Ingredients
- 4 fillets, 6 oz each sea bass fillets
- 1 tsp sea salt
- 1/2 tsp, freshly ground black pepper
- 6 tbsp unsalted butter
- 2 tbsp fresh lemon juice
- 2 tbsp, drained capers
- 2 tbsp olive oil
- 2 tbsp, chopped fresh parsley
Instructions
- Step 1: Pat dry 4 sea bass fillets (6 oz each) and season both sides with 1 tsp sea salt and 1/2 tsp freshly ground black pepper.
- Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat until shimmering. Place the fillets skin-side down and sear for 4-5 minutes until the skin is crisp and golden.
- Step 3: Flip the fillets and cook for an additional 2-3 minutes until the fish is opaque and flakes easily with a fork. Remove fillets to a warm plate.
- Step 4: Reduce heat to medium and add 6 tbsp unsalted butter to the skillet. Cook, swirling occasionally, until the butter turns golden brown and smells nutty, about 3-4 minutes.
- Step 5: Stir in 2 tbsp fresh lemon juice and 2 tbsp drained capers, cooking for 1 minute until the sauce slightly thickens.
- Step 6: Spoon the lemon-caper brown butter sauce over the sea bass fillets and garnish with 2 tbsp chopped fresh parsley before serving immediately.
