Back in 1987, President Reagan declared June 25 National Catfish Day, and thus the awful glorious tradition of designating food “holidays” was born. Now there are over 635 days on the books, celebrating everything from gazpacho to strawberry ice cream.

While food holidays are totally arbitrary and useless, they present an opportunity to celebrate food—which we can’t hate on. Take Potato Chip Day, for example, which just so happens to fall on National Pi(e) Day (a.k.a., March 14, or 3/14). How could we pass that one up? It’s like a lunar eclipse of comfort food.

From an apple galette with crunchy Kettle Chip topping to a potato-chip-and-cheese pie, here are 10 recipes that celebrate the convergence of Potato Chip and Pi(e) Day.

Potato Chip Pie

Recipe: Oh Bite It

This savory pie celebrates the goodness of gooey au gratin—but you don’t have to deal with slicing potatoes painstakingly thin. Just fold the contents of a chip bag into a sour cream-milk mixture and cover in cheese. (Photo: Oh Bite It)

Chocolate Porter Mousse Tart with Potato Chip Crust

If you can get behind sweet and salty pretzel chocolate chip cookies, give this rich chocolate ganache tart a try. Crumbled kettle chips lightens up the crust and provides just enough sea salt to keep things interesting. (Photo: What’s Gaby Cooking)

Duck Fat Potato Galette
