The sugar-free raspberry jam recipe

Is strawberry jam keto?

Traditional jam is not keto. Homemade jam is also not sugar-free. Most jams and preserves are made with so much sugar which thickens the jam/jelly and acts as a natural preservative.

I have low-carb and easy keto recipes to substitute for all these. No more rocketing blood sugar here thank you.

Is chia keto?

Yes, chia is extremely low in carbs higher in protein than most seeds, and is a great way to make easy homemade chia seed jam. Chia seeds are very small (only 2 millimeters in diameter). Chia seeds are sold as white chia or black chia.

What I love about chia seeds is their neutral flavor and their ability to absorb 12 times their weight in water. This means you can make low-carb and keto recipes pretty easily without adding flour to thicken them.

Chia seeds have the most amazing ability to absorb water, thicken and swell creating a yummy thick jam. You don’t even need to cook them. This really is the easiest jam and a wonderful recipe.

No more standing over the oven cooking berries on medium heat for hours until the traditional homemade jam sets. This is an easy no-bake recipe.

What ingredients do you need?

Chia seeds jam ingredients

To make this great recipe, you only need 5 simple ingredients. Fresh fruit (your favorite berries), some fresh lemon juice, chia seeds, and your favorite sugar-free sweetener.

  • fresh berries or frozen berries
  • chia seeds
  • sweetener (sugar replacement) of choice
  • lemon juice
  • water

Typically, making jam is an all-day process. I don’t know about you, but I don’t have time for boiling, sterilizing, preserving jars, and not to mention all that sugar!

I made my own jam because I refuse to buy sugar-free jam from the supermarket. Too many companies use artificial sweeteners such as Sucralose, aspartame, or saccharin.

Or they use maltitol which raises blood sugars (try some, test your blood sugars, watch them rise and rise and rise). I prefer to use stevia, xylitol, or erythritol.

Yes, there will be a little sugar in the chia jam from the berries, but look at the comparisons below. This really is the perfect way to still eat jam and stay on your keto diet.

This sugar free jam only takes 5 minutes to make and can set in 20 minutes. It is packed with delicious high fibre chia seeds with all their plant omega-3 fatty acids.

How many carbs are there in chia seed jam?

You can make the chia jam with any berry. The sugar and carb count will vary depending on which berry you choose to use. You can see the carbs in fruits to compare which is the most keto-friendly berry.

  • Regular berry jam – per 20g tbsp = 13g carbohydrates, 13g sugars
  • Homemade chia berry jam – per 20g tbsp = 3.5g carbohydrates, 0.8g sugar

So why are chia seeds so brilliant? Chia seeds have the most amazing ability to absorb many times their size in liquid and swell and thicken. It is this property that we can harness to make a super easy chia jam and jellies.

You can vary how thick or spreadable you would like your chia jam to be. Simply add more chia seeds and watch it quickly thicken. Alternatively, add more water or berries and it will become a little more liquid in its texture.

Top tips for making chia seed jam

As you make this recipe, here are some of the most common questions people often ask about chia seed jam. Browse the list and see if your question is listed here too.

How do you make it smooth without seeds and bits?

Personally, I like to seed the little seeds from the berries I used to make the jam, but if you have picky children, why not puree it with a stick blender? You can even use a potato masher to mix the berries, seeds, lemon juice, and sweetener.

As time goes on, puree the jam less and less, because children must get used to lumpy ‘bits’ in their food.

For many children, the food they like or dislike comes down to texture. This is a tricky aspect to deal with overnight, but it can be done. For some, this may take months. So be patient and encouraging!

Some children will eat mince/ground beef, but not a steak. Then, other children will eat fruit puree, but not a piece of fruit. Some will eat tomato paste on a pizza, but not a whole tomato. If we can help encourage children even a tiny way towards accepting different textures, their food repertoire will begin to grow.

What kind of fruit can I add to the chia seed jam?

The fun thing about this jam is that you can use any type of fruit that you want. The only thing that will change is the number of natural sugars from the fruit. If you are trying to count your carbs, you’ll want to look at how much natural sugar is in the fruit before you use it.

Some of the best fruits to use in chia seed jam are:

  • Blueberry
  • Strawberry
  • Raspberry
  • Blackcurrant

Do chia seeds thicken jam?

Yes, when chia seeds mix with water, they create a natural thickener. The chia seeds also add fiber and protein to the jam too.

Is chia seed jam safe for canning?

No, chia seed jam is not safe for canning. The only safe way to use chia seeds in jam in by following my recipe, which doesn’t use any type of canning method at all.

Are fresh or frozen berries better for this recipe?

The fantastic thing about this sugar-free jam recipe is that you can use either frozen berries or fresh ones. If you are using frozen berries, let them defrost before you mash them into a puree.

Low-carb ways to use sugar-free jam

This can be used just like you would use other flavors of jelly. Here are a few ideas to get you started!

  1. That is a great tip especially to those fresh to the blogosphere.
    Short but very accurate information… Thanks for sharing this one.
    A must read article!

  2. I make this often – I mix it through plain yoghurt mostly but it’s great anywhere you’d usually have jam. It also makes a great topping for a low carb cheesecake!

    1. Denise Farr says:

      Great ideas. I will use it on top of the No Bake Lemon Cheesecake next time, and also to stir through yoghurt or cream. Easy to make. I found just half a tablespoon of stevia worked fine for us.

  3. Hey… Just wondering if you could use maple syrup as the sweetener? I can’t tolerate the natural sweeteners very well (stevia, xylitol, honey, coconut sugar), but find maple syrup is OK. Would the amount of water need to be lowered because of the chia seeds??

  4. Could I use cherries instead of berries? Or should I just try it?

  5. How long will this store in a refrigerator?

    1. I would keep it for up to a week in the fridge. Just make enough to last you that long, then make another batch each time you want to enjoy some more. It’s such a quick recipe (thank goodness), you can make it on a regular basis 🙂

  6. Could you use tomatoes. My grandmother made tomato jelly and it was my favorite!

  7. Would ground chia work as well as the whole seed? Would I use less?

  8. Pippa Loiacono says:

    My jam won’t set. What can I do?

    1. Easy peasy. Add more chia seeds. Chia seeds have the wonderful quality of soaking up more liquid. Depending on which berries you have used, and whether they have been washed, frozen etc may make the jam more liquid. Add another tablespoon of chia seeds at a time until it sets. Remember the chia seeds will take a few minutes to swell and absorb the liquid, so don’t add too much too quickly, otherwise you may have a jelly which has gone the other way, and is too solid.

  9. Nice jam, thanks for sharing, would this freeze?

    1. I have never tried, nor been asked before but I don’t see why that wouldn’t work. In fact, you could freeze individual portions in an ice cube tray! Genius!

        Do the seed part of chia seeds stay hard?
        I want to make this for my dad but he doesn’t like too many seeds because its hard on his teeth.

  10. Do you think this would work with kiwis? I have an abundant harvest and they are all ripening at once!

    1. Hmm, great question and I’m not too sure of the answer. I don’t know how the enzymes in the kiwifruit would react with the chia. In theory it should set as thew chia purely swells with the liquid, but as we know, kiwifruit will stop gelatine from setting due to the enzymes. I’d love you to come back and let me know the results. Just remember kiwifruit are quite high in sugar, but when they are in your backyard, it seems a crime not to use them 🙂

    2. So disappointed….. my jam turned out black in colour from the chia seeds and not juicy and red as your pic…. I used frozen berries so wonder did that make the difference and it was not very sweet so I will have to add a bit more sweetness. I did freeze some in little glass pots and they defrosted perfectly

  11. Could this be used with citrus to make a marmalade?

  12. Can I forgo lemon or is there something that isnt acidic to add? They cause me a lot of bladder pain ??

  13. Does this have a similar texture to Chia pudding (I hate chia pudding) or is it closer to chunky jam? I prefer smooth textures so when you talk about pureeing it for children do you mean that after adding the chia you puree it? Or is it after the jam has set? Thank you! Thinking of replacing my gluten free morning cereal with some keto choc waffles with this jam, cream and blueberries! (might not have the blueberries depending on carb content lol, gotta keep the carbs low ;p)

  14. The chia jam is sooo good that I am making a double batch today as yesterdays is gone (shared it around!). I love the way the chia seeds look like the raspberry seeds. I left my raspberries unmashed as I like the lumpy fruit. Teams well with the 3 seed bread. Thank you so much.

    Absolute winner! I just made this with black raspberries I had picked over the summer & froze. Simply fabulous & fabulously simple. Thank you!

  16. 5 stars
    If I want topp use fresh berries, do I cook them down.. cool..and smash?
    Does it freeze well?

  17. Can this chia jam be canned n sealed??

    1. I’m not a jam making expert, but I don’t think so. Canning and sealing regular jam is self-preserving because of the high sugar content, which is lacking here. I fear bacteria would grow in chia jam that has been stored for a longer time than is specified in this recipe. Luckily chia jam is quick and easy to whip up a little batch every few days.

    I used strawberries because believe this, it was the only fruit in Kroger at the time. As a jam on toast , it was good but then I had some whipped cream and folded a teaspoon (wanted to check first) of the Chia Jam in it. OMG! What a nice little treat! Felt like I was cheating with Strawberry Ice Cream. Can you freeze whipped Cream after you make it? Think I am going to try a small bowl with the jam to see how it works out.

    Hey! This is kind of off topic but I need some advice from an established
    blog. Is it hard to set up your own blog? I’m not very techincal but I can figure
    things out pretty quick. I’m thinking about making my own but I’m not sure where to start.
    Do you have any points or suggestions? Many thanks

      Spoiler alert, it takes a lot of work. Once you get to a certain point, you then need to find some amazing people to help you as there is no way you can do all of this by yourself. But it is the most fulfilling thing I have ever done. As an ex-pharmacist, knowing I have helped more people regain their health in the last 6 years using low-carb nutrition, rather than through dispensing their prescriptions, is so incredibly rewarding. Good luck Carlton 🙂

    Absolutely amazing jam, I really thought jam was a thing of the past with my new keto eating. This is fabulous and so much healthier than normal jam. Makes you wonder why we put on the fruit mixed with tonnes of sugar combo we all grow up loving! Thanks so much for sharing your recipe. V

  23. 5 stars
    Excellent! I love that I can use the amount of sweetener and lemon juice that suits me. I used frozen raspberries and ended up with about two cups. That’s way too much for me to eat in a week, but read all of the comments and found two people who had frozen it successfully.
    Thank you so much for this delicious, easy jam recipe.

      Thank you, Nancy, we love this sugar-free jam. Recently, I have been experimenting by adding some xanthan gum to make it thicker and slightly chewy. It was superb.

  24. 5 stars
    Wow I’m so excited to make this jam 😍
    one question: How long I can store the jam in the fridge?
    Thank you ☺️ 🙏
