- ¼ cup white sesame seeds
- ¼ cup black sesame seeds
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper

- 1 tablespoon rice vinegar
- 1 teaspoon honey
- 1 teaspoon fresh ginger, grated
- 1 clove garlic, minced
- 1 green onion, thinly sliced
- ½ teaspoon sesame oil
- Pinch of red pepper flakes (optional)
✔ Directions :
– Preparing the Tuna:
1- Remove the tuna steaks from the refrigerator and let them rest at room temperature for 20 minutes.
2- Pat the tuna steaks completely dry with paper towels. This is crucial for achieving a perfect sear.
3- Brush each tuna steak lightly with sesame oil on all sides.
4- In a shallow dish, combine the white and black sesame seeds, salt, and pepper.
5- Press the tuna steaks into the sesame seed mixture, coating all sides evenly. Apply gentle pressure to ensure the seeds adhere well.
– Making the Dipping Sauce:
1- In a small bowl, whisk together soy sauce, rice vinegar, honey, grated ginger, minced garlic, green onion, sesame oil, and red pepper flakes (if using).
2- Set aside to allow flavors to meld while you cook the tuna.
– Searing the Tuna:
1- Heat a heavy-bottomed skillet (preferably cast iron) over high heat until it’s very hot, about 2 minutes.
2- Add 1 tablespoon of sesame oil to the pan and swirl to coat.
3- Carefully place the sesame-crusted tuna steaks in the hot pan.
4- Sear for exactly 1½ minutes on each side for rare, or 2 minutes for medium-rare. Also sear the edges for about 30 seconds each.
5- Immediately remove from heat and transfer to a cutting board.
6- Let the tuna rest for 2 minutes before slicing.
7- Using a sharp knife, slice the tuna against the grain into ½-inch thick pieces.

✔ Frequently Asked Questions :
How do I know if my tuna is fresh enough for searing?
Fresh ahi tuna should have a bright, clean ocean smell (not fishy), appear moist with a deep red or pink color, and have a firm texture. When purchasing, ask for “sashimi-grade” or “sushi-grade” tuna, which is the highest quality and safest for consuming rare or raw. Always buy from a reputable fishmonger or grocery store with high turnover for the freshest options.Can I cook the tuna all the way through?
While you can cook tuna to well-done if preferred, ahi tuna is traditionally served rare to medium-rare to preserve its tender texture and delicate flavor. Cooking it all the way through often results in dry, tough meat and diminishes the quality of this premium fish. If you’re uncomfortable with rare fish, consider trying a different type of seafood that’s better suited for thorough cooking.What can I serve with seared ahi tuna?
Seared ahi tuna pairs beautifully with Asian-inspired sides like wasabi mashed potatoes, sticky rice, or soba noodle salad. For vegetables, consider steamed bok choy, a cucumber-avocado salad, or stir-fried broccoli with ginger. A simple mixed green salad with a sesame-ginger dressing also makes an excellent accompaniment. reheated.How long will leftover seared tuna keep in the refrigerator?
Leftover seared tuna is best consumed within 24 hours for optimal flavor and food safety. Store it in an airtight container in the coldest part of your refrigerator. Avoid reheating leftover tuna as it will continue to cook and become dry. Instead, enjoy it cold in a salad or wrap.Can I use frozen ahi tuna for this recipe?
Yes, you can use frozen ahi tuna, but for best results, look for flash-frozen sashimi-grade tuna. Thaw it slowly in the refrigerator overnight, not at room temperature. Once thawed, pat it very dry before coating with sesame seeds, as excess moisture will prevent a good sear and cause the sesame seeds to steam rather than crisp.
✔ Tools You’ll Need :
- Heavy-bottomed skillet or cast iron pan
- Sharp chef’s knife
- Cutting board
- Small mixing bowl for the sauce
- Shallow dish for the sesame seed mixture
- Measuring cups and spoons
- Kitchen tongs
- Paper towels
- Instant-read thermometer (optional)
✔ Tips for success :
- The key to perfect seared tuna is a blazing hot pan. Let your skillet heat thoroughly before adding the tuna.
- Don’t move the tuna once it’s in the pan until it’s time to flip it. This ensures a proper crust forms.
- Use a timer rather than guessing the cooking time. Just 30 seconds too long can take your tuna from perfect to overcooked.
- For a more budget-friendly option, you can use yellowfin tuna instead of bluefin ahi tuna.
- If you’re concerned about the tuna being too rare, use an instant-read thermometer. The center should register around 110°F (43°C) for rare and 120°F (49°C) for medium-rare.
- For an extra flavor boost, marinate the tuna for 30 minutes before coating with sesame seeds. A simple marinade of soy sauce, sesame oil, and ginger works wonderfully.
