The proof that there will be another season is on the Food Network's website. If you look at the episode guide for Southern at Heart, you see that there is a season 2 listed (pictured below). No specific episodes are listed yet because the Food Network schedule is only updated through February right now.
Pretty much all of the recent winners of Food Network Star have had their show renewed for at least a 2nd season, with the exception being Justin Warner, who only got a 1-hour special.
