Ingredients
- 2 (6-ounce) sushi-grade ahi tuna steaks, about 1.5 inches thick
- 2 tablespoons soy sauce (or tamari for gluten-free)
- 1 tablespoon sesame oil
- 1 teaspoon grated fresh ginger
- 1 clove garlic, minced
- 1/2 teaspoon honey or maple syrup (optional, for a touch of sweetness)
- 1 tablespoon olive oil or other high-heat cooking oil
- 1 teaspoon black sesame seeds (for garnish)
- 1 teaspoon white sesame seeds (for garnish)
- Optional: Pinch of red pepper flakes
Instructions
- In a shallow dish, whisk together the soy sauce, sesame oil, grated ginger, minced garlic, honey (if using), and red pepper flakes (if using).
- Place the tuna steaks in the marinade, ensuring they are coated on all sides. Let them marinate for at least 15 minutes at room temperature, or up to 30 minutes in the refrigerator. Do not marinate for too long, as the acid in the soy sauce can start to ‘cook’ the fish.
- Remove the tuna from the marinade, letting any excess drip off. Pat the steaks gently with a paper towel to remove excess moisture; this helps create a better sear.
- Heat the olive oil in a heavy-bottomed skillet (like cast iron) over medium-high heat until it shimmers but isn’t smoking. The pan needs to be very hot.
- Carefully place the tuna steaks in the hot skillet. Sear for 1 to 2 minutes per side for rare (a deep red center), or 2-3 minutes per side for medium-rare (a slightly pinker center). Adjust cooking time based on the thickness of your steaks and your desired doneness. Avoid overcooking, as tuna can become dry.
- Once seared to your liking, remove the tuna steaks from the skillet and let them rest on a cutting board for about 5 minutes. This allows the juices to redistribute.
- Slice the tuna steaks against the grain into 1/2-inch thick pieces. Sprinkle with sesame seeds before serving.
Tips
- Use only sushi-grade or sashimi-grade tuna. This ensures it’s safe to eat raw or lightly seared.
- Don’t overcrowd the pan. If searing more than two steaks, do it in batches.
- A very hot pan is crucial for a good sear. If your pan isn’t hot enough, the tuna will steam instead of sear.
- Patting the tuna dry before searing is key to achieving a nice crust.
Serving Suggestions
- Serve sliced tuna over a bed of sushi rice or quinoa.
- Pair with a vibrant Asian-inspired slaw or a simple side of steamed edamame.
- Drizzle with a bit of extra soy sauce, wasabi, or a spicy mayo.
- Incorporate into salads for a protein-packed meal.
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 very gently or enjoy cold in salads.
FAQ
What does ‘sushi-grade’ tuna mean? Sushi-grade indicates that the fish is high quality and has been handled with specific safety precautions, making it suitable for raw consumption.
Can I marinate the tuna longer? It’s best not to marinate for much longer than 30 minutes, as the soy sauce can begin to ‘cook’ or toughen the delicate tuna flesh.
How do I know when the tuna is done? For rare, the center should be deep red. For medium-rare, it will be pink. The outside should have a nice seared crust.
