Peanut butter is a good survival food because it’s calorie-dense, high in protein and fat, and ready to eat without cooking or refrigeration. Unopened commercial peanut butter lasts up to 2 years, while natural peanut butter lasts a few months in the pantry and much longer in the fridge or freezer. For long-term storage, peanut flour and powdered peanut butter can last up to 5 years. Here’s a chart comparing the different types of peanut butter and some creative uses.
Peanut butter has been a staple in my food storage pantry for as long as I’ve been storing food. In fact, when I went on my first shopping trip to start my emergency food storage pantry, several jars of peanut butter were in my cart. It stays fresh for years, doesn’t need a stove or electricity, and a good-sized spoonful can hold off hunger pangs until dinner is ready.
The question I get most often is whether peanut butter is a good survival food and whether it holds up for long-term storage. A regular jar lasts longer than you would think, but it won’t sit on the shelf for 25 years like wheat or rice. Below, I’ll walk you through how long each kind lasts and how to store it so it doesn’t go rancid on you.

Is Peanut Butter a Good Survival Food?
Yes. Peanut butter is calorie-dense and high in protein and healthy fats, and you can eat it straight from the jar with no cooking or refrigeration. Unopened commercial peanut butter lasts up to 2 years, and powdered peanut butter can last up to 5 years.
Why I Keep Peanut Butter in My Emergency Pantry
Two tablespoons have about 190 calories and 7 to 8 grams of protein. When you’re trying to feed a family through an emergency, those calories count, and having enough food in your food storage starts with foods like this. Read more about how to make sure you’re storing enough calories so your food storage pantry will meet the nutritional needs of everyone in your family.
Peanut butter is ready to eat and satiating. There’s no stove or can opener involved, which is why I keep a few squeeze packs into our emergency kits. The protein and fat make it a stick-to-your-ribs food, and in a crisis, a familiar food that keeps everyone full for a few hours is a gift. Canned goods and beans cover the basics, but peanut butter is one of my go-to comfort foods, because a PB&J feels normal when nothing else does.
And one thing you may not have thought of, it’s a good fit for pregnant moms. Peanut butter has folate, so it’s a solid nutritional choice when you’re planning survival food for both mama and preborn baby.
Regardless of how many people you’re storing for or where you’ll keep it, it comes in just about every size, from single-serve packets to family-size tubs to powdered #10 cans. Each one of those has a place in your food storage plans and your everyday pantry.
How Long Does Peanut Butter Last?
| Type | Unopened, pantry | Opened, pantry | Opened, fridge |
|---|---|---|---|
| Conventional jarred (stabilized) | up to 2 years (check the best-by date) | 2–3 months | Up to 9 months |
| Natural (peanuts and salt only) | Several months | About 1 month | Up to 6 months |
| Powdered, small jar or pouch | About 12–18 months | Follow the label | Not needed |
| Powdered, #10 can | Up to 5 years | Follow the label | Not needed |
Most jars carry a best-by date 18 to 24 months out, and that date tells you when the quality starts to slip. A sealed jar stored somewhere cool is often fine well past it if it looks and smells normal.
Honestly, though? I’ve had opened jars of peanut butter in my pantry for many, many months without a single issue — no rancidity, no spoilage. Many other people have told me the same. So, why does peanut butter have an exceptionally long shelf life?
Why Peanut Butter Lasts So Long
Peanut butter has almost no water in it, and bacteria need water to grow. What limits its shelf life is the oil, which slowly turns rancid once oxygen gets to it. That’s why a sealed jar stored somewhere cool and dark can stay good for years after the date on the lid.
One of my readers opened a jar of natural peanut butter nearly three years past its best-by date and said it tasted just like a new jar. If you’re stocking up for the long haul, choose peanut butter stabilized with hydrogenated oil or made from high-oleic peanuts, since both resist going rancid longer than natural peanut butter.
The Best Peanut Butter for Long-Term Storage
I buy natural peanut butter, just peanuts and salt. My motto is, “When in doubt, buy whatever food has the fewest ingredients.”
However, if you’re thinking about long-term storage, say more than 6 months or so, you might want to stock up on a supply of “stabilized” peanuut butter. These have a small amount of hydrogenated oil or palm oil added so the jar doesn’t separate and lasts longer on the shelf. Natural peanut butter has a shorter shelf life, so I store it a little differently.
For my everyday pantry, I keep a few jars of natural peanut butter and rotate them. Unopened jars go in the coolest, darkest spot I have, and extra jars go in the freezer, where they keep much longer. And, here’s a trick I learned — instead of the messy job of stiring the oil with the peanut butter to combine them, just store the jar upside down and the two will gradually combine on ther own. Once a jar is open, I keep it in the fridge.
For long-term storage, another option is peanut flour and powdered peanut butter. They last years instead of months because most of the oil has been pressed out, and the oil is what goes rancid. Peanut flour is only peanuts, while most powdered peanut butter has added sugar and salt, so read the label. If you already store freeze-dried food, the storage conditions are similar — cool, dark,dry location for the longest shelf-life.
Individual squeeze packs are handy for bug-out bags and car kits, but check them when you check the rest of your kit. Heat shortens their life fast. And, these come in a variety of nut flavors if someone has a peanut allergy or just prefers almond or cashew butters.

How I Use Peanut Flour and Peanut Butter Powder
Years ago, my daughter and I started keeping peanut flour in the pantry, mostly to add more protein to our smoothies. She also mixes it with water and a little stevia to make a high-protein, no-sugar spread for apple slices.
Peanut flour is made from roasted peanuts that are ground into a paste, then pressed to remove most of the fat. The darker the roast, the stronger the peanut flavor. What’s left is high in protein, with minerals like magnesium and potassium, and it’s naturally sugar-free and low in carbs. Peanut butter powder is made the same way, but most brands add sugar and salt, so check the label if you’re watching either one.
To make a spread from either one, start with about 2 parts powder to 1 part water, stir, and add more water a little at a time until it’s the texture you like.
Beyond spreads, there are lots of ways to use it:
- Whisk it into soups or sauces as a thickener.
- Swap it in for some of the flour in pancakes or muffins.
- Sprinkle it over your morning oatmeal.
- Use it in place of peanut butter in salad dressings and marinades when you want the flavor without the fat.
Our chocolate peanut butter smoothie: Blend 1 cup almond milk, 1 teaspoon vanilla, 2 tablespoons unsweetened cocoa, 1 to 2 tablespoons peanut flour, a scoop of protein powder, and sweetener to taste. Once it’s smooth, add about 2 cups of ice and blend again until it’s thick and creamy.
How to Store Peanut Butter Long Term
- Keep unopened jars somewhere cool, dark, and dry. Heat and oxygen are two of the six enemies of food storage, and a hot garage or the cabinet above the stove will turn the oils rancid much faster.
- Rotate your stock by putting new jars in the back and using the oldest ones first. Here are more of my rules for food storage.
- Store natural peanut butter upside down so the oil doesn’t pool on top, and refrigerate it once it’s open.
- Buy jar sizes your family will finish within 2 to 3 months of opening.
- If you have more natural peanut butter than you can use, freeze it. It keeps for about 6 months in the freezer.
- For powdered peanut butter, keep the can sealed until you need it. Once it’s open, repackage the powder into jars with a fresh oxygen absorber if you won’t use it quickly.
Creative Uses for Peanut Butter
Breakfast: Stir a spoonful into oatmeal with a drizzle of honey or a dollop of yogurt for extra protein and flavor.
Snacks: Spread it on crackers, bananas, apples, or celery, or pair it with jam or fresh, local honey
Baking: Flourless peanut butter cookies are amazing and gluten-free, and a scoop of peanut butter improves brownies, pancakes, and just about any quick bread.
Birds and pets: Spread a bit on a pine cone to feed the birds in winter. Dogs love it too, at least the ones I know, who will steal a peanut butter sandwich right off a plate. If your dog loves PB and the vet approves, put a couple of pouches in your pet evacuation kit.
Pest control: It’s the best bait there is for mouse traps when you need to protect your home and food from pests and rodents.
Frequently Asked Questions
Homemade peanut butter has no stabilizers, so treat it like natural peanut butter. Keep it in the fridge and use it within about a month. For really long-term storage, say 5 years or more. powdered peanut butter or peanut flour is a better fit, and you can mix up a spread whenever you need it (see how I use them above).
Sunflower seed butter is the most common substitute, and it stores much like peanut butter. Almond butter works too if tree nuts aren’t a problem.
Yes. The texture might be a little grainier after it thaws, but a quick stir should fix that. Freezing works best for natural peanut butter.
It’s shelf-stable, so it doesn’t need refrigeration before you open it, but it won’t last indefinitely. Eventually, the oils go rancid over time, which is why rotation matters.
Usually, if it’s been stored well and hasn’t been opened. The date is about quality. Open the jar and smell it. If it smells bitter or like old paint, it’s rancid.
Not for long. Peanut butter has plenty of calories, fat, and protein, but it’s missing nutrients like vitamin C, and eating nothing else would wear on your body and your stomach.

Final Thoughts
Peanut butter is one of the easiest foods to stock, and one my family will always eat. Keep a few jars in your everyday pantry, rotate them, and add a can or two of powdered peanut butter or peanut flour for the long haul. Next time you’re at the store, grab an extra jar.

All natural peanut butter which has to be stirred does get harder and more consolidated as it ages. Much harder to stir.
The price of PB is about to skyrocket. Get it now which it's (relatively) cheap!
I LOL when Kroger sent me a bundle of store coupons….one of them was for a FREE 18 oz. jar of their peanut butter. It was like hitting a small lottery! HA!
11. All you really need to enjoy peanut butter is a finger <del>spoon.</del>
Fixed It For You
I volunteer at a food pantry and peanut butter goes in every box each month I hope this will still continue to happen as the price sores. I know that some of the recipants are elderly and the peanut butter makes a great lunch for them, no cooking. I see on the board at the pantry December pantry is going to give almond butter wonder how that compares in nutrituation???
Your site has helped me a lot in getting ready for whatever their is to come, thanks a lot for your help.

I would not put natural peanut butter in your long-term food storage. I tried it, and it gets hard and difficult to stir the oils back into the paste. Even though we eat natural peanut butter regularly, I would buy some commercial brand (Skippy, Jif, etc.) to put in long-term food storage. Since it won't get rotated like other foods, I would just donate it to the food bank every so often.
I just bought 6 of the larger size peanut butter jars for almost the same price as the smaller ones. Probably fewer people buy those big ones as they are harder to stir and were left from before the price increase.
in a bugout or no power situation it is wonderful spread on a granolla bar or a poptart~ very filling!
I was at the market today and WOW have the prices on pb gone up!!!! The 16 ounce jar of Skippy that was $2.99 in Sept is now $4.99. I do live in a rural area with only a few stores, so our prices are higher then other places. Glad I stocked up, now I need to look for coupons.
We have a good supply of peanut butter. My husband loves the stuff. We've also invested in peanut butter powder.
Great source of protein.
Would you consider Nutella a good alternative to PB as a long term storage item?
I would consider Nutella a good alternative to AIR, if I could breathe it!!! It has a fairly decent shelf life but won't be as versatile as peanut butter. I haven't stocked up on it, but only because it's too hard to resist!
A wholesale Cash and Carry in my area (NorCal) has it in a 35# pail for about $57. Going up to over $80 soon though.
Peanut butter=good
Chocolate=good
Peanut butter and chocolate=manna from heaven
Sams still has "reasonable" prices on their 2 packs of Jif…we stock up 2 or 3 at a time when we go…..
Skippy Natural has good ingredients, but doesn't need to be stirred like the other natural peanut butters.
How long does peanut butter last past its expiration if its kept in a cool, dry space, out of light and unopened?
All natural peanut butter has a lower shelf life than the stuff with hydrogenated oil, but I've not actual seen expiration dates on a jar only sell by dates. typically it looks like natural PB has about a 1yo sell by date and the other stuff has around a 2yo sell date. So for prep purposes you could probably double that or more as sell by dates are usually pretty conservative.
Also if you want to store the natural and keep it from getting hard I recommend flipping it. if it is stored top up for months all the oil rises to the top, but if you flip it over every few weeks the oil will stay mixed better as it seeks the top of the butter again. storing it in the fridge after it is opened and mixed up will also keep it from separating.
I’ve only had pb go bad once. It smells rancid when it’s bad… It was a bulk box of pb that I got from my local salvage grocery so who knows how old it was when I bought it. The portion I didn’t get transfered to jars took about three years – with the inner bag unsealed but tucked in – to go bad in my house. This stuff has an incredible shelf life. For storage purposes I’d prefer whole in the shell raw peanuts. better storage in Ma’s own wrappers And I live in a long enough growing season area to grow my own and perpetuate my supply. Think fifty pounds per person would do?
i get PB for 10/$20 at smiths. they are normally $2.50/jar but go on sale sometimes – buy 10 get 50 cents off per jar.
it’s the good stuff too. peanuts and salt. no sugar or fake oils.
i’ve never had any go bad.
Natural peanut butter does have a lot of oil and is hard to stir at first—-just stir up one time until it is mixed up and then store it in the frig. It does have oil and can go bad if heat is an issue. It will stay stirred up and easy to use has long as is cold.
Hearing some of those prices now I am glad I stocked up when the base Commissary had their case lot sale. I got the large jars of Jif smooth and crunchy for just under $3 each and had coupons for $1 off 2 so for $2.50 a jar I bought lots of it. We use a lot of it when we get a hankering. I even eat it by the spoonful out of the jar. I know the lead food person at my local Big Lots and when they had a bunch of Planters PB Chocolate Cherry go out of date I went and nabbed it for free. IAW the FDA website it should be good for up to 5 years past the sell by date.
Only one problem. Peanut allergies. A member of my fam has them. So I buy almond butter for him. It’s more expensive, though. But I am glad it is becoming more readily available.
We all love Nutella, but surely it doesn’t have the same high protein as peanut butter, does it?
Everything I recommend has to be customized to each individual’s and family’s needs.
I just wish one of the food storage companies would make almond butter powder for those of us with peanut allergies!!!
Jan, that is an excellent suggestion! I’ll pass it on to my contacts at a couple of food storage companies.
I love this article about storing peanut butter. Who doesn’t love homemade whole wheat bread with peanut butter and jelly on it? Yummy!
I have to stock up because my hubby is a peanut butter holic! Haha I Love the pb powder for smoothies.
I’ll have to lay in a Stock with my other supplies… I have some close associates who love it…
Years ago PB came in glass jars. Now in plastic jars. Will the plastic unopened jars have the same shelf life ? Is the plastic safe ?
I’m already doing a lot of the things you teach but would love to learn more. You seem to good knowledge. I have only been following you for a little while, so please excuse my ignorance. Do you know a lot about wild edible plants, their food value and medicinal use? I would love to learn about that also. Thank you. Maria
We love peanut butter and always have lots of jars. In fact, getting down to just six or eight jars makes us nervous, and it’s time to start watching for a sale so we can stock up again. It’s a cheap, simple, nutritious food.
I know this will sound dumb but can you freeze peanut butter?
I refrigerate mine after opening to lengthen the time before it goes rancid. I would just buy a small cheap jar and try freezing for a month or so, then open it.
Yes. I use it for candy making and baking. Never used it for sandwiches, I have fresh jars in my pantry. I bought a 5 pound can for baking one year, froze the surplus.

I just now (5/18) opened a clear glass jar of Natural Creamy Peanut Butter- composed of ONLY peanuts and salt (26 Oz Smuckers) purchased (7/14), dated best if used by( 6/15), and having been stored inside a totally dark 8×18 utility trailer with air conditioner controlled so as no to exceed 70 deg F in the summer ,but dropping well below freezing in the winter (I live in PA). I poured off the top layer of oil and found it not to be rancid as expected- and in fact it tasted fine. After mixing the remaining pb I found it to be indistinguishable from any newly purchased jar. I was unexpectedly very happy with the results since I have been harboring reservations from more negative projections I have seen on numerous web sites.
