24 in 24: Last Chef Standing

In the first shift, the chefs endure three challenges testing speed to impress judge Antonia Lofaso.

Michael Symon and Esther Choi begin the second shift with two chefs in a head-to-head elimination that tests simplicity; the 12 remaining chefs face a tricky taste test from judge Graham Elliot.

In a shift that tests resourcefulness, Michael Symon and Esther Choi ask the 11 remaining chefs to create a three-course meal worthy of a black-tie event in 60 minutes; judge Jet Tila decides which chef will be clocking out.

At hour 10, fatigue has officially set in for the 10 remaining chefs, but there's no rest for the weary as they face their most creatively demanding challenges yet. First, co-hosts Michael Symon and Esther Choi give the chefs a mere 10 minutes to turn any available produce into a beautiful plate of food that will be judged not by taste but by appearance. Then, the chefs are assigned famous works of art which they must use for inspiration. Judge Fariyal Abdullahi decides which plates of food taste the best and which plates of food look most impressive, and the chef who does the poorest job will have to clock out.

Hour 13 of this extreme culinary competition features unrelenting twists and turns for the exhausted chefs. First, co-hosts Michael Symon and Esther Choi challenge the nine remaining competitors to turn snacks they find in the breakroom into dessert. Then, after being given only two minutes to shop for a lumberjack breakfast, the chefs must turn their breakfast ingredients into a different meal entirely for judge Brooke Williamson. And that's just the beginning!

Frustration and fatigue mounts in hour 16 as co-hosts Michael Symon and Esther Choi ask the eight remaining chefs to work in teams to make a soup and sandwich, all while handling three culinary curveballs that threaten to ruin their chances at survival. After the first challenge, one team is safe while the other team is left to keep on battling. Judges Carlos Anthony and Brian Malarkey decide who will move on to shift seven.

The chefs are tired and grumpy as shift number seven begins, but they're more determined than ever to get to the final shift and have a chance at winning $75,000. Co-hosts Michael Symon and Esther Choi present the first challenge, which features a three-way battle in spicy street food. Next, it's math time as the chefs must do some measurement calculations after being up for 19 hours! Then, the competitors make a finale-worthy fish dish for judge Andrew Zimmern to earn a spot in the final shift.

In the final shift, Michael Symon and Esther Choi give the five remaining chefs a familiar challenge before asking them to create an elevated breakfast, lunch and dinner for judges Antonia Lofaso, Graham Elliot and Jet Tila.

After more than 20 nonstop hours, Michael Symon and Esther Choi ask the final chefs to create an elevated lunch and dinner; judges Antonia Lofaso, Graham Elliot and Jet Tila decide who will win $75,000 and the title of "Last Chef Standing."
