How to Make Keto Lemonade

Gather a few simple ingredients, combine them in a pitcher, and cool down to an ice-cold glass of lemonade in less than 10 minutes. 

Ingredients

  • Lemon juice – Fresh lemons yield the best results in drinks like a lemon drop martini and lemonade, where lemon juice is the key ingredient. You can use bottled lemon juice for convenience, but real lemons will give you the best flavor.
  • Filtered water  – This is the main liquid component used to dilute the lemon juice and make this summer drink more hydrating.
  • Low-carb liquid sweetener – Used to sweeten the keto-friendly lemonade without the added carbohydrates, which makes it suitable for a keto diet. My favorite sweetener is a liquid monk fruit because it mixes in easily and quickly and doesn’t leave an odd aftertaste. You can save 20% by using the coupon code PRIMALEDGEHEALTH at checkout.

If you want to make this recipe ahead of time, you certainly can! Mix the lemon juice, water and sweetener together, then keep it in the fridge until you are ready to serve. Toss some ice cubes in a glass and pour in the lemonade when you’re ready.

Save any leftover lemonade in ice cube trays in the freezer. Once frozen, you can pop them out and add to a cup of sun-brewed tea or use them in a thick and creamy blueberry smoothie.

Substitutions and Variations

The best part about this low carb lemonade recipe is that with slight modifications, you can tailor it to suit your diet best and fit your lifestyle. The key to this fresh lemonade recipe is to use a liquid sweetener that complies with your dietary goals.

Check out these easy ways to modify the recipe and adjust for particular dietary needs:

  • Paleo diet – Swap out the low-carb sweetener with maple syrup or raw honey.
  • GAPS – Use raw honey instead of sugar-free sweetener.

Our version is naturally low-carb, keto, dairy-free, low-fiber, low-oxalate, and keto carnivore-friendly.

Directions

Follow these easy directions, and you can’t go wrong!

Step 1: Stir

Pour the lemon juice and water into a large pitcher, and stir together.

Step 2: Sweeten

Next, add the liquid sweetener and stir to combine, ensuring the sweetener is fully dissolved and mixed in well. Taste and adjust as desired.

Step 3: Pour

Pour over ice cubes in a tall glass and serve cold. Garnish with fresh mint leaves or lemon slices to the pitcher or in individual drinks.

In an optional last step, you can freeze your leftovers. This step is optional but a fun way to enjoy this refreshing drink. Freeze leftover lemonade in ice cube trays and add to a glass of still or sparkling water later.

Keto Lemonade Recipe FAQ

Can I make keto lemonade ahead of time?

If you want to make this recipe ahead of time, you certainly can! Mix the lemon juice, water, and sweetener, then keep it in the fridge for up to 3 days. Stir well before serving, as the sweetener may settle at the bottom of the pitcher. Toss some ice cubes in a glass and pour in the lemonade when ready.

What is the best sweetener for keto lemonade?

A liquid sugar substitute is the best keto sweetener for this easy keto lemonade recipe.  I prefer liquid monk fruit sweetener, but you can use keto simple syrup or another liquid sugar substitute, such as liquid stevia. The great thing is that you have a great selection of keto-friendly sweeteners at the grocery store – use your favorite!

Yes, you can use bottled lemon juice in a pinch as long as they have no added sugars, additives, or carbs. But fresh lemons always make the most refreshing drinks.
