While sous vide cooking ensures even cooking, resting meat after is still beneficial. A short rest of 5-10 minutes allows the meat to relax and reabsorb some juices, improving tenderness and flavor.
Sous vide cooking brings meat to a precise temperature throughout, but it doesn't necessarily replicate the effects of traditional resting after roasting or grilling. During the sous vide process, muscle fibers can still contract slightly. Resting allows these fibers to relax, which helps retain moisture.Here's a breakdown of why resting is helpful, even after sous vide:1. **Muscle Fiber Relaxation:** The gentle heat of sous vide minimizes muscle fiber contraction, but it doesn't eliminate it entirely. Resting allows the fibers to relax further, resulting in a more tender texture.2. **Juice Reabsorption:** As the meat rests, some of the juices that were expelled during cooking are reabsorbed back into the muscle fibers. This leads to a juicier and more flavorful final product.3. **Carryover Cooking:** Although minimal, there can be a slight amount of carryover cooking, especially with thicker cuts of meat. Resting allows the temperature to equalize throughout the meat.4. **Surface Drying (for searing):** If you plan to sear the meat after sous vide, a brief rest allows the surface to dry slightly, promoting a better sear.For most cuts of meat cooked sous vide, a resting period of 5-10 minutes is sufficient. Larger roasts may benefit from a slightly longer rest, up to 15 minutes.
Don't rest the meat uncovered for too long, especially in a cold environment, as it can cool down too much. If you need to rest it for longer than 15 minutes, consider tenting it loosely with foil to retain heat without steaming the surface.
