Here's a staple for your fridge: sugar free blueberry jam! Spread on low carb bread or use it as a fruity sauce with yoghurt, pancakes or waffles.
Â
If you ask me about the one thing in our freezer that we never run out, I'd say it's frozen blueberries.We add a few to top a bowl of yoghurt or coconut flour porridge, the kids like to use them in smoothies and they give lovely little bursts of flavour in these grab and go low carb muffins.
My family finish around one bag of blueberries a week, so I have added them to my repeat supermarket delivery order.
Blueberries are high in vitamins, high in antioxidants and have a moderate amount of carbs. 100g of blueberries contain 12g of net carbs, which makes one handful of blueberries - a decent portion - an agreeable 4g net carbs. Here's a handy article by Diet Doctor if you'd like to find out more about the amount of carbs in fruit.
On top of that, frozen blueberries are rather reasonable in price. And whilst you might want to decorate your showstopper cake with fresh berries, for a normal meal the frozen berries will do nicely.
So. Jam. I stopped eating it when I went sugar free. And I missed it. That glistening dollop of fruity deliciousness on a slice of toast... history. Until I started making my raw raspberry chia jam, that is, and my favourite low carb rolls.
Here is a new addition to your low carb jam repertoire that is so ridiculously easy to make you could get your kids to do it for you: sugar free blueberry jam.
Blueberries are so sweet on their own that this jam does not even require extra sweetener. All you need to do is blueberries, lemon, some water and a couple of pinches of xanthan gum to thicken. That's it!
This jam tastes great on bread such as my Rustic Paleo Bread or these low carb English muffins (they're so simple, you make them in the microwave!). It works well as a fruity sauce on almond cream cheese pancakes or these almond butter waffles . I imagine it would also be delicious as a filling for low carb sponge cakes. Plus, you can use it as a filling in my Keto Pop Tarts.
Recipe Tip - How sweet your jam is will depend on the natural sweetness of your blueberries. If you find the jam is not sweet enough, feel free to add a teaspoon or two of powdered erythritol or 4 drops of stevia glycerite.
If you do not have xanthan gum, you can also thicken the jam with ground chia seeds. 1 teaspoon should be enough.

Recipe
Sugar Free Blueberry Jam
from Sugar Free LondonerNote: The servings slider only changes the first amount in each line and not any subsequent amounts. Please make your own calculations where necessary.
Ingredients
- 2 cups / 300g blueberries, frozen or fresh
- 2 tablespoon water
- juice of ½ lemon
- 2 pinches xanthan gum
- optional: 1 teaspoon vanilla extract
Instructions
- Put the blueberries, water and lemon juice (and vanilla, if using) in a non stick pan, cover and bring to a boil.
- Remove the lid and cook on a medium heat for ca 15 minutes, stirring regularly. The mixture will reduce by â…“ and thicken. Smash the berries with a spoon while they cook.
- You can blend the mixture if you wish to have a smooth consistency. I like it the way it is, with a few bits and pieces in it.
- At the end, take a couple of pinches xanthan gum and sprinkle it evenly into the pot, stirring well afterwards. Xanthan gum is a brilliant thickening agent and is also used in gluten free baking, so it does come in handy. You only need a tiny amount - it's quite remarkable.
- Pour the mixture into a clean jar and store in the fridge. This recipe fills a small (200ml) jar.

Hello, whay is the serving amount for this?
Katrin
Hi Meghan, I calculated 1 serving = 1 tbsp.
Leona
Can you use powdered pectin instead of gum?
Katrin
Never tried it, but that's what is normally used in jams, right? I'm sure it would work!
Meras
Have you tried adding a sweetener ?
Katrin
No, I have not. But of course you could if you like your jam sweet - a few drops of liquid stevia should do the trick. If you want to try the recipe, it's worth making it without and taste before you add more sweetness. I was so surprised at how sweet my jam was.
Elisia
Can I waterbath this to make it shelf stable for long term?
Katrin
I guess if you sterilize a jar and seal it airtight it will last longer.
Tammy
This is delicious! Do you know how longs is it's shelf life?
Katrin
If you keep it in the fridge and only stick fresh spoons/knives in it, I'd feel comfortable with a week.
Leslie
Tammy asked my question. 🙂 Katrin, ave you tried freezing it in small portions after making it? Recipe looks delicious!
Katrin
Hi Leslie, I haven't tried. But I'm sure it would work. Good idea to make a huge batch. My daughter keeps on saying we have to make it again!
Bonita
Can it be canned .?
Katrin
No, I would not do that. It contains no preservative ( real sugar acts as a preservative and extends shelf life - that's why companies love to use it in so many products). But if you fill it in a clean container and keep it in the fridge it does keep a while.
Brandi Crawford
Definitely bookmarking this! I need a sugar-free jam option.
Katrin
Awesome news Brandi. Let me know how you get on!
Linda
Can I use any fruit to make this jam? I'm diabetic and I miss eating jam on my toast or biscuits.
Katrin
Of course you can! Or make a mixed berry version. If you use raspberries only for example you might want to add a bit of extra sweetener such as xylitol or erythritol as they are more tart. Or you add a ripe pear to the mix and adjust your carb calculation.
Elaine @ Dishes Delish
I haven't made jam in a long time. But you made me want to make this blueberry jam!! It looks awesome!
Katrin
I hope you will give it a go Elaine. It makes a great fruity topping as well - I just had some with yoghurt.
Jehan Hale
This is beautiful! I've been wanting to make jams, and making it a goal for this summer!
Suzy | The Mediterranean Dish
Love that this jam is sugar free!
Katrin
Blueberries have so much sweetness on their own accord that extra sweetener really isn't necessary!
Tara
We always have frozen blueberries on hand too. I absolutely love the color of this jam. It sounds perfect for waffles.
Katrin
It works perfectly with waffles. The one thing I'd try to avoid is getting it on your clothes...
