This sugar-free strawberry jam is simple, sweetened with a little bit of honey, and doesn’t have any store-bought pectin in it. We add some chia seeds for texture, taste, and to help the jam thicken. This is a great healthier substitute to traditional jams. You can use this recipe with other fruit as well.


I’ve been wanting to try a sugar-free jam for a while now and finally got around to make a batch. I’ll be honest and say that I kinda have a problem with the idea… When I think about jam I think sweet, sticky goodness and no matter how sweet the fruit is, or how much honey you add, it never as sweet as when you use good ol’ sugar.

I never make jam with the traditional ratio of 1:1 between sugar and fruit anyway. If I use 2 lb of fruit, I’ll add 1lb of sugar. Most of the time I stick to that ratio like I show in this recipe for my low sugar strawberry jam.

So I was already making jams with less sugar, but I really wanted to try a sugar-free version too.

Since I was going to make a healthier jam, I decided to add some chia seeds to the mix as well. They add a crunch and are very healthy for us. They also gel so in this case they do the part of pectin and gel the jam naturally.

A side note here… Instead of buying pectin at the store, I use lemon seeds in my jams (if I don’t add chia seeds). Lemon seeds have natural pectin in them. If you’d like to see how I usually make my jams, without pectin and less sugar, check out this Peach Jam Recipe.

It all started when I noticed these strawberries…

I mean, look at them… How can you leave these in the store on a cold shelf?

I couldn’t, so I got 6 lb of them.

2 pounds were gobbled up with no mercy whatsoever on the way home by my three little termites. Another 2 pounds turned into a strawberry shortcake (can’t go wrong there), and the last 2 pounds participated in the sugar-free jam experiment.

Another side note… I have since then planted a 100ft plus of strawberries with the hopes of making many delicious strawberry desserts every spring. But the termites I was talking about above (now there are four of them!) won’t let one, One, ONE strawberry in the house!

So I still get most of my strawberries for jams and desserts at the grocery store or from a local farm. I have to go shopping without the kids, smuggle the strawberries into the house in the dark and hide them in the fridge behind a pile of other things until I can get to them.

It’s quite the operation, I tell you. But it’s worth it.

Ok, back to the jam now…

After I removed the tops and cut them into pieces, I was left with 1lb 10oz of fruit.

And to the party joined half  a cup of honey. I turned the heat to medium-high…

And let the berries cook for a few minutes. The heat will make them lose some juice and soften. I let it come to a boil and left it at this stage for a couple of minutes before lowering the heat to between medium and low. I kept cooking the strawberries for about 20 minutes or so at this temperature stirring frequently.

At this point the strawberries were completely soft. I used a potato masher to mash the strawberries and then let them gently cook for another 10 minutes.

During those 10 minutes, I fished out some of the foam from the sides of the pot and stirred every couple of minutes. The foam doesn’t bother me too much so I don’t go crazy trying to get it all, just the majority of it.

I also added about 1 teaspoon of fresh lemon juice to the jam.

The jam is almost ready so it’s time to prepare the jars. I prepare my jars in the oven instead of in a water bath… Much easier in my opinion.

Canning Low Sugar Strawberry Jam…

Even though I didn't use sugar I was surprised to find out that it was plenty sweet enough for us. This is a basic recipe that you can use with other berries too. I hope you'd like it!  #sugarfreestrawberryjam

Here is how you do this: heat the oven to 320F, place your jars without the lids on a baking sheet and stick them in the oven for 10 minutes. At the same time fill a small pot with water, place your new lids and rings (rings don’t have to be new) in there and let the pot boil gently for a few minutes.

Do this about ten minutes before your jam is ready, so your jars and jam are ready approximately at the same time and you can transfer the hot jam into the hot jars (keeping similar temperatures will prevent cracks in the jars).

OK, so after 30 minutes or so, the jam was starting to thicken but not quite there yet. At this point, I added 3 tablespoons of chia seeds and mixed them in…

A couple of minutes later the jam was thick enough. It takes some practice to learn when a jam is ready, but after making jams a couple of times you’ll know to recognize this stage. When you move the jam around in the pot with a spatula, you can feel it’s thick and there is not too much liquid flowing around.

At this time my jars were ready so I filled them with the jam (make sure to leave about 1/2 inch headspace). This is a small batch. It made 2 half-pint jars.

I covered them with the clean lids and bands (not too tight), then placed them upside down on a kitchen towel on the counter. They both sealed within a couple of hours. I let them completely cool overnight and then removed the ring and placed them in the pantry.

We had a little bit of leftover in the pot that I used to make cookies with, it was a great cookie filling (read: Thumbprint Cookies Recipe).

Obviously, this jam is not as sweet as a jam that has a load of sugar in it but it tastes great in my opinion, even the kids had no problem with the lack of sugar.

Notes About This Sugar Free Strawberry Jam…

Can I use other fruit? I think you can definitely use other berries. I’ve never tried it with other kinds of fruit but I am sure that the same recipe will work with other berries.

Someone was asking if they can use frozen berries. I think it’s possible, the only thing that I notice about frozen fruit is that when you cook them they seem to have more liquid than fresh fruit so you might need to cook it a bit longer to get rid of the excess liquid.

Can I double or triple the recipe? You sure can!

Preserving this sugar-free strawberry jam… You probably notice that I didn’t process the jars in a water bath… Turning the jars upside down is an old method of sealing jars and I find it to work wonderfully, however “trusted sources” that are not grandma say it’s not a safe way to preserve food. It’s up to you to decide which way to go but just know that you can process the jars in a water bath as well.

If you prefer, you can also freeze this jam. It should last a long time in the freezer!

How long will the jam last at room temperature? Since there is no sugar in this jam I don’t think it will last as long as regular jam. After my jars sealed I placed them in the pantry and tried to keep them so I can see how long the jam last. After four months we couldn’t wait any longer and opened and ate the last jar. It was still great.

Make sure you remove the rings before you store your jars and once in a while check that nothing funky is happening in the jar. Like I said above, I believe it will last longer in the freezer so you can go this route if you want to keep it for a long time but four months were good enough for me.

    1. I don’t have the exact time… If the jars seal, I think it should last just like a regular jam, up to a year in the pantry. If you have a jar that didn’t seal, place it in the fridge and use it first.

    1. I never tried but it sounds good. You can definitely give it a try, just take into consideration that ground flax seed won’t have the same jelling effect like the chia so you might need to add pectin. Look up my peach jam recipe, I show there how to use lemon seeds for their natural pectin instead of using the pectin you buy at the store.Let me know how it turned out.

    1. I didn’t do a hot water bath for those. We are just finishing the last can and the taste is great but it has only been a couple of months since I made it.

  1. I started my “Ever Bearing” strawberries with 6 plants 6 years ago. Now I supply each neighbor with a free “flat” of strawberries (About 7 flats go out) and still have enough to make what my husband & I consume in a year. This year I decided to make juice. Breakfast at our house requires juice. You can’t buy in any store the quality of homemade juice and berry juice is awesome! The first batches are a mix of strawberry, blueberry, Jostaberry & Raspberry and then the next batches included Marionberry as they ripened and now the batches are including blackberry. We can’t eat all the jam from last year (we had a great year in 2015) but we sure can put-down the juice! It’s easy to include the juice in smoothies when winter sets in for that taste of summer.

      1. I do use a juicer but not for making “clear” berry blends. It makes it “too pulpy” and my husband doesn’t enjoy that. There are several berries that make a better juice when heated, that would be Marionberry, Jostaberry (a gooseberry/current cross), blueberry and blackberry, heat brings out the flavor. One reason I make a lot of clear juice and can it up for winter usage is because I don’t have a food storage freezer. We tossed the idea around several times but decided to put our money into more canning and shelf storage than running a freezer.

  2. What would be a good substitute for the honey? I follow the South Beach diet and honey is a no no. I do use Splenda. Would that work?

    1. Amber, I never used Splenda so I am not sure. Maybe agave? You will have to experiment and see how it turns out. Let me know. I’ll also ask on my Facebook page and see if someone else has a suggestion.

  3. Hello,
    I made this recipe last night and it turned out great however only 2 of my 18 jars sealed properly. 16 of them I could still push down the lid and make it “pop”. Do you have any tips on what I can do to reseal these 16 jars? I know I could do the whole process over again but I’m just wondering if there is a quicker way now that the jars are already filled with jam?
    Thank you! 🙂
    Lindsay

    1. Oh, Lindsay, sorry I didn’t see this sooner.
      I believe that once the jam cooled there is nothing else to do. If you do it again try to turn the jars over so after you fill them and close them with the lid, turn them so they stand on the lid, this sometimes helps with sealing.
      What did you end up doing?

    2. I used to do preserves with my Grandma growing up. If her jams or jellies didn’t seal she would use paragon wax to seal the top.

  4. No problem! I actually ended up just putting them in my canner and boiling them. Then I left them out on a tea towel on the counter and everyone of them ended up sealing properly! I boiled all my jars (without jam) and boiled the jam when I was making it so I knew that everything was sterilized properly. I noticed the first time that they weren’t sealing properly right away so I put them all in the fridge and used my canner method not even 24hours later. With them sitting in the fridge I figured it was unlikely that any bacteria would develop that quickly so I took my chances by not taking the jam out of the jars and starting the whole process again! Other than this issue though the jam turned out wonderfully and has a very nice flavor!

  5. This jam looks delicious and I may try it with Splenda. Honey is no different from sugar. THAT is a myth and it definitely isn’t diabetic friendly. If you want peanut butter that is healthy get the kind with no sugar added. It’s usually called natural and you have to stir it and then keep it in the fridge. Some people get freaked out when they see the peanut oil on top, forgetting that the other kind of peanut butter has hydrogenated oil mixed in and is much less healthy. 🙂

  6. I don’t like to cook the strawberries in freezer jam, because I think using fresh strawberries makes it taste so well…fresh! Would this recipe work if I just used fresh smashed strawberries and added the honey and chia seeds or does it have to be cooked first?

    1. I’ve tried doubling the recipe and it did come out the same; just as delicious! I did need to switch my mix into a wide-mouth pan rather than my stock pot because the liquid didn’t evaporate quite as quickly as the single batch. It needed to be a thinner layer in a wider pan rather than piled on, if that makes sense.

  7. Hey there, found this recipe and decided to use it. I doubled it and very happy! This is the first time at making any type of jam and also canning or jarring so I’m absolutely thrilled! My daughter is in FFA which is Future Farmers of America and has been in it for years. She sells strawberry’s for them and I bought two whole flats for a wonderful price. 4 pounds of them yielded 6 1/2 pint jars and I’ve got more to do tomorrow. Thank you so much for sharing this recipe! We love it!

    Much respect and thanks,
    Nichole from Linden VA

    1. Oh, I am so happy. I plan on making it again once strawberries are ready for harvest here.
      Thanks for taking the time to leave a comment!

  8. I heard that it is not good to can chia seeds, but there hasn’t been any experience with it that I can find. I’m just wondering how long your jam lasted with the chia seeds when you canned it? I don’t want to waste a whole year’s supply if it’s going to go bad. Thanks!

    1. It was a long time ago and I can’t remember exactly but I believe we used this jam within a couple of months (maybe 3 or 4…). So I can’t tell you for sure what will happen after a year but it was good for a few months.

    1. I never tried… You might need to cook them a little longer to get rid of some of the access liquid but I think it can work.

  9. Hi Lady Lee,

    I just waindering if you heard about honey becomes toxic when it’s boiled and what are your opinion on this.

    I’ve used your recipe once and it was probably best jam I’ve ever made. But then I found out that boiling honey produces toxic effect and I am quite concerned.

    At the moment I am just doing little search to find out if it’s only the myth or maybe the truth… hoping it’s not true. Looking forward knowing what are your thoughts are on this.

    Cheers,
    Nara

    1. I’ve never heard of it becoming toxic if boiled but I am a member of the local beekeepers association and I bet I can find someone there who will have an answer for me.
      I always wonder how things were done in the past… I bet it was harder for them to make white sugar than harvest honey from beehives… So, did they use the honey for jams? Didn’t make jams at all? Or was there a different solution?
      For example, a few weeks ago I wrote about canning milk. I found out that modern research states that you should NOT can milk at home… Still, people have been doing this for generations, you know…
      Honestly, I usually take modern research with a grain of salt and check how things have been done in the past.
      This is interesting… I’ll have to check and get back to you.
      Let me know if you find anything.
      Thanks for taking the time to write this and I am so happy you enjoyed the jam!

  10. Can you make this recipe with blackberries? I tried this recipe with strawberries and its fabulous so I wanted to try it with other fruit.

    1. It’s on my list of things to do this summer to try it with blueberries. The only thing is that blueberries might not be as sweet as strawberries but other than that I think it should work. If you try, please let me know how you liked it. I’m glad that you liked the recipe!

      1. I tried it with blackberries and raspberries and it was amazing!!! I have found this recipe is pretty versatile with different fruits so far!

  11. Will this jam thicken without the chia seeds? I will make this and I keep all my canned jams and jellys with the rings on in the pantry for a year. They also have pectin

    1. If you want it to thicken but you don’t want to use the chia seeds you can use store bought pectin or you can add a few lemon seeds 15 minutes before the jam is done. Lemon seeds have natural pectin in them and will help the jam thicken. I show how to do this in my Peach Jam recipe. Just search the blog for peach jam and you’ll find it.

    1. Usually, if something funky and wrong like mold, for example, is developing inside the jars when they are in storage it develops on the top. If I remove the rings I am able to see much better what’s going on inside the jar on the top of the food.
      If I spot something that doesn’t look right, I’ll open the jar, scoop the top out and toss it and refrigerate the jar. This way, if I caught it in time, I don’t lose the whole thing.
      You don’t have to do it, just easier to monitor what’s going on in there without the ring. Also, you can use the rings again when canning something else.

  12. I find if you add 1 teaspoon of butter to the jam it doesn’t foam at all!

    Thanks for the great recipe! Hope my Nan and Pop love it!

  13. I wanted to make marmalade but didn’t want to use sugar. Honey makes wonderful marmalade, orange, mandarin , or lemon mixed with orange. You don’t need pectin as the fruit adds it.
    Have never tried strawberry jam as the fruit doesn’t last long enough! Will try it now.

    1. It’s easier to monitor what’s going on inside the jar if the ring is not there. Also, you can reuse your rings to can something else. Once the jar is sealed there is no use for the ring anymore.

  14. I can’t use honey for a sugar substitute. Do you think using Stevia or a low calorie sweetener would work just as well??

    Thx

    1. I think that it would. Maybe the cooking time will change but I heard of people making jam with stevia before. Also, I am not sure if you can can it if you use stevia. I’ve never done it before. If you want to preserve it you might need to do some research about that.
