Before diving into the phenomenon that is sesame-crusted tuna, let’s talk about what accompanies this dish beautifully. Pair it with a refreshing Asian slaw that complements the tuna’s flavors. Think of crunchy cabbage, carrots, and a light vinaigrette.
You could also serve it with jasmine rice or quinoa — both add a nice balance to the dinner plate. If you’re feeling adventurous, a chilled cucumber salad with sesame dressing could enhance the meal further. Whatever you choose, make sure it’s fresh and vibrant.
Introduction to Sesame Crusted Tuna

You’ll Also Like These Recipes
Now, let me take you on a journey of flavors and textures. When I first encountered sesame-crusted tuna, it was at a cozy seafood joint in my neighborhood. The dish caught my eye with its vibrant sear, gleaming sesame exterior, and vivid pink center. I couldn’t quite put my finger on what made it so magical.
After trying it, I was hooked. I knew I had to recreate this gem in my kitchen. With its nutty taste and a punch of umami from the sesame crust, I found it to be a delightful canvas for any side.
What is Sesame Crusted Tuna?
At its core, sesame-crusted tuna is an exquisite dish that features sushi-grade tuna enveloped in a crunchy mixture of sesame seeds. Typically, the tuna is seared quickly, allowing a beautiful crust to form while keeping the inside tender and rare. It’s not just a dish; it’s an experience. The preparation remains simple, yet it feels so sophisticated on the plate.
What is the Flavor Profile of This Dish?
The flavor profile is nothing short of delightful. Imagine the rich, buttery taste of fresh tuna paired with the nutty, roasted notes of sesame. There’s a slight sweetness from the sugar mixed into the crust, coupled with a touch of smokiness from the optional smoked paprika.
Every bite takes you on a journey: the crisp exterior gives way to the tender, melt-in-your-mouth fish. Not to mention, the umami from soy sauce rounds out the experience, making it anything but dull.
What Makes This Recipe Different From Other Sesame Crusted Tuna?
What sets this recipe apart is the combination of unique spices and the technique used for preparation. Many recipes just use sesame seeds, but I incorporate garlic powder for extra depth and dried thyme for an aromatic touch. Additionally, the choice of high-heat oil allows for a perfectly seared crust without compromising the delicate flavor of the fish. This recipe proves that simplicity can lead to spectacular results.
Ingredients You’ll Need
To craft this succulent dish, you will gather the following:
- 16 ounces sushi-grade ahi tuna, thawed (saku block)
- 2 tablespoons high-heat oil for searing (peanut, wok, or avocado oil)
- 1 tablespoon soy sauce or gluten-free liquid aminos
For the Sesame Crust:
- 1 teaspoon granulated sugar
- 1 teaspoon dried thyme
- 1/2 teaspoon smoked paprika (optional, for subtle warmth)
- 1 teaspoon freshly cracked black pepper
- 3 tablespoons sesame seeds (black, or a mix of black and white)
- 1 teaspoon granulated garlic powder (or onion powder)
- 3/4 teaspoon kosher salt
- 1 teaspoon toasted sesame oil (for extra nutty flavor)

Step by Step Directions
Step 1: Prepare the Tuna
Start with a high-quality piece of tuna. You want it fresh and sushi-grade. Trim off any sinew and pat it dry with paper towels. The key here is to ensure the tuna is free from moisture, facilitating that perfect crust.
Step 2: Mix the Sesame Crust
In a bowl, combine the sesame seeds, sugar, thyme, smoked paprika (if using), black pepper, garlic powder, salt, and toasted sesame oil. Give it a good mix. You want the flavors to marry beautifully before they meet the fish.
Step 3: Coat the Tuna
Dip the tuna in soy sauce to season it lightly. Then press the tuna into the sesame mixture, covering all sides evenly. The goal is to create a generous layer of that nutty goodness.
Step 4: Heat the Pan
In a skillet, heat the high-heat oil over medium-high flame. It should be hot but not smoking. If you’re not sure, flick a drop of water in the pan — if it sizzles, you’re good to go.
Step 5: Sear the Tuna
Once the oil is ready, add the coated tuna. Sear it for about one to two minutes per side, depending on how rare you like it. The outside should turn a beautiful golden brown while the inside remains a vibrant pink.
Step 6: Slice and Serve
Remove the tuna from the skillet and let it rest for a minute. Then slice it into even pieces. Serve it warm, maybe on top of a vibrant salad or alongside a refreshing side dish.
Tips On Making Sesame Crusted Tuna
Sourcing Quality Tuna: Always opt for sushi-grade tuna from a reliable fishmonger. Freshness is pivotal for flavor and safety.
Get the Pan Hot: Make sure your pan is hot enough. A searing pan prevents the crust from sticking and ensures a beautiful exterior.
Experiment with Seeds: Don’t limit yourself to just sesame seeds. Try adding crushed nuts for another layer of texture and flavor.
Thawing is Key: If using frozen tuna, defrost it slowly in the fridge overnight. Rapid thawing can alter the texture unfavorably.
Use a Timer: Timing the sear makes a difference. Set a timer to ensure consistency in cooking.

How Can I Store This Sesame Crusted Tuna?
Should you have leftovers, they can be stored in an airtight container in the fridge for up to 2 days. Make sure to let the tuna cool completely before sealing it to avoid steam buildup. Reheat gently in a skillet to retain its texture.

Substitutions for Ingredients
If you encounter a shortage in the kitchen, here are some substitutes that can work just as well:
Ahi Tuna: If you cannot find ahi tuna, use yellowfin tuna. It has a similar texture and flavor profile.
Soy Sauce: For a lighter alternative, consider coconut aminos. It’s a soy-free option with a slightly sweeter flavor.
High-Heat Oil: Instead of avocado oil, any neutral oil like canola or grapeseed can suffice without affecting taste.
Sesame Seeds: If sesame seeds are unavailable, you can use crushed pistachios for crunch and an alternative flavor.
