Keto Cocktails: 5 Low Carb Libations You’ll Love

I like to emphasize that in order to be successful in any “diet,” it needs to be easy to incorporate into your lifestyle and not feel like you are sacrificing too much. You have to enjoy your life and the process or it simply won’t stick. That’s why I love living a keto lifestyle – I don’t feel deprived, eat delicious food and can still enjoy keto cocktails and wine without too many modifications.

My new keto guide and cookbook, The Ketology Kitchen, features an entire section on cocktails and I’ve discussed previously how to enjoy your favorite cocktail without loading up on carbs. Today, I’m sharing 5 keto cocktails you can make when entertaining or for that evening cocktail – they’re satisfying, delicious and all under 4g of net carbs. Some are classics that just happen to be low carb — so they’re also safe to order when dining out — and some take a bit of preparation but are completely worth it!

First, before we get started, something I always have in my fridge is Keto Simple Syrup…it’s a great base for low carb cocktails but also works as a liquid sweetener for non-alcoholic beverages and desserts too! Keto Simple Syrup for keto cocktails is so — well simple — to make. Just take one part of your favorite granulated sweetener (I usually use Swerve or Allulose) and mix in a jar (I use a Mason Jar or these bottles I found on Amazon) with boiling water. Shake until the sweetener is dissolved and store in the fridge when cool. The simple syrup will stay fresh in the fridge for 2 – 3 weeks!

Ok, so here’s my round-up of my favorite keto cocktails.

Keto Dirty Martini Recipe

As pretty much anyone in my life will tell you, a good dirty martini is at the top of my list of go-to cocktails. I love them for happy hour or when dining out at my favorite steakhouse…and I often make them at home too. While you can use any pitted olive, I MUST HAVE blue cheese-stuffed olives with mine. It’s a requirement in my book for the perfect dirty martini.

Keto Dirty Martini with Blue Cheese-Stuffed Olives

A dirty martini is keto-approved on it’s own – without modifications, however I’m including the recipe because it is one of my favorite cocktails and fun to make at home for guests. I like to make bleu cheese-stuffed olives at home – simply take pitted green olives and your favorite bleu cheese and stuff them right before serving! However you can also easily buy jarred bleu cheese-stuffed olives at most markets.

Keto Blackberry Margarita

This is the most popular recipe on here – despite over the hundreds of food and dessert recipes, this keto margarita recipes has remained the #1 recipe since I originally made it for National Tequila Day in 2019.

A keto Cointreau normally takes weeks to make as you steep orange and lemon peels in vodka and brandy to create the liqueur. It’s certainly worth the wait and I do recommend brewing up a batch — however if you need that tangy, low carb margarita like NOW, I’ve included a simple hack below to whip up a delicious, low carb Cointreau or Triple Sec dupe in under a minute.

Keto Blackberry Margarita

Fresh blackberries are among the lowest carb fruits and add a fresh and rich flavor to this low carb margarita.

  • 2 oz Tequila I like Casamigos
  • 1.5 oz Keto Triple Sec or Cointreau check out BoozyKetones on Instagram for recipe or see recipe note below
  • 1/2 lime

If you can’t make or don’t have the patience to make keto cointreau / triple sec, here’s a great, quick alternative:
Make a batch of keto simple syrup by boiling 1 cup of water. Turn the heat off and mix in 1/2 cup of Swerve sweetener or erythritol. Shake until well combined and let cool. Add a few drops of orange extract and you have a good dupe!

Keto Cosmopolitan

Carrie Bradshaw made them famous, and I have been a Cosmo girl for years so when I went keto, this was one of the first cocktails I had to figure out how to make low carb. While the cleanest way to make this would be to use a natural or unsweetened cranberry juice, I more often use Ocean Spray’s Diet Cranberry Juice because it honestly tastes better!

Similar to the Blackberry Margarita recipe above, you’ll have to plan this one out and make keto triple sec in advance, or use the simple syrup and orange essence hack in that recipe!

Low Carb Vodka Mojitos

Mojitos are my favorite summer cocktail and this keto mojito recipe is sinfully good with a mint-infused simple syrup! I adapted one of my favorite, simple vodka mojito recipes from Giada de Laurentiis for this recipe.

Infusing my classic keto simple syrup with fresh mint makes these delicious mojitos basically guilt free (well, there's the vodka part).

  • 1 cup club soda
  • 1 cup vodka
  • 1/4 cup fresh lime juice

Mint-Infused Simple Syrup

  • 1/2 cup powdered Swerve sweetener (if you can’t find powdered, grind it in a spice grinder for a few seconds)
  • 1 cup water
  • 1 cup mint leaves, tightly packed
  • 5 – 10 drops liquid stevia optional


  • Over medium heat, mix water and powdered erythritol until dissolved. 
  • Add mint leaves and bring to a boil. 
  • Once boiling, bring heat down to a simmer and steep for 5 minutes.
  • Remove from heat and allow mixture to cool. If you want the syrup sweeter, add stevia. Test it first…I usually don’t add the stevia however I prefer this less sweet. 
  • Once simple syrup is cool, combine mint-infused syrup, vodka, lime juice and club soda in a pitcher. 
  • Stir well. 
  • Serve in ice filled glasses with some muddled mint leaves at the bottom (place fresh mint in the bottom of the glass and use a cocktail muddler–or a spoon—to crush the leaves and release it's essence). Garnish with lime and extra mint sprigs. 


I use this muddler from Amazon.

Keto Sangria

This low carb sangria is a hit at summer BBQs or if you’re looking to change up your Taco Tuesday! While you can make this at the last minute, I like to give it a few hours so the fruit flavors can steep and great more depth and richness!
