Boil the Fish: In a large pot, bring water to a boil with a pinch of salt. Add the fish fillets and cook for 5-7 minutes, or until the fish is opaque and flakes easily with a fork. Drain the fish and set it aside on a serving plate.
Make the Sauce: In a medium saucepan, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute. Stir in the lemon juice, salt, pepper, and paprika. For a creamier sauce, add the heavy cream and simmer for an additional 2-3 minutes. Stir in the chopped parsley just before serving.
Serve: Pour the garlic butter sauce over the cooked fish fillets. Garnish with extra parsley or a sprinkle of paprika if desired. Serve immediately with your choice of sides, such as mashed potatoes or steamed vegetables.
