Oven-Baked Cod Fillet
Ingredients
- 4 cod fillets
- 3 tablespoons olive oil
- 2 garlic cloves minced
- 1 lemon juice + zest
- Salt and pepper
- Fresh herbs parsley, chives, or dill
- 4 lemon slices optional, for garnish
Instructions
Preheat the oven
- Preheat your oven to 400°F (200°C) so it’s fully heated before baking. This step is essential for even and quick cooking.
Prepare the cod fillets
- Rinse the fillets under cold water to remove any impurities, then pat them dry with paper towels. This helps prevent excess moisture and ensures even cooking.
Prepare the marinade
- In a small bowl, mix the olive oil, minced garlic, lemon juice, and zest. Add a pinch of salt and pepper. This mixture will gently flavor the cod.
Marinate the cod
- Place the fillets in a baking dish and generously brush them with the marinade, making sure all sides are well coated. Let them rest for 5 minutes so the flavors can absorb.
Add herbs and garnish
- Sprinkle the fillets with fresh herbs of your choice. If desired, place a slice of lemon on each fillet for an elegant presentation and an extra hint of acidity.
Bake
- Place the dish in the oven and bake for 12 to 15 minutes, until the fish is opaque and flakes easily with a fork.
Serve and enjoy
- Let the fillets rest for a few minutes after removing them from the oven. This allows the flavors to fully develop. Serve with steamed vegetables, rice, or mashed potatoes.
Storage
Cooked cod fillets can be stored in the refrigerator in an airtight container for up to 2 days. To reheat, use gentle heat in the oven to preserve their texture.
Mistakes to Avoid for Perfect Oven-Baked Cod Fillet
- Not preheating the oven
A cold oven prevents even cooking. Make sure to preheat it to 400°F (200°C) for tender, perfectly cooked cod. - Forgetting to pat the fillets dry
Rinsing the cod is important, but not drying it properly can result in steaming instead of a firm texture. - Underestimating the marinade
If the fillets are not well coated, the fish may lack flavor. Take the time to brush each fillet thoroughly. - Adding too much salt at the beginning
Cod is naturally slightly salty, so over-seasoning can throw off the balance. Taste the marinade before adding more salt. - Skipping fresh herbs
They’re not just for decoration! Fresh herbs add essential flavor. Don’t skip this step. - Overcooking
Overcooked cod becomes dry and loses its delicate texture. Stick to a cooking time of 12 to 15 minutes for best results. - Skipping the resting time
Not letting the fish rest after cooking can prevent the flavors from settling. Let it rest for about 5 minutes before serving.
