The turkey is the crown of your holiday table, so what size should you get? And how hungry will your guests be?

Chef Karen Fischer with the Montclair Culinary Academy wrote it all out for us.

“One pound of cooked turkey per person,” she said.

She says count kids as a quarter pound, and when buying the bird, consider it has bones, so for eight people, buy a turkey that is at least 10 pounds.

Side dishes should be about a half pound per person.

“You don’t have to reach into the oven and flip anything, it just will roast through both sides,” she said.

For traditional baked potatoes, Fischer says a large potato can feed two people.

Fischer says never make mashed potatoes ahead of time and don’t over-mash them because they are a starch and will get gummy.

If you have vegetarian guests, an easy main course for them is vegetarian wellington.

“Oyster mushrooms are beautiful. They’re meaty,” she said. “Some Swiss chard, so this is truly a vegetarian’s dream.”

Wrap it up in a crescent roll and bake for 10 minutes on 400 degrees.

As for the wine, Fischer says, “Be prepared for hearty drinkers.”

“If you’re making all of the food, the thing to request is bring the salad, the dessert and, oh, bring your favorite wine, so people will know so the pressure isn’t on the hosts to figure out what everybody wants to drink,” she said.
