Step-By-Step Directions

  1. Preheat your oven to 450°F (232°C).

Helpful Tips for Perfect Mediterranean Baked Cod

  • Use Fresh Cod: If using frozen cod, thaw it completely and pat dry before seasoning to ensure even cooking and flavor absorption.
  • Don’t Overcook: Cod cooks quickly; 12–15 minutes is usually sufficient. Check for opacity and flakiness.
  • Veggie Variations: Add zucchini, spinach, or olives for variety. Experiment with your favorite Mediterranean vegetables.
  • Herb Additions: Substitute thyme with oregano, dill, or basil according to preference.
  • Extra Flavor: Finish with a drizzle of quality extra virgin olive oil and fresh lemon juice.

Make It Your Own: Customization Ideas

  • Swap the fish: Use halibut, snapper, or haddock if cod isn’t available.
  • Add olives: Toss in Kalamata or green olives for a briny touch.
  • Include leafy greens: Spinach or Swiss chard can be added for color and vitamins.
  • Make it spicy: Sprinkle with red pepper flakes during roasting for a mild kick.
  • Top with nuts: Toasted walnuts or pine nuts give extra crunch and richness.

Storing and Reheating Leftovers

  • Allow leftovers to cool to room temperature.
  • Store in an airtight container in the refrigerator up to 2 days.
  • To reheat, use a low oven (300°F/150°C) for 5–7 minutes until heated through. Avoid microwaving, which may dry out the fish.
