- Sesame oil: Adds unmistakable nutty notes and silkiness seek out toasted sesame oil for maximum flavor
- Brown sugar: Brings a gentle sweetness that balances all the savory and bold components natural turbinado sugar works well too
- Garlic: Fresh and pressed is essential here or use a garlic press for the best results look for firm bulbs for flavor
- Ginger: Freshly grated delivers bright zesty bite and warmth the freshest ginger roots are smooth and taut
- White and black sesame seeds: Give a toasty crunch and beautiful finish and extra nutrition
- Salt and pepper to taste: Round out the flavors use flaked salt or freshly ground pepper for the best pop
- Tuna steaks: About half a pound each seek out sashimi-grade ahi tuna if you can as freshness makes all the difference
- Grapeseed oil: Has a high smoke point so it is ideal for that sizzling sear or substitute with avocado oil
Step-by-Step Instructions
- Mix the Marinade:
- In a mixing bowl combine soy sauce sesame oil brown sugar pressed garlic and grated ginger Stir briskly until the sugar is dissolved and the marinade is well blended Then set the sauce aside so the flavors can meld
- Prepare the Tuna Steaks:
- Carefully rinse the ahi tuna steaks with cool water then pat them fully dry with paper towels Season each steak on both sides with salt and pepper This ensures an even flavorful crust when seared
- Sear the Tuna:
- Heat a heavy skillet or cast iron pan over high heat Add the grapeseed oil and let it get almost smoking hot Gently lay a tuna steak in the pan You should hear a lively sizzling sound Cook undisturbed for two minutes allowing a flavorful crust to form

Storage Tips
Leftover sesame ginger ahi tuna keeps well in an airtight container in the fridge for up to two days I prefer to slice any leftovers and use them cold in salads for an easy lunch You can also make extra sauce and keep it chilled to drizzle over other proteins during the week for a burst of fresh flavor
Ingredient Substitutions
If you cannot find ahi tuna yellowfin or even high quality salmon can work in this recipe Rice vinegar is a good swap if you happen to run out of fresh ginger For a gluten free version use tamari instead of soy sauce and double check that your sesame oil is wheat free
Serving Suggestions
Serve the tuna steaks over steamed jasmine rice or nutty brown rice with a simple side of stir fried green beans For a lighter option try tucking thin slices into lettuce wraps with extra sauce and crunchy veggies Sometimes I turn leftovers into poke bowls with fresh cucumber radish and avocado for a truly satisfying meal

This recipe is a quick but memorable way to elevate weeknight dinners or impress guests with minimal effort.
