Recipe Information
Ingredients
- 2 pieces (6-8 ounces each) Tuna steaks
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 3 tablespoons Olive oil
- 2 tablespoons Butter
- 2 pieces Large yellow onions
- 3 tablespoons Balsamic vinegar
- 1.5 teaspoons Brown sugar
- 2 tablespoons Fresh parsley (optional, for garnish)
Instructions
1. Pat the tuna steaks dry with paper towels and season both sides with salt and black pepper. Let rest at room temperature for 10 minutes.
2. Peel and thinly slice the onions into half-moons.
3. Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet over medium heat. Add the sliced onions and stir to coat them evenly. Reduce the heat to medium-low and cook for 12-15 minutes, stirring occasionally, until the onions are softened and lightly caramelized.
4. Stir in the balsamic vinegar and brown sugar with the onions. Cook for another 3-4 minutes, until the onions are deeply caramelized and the mixture is thickened. Remove the onions from the pan and set aside.
5. Heat the remaining 2 tablespoons of olive oil in a clean skillet over medium-high heat. Once the oil is hot and shimmering, place the tuna steaks in the pan. Sear for 2-3 minutes per side for medium-rare doneness, or until cooked to your preferred level.
6. Remove the tuna steaks from the pan and let rest for 2 minutes.
7. Plate the tuna steaks and top with the sweet balsamic onions. Garnish with chopped fresh parsley if desired.
8. Serve immediately and enjoy this flavorful, elegant dish!
