We love roasted peanuts in everything from granola to slaws and salads. But we have found that it is much cheaper to buy raw peanuts in bulk and to roast them at home. This is quick and easy, and it lets us control the roasted flavor more precisely.
What You Need
Ingredients
Raw shelled peanuts
Salt (optional)
Equipment
Large rimmed baking sheet
Instructions
1. Start with raw, shelled peanuts. We usually buy blanched peanuts, with the skin removed. But this will work fine on unblanched peanuts; there will just still be a red, papery skin on the nuts.
2. Heat the oven to 350°F. Spread the peanuts in one layer on a large rimmed baking sheet. I usually roast about two cups at a time.
3. Roast for 20 to 25 minutes.
4. Stir at least twice during the roasting time. When they smell peanutty and roasted, remove them from the oven and let cool before transferring to a sealed container, or using them in a recipe.
That's it! We told you it was easy. Personally, I really love the taste of freshly roasted peanuts. They have this depth of flavor and yummy nuttiness that just isn't found in commercially roasted peanuts. They taste fresher and more peanutty. Plus, roasting them makes your house smell great.

You can also roast peanuts in the microwave... seriously. Just do two-minute bursts on slightly reduced power and they roast right up. Works for my peanut butter!
I read a great tip from Alton Brown for removing the skins. After toasting, give the peanuts a spin in the salad spinner. It's not perfect, but you end up with a lot more bare peanuts that way!
When buying raw peanuts be sure to keep an eye out for aspergillus flavus a peanut and corn mold know to cause a metabolic production of a carcinogen known to cause liver cancer. Roasting peanuts as soon as possible retards the mold's ability to grow but does not necessarily kill it. So there are extra dangers in buying peanuts raw.
Before you roast them, you will need to soak them in salty water for 7-9 hours -- otherwise they will be hard to digest (and may even rob vital nutrients from your body).
