Garlic butter baked cod is the kind of dinner I reach for when the evening is busy but I still want to put something truly satisfying on the table. I have been making this recipe for years, and the moment that buttery, garlicky aroma drifts out of the oven, everyone in the house comes running.
I grew up watching my mother cook fish on Friday nights in our little Midwest farmhouse kitchen. She would melt butter in a small saucepan, mince fresh garlic until her hands smelled wonderful, and hum softly while she worked. There was nothing fancy about it, just real ingredients handled with care. That is the spirit I bring to this garlic butter baked cod. Flaky white fish wrapped in a golden, herb-flecked butter that crisps slightly at the edges while staying moist and tender at the center. It feels like a Sunday dinner, even on a Wednesday night. Your kitchen is about to smell incredible.

Key Players in This Recipe
Good baked cod starts with understanding what each ingredient brings to the dish. Here is what goes into this garlic butter baked cod and why every element earns its place.
Cod (1 lb, four 4 oz. filets): Mild, slightly sweet, and beautifully flaky, cod is the ideal canvas for bold flavors like garlic and butter. I always look for filets of even thickness so they bake at the same rate. Frozen cod works wonderfully, just thaw it properly and pat it dry before using.
Butter (4 tablespoons, room temperature): This is the heart of the dish. Room temperature butter blends smoothly with the oil and garlic into a spreadable paste that coats every inch of the fish. In my kitchen, I prefer unsalted butter so I can control the seasoning myself.
Olive oil (2 tablespoons): A splash of olive oil helps the butter spread more easily and slows any browning in the oven, keeping the fish moist rather than drying out. It also adds a subtle richness of its own.
Fresh garlic (4 cloves, minced): The star of the show. I always reach for fresh garlic here, it delivers a punch of flavor that garlic powder simply cannot match. Mince it fine so it integrates into the butter paste beautifully.
Paprika (1/4 teaspoon): Just a touch of paprika adds a warm, golden color and a very gentle smokiness that makes the finished dish look as good as it tastes. I use sweet paprika to keep things mild and approachable for the whole family.
Salt (1/4 teaspoon): A small amount goes a long way here. Salt sharpens every other flavor in the dish, especially the garlic and lemon.
Fresh parsley (2 tablespoons, finely chopped): Parsley adds freshness and a pop of green color that makes the plated dish look really lovely. If you are out of fresh, 1 teaspoon of dried parsley makes a perfectly fine substitute.
Lemon (1 fresh): Half gets sliced and baked right on top of the fish, infusing a gentle citrus brightness as it roasts. The other half I cut into wedges for serving, so everyone can add a squeeze of fresh juice to taste.
How to Make Garlic Butter Baked Cod
I have made this garlic butter baked cod enough times that the steps feel natural. Follow along and you will have dinner on the table in no time.
- Preheat your oven to 400 degrees F. Betty always starts by getting the oven fully hot before anything else. A fully preheated oven means even cooking from the moment the fish goes in.
- Make the garlic butter paste. In a small bowl, combine the room temperature butter, olive oil, minced garlic, paprika, salt, and chopped parsley. Stir until it forms a fairly smooth, spreadable paste. A few small lumps of butter are perfectly fine.
- Coat the cod filets. Place your cod filets in a baking dish and spoon the garlic butter mixture over each piece. Spread it evenly so every inch of the fish is coated. I have learned that a generous, even layer is the key to consistently flavorful results.
- Add the lemon. Slice half the lemon into thin rounds and lay them across the tops of the filets. Cut the remaining half into wedges and set aside for serving.
- Bake for 15 to 20 minutes. Bake until the cod flakes easily with a fork and the internal temperature reads 145 degrees F. Thicker filets in a heavy ceramic or glass dish need the full 20 minutes, while thinner pieces in a metal pan are often done by 15 minutes.
- Baste and serve immediately. Spoon the buttery, garlicky pan juices over the top of the fish before plating. This step adds an extra layer of flavor that my family notices every single time. Serve right away with the reserved lemon wedges on the side.
Tips for the Best Results
- Use room temperature butter so the mixture spreads easily onto the fish
- Fresh garlic delivers the best flavor; avoid garlic powder if you can
- Always spoon pan juices over the fish before serving for extra flavor
- Dried parsley (1 tsp) can substitute for fresh parsley in a pinch
- Pat frozen cod completely dry before applying the butter mixture so it sticks properly
- Use an instant-read thermometer to avoid overcooking; cod turns rubbery quickly past 145 degrees F
Keeping This Baked Cod Fresh
I typically store any leftover garlic butter baked cod in a shallow airtight container in the refrigerator, where it keeps well for up to 3 to 4 days. Fish is best eaten fresh, but leftovers work great the next day. I often flake cold cod over a salad for lunch and it is delicious.
Freezing cooked cod is possible but not something I do often with this recipe. The texture can turn slightly watery after thawing. If you do freeze it, wrap individual portions tightly in plastic wrap, then seal in a freezer bag for up to one month. Thaw overnight in the refrigerator before reheating.
For reheating, I strongly recommend a low oven at 275 degrees F for about 10 minutes rather than the microwave. This preserves the flaky texture and keeps the fish from becoming rubbery. A quick splash of fresh lemon juice before reheating helps revive the brightness of the dish.

FAQs
Yes, frozen cod works beautifully here. Thaw it quickly by placing the vacuum-sealed bag in a bowl of cold water for 10 to 15 minutes, then pat the filets very dry before adding the butter mixture. Excess moisture can prevent the butter from adhering properly to the fish.
The best method is using an instant-read thermometer. The fish is done when the thickest part reaches 145 degrees F. Visually, the flesh will turn from translucent to opaque white and will flake easily when pressed with a fork.
Pull the fish out of the oven as soon as it hits 145 degrees F internally. Cod gets rubbery when overcooked, and the residual heat from the baking dish will continue cooking it for a minute or two after you remove it from the oven.
