I cook for just my daughter and I as my Husband travels during the week. I always end up just cooking 3 breasts instead of 6 or I even use breast for whole chicken recipes. I think with mine I add so much liquid that don't dry out. I always add wine or soup or both. I find they come out very tender and still keep cooking time as directions...........I am not sure but the liquid really helps even broth or terriyaki......
Not sure if this helps, will be interested in what other people's suggestions are.
