Preheat the oven to 350 degrees Fahrenheit.
Place peanuts on a baking pan in a single layer. It’s okay if they are crowded.
For shelled peanuts you can bake them for 15-20 minutes. If they are done baking, the skin should be loose and the peanuts should be golden brown.
If you want to salt the peanuts, you can add the salt once they are out of the oven.
Allow the peanuts to cook for a few minutes before consuming.
