Instructions

  1. Step 1: Pat dry 4 cod fillets and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium heat until shimmering.
  2. Step 2: Add the cod fillets and cook for 4-5 minutes per side until opaque and flakes easily with a fork. Remove cod from skillet and keep warm.
  3. Step 3: In the same skillet, add remaining 2 tbsp olive oil and sauté 3 minced garlic cloves for 30 seconds until fragrant.
  4. Step 4: Add 1 1/2 cups quartered cherry tomatoes, 1/2 cup halved kalamata olives, and 2 tbsp drained capers. Season with remaining 1/2 tsp sea salt and 1/4 tsp black pepper. Cook for 5 minutes until tomatoes soften and sauce thickens slightly.
  5. Step 5: Spoon the tomato-olive-caper sauce over the cod fillets, sprinkle 2 tbsp chopped fresh parsley on top, and serve immediately with lemon wedges.
