Ingredients
  

  • 4 fillets fresh cod fillets bright, firm flesh, skin optional
  • 1 lemon lemon freshly squeezed for juice, zest optional
  • 2 tablespoons good-quality extra virgin olive oil for drizzling and flavor
  • 3 cloves garlic finely chopped or crushed
  • 1 teaspoon dried or fresh thyme substitute with parsley if desired
  • to taste flaky sea salt and freshly cracked black pepper
  • a splash of white wine or broth white wine or broth optional for added moisture

Equipment

  • Baking dish
  • Paper towels
  • Lemon squeezer
  • Sharp Knife
  • Aluminum foil
  • Kitchen thermometer

Method
 

  1. Preheat your oven to 150°C (300°F). Place a baking dish in the oven while it heats to ensure even cooking temperature.
  2. Pat the cod fillets dry with paper towels to remove excess moisture, which helps achieve even seasoning and prevents steaming during baking. Arrange the fillets skin-side down in the prepared baking dish.
  3. Drizzle the olive oil evenly over the fillets, gently massaging it into the flesh. This adds moisture and helps the seasonings stick.
  4. Squeeze the fresh lemon juice over the fish, letting it pool slightly on the surface. Sprinkle the chopped garlic and thyme evenly across the fillets for aromatic flavor.
  5. If using, pour a splash of white wine or broth into the dish to add moisture and subtle flavor. Cover the dish loosely with aluminum foil to trap steam.
  6. Place the dish in the preheated oven and bake for 20 to 25 minutes. Check after 15 minutes; the fish should be slightly opaque around the edges and gently bubbling.
  7. Test for doneness by gently jiggling the fillet; it should flake easily with a fork and feel tender in the center. The internal temperature should reach about 52°C (125°F).
  8. Remove the fish from the oven and let it rest uncovered for 3 to 5 minutes. This helps the juices redistribute, keeping the fish moist and tender.
  9. Squeeze a final splash of lemon over the fillets and sprinkle with fresh herbs if desired. Serve immediately with your favorite sides for a bright, elegant meal.

Notes

For extra flavor, add a few sprigs of fresh herbs on top before baking. Adjust cooking time based on the thickness of your fillets, and always check for flakiness and internal temperature for perfect results.
