Kelly Clarkson drops into the 'Top Chef' kitchen for a Quickfire based on her new movie, "Trolls: World Tour," where the chefs are tasked with combining colorful ingredients from six different musical lands to make one delicious dish.

The first elimination challenge takes the Chefs to the beach to cook a seafood meal - however, their only heat source will be fire.

The final five travel to Italy, where the chefs must make an aperitivo for 30 locals from the town of Lucca that pairs perfectly with a Peroni beer. Then, they hunt the elusive white truffle which they must use in a dish for a Tuscan food festival.

The final three all stars face off in an epic Italian showdown to cook the meal of their lives.
