If you have ever been to an amusement park, county fair, or state fair, you may already know how popular fresh-squeezed lemonade is.

Furthermore, if you have enjoyed a glass of it, you probably understand why there are long lines of people waiting at the fresh-squeezed lemonade stand.

The long wait is usually worth it because lemonade from fresh lemon juice tastes better than anything of its kind!

It’s perfectly refreshing; plus, it will help to keep you hydrated in the hot sun.

Ever wondered if you can have lemonade on the keto diet? The answer is, yes, you can! This sugar-free lemonade recipe is perfect and will keep you within your macros.

Ingredients Needed For Sugar-Free Lemonade

There are four simple ingredients in this refreshing drink, and they are all really easy to find.

Here’s what you need:


You’ll need about 5 lemons to make 8 cups of lemonade. Jarred lemon juice won’t work as well as fresh lemons. So, use the fruit – it works so much better!


The type of water isn’t as important since you are using lemon juice and sweetener. If your tap water has an aftertaste, consider using filtered or bottled water for this lemonade recipe.

Monk Fruit Drops

Any type of granular or liquid sugar-free sweetener will taste delicious in this drink. I used monk fruit drops because they don’t have a strong aftertaste, and they dissolve really well in the water.

Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.

Quick Tips:

Here are a few ways you can change this lemonade recipe to make it completely different.

  • Try kiwi. Add slices of kiwi fruit. Not only will the lemonade taste amazing, but it will also be beautiful!
  • Spike it. A splash of vodka will turn ordinary sugar-free lemonade into an adults-only keto drink.

What kind of sweetener is best for sugar-free lemonade?

There are several options when it comes to sweetening your sugar-free fresh-squeezed lemonade.

The recipe below calls for lemon monk fruit drops. Other low-carb and keto-friendly sweetener options that dissolve well in lemonade include:

My sweetener of choice is lemon monk fruit drops because they offer an extra boost of lemon flavor. Lemon stevia drops work as well.

How long will the lemonade stay fresh?

As long as it is kept in the refrigerator, lemon, orange, or any other fresh squeezed juice will usually stay fresh for 7-10 days. At that point, it usually starts to lose its flavor and may even take on a cloudy appearance.

The good news is, freshly squeezed lemon juice can be frozen, and if you really want to, you can even freeze the lemonade. Just be aware that it may lose some of its flavor during the thawing process.

An easy and convenient way to freeze lemon juice is to use ice cube trays. When the juice is frozen, just release the cubes from the tray and transfer them to a large freezer zip-top bag.

Then, when you want to make some sugar-free lemonade, just add water and sweetener into a pitcher, add a few of the frozen juice cubes and stir to combine.

This sugar-free lemonade tastes just like the drink you loved as a kid! In fact, your family is probably going to ask you for the recipe. So make a pitcher, and keep this recipe safe – you’ll be using it over and over again.
