My love for boiled peanuts dates back to my childhood, when I lived in Charleston, South Carolina and Jacksonville, Florida.

The southern staple snack was sold from hot kettles in roadside stands, often in brown paper bags or Styrofoam cups.

Our favorite stand was run by a man we all affectionately referred to as, “The Peanut Man.” I don’t even know his real name, but I do know he was a super nice guy who made some amazing boiled peanuts.

You could often find two different varieties for sale: plain or Cajun.

Both versions are salty and delicious, but the Cajun variety has a spicier flavor.

Since I now live in an area where boiled peanuts are nowhere to be found, I needed to figure out a way to make some boiled peanuts recipes myself!

After I learned how to make boiled peanuts in the Instant Pot, I created a recipe for Crockpot boiled peanuts, since I know not everyone has a pressure cooker yet.

More recently, I tried my hand at Instant Pot Hawaiian boiled peanuts, at the recommendation of my readers, which were uniquely different from Southern boiled peanuts.

Next came Instant Pot Cajun boiled peanuts. They were really tasty, so naturally, I knew I needed to make a recipe for Crockpot Cajun boiled peanuts as well. I can’t leave my slow cooker lovers in the dark!

Cajun Boiled Peanuts in the Crockpot

Making boiled Cajun peanuts in the Crockpot is a super simple process. All you need is some raw peanuts, coarse sea salt, Cajun seasoning, and hot sauce. Some people like to use shrimp and crab boil for their peanuts, so that’s an option, too!

I’m going to preface this by saying that I am a wimp when it comes to spice, so I purposely made mine fairly mild.

If you like things extra spicy, you’ll want to ramp up the hot sauce. You could even add in some sliced jalapenos if you want!

Everything gets combined in the Crockpot and cooked on high for a few hours, creating tender boiled peanuts!

Where Can I Find Raw Peanuts?

I have found raw peanuts at Walmart and other grocery stores in my area, such as Kroger and Publix.

Sometimes Walmart has them in the nuts section, but most grocery stores keep them in the produce section.

If you can’t find them locally, you can also order them from Amazon.

You’ll want to make sure you are using raw peanuts in the shell, NOT roasted peanuts. If you have access to green peanuts (raw peanuts that haven’t been dried), you can use those, too!

  • 1 lb raw peanuts in the shell (not roasted)
  • 1/4 cup coarse sea salt

  • 1-2 Tbsp hot sauce (or more to adjust to taste; see recipe notes below)
  • About 6-8 cups of water

  1. Rinse and sort peanuts, discarding any debris or peanuts that are cracked or broken.
  2. Combine peanuts, salt, Cajun seasoning, hot sauce, and enough water to generously cover the peanuts in the slow cooker.
  3. Cook on the high setting for 5-7 hours, or until the peanuts are tender. Stir occasionally during cooking to make sure all of the peanuts get good exposure to the liquid (because they will initially float), and add more water as needed to keep the peanuts covered.

Recipe Notes and Adaptations:

  • If you prefer spicier peanuts, feel free to increase the hot sauce. As written, this recipe yields a fairly mild spice level. You can also add sliced jalapenos if you want an even spicier version. Feel free to increase the Cajun seasoning to taste, adding as much as 1/4 cup, if preferred (this will also make them saltier, so you may want to decrease the salt a bit if you increase the Cajun seasoning).
  • Storing the peanuts in their brine will allow the flavor to soak in even more.
