This Low Carb Mojito is a refreshingly sweet mix of fresh mint and white rum (or vodka!) that takes this low carb cocktail to the next level. Serve it to your friends and family any time of year!

The Lowest Carb Alcoholic Drink
I am always looking for fun and festive ways to enjoy cocktails throughout the year while still staying true to my low-carb diet.
A regular Mojito cocktail comes in at 13g net carbs, since most of the carbs come from sweetening the drink with cane sugar. And don't even think about purchasing a low carb mojito mix, which is packed with tons of added ingredients that aren't good for you.
To keep the sweetness, but decrease the amount of sugar and carbs, I discovered you can replace the sugar with Diet 7up for a low carb no sugar mojito. It is just as delicious (if not more!) and keeps the carbohydrates count in check.
- Carbs in Unflavored Spirits: All unflavored spirits (rum, vodka, tequila, gin) have zero carbohydrate content. When you get into the world of flavored spirits, such as coconut rum which has 8 grams of net carbs in a 1.5oz serving, the sugar and carb content increases. Stick with unflavored for the lowest possible carb cocktail.
- Diet 7up has zero net carbs because it is sweetened with Splenda. Feel free to also use Sprite Zero Sugar, which has zero net carbs, too.
- Lime Juice has 1 gram of net carbs which makes the total net carbs = 1 gram per drink as long as you stick to all unflavored mixers.
Mojito Ingredients
A classic Mojito cocktail is a refreshingly sweet cocktail that makes you feel as if you are on a tropical island, basking in the sunshine.
Here's what you need to make a new and improved Low-Carb Mojito Cocktail recipe:
- Mint Leaves: Fresh, vibrant mint leaves make all the difference. Purchase them from the market the day you are going to make the cocktail for the best flavor. They even sell small mint plants at Trader Joe's that you can keep in your windowsill and water from time to time. That way, fresh mint is always at the ready!
- White Rum or Vodka: The alcohol is really your preference. White rum is more traditional (I like Bacardi), offering a sweeter, tropical flavor, but Vodka will work just as well. To keep the carb count in check, I would omit from making a low carb coconut mojito by using a flavored coconut rum and stick to unflavored spirits.
- Lime Juice: Use freshly squeezed lime juice. It adds that extra special brightness you just can't get from the store-bought bottled version.
- Club Soda: I prefer the Citrus Fresca brand, but your favorite club soda will do. Make sure to use an unflavored, sugar-free variety.
- Diet 7Up: The diet 7Up helps keep the low-carb in this low-carb cocktail. 7Up's flavor is so mild, you won't notice the difference in the diet version.
- Garnish: Lime slices and fresh mint leaves add that extra special touch.
How To Make Low Carb Mojito
Here are three easy steps to making a refreshingly vibrant Low Carb Mojito Cocktail:
- Add the mint leaves to your favorite cocktail glass. Muddle for a few moments to release all those natural oils. (pic 1 & 2)
- Add ice, about halfway, or as much to your preference, then add the white rum or vodka, lime juice, club soda and diet 7up and stir for a few seconds. (pic 3-6)
- Garnish with fresh lime slices, mint leaves and enjoy!
Should I Serve The Low Carb Mojito In a Highball Glass?
Although a highball glass (the tall glass in the photo below) is classic, it is not necessary for this low-carb mojito recipe.
The point of a highball glass is to serve "tall" cocktails that contain a large proportion of a non-alcoholic mixer as compared to the alcohol. Often it is used interchangeably with the Collins glass.
But in my opinion, your favorite cocktail glass will do the trick!
The Best Low Carb Mojito Recipe That Is Keto-Friendly
Pure spirits like unsweetened rum and vodka have zero carbs. And when you pair the alcohol with zero or low-carb mixers, the cocktail is easily keto-friendly.
The carb breakdown for the low-carb mojito is as follows:
- White Rum or Vodka: Zero carbs, as mentioned above.
- Lime Juice: Two teaspoons contains approximately 1g carbs.
- Club Soda: Zero carbs, as it is simply carbonated water.
- Diet 7up: Zero carbs since Diet 7up is sweetened with Splenda.
That brings the total of our low-carb mojito to 1g carbs - 12g of carbs less than the amount in a classic mojito cocktail!
Low Carb Mojito Pitcher - Mojito Cocktail For A Crowd
The low carb mojito is a beautiful and refreshing drink to serve to your friends and family, too! To make a Low Carb Mojito in a pitcher, simply:
- Muddle the number of mint leaves to the desired quantity in a large pitcher.
- Add the appropriate amount of white rum (or vodka) and lime juice and refrigerate.
- When your guests arrive, add the club soda and diet 7up and stir a few times.
- Fill your cocktail glasses with ice, about halfway, and pour the cocktail over. Garnish with fresh lime slices and mint leaves.
How to Make a Virgin Mojito
Simply skip the rum, or vodka, and enjoy a refreshing and yum Virgin Mojito.
Recipe Tips For Low Carb Mojito
- Citrus Fresca Club Soda: This is my preferred brand of club soda, however you can use any of your favorite. Just make sure it is unflavored and sugar-free.
- White Rum or Vodka: For best results, use your favorite unflavored white rum (such as Bacardi) or vodka.
- Ice: If you don't like ice in your drinks, use a cocktail shaker. Fill it with ice (to chill), add white rum or vodka and lime juice, shake a few times. This chills the drink. Pour the drink in a highball or cocktail glass with muddled mint leaves, then top off with club soda and diet 7up. Stir a few times to mix everything together.
- To make a Virgin Mojito, simply skip the rum, or vodka, and enjoy a refreshing and yum Virgin Mojito.
- When muddling mint leaves, do it gently. Over muddling can make the mint leaves a bit bitter.
