How to Cook Cod in the Oven

Name: How to Cook Cod in the Oven
Ingredients: 400 °F oven temperature; parchment paper or oil baking sheet preparation; paper towels for drying; to taste salt and pepper; optional garlic powder, paprika, or dried herbs; light coating olive oil or melted butter

Cod bakes beautifully at 400°F in 12-15 minutes. Pat the fillets dry, season them well, and place on a lightly oiled baking sheet. The fish is done when it flakes easily with a fork and reaches an internal temperature that feels firm to the touch.

Ingredients

400 °F oven temperature
parchment paper or oil baking sheet preparation
paper towels for drying
to taste salt and pepper
optional garlic powder, paprika, or dried herbs
light coating olive oil or melted butter

Step by step

Preheat your oven to 400°F. This temperature cooks the cod evenly without drying it out. Line a baking sheet with parchment paper or lightly oil it.
Pat the cod fillets completely dry. Use paper towels to remove all surface moisture. Wet fish steams instead of baking, and you want that gentle browning on the surface.
Season the fillets on both sides. Salt and pepper work perfectly, but you can add garlic powder, paprika, or dried herbs. Let the seasoning sit for 2-3 minutes to penetrate.
Place fillets on the prepared baking sheet. Leave space between each piece so they bake rather than steam. Brush the tops lightly with olive oil or melted butter.
Bake for 12-15 minutes. Thinner fillets need closer to 12 minutes, thicker pieces up to 15. The fish should look opaque and flake easily when tested with a fork.
Test for doneness. Gently press the thickest part with your finger. It should feel firm but still give slightly. The internal color should be completely opaque white.

Tips & troubleshooting

Choose fillets that are similar in thickness so they cook evenly
Never flip cod while baking - it's delicate and will break apart
If your fillets have skin, place them skin-side down and leave it on during cooking
Room temperature fish cooks more evenly than straight-from-the-fridge cold fillets
Save any leftover baked cod for fish cakes or salads the next day

Variations

Lemon Herb Cod. Add lemon slices on top and sprinkle with fresh thyme or dill before baking.
Parmesan Crusted. Mix breadcrumbs with grated Parmesan and herbs, then press onto the fillets before baking.
Mediterranean Style. Top with diced tomatoes, olives, and a drizzle of olive oil mixed with garlic.
Foil Packet Cod. Wrap each fillet with vegetables and seasonings in aluminum foil for steamed, tender results.

Questions

How do I know when cod is fully cooked?: The flesh turns completely opaque white and flakes easily when gently pressed with a fork. It should feel firm but not hard when you touch it.
Can I bake frozen cod fillets?: Yes, but add 5-7 extra minutes to the cooking time. Make sure to pat them dry once they thaw enough during the first few minutes of baking.
Why did my cod turn out dry?: Overcooking is the usual culprit. Cod continues cooking for a minute or two after you remove it from the oven, so take it out when it just barely flakes.
Should I remove the skin before baking?: You can leave it on - it helps hold the fillet together and peels off easily after cooking. If you prefer skinless, ask your fishmonger to remove it.
What temperature should the fish reach inside?: Focus on texture rather than exact temperature. When the fish feels firm and flakes easily, it's ready. Overcooked cod becomes rubbery quickly.
