This Keto Strawberry Jam is delicious on just about everything. It is really easy to make homemade sugar free strawberry jam. It takes about ten minutes and four ingredients. When fresh strawberries are in season and abundant it is worth it to make your own gluten free strawberry jam. Only 3 net carb per 3 tablespoons!
If you're on the keto diet, finding tasty and healthy alternatives to your favorite meals and snacks can be a challenge. One of the most difficult things to give up is sugar-laden jams and jellies, which are often loaded with carbs and artificial sweeteners. Fortunately, there's a simple solution: make your own sugar-free strawberry jam at home!
This easy recipe uses fresh strawberries, natural sweeteners like stevia or erythritol, and a touch of lemon juice for tartness. It's perfect for spreading on toast or adding to yogurt or oatmeal for a burst of fruity flavor without any extra calories or carbs.
I have a huge love affair with strawberries. I could eat one of the costco sized containers all by myself. Really. I like them fresh, in desserts, in jams, in salsa, and even roasted. My husband and I just tried making smoked strawberries for the first time as well. Making a low carb strawberry jam without sugar was a necessity! This sugar free keto jam recipe is also low carb, grain-free, dairy-free, and Trim Healthy Mama friendly (as a fuel pull).
Ingredients
Strawberries - Choose brightly colored berries without blemishes.
Sweetener - To make no sugar strawberry jam I do add some sweetener. Most strawberries need a bit to enhance their natural sweetness. I use a blend of granular sweeteners and stevia but you can also use monk fruit or another sweetener of your choice.
Lemon Juice - Lemon juice will add a bit of tartness that balances the sweetness of the jam nicely.
Thickener - You can use either xanthan gum or glucomannan. I do not use pectin in my jam recipes although you can use it if you prefer.
How to Make Keto Strawberry Jam
Making homemade jam is very easy! You need to cook the berries to soften them and release the natural juices, sweeten them, and then thicken it to a jam consistency. This can be made in no time!
Step One: Hull the berries and add to a medium saucepan.
Step Two: Give the strawberries a couple of good smashings with a potato masher. Just to get the juices flowing.
Step Three: Cook until they become liquidy. After cooking and before chilling the jam will look like the photo below.
Step Four: Transfer to glass jars and refrigerate until thick.
Variations
Blueberries & Raspberries - You may sub blueberries or raspberries for the strawberries. You can even use a combination of berries to make a mixed berry jam.
Frozen Strawberries - This recipe does work using frozen strawberries instead of fresh ones if they are not in season. Just make sure whatever berries you choose are flavorful.
Other Fruits - Other fruits such as peaches, plums, and apricots may be a bit too high in carbs for a low carb diet but if you just need a sugar-free jam recipe you can feel free to use any fruit you like.
Flavorings - You can add a couple of drops of vanilla extract to boost the flavor of the jam. Other great choices are lemon zest for a stronger lemon flavor or another citrus zest like orange zest or lime zest. Adding fresh herbs is also a unique variation. Basil goes very well with strawberries as does fresh thyme.
Common Questions
How to prep strawberries for jam
The hardest part of this recipe is hulling the strawberries. I use a tiny paring knife, insert it a bit off-center near the stem, and then turn the berry. The stem and hull come off all as one. The reason I suggest removing the hulls is that they are normally firm and flavorless.
Do I need to cook the jam?
Yes, this is a cooked jam. Just cook the berries over medium heat until they are softened. Smash until no large pieces remain. Add the sweetener, lemon juice, and thickener. Transfer the sugar free strawberry jam into jars. Store in the fridge and enjoy. Serve with low carb bread, keto almond flour chaffles or waffles, yogurt, cottage cheese, coconut flour muffins, keto ice cream, or just about anything.
If you don't want to cook this jam you can puree the ingredients with ground chia seeds instead since they have natural thickening properties.
How to Use Keto Strawberry Jam
I have enjoyed this easy keto strawberry jam with so many keto recipes. Everything from keto bread, waffles, coffee cake, and directly from the jar with a spoon. I still need to try it on top of vanilla ice cream and with shortbread cookies. I also like it with Greek yogurt and cottage cheese.
It's great on my Almond Flour Chaffles! Or on this Paleo And Keto Angel Food Cake. For a really special treat put a little on top of this no-bake strawberry cheesecake or use this to fill some keto pop tarts!
How to Store Low Carb Strawberry Jam
You can refrigerate this for up to 2 months or freeze it like a freezer jam for up to 6 months.
Is Strawberry Jam Sugar Free?
Most store-bought strawberry jams will have added sugar. Some do have added fruit juice instead of added sugar but unfortunately, those are not low carb keto friendly either.
Can I Can Sugar Free Strawberry Jam?
I have not tried canning it so that it is shelf-stable but I have had readers use traditional canning methods successfully. I find that even when making jam in larger batches my kids eat it fast enough there isn't any left to can.
Make sure to check out these tips on washing and storing strawberries. And, I hope you enjoy this low carb sugar free jam!

Emily says
Love this recipe, I added more lemon and it turned out great. Question though, how is there only 2g of sugar? Is that counting the natural sugars in strawberries? Thanks!
Taryn says
That is for one serving which equals 2 oz of strawberries before cooking. Strawberries have one gram of natural sugar per ounce.
Cindy says
If you want a very intense strawberry taste and naturally sweeter but also include sweetner is roasting your strawberries on parchment paper on a cookie tray...at about 400F till they soften then transfer to a pot using other ingredients to finish....i learned this ages ago what a difference...great for making strawberry icecream to

Christina says
Can I use trivia and how much? Thank You
Taryn says
Yes, Truvia should work. You would use the same amount.
Teresa says
How many pints of strawberries does it take to make the 2 pounds?
Taryn says
It would be 4 pints (blueberries are normally in this size) but strawberries are more commonly sold in 1 pound containers.
Laura says
Can you use pectin instead as a thickener?
Taryn says
I have not tried but don't why it wouldn't work.
Janica says
Is there an alternative for the glucomannan? I’m not sure what it is or where to get it.
Taryn says
Hi Janica,
It is a thickening agent. You can easily find it online. I order from Amazon. You can sub in another thickener of your choice.
Leslie says
I may have missed it, but how many jars did this make?
Taryn says
Hi Leslie, this makes about 3 small half-pint jars of jam.
Sharon says
I make this a lot! I freeze it in pint jars, and when my youngest son comes to visit he takes a cooler back filled with this strawberry jam! He puts it on sugar free cheesecake! I like to eat it from the jar!
Heather says
Hi, I was going to try raspberry jam with your sugar mix and sure gel, is that what the glucomman is a thickener?
Taryn says
Yes, the glucomannan is the thickener.
Patti says
Will this recipe work for blackberries too? How long will it last in the fridge?
Taryn says
Yes. It lasts 2-3 weeks and you can freeze it.
Bonnie says
A trick for hulling the berries....use a straw. You can use the form plastic ones that come with cups or just basic ones. You just cut the tops off and plow the straw through. It comes out the other end and you just slip the hull out the end of he straw. Sooo much faster! 🙂
Lisa Reade says
Do you know if this recipe can be frozen only? I'm looking for a jam that can be canned. Thanks!
Taryn says
I have not canned jam before but I don't see why this couldn't work.
Cara says
I just made a batch of this and it is very yummy! I did have to add extra homemade gentle sweet blend as our berries are a bit sour this year. I look forward to trying it out in the morning! Thank you for sharing!
Betty Whitmer says
Have you ever made this with Blueberries instead. I'm a blueberry person or peach. I like to eat Strawberries but don't like them in a jam or jelly. 🙁
Taryn says
Not yet. Any berry should work 🙂
Betty Whitmer says
Would you please let me know if you try the blueberries. THANKS
Corrie says
any thoughts/success on freezing?
Taryn says
This freezes well 🙂
Karen says
Do you think you could freeze this? Just wondering how the consistency would be when it thaws out.
Taryn says
Yes, I have frozen it. The consistency is fine when thawed.
Tracy says
Could you make this with frozen strawberries?
Taryn says
Yes, just make sure they are ripe and sweet. 🙂
