Ingredients & Substitutions
Ingredient List
- 2 ahi tuna (yellowfin tuna) steaks (about 4 oz. each, 1 inch thick)
- 2 tablespoons soy sauce
- 1 tablespoon toasted sesame oil
- 1 tablespoon honey
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper (optional)
- 1 tablespoon canola or olive oil
- Green onions, toasted sesame seeds, and lime wedges for serving (optional)
Notes on Quality
For the best flavor and safety, opt for sushi-grade ahi tuna. Fresh, high-quality tuna will have a deep red color and a firm texture. If you can’t find sushi-grade, make sure you source it from a reputable fishmonger.
Possible Substitutions
- Soy sauce: Swap for tamari or coconut aminos for a gluten-free option
- Honey: Use maple syrup or agave for a vegan alternative
- Toasted sesame oil: Regular sesame oil works, but toasted provides a deeper flavor
- Canola oil: Substitute avocado oil for a healthier option
Step-by-Step Instructions
- Pat the tuna dry with a paper towel and place on a plate or in a plastic bag.
- Mix the marinade by combining soy sauce, toasted sesame oil, honey, kosher salt (omit if marinating longer than an hour), black pepper, and cayenne pepper. Stir until the honey is dissolved.

- Coat the tuna steaks with the marinade, ensuring they’re evenly covered. Let them sit for at least 10 minutes, or up to overnight in the fridge. Reserve some marinade for drizzling after cooking if desired.
- Heat a skillet (nonstick or well-seasoned cast iron) over medium-high to high heat until very hot. Cast iron needs about 3-5 minutes, while nonstick heats up in about a minute.
- Add the oil to the hot pan. Place the tuna steaks in the skillet and sear for 1–1½ minutes per side for medium-rare. Adjust the time based on thickness (see notes).
- Remove from heat and slice into ½-inch thick pieces. Garnish with green onions, toasted sesame seeds, and a squeeze of fresh lime juice.
Expert Tips & Tricks
Best Practices
- Use high heat to get a quick sear while keeping the inside tender and rare.
- Don’t overcook – ahi tuna is best enjoyed medium-rare or rare. Overcooking will make it dry.
- Slice immediately for a more rare center, or let it rest for a few minutes to allow carryover cooking.
Common Mistakes
- Marinating too long can make the tuna overly salty. If marinating for more than an hour, skip the added salt or use low-sodium soy sauce.
- Skipping the dry pat – excess moisture prevents a proper sear.
- Using low heat won’t give you that beautiful crust.
Time-Saving Tips
- Skip the marinade if in a rush – just season and sear for a simple and quick version.
- Make a dipping sauce ahead of time with soy sauce, sesame oil, honey, and a dash of sriracha.
Serving Suggestions
Pairings
Seared ahi tuna pairs well with:
- Steamed jasmine rice or coconut rice
- Asian-style slaw or sautéed bok choy
- Avocado slices and cucumber salad
Presentation Ideas
Arrange the sliced tuna on a platter, drizzle with reserved marinade or spicy mayo, and sprinkle with sesame seeds for an elegant look.
Beverage Pairings
- Wine: A crisp white wine like Sauvignon Blanc or a dry Riesling
- Cocktail: A refreshing ginger mule or sake-based cocktail
- Non-Alcoholic: Green tea or a citrus-infused sparkling water
Storage & Reheating
Leftover Storage
Store leftovers in an airtight container in the fridge for up to 2 days. Seared tuna is best enjoyed fresh, but it can also be used in salads or wraps the next day.
Reheating Methods
Reheating isn’t recommended, as it can dry out the tuna. Instead, enjoy it cold over salads or rice bowls.
Frequently Asked Questions
Can I use frozen tuna?
Yes! Just make sure to fully thaw it in the fridge overnight before cooking.
What if I don’t have toasted sesame oil?
Regular sesame oil or even olive oil will work, but toasted sesame oil adds a deeper, nutty flavor.
How can I make this spicier?
Add a pinch of red pepper flakes to the marinade or drizzle with sriracha before serving.

- Yield: 2 servings 1x
- Diet: Gluten Free
Description
These seared ahi tuna steaks take just six minutes to cook, giving you a restaurant-quality dish at home with minimal effort. Lightly marinated in soy sauce, toasted sesame oil, and honey, they develop a delicious umami flavor with a perfect golden crust while staying tender and rare inside. Serve them with a sprinkle of green onions, toasted sesame seeds, and fresh lime juice for an easy yet impressive meal.
Ingredients
- 2 ahi tuna (yellowfin tuna) steaks (about 4 oz. each, 1 inch thick)
- 2 tablespoons soy sauce
- 1 tablespoon toasted sesame oil
- 1 tablespoon honey
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper (optional)
- 1 tablespoon canola or olive oil
- Green onions, toasted sesame seeds, and lime wedges for serving (optional)
Instructions
- Pat the tuna steaks dry with a paper towel and place them on a plate or inside a plastic bag.
- In a small bowl, whisk together the soy sauce, toasted sesame oil, honey, kosher salt (omit if marinating longer than an hour), black pepper, and cayenne pepper until combined.
- Pour the marinade over the tuna steaks, ensuring they are evenly coated. Let them sit for at least 10 minutes or up to overnight in the refrigerator. Reserve a small amount of marinade for drizzling after cooking if desired.
- Heat a medium skillet (preferably nonstick or cast iron) over medium-high to high heat until very hot. If using cast iron, let it preheat for 3-5 minutes; for nonstick, 1 minute should be enough.
- Add the canola oil to the pan. Sear the tuna steaks for 1 – 1½ minutes per side for medium-rare, adjusting the time based on thickness.
- Remove from the heat and place the tuna on a cutting board. Slice into ½-inch thick pieces and serve immediately with green onions, toasted sesame seeds, and a squeeze of fresh lime juice.
Notes
- For different doneness: Less than 1 minute per side for very rare, up to 2½ minutes per side for medium-well.
- Sushi-grade recommended: For safety, opt for sushi-grade ahi tuna to reduce the risk of parasites.
- Gluten-free option: Use tamari or coconut aminos instead of soy sauce.
- Marination tip: If marinating for over an hour, omit the kosher salt to prevent the tuna from becoming too salty.
- Alternative cooking method: This recipe also works well on a hot grill—sear for about 1 minute per side over high heat.
- Carryover cooking: Tuna continues to cook slightly after removing it from the pan. Slice it right away for a more rare center, or let it rest for a slightly firmer texture.
