How Long Does Raw Peanuts Last
Peanuts are a seriously popular snack, and for good reason! They’re tasty, packed with healthy fats and protein, and a versatile ingredient besides. But if you’ve got a stash of raw peanuts, you might be wondering how long they’ll stay at their best. Well, the answer depends on a few factors, like whether they’re shelled or unshelled, and how you store them. Let’s dive into the details!
Understanding Peanuts: Shelled vs. Unshelled
First things first, let’s get clear on the difference between shelled and unshelled peanuts:
- Shelled peanuts: The peanut kernels are exposed, with the protective shell removed.
- Unshelled peanuts: The peanut kernels are still nestled inside their shells.
This distinction matters for storage because the shell acts as a natural barrier against going rancid.
How Long Do Raw Peanuts Last at Room Temperature
If you’re storing peanuts at room temperature, here’s a quick guideline:
- Shelled peanuts: Last around 3 months
- Unshelled peanuts: Can last up to 6 months
Important Points about Room Temperature Storage
- Keep it cool and dry: The ideal spot is a dark, cool cupboard or pantry away from direct sunlight and heat sources.
- Airtight containers are your friend: This helps prevent moisture and pests from getting at your peanuts.
- Look out for signs of spoilage: These include an off-odor, mold, or an overly shriveled appearance.
Refrigerating Raw Peanuts: The Best Way to Extend Shelf Life
The fridge is the key to maximizing how long your raw peanuts last. Here’s the breakdown:
- Shelled peanuts: Can last up to a year
- Unshelled peanuts: Can last up to 18 months
Tips for Refrigerating Raw Peanuts:
- Still use an airtight container: Even in the fridge, it’s best to protect your peanuts. Jars or resealable bags work well.
- Double-check the freezer option: Your peanut packaging likely has specifics on whether the nuts are suitable for freezing.
Freezing Raw Peanuts: For the Long Haul
Need them to last even longer? Freezing your raw peanuts is a fantastic solution.
- Shelled and unshelled peanuts: They can both last around 2 years if frozen properly.
Freezing the Right Way:
- Airtight is still a must: Freezer bags designed for long-term storage are preferable.
- Portion them out: Freeze peanuts in smaller batches so you only thaw what you need.

Safety Considerations
While peanuts are a delicious and nutritious food, it’s important to be aware of potential food safety concerns.
