Instructions

  1. Step 1: Pat dry 4 sea bass fillets with paper towels. Season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat until shimmering. Place fillets skin side down and cook for 5-6 minutes without moving until skin is crisp and edges are golden.
  3. Step 3: Carefully flip fillets and cook an additional 2-3 minutes until the flesh is opaque and flakes easily.
  4. Step 4: Remove fish from pan and keep warm. Add remaining 1 tbsp olive oil to the skillet, then sauté 2 minced garlic cloves for 30 seconds until fragrant.
  5. Step 5: Add 1 1/2 cups quartered cherry tomatoes, 2 tbsp drained capers, 1 tbsp lemon juice, and 1/4 tsp red pepper flakes if using. Cook, stirring occasionally, for 3-4 minutes until tomatoes soften but retain shape.
  6. Step 6: Stir in 2 tbsp chopped fresh basil, then spoon the tomato-caper relish over the sea bass fillets before serving.

How do I store leftover Pan-Seared Sea Bass with Tomato-Caper Relish?

Can I substitute ingredients in Pan-Seared Sea Bass with Tomato-Caper Relish?
