Let’s Talk Tuna: Sourcing Tips
The key to a perfect sesame crusted tuna steak starts with the fish itself. Fresh, sushi-grade tuna is what you’re after. Check your local fishmonger, Whole Foods, or trusted seafood counter. Look for tuna steaks that are bright red, firm to the touch, and smell clean—not fishy.
If you live near the coast, even better. Hit up your local seafood market for the freshest catch.
Tips & Tricks For Perfect Sesame Crusted Tuna Steak
Use a Heavy Skillet: A cast iron or stainless steel pan holds heat well and gives you an even sear.
Don’t Overcook the Tuna: It’s best enjoyed rare to medium-rare. Anything more, and you risk a dry texture.
Press the Sesame Seeds Firmly: Make sure the seeds are packed on well before searing to prevent them from falling off in the pan.
Let the Tuna Rest: Even a short minute of resting helps retain the juices.
Pair with Fresh Greens: The crisp, slightly acidic salad balances the rich, nutty flavors perfectly.
Ingredient Substitutions (Easy Swaps)
No Black Sesame Seeds? Use all white sesame seeds. It’s just as tasty.
No Gluten-Free Soy Sauce? Coconut aminos or tamari work great.
Want a Different Salad? Try adding cherry tomatoes, thin apple slices, or even a bit of pickled ginger.
Why Fresh, Local Ingredients Matter
When you use fresh, locally sourced produce and seafood, you’re not only supporting local farmers and fishers, but you’re also giving yourself the best flavor possible.
That cucumber from your local market? Crisp and sweet. The radishes? Peppery with a satisfying crunch. The tuna? Freshly caught and never frozen. It’s the difference between a good dish and an unforgettable one.
Plus, shopping local reduces unnecessary packaging and transport, making it a win for the environment too.
Serving Suggestions
This sesame crusted tuna steak pairs beautifully with:
Steamed jasmine rice or cauliflower rice if you want something extra on the side.
Miso soup for a light starter.
A crisp glass of sauvignon blanc or a cold iced tea.

Gluten-Free Sesame Crusted Tuna Steak
- Total Time: 15 minutes
- Yield: 2 servings 1x
- Diet: Gluten Free
Description
A crispy, golden sesame crust gives these tuna steaks a restaurant-quality flavor and texture, while keeping it 100% gluten-free. Quick to make, high in protein, and perfect for a fresh, healthy dinner.
Ingredients
For the Tuna Steaks:
2 fresh yellowfin or ahi tuna steaks (about 6 oz each, sushi-grade if possible)
¼ cup white sesame seeds
¼ cup black sesame seeds (optional, but adds color and extra flavor)
1 tablespoon gluten-free soy sauce (or coconut aminos)
1 teaspoon toasted sesame oil
1 teaspoon fresh lime juice
1 tablespoon olive oil (for searing)
Kosher salt and cracked black pepper
For the Simple Salad:
2 cups mixed baby greens (local spring mix or arugula is great)
1 avocado, sliced
4–5 radishes, thinly sliced
1 small cucumber, sliced thin
½ cup shredded carrots
1 tablespoon rice vinegar
1 tablespoon olive oil
Pinch of salt and pepper
Instructions
First, pat the tuna steaks dry with paper towels. Moisture is the enemy of a good sear.
In a small bowl, whisk together the gluten-free soy sauce, sesame oil, lime juice, salt, and pepper. Brush both sides of the tuna steaks generously with this marinade. Let them sit for about 10 minutes while you prepare the crust.
In a shallow plate, combine the white and black sesame seeds. Press each tuna steak firmly into the sesame seeds on both sides, making sure they stick well. Don’t be shy—get a nice even layer.
Heat a non-stick skillet or cast iron pan over medium-high heat. Add the olive oil and let it get hot, shimmering but not smoking.
Carefully place the tuna steaks in the pan. Sear for about 1-2 minutes per side for rare (you’ll get that gorgeous pink center), or up to 3 minutes per side if you prefer more doneness.
Pro tip: Resist the urge to move the tuna around. Let it develop a nice golden crust.
Once done, remove the steaks and let them rest for a minute while you toss the salad.
In a large bowl, toss together the mixed greens, cucumber slices, radishes, shredded carrots, and avocado.
Drizzle with rice vinegar and olive oil. Add a pinch of salt and cracked pepper. Give it a quick toss.
This salad is light, crisp, and balances the richness of the tuna beautifully.
Slice the tuna steaks against the grain into ½-inch thick slices. You’ll see that perfect pink center surrounded by the golden sesame crust.
Arrange a handful of salad on each plate, then fan out the tuna slices on top or alongside. For an extra pop of flavor, drizzle a little more gluten-free soy sauce or a squeeze of lime juice over the top.
Serve immediately and enjoy every bite.
Notes
Make sure to use sushi-grade tuna for best results. Fresh, local veggies like cucumbers, radishes, and spring greens pair beautifully with the rich tuna. You can also serve it over rice or gluten-free noodles. Feel free to swap tamari for soy sauce to keep it gluten-free.
