Keto Mojito

When it comes to keto cocktails, my favorite recipes to make are an espresso martini, margarita, and this keto mojito.

If I had to pick one cocktail as my favorite, it would easily be a mojito. As someone who loves sharp flavors and anything mint, a mojito ticks all the boxes. My best memories of summer include afternoon drinks with my friends, sipping on one of these drinks.

Since going keto, I was worried that mojitos and cocktails would be a thing of the past. See, while mojitos aren’t overly sweet, traditional ones do contain sugar. Luckily, you can easily make some changes and yield a classic mojito that tastes just like the original!

I’ve been meaning to share a keto mojito recipe for quite some time. It’s one of my favorite summer cocktails and pairs well with some of my favorite cuisines, like Mexican and Spanish. No sugar and no syrups are needed, but you’d never tell. The mojitos are refreshing and smooth, and have a subtle mint flavor, without being overpowering!

I had some friends over for drinks the other night and made some of these mojitos and NO ONE believed me when I told them they were low carb- They tasted like any good cocktail out there!

How do you make a keto mojito?

The Ingredients

  • Lime juice– Freshly squeezed lime juice. 
  • Granulated sweetener of choice– Monk fruit sweetener, erythritol, or allulose. 
  • Mint leaves– Fresh mint leaves to be crushed into the cocktail. 
  • Rum– White rum is preferred, but any good quality rum can be used. 
  • Soda water OR seltzer– To taste and to make the cocktail as strong or as smooth as you wish! 
  • Ice– What is a cocktail without ice? 

The Instructions

In a tall glass, combine your lime juice, sweetener, and mint leaves, gently crushing the mint with a spoon to release the flavor. Add the rum, seltzer, and ice and gently whisk together. Top with extra mint, sliced limes, and serve immediately.

Tips to make the best low carb mojito

  • These mojitos aren’t overly sweet, hence the minimal amount of sweetener. If you prefer a sweeter mojito, double or triple the sweetener.
  • Avoid using a cocktail shaker to make these, as the mint will not release any flavor. 
  • Ensure the rum you use is unflavored and has no added sugar. Many popular rums contain hidden sugars, that can kick you out of ketosis.

Flavor variations

While the classic mojito tastes incredible on its own, here are some other versions for some variety!

  • Strawberry– Replace the granulated sweetener with 1 teaspoon of keto simple syrup. Fold through 1/2 cup of sliced strawberries. 
  • Watermelon– Add 1 teaspoon watermelon extract and replace the seltzer with sugar free ginger ale.  
  • Blueberry– Add 1/4 cup of fresh or frozen blueberries. 
  • Coconut– Replace the rum with a coconut based rum with NO added sugar. Alternatively, add 1/2 teaspoon coconut extract. 
  • Blackberry– Add 1/4 cup of fresh or frozen blackberries.

What to serve mojitos with? 

Mojitos have quite a sharp and robust flavor and tend to pair very well with seafood-based dishes. Salmon, tuna, ceviche, or even fish tacos are all fantastic options. They also go great with Mexican and Spanish dishes.
