Common Questions
How do I know when cod is done?
It is done when it turns opaque and flakes easily with a fork. If you use a thermometer, the USDA guideline for fish is 145°F in the thickest part. If you like it a touch juicier, you can pull it at 140°F and let it rest for 2 minutes to finish gently.
Why did my baked cod turn out rubbery or dry?
Usually it is overcooked. Cod is lean, so extra minutes matter. Also check thickness. Thin fillets may need only 8 to 10 minutes, while thick center cuts can take 12 to 15.
Can I use frozen cod?
Yes. Thaw overnight in the fridge, then drain and pat very dry. Some fillets are lightly brined and will weep liquid, so blot again right before seasoning. If you are in a hurry, thaw in a sealed bag in cold water, changing the water every 20 to 30 minutes. Avoid baking from frozen for this recipe because the fish releases water and the seasoning gets diluted.
What is the best oven temperature for flaky cod?
425°F is my sweet spot: hot enough for a little browning, fast enough to keep the inside juicy.
Can I make it dairy-free?
Swap the butter for more olive oil, or use a plant-based butter. Add an extra squeeze of lemon at the end to keep the flavor punchy.
What should I serve with oven-baked cod?
Anything that likes lemon-butter: roasted potatoes, rice, couscous, or a big crunchy salad. Also: crusty bread for sauce cleanup, because we are civilized.
