Part 1 of 2. The Top 4 chefs—Krissi Biasiello, Natasha Crnjac, Jessie Lysiak and Luca Manfe—compete in a mystery-box challenge that requires them to prepare a three-course meal using regional ingredients from various areas of the U.S. The losing team participates in a pressure test, after which one contestant is eliminated.
Contestants that were ousted earlier in the season get a chance to earn their spot back. First, they must cook as many fried eggs as possible, and the Top 2 chefs from that test advance to a blind-taste-test challenge involving salmon, with the winner getting to rejoin the competition.
The Top 8 chefs are taken to a remote field for an overnight challenge in which they must cook for sustenance and create lunch for the judges using limited ingredients. Later, the losing team competes in a spun-sugar-dessert pressure test.
Part 1 of 2. Home cooks representing 26 states arrive in Los Angeles to compete for the title of MasterChef and the $250,000 grand prize in the Season 4 premiere. Each hopeful prepares a signature dish and presents it to judges Gordon Ramsay, Joe Bastianich and Graham Elliot, who rate on flavor, creativity and presentation.
