“Kentucky nachos” is a variation of nachos. Like potachos, “Kentucky nachos” replaces tortillas chips with potato chips. Barbecued pulled pork is a featured ingredient, and blue cheese, coleslaw, cheddar cheese, sauteed onions and peppers are other ingredients.
 
The origin of the food is unknown, but it was served at Churchill Downs for the 2006 Kentucky Derby. Kentucky Nachos was popularized in June 2009 on the website This is why you’re fat.
