The TSA wants travelers flying home with delicious Thanksgiving leftovers to go stuff it – into their checked baggage.

Airport security will have their eyes peeled for anyone smuggling mashed potatoes – and other tasty banned Thanksgiving grub – at checkpoints after the holiday, the TSA warned Friday.

Leftovers like cranberry sauce, sweet potatoes and gravy, are forbidden in carry-on luggage, the TSA said on its website, citing a list of banned Thanksgiving dishes.

Any food that can be “spilled” or “spread” isn’t allowed on airplanes because it contains higher amounts of liquid, according to the “What Can I Bring” section of agency’s website. Wine, soup and salad dressing are also forbidden.

But travelers can bring more-solid foods – including Turkey, stuffing, butternut squash and green beans – on the plane for a snack. Cakes and some types of pies are also fine, the TSA said without elaborating.

The only way to get around the ban may be to pack a tiny portion.

“Gravy is sadly prohibited from carry-on bags unless you pack it in accordance with our [under 3.4 ounce] liquid polices mentioned above,” the TSA said on its blog.

Roughly 27.3 million passengers are expected to travel worldwide on U.S. airlines over Thanksgiving, up 2.5 percent from last year, according to the TSA.

A spokesman for the TSA didn’t respond to requests for comment immediately Friday.
