Watch America's Best Cook

The final four contestants compete in the three remaining challenges in order to decide who is America's Best Cook. The winner will take home the grand prize.

There's only one week before the finale; five cooks remain and are given challenging ingredients including quail, octopus, and chicken livers. Guest Judge Chef Marcel Vigneron appears.

This weeks challenge is brunch and Iron Chef Geoffrey Zakarian is one of the judges.

Seven remaining cooks face the most dreaded challenge in cooking competitions -- dessert. After a knife slip, one cook is sent to the Emergency Room and faces leaving the competition altogether.

Now that the mentors have selected their teams, the real competition begins. In their first challenge, the cooks are tasked with elevating kitchen classics. Guest judge Chef Anne Burrell will decide which cooks will go to the elimination challenge, The Pressure Cooker, where they must turn a plain chicken breast into an amazing dish if they want to stay in the competition.

Sixteen of the country's best amateur cooks arrive in New York for their chance at $50,000 and the title of America's Best Cook. But first, they must compete to represent their region, in one of two spots on a Superstar Chef Mentor's team. Iron Chef Michael Symon will be choosing from the North, Iron Chef Cat Cora takes the South, Iron Chef Alex Guarnaschelli is heading up the East and Food Network star Chef Tyler Florence is representing the West. The Mentors will be choosing wisely, as they will also be out of the competition if both of their cooks are eliminated.
