This lemon garlic swordfish is pan-seared until golden and finished in the oven, then topped with a bright, buttery lemon-garlic sauce. It’s a simple, elegant seafood dish that comes together quickly for a fresh and flavorful dinner.

Ingredients

  • 2 tablespoons salted butter (softened to room temperature)
  • 1 tablespoon freshly chopped chives
  • 2 tablespoons garlic cloves (minced)
  • 1/8 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon grated lemon peel
  • 2 tablespoons olive oil
  • 2 swordfish fillets (1-inch thick, about 67 oz each)
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste

Instructions

  1. Preheat the oven to 400°F with a rack in the middle position.
  2. In a small pan, combine the softened butter, chives, minced garlic, 1/8 teaspoon kosher salt, 1/4 teaspoon black pepper, lemon juice, and lemon zest. Stir until fully combined and set aside.
  3. Pat the swordfish fillets dry with paper towels, then season both sides with kosher salt and freshly ground black pepper.
  4. Heat olive oil in a large oven-safe skillet over medium-high heat. Once hot, add the swordfish and sear for about 3 minutes until browned on one side. Flip carefully.
  5. Turn off the stovetop heat and transfer the skillet to the preheated oven. Roast for 5–6 minutes, or until the fish is just cooked through.
  6. While the fish finishes cooking, warm the lemon-garlic butter mixture over medium-high heat until melted and bubbly, stirring constantly.
  7. Remove the swordfish from the oven and immediately pour the lemon-garlic butter sauce over the fillets, including any pan juices.

Notes

  • Do not overcook swordfish; it should remain moist and just opaque in the center.
  • Use fresh lemon zest for the brightest flavor.
  • A cast iron or oven-safe stainless steel skillet works best for this recipe.
  • Serve with rice, roasted vegetables, or a light salad.
