Kim and Ron hurry back to school after a mission, hoping to sign up for their preferred elective classes. However, Bonnie ends up getting the last spot in photography, so their only remaining option is Home Economics. At first, the class looks hopeless, with the two of them as the only students in a dusty deserted classroom. However, Ron turns out to have a knack for cooking, so Barkin turns the class over to him, while Kim struggles with the class. Meanwhile, Seņor Senior Senior decides that Junior needs some lessons in proper villainy, and hires Shego to tutor him.

After getting off to a slow start, Junior begins to improve, but Senior becomes jealous of the relationship the two have and misses teaching his son the finer points of villainy. Meanwhile, Ron becomes enough of a chef that he's given control of the food at Middleton High, with an embarrassed Kim as his helper. Much later, Junior hones his skills enough, Shego decides that he's ready to test his skills in the field by pulling off a caper -- stealing the secret recipe for Granny Crocket's chocolate-chip cookies.

Figuring out what the pair is up to, Kim & Ron attempt to warn Granny, but are dismissed, (as a disguised Senior already tipped them off), and they are confident their security can handle things. The two villains effortlessly make it through the security, only to find Team Possible waiting for them. During the fight, Kim uses the advice Ron taught her to escape a giant mixer, and Shego & Junior are sent to jail. But the police pilot turns out to be Senior, who dismisses Shego of her tutor duties. Back at school, Ron's restaurant is closed down, but Kim gets a little bit better at cooking, thanks to his training.

!!This episode provides examples of:
* AffectionateGestureToTheHead: The Texan at Granny Crockett's place does this to Kim (in addition to calling her little missy).
* BoringReturnJourney: Subverted. The episode begins with Kim and Ron parachuting out of a plane. The audience assumes that they're headed for a mission, but in fact they're headed back to school.
* ByTheLightsOfTheirEyes: Seņor Senior Senior, annoyed at being shut out as Shego works with Junior, sends a video warning to the target of their upcoming heist. He records the message in a dark room with only his eyes showing... until Junior barges in and turns on the lights.
* ContinuityNod: Francois and Le Goop hair gel are [[Recap/KimPossibleS1E3TheNewRon again featured in an episode with the Seniors]].
* DepartmentOfRedundancyDepartment: When picking electives, you should, as Ron notes have a backup and a backup for your backup.
* DumbassHasAPoint: When Shego can't think of a suitable field test for Junior's training, Junior suggests doing a web search for "really valuable" and "heavily guarded", which leads them to select Granny Crocket's recipe as their target.
** StrangeMindsThinkAlike: Later, when the heroes try to guess the villains' next move:
---> '''Kim:''' The Seniors are all about the challenge, they only go for stuff that's really valuable and heavily-guarded.\\
'''Ron:''' You know, we could just run a web search on the words "really valuable" and "heavily-guarded".\\
'''Kim:''' Ron, we're talking a devious criminal mind here. It's not as simple as...\\
'''Wade:''' Got it! Great idea, Ron.
* EvilPlan: Shego says this is the most important thing an evil villain must have.
* GrandmaWhatMassiveHotnessYouHave: Granny Crockett certainly looks way younger than the woman on the cookie packages.
--> '''Granny Crockett:''' Well, Granny had a little work done.
* HeadphonesEqualIsolation: Shego catches Junior listening to music instead of listening to her. She solved the problem by grabbing and crushing his music player.
* IThoughtItMeant: Upon hearing its name, Ron assumed that Home Economics was about financial planning.
* TheLastOfTheseIsNotLikeTheOthers: A double version. While investigating the rash of robberies in Paris, Kim and Ron learn from each store that the thieves took a set of two burglary items...until the last store turned out to be Fracois', the hair stylist, and they learned that ''all'' of his hair gel was stolen.
* TheMagazineRule: "Villain's Digest? Bad guys have their own magazine?"
* NotMeThisTime: An indirect example. When Francois (from [[Recap/KimPossibleS1E3TheNewRon "The New Ron"]]) describes the duo who robbed his salon, he mentions a large but not terribly bright boy, who Kim correctly guesses to be SSJ. However, his partner was ''not'' SSS, but "a young lady" with "glowing green hands".
* PrivateTutor: Seņor Senior Senior hires Shego to teach Junior how to be a proper villain.
* ShoutOut: [[Film/TheEmpireStrikesBack "That Kim, is why you fail"]].
** When he sets up "Chez Ron" in the school, he uses his trademark phrase "booyah" not unlike Emeril Lagasse.
* SupremeChef: Ron's cooking is so good that the students desert the cafeteria in favor of "Chez Ron" and clamor to get into home economics class.
* ThirdWheel: Seņor Senior Senior is made to feel like an outsider as every attempt to check in on Junior's progress or offer advice gets brushed off. He does not take this well.
* TrojanPrisoner: After Junior and Shego are defeated, a police helicopter arrives to pick them up. It turns out to be a fake piloted by Seņor Senior Senior, who dismisses Shego and takes Junior home to "polish our {{evil laugh}}s together".
* VillainTeamUp: Shego and Junior work with each other rather than their usual partners in crime.
