Ok, I’ll admit it — I’m not much of a drinker. 

I’ve been known to dabble in a few spritzers, and I even had a moment where I was obsessed with the Starbucks pink drink. But over the course in one year, the times you’ll see me with a cocktail in one hand could be counted on your free one. Those times, of course, probably revolve around certain festivities — New Years, anniversaries, and the like — not a regular Saturday afternoon. 

On a typical day, I’ll drink water and tea or (occasionally) coffee, and that’s about it. But this long, home-bound summer, I just wanted to sip on something more refreshing.

Something sweet, not bitter.

Something ice cold, not hot. 

And something that tastes refreshing on a hot summer day — which, let’s be real, ice water does not quite satisfy. 

That’s why I made batch after batch of this sugar-free lemonade for the last few months. It’s non-alcoholic, my entire family can enjoy it, and it’s much more refreshing than plain ol’ water or coffee (and sweeter too). 

Using fresh lemon juice, water, and a zero-carb sweetener, this is one sugar-free lemonade that you can feel good about. 

How to Make Sugar-Free, Homemade Lemonade 

To make this recipe, you need just three simple ingredients: water, fresh lemon juice, and granulated stevia or monk fruit. In addition, you’ll need a saucepan and a pitcher.

Start by making a homemade simple syrup, combining 3/4 cups of water and your granulated sweetener.  Cook the water and sweetener over low heat, stirring occasionally. Once the sweetener is dissolved, remove the saucepan from heat. 

Allow the simple syrup mixture to cool for several minutes before pouring into a heat-safe pitcher. Next, add the lemon juice to the pitcher, followed by two cups of cold water. Serve with ice cubes

This recipe yields four, one-cup servings. You can easily tweak the tartness or sweetness of the recipe by adding more lemon juice and sweetener. Or, if you’re serving a crowd, simply double the recipe. 

Recipe FAQs: Tips for Sugar-Free Lemonade Success 

With just three simple ingredients, this is one of the easiest summer drink recipes you’ll find on the internet. However, here a few suggestions on recipe tweaks, substitutions, and other answers to frequently asked questions: 

  • Is this recipe keto-friendly? Yes! Both stevia and monk fruit sweetener have 0 carbs and 0 grams of sugar. With lemon juice containing roughly 17 grams of carbs per cup, there are only 8.5 grams of carbs in this entire recipe — or a little over 2 grams of net carbs per serving. 
  • Is this recipe vegan? Yes! In fact, I’ll do you one better: This healthy lemonade is vegan, gluten-free, dairy-free, and low-carb friendly.
  • What kind of sweetener do you recommend? I recommend Miss Jones Better Baking MonkFruit sweetener or Lakanto Powdered Monk Fruit sweetener (affiliate links). 
  • Can another sweetener be substituted for monk fruit or stevia? If you’re looking for a low-carb or keto lemonade, I suggest you sweeten your lemonade with granulated erythritol or Swerve (which contains erythritol). All four sweeteners rank zero on the glycemic index, making them compliant with the keto diet. I just prefer monk fruit or stevia. 
  • Where can you buy monk fruit or stevia? You can buy them online, on Amazon or Thrive Market, or in most health food stores.
  • Can you bottled lemon juice instead of fresh? Absolutely. I always encourage readers to use what they have on hand, rather than traveling to the store. If you have bottled lemon juice instead of fresh, feel free to use it.
  • Can you use sparkling water instead of still? Yes, although adding sparkling water will make this lemonade recipe more of a spritzer, rather than a classic lemonade. 
  • How can you jazz this recipe up a little? You can easily make this recipe your own by tweaking the ingredients. Add some fresh strawberries to your concoction to make a homemade strawberry lemonade, or free to top with blueberries, raspberries, or other low-carb fruit. 
  • Can this recipe be made ahead of time? Absolutely. Feel free to make this drink up to six hours in advance (but don’t add any ice cubes, as it will dilute your recipe). But be sure to give it a good mix prior to serving. 
  • Will this recipe keep in the fridge? Yes, this recipe will keep for up to five days in the fridge.
