Easy to make and full of fresh flavor, this Baked Lemon Cod is the perfect weeknight dinner and it’s elegant enough for occasions too!



46 ounce cod fillets, fresh or thawed from frozen

2 tablespoons butter, ghee or olive oil

1 tablespoon olive oil

1 clove garlic, minced

1 tablespoon chopped fresh thyme, see notes

1 tablespoon chopped fresh parsley

1 teaspoon lemon zest

1/2 teaspoon sea salt, or to taste

1/4 teaspoon ground black pepper

1 lemon, sliced


Preheat the oven to 400ºF. 

Add the butter, olive oil, garlic, thyme, parsley, lemon zest, sea salt, and pepper into a small bowl. Mash the mixture together with a fork until fully combined.

Place the fish fillets in a baking dish, (I used a 9″x13″) and evenly spread the herbed butter mixture over the top. Add 4 slices of lemon on the sides or top of the fish fillets.

Bake until the fish is just done in the center and easily flakes apart with a fork on the edges, 15-20 minutes.

Serve with the remaining lemon slices.


To chop fresh thyme, first remove the leaves from the tough stems, then roughly chop them.
