Sixteen of the country's finest junior home cooks compete for eight of the Top 20 spots on this season's MASTERCHEF. After being split into four groups, each with a distinct signature dish, the kids get started. Only two contestants from each group will find out if they will succeed in moving on to the next round of challenges.

Celebrity chef Aarón Sánchez steps into the MASTERCHEF kitchen as a guest judge. The Top 20 young chefs will face their first mystery box challenge of the season, during which they will have to put their own spin on the most commonly eaten crop in the world – rice. Later in the kitchen, Chef Gordon Ramsay teaches the kids how to make his signature hand-roasted sea bass, which they must replicate.
