Ingredients
- 4 fillets, about 6 oz each Chilean sea bass fillets
- 1 tsp salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 3 tbsp unsalted butter
- 2 cloves garlic cloves, minced
- 3 tbsp fresh lemon juice
- 2 tbsp fresh parsley, chopped
Instructions
- Step 1: Pat dry 4 Chilean sea bass fillets and season both sides evenly with 1 tsp salt and 1/2 tsp black pepper.
- Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat until shimmering. Add the fillets skin-side down and sear for 4-5 minutes without moving until the edges turn golden and crisp.
- Step 3: Flip the fillets carefully and add 3 tbsp unsalted butter and 2 minced garlic cloves to the pan. Spoon the melted butter and garlic over the fish as it cooks for another 3-4 minutes until the fish flakes easily with a fork.
- Step 4: Remove the fillets to a warm plate. Pour 3 tbsp fresh lemon juice into the skillet, stirring to deglaze and combine with the buttery pan juices. Pour this lemon butter sauce over the fish and sprinkle 2 tbsp chopped fresh parsley on top before serving.
