Do you love garlic bread as much I as do? Then you’re going to LOVE this Easy Garlic Butter Baked Cod recipe. I used the same buttery garlic spread that I use for my garlic bread to top these tender and mild cod fillets. I added a little lemon for brightness and the end result is a super simple weeknight main dish that I can make on a moment’s notice.

The mild, slightly rich flavor of cod is the perfect base for the zesty fresh garlic and creamy butter. And as if this Garlic Butter Baked Cod wasn’t already perfect, it also happens to be incredibly fast and easy to make. Weeknight dinner perfection!

What’s In Garlic Butter Baked Cod

For this recipe, I took my basic Garlic Bread recipe and changed it up ever so slightly to make it more fish-friendly. Here’s what you’ll need to make this easy baked cod:

  • Cod: Frozen cod is usually the most economical option, and it thaws quickly so you can make this dinner without any forethought! Try to get fillets that are about 4oz. each.
  • Butter: This is the vehicle for all that good garlicky flavor! The richness of the butter pairs wonderfully with the light and flakey texture of the cod.
  • Olive Oil: A little oil helps make the butter mixture more spreadable, and slows the browning just a bit.
  • Fresh Garlic: The star of the show! Fresh garlic brings big punchy flavor to the fish.
  • Paprika & Salt: A little seasoning is all you need here because we want to keep the flavors light, fresh, and simple. Paprika also helps add color to an otherwise pale palate.
  • Fresh Parsley: Parsley adds a little freshness and color to this dish, which is always welcome, but it won’t be a deal breaker if you don’t have any. You can also use one teaspoon of dried parsley in place of the fresh.

How to Thaw Frozen Cod

Frozen cod is not only convenient, but you can usually get a better price than buying fresh. Frozen cod is usually sold in bags that have individually vacuum-sealed pieces, which makes thawing super fast and easy. Here is how to thaw frozen cod:

  1. Place vacuum-sealed fish in a bowl of cold water. If your fish is not vacuum sealed, place it in a tightly-closed zip top bag with as much as squeezed out as possible.
  2. Leave the fish in the cold water for 10-15 minutes, or until thawed. The total time will depend on the thickness of the fillet. Once thawed, transfer to the refrigerator until ready to use.

How to Know When Cod is Done Baking

The time needed to bake your cod will depend on the thickness of the filet and the type of baking dish you use, but cod should be baked until it reaches an internal temperature of 145ºF. At this temperature, the flesh will be opaque and will flake easily with a fork. If you continue baking too long past this point the cod can get tough or rubbery.

My filets were a little on the thick side and I used a thick ceramic baking dish that takes a little longer to heat, so I baked them for about 20 minutes at 400ºF to reach an internal temperature of 145ºF. If you have thin filets or are using a thinner metal baking dish, it may only take 15 minutes of baking. A simple electronic instant-read meat thermometer is really helpful for determining when the fish is finished baking.

Ingredients for garlic butter in a bowl, not mixed.

Preheat the oven to 400ºF. In a small bowl, combine 4 Tbsp room temperature butter, 2 Tbsp olive oil, 4 minced cloves of garlic, ¼ tsp paprika, ¼ tsp salt, and about 2 Tbsp of finely chopped fresh parsley. Mix the ingredients together until they are fairly smooth (a few small lumps of butter are okay).

Bake the Garlic Butter Cod for 15-20 minutes, or until it flakes easily with a fork and reaches an internal temperature of 145ºF. If you’re using a thin metal baking dish or have thin filets, the fish will cook faster. If you are using a thick glass or ceramic baking dish or have thicker filets (as I did here), the fish will take slightly longer to bake. Spoon any of the juices in the pan over the fish (that will spread the lemony flavor).

  1. Really yummy, easy, and quick! Winco sells individual frozen cod portions for $5-6 a piece so I’ll definitely repeat this. Another way to get fish into our diet during the week! We paired ours with roasted potatoes and green beans.
