How long does it take to bake a yam?
The folks at Cooks Illustrated write in their ever-so-modestly titled tome The Best Vegetable Recipes that the best way to make baked yams and sweet potatoes is to lightly coat them in vegetable oil, pierce 'em multiple times with a knife, and stick them in a 400°F oven for 45 minutes to an hour.
What temperature should yams be cooked at?
Preheat oven to 425 Farenheit. (Test oven temperature with thermometer to make sure your oven thermostat is correct.) Scrub yams with veggie brush under running cold water. This will abrade the skin enough so you don't have to make slits in them.
How long does it take to bake sweet potatoes at 400 degrees?
Bake whole sweet potatoes in a 400 degree oven for 45-60 minutes. Larger sweet potatoes will take closer to 1 hour to cook while smaller ones can be ready in as little as 40 minutes.
What temp should a sweet potato be cooked to?
I typically bake sweet potatoes between 45 to 55 minutes in a 400 degree F. oven. You can check the internal temperature of your sweet potatoes with an instant-read thermometer -- you'll want them to be between 205 to 212 degrees F. in the thickest part of the potato when they're done.
