My children love it on a slice of keto bread or with a cup of yogurt. If you combine it with some Greek yogurt, you get seriously delicious low carb and sugar free dessert.

Sugar free blueberry jam is delicious with low carb pancakes and waffles. Children love that combination!

How to make sugar free blueberry jam

I use grass fed beef gelatin in this recipe and it works fine. I know that you don’t even have to use any thickener here. You can just reduce the jam by cooking it.

Don’t overcook your jam. Cook it until you like the thickness.

When checking the thickness, try cold plate test. You need to put a plate in there fridge when you start your jam cooking. When you think it’s thick enough, you may put a spoon full of jam on that cold plate. If it’s thickening on the plate, it’s done!

  • Lemon juice 1 TBS
  • Cinnamon 1/2 tsp
  • Vanilla 1 tsp
  • Grass fed beef gelatin 1.5 tsp + water 2 TBS



Prepare gelatin. Put 1.5 tsp of gelatin in a small cup with 2 TBS of water and leave it aside as you cook the jam.


Put frozen or fresh blueberries with erythritol or another low carb sweetener, vanilla, cinnamon and lemon juice in a large saucepan on a high heat and cook it until blueberries release the juice and start boiling.


When start boiling, reduce the heat to medium high and stir every few minutes.


Cook for 15 - 20 minutes or until it's reduced as you like it. If you want to use it as a spread for your bread you may reduce it more.


If you want to use it for cakes or eat with yogurt, it doesn't have to be very thick.


When it's reduced enough, remove jam from the heat, add gelatin that soaked up the water and stir until it's nicely combined.


Pour the jam into a clean jar and keep it air tight in the fridge.
