Amateur chefs compete in a series of cooking challenges overseen by a panel of accomplished chefs. Each week they have to survive elimination and become a culinary master, earning the title of MasterChef.
In the first round of auditions, chefs from the Northeast prepare their signature dishes for judges Gordon Ramsay, Aaron Sanchez, Joe Bastianich and Daphne Oz.
As chefs from the Midwest battle it out for a coveted spot in the top 20, each contestant has 45 minutes to prepare a signature dish that impresses the judges.
Chefs from the West are the next up in the regional auditions as they prepare their signature dishes for a panel of all-star judges.
Regional auditions conclude with signature dishes presented by chefs from the South hoping to secure the five remaining spots in the top 20.
The top 20 home chefs enter the kitchen, and each contestant must create a state fair-inspired dish - but whoever wins the challenge grants the rest of their region immunity.
The chefs have their first Mystery Box Challenge - apples! With sweet and savoury flavours on the table, the chef with immunity must assign each region one kind of dish to cook.
The chefs face their first team challenge and must pair up with another region to grill a delicious meal for 101 firefighters and emergency personnel.

The chefs face their hardest challenge yet in this scrumptious celebration of MasterChef's 250th episode, as each contestant is assigned an iconic cake to recreate.
The contestants split into two teams to prepare lunch for over 100 kids at Dodger Stadium, and the chef with immunity must pick one member from each team to swap sides.
The Mystery Box is back - and it's every chef for themselves! The contestants must individually prepare a gourmet meal out of army rations.
The chefs tackle a classic MasterChef test: the tag-team challenge. They must take turns preparing a three-course meal, ensuring they're on the same page every step of the way.
The chefs face their toughest Mystery Box challenge yet - fish! Plus, when the chefs with immunity switch up the other contestants' fish, the competition starts to fire up.
The contestants cater to the average sports fan, while using elements from their region to elevate their dish. Plus, the chef with immunity must give a penalty to a fellow cook.
