Ingredients

• 4 ahi tuna steaks about 6 oz each (170 g each)
• 1/2 cup sesame seeds mixed white and black
• 3 tablespoons low sodium soy sauce
• 2 tablespoons toasted sesame oil
• 1 tablespoon honey or agave
• 1 teaspoon grated fresh ginger
• 1 clove garlic minced
• 1 tablespoon lime juice
• 1 tablespoon neutral oil for searing, such as canola or grapeseed
• 1 ripe avocado sliced
• 1/4 cup microgreens or baby greens for garnish
• 1 tablespoon toasted sesame seeds reserved for finishing
• Lime wedges for serving, optional

Instructions

1. Pat the tuna steaks dry with paper towels, this helps the sesame seeds stick and gives a better sear.
2. In a shallow bowl mix soy sauce, sesame oil, honey, grated ginger, minced garlic, and lime juice to make a quick marinade.
3. Pour half of the marinade into another shallow dish for dipping and place the tuna in the remaining marinade for 5 to 10 minutes while you prepare the seeds and sides. Do not marinate longer than 20 minutes or the texture will change.
4. Spread the sesame seeds on a plate and press each marinated tuna steak into the seeds to coat all sides, pressing gently so the seeds adhere.
5. Heat the neutral oil in a heavy skillet over medium-high heat until shimmering but not smoking. Sear the tuna 1 to 1 1/2 minutes per side for rare, 2 minutes per side for medium rare, adjusting time for thickness. You want a dark crust and a pink center.
6. Remove the tuna to a cutting board and let it rest 1 to 2 minutes, then slice thinly across the grain.
7. Arrange slices on a warm plate, add avocado slices and a small ramekin of the reserved marinade for dipping, sprinkle microgreens and reserved toasted sesame seeds over the tuna, serve with lime wedges.

Recipe Variations

• Spicy Ponzu Ahi: Swap the soy dipping marinade for ponzu and add 1 teaspoon chili oil or thinly sliced jalapeno for heat.
• Herb Crusted Ahi: Replace sesame seeds with a mix of chopped toasted pistachios and panko for a nutty crunch and herbaceous flavor.
• Sesame Ginger Bowl: Serve sliced tuna over steamed rice with quick pickled cucumbers and a drizzle of the marinade, turning it into a bowl meal.
• Gluten Free: Use tamari instead of soy sauce and ensure any added sauces are certified gluten free.

Make Ahead: You can make the marinade and toast the sesame seeds up to 2 days ahead, store them in an airtight container in the fridge, and slice the avocado just before serving. Do not marinate the tuna more than 20 minutes ahead; for safety and texture keep marinating to a short window and cook the tuna right before serving.
