Key Ingredients

• 2 swordfish fillets (1-inch thick, about 6-7 ounces each)

• 1/2 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 2 tablespoons salted butter, softened
• 1 tablespoon fresh lemon juice
• 1 tablespoon grated lemon zest
• 2 cloves garlic, minced
• 1 tablespoon fresh chives, chopped

Step-by-Step Instructions

1. Preheat your oven to 400°F with the rack positioned in the middle.
2. Use paper towels to pat the swordfish fillets completely dry on all sides to ensure a good sear.

5. Heat olive oil in a large oven-proof skillet over medium-high heat until the oil is shimmering.
6. Place the swordfish in the skillet and sear undisturbed for 3 minutes until the bottom is golden brown.
7. Carefully flip the fillets over, turn off the stovetop burner, and immediately transfer the skillet into the preheated oven.
8. Bake for 5 to 6 minutes, or until the fish reaches an internal temperature of 130-135°F and the center is just cooked through.
9. Remove the skillet from the oven and immediately top each hot fillet with a generous dollop of the prepared lemon butter mixture.
10. Allow the butter to melt over the fish for 1 minute before serving.
