The idea that searing meat "seals in" its juices is a persistent culinary myth that does not hold up under scientific scrutiny. Food scientists have tested this claim repeatedly, often by weighing cuts of meat before and after cooking. The results consistently show that seared meat loses roughly the same amount of moisture, and in some cases even more, than meat cooked without searing. If searing truly created a moisture-proof barrier, seared meat would retain significantly more weight and juiciness than unseared meat, but this is not what happens.

The physical reasoning behind this is straightforward. Searing occurs when meat is exposed to high heat, triggering the Maillard reaction, a chemical process that creates browning and complex, savory flavors. However, this browning does not form a waterproof seal. Meat is composed of muscle fibers and water, and as it cooks, heat causes proteins to contract and squeeze out moisture regardless of whether the surface has been seared. In fact, the high temperatures required for searing can accelerate moisture loss near the surface of the meat.

The persistence of this myth likely stems from the genuine improvements searing does provide: enhanced flavor, appealing color, and better texture through browning. These real benefits are often mistakenly attributed to moisture retention. Culinary experts now generally agree that searing should be valued for its flavor-enhancing qualities rather than any supposed ability to lock in juices, and that proper cooking temperature and resting time play a much larger role in retaining moisture.
