Begin by gathering all your ingredients. If your cod fillets are frozen, ensure they are completely thawed. Pat them dry with paper towels to remove excess moisture.
Sprinkle salt and pepper generously over both sides of the cod fillets. This will enhance the natural flavors of the fish.
In a large skillet, melt 2 tablespoons of butter over medium heat. Allow it to become bubbly but not browned.
Once the butter is melted, add the minced garlic to the skillet. Sauté it for about 1 minute, stirring constantly until fragrant but not burnt.
Gently place the seasoned cod fillets into the skillet. Cook for about 4-5 minutes on each side, or until the fish flakes easily with a fork and is cooked through.
After the cod has cooked, reduce the heat to low and pour in 1 cup of heavy cream. Stir well to combine the cream with the garlic and butter.
Incorporate 1 teaspoon of lemon juice into the creamy mixture. This will add a refreshing zing to balance the richness of the sauce.
Sprinkle the chopped fresh parsley over the top for a burst of color and fresh flavor. Serve the cod immediately, spooning extra garlic cream sauce over the top.
