In this garlic shrimp spaghetti recipe, succulent shrimp are tossed in a rich and creamy garlic butter sauce and placed on a bed of spaghetti noodles. It feels like a gourmet Italian meal, but it's easy enough for busy weeknights. It's a protein-rich meal that's ready in less than 30 minutes, and it can even be customized for dairy-free or gluten-free folks.
