How To Preserve Pecans And Other Nuts In Mason Jars


I preserve pecans in Mason canning jars. I was lucky enough to receive 6 quarts of Georgia Pecans from my daughter who lives there. These nuts have been processed. In other words, shelled, halved, and cleaned. They arrived a couple of days ago, and I was thrilled because I use a LOT of pecans during the holidays. I got them in time to make my pecan pies for Thanksgiving Day dinner. As you can see by my photos they are very plump, beautiful pecans. They would have cost a small fortune in the grocery store!

The first time I heard of baking a cake in a jar I couldn’t believe that would work, but it does. If you are short on freezer space, you can use this method. Mason jar canning is not just for jams, jellies, and pickles. If you want to send someone a nice home cooked meal, cook it and send it by priority mail preserved in a sealed Mason jar.

I do want to make it clear this method should NOT be used in the place of canning food. It's safe to cook food thoroughly, and then seal it in a jar.

These jars can be successfully mailed if they are packed well with bubble wrap. Mason Jars are manufactured in several sizes. I used 1 quart jars for this project. When I bake a cake in a jar, I use the half pint size because the cake cooks more evenly. The size of the jar will depend on the food you are preparing to preserve.


  1. Sterilize the jars and lids by boiling them for about 10 minutes to sterilize them. Turn them upside down to dry. If you have a large pot, you can sterilize several jars at once.
  2. Fill the jars with the pecans, leaving about an inch from the top of the jar. Place the jar in the microwave for 2 minutes. This is done to heat the jar, not to cook the nuts.
  3. As soon as you take the jars out of the microwave, place the top and lid on the jar. Tighten. Listen for the “pop” sound that lets you know the jar is properly sealed. The jar has to be HOT before it will seal.
  4. Enjoy your nuts later, or give them as a gift!

Step One: Boiling The Jar


Step Two and Three: Ready To Fill The Jars With Pecans


Step Three: The Filled Jars Are Sealed


If You Are Skeptical, Just Try It!

If you are like me, you will be skeptical of this method. For all you skeptics all I can say is, try it!

Never thought of canning nuts! I bet they retain their texture much better than freezing. Another great idea. Voted up and useful. Thanks, Mary!

Hi oceansnsunsets! Thanks for reading. I do hope you'll try this method of preserving food. I was really thrilled to get these pecans after having to buy some from the grocery store about a month ago. Goodnight.

Hey, The Dirt Farmer. Good to see you. You are right, when you open the jar they are better than if they had been frozen. I've started preserving a lot of food now in Mason Jars. My freezer got too full of meats, etc.

What a neat way to store nuts, Mary. Do squirrels know about your unique canning methods? It would make their job of storing supplies for the winter so much easier.

Oh, drbj, only you would think of the squirrels needing a place to store their nuts! You are SO funny! You could write a pun on that! Goodnight.

We have gotten so far away from the times where food was preserved in jars. You are helping us conserve food. In a society of waste and excess this is vital information. I will try your tips and hints. Thanks Mary.

Great tips! This is the country for canning, Everyone cans everything here from cucumbers, to pickles, tomatoes, berries, mushrooms etc. This way a lot of people especially in the country get through the winter.

Hi Gypsy Rose Lee, It's great that you people preserve food. We Americans are SO spoiled. We need to get back to the basics of living off the earth. We are also very wasteful of our resources, I think. Thanks for reading, see you again, soon.

I love canning things, but had never thought of a microwave technique. I wonder what else could be canned safely using the microwave??? Interesting! Voted up!

mary615 profile image

mary615 5 years ago from Florida Author

Hi pharmacist, I only put the jars in the microwave to heat them so I get a good seal. I wouldn't try to actually can foods using the microwave. I don't think it would be safe. This only works for food products that doesn't have to be sterilized.

Thanks for reading. Thanks for the Vote UP

I look forward to following you!

Could I do this also with dry rice and beans to help them keep longer?

mary615 profile image

mary615 4 years ago from Florida Author

Gee, coriena, I honestly don't know. I'm wondering why you want to preserve rice and beans (dried beans?) then they pretty much keep on their own, don't they? You could experient and see what happens. Thanks for the question, sorry I wasn't much help. Thanks for reading and commenting.

Hi Mary,

I would never have thought to preserve nuts in this fashion. We still have a big old chest freezer and simply freeze our nuts until they are needed for baking or eating. But this is good to know for people who do not have excess freezer space. Up votes and will try to share. Tweeted!

What a really cool idea, thanks for sharing. My wife keeps all nuts in mason jars but we don't have any trees but if we did you can bet they'd be put in Mason jars.

mary615 4 years ago from Florida Author

Hi, Peggy W. I like to freeze nuts, too, but I have no room left in mine. So, I find this method of preserving nuts in Mason jars to be perfect for me. Since I have learned to preserve cooked meals in Mason jars, I enjoy doing that, too. I learned to do that when I learned how to make a cake in a jar. (wrote a Hub about that, too)

Thanks so much for the votes, the tweet and the share. Mary

Hi Fiddleman, thank for reading and taking the time to comment on how to preserve pecans in Mason jars.

North Carolina is a great place to grow Pecans, isn't it?? I know N. Georgia sure is.

Goodnight, Mary

Hi, RTalloni, Well, I'm just so glad you learned how to preserve Pecans in Mason jars today! It is a good idea if you don't have room in the freezer (which I don't).

Thanks for reading, Mary

Hi, Joyce. I'm so glad you will try to preserve pecans in Mason Jars. I use this method to preserve lot of things. I make a cake in a jar that you might enjoy reading about, too. I just opened my last jar of pecans from Georgia, and I will miss them.

Mary, I must say that you are truly a fine cook. I am going to start preserving some of of tese pecans and share this hub too.

mary615 profile image

mary615 3 years ago from Florida Author

Good Morning, midget38. I just used the last of my Georgia pecans yesterday. Hope my daughter from Georgia sends me some more. They are so expensive in the grocery stores. That's why I preserve them when I have them!

Thanks so much for the share, Mary

Well heck. That is so simple. I can't believe I never thought of it. I've been freezing them in bags and they take up tons of space! Thanks for the great idea!

mary615 profile image

mary615 3 years ago from Florida Author

Hi, Sharkye11. Yes, I used to freeze nuts until I discovered this method of preserving them in Mason Jars. I just opened my last jar (from 2011), and they were still like freshly shelled.

I'm glad you like my idea, and hope you will try.

This is an excellent idea, and too, will free up my freezer space. Your pecans look $10.00 a pound that is a fortune. I also

received about 2/12 pounds fresh country pecans last week and I have some left to can in a jar. Thank you for this great tip.

mary615 profile image

mary615 3 years ago from Florida Author

Hi, frogyfish. Yes, this is such a wonderful way to preserve those expensive pecans. I just used the last of mine for pies at Christmas. I do hope someone from Georgia will send me some more.

I think you will be pleased at the results of preserving pecans in a Mason jar. Just follow my instructions, and you can't go wrong.

So nice to see you again, Mary

Hi, Mike Robbers. Yes, this is a great way to preserve any kind of nuts. Now I just wish my daughter would send me some more pecans from Georgia! I'm all out.

Thanks so much for the votes and the share, I appreciate that, Mary

Hazel2248 3 years ago

Mary, I so enjoyed reading your HubPages, can you tell me how to

get this page other than google search as I'd like to send it to my

family, they would love to can as I have done all of my life. Thank you

mary615 profile image

mary615 3 years ago from Florida Author

Hi Hazel 2248. Thanks for reading and for your interest in my Hubs. If you go to then search Mary615. That will take you to my profile with my Hubs to share with your family.

I have found this method works very well to preserve so many different types of food. At Christmas I made Caramel Corn to present in a Mason Jar. I wrote a Hub about that, too.

Thanks again, Mary

Joyce 3 years ago

I did it! They all sealed so far, however I do have moisure in my jars.

Will that cause a storage problem?

mary615 profile image

mary615 3 years ago from Florida Author

Hi Joyce. As long as the jars are sealed, the nuts will be fine. They may have had some moisture in them naturally. I'm happy you tried my method of preserving nuts!

Carol 3 years ago

It's easier for me to just use a jar sealer for the food saver. It removes all the air and there's no moisture in the jar.

mary615 profile image

mary615 3 years ago from Florida Author

Hi Carol. How nice of you to read my article and leave a comment!

Happy Easter, Mary

Linda 3 years ago

I noticed you have "Moisture" in your jars, will that go away? If not will that moisture cause your pecans to mold? I just pressure canned 9 pints and they sealed ok, but they did have some moisture in the jars. Is that going to be a problem?

mary615 profile image

mary615 3 years ago from Florida Author

Hi Linda. I have never had my pecans to mold. As long they sealed properly, you should not have any problems.

Thanks for reading and commenting, Mary

Would this work with candied pecans? I'm a little afraid to microwave the already cooked pecans. I know it states it's not to cook the pecans but I'm afraid it will cook them anyway. :/ I just don't want to burn or overcook what I have made.

mary615 profile image

mary615 24 months ago from Florida Author

Hi, Aiden. The only reason you put the filled jars into the microwave for a couple of minutes is to just get the jar hot so it will seal properly. I don't think you would "cook" your nuts more. I wouldn't go any longer than two minues, though.

Regan 15 months ago

Would using the Food Saver jar attachment work as well?

mary615 profile image

mary615 15 months ago from Florida Author

Hi, Regan. I am not familiar with the Food Saver jar attachment; sorry. As long as you get a good seal. I'll have to research this food saver jar. Thanks for reading my article, Mary

jenna 11 months ago

this is wonderful because i was afraid of doing this. someone told me the nuts go rancid because of oil. i saw your comment where you kept them for over a year and now I am back in : )

Linda l 10 months ago

How long do they keep this way if family doesn't it all in one week?
