I once cooked for a Thanksgiving where I bought two pounds per person because I got scared. Let’s just say my family ate sweet potato casserole for a week. We’re still finding orange crumbs in the couch cushions.
The truth is, sweet potatoes shrink a bit when cooked. They lose water, so a big raw potato becomes a humble, tender nugget. Always err on the side of ½ pound for sides, especially if you have other heavy hitters like turkey or ham. No one wants a potato avalanche.
For the Classic Side Dish (Mashed, Roasted, or Candied)
Think of this as the “I’m not trying to be a hero” scenario. You’re serving sweet potatoes alongside other dishes. Aim for ½ pound (8 ounces) per adult. That’s about one small-to-medium potato per person.
For kids, cut that in half—they’ll probably eat the marshmallows on top anyway. If you’re feeling generous or have hungry teenagers, go ahead and round up to ¾ pound. Teenagers are bottomless pits of hunger and joy.
When Sweet Potatoes Are the Star of the Show
Let’s say you’re doing a “Sweet Potato Bar” with chili, cheese, and sour cream. Or maybe you’re making stuffed baked sweet potatoes. In that case, plan for 1 pound per person. That’s a nice, generous serving that fills people up without sending them into a food coma.
If your guest is a serious athlete or your Uncle Bob who eats like a prehistoric cave dweller, you might need 1.5 pounds. Uncle Bob knows who he is. Just give him the biggest potato and watch him smile.
