You’d never guess this is a keto jam recipe! It has all of the flavor or regular jam, without the added sugar and carbs. This sugar free strawberry jam is thickened with chia seeds, which gives it great texture as well as a nutrition boost. And best of all, you can make this chia seed jam with just TWO ingredients (plus a couple of optional ones).
I served this keto strawberry jam on 90 second bread, but any kind would be delicious. (Plus, I have more serving ideas for you at the bottom of this post.) If you prefer jelly over jam, try making keto jelly instead.
You can easily make this an unsweetened jam recipe if your berries are sweet enough, but I almost always add powdered Besti to mine. It tastes like sugar, dissolves effortlessly, and doesn’t crystallize when you store your jam (unlike other sweeteners).
What Is Chia Seed Jam?
Chia jam is a jam recipe that is thickened with chia seeds instead of other thickeners, like sugar or pectin. The seeds make it naturally jammy and also adds plenty of nutrition to jam that’s normally mostly sugar.
Why You’ll Love This Keto Jam Recipe

Sugar Free Jam Ingredients
This section explains how to choose the best ingredients for sugar free strawberry jam, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
- Strawberries – Fresh strawberries are easiest to use because they can be sliced, but you can also use frozen sliced or chopped strawberries. Or feel free to make your keto jam raspberry, blueberry, or blackberry instead by swapping in those berries. (Did you know: Strawberries are keto, but all berries are on the list of keto fruit!)
- Chia seeds – They will help to thicken your keto jam, instead of sugar or pectin. Plus, they add a boost of nutrition.
- Besti Powdered Monk Fruit Allulose Blend – Sweetener is optional, but recommended if you like a sweet jam. This is my go-to sweetener for jams because it’s natural, tastes like sugar, and won’t crystallize in the fridge… which is important since you’re unlikely to eat all the jam at once. You could also use powdered allulose for the same consistency, but might need a bit more of it. Powdered erythritol and most other sweetener brands are a last resort substitute, as they do tend to crystallize.
- Lemon zest – This is also optional, but helps bring out sweet, bright flavor in the berries.

How To Make Sugar Free Strawberry Jam
This section shows how to make sugar free jam with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Heat strawberries. Place strawberries in a saucepan over medium heat. Cook, stirring occasionally, for about 10 minutes, until strawberries release liquid and soften.
- Mash. Use a spoon or potato masher to mash berries.
TIP: Blend if you prefer a smoother jam. If you don’t want berry pieces in your jam, puree with an immersion blender (or in a regular blender) at this step.


- Adjust sweetness. Check to see if jam is sweet enough. If it isn’t sweet enough for you, add sweetener to taste, 1 tablespoon at a time.
- Thicken. Stir in chia seeds and lemon zest. Allow jam to cool to thicken.
TIP: Add more chia seeds for thicker jam. If you like your jam extra thick, add a couple additional teaspoons of chia seeds to reach the consistency you like. Keep in mind that the jam will continue to thicken when you refrigerate it.

0Dearest Maya, I just felt the need to say THANK YOU for turning me into a cooking junkie. All fun aside, this jam is JAMMING! I used blackberries instead of strawberries and its sooooo goood!! Its very simple and quick to make. Cant wait to try it out tomorrow after it has had time to sit in the fridge. I started with 4 stars so walked back to have another taste and changed it to 5 stars. Thanks again!!
Lisa koolsbergen
0To store do you have to sterilize the container or is it ok to put in a jar with lid after cooled? Really enjoyed the recipe
Thank you
Wholesome Yum D
0Hi Lisa, If you are storing it in the refrigerator, you wouldn’t need to sterilize it.
Jane King
0I have made this several times and loved it each and every time. My drawback is it disappears soooo quickly.
Patricia DeMuth
0Made this jam and it’s really good, definitely needs some sweetener tho, but it thickened up really well!!! So happy.
TJ
0This was excellent and so easy. To make it even easier I didn’t bother slicing the strawberries. Instead I removed the tops then put them in the food processor. I pulsed them a bit until they were in small pieces. This made it so much easier. I didn’t have to slice and I didn’t have much mashing to do once they started cooking. I also got a smooth result without having to use an immersion blender. I highly recommend this recipe! Thank you.
Tami Pacumio
0Can this recipe be water bath canned for longer shelf stability?
Wholesome Yum D
0Hi Tami, I have never done that but I think it should work for you.
Holly L.
0I make this all the time. I do strawberry and raspberry and it’s so good. Very simple to make. I don’t use sweetener or lemon just berries and chia seeds.
Leslie
0I freeze it in ice cube trays or small chocolate molds. Then store in a Mason jar for easy portions. Delicious! Thanks for all your recipes and products!
Tara Howard
0This recipe is a life saver!! It seems like most prepared Keto friendly sweet sauces are not pleasing for my palette. I bought the ChocZero Strawberry Jam and can’t stomach the aftertaste (my sister used to use Sweet & Low as a Sweetner so she does not find the taste intolerable – so the jam did not go to waste). Every sweet recipe of yours that I have tried thus far is EXCELLENT and I am not sure if it is the Besties Sweetners that make them wonderful or the ability to tailor the amount of sweetness, BUT I LOVE this jam. I just had the batch I made last night on my Yeast Keto White Bread (again your recipe) and it is MARVELOUS. Thank you so much for making this lifestyle change liveable!❤️❤️
Pye
0Hi Maya. Has anyone ever canned the strawberry jam? If so, how did it turn out?
Wholesome Yum D
0Hi Pye, I have never attempted to can this jam.
Cheryl
0Hi, if this was stored in the freezer to get longer shelf life up to the 3 mths, when taken out to use do you have to unthaw the whole thing for one time use, or can it be unthawed a little to use what you desire then put back in the freezer? I know typically foods shouldn’t be re-froze so just wondering.
Wholesome Yum D
0Hi Cheryl, I haven’t tried that, but don’t usually recommend thawing and re-freezing foods.
Leslie
0I freeze it in ice cube trays or small chocolate molds. Then store in a Mason jar for easy portions. Delicious! Thanks for all your recipes and products!
Char
0This recipe was a hit with my church weight loss group Daniel Plan. Easy, Fun, Delicious, Economical and Nutritious too! Have you priced Sugar Free Jams?? Thank you!
Wholesome Yum D
0Hi Char, I am happy to hear you and your church group enjoyed the jam!
Barbara
0This recipe was so easy and super delicious.. next I’m trying raspberries!!!
Kristyn
0Love the chia seeds in this jam! My family loves it & I love that it’s sugar-free! We will be using it on tons of things!
Natalie
0Amazing jam!! We love this on toast! I will be stocking up!
Amy L Huntley
0Homemade Jam is the absolute best and I love that this is sugar free too! You can’t even tell that it is sugar free.
Claudia Thibodeau
0How would you make apple jelly ??
Wholesome Yum M
0Hi Claudia, As far as I understand, apples need a sugar or packaged pectin to create a jelly. Apple jelly is very high in sugar all on their own, so it wouldn’t fit into a keto or low carb lifestyle.
Shannon
0How long can this be stored before it goes bad??
Wholesome Yum M
0Hi Shannon, This jam will keep for about a week in the fridge. You can move it to the freezer if you need. It will be good for about 3 months when properly stored.
Max
0Can I use psyllium husk instead of chia seeds?
Wholesome Yum D
0Hi Max, I have never tried that, so I don’t know how it would work. If you try it, please let me know the results.
Leslie Ellins
0I love all your recipes. You make me think Keto “outside the box”. Thanks so much!
I tried this last weekend and was thrilled with the finished product. It was even better after it sat in the fridge a few days. The strawberry flavour just seemed to POP after sitting a bit. Paired with your English Muffin recipe it was awesome!
I have made them 6 at a time and baked in those muffin top silicon molds. I have never tried them in the microwave, but I am sure they would work as all your recipes are fabulous. I purchased a one year subscription to your Easy Keto app just so I could have easy access to your recipes.
YASMIN NAIK
0I made this with stawberries and bluberries, since I didn’t have enough. It turned out delicious. I substituted a 1/4 tsp of Xanthum gum instead of chia ( I have a chia pudding almost everyday). I spread it on my plain keto cheese cake, sublime from plain lol.
Chelsea Wilhelm-Maskis
0How long will this keep in the fridge?
Wholesome Yum M
0Hi Chelsea, This jam is best in the fridge for a week, but you can also freeze it for up to three months.
Laurie
0IS THERE ANTHING I CAN USE INSTEAD LEOMON ZEST IF NOT WHERE CAN I FIND IT, EXACTLY WHAT IS IT?
Wholesome Yum M
0Hi Laurie, Lemon zest is the outside yellow peel from the lemon. You can use a small grater or microplane to extract your own zest from a lemon, just be sure to only use the yellow skin and not the white pith underneath the skin. The pith is very bitter and can overpower the recipe.
Elizabeth
0Is it possible to strain this as I don’t care for the seeds sticking n my teeth?
Wholesome Yum M
0Hi Elizabeth, Yes, absolutely! You’ll want to use a blender to puree the berries, then you can push them through a sieve to remove the seeds. Enjoy!
Denise
0Has anybody tried this using ground chia seeds? I detest that chia seeds stick in my teeth but would love to get a Keto-Friendly jam just don’t want the whole seeds
Denise
Wholesome Yum M
0Hi Denise, Yes, you can use ground chia seeds.
Nancy Wright
0I think this sounds great! Looking forward to trying this summer with homegrown strawberries and blueberries too. Thanks so much!
Yadira
0Made it very easy and very yummy; perfect with my keto toast!! Thank you so much for the recipe!
Brianna
0This is just what I was looking for! Thanks for all the great recipes 🙂
A couple questions – Do you think this recipe could be canned, like sealed in the jars and stored on the shelf, since it’s cooked?
I usually make Freezer jam for the year when I go strawberry picking- is there a reason it would only last 3 months?
Thanks!
Wholesome Yum M
0Hi Brianna, Chia seed jams are not safe for canning. There are a couple of resources online that can explain why in more detail, but basically it has to do with the ability for seeds to grow certain strains of bacteria even after being canned. This jam is best within 3 months in the freezer, any longer and it may get freezer burn. If you have a chest freezer, you may be able to get a longer freeze time out of this recipe. I hope this helps!
Brianna
0Good to know, thanks for your response!
Sarah G
0Very easy to make, one question tho. How long can it be stored? Is it best in the fridge or counter top?
Wholesome Yum M
0Hi Sarah, Please store your jam in the fridge. It is best for up to a week in the fridge or 3 months in the freezer. Enjoy!
Sherry Richter
0Just wondering if the chia seeds can be ground for smoother jam?
Wholesome Yum M
0Hi Sherry, Yes that should work fine.
Lori
0I’m a bit of a freezer jam freak due to not using sugar but other sweeteners. I don’t mind seeds from berries and vary using ground chia seeds, pectin or gelatin to thicken. I just made an apple pie freezer jam with gelatin (half batch) from another site, swapping out the sugar for an erythritol blend. I noticed Wholesome Yum’s keto apple pie has no apples and the apple muffins have one diced apple in the whole batch thus needing extract to carry the flavor – that’s it for apples. Adding a refrigerator-jam/freezer-jam page, including strawberry/chia, to be spread on the keto bread of one’s choice would allow folks to have many flavor profiles they may be missing or think they can no longer have. Particularly seasonal fruits for which the serving size must be kept to a minimum so that a tablespoon works out just fine. So more jams, please?
Wholesome Yum M
0Hi Lori, Thanks for the great suggestion!
Patricia Ballek
0Made this last week yummy.
Elizabeth
0This is so yummy! I make this every week. It is great in yogurt or porridge. I also use a variety of frozen berries. It is great during the winter months or any time I year.
Jaimie
0I just made this today and am in LOVE! It is SO GOOD! This is the first time in 4 months on veto that I’ve had strawberry jam. Now I’m going to want it on everything! Its as so easy, too!
Zuzana
0This is so quick and easy. I never make any jams. Have to change that
Yang
0Perfect for the strawberry season coming! I am saving this to make soon.
Kari
0There’s nothing like homemade jam, and I’m so excited to try your sugar free version! Also super excited that it freezes well so I can make big batches!
Guy
0Love how simple this is! There’s really no need to add sugar when you use fresh strawberries so I can’t wait to make this summer!
Renee D Kohley
0Such a fun way to use seasonal strawberries! We will pick them locally end of June here so I can’t wait to make some jam!
Raia Todd
0Love how easy chia seed jam is! It’s nice to have an option that doesn’t included added sweeteners, too.
Jean
0Yum, I loooove chia jams and this was fantastic!
Josianne Plante
0Simple and so good!! I used organic strawberries added a bit of stevia. It was perfect
Paula
0Have you tried using blueberries or raspberries? I assume they would work as well?
Maya | Wholesome Yum
0Hi Paula, Yes, you can use other berries, too!
Pam
0Can you use flax seeds instead of chia seeds?
Wholesome Yum A
0I think so, Pam! Let me know if you try it.
Margaret Kennedy
0Thank you so much for this recipe, been trying to find one.
Also very interesting to know that Chia seeds are a good thickener.
Sarah
0Can this be made with ground chia seeds? My husband loves jam but seeds are painful and he avoids anything that might have seeds.
Maya | Wholesome Yum
0Hi Sarah, Yes, you can use ground seeds if you like! Or puree the jam after it’s ready.
Dee
0Can you use lemon juice instead of the zest and get the same results?
Wholesome Yum D
0Hi Dee, Yes, you could use lemon juice.
