This Guinness Mac & Cheese is ultra-creamy and infused with the deep, roasted flavor of Ireland’s favorite stout. Made with sharp Irish cheddar, cream cheese, garlic, Dijon mustard, and a generous splash of Guinness, it delivers rich pub-style comfort in every bite. Serve it stovetop or baked with a golden breadcrumb crust. Perfect for St. Patrick’s Day dinners, cozy comfort food nights, or a bold upgrade to your usual mac. Add bacon, mushrooms, or herbs for even more depth.
