Pie

Pie is a recurring delicacy favored by Dean Winchester.

Overview
The first mention of Dean liking pie appeared in season 1 episode "Scarecrow", in which the townsfolk of Brkitsville, Indiana annually sacrifice young couples to a pagan god. The couples are fed pie before their sacrifice. As Dean is held captive and prepared for sacrifice, he exclaims : "I hope your apple pie is freakin' worth it!"

Since then, Dean has made numerous mentions about wanting pie, though a recurring gag is that he rarely ever does get his pie.

In season 5 episode "Dark Side of the Moon", it is implied that the origin of Dean's love for pie comes from Mary, who was shown in a memory making him pie. Dean also seems to associate pie with comfort, possibly because of his mother.

Pie is also used as a metaphor to mean "a normal, hunting-free life". This phrase first appeared in season 1 episode "Pilot", when Dean accuses Sam of running off to have an "apple-pie life".

The song "Cherry Pie" by Warrant also appeared in season 4 episode "Sex and Violence", season 5 episode "The Song Remains the Same" and season 10 episode "Reichenbach".
