Instructions

Step 1: Pat dry 4 grouper fillets (6 oz each) and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 3 tbsp olive oil in a large skillet over medium-high heat until shimmering.
Step 2: Place the fillets in the skillet and cook for 4 minutes on one side without moving, until the edges are golden and the fish releases easily from the pan.
Step 3: Flip the fillets and cook for an additional 3 minutes until the fish is opaque and flakes easily with a fork; remove from skillet and keep warm.
Step 4: Reduce heat to medium-low and add 4 tbsp unsalted butter to the skillet. Once melted, stir in 3 tbsp fresh lemon juice and 2 tbsp drained capers; cook for 1-2 minutes until the sauce thickens slightly and becomes glossy.
Step 5: Pour the lemon-caper butter sauce over the grouper fillets and sprinkle with 2 tbsp chopped fresh parsley before serving.
