Instructions

  1. Step 1: Pat dry 4 cod fillets with paper towels and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering. Add cod fillets and cook without moving for 4-5 minutes until golden and edges are crispy.
  3. Step 3: Carefully flip the cod and cook for another 3-4 minutes until fish flakes easily with a fork. Remove cod from skillet and keep warm.
  4. Step 4: In the same skillet, add 1 tbsp olive oil, then sauté 1 finely chopped shallot and 3 minced garlic cloves over medium heat for 2-3 minutes until translucent and fragrant.
  5. Step 5: Add 1 1/2 cups halved cherry tomatoes and 1/2 cup halved Kalamata olives. Cook for 5-6 minutes, stirring occasionally, until tomatoes soften and release juices.
  6. Step 6: Stir in 1/4 cup chopped fresh basil and 1 tbsp lemon juice. Adjust seasoning with more salt or pepper if desired.
  7. Step 7: Spoon the tomato-olive ragout over the cooked cod fillets and serve immediately.
