Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Place 4 cod fillets in a baking dish, brush with 2 tablespoons avocado oil, and top with 1 thinly sliced lemon; season with 1/4 teaspoon sea salt and 1/4 teaspoon black pepper.
  2. Step 2: Bake for 12-15 minutes until the fish is opaque and flakes easily with a fork, checking at 12 minutes to avoid overcooking.
  3. Step 3: While fish bakes, combine 1/4 cup fresh dill and 1 tablespoon lemon juice in a small bowl; once fish is done, spoon the dill mixture over the top and serve immediately to maximize freshness and flavor.

How do I store leftover Oven-Baked Cod with Lemon-Dill Sauce?
