The sous vide technique preserves the natural moisture and flavor of meat primarily through its vacuum-sealed, low-temperature cooking process.12

By placing food in an airtight, vacuum-sealed pouch, the meat is cooked in its own juices. Because the food is submerged in water heated to a precise, low temperature—typically below simmering—it cooks consistently throughout without the moisture loss often associated with high-heat methods like grilling or pan-searing. This controlled environment ensures that the meat retains its internal juices and aromas, resulting in enhanced tenderness and flavor.12

To ensure safety, it is important to follow proper food handling practices, such as chilling food below the danger zone before cooking or searing the surface of the meat to eliminate bacteria.1
