The eliminated mentor returns to serve as the final guest professor, testing the cooks on their history with food. In the first round, the mentors must make an updated version of meatloaf to win an advantage for their cooks in the next round. Then, the home cooks revisit their first challenge cooking with lunch box ingredients, and in the final round, the two remaining cooks must create the best dish of their lives to win the $50,000 prize!
