Easy Sugar Free Lemon Sorbet

There’s nothing quite as refreshing as a sugar free sorbet! This lemon sorbet is perfectly sweet, zingy and wonderfully refreshing, but without all the sugar of a normal sorbet. A great Keto dessert for a hot day.

I do love a portion of creamy sugar free ice cream, be it fruity or chocolatey. But sometimes only a sorbet will hit the spot.

A super easy way to make homemade sorbet is to simply blitz frozen fruit in a food processor until smooth. Should your mix become too liquid, re-freeze – otherwise serve straight away. If your fruit is naturally sweet, you don’t even need to add any additional sweetener.

If you’re watching your sugar and carb intake, you have to be mindful though and keep your portion size small. Especially tropical fruits such as mangoes and pineapple are high in natural sugars and generally avoided by people on low carb or Keto diets. For a pure-fruit sorbet, blackberries, raspberries, strawberries or watermelon are better choices. Here’s a handy infographic about carbs in fruit.

Personally, I think it’s sad to vow never to taste certain types of fruit again. And yes, I even have a banana bread on the blog that contains REAL banana and NO banana extract (and it’s still low carb, take a look!!!). Fruit is nature’s candy, so I enjoy it on occasion and in moderation.

My all time favourite sorbet flavour has got to be LEMON. I love the zingy, fresh taste and I LOOOOVE the idea that I’m getting a super-sized dose of vitamin C while eating dessert!

Lemons are low carb fruits, but despite their sour taste, they still have carbs – 6 net carbs per 100 grams, to be precise.

Obviously, there’s no way to make lemon sorbet without additional sweetener. This low-carb summer treat uses Swerve to sweeten instead of sugar so it won’t spike your blood sugar in the same way that the refined stuff will. But feel free to use granulated erythritol or even Lakanto if you prefer.

Guys, it’s SO simple to make lemon sorbet. Are you ready?

How to make sugar free sorbet – step by step: 

1.) Add the water, keto-friendly sweetener and lemon peel to a pan. Heat on a low heat until the sweetener dissolves and thickens slightly to a syrup, about 7 minutes. Leave to cool. Discard the lemon peel.

TIP: When removing the peel from the lemon ensure you don’t get any white pith. This can make the syrup bitter.

2.) Juice the lemons. Add the lemon juice to the cooled syrup and stir.

3.) Pour the lemon mix into a non-stick loaf tin (or ice cube trays), cover with cling film and freeze for 3 hours or until solid. I left mine over night.

4.) When frozen, run the sides of the loaf tin under hot water to loosen the frozen sorbet. Tip onto a chopping board and chop into chunks with a knife. If you’ve left it overnight you’ll need to give it a good smash.

5.) Place the chunks in a high speed food processor and blitz until smooth. The smaller you have cut the cubes the easier it is. You may need to scrape and blitz several times until it all combines, depending on how long you left it in the freezer.

6.) Once combined, pour the sorbet back into your loaf tin and freeze for about 1.5 – 2 hours until just scoop-able. Serve scoops of sorbet decorated with a few curls of lemon zest.

Tips and recipe variations

Make sure you choose a white low-carb sweetener or else you may end up with more of a murky colour!

If you leave your sugar free sorbet to set too much by mistake, simply repeat the step of chopping into chunks and blitzing. You can repeat this step if you don’t eat all your sorbet in one go and leave in the freezer for several weeks.

You can also make this recipe in an ice cream maker. Simply prepare the syrup and chill it in the freezer for about 30 minutes. Then pour the mix into an ice cream maker and churn as per manufacturers instructions. When the sorbet is nice and slushy, transfer it to a non stick loaf pan, cover with cling film and freeze for about 2 hours until scoop-able.
