This sauce is SO easy to make! Just dump the fruit and some sweetener into a slow cooker – and let it go to work! Here are some ways to use this sauce:
- Over vanilla ice cream (low carb store-bought brands I love are Breyer's CarbSmart, HaloTop and Arctic Zero)
- In a crepe
- Over low carb waffles
- As a layer in a breakfast parfait with nuts and Greek yogurt – see my recipe here!
- You could even add it to your favorite protein smoothie!
How to Make Low Carb Berry Sauce
To make the sauce I added fresh blueberries, blackberries and strawberries to a slow cooker. I have a small 3 quart slow cooker which is perfect for this sauce but I've also used the slow cooker function on my Instant Pot. Oh and I hulled the strawberries with my trusty strawberry huller! If you don't have one, I highly recommend them! They ARE uni-taskers, but they're small, inexpensive and work so well!
I also added a splash of water and some low carb sweetener – use whichever one you prefer! I used Lakanto and you can get 20% off anything in their store if you use coupon code SAFTC!
I cooked the sauce on low heat for around 3 hours (use the slow cooker function on the Instant Pot). Towards the end of the cooking time I sprinkled over a pinch of xanthan gum. This makes the sauce slightly more jam-like, without adding taste or carbs. It is totally optional though, as it depends on what consistency of sauce you prefer.
Note: The cooking process can drain some of the color from the strawberries. If you like, you may want to add a few drops of red food dye to restore the color.
Let the sauce cool then spoon it into a jar or suitable storage container. Store in the fridge until required.

Your berry sauce sounds just delicious. I bet it’s wonderful with a waffle and some cream. You could probably even use it as jam on some low carb bread!
