How Long Can I Store Seasoned, Vacuum Sealed Chicken
Since you're cooking by sous-vide anyway, why don't you put the vacuum sealed, seasoned chicken breasts in the freezer? You just put the still frozen packs into the circulator a half-hour or 45 minutes sooner. Then you will always have a no-muss no-fuss dinner at the ready.

Here's a YouTube video of exactly that.

Season differently and vacuum seal several family packs at once! Save money and hassle.

For frozen boneless chicken breasts, figure 141F to 148F (60.5C to 63.9) for 2+ hours, longer for bigger pieces. (I like 147F)

You can do the same thing with steak, don't raise the temperature, just add some time at your preferred temperature.
