How to Make Fast & Easy Seared Tuna
Mix the sesame crust ingredients in a small bowl. Combine the sesame seeds, garlic powder, kosher salt, cracked pepper, sugar, and dried thyme until evenly blended. This mix will create that delightful crunch!
Pat dry the ahi tuna with paper towels. Gently pressing the tuna will help the sesame crust adhere better during cooking, ensuring maximum flavor and texture.
Coat the ahi tuna with soy sauce. Place it on a plate and evenly drizzle soy sauce over all sides, allowing the umami flavor to soak in for a few moments.
Sprinkle the sesame mix generously on all sides of the tuna. Press it firmly into the flesh so that it sticks well during searing, creating that irresistible crust.
Heat a cast-iron skillet over medium-high heat. Allow it to become very hot for an optimal searing experience, which is key to achieving that beautiful golden crust.
Add the oil to the hot pan. Make sure to coat the bottom of the skillet thoroughly, providing a non-stick surface for the tuna as it cooks.
Lay the tuna in the pan carefully. Using a metal spatula, gently press down the tuna to ensure proper contact with the hot surface, enhancing even cooking.
Sear for 45-60 seconds. Keep an eye on the tuna, and check for a golden color forming underneath before flipping it, as this indicates the perfect sear.
Flip the tuna carefully and sear the other side for 60-90 seconds. Wait until it takes on a lovely golden hue to ensure that gorgeous crust is formed all around.
Sear the long edges using tongs. Hold the tuna upright for a few seconds on each side to achieve an even crust all around, ensuring no part is left unseared.
Slice the tuna on a cutting board. If desired, blot any excess oil to keep the presentation neat, then cut into thin slices for serving.
Optional: Drizzle with a light soy sauce or wasabi for an extra flavor kick!

Fast & Easy Seared Tuna Recipe FAQs
How do I choose the right ahi tuna?
Absolutely! When selecting ahi tuna, look for a sushi-grade saku block with vibrant color, a firm texture, and no dark spots all over. The flesh should have a fresh, ocean-like scent. This quality ensures your dish is both safe and delicious!
How should I store leftover Fast & Easy Seared Tuna?
To keep your tuna fresh, store any leftovers in an airtight container in the fridge for up to 3 days. I often place a paper towel underneath the lid to absorb any excess moisture, preserving that delightful texture.
Can I freeze Fast & Easy Seared Tuna?
Yes, you can freeze it! Wrap the tuna tightly in plastic wrap or aluminum foil, then place it in a freezer-safe bag. This way, it can be stored for up to 2 months. When you re ready to enjoy it, thaw it in the fridge overnight for the best results.
What if my sesame crust falls off while cooking?
Very! If your crust doesn t adhere well, it could be because the tuna wasn t patted dry enough or the sesame mix wasn t pressed firmly enough onto the fish. Next time, ensure the tuna is completely dry, and press down firmly while coating it with the sesame mixture. Cooking on a well-heated pan will also help create a better bond!
Is this recipe safe for my pets?
While the ahi tuna itself is generally safe for pets in small amounts, be cautious with the seasoning. Avoid giving them soy sauce or any other high-sodium ingredients. If you want to share, offer a plain piece of seared tuna without the sesame crust as a special treat!
Can I use other types of fish for this recipe?
Absolutely! This method works beautifully with other firm, white fish like swordfish or salmon. Just adjust the searing time based on the thickness of the fillet, ensuring the inner fish is cooked to your desired level while still being moist and tender.
