Ingredients

Instructions

  1. Step 1: Preheat the oven to 400°F. In a small bowl, combine 3 tablespoons olive oil, 3 minced garlic cloves, 1 cup halved cherry tomatoes, 1/2 cup sliced kalamata olives, 1 teaspoon dried oregano, 1 teaspoon salt, and 1/2 teaspoon black pepper. Stir to form the tomato-olive sauce.
  2. Step 2: Place 4 cod fillets (6 ounces each) in a single layer in a baking dish. Spoon the tomato-olive sauce evenly over each fillet, making sure to cover the fish well.
  3. Step 3: Sprinkle 1/2 cup crumbled feta cheese over the top of the sauced cod fillets. Bake uncovered in the oven for 15-18 minutes until the fish is opaque and flakes easily with a fork.
  4. Step 4: Remove from oven and garnish with 2 tablespoons chopped fresh basil. Serve immediately with lemon wedges on the side for squeezing over the fish to brighten flavors.
