How to Make Seared Ahi Tuna with Sesame Seeds, Avocado, and Arugula Recipe
Step 1: Prepare the Tuna
Start by patting your ahi tuna steak dry with paper towels—this helps achieve that perfect sear. Spread half a tablespoon of Dijon mustard evenly over the surface of the tuna. Then, coat the tuna with a mix of white and black sesame seeds, pressing them gently to make sure they stick. Sprinkle sea salt over the crust to enhance flavor.
Step 2: Sear the Tuna
Heat a non-stick skillet over medium-high heat. Once hot, add a small drizzle of oil to prevent sticking. Place the tuna steak in the pan and sear for about 1 to 2 minutes on each side—just enough to create a crunchy sesame crust while keeping the center rare and melt-in-your-mouth tender. Remove from heat and let it rest briefly before slicing thinly against the grain.
Step 3: Prepare the Asparagus and Salad
Trim and lightly steam or sauté the asparagus until just tender but still crisp, retaining its bright green color. Meanwhile, toss the fresh arugula with diced avocado. This combination adds peppery freshness and creamy richness that perfectly complements the tuna.
Step 4: Whip Up the Dressing
In a small bowl, whisk together low-sodium soy sauce, 1½ tablespoons Dijon mustard, sesame oil, grated fresh ginger, lime juice, and honey. This dressing is the secret ingredient that ties the whole dish together, delivering a balance of salty, sweet, tangy, and nutty flavors.
Step 5: Assemble the Dish
Arrange the arugula and avocado salad on plates, add the asparagus on the side, then neatly place slices of the sesame-crusted tuna on top. Drizzle the dressing over everything, and add a small dab of wasabi if you like a little heat with your meal.

Make Ahead and Storage
Storing Leftovers
If you have leftover Seared Ahi Tuna with Sesame Seeds, Avocado, and Arugula Recipe, store the tuna separately from the avocado and arugula in airtight containers in the refrigerator. The tuna should be eaten within 24 hours for the best texture and flavor, while avocados will brown quickly, so it’s best to enjoy them fresh.
Freezing
We do not recommend freezing this dish, as both the delicate tuna and creamy avocado lose their desirable texture once frozen and thawed. For the freshest experience, it’s best to consume it fresh or refrigerate leftovers for a short time only.
Reheating
Reheating seared ahi tuna is tricky because it’s best served rare or medium-rare. If needed, warm gently in a pan over low heat for a short time or enjoy the leftovers cold, which preserves the flavor and texture best.
FAQs
Can I use other types of fish for this recipe?
While ahi tuna is ideal for its texture and flavor, you can substitute with fresh yellowfin or even swordfish steaks, keeping in mind cooking times may vary to maintain the perfect rare center.
Is it necessary to use both white and black sesame seeds?
Using both adds a beautiful color contrast and a deeper nuttiness, but if you only have one type on hand, it will still taste wonderful.
How do I know when the tuna is perfectly seared?
The exterior should be golden and crusted with sesame seeds, while the inside remains pink and tender. Generally, a quick 1–2 minute sear per side on high heat is ideal.
Can I make this recipe vegan or vegetarian?
For a plant-based version, swap the tuna for marinated tofu or seared portobello mushrooms and keep the avocado and arugula components for a similarly fresh and satisfying dish.
What can I use instead of wasabi if I don’t like spicy heat?
If wasabi isn’t your thing, try a small sprinkle of freshly ground black pepper or a drizzle of a mild ginger dressing to keep some zing without the heat.
