How to Bake Cod in The Oven

This recipe uses only four ingredients: cod fillets, butter, garlic parsley salt, and lemon.

Clean the cod fish: Pat the cod fillets dry with paper towels to remove excess moisture. Dry fish means no steaming!
Assemble the cod in the baking dish: Place butter pats at the bottom of a baking dish. Top them with the cod fillets then season with garlic parsley salt. Add another layer of butter and then lemon slices on top.
Bake the cod: Bake at 425°F for about 15 minutes. The high heat keeps the fish moist and tender.

Serving suggestions: Pair this buttery fish with sides that soak up the sauce. Quinoa, cauliflower rice, asparagus, broccoli, or a crisp Greek salad are natural partners. Don’t forget crusty bread for sopping up every last drop.

Baked Cod Recipe Tips

Here you’ll find 3 top tips to help you prevent your cod from turning rubbery and tough. All-too-often, this fish is overcooked and given a bad rep. Follow these simple instructions and you’ll be golden.

Master baked cod fish with these essential pointers. Even small tweaks make a big difference with this fish recipe!
Use an instant read meat thermometer. How long do I bake the cod? Cod takes roughly 15 minutes to cook, but a thermometer eliminates the guesswork. Cook until the safe internal temperature for cod, which is 145°F. If you overcook it, the cod might come out with a tough or rubbery texture.
Pat the fish fillets completely dry. If there is too much water, it ends up boiling in the oven, which then messes with the texture of the fresh fish. I usually use paper towels and toss them away.
Cook with fresh lemons. Lemons release juices that hydrate the fillets. Cod thrives on that extra moisture. Plus, that lemony flavor is so bright and fresh!
Avoid covering the fish. Covering the fish with foil while it bakes traps extra moisture inside, which then makes the fish “boil” instead of bake. Leave it uncovered!
Bake the cod at a high temperature. A short blast at 425°F delivers tender, never rubbery, fish.
Choose uniform fillets. Pieces of similar thickness cook evenly. Fold thin tail ends under to create an even thickness when needed.
Give fillets space. Crowding the dish steams the fish, so leave a bit of a gap between each piece of fish.
Use frozen cod if needed. If you have frozen cod, thaw it completely in the fridge overnight or in cold water for 15-20 minutes, then pat it dry. Never thaw with warm water.

Hot tip: If someone asks me why their cod keeps drying out in this recipe, I ask three things: did you brush it with butter, did you use lemon slices, and did you check the internal temperature while cooking? The culprit is usually one of these three!

Recipe Variations

Cod’s mild flavor soaks up any seasoning. Start with the base and then mix it up if you please. Here’s some ideas to get your creative juices flowing.

Spicy kick: Cayenne pepper, paprika, red pepper flakes, or Cajun seasoning add heat.
Mediterranean twist: Add Kalamata olives, capers, and halved cherry tomatoes to the dish before baking. Plus, any bold Mediterranean spices would kick it up a notch.
Crispy crust: Top with a mixture of Panko breadcrumbs, Parmesan, and melted butter for a golden, crispier finish.
Herby freshness: Swap garlic parsley salt for a blend of dill, basil, and chives — or try a miso-butter paste for umami depth.
Citrusy: If the lemon slices weren’t enough, drizzle fresh lemon juice on the fish after baking, too.

Try an herb butter: If you want to go all out, use an herb butter instead of unsalted butter. Make your own by mixing softened butter in a bowl with minced garlic cloves or garlic powder, black pepper, salt, paprika, and any of your favorite herbs.

Storing & Reheating Cod Leftovers

Keep flaky cod leftovers fresh and ready for later without losing that just-baked tenderness.

Refrigerator: Place cooled, room temperature cod in an airtight container and refrigerate for up to three days.
Freezer: Cool completely, wrap each fillet in plastic, then place into a freezer-safe bag. Freeze for up to two months. Thaw overnight in the fridge.
Reheating: Warm the fish gently in a 300–350°F oven until it is heated through. Add a dab of butter and a squeeze of lemon to revive the moisture.

Meal prepping? Oven baked cod takes only 5 minutes to prep, so even though it’s not a “make-ahead” dish, prep time is so quick that it doesn’t even need to be! Make it fresh for dinner one night, and then use the leftovers throughout the week. Flake cold cod over a salad, toss it into pasta, or use it in place of tuna for a quick fish-salad lunch throughout the week.
