"Know Your Onions" is the second episode of the seventh season of the American television series Agents of S.H.I.E.L.D. Based on the Marvel Comics organization S.H.I.E.L.D., it follows a Life Model Decoy of Phil Coulson and his team of S.H.I.E.L.D. agents as they race to stop the Chronicoms from unraveling history in 1931. It is set in the Marvel Cinematic Universe (MCU) and acknowledges the franchise's films. The episode was written by Craig Titley and directed by Eric Laneuville.
Clark Gregg reprises his role as Coulson from the film series, starring alongside Ming-Na Wen, Chloe Bennet, Elizabeth Henstridge, Henry Simmons, Natalia Cordova-Buckley, and Jeff Ward. The episode continues the 1930s setting of the season premiere with guest stars Patton Oswalt and Darren Barnet also returning from that episode. It features an early version of the super soldier serum from the MCU film Captain America: The First Avenger (2011), and includes references to several characters from that film.
"Know Your Onions" originally aired on ABC on June 3, 2020, and was watched by 1.50 million viewers. The episode received less positive reviews than the previous one, with critics highlighting several contrivances in the story and the disappointing end to the episode's central dilemma of whether to defeat Hydra or allow S.H.I.E.L.D. to be formed.
