Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the fish

• 4 cod fillets (about 5–6 ounces each)

• Salt, to taste

• Black pepper, to taste

For the lemon garlic butter sauce

• 4 tablespoons unsalted butter, melted

• 1 tablespoon olive oil

• 3 garlic cloves, minced

• 2 tablespoons fresh lemon juice

• 1 teaspoon lemon zest (optional)

• 1 tablespoon chopped fresh parsley (optional, for garnish)

Directions

1. Preheat your oven to 400°F (200°C). Lightly grease a baking dish large enough to hold the cod in a single layer.

2. Pat the cod fillets dry with paper towels to remove excess moisture. Season both sides with salt and black pepper.

3. In a small bowl, whisk together the melted butter, olive oil, minced garlic, lemon juice, and lemon zest if using.

4. Place the seasoned cod fillets in the prepared baking dish. Pour half of the butter mixture evenly over the fish.

5. Bake for 12 to 15 minutes, depending on the thickness of the fillets. Halfway through cooking, spoon the remaining butter sauce over the cod to keep it moist and flavorful.

6. The fish is done when it turns opaque and flakes easily with a fork, or when it reaches an internal temperature of 145°F (63°C).

7. Remove from the oven and sprinkle with fresh parsley before serving, if desired.

Variations

Add herbs: Fresh dill, thyme, or basil can be stirred into the butter sauce for added flavor.
Make it spicy: Add a pinch of red pepper flakes to the sauce for gentle heat.
Add vegetables: Include cherry tomatoes, asparagus, or zucchini in the baking dish for a complete one-pan meal.

Creamy option: Stir a tablespoon of heavy cream into the butter sauce for extra richness.

Storage/Reheating

Store leftover cod in an airtight container in the refrigerator for up to 3 days.

To reheat, place the fish in a baking dish, spoon a little extra butter or lemon juice over the top, and warm in a 350°F (175°C) oven for about 8–10 minutes until heated through. Reheat gently to avoid drying out the fish.

Freezing is not recommended after cooking, as the texture may become dry once thawed.

Can I add cheese on top?
