Arrange slices with wasabi mayo and soy dipping sauce.
- In a bowl: Add rice, edamame, and pickled ginger for a sushi-inspired tuna bowl.
- With noodles: Pair with soba noodles tossed in sesame sauce.
I’ve even served this on toasted baguette slices for a quick crostini-style appetizer—it disappears fast.
Tips for Perfect Seared Tuna
- Buy the right fish: Look for sushi-grade tuna. It’s safe to eat rare and has the best flavor.
- Don’t over-marinate: Tuna is delicate. Too long in marinade, and it gets mushy.
- Hot pan, short cook: High heat creates that sesame crust without overcooking the inside.
- Slice sharp: Use your sharpest knife for clean, restaurant-style slices.
Flavor Variations
Want to change things up? Try these ideas:
- Spicy Sesame Crust: Mix chili flakes or togarashi into the sesame seeds.
- Herb Boost: Add fresh cilantro or parsley to the marinade.
- Citrus Twist: Swap lime for orange juice in the marinade.
- Grilled Tuna Steaks: Fire up the grill instead of pan-searing for a smoky flavor.
Dipping Sauce Ideas
The dipping sauce is where you can really play. A few favorites:
- Soy-Ginger Sauce: Soy sauce, rice vinegar, ginger, sesame oil.
- Spicy Mayo: Mayo + sriracha + lime juice.
- Ponzu: A citrusy Japanese sauce that pairs beautifully with fresh tuna recipes.
- Creamy Wasabi: Greek yogurt + wasabi paste + lemon juice.

Seared Tuna with Sesame Crust
Ingredients
Method
- Marinate the tuna: In a shallow dish, mix soy sauce, sesame oil, lime juice, garlic, and ginger. Add the tuna steaks and let them sit for about 10 minutes.
- Prepare the coating: Spread the sesame seeds on a plate. Remove the tuna from the marinade, pat dry, and season lightly with salt and pepper. Press each side of the tuna into the sesame seeds to coat evenly.
- Heat the pan: Place a cast iron or heavy skillet over medium-high heat. Add the neutral oil and let it heat until shimmering.
- Sear the tuna: Carefully place the tuna steaks in the pan. Cook for about 45–60 seconds on each side for rare centers, or up to 90 seconds if you prefer medium-rare.
- Rest and slice: Remove the tuna from the pan. Let it rest for 1–2 minutes, then slice against the grain into thick strips.
- Serve: Arrange the slices on a platter with lime wedges and your favorite dipping sauce.
Notes
- Use sushi-grade tuna only. It’s safe to eat rare and gives the best flavor.
- Don’t marinate too long — the lime juice can start “cooking” the tuna.
- A super hot pan is the trick to a crispy sesame crust.
- Serve immediately for the best texture and flavor.
