Starting Sunday, Aug. 23 at 8|7c, famed chefs will enter Flavortown Market for a special five-part All-Stars series of Guy's Grocery Games. You never know what host Guy Fieri has up his sleeves as he doles out games that even these chefs will find challenging. Whether it's the Fieri Food Pyramid, a game of Can Can or the dreaded Food Wheel, they must be prepared for anything. The rotating panel of judges comprises Richard Blais, Melissa d’Arabian, Duskie Estes, G. Garvin, Troy Johnson, Beau MacMillan, Brian Malarkey, Catherine McCord and Aarti Sequeira. In the fifth and final episode, the All-Stars will be teamed up with professional athletes, giving the All-Stars even more of a sporting chance to win a cash prize for their respective charities!

Flavortown Flips Over the Judges! — Sunday, Aug. 23 at 8|7c

Guy turns the tables on the show's All-Star judges by making Richard Blais, G. Garvin, Beau MacMillan and Aarti Sequeira compete in the kitchen! First they must eat their words and prepare an international lunch using items that begin with only the letters P and Z! Then they must prepare a decadent dinner using ingredients from only the produce aisle. The two finalists must prepare a family meal that includes three strange ingredients from the Fieri Food Pyramid.

Judges: Duskie Estes, Troy Johnson, Catherine McCord

All-Stars and A-Lister Dinners — Sunday, Aug. 30 at 8|7c

Culinary titans Anne Burrell, Eric Greenspan, Jet Tila and Marcel Vigneron are not spared Guy's twists when a bowling game selects some strikingly bizarre ingredients for a hearty lunch. Next the chefs have to think outside the boxed foods and each make their best dish using processed items from the middle aisles of the store. Then the chefs experience real highs and lows when the feared Food Wheel determines the high-end and low-end ingredients in their A-list dinners.

Judges: Duskie Estes, Troy Johnson, Brian Malarkey

Four world-class chefs, Ron Ben-Israel, Penny Davidi, Pat Neely and Justin Warner, compete to win up to $20,000 for charity. First the chefs must make their favorite lunch using a ridiculous Red Light Special. Next they'll have to rummage through the Clearance Carts to make their best noodle dish. The two finalists must each make a showstopping dinner using the four uncanny ingredients from the Fieri Food Pyramid.

Judges: Melissa d’Arabian, Duskie Estes, G. Garvin

All-Stars in the Aisles — Sunday, Sept. 13 at 8|7c

Guy pulls no punches when he challenges superstar chefs Madison Cowan, Elizabeth Falkner, Aaron McCargo Jr. and Michael Psilakis to make an upscale dinner using the double whammy of frozen and canned foods. Next it’s time for multiple cart swaps in a weekend brunch edition of Musical Carts. Then the remaining two All-Stars must turn a kernel of an idea into their best dish using one ingredient, i.e., corn, in two different ways, with ingredients from three aisles.

All-Stars Team Up with Pro Athletes — Sunday, Sept. 20 at 8|7c

Four professional athletes pair up with celebrity chefs — Rich Aurilia with Robert Irvine, Marcel Reece with Brian Malarkey, Jennifer Lacy with Marc Murphy, and Takeo Spikes with Lorena Garcia — for one of the biggest All-Star lineups Guy’s Grocery Games has ever seen! These dynamic duos are challenged to make a winner’s dinner using only seven items after going through the Express Lane. Next a toss of the dice will determine what these pairs must use for their pregame meal. Then teams will race the store relay style, grabbing only one ingredient at a time, to create their best cheat day dish. The winning team will get the chance to sprint through the aisles for up to $30,000 for charity!

Judges: Troy Johnson, Beau MacMillan, Aarti Sequeira
