This pre-packaged side dish is to die for.

This week, a Walmart Facebook ad for a mysterious bagged item called “Funeral Potatoes” caught the Internet’s attention.

The oddly named fare comes in a 13.6-ounce “food pouch.” The finished product resembles a creamy potato casserole, like potatoes au gratin.

Recipients of the targeted ad are just a bit perturbed.

“You’ve just gotta yell out loud “WTF?!?!?” when this Walmart ad pops up on your Facebook feed!” Chip Coffey, a television medium posted to his 24,000 Twitter followers. “LMAO Really?!? FUNERAL POTATOES?!?!?”

Another user took the ad more personally: “Is Facebook’s algorithm threatening me?”

Actually, no.

According to the Wall Street Journal, funeral potatoes are a beloved — and not at all malevolent — staple of church functions and yes, funeral repasts, made from shredded hash browns, onions, butter, cheddar cheese and sour cream, occasionally finished with a cornflake topping. Apparently, they’re so good they can make a grown food writer cry.

The name is regional to Utah and other Mormon enclaves.

For those in the know, the frenzy caused by Walmart’s ad is simply a chance to show some public love for the savory comfort food.

“They are SO good,” a young woman from Utah tweets. “I would baptize a bunch of dead people right now for a plate of funeral potatoes.”
