Step-by-Step Instructions
Marinating the Ahi Tuna
First, we want to make the marinade. In a small bowl, mix together 2 tablespoons of soy sauce, 1 tablespoon of mirin, and 1 teaspoon of grated fresh ginger. This mix adds flavor and helps to keep the tuna moist. Place the 2 Ahi tuna steaks in a shallow dish. Pour the marinade over the steaks, making sure they are well coated. Let them sit for 15-20 minutes. This step allows the flavors to soak in.
Preparing the Sesame Coating
While the tuna marinates, it’s time to prep the sesame coating. Spread 1/4 cup of sesame seeds on a plate. You can use a mix of white and black seeds for a nice look. After the tuna has marinated, remove it from the dish. Carefully press each side of the tuna into the sesame seeds. Make sure the tuna is evenly coated. This will give the tuna a crunchy texture after cooking.
Searing the Tuna Steaks
Now let’s sear the tuna. Heat 1 tablespoon of olive oil and 1 tablespoon of sesame oil in a skillet over medium-high heat. Once the oil is hot, place the sesame-coated tuna steaks in the skillet. Sear each side for about 1-2 minutes if you want them rare. If you prefer them cooked more, adjust the time slightly. Once done, remove the tuna from the skillet and let it rest for 1-2 minutes. After resting, slice the tuna into 1/2 inch thick pieces. Arrange the slices on a plate. Serve them on a bed of mixed greens with sliced avocado. Don’t forget to top it with chopped green onions!
Tips & Tricks
Achieving the Perfect Crust
To get a great crust, use fresh sesame seeds. Mix white and black seeds for color. Spread them evenly on a plate. After marinating the Ahi tuna, press each side into the seeds firmly. This ensures an even coat. When you sear the tuna, make sure the oil is hot. This helps the crust become crispy.
Choosing the Right Ahi Tuna
Select Ahi tuna steaks that are bright in color and firm. Look for a deep red hue, which means freshness. The steaks should be at least an inch thick. This thickness helps achieve a nice sear while keeping the inside rare. If you can, buy sushi-grade tuna for the best taste and safety.
Adjusting Cooking Time for Doneness
Cooking time depends on how you like your tuna. For a rare finish, sear each side for 1-2 minutes. If you prefer it medium, increase the time to 3-4 minutes per side. Always check the center; it should remain pink. Let the tuna rest for a minute after cooking. This helps the juices settle, enhancing flavor.
Pro Tips
- Freshness is Key: Always choose the freshest Ahi tuna for the best flavor and texture. Look for bright red color and a firm texture when selecting your steaks.
- Adjusting Doneness: Sear the tuna for 1-2 minutes on each side for a rare finish. If you prefer it more cooked, increase the searing time gradually while keeping an eye on the color change.
- Marinade Time: Don't marinate the tuna for too long; 15-20 minutes is perfect. Over-marinating can make the fish mushy due to the acidity in the soy sauce and mirin.
- Serving Suggestions: Pair the sliced tuna with soy sauce or wasabi for an extra kick. Adding a sprinkle of sesame oil just before serving enhances the dish's flavor.
Variations
Alternative Marinades
You can change the flavor of your sesame crusted Ahi tuna with different marinades. Try a spicy marinade by adding sriracha or chili paste to the soy sauce. For a citrus twist, mix in fresh lime or orange juice. A honey-soy blend gives a sweet touch. Just keep the base of soy sauce for balance.
Serving Suggestions
Serve your tuna on a bed of mixed greens for a fresh crunch. Pair it with a tangy avocado salad for creaminess. You can also serve it with rice or quinoa for a heartier meal. Don’t forget to sprinkle some sesame seeds on top for extra flavor and texture.
Adding Nutritious Sides
Consider adding steamed vegetables like broccoli or snap peas. They add color and nutrients to your plate. A light cucumber salad with rice vinegar complements the dish well. You can also serve with a side of edamame for a protein boost. These sides make your meal balanced and tasty.
Storage Info
Storing Leftover Tuna
After cooking, allow the tuna to cool down to room temperature. Place it in an airtight container. You can keep the leftover tuna in the fridge for up to two days. Make sure to cover it well to keep it fresh. If you plan to eat it later, storing it properly is key to maintaining its flavor.
Reheating Recommendations
When you want to enjoy your leftover tuna, heat it gently. The best way is to use a skillet. Warm it over low heat for about one to two minutes. This helps to keep the tuna tender. You can also use the microwave, but be careful. Heat it in short bursts to avoid overcooking.
Freezing Instructions
If you want to save the tuna for later, freezing is a good option. Wrap it tightly in plastic wrap or foil. Then place it in a freezer bag. Make sure to squeeze out any air to prevent freezer burn. You can freeze it for up to three months. When ready to use, thaw it in the fridge overnight before reheating.
