Keto Simple Syrup

This Keto Simple Syrup involves only 2 ingredients, and is the perfect 0-carb, 0-calorie alternative to sugary mixed drinks! Liquid monk fruit replaces sugar for a healthy and super diet-friendly substitute for your classic simple syrup.

Turn your favorite cocktails keto by replacing your simple syrup with this sugar-free version! From margaritas to mint juleps, lemon drops to gin fizzes, this syrup is exactly what you need for an amazing keto happy hour.

This sugar free simple syrup works wonderfully in a Sugar Free Lemonade, a Keto Margarita, a Keto Lemon Drop, or any beverage that requires a simple syrup base! It will keep for a month or longer in the fridge, so mix up a quick batch and have it prepared whenever you’re in the mood for a drink.

How to Make Sugar Free Simple Syrup

For this recipe, you only need two ingredients: Water and liquid monk fruit sweetener. 

Normally, you would need to boil your water, then stir in your sugar to help it dissolve. With liquid monk fruit, you can skip this time-consuming step! Take any cup of water (I use the filtered water from the fridge), add one tablespoon of liquid monk fruit sweetener, and stir. This can be used immediately or stored in the fridge or countertop.

To make a “rich simple syrup,” use 2 tablespoons for each 1 cup of water. This is equal to using 2 cups of sugar per 1 cup of water.

Can I use erythritol for keto simple syrup?

In my experience, no, I would not recommend using any product with erythritol in a simple syrup. I love using Lakota’s monk fruit blends with erythritol in my cookies and cheesecake, but it does not work for a simple syrup.

Erythritol simply will not completely dissolve–It will appear to be dissolved when the syrup is hot, but it begins to crystallize as the syrup cools down. This will leave you with a very unpleasant drink… Gritty with some super sweet sips and some sips without any sweetener at all.

I have read that adding a pinch of xanthan gum to your simple syrup (when made with a erythritol blend) will prevent crystallization. I can’t promote this because I haven’t tried it, though… The liquid monk fruit works SO well and requires no heating, so I have stuck with this inexpensive, easy method.

How to use Keto Simple Syrup

Keto simple syrup is AMAZING in cocktails and can be used as a 1:1 substitution! In any recipe that calls for simple syrup, you can sub in this sugar-free version using liquid monk fruit sweetener.

Just like a regular simple syrup, you can use this method for infused or flavored syrups as well! Here are a few of my favorite versions:

Blackberry Simple Syrup – Sugar Free & Keto

To add delicious blackberry flavor to any cocktail, boil 2 cups of blackberries in 1 cup of water for roughly 20 minutes. Occasionally mash the berries as they are boiling so they become completely macerated. Remove from the heat and allow to cool for 20 minutes. Strain, add 1 tablespoon of liquid monk fruit, and pour into an airtight jar or bottle.

Use as a 1:1 replacement for simple syrup. I used this to create a delicious Blackberry Bourbon Smash — Only 2.5 net carbs and 157 calories for a generous summer keto cocktail!

Rosemary Simple Syrup – Sugar Free & Keto

So many herbs pair perfectly with liquors for refreshing, fun drinks! For this Rosemary Gin Fizz, I started by making a rosemary simple syrup. Boil 1/4 cup of rosemary leaves (stripped from the stem, roughly chopped if you want a stronger flavor) in 1 cup of water for 10-15 minutes. Allow the syrup to cool for about 10 minutes, then strain, add 1 tablespoon of liquid monk fruit, and pour into an airtight jar.

Jalapeno Simple Syrup – Sugar Free & Keto

For a spicy kick, you can simmer a diced jalapeno (or 2!) in water for about 10-15 minutes. The amount of jalapeno depends entirely on your spice level preference… If you only like a little kick, slice 1 jalapeno (toss the seeds) and boil in 1 1/4 cups of water. If you like it hotter, you can add the seeds and/or use 2 jalapenos for a spicier syrup!

Allow syrup to cool for about 10 minutes, then add your liquid monk fruit, strain, and store in an airtight container. This made the PERFECT Spicy Watermelon Keto Margaritas! 

 

Basil Simple Syrup – Sugar Free & Keto

For a relaxed summer get-together drink, I developed this Basil Whiskey Sour using an infused sugar free simple syrup. Bring 1 cup of water and 1/2 cup of torn basil leaves to a boil and allow to simmer on low for 15-20 minutes. Let it cool for 10-20 minutes, strain, add your monk fruit, and then transfer to an airtight container in the fridge.

Kiwi Simple Syrup – Sugar Free & Keto

Kiwi fruit is not considered keto. Very small amounts can be worked into your macros, but the high sugar content means that it’s usually (sadly) off-limits. However, you can use kiwi to make this Kiwi Cucumber Gin Cocktail for a special treat (around 6 net carbs per drink)!

Use 2 cups of chopped, peeled kiwi with 1 cup of water and 1 tablespoon of liquid monk fruit. Boil the fruit in water for 15-20 minutes, mashing occasionally. Allow it to cool for about 20 minutes, then strain, add your monk fruit, and pour into an airtight container.
