To make boiled peanuts in a Crock-Pot or slow cooker, add peanuts, salt and water, and cook the ingredients until soft. If desired, add Creole seasoning, garlic and hot sauce to the mixture.
Use green peanuts to make boiled peanuts. Green peanuts are raw and smaller than regular peanuts, since they are harvested sooner. Regular peanuts do not produce the same results.
Before placing the peanuts in the slow cooker, wash the shells thoroughly until the water runs clear. When they are clean, put the unshelled peanuts in the slow cooker, and add salt. For 1 1/2 quarts of unshelled peanuts, add 1/2 cup of salt. Cover the ingredients with water, adding 2 1/2 quarts for every 1 1/2 quarts of peanuts.
Place the lid on the slow cooker. Cook the peanuts on high for five to seven hours or on low for nine to 11 hours. Add more water during the cooking process if needed. Boiled peanuts are done when they are soft. If they aren't salty enough after cooking, turn off the slow cooker, and allow them to rest in the salted water.
Add flavor to boiled peanuts by adding 4 tablespoons of Creole seasoning, 1 tablespoon of hot sauce and 2 cloves of garlic. Stir in the seasonings when adding the salt to the slow cooker.
