Ingredients & Variations

We love garlic butter on everything from roast chicken to this easy fish recipe.

FISH: Fresh or frozen cod is easy to find and affordable. We love cod loins in this recipe as they’re a bit thicker but cod filets are great too.

Other white fishes to use are tilapia, haddock, hake, or sea bass.

SEASONINGS: We prefer melted butter over olive oil in this recipe for its flavor. Garlic adds a savory flavor to baked cod and lemon pepper gives it a bright flavor along with the lemon juice.

Use fresh lemon juice, you’ll need a lemon for slices as well so one whole lemon should do it!

Use a little bit of lemon zest from the lemon to make homemade lemon pepper if you’d like! We prefer homemade as I find store-bought lemon pepper a bit too salty!

VARIATIONS: For a crispy topping, add seasonings to some homemade breadcrumbs, crushed crackers, or Panko.

PRO TIP: Always thaw frozen fish in the refrigerator, not on the counter.

How to Bake Cod

This baked cod recipe is simple to make.

  1. Prepare lemon slices for the baking dish & squeeze enough juice to equal 1 tablespoon.
  2. Season cod fillets with lemon pepper & place them on lemon slices.
  3. Drizzle with garlic butter. Bake at 400 degrees F until flesh is opaque and it flakes easily.

PRO TIP: Use a cake tester or fork to lightly test for doneness.

Tips for the Best Fish Fillets

Be sure to dab the cod dry after it thaws in the fridge as frozen filets will release a bit of water.

The key to perfectly flaky and tender fish fillets is to avoid overbaking them. Fish will continue to cook once it’s been removed from the oven.

Serve Baked Cod With…

It goes well with a light tossed salad, rice pilaf or brown rice, and either asparagus or broccoli.

This fish is great served with a glass of pinot grigio or other crisp white wines.

How to Store Leftovers

Keep leftover baked cod fillets in a covered container in the refrigerator for up to 3 days. Add to omelets, soups, or stews. Reheat in a saucepan with a little water and cover until steamed through.

Lemon Garlic Butter Baked Cod

Tender, flaky, and infused with lemony garlic butter, this baked cod is bursting with flavor in every bite!
Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes
Servings 4


  • 1 lemon
  • ¼ cup unsalted butter melted
  • 1 clove garlic minced, or ¼ teaspoon garlic powder
  • 1 teaspoon lemon pepper
  • ½ teaspoon dried dill weed
  • 4 cod loins or filets, 4-5 oz each
  • 1 tablespoon fresh parsley chopped


  • Preheat oven to 400°F.
  • Slice half of the lemon. Juice the other half, you will need 1 tablespoon of lemon juice. Lay lemon slices in a casserole dish.
  • Whisk together butter, garlic, and 1 tablespoon of lemon juice.
  • Pat cod filets or loins dry with a paper towel. Sprinkle cod with lemon pepper & dill weed and place over lemon slices.
  • Pour garlic butter mixture over the cod. Bake 15-20 minutes or just until opaque and the fish flakes easily. Do not overcook.
  • Sprinkle parsley over top and spoon butter over to serve.


Store bought lemon pepper is usually quite salty so I don't find the need to add much salt to this recipe. Taste the lemon pepper and if it isn't salty, a little bit of additional salt can be added to the recipe.  
The cooking time can vary based on the shape and thickness of the fish. Cod that is 1 to 1 1/2 inches thick will need 15-20 minutes while thinner filets will need a bit less time. Check the cod early to make sure it doesn't overcook.
If you'd like extra butter (to drizzle on rice or vegetables) the butter portion of the recipe can be increased.
Cod should reach an internal temperature of 145°F. It will be opaque and flake easily once cooked.
Once cooked, remove the cod from the baking dish as the heat from the dish will continue to cook the cod.

  1. This is a tasty way to bake cod. Turned out great and as long as you watch your timing and thickness of the portions, this is fool-proof, affordable and very tasty.5 stars

  2. This was delicious!!! Quick and easy. I doubled the butter sauce since I had 7 loins. I also added lemon zest, capers and used fresh dill instead of parsley. I paired it with sautéed zucchini, summer squash, tomatoes, and sweet onions. It made a nice low carb/ calorie dinner.
    Thanks so much for this recipe!!!! It is now my go to!!!!
    Kim L.5 stars

  3. This was absolutely delicious. Thank you so much. I will be definitely be making this again and again.5 stars

  4. Made this the other night. I’m not a huge fish fan, but this recipe was really good! Super easy and quick. I used a thick filet and baked it 30 minutes and finished under the broiler. Will make again. Thanks for the great recipe!5 stars

  5. Great recipe! Cod can be boring, but not this!
    I had bought fresh cod this morning from the fish vendor at the market not knowing I would be entertaining for 6 tonight. Found this recipe and -oh wow – it turned out to be awesome! Tons of flavor! Thank you!5 stars

    1. Hi Mary, I would check with the store you are purchasing from. Cod do have bones in them but you can purchase boneless fillets. Hope that helps.

  6. Parsley is a good herb substitute. The recipe made me laughing. When did fish have loins ? Fish are cut into fillets.

    1. Hi Dennis, it is possible to purchase a cod loin. They are shorter and fatter cuts compared to a cod fillet. Hope that helps!
