2-Ingredient Crockpot Boiled Peanuts
Crockpot boiled peanuts are the set-it-and-forget-it way to get that salty, tender Southern snack at home. There is no standing over a hot stove. Just raw peanuts, salt, and water, then your slow cooker transforms them into something special.
They taste just like the ones from the roadside stand, with shells that slip right off and peanuts that are soft and creamy. Perfect for game day, a beach trip, or a lazy afternoon on the porch.
Why These Crockpot Boiled Peanuts Are So Good
The slow cooker’s steady low heat coaxes out a deep nutty flavor without any effort from you. I love how hands-off this recipe is. You rinse the peanuts, dump them in with salt and water, and walk away for hours.
When you come back, the peanuts are tender and briny, with a rich roasted note that only a long simmer can bring. The brine tastes like the ocean in the best way, and the peanuts soak it all up.
Ingredients
- 1 lb raw peanuts in the shell: Look for green (fresh) or dried raw peanuts, never roasted.
- 3 tbsp kosher salt: This makes a brine that tastes like seawater; adjust to your liking.
- Water: Enough to cover the peanuts by at least an inch.
Variations / Substitutions
- Add heat: Stir in 1 tablespoon Cajun seasoning or a few generous pinches of crushed red pepper.
- Garlic and bay: Toss in 4 smashed garlic cloves and 2 bay leaves for extra depth.
- A little sweet: Stir in 1 teaspoon of sugar for that classic Southern sweet-salty balance.
- Low sodium: Use 2 tablespoons of salt and taste the brine before cooking.

How To Make Crockpot Boiled Peanuts
Step 1: Load the Crockpot
Rinse the 1 lb of raw peanuts well under cold water, picking out any stems or loose debris. Pile them into a 6-quart slow cooker, then add the 3 tablespoons of kosher salt and enough water to cover the peanuts by at least an inch. Give it a stir, then taste the water. It should be nicely salty, like sea water. If it tastes flat, stir in another pinch of salt.
Step 2: Cook Low and Slow
Cover the slow cooker and set it to low. Cook the peanuts for 20 to 24 hours, until the shells look swollen and the peanuts inside are soft and creamy. Check occasionally and add a splash of hot water if the level drops below the peanuts. Near the end, the brine will turn a deep nutty brown and your kitchen will smell amazing.
Step 3: Drain and Serve
Drain the peanuts in a colander, letting the hot brine run off. Pile them into a bowl and serve warm, right out of the shells. Eat them while they are still hot and salty, with plenty of napkins nearby.
Tips for the Best Crockpot Boiled Peanuts
- Salt like the ocean: The brine should taste as salty as seawater. Do not be shy; the salt only penetrates the shell, so the peanut itself will not be overly salty.
- Top off as needed: Check the water level after 10 hours. If the peanuts have soaked up too much water and are no longer submerged, add hot water to keep them covered.
- A little sugar goes a long way: Adding a teaspoon of sugar to the brine does not make them sweet; it just rounds out the saltiness and gives them that classic roadside stand flavor.
- How to check doneness: Pull out a peanut after 20 hours, let it cool slightly, and taste it. It should be soft and creamy, not chalky. If it still has a raw crunch, let them cook another 2 to 4 hours.
Cook times by setting:
| Slow Cooker Setting | Approximate Time |
|---|---|
| Low | 20 to 24 hours |
| High | 10 to 12 hours |
Storing Leftover Boiled Peanuts
- Refrigerate: Let them cool, then store in an airtight container with some of the brine. They will keep for up to a week.
- Reheating: Warm them in the microwave or back in a pot of brine on the stove. They are also good cold.
- Freeze: Drain and freeze in zip-top bags for up to 3 months. Thaw and reheat in brine.
Frequently Asked Questions
Can I use roasted peanuts?
No, you need raw, dried, or green peanuts. Roasted peanuts will never soften, no matter how long you cook them.
My peanuts are still hard after 24 hours. What went wrong?
They may have been old or too dry. Continue cooking on low for another 4 to 6 hours, checking the water level and adding more as needed. Older raw peanuts can take longer to tenderize.
Can I add Cajun seasoning to the brine?
Absolutely. Stir in a tablespoon or two of Cajun or Creole seasoning with the salt for a spicy version. You can also add a halved onion or a few garlic cloves.
How long do boiled peanuts last?
In the fridge, they keep for 5 to 7 days in an airtight container with some of their brine. They also freeze well for up to 3 months.
