How to Make Seared Ahi Tuna with Sesame, Avocado, and Asparagus Recipe
Step 1: Prepare the Tuna
First things first, pat your Ahi Tuna steak dry with paper towels to ensure a perfect sear. Brush the tuna lightly with ½ tablespoon of Dijon mustard—this acts like a glue to hold your sesame seeds in place and adds a subtle tang that complements the fish beautifully.
Step 2: Coat the Tuna in Sesame Seeds
In a shallow dish, mix together the white and black sesame seeds. Press each side of the mustard-coated tuna firmly into the sesame mixture until well covered. This double sesame crust will add a stunning contrast of colors and an irresistible nutty crunch once seared.
Step 3: Sear the Tuna
Heat a non-stick pan or cast-iron skillet over medium-high heat, adding a touch of sesame oil. When the oil is shimmering but not smoking, place the sesame-coated tuna in the pan. Sear for about one to two minutes on each side, depending on your preferred level of doneness. The goal is a crisp exterior with a rare to medium-rare center for that tender, buttery flavor.
Step 4: Prepare the Asparagus
While the tuna cooks, lightly steam or blanch your asparagus just until bright green and tender-crisp—about two to three minutes. This step keeps them vibrant, ensures they retain a nice snap, and pairs perfectly with the creamy avocado.
Step 5: Make the Dressing
In a small bowl, whisk together the soy sauce, 1½ tablespoons Dijon mustard, sesame oil, grated fresh ginger, lime juice, and honey until smooth. This dressing melds sweet, tangy, and savory flavors, which will bring your whole dish together beautifully.
Step 6: Assemble the Salad
On serving plates, lay down a bed of fresh arugula. Slice the avocado and arrange it alongside and atop the greens. Add the blanched asparagus in a neat row or scattered artfully. Slice the seared tuna into thick, juicy rounds and place over the veggies. Finally, drizzle with the dressing and add a small dollop of wasabi on the side if you like a little heat.

Garnishes
Fresh garnishes like thinly sliced scallions, toasted sesame seeds, or even finely shredded nori sheets elevate the dish with extra texture and visual appeal. A sprinkle of pink peppercorns can add a mild peppery note and a pop of color that’s simply irresistible.
Side Dishes
This dish is a showstopper on its own but pairs wonderfully with light sides such as steamed jasmine rice, a simple cucumber salad, or even a bowl of miso soup to complement the flavors without overpowering the delicate tuna.
Creative Ways to Present
For a fun twist, serve the tuna and salad atop crispy wonton chips for a crunchy base or roll the tuna slices and avocado in seaweed sheets for a sushi-inspired presentation. Serving in shallow bowls with the dressing pooled at the bottom creates a stunning, restaurant-worthy display.
Make Ahead and Storage
Storing Leftovers
If you manage to save any leftovers, store the tuna, veggies, and dressing separately in airtight containers in the refrigerator to maintain texture and freshness. The tuna is best eaten within 24 hours for optimal flavor and quality.
Freezing
Freezing seared tuna isn’t recommended because it can affect the texture and freshness. However, if you plan to freeze, do so only with raw ahi tuna before searing, and defrost gently overnight in the refrigerator before cooking fresh.
Reheating
Since seared ahi tuna is best served rare and fresh, avoid reheating the fish. Instead, enjoy leftover veggies and dressing cold or at room temperature, and if desired, quickly warm the asparagus in a pan just until heated through.
FAQs
Can I use a different type of tuna for this recipe?
Absolutely, but ahi tuna is preferred for its firm texture and mild flavor. Yellowfin or bigeye tuna work well, whereas lighter tunas might not hold up as crisply when seared.
What if I don’t have black sesame seeds?
No worries! You can use all white sesame seeds if that’s what you have on hand. The black seeds add a nice color contrast, but the flavor remains delicious with white seeds alone.
Is this recipe gluten-free?
It can be! Just be sure to use a gluten-free soy sauce or tamari when making the dressing to keep it safe for gluten-sensitive diets.
Can I prepare this recipe vegan?
This recipe centers around seared ahi tuna, so for vegans, you might try substituting with marinated tofu or seared king oyster mushrooms and keep the sesame, avocado, and asparagus elements intact for a similar taste profile.
How do I know when the tuna is cooked perfectly?
Tuna cooks very quickly and tastes best seared rare to medium-rare. Aim for about 1-2 minutes per side and look for a crust outside with a translucent pink center. Overcooking can make it dry and less flavorful.

- Adjust the searing time based on your preferred tuna doneness; ahi is best enjoyed rare to medium-rare.

- Fresh grated ginger enhances the dressing’s flavor but can be adjusted for spiciness.
- If asparagus is unavailable, substitute with green beans or snap peas for a similar crunch.
