This Creamy Lemon Spinach Tagliatelle is a bright, zesty twist on a comforting classic. Garlic butter and sautéed spinach lay the foundation for a rich cream sauce, balanced by the fresh acidity of lemon juice. Freshly grated Parmesan adds savory depth, while a splash of pasta water brings the entire sauce together in silky harmony. Quick, flavorful, and irresistibly creamy, this dish turns a handful of ingredients into something truly special.
