Slow-cooker boiled peanuts are simple and mostly hands-off: simmer raw green or raw shelled peanuts in plenty of water with salt for hours. In this guide we show exactly how to boil peanuts in the crock pot — precise times, salt ratios, seasoning ideas and troubleshooting tips.
Why use a crock pot for boiled peanuts?
Using a crock pot is the easiest way to make tender, flavorful boiled peanuts because it keeps a low steady temperature for long periods—exactly what peanuts need. A crock pot set to LOW for 8–12 hours gently breaks down the peanut kernels so they go soft without bursting or drying out.
The slow, even heat lets salt and any seasonings fully infuse, and you don’t have to babysit a simmering pot on the stove. We like the crock pot for weeknight prep or when company’s coming — set it in the morning and it’s ready by evening with almost no effort.
Ingredients & equipment
Here’s what you need to make classic boiled peanuts in a crock pot: raw green or raw shelled peanuts, coarse salt, and water. You can add flavorings like bay leaves, garlic, or Cajun seasoning for a spicy twist.
- 4–5 lb raw green peanuts (or 2–3 lb raw shelled peanuts)
- Salt: 1/4–1/2 cup per quart of water (see timing section)
- Water to cover by 2 inches
- Optional: 2–4 bay leaves, 4 crushed garlic cloves, or 2–3 tbsp Cajun seasoning
- 6–8 quart crock pot (large slow cooker)
We recommend a 6–8 quart slow cooker for a 4–5 lb batch so the peanuts can move freely and the water stays well circulated. If your crock pot is smaller, halve the batch so everything cooks evenly.
Step-by-step: How to boil peanuts in the crock pot
To boil peanuts in the crock pot, combine raw peanuts, cold water to cover by about 2 inches, and salt, then cook on LOW for 8–12 hours or on HIGH for 4–6 hours until tender. Stir once or twice during the first hour, then leave the lid mostly closed to hold heat.
We tested this with green peanuts and with fresh raw shelled peanuts; green peanuts are more forgiving and take the full low-time for that classic buttery texture. If you’ve got a large batch, check for doneness at the early end of the range—crowded peanuts take a touch longer.
- Rinse peanuts under cold water and pick out any shriveled pieces or debris.
- Place peanuts in the crock pot and add enough cold water to cover them by about 2 inches.
- Add salt: start with 1/4 cup salt per quart of water for mildly seasoned peanuts; increase to 1/2 cup for traditional Southern-level saltiness.
- Add optional seasonings like bay leaves, crushed garlic, or 2–3 tbsp Cajun blend and give everything a stir.
- Cover and cook on LOW for 8–12 hours or on HIGH for 4–6 hours. Check for tenderness at the short end of the range.
- When tender, turn off the crock pot and let peanuts sit in the brine for at least 30 minutes to absorb more flavor, then drain and serve warm or cool before storing.
Sarah learned the hard way that skipping the sit-in-brine step leaves the peanuts bland; letting them steep 30–60 minutes after cooking makes a noticeable difference. If you like stronger flavor, we sometimes leave them in the crock pot base for an hour while the unit cools down.
Timing, salt, and flavor variations
Cook times depend on peanut type and crock pot heat: LOW 8–12 hours is the most reliable, while HIGH 4–6 hours works if you’re short on time—either way, tender kernels are the sign of doneness. Use the fork test: skin should slide off and the kernel yields easily.
Salt is where many people go wrong: under-salted peanuts taste flat and over-salted peanuts are hard to fix. Start with 1/4 cup kosher salt per quart for a gentle seasoning, or up to 1/2 cup for classic southern boiled peanuts; remember the peanuts absorb a lot of brine as they cook.
For flavors, add a few bay leaves and a smashed garlic clove for a subtle aromatic base, or stir in 2–3 tablespoons Cajun seasoning at the start for a spicy batch. If you want a smoky note, toss in a couple of smoked ham hocks—just be mindful that meat will add salt and richness.
Storage, reheating and common mistakes
Store cooled boiled peanuts in an airtight container in the fridge for up to 7 days, or freeze in portions for up to 3 months; thaw overnight in the fridge and reheat gently. To reheat, warm in a pot with a splash of water for 10–15 minutes or use the crock pot on LOW for 1–2 hours.
A common mistake is crowding the crock pot or using too little water—both slow cooking and uneven doneness. Daniel swears by the 2-inch water rule: if the water level drops during cooking, top it up with boiling water to keep the peanuts submerged and cooking evenly.
- Pro tip: If peanuts test undercooked, keep cooking and sample every 30–60 minutes; doneness can vary by batch.
- Don’t add dairy or delicate herbs at the start; add finishing seasonings after cooking if you want brighter flavors.

Quick-reference summary
Want the short version? Rinse raw peanuts, cover by 2 inches of water, add salt at 1/4–1/2 cup per quart, and cook LOW 8–12 hours or HIGH 4–6 hours. Taste for tenderness and let them sit in the brine for 30–60 minutes before serving.
- Best peanuts: raw green peanuts for classic results; raw shelled peanuts also work.
- Salt guideline: 1/4–1/2 cup kosher salt per quart of water.
- Finish: optional Cajun seasoning, garlic, or bay leaves added at start.
