Low-Carb Watermelon Sorbet

Pin recipeFollow us 50.3k

Summer and watermelon are almost synonyms - I can't imagine summer without fresh chilled watermelon! A couple of days ago, I asked my Facebook followers if there is any cocktail they are missing on their low-carb journey. Well, watermelon sorbet is definitely not a cocktail recipe but it's great for hot summer days and will be included in my next recipe. Stay tuned, it's coming soon! :-)

Ingredients (makes 8 servings, ~16 scoops)

Note: When looking for ingredients, try to get them in their most natural form (organic, without unnecessary additives).


  1. Cut the watermelon in cubes and remove all the seeds. Place in a blender together with freshly squeezed lime juice and stevia to taste. Pulse until smooth.
  2. Pour into the ice-cream maker (I like this one and process according to the manufacturer's instructions.
    Note: mine took just about 45 minutes. This varies based on the make of your ice-cream maker (30-60 minutes) and also depends how solid you want the sorbet to be. If you don't have an ice-cream maker, simply place the diced watermelon in the freezer for at least 3 hours and blend until smooth with lime juice and stevia.
  3. I wanted mine to be really frozen, so it took 45 minutes.
  4. When done, using a rubber spatula, put into small containers and place in the freezer. This will help you with portion control and prevent you from eating all the ice-cream in one go. If you serve the sorbet straight away, garnish with lime wedges and fresh mint. Enjoy!

Watermelon and Glycemic Index…

Although it has a high Glycemic Index (GI = 72), it has a very low Glycemic Load (GL = 4).

GL, which measures how much insulin will be released by your body for a given food measured in standard portions. This is different to GI, which doesn't take the serving size into account. As a result, some foods with high GI could have low GL. Therefore, GL is recommended as the best measure for carbs.

Other health benefits of watermelon are:

  • it's very high in water (more than 90%) which makes it filling
  • it's relatively low in net carbs and calories (7.2g net carbs and 30 kcal per 100g)
  • it's high in vitamin A
  • it contains lycopene, a carotenoid with antioxidant activity and has potential cancer-fighting abilities

Remember, only avoid watermelon or any fruit if your carbs limit is very low (20g or less of net carbs a day).

Hey great recipe as usual Smile
Could I do something similar with berries, maybe adding some water because I suppose berries don't have the same water content than watermelon.
I'm really craving some blueberry or strawberry sorbet lately but all the recipes I find use either bananas or real syrup (sugar + water) and I don't believe that fiber syrup would work ... or would it ? But anyway the quantities that I would have to use are way too sweet for my taste and too expensive


Thank you Stephanie! YEs, I would add some water if you want to use berries (especially strawberries). You may like these popsicles (you can skip the cheesecake layer or use more berries): Sugar-Free Red, White and Blue Berry Popsicles


Love how simple it is! I don't have an ice-cream maker and it worked well just blending frozen watermelon! Thanks for all the amazing posts Smile


Thanks, there will be more summer recipes soon! Smile
