Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat sea bass fillets dry and rub with 1 tbsp olive oil, then season with 1/4 tsp kosher salt and 1/8 tsp black pepper on both sides.
  2. Step 2: Place fillets in a baking dish and top with 1/2 thinly sliced lemon (skin removed), 1 tbsp capers, and 1 tbsp fresh dill.
  3. Step 3: Bake for 12-14 minutes until the fish flakes easily with a fork and the edges are golden brown.
  4. Step 4: Remove from oven and spoon off excess liquid, then transfer to a plate. Add 2 tbsp dry white wine to the baking dish and simmer over medium heat for 2 minutes until reduced by half.
  5. Step 5: Stir in 1 tbsp butter until melted and glossy, then pour the sauce over the fish just before serving, ensuring the sauce coats the fish evenly and gleams like sunlight on water.
