For 20 people, buy a 30-pound turkey. It’s the safest bet. If you’re scared of the size, get two 15-pounders. Double the birds, double the fun.
Don’t overthink it. You’re feeding a small army. You’re a hero. You’re the turkey whisperer.
Now go forth and roast. Make sure your oven is empty. And maybe buy a fire extinguisher. Just in case. Happy Thanksgiving, you magnificent bird-wrangler.
