**Simple Summary: This review explores new options for the male offspring of dairy cows and whether they might have the potential to produce high-quality beef that meets the standards of the Certified Angus Beef\({}^{\copyright}\) brand. This brand is known for its quality and is sold in leading restaurants and fast-food chains. Traditionally, the offspring of dairy cows were not considered capable of producing good quality beef, mainly because of their selection for dairy type and not meat production. However, Angus terminal sires can be developed to mate with dairy cows, and if these terminal sires carry 'double-muscling' genetics, they can produce progeny with the correct muscle size and shape, while also having good marbling, tenderness, and flavour. This potentially meets the requirements to be considered Certified Angus Beef\({}^{\copyright}\). This could be a more feed and greenhouse gas (GHG) efficient approach to producing beef, as it would make better use of cattle that might otherwise be disposed for little gain.**  
In response to the increasing global demand for sustainable beef production, this review of the literature was undertaken to explore the possibility of using the progeny of cows in the pasture-based New Zealand dairy production system that are mainly of the Holstein-Friesian, Jersey, and Holstein-Friesian \(\times\) Jersey-cross breeds, to produce beef that meets the standards demanded by the Certified Angus Beef\({}^{\copyright}\) (CAB) standard. CAB is a United States of America (USA) benchmark for beef quality. Traditionally, the offspring of dairy breeds have not been suitable for producing high-quality beef due to their genetic makeup and physical characteristics. However, in the USA, breeding programmes have used genetic strategies to boost muscle meat yield in terminal-sire breeds like the Lim-Flex\({}^{\copyright}\) and NuFra Genetics\({}^{\copyright}\) T14 cattle lines. In these lines, selection has focused on enhancing musceling and other Angus traits, including ensuring the cattle are homozygous polled and black-coloured. The overall aim has been to alter the phenotypic characteristics of the offspring of dairy cows by terminal-sire crosses, so they resemble the phenotype of purebred Angus cattle and meet the CAB standard. The approach can involve using different alleles of the myostatin gene (_MSTN_) carried by the terminal Angus sires to increase carcass value from the dairy cow-derived male progeny (including the _MSTN_ c821(del11) allele or the myostatin protein p.P94L leucine-containing allele) to increase meat yield and eating characteristics. It is concluded that a targeted selection and mating strategy could provide another source of high-quality beef production, and one that also meets societal demands for better animal welfare and increased sustainability.**
