Ingredients
Tuna and Marinade
- 2 (6 ounces each) fresh Ahi Tuna Steaks
- ¼ cup balsamic vinegar
- 1 tablespoon olive oil
- 1 tablespoon honey
- ½ teaspoon salt (divided)
Blackening Seasoning
- 1 teaspoon paprika
- ½ teaspoon cayenne pepper
- ½ teaspoon garlic powder
- ½ teaspoon dried thyme
- ½ teaspoon dried oregano
- ½ teaspoon salt (additional)
- ¼ teaspoon freshly ground black pepper
For Cooking
- 2 tablespoons vegetable oil
Instructions
- Prepare the Tuna: Pat dry the ahi tuna steaks with paper towels to remove excess moisture and place them in a large plastic zip-top bag.
- Mix Marinade: In a small mixing bowl, whisk together balsamic vinegar, olive oil, honey, and ½ teaspoon salt until well combined. Remove half of this mixture and transfer it to a small serving bowl for later use. Set aside.
- Marinate Tuna: Pour the remaining marinade into the plastic bag with the tuna steaks. Seal the bag and massage the marinade around the steaks to coat evenly. Let the tuna marinate for 10 minutes at room temperature or refrigerate up to overnight for deeper flavor.
- Prepare Blackening Spice Mix: In a small bowl, combine paprika, cayenne pepper, garlic powder, dried thyme, dried oregano, remaining ½ teaspoon salt, and freshly ground black pepper. Mix thoroughly.
- Season Tuna: Remove the tuna steaks from the marinade and discard the marinade. Sprinkle the seasoning mix evenly over all sides of each steak, pressing gently to help the spices adhere.
- Heat Skillet: Place a cast iron skillet over medium-high heat and allow it to become smoking hot. This ensures a proper sear and blackening effect.
- Cook Tuna: Add 2 tablespoons of vegetable oil to the hot skillet, swirling to coat the surface. Place the tuna steaks in the pan and cook for about 2 minutes on each side for medium rare. Adjust cooking time if you prefer a different doneness.
- Rest Tuna: Transfer the cooked tuna steaks to a cutting board and let them rest for 3 to 5 minutes to redistribute juices.
- Slice and Serve: Thinly slice the tuna steaks and serve topped with the reserved balsamic sauce for a delicious finishing touch.
Notes
- For stronger flavor, marinate the tuna overnight in the refrigerator.
- Use a cast iron skillet for best blackening results and heat retention.
- Adjust cayenne pepper amount if you prefer less spice.
- Ensure the skillet is smoking hot before adding tuna to get a proper crust.
- Serve with a side of steamed vegetables or a fresh salad for a balanced meal.
