Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 400°F (200°C).

Lightly grease a baking dish or line it with parchment paper for easier cleanup.

Step 2: Make the Garlic Butter Sauce

In a small saucepan over medium heat, melt the butter.

Add the minced garlic.

Cook for about 1 minute, stirring constantly until fragrant.

Stir in:

Fresh lemon juice
Lemon zest
Red pepper flakes (if using)

Mix well and remove from the heat.

Step 3: Arrange the Cod

Pat the cod fillets dry with paper towels.

Arrange them in a single layer in the prepared baking dish.

Pour the warm lemon garlic butter evenly over each fillet.

Step 4: Bake

Bake for 12–15 minutes, depending on the thickness of the fish.

The cod is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Avoid overcooking to keep the fish moist and tender.

Step 5: Garnish and Serve

Sprinkle the baked cod with freshly chopped parsley.

Serve immediately with extra lemon wedges for squeezing over the top.
