Proper storage will ensure your leftover Oven-Baked Cod Fillets remain delicious for days to come.
- Refrigeration: Allow the cod to cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3 days.

- Reheating: Reheat the cod in the oven at 350°F (175°C) for 10-15 minutes, or until heated through. You can also reheat it in the microwave, but be careful not to overcook it.
Tips to Make This Oven-Baked Cod Fillets Recipe
Here are a few tips to ensure your Oven-Baked Cod Fillets turn out perfectly every time:
- Ingredient Swaps: Don’t have oregano or thyme? Use Italian seasoning instead. You can also substitute lime juice for lemon juice.
- Success Tips: Use fresh cod fillets for the best flavor and texture. Do not overcook the cod, as it will become dry and rubbery.
- Common Mistakes to Avoid: Avoid overcrowding the baking dish, as this can cause the cod to steam instead of bake. Also, be sure to pat the cod dry before seasoning it, as this will help it brown nicely.

Baking cod fillets at 400°F (200°C) typically yields the best results. This temperature ensures the cod cooks through while remaining moist and flaky.
How long do you bake cod fillets in the oven?
Cod fillets usually take between 12-15 minutes to bake at 400°F (200°C), depending on their thickness. Check for doneness when the fish flakes easily with a fork.

Simple seasonings like salt, pepper, lemon juice, and butter enhance the natural flavor of cod. You can also add herbs like parsley, dill, or thyme for extra flavor.
How do you keep cod fillets from drying out in the oven?
To prevent dryness, brush the cod fillets with melted butter or olive oil before baking. Covering the baking dish with foil for the first half of the baking time can also help retain moisture.
