Try this easy sugar-free cranberry sauce recipe for your next holiday feast. You need only 3 ingredients and it is ready in 10 minutes.

There is something wonderfully comforting about festive food. I love the ritual of eating the same trusted and tested meals during the holiday season.
Our festive menu is set in stone - a mix of German, British and Caribbean representing the origins and heritage of our family. Then there are the highlights leading up to the big feast - such as gingerbread cupcakes, this spiced chocolate torte, low carb christmas stollen, gluten free panettone and of course my German cinnamon stars.
And whether you are celebrating Thanksgiving or Christmas or both, at some point cranberry sauce will make an appearance.
In my opinion, homemade cranberry sauce tastes so much better than the sugary sauce you can buy in the shops.
This keto cranberry sauce is SUPER TASTY and contains only the natural sugars occurring in the cranberries.
I am serving it every year as a side dish to my Low Carb Keto Turkey. I also use a variety of this sauce in my Keto Cranberry Streusel Bars.
You can make your own sugar free cranberry sauce with only 3 ingredients (plus water). In fact, it is SO SIMPLE you can hardly call it a recipe.

Ingredients
Here are the ingredients you'll need:
Cranberries. These can be fresh cranberries or frozen. There is no need to thaw frozen cranberries first, just use them straight from the freezer.
Sweetener. I used powdered Bocha Sweet in the recipe. I like it because it has no aftertaste. However, any sweetener works. Just make sure it is a powdered version, such as powdered erythritol, monk fruit sweetener, xylitol or allulose.
Brandy. This is optional, but gives the sauce a festive flavor.
Water
Instructions
(This section contains step by step instructions and photos that show how to make this recipe. Find the recipe card with ingredient amounts and nutritional information at the bottom of the post.)

Step 1: Put the frozen or fresh cranberries in a saucepan with the other ingredients.

Step 2: Stir and bring the mixture to the boil. Then reduce to a medium heat and let the sauce cook until the berries begin to pop.
Top tip
The pectin in the fruit helps the sauce thicken all on its own. There is no need to add xanthan gum or other thickeners.
The sauce thickens further once it cools down. It should still be a little runny when you take it off the stove.
Variations
Below are ideas how you can change up the flavor:
Basic. Use only cranberries, powdered sweetener and water.
Cinnamon. Add a cinnamon stick into the saucepan or add 1 teaspoon of cinnamon. Nutmeg, ginger and a tiny pinch of cloves would also work well here.
Orange. Regular cranberry sauce is made with orange juice. For a low carb cranberry sauce, add 1 tablespoon of grated orange zest instead. You could also add a squeeze of lemon juice. This will give the same flavor without the carbs.
Vanilla. Another alternative to the brandy. 1 teaspoon of vanilla extract will lend a warming note.

FAQ
I have made this sugar free cranberry sauce with powdered erythritol and also with powdered Bocha Sweet. Basically, any 1:1 sugar substitute works, as long as it is powdered. Granulated erythritol will re-crystallise as it cools, which means you'll end up with crunchy bits in the sauce. The exception is granulated allulose, which does not re-crystallise.
Yes. Use 2 teaspoons of stevia glycerite, which is equivalent to 1 cup of sugar.
Absolutely. Cranberry sauce keeps in the fridge for several weeks. In fact, I have used leftover sauce as a topping for my morning yoghurt months after I made it. The pectin in the sauce preserves it well. There is no need to freeze it.
Uses
Sugar-free cranberry sauce does not only taste great with turkey, pork, meatballs or goose.
I have used it as a topping for my coconut flour pancakes and my keto pancakes.
It is also delicious with sugar free cheesecake and served warm over sugar free ice cream or this Keto Rice Pudding.
If you let the mix simmer on the stove for a little longer, it reduces enough to make a delicious cranberry jam. Then you can spread it over toasted and buttered low carb bread.

I made this without the brandy but it came out super tart. I tried adding more powdered erythritol but it changed nothing. Did I overcook or was it the cranberries? I've never bought fresh cranberries before so.....Thanks for the recipes! (as a side note, after refrigerating the sauce, there is a hard surface maybe too much erythritol formed on top. I'm using it in my morning smoothies so as not to waste them, and it works!
Katrin Nürnberger
Hi Denise, it sound like you have had a batch of cranberries that were extra tart?
Merja
Best cranberry sauce by far! Good enough to eat with a spoon!!
John loggen
Just starting on low carb journey all great recipes send more
Pam Bjornson
I love cranberry sauce but since I have not been able to tolerate cane sugar and have replaced it with monkfruit no one wants to eat the cranberry sauce because the monkfruit solidifies so I will try some powdered sugar or some liquid Stevia and hope myself and everyone else likes it this Christmas.
Katrin Nürnberger
You can also get allulose. This tastes much better than stevia in my opinion and it does not recrystallise at all.
Attila
Hello,
Does the 10-minute cooking time apply to frozen or fresh? Or is it the same for both?
Do I need to defrost the frozen berries first?
Thanks.
Katrin Nürnberger
You don't need to defrost the berries. Frozen berries will need a couple minutes longer. Although it should also depend on the size of the berries. Simply cook until it's nice and thick.
Attila
Thanks!
I made it from frozen berries and roughly a good 10-11 minutes after boiling were enough. The taste is nice and it is really sweet. I think with this I'm ready for pancake day 😀
Alison Tuohey
Hi, I can only get dried cranberries. Can I use these? Thanks
Katrin Nürnberger
In theory you could, because all you'd need is to add water again. But first of all, most dried cranberries contain sugar. And also, you may not be able to get a properly juicy sauce using dried cranberries. I'd see if you can find frozen fresh cranberries somewhere. They are normally for sale all year round.
Alison Tuohey
I'm in Spain and just can't get them. I'll have a bash with dried and keep you posted. Many thanks 🙂

Excellent !!!!
Philippa
I made 2 batches, one with stevia and another with ground up erythitol. Threw the stevia version away - didn’t like the aftertaste, but the other was amazing .... I’ll be having that with yoghurt, cheese, Turkey, ham ......
Catherine
Yum! Made my first batch with orange zest. It's delicious! And perfectly sweetened, without the overload of sugar from the canned stuff. Next time, I'll make it plain. My husband is a purist! Can't wait to try this on yogurt in the morning. Thanks for another amazing recipe!
Norton Karp
The recipe sounds interesting. And I have a question; My local market doesn't carry powdered erythritol and I'm not a fan of Stevia. Can I use any other artificial sweetener like Sweet 'n Low, or Equal?
And also, how would it taste on ice cream? I've never seen cranberry flavored ice cream and I was wondering if the combination might be conflicting and cause it to be bitter. What has your experience been?
Thank you for the recipe and I look forward to making it for Thanksgiving.
Katrin
Hello, I would not recommend artificial sweeteners such as sweet'n'low or Equal. I think they're ok as a one-off, but not good for regular use. Erythritol or xylitol are sugar alternatives of natural origin and are not harmful for our bodies. If you can, get hold of erythritol, even if it's in granulated form. You can always grind it down in a food processor or with a pestle and mortar. You can order it from Amazon if you can't get it in your supermarket, or from Lakanto.
I think using it on ice cream is a GREAT idea. I have never tried it, but can imagine it would be delicious. You could make your life really simple and use a vanilla ice cream and put a cranberry swirl through it.

Erythritol granular can be made in powdered by putting it into a bullet type blend
Karen
This sauce is ah-ma-zing! I made it with whiskey because I did not have brandy. Worked a treat!
Katrin
That's good to know that other booze works well in this recipe too 🙂
Janet B
I only have stevia drops at home, which I use with my tea. Do you think I can use them for this recipe?
Katrin
You can give it a try, though I do find that erythritol has the least amount of aftertaste. If I use stevia in recipes, I tend to mix both stevia and erythritol. My stevia drops equal 4 drops = 1 tsp of sugar. Start with 16-20 drops and take it from there?
Marisa
I did not realize it was so easy to make homemade cranberry sauce! Brilliant
Katrin
And even better, it's sugar free 🙂
Janina
I've got my family coming over for Sunday lunch this weekend. I'll serve your sauce then - it sounds great
Katrin
That sounds great! What's on the menu?
GennaH
You're getting me in the mood for Christmas! This sauce looks so yummy...
Katrin
Thank you! It's ready in no time at all.
