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

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.

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.
