Ingredients
- 2 (6-ounce) ahi tuna steaks, sushi-grade, about 1-inch thick
- 1 tablespoon sesame oil
- 1 tablespoon olive oil
- 1 teaspoon soy sauce (or tamari for gluten-free)
- 1/2 teaspoon grated fresh ginger
- 1 clove garlic, minced
- 1/4 teaspoon black pepper
- Optional: sesame seeds for garnish
- Optional: sliced green onions for garnish
Instructions
- Pat the tuna steaks completely dry with paper towels. This is crucial for achieving a good sear.
- In a small bowl, whisk together the sesame oil, olive oil, soy sauce, grated ginger, minced garlic, and black pepper. This will be your quick marinade and searing oil.
- Heat a cast iron skillet or heavy-bottomed frying pan over medium-high heat until very hot. You want it to be hot enough to sear the tuna instantly.
- Carefully place the tuna steaks into the hot skillet. Sear for 60-90 seconds per side for rare (cool red center), 90-120 seconds per side for medium-rare (warm red center). Adjust time based on thickness and desired doneness. Avoid overcooking, as tuna can become dry.
- While the tuna is searing, you can spoon some of the oil mixture from the pan over the top of the steaks if desired.
- Once seared to your liking, immediately remove the tuna steaks from the skillet and place them on a clean cutting board.
- Let the tuna rest for 1-2 minutes before slicing. This allows the juices to redistribute.
- Slice the tuna steaks against the grain into 1/2-inch thick pieces. Garnish with sesame seeds and sliced green onions, if using.
Tips
- Use sushi-grade tuna for the best flavor and texture. If unsure, ask your fishmonger.
- Ensure your skillet is smoking hot before adding the tuna. This is key for that beautiful crust.
- Do not overcrowd the pan. Cook tuna steaks in batches if necessary.
- Don’t overcook! Tuna is best served rare to medium-rare.
- Patting the tuna dry is non-negotiable for a good sear.
Serving Suggestions
- Serve over a bed of fluffy jasmine rice or quinoa.
- Pair with a side of steamed or roasted vegetables like broccoli, asparagus, or edamame.
- Drizzle with a bit of extra soy sauce, ponzu sauce, or a spicy mayo.
- Incorporate into a poke bowl or a vibrant salad.
- Serve as an appetizer with a wasabi and soy dipping sauce.
Storage Tips
Cooked ahi tuna is best enjoyed immediately. If you have leftovers, store them in an airtight container in the refrigerator for up to 1-2 days. Reheat gently or enjoy cold in salads or sandwiches.
FAQ
How do I know if my tuna is sushi-grade?
Sushi-grade means the fish is high quality and safe to eat raw. Look for vibrant color and a fresh ocean smell. When in doubt, ask your fishmonger.
Can I marinate the tuna for longer?
While a quick sear is ideal, you can marinate the tuna for up to 30 minutes in the refrigerator. Longer marination can ‘cook’ the fish with the acid and alter the texture.
What if I don’t have sesame oil?
You can use all olive oil, but the sesame oil adds a lovely nutty flavor. A combination of the two is recommended.
How do I prevent my tuna from overcooking?
Use a timer and know your desired doneness. Tuna cooks very quickly. Remove it from the heat when it’s still slightly under your target as it will continue to cook from residual heat.
