ingredients to make Lemon Garlic Butter Baked Cod

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 Ask for 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 Enjoy! 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.

Print Recipe


  • 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 Require 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.

Recipe Notes

Store bought lemon pepper is usually quite salty so I don’t find the Require 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 Carry on to cook the cod.
