• Nicely wash the shelled peanuts to remove any dirt. Drain the water. 
  4 cups Peanuts
• Add enough water to cover the peanuts, salt, and cajun seasoning, and cook the peanuts using your preferred method – pressure cooker, instant pot, stovetop (stockpot), or slow cooker crockpot. All the methods will give the same result except for the time it takes to cook. 
  2 tablespoon Salt, 2 tablespoon Cajun seasoning
• The fastest way for me is definitely the pressure cooker method. 

HOW TO MAKE CAJUN BOILED PEANUTS IN A PRESSURE COOKER?

• Cooking peanuts in a pressure cooker is the easiest and fastest method and my most preferred method. By pressure cooker, I mean the one that is available in India. Some of the common pressure cooker brands are Butterfly, Prestige, Pigeon, etc.
• Pressure cook on a medium flame for 3 to 4 whistles. Let the pressure release naturally. The total cook time is between 15 to 20 minutes. Check out the video for preparing cajun boiled peanuts.

HOW DO YOU MAKE CAJUN BOILED PEANUTS ON A STOVETOP?

• Place a large pot (stockpot) on the stovetop. Add washed peanuts, salt, and cajun seasoning and cover them with water. Bring the water to a boil and cook on medium-low flame for 3 hours or until the peanuts are cooked through.

HOW DO YOU MAKE CAJUN BOILED PEANUTS ON A SLOW COOKER CROCKPOT?

• Once you have added washed and drained peanuts (i.e., with the shell on) to your crockpot, add water, cajun seasoning, and salt, and cook on high for 10 to 12 hours or until peanuts are cooked through.

HOW DO YOU MAKE CAJUN BOILED PEANUTS IN AN INSTANT POT?

• Add the washed and drained shelled peanuts, salt, cajun spice mix, and enough water to cover the peanuts and mix. See that you do not exceed the maximum water level allowed on your IP. Place the steamer rack to help the peanuts weigh down. Cover the lid and see that the valve is in a sealing position.
• Set the pressure cooker for 75 minutes. After that, let the pressure release naturally for 30 minutes and release any remaining pressure.
• Remember, after the peanuts are boiled, the peanuts should be soft and creamy like canned beans and not be hard/firm. If they are hard/firm, you will have to boil the peanuts for more time.

HOW TO EAT BOILED PEANUTS WITH SHELLS?

• Drain the briny liquid using a strainer. Open the shell by pressing them with the help of your fingers and enjoy the soft and creamy goodness inside.
