Disclaimer: Consumption of alcoholic drinks negatively affects your ability to drive a car or operate machinery, and may cause health and behavioral problems if consumed in excess. On a keto diet, you might need significantly less alcohol to get severely intoxicated. Women should not drink alcoholic beverages during pregnancy. Alcohol leads to dependance. If you need help, call your local Addiction Center (In the US: (866) 399-3979, in Canada: 1-800-565-8603, in the UK: 0300-123-1110, in Australia: 1300-85-85-84, in NZ: 0800 787 797).

The first question you probably ask yourself on your keto journey is, can I drink alcohol on a keto diet? Well, the answer is yes, you can drink some alcoholic drinks but generally not cocktails that are loaded with sugar or carb-heavy juices.

For cocktails, you need keto-specific recipes like this easy keto mojito.

Whoever you want to celebrate your birthday, St Patrick’s day, or the holidays, this keto green cocktail recipe made of rum, lime, and mint, is an easy sugar-free cocktail that all your friends will love!

Is mojito keto-friendly?

No, an authentic mojito recipe contains at least 2 tablespoons of white sugar. White sugar is pure carbs, and it’s not a keto-friendly sweetener. It raises your blood sugar level and takes you out of ketosis straight away!

How to make a keto mojito at home?

A keto mojito is a sugar-free cocktail made of 6 simple ingredients. It’s a very similar recipe to a regular mojito recipe except that this recipe use:

  • This field is for validation purposes and should be left unchanged.

  • Keto-friendly sweetener – the main issue with regular cocktails is the amount of sugar added to the drink!
  • Less lime – while lime is a keto-friendly fruit in small quantities, it still contains a decent amount of carbs, about 7 grams per small lime. So to make a keto-friendly mojito, it’s better to decrease the lime slightly to keep the carbs per drink under control.

Ingredients for a low-carb mojito

  • Lime – use fresh lime. If yours is slightly hard, use my technique to squeeze out the most juice from your lime without using a lime juicer.
  • Erythritol – it’s my favorite keto sweetener in drinks, especially into a minty cocktail like this one. In fact, erythritol has a particular minty flavor and cooling effect that actually makes this keto cocktail even better than the original. Other options are using the same amount of allulose, xylitol, or few stevia drops. To learn more about sweeteners, read my review of all keto-friendly sweeteners!
  • Fresh mint
  • White rum – like many spirits, white rum is a keto-friendly spirit and doesn’t contain carbs.
  • Soda water – or club soda or sparkling water. All these drinks are carbs-free, so you can play with this ingredient to dilute the cocktail if it’s too sweet or too strong to your liking.
  • Ice – I love crushed ice, but regular ice cubes work as well.

Release lime juice

First, muddle the mint and lime wedges along with the keto sweetener of your choice. Use a mortar bowl or jug or any sturdy bowl, not a thin bowl, because you are gonna press the lime wedges strongly onto the bowl. You can use a wooden spoon or the back of a rolling pin or a pestle to do so.

I love to use a mortar and pestle to release the most juice from the lime wedges and mint leaves into the sweetener.

Assemble the cocktail

Now, pour the ingredients from the bowl into a tall glass, including the lime wedges. Then, add the ice, white rum on top, and stir the ingredients together using a straw or stick. Finally, top up the glass with soda water. The more soda water you add, the less sweet or strong the drink tastes.

Can I drink cocktails on keto?

No, you can’t drink regular cocktails from the bar without adapting the recipe. In fact, classic cocktails always contain simple syrup, sugar, or fruit juices. To make keto-friendly cocktails with a low carb count that fit your macros, you must adapt the recipe to remove sugar or juice.

If you want to order low-carb cocktails outside, ask for:

  • no juice
  • no sugar
  • add your own stevia drops or sweetener
