Summer Keto Raspberry Lemonade

Pin recipeFollow us 50.3k

Summer is the most challenging time of the year for cutting carbs, especially with all the sweet seasonal fruits. The best way to avoid going over your carb limit by eating fruits is to stick with berries.

One of the many ways you can enjoy berries is in homemade lemonade, or in this case, lemonade / limeade :-) Apart from being low-carb, lemons also have a positive effect on blood sugar control. I personally don't use any sweeteners and don't mind the sour taste but that may be too much for most people so I included some Stevia and Erythritol (or you can simply use just one of them).

My recipe only uses the raspberries to infuse the lemonade and add flavour boost and colour. If you prefer a more raspberry-rich taste, you will love this Raspberry Limeade from Carolyn of All Day I Dream About Food. I made it for a BBQ last month and it was a hit!

Ingredients (makes 8 servings)

  • ¾ cup fresh lemon juice (3-4 lemons)
  • ¾ cup fresh lime juice (4-5 limes)
  • 1 cup raspberries (123 g / 4.3 oz) - you can try other berries too, blackberries work great!
  • water, still or sparkling (2 litres + more still water for raspberry ice cubes)
  • ¼ cup Erythritol or Swerve, powdered, or other healthy low-carb sweetener from this list (40 g / 1.4 oz)
  • 30 or more drops Stevia extract
  • mint for garnish

The main reason I use two sweeteners in most of my recipes is that a combination of more sweeteners mask the aftertaste / bitterness of some of them. Depending on you palate, you may need to use more or less sweetener.


  1. Make the berry ice cubes by placing the berries in an ice-cube tray and top with still water. Place in the freezer for at least 2 hours or until frozen.
  2. When the ice is ready, start juicing the lemons and limes (you can use just lemons or limes if you don't have both).
  3. Pour the juice into a large jug and add sparkling or still water. You can use more water if the taste is too strong for you.
  4. Add the stevia (I used Lemon drops from SweetLeaf) and powdered Erythritol. Make sure you use powdered Erythritol or Swerve - otherwise the crystals won't dissolve. Mix until well combined and no sweetener is on the bottom of the jug.
  5. Pour the lemonade in serving glasses and add the raspberry ice cubes. Garnish with fresh mint and enjoy! Store up to 5 days in the fridge and add the raspberry ice cubes just before serving.

The glycerites are even better than the powdered stevias. Just the unflavored ones work great--I like NOW brand the best. I use essential oils for flavoring also. Just a literal drop or two is enough. Lemon, orange, peppermint...


I agree, essential oils are great for flavour boost!


Can you use the powdered Stevia?? Or will it not dissolve?


I think it should. I don't use powdered stevia but the one I've tried dissolves well Smile


We are having lots of hot weather lately.  This is perfect, I'm making this ASAP! YUM!


Thank you Maggie, hope you like it! Smile


I've never thought of making "berry cubes" before, looks like a cool idea for a barbecue! I may skip the sweetener too because I don't seem to crave sugar any more Smile


Thanks Ava!!
