In iWill Date Freddie, Spencer serves them to Freddie and his date. In iPie, Spencer made them for Trudy when she came over to his house for dinner. In iCook, Carly, Sam, and Freddie were challenged to a spaghetti taco Food Fight with Ricky Flame (in which they were to cook the same dish, and the judges would decide which version was better), which they won. They are made of spaghetti, meatballs, and taco shells. They also contain Peruvian Puff Peppers, which is a reference to Drake & Josh, one of Dan Schneider's previous shows. The iCarly gang won the competition, AND a year supply of free steaks.
In the episode iFind Spencer Friends, Spencer and the iCarly gang celebrate Spencer's birthday with a large spaghetti taco with candles on top.
Schneider initially created spaghetti tacos as a joke for the iWill Date Freddie episode broadcast on November 10, 2007. However, over the years, the formerly fictional delicacy became a popular dish in real life, imitated and experimented on in various ways by thousands of tweens and parents nationwide, although they usually do not contain meatballs - the one part of the recipe that didn't catch on. The dish was even enjoyed by the cast members: Nathan Kress recalls making and consuming some on a day when craft services served spaghetti and had some taco shells lying around.
- Recent uses of the spaghetti taco include a Mexican version and a dessert version.
- Spaghetti tacos have also been mentioned in the Victorious episode "Jade Gets Crushed."
- Dan Schneider himself never had a real spaghetti taco (save for the recipe his wife made) until April 2011.
- In November 2011, his wife shot an episode of her cooking show, "Hungry Girl", alongside Miranda and they made Spaghetti Tacos.
