Dry roasting peanuts is easy!. At our house, roasting is the first step to the chocolate covered peanuts I make for Christmas every year.
We roast the peanuts we grow. If interested, you can see how I harvested my peanut crop here. BTW, anyone can grow peanuts. If it is too cold for peanuts where you live, you can grow them in pots. You can also purchase raw peanuts at the grocery store and roast them. They are a great treat at Christmas parties! The scent of roasting peanuts will fill the house!
Here is how you do it:
Preheat the oven to 350 degrees. Spread the peanuts out on a cookie sheet. (A cookie sheet with a rim works best.)
Roast the peanuts for 20 - 30 minutes. If you have smaller peanuts like Spanish, roast for 20 minutes. If you have larger peanuts like Virginia Jumbo, roast for 30 minutes. At about the halfway point, stir and turn the peanuts over to prevent burning. This is why you use a cookie shee with a rim. When stiring and turning the peanuts, they will fall off a flat cookie sheet. Ask me how I know this! It is quite difficult to reach the peanuts that fall to the bottom of the oven without removing the oven racks! Here is a picture of my peanuts at the half way point.
When the peanuts are done, remove from the oven and turn them onto a plate or another cookie sheet. They will continue to cook while they are cooling so it is best to remove them from the hot cookie sheet so they don't overcook.
Once they are cooled, you can store them in the shell until you are ready to eat!
