How To Make Cajun Boiled Peanuts In Crock Pot [COMPLETE GUIDE]

Cajun boiled peanuts are a popular Southern snack that is both flavorful and addictive. These peanuts are boiled in a spicy and seasoned brine, allowing the flavors to penetrate the peanut shells, resulting in a delicious and unique snack. While traditionally made on the stovetop, you can also prepare Cajun boiled peanuts in a crock pot, which provides the added convenience of hands-off cooking. In this article, we will discuss the process of making Cajun boiled peanuts in a crock pot, including the selection of peanuts, preparation, cooking times, and troubleshooting common issues.

Quick Answer: How Long To Make Cajun Boiled Peanuts In A Crock Pot

Cajun boiled peanuts require several hours of cooking to obtain the desired texture and flavor. When using a crock pot, the cooking time can vary depending on the size and freshness of the peanuts. On average, it takes approximately 8 to 10 hours on the high setting, or 12 to 16 hours on the low setting. It is important to note that these times are estimates and may vary based on individual crock pot models and peanut quality.


Choosing the right peanuts is crucial for making delicious Cajun boiled peanuts. It is recommended to use raw peanuts, which are unroasted, unsalted, and still in their shell. Raw peanuts are readily available in most grocery stores, especially in the Southern United States, where boiled peanuts are a popular snack.

When selecting raw peanuts, ensure they are fresh and have not expired. One way to determine freshness is by considering the weight of the peanuts. Fresh peanuts will feel heavier in your hand compared to stale ones. Additionally, you can check for any signs of mold or discoloration, which indicate poor quality.

It’s important to note that the size of the peanuts will affect the cooking time. Smaller peanuts generally cook faster than larger ones. If you prefer a softer texture, opt for larger peanuts, while smaller ones will yield a crunchier texture.


Before cooking Cajun boiled peanuts, a few preparation steps are necessary to ensure the peanuts are ready for the crock pot.

  1. Soaking the peanuts: Soaking raw peanuts is an essential step that helps to soften them and allows the flavors to penetrate the shells during the cooking process. Start by placing the raw peanuts in a large bowl or pot and rinsing them under cold water to remove any dirt or debris. Once cleaned, cover the peanuts with water, ensuring they are fully submerged. Allow the peanuts to soak for at least 8 hours or overnight. The longer the peanuts soak, the softer they will become.

  2. Draining and rinsing: After the soaking period, drain the water from the peanuts and rinse them thoroughly under cold water to remove any excess salt or debris. This step ensures a clean and flavorful final product.

  3. Seasoning: The next step is to season the peanuts with Cajun spices to infuse them with the delicious flavors associated with this Southern treat. Cajun seasoning typically includes a blend of spices like paprika, cayenne pepper, garlic powder, onion powder, and salt. You can either purchase pre-made Cajun seasoning or create your own blend according to your taste preferences. Gently toss the drained and rinsed peanuts with the Cajun seasoning until evenly coated.

Crock Pot Cooking Times For Cajun Boiled Peanuts

Cooking times for Cajun boiled peanuts in a crock pot can vary depending on the size of the peanuts, the freshness, and the desired texture. Generally, the longer the peanuts cook, the softer they become.

  • High Setting: On the high setting, Cajun boiled peanuts usually take around 8 to 10 hours to reach a tender consistency. This shorter cooking time is ideal if you prefer your peanuts to have a bit of crunch.

  • Low Setting: If you prefer a softer and more tender texture, opt for the low setting on your crock pot. Cooking Cajun boiled peanuts on low typically takes around 12 to 16 hours. The longer cooking time allows the peanuts to become softer and soak up more of the flavors from the brine.

It is crucial to monitor the peanuts throughout the cooking process, especially towards the end, to ensure they reach the desired texture without becoming mushy. Additionally, the cooking times may vary slightly depending on your specific crock pot model and the quality of the peanuts.

How To Make Cajun Boiled Peanuts In Crock Pot

Now that you have selected and prepared your peanuts and are familiar with the cooking times, let’s dive into the step-by-step process of making Cajun boiled peanuts in a crock pot.

  1. Place peanuts in the crock pot: Start by placing the seasoned peanuts in the crock pot. Ensure they are evenly distributed and not overcrowding the pot, allowing room for the peanuts to absorb the flavors of the brine.

  2. Add water and seasoning: Next, cover the peanuts with water, ensuring they are fully submerged. The water should be approximately 2 inches above the peanuts. This will provide enough liquid for the peanuts to cook and soften.

  3. Additional seasonings: If desired, you can add additional seasoning to enhance the flavor of the boiled peanuts. This could include ingredients like hot sauce, bay leaves, or even extra Cajun seasoning. Remember that the flavor will intensify during the cooking process, so it’s better to start with a slightly milder seasoning blend.

  4. Cooking time and temperature settings: Set the crock pot to the desired temperature setting. If you prefer a crunchier texture, opt for the high setting and cook for approximately 8 to 10 hours. For a softer texture, use the low setting and cook for approximately 12 to 16 hours. It’s essential to monitor the cooking process during the final hours to prevent overcooking and ensure the desired consistency.

  5. Testing for doneness: After the suggested cooking time, carefully remove a few peanuts from the crock pot and allow them to cool slightly. Taste the peanuts to determine if they have reached your desired texture. If the peanuts are still too firm, allow them to continue cooking for an additional hour or two before retesting.

  6. Draining and serving: Once the peanuts have reached the desired texture, carefully drain them in a colander. Rinse them under cold water to cool them down and remove any excess seasoning. Once cooled and drained, the Cajun boiled peanuts are ready to be served! They can be enjoyed warm or at room temperature.

Troubleshooting Common Issues

While making Cajun boiled peanuts in a crock pot is a relatively simple process, there may be some common issues that arise. Here are a few troubleshooting tips to help you overcome these challenges:

  1. Peanuts are too firm: If the peanuts are still too firm after the suggested cooking time, continue cooking them for an additional hour or two. Check the texture regularly until they reach your desired consistency.

  2. Peanuts are too soft or mushy: If the peanuts become overly soft or mushy, they may have been cooked for too long. To prevent this, regularly monitor the crock pot during the cooking process, especially towards the end. Test the peanuts for doneness and remove them from the crock pot promptly once they are tender enough.

  3. Lack of flavor: If you find that the peanuts are not as flavorful as you’d like, you can add more seasoning towards the end of the cooking process. Additionally, adjusting the seasoning blend before cooking can help ensure a more flavorful result.

  4. Peanuts not absorbing flavor: If the peanuts are not absorbing the flavors of the brine, it could be due to the quality of the peanuts. Older peanuts may not absorb flavors as readily. However, adjusting the cooking time or allowing for a longer soaking period can help improve the flavor absorption.

Making Cajun boiled peanuts in a crock pot is a convenient and hands-off method to enjoy this delicious Southern snack. By following the steps outlined in this article, you can select the right peanuts, prepare them properly, and set the crock pot to achieve your desired texture. Remember to monitor the cooking process to prevent overcooking or undercooking and adjust the seasoning according to your preferences. Once cooked, these Cajun boiled peanuts are ready to be enjoyed as a savory and addictive snack that perfectly balances spice and flavor.

Achieving Perfect Texture

Cajun boiled peanuts are a popular Southern snack known for their unique taste and addictive flavor. Traditionally, they are boiled in a large pot on the stove for several hours until they become soft, buttery, and infused with spices. However, with the convenience of a crock pot, you can achieve the same delicious result with minimal effort.

One of the most important aspects of Cajun boiled peanuts is their texture. They should be soft, yet slightly firm, with a satisfying crunch. The crock pot method allows for slow and even cooking, ensuring that the peanuts retain their desired texture.

To achieve the perfect texture, start by selecting raw, uncooked peanuts. These can usually be found in the produce section of your local grocery store or at a farmers’ market. Raw peanuts have a higher moisture content, which makes them ideal for boiling.

Before cooking, it is essential to soak the raw peanuts overnight. This helps to rehydrate the peanuts and ensure they cook evenly. Place the peanuts in a large bowl or pot and cover them with water. Add 1/4 cup of salt for every pound of peanuts and stir well to dissolve. Soaking the peanuts in saltwater not only helps to rehydrate them but also infuses them with flavor.

Flavor Infusion

To achieve the distinct Cajun flavor in your boiled peanuts, it is essential to infuse them with a blend of spices. The key ingredients typically used in Cajun seasoning include cayenne pepper, paprika, garlic powder, onion powder, black pepper, and salt. However, you can also customize the spice blend according to your taste preferences, adding additional ingredients like thyme, oregano, or even a touch of smoked paprika for a smoky flavor.

To infuse the flavor into the peanuts, there are two techniques you can use: during the soaking process or during the cooking process itself.

If you prefer to infuse the flavor during the soaking process, simply add the desired amount of spices to the saltwater mixture. The longer the peanuts soak, the more flavor they will absorb. Overnight soaking is generally sufficient, but you can extend the soaking time for a more intense flavor.

Alternatively, if you prefer to infuse the flavor during the cooking process, there are a few methods you can try. One option is to add the spices directly to the crock pot. Mix the spices together in a small bowl and then sprinkle them over the peanuts before cooking. This method allows for a more concentrated flavor, as the spices come in direct contact with the peanuts. Another option is to tie the spices in a cheesecloth or place them in a muslin bag, creating a spice sachet that can be added to the crock pot. This method allows for easy removal of the spices after cooking, preventing them from overpowering the peanuts.


The aroma of Cajun boiled peanuts is intoxicating and adds to the overall sensory experience of enjoying this Southern delicacy. The combination of spices, salt, and peanuts creates a mouthwatering scent that wafts throughout your home while they cook.

To enhance the aroma while cooking, consider adding a few extra ingredients to the crock pot. Many Cajun boiled peanuts recipes call for the addition of garlic cloves, bay leaves, and even a splash of Worcestershire sauce. These ingredients not only add depth of flavor but also contribute to the tantalizing aroma that fills your kitchen.

Cooking Techniques

When it comes to the cooking technique for crock pot Cajun boiled peanuts, it is all about patience. Slow and low is the key to achieving perfectly cooked peanuts. The crock pot provides the ideal environment for slow cooking, allowing the peanuts to absorb all the flavors and become tender.

To start, drain the soaked peanuts and transfer them to the crock pot. Add enough water to cover the peanuts completely, ensuring that they are fully submerged. For added flavor, you can use chicken or vegetable broth instead of plain water. The broth will infuse the peanuts with richness and depth.

Set the crock pot to low heat and cook the peanuts for 12 to 18 hours. The exact cooking time will depend on the desired texture. If you prefer softer peanuts, cook them closer to the 18-hour mark. If you prefer slightly firm peanuts with a crunch, 12 to 14 hours should suffice.

It is essential to monitor the water level during cooking. As the peanuts cook, they will absorb some of the water, so it may be necessary to add more as needed. The peanuts should remain fully submerged to ensure even cooking. Additionally, stir the peanuts occasionally to promote even flavor distribution.

  3. Experiment with different spice blends and adjust the seasoning to your preferred level of heat and flavor.

  5. Keep an eye on the water level and add more as needed to keep the peanuts submerged.

  6. If you prefer a more intense flavor, cook the peanuts for the maximum recommended time.

  7. Allow the peanuts to cool in the cooking liquid to allow for further flavor absorption.
