Alex Guarnaschelli, as seen in “Supermarket Stakeout”

It has long been said: “If you can’t take the heat, get out of the kitchen.” Chefs – professional and homemade alike– know the idiom well, but perhaps none have proven their ability to face the flames like Alex Guarnaschelli.

An Iron Chef, frequent "Chopped" judge and executive chef at Butter, her home-base restaurant in New York City, Guarnaschelli is also at the helm of three Food Network/Cooking Channel shows that are featuring new content in the coming weeks. Needless to say, this is a busy time for chef Alex Guarnaschelli.

First, our steadfast host got her hands dirty in “Alex vs. America,” with Season 3 having premiered Sunday, April 16. In each episode, including the one airing this Sunday (April 23), Guarnaschelli joins the competition, going up against three guest chefs who specialize in their given weekly theme. The competitors complete two rounds of cooking before offering their plates to a panel of blindfolded judges — Guarnaschelli's attempt included. A winner is named, and if the best plate belongs to a guest chef, then Guarnaschelli is bested, and the champion receives both a cash prize and ultimate bragging rights, having beaten one of Food Network's best at her own game.

Guarnaschelli didn't stop there. From the frozen food aisle to authentic Italian cooking, Guarnaschelli is also taking her hosting prowess worldwide with “Ciao House," which debuted alongside the season premiere of "Alex vs. America." A new episode airs this Sunday, April 23.

And then it's back to America next week, when Guarnaschelli takes her talents to the road in the fifth season of “Supermarket Stakeout,” premiering Monday, May 1, on Cooking Channel Canada. Guarnaschelli decorates supermarket parking lots with pop-up kitchens, giving four chefs each a $500 budget as they bargain with unsuspecting grocery shoppers for the ingredients necessary to complete their challenge, taken straight from the basket of a total stranger. Chefs ambush real-life customers, negociating for grocery bags and whatever mystery items might be inside, then using what they find to cook full-fledged meals for weekly guest judges.

From America to Italia, Guarnaschelli is determined to get a taste of talent wherever she goes. Stay tuned in to Food Network and Cooking Channel Canada to see what the chef cooks up next.
