In PaperCity’s December print issue, we take readers inside the Highland Park home of Cornelia Guest, an iconic New York party girl and recent Dallas transplant. Armed with lessons from her late mother, C.Z. Guest, a legendary socialite immortalized through the lens of photographer Slim Aarons, Guest throws a killer dinner party, with one staple you can always count on during the holidays: vegan shepherd’s pie. (Guest became a vegetarian, then a vegan, after learning how animals are abused on factory farms.)
“It’s such a yummy dinner with a salad on a cold winter’s night,” she says. “My friends laugh because every time I invite them over, we have Shepherd’s Pie. Luckily, everyone loves it.”
Ahead, Guest shares the recipe for her favorite vegan shepherd’s pie.
