MasterChef, 8 p.m., Fox
Keep an eye this season on St. Pete native Francis Biondi, a 25-year-old who's competing for the ultimate prize on Gordon Ramsay's cooking show. Last week, Biondi's meatloaf (stuffed with cheese!) was named the best of the night; he should fly through tonight's episode on that advantage.
Remembering the Artist: Robert De Niro, Sr., 9 p.m., HBO
Did you know Robert De Niro's dad (er, Robert De Niro Sr.) was a respected artist who created abstract-expressionist paintings in the mid-20th century? Oh, come on, no you didn't. The younger De Niro recalls the elder De Niro's life and career in this hourlong documentary.
Suits, 9 p.m., USA
It's summer, which can only mean one thing: Lots of sleek, vapid USA programming! The fourth season of Suits, a.k.a. The Good Wife Lite, kicks off with "changes afoot at Pearson Specter."
So You Think You Can Dance, 8 p.m., Fox
One of our favorite guest judges, Christina Applegate, stops by for the third episode of auditions. Hey, if she can't get a network show to stick (still mourning you, Up All Night), maybe she can turn these insightful guest spots into a full-time thing.
The Sixties, 9 p.m., CNN
We could watch endless coverage of the mysterious assassination of President John F. Kennedy. Which is why this week's episode of the Tom Hanks-produced spin through the 1960s is a must-see. Alexandra Zapruder (granddaughter of the Zapruder who shot the famous film), members of the Warren Commission (which concluded that Lee Harvey Oswald acted alone in killing Kennedy) and more weigh in on what happened that tragic day.
Last Comic Standing, 10 p.m., NBC
As the semifinals begin, the lucky remaining contestants get coached by comedy masters Wanda Sykes, who's serving as executive producer this year, and Amy Schumer, one of the show's most successful alums (she placed fourth on the fifth season).
SEASON FINALE Sing Your Face Off, 9 p.m., ABC
Three weeks after it premiered, this strange competition show is already coming to an end. That's how you burn off unwanted episodes, folks. We can't quit just yet; tonight features contestants transforming into M.C. Hammer (the pants!), Madonna and Whitney Houston, plus Debbie Gibson and Darrell Hammond perform as Sonny and Cher.
