Everyone’s favorite reality cooking show — I said “cooking,” so “The Great British Baking Show” doesn’t count! — returns March 19 with an all-star cast. Bravo’s “Top Chef” is returning for its 17th season, taking place in Los Angeles and with a cast of cheftestants who devotees will recognize from previous years. While Colorado isn’t getting too much love this season, fans should recognize one contestant from Season 15, which took place around the Centennial State: Joe Sasto, based in L.A., returns for Season 17. And Gregory Gourdet, the “Top Chef” Season 12 runner-up, makes a comeback this year.
