If you're looking for a very quick and easy raspberry sauce to make, you will love this one!
Deliciously frozen raspberries, a little lemon juice, water and Swerve, that's it! You don't need any gelatin or Xanthan Gum to thicken it and that's the real beauty of this recipe!
There is nothing more gorgeous than fresh berries when they are in season, but if you're like me, I love raspberries throughout the year.
So, I chose to use frozen raspberries in this recipe. Plus, I just love the consistency and the lovely juice that they produce when you thaw them out.
Though this sauce only uses a few simple ingredients, the French have a really fancy name for it. It's also called a raspberry coulis! It is defined as a thick sauce.
What's in Keto Raspberry Sauce
- Raspberries
- Swerve confectioners
- Lemon juice
- Water
*Exact measurements are listed in the recipe card below.
How to Make Low Carb Raspberry Sauce
Add the raspberries, Swerve, lemon juice and water to a sauce pan and cook over medium heat for 8-10 minutes.
The berries will break down and the sauce will thicken as it cooks.
Allow to cool before serving.
At this point, you can either strain the seeds out, puree in the food processor or leave it chunky.
I decided to leave the sauce chunky for my Mini Cheesecakes recipe, but I pureed it to use in my No-Bake Chocolate Raspberry Tart.
Depending on what you're using it with, you might prefer a less chunky sauce. You can puree it in a food processor for an even smoother consistency.
How Do I Store Sugar Free Raspberry Sauce?
This raspberry Keto sauce will keep for up to 5 days in the fridge in an airtight container. If you would like to make this in advance or make extra for later, you can freeze it for several months.
Are Raspberries Keto?
Raspberries are one of the best fruits to enjoy on a Low Carb or Keto diet. Strawberries, blackberries, cranberries and blueberries all have lower carbs and sugar than other fruits and can be eaten in moderation without being kicked out of Ketosis.
What are the Carb in Raspberries?
Raspberries are probably considered the best berry on Keto. They're nutrient dense and with only 6.7 net carbs in one whole cup of raspberries, the possibilities of ways to use them are endless.
Can I Make this Sauce with Other Berries?
Of course you can! Most all berries are an acceptable lower carb option on Keto as compared to other fruits. Feel free to make this with sauce with blueberries, blackberries or strawberries.
Enjoy this raspberry sauce chunky style, over my Mini Cheesecakes!
Or puree it to use in my No-Bake Chocolate Raspberry Tart.

Hello. How long does this sugar free raspberry sauce last in the fridge? Thank you.
Keto Cooking Christian
Within the recipe, storage recommendations are listed. You can keep it in the fridge for about 5 days or freeze it.
Karen Swaffield
What is the size of one serving?
Keto Cooking Christian
It's 1/8th of the recipe, I'm sorry I don't have it measured in tablespoons.
Sam
Question why confection sugar and not granulated?
Keto Cooking Christian
Granular tends to recrystalize once it cools and I find the confectioners doesn't do that.

If you want to store the sauce in the freezer, do you use a bag or a plastic container? Also how do you unfreeze it, just let it thaw or can you also warm it up?
Keto Cooking Christian
I prefer to use glass that is freezer safe, but plastic will work too. When I am ready to use it, I try to allow it to thaw in the fridge overnight.
Melissa Vernon
Can you used fresh berries
Keto Cooking Christian
Sure you can, but you might have to add a little more liquid.
Rachel
Would this recipe work well paired with duck? Or would it be a touch too sweet? Also, I was planning on serving it warm. Thoughts?
Keto Cooking Christian
I've never tried it that way before, but serving it warm should work fine.
Pearl
Hi there, is it possible to make this recipe without any sweetener? Thanks!!!
Keto Cooking Christian
Sure, if you'd like to leave it out you can. I can't promise the sauce will be quite the same, but you can try it.
Barbara
I made the sauce as a topping for my keto pancakes made from a powdered mix. So good!!! For how long can I leave the leftovers on the fridge?
Keto Cooking Christian
At least 3-5 days in an airtight container should be just fine. Glad you enjoyed the sauce!
Julia
Is this something you are able to can the same way you might regular jams and sauces?
Keto Cooking Christian
I've never made enough to can, so I can't say for sure. But you can freeze leftovers, if that helps!
Debra
I can this blueberry sauce. I double the recipe. I put the sauce in half pint sterilized jars. I leave a 1/2 in headspace. Put on lid and rings and water bath for 20 minutes. Put the jars on a towel on the counter and let sit till next morning. I remove the rings and wash the jars. Dry and put rings back on. I’ve done this for 2 years now and it does great.
Lisa Reesor
Tured our great! I use it on my "otmeal", with yogurt and on cheesecake.
Keto Cooking Christian
So nice to hear that you liked it! Thanks for letting me know 🙂
Bethany
Could you make this into jelly/jam to go on 90 sec Keto bread?
Keto Cooking Christian
Sure you could! You can use either about 1/4 - 1/2 teaspoon of Xanthan Gum or a tablespoon of grass-fed beef gelatin (has no flavor) to thicken it. The Xanthan Gum will thicken up right away and you definitely don't want to use too much or it will get slimey, so I'd start with 1/4 teaspoon and see how it goes. If you use the grass-fed beef gelatin, that will thicken as it cools, but typically 1 tablespoon is enough to thicken it to that jam like consistency. I hope that helps!
