This is my Dad's recipe and could not be easier. Just remember, turn off the oven and don't take them out or even open the door for 1 hour.
Love roasted peanuts. Make sure you read the directions, the oven is turned off while the peanuts are in it. Came out perfect! - 09 Aug 2009 (Review from Allrecipes US | Canada)
Trick here is to know when your oven is adequately "pre-heated"....which is difficult with my oven. However, following the directions, the peanuts were no longer raw at the end of the hour, but I probably could have left them in another five or so minutes--or preheated my oven longer. Very simple recipe which works. - 13 Jan 2008 (Review from Allrecipes US | Canada)
This works better if you put the peanuts in the oven, then turn it on. Just be sure to turn the oven off when it reaches 500 degrees, then leave them for an hour. - 27 Nov 2007 (Review from Allrecipes US | Canada)
