Preheat your oven to 400°F (200°C).
In a saucepan over medium heat, melt the butter. Add the minced garlic and sauté for about 1 minute until fragrant.
Stir in the heavy cream and bring to a simmer. Reduce the heat to low and mix in the Parmesan cheese until smooth. Season with lemon juice, salt, and pepper to taste.
Place the cod fillets in a baking dish. Pour the Parmesan cream sauce over the fillets, ensuring they are well coated.
Bake in the preheated oven for 15-20 minutes, or until the cod is cooked through and flakes easily with a fork.
Garnish with fresh parsley before serving. Enjoy your meal!
