The Half Slab of Ribs at Portillo’s is succulent, slow-cooked baby back pig ribs that are covered in a thick, smokey barbecue sauce. These ribs are cooked slowly and at a low temperature to keep their flavor and juiciness. They have the perfect mix of sweet, salty, and smokey flavors. This serving is great for BBQ enthusiasts and may be eaten on its own or with typical sides.
