Is an Espresso Martini Keto-Friendly?

Turns out, yes, you can enjoy an Espresso Martini while still being keto and low-carb. This delicious drink is low in carbs and calories but doesn’t skimp out on flavor.

Traditionally, this cocktail also calls for a coffee liqueur, but since that is typically loaded with sugar, we will leave it out.

A good Espresso Martini starts with good espresso. This keto-friendly espresso martini doesn’t miss the coffee liqueur when a espresso shot is enough to give a bold flavor. You won’t miss the extra sugar and artificial flavors from the liqueur. Who could?

But we’ll still need a sweetener, right? Yes. But to stay consistent with keto and low carb, we have to use a sugar-free sweetener. The sweetener of choice for a martini is simple syrup, and thankfully there are plenty on the market that are keto-compliant.

There are other options for sweetening without carbs if you don’t have sugar-free simple syrup. See substitutions below. 

Whatever sugar-free sweetener you decide to go with, it’s clear that you need to make this drink soon! 

It’s a simple recipe that is great for small and large parties alike. In fact, with such minimal prep, it can even be done when guests arrive without missing any conversation. Impress them with your admirable bartending skills and show off that beautiful frothy foam. 

Don’t worry – I won’t share with your guests how super easy this recipe actually is!

How to Make a Keto Espresso Martini

Gather 3 ingredients, and you’re halfway to making a keto-friendly espresso martini in just 5 minutes! It’s that simple.

Just shake everything together, strain, and pour into a fancy glass for a fun drink. 

Best keto martini

Ingredients

  • Espresso shot – you’ll need 1 shot (1 ounce or 30mL) of espresso. For best results, use freshly brewed and steaming hot espresso. This is the key to making it frothy!
  • Vodka 
  • Simple syrup – to make sure this drink truly stays keto, be sure to use sugar-free simple syrup. 

I suggest Lakanto’s keto-friendly simple syrup. You can save 15% by using the code PRIMALEDGEHEALTH at checkout.

Substitutions and Variations

This Keto Espresso Martini is great as is with those simple ingredients, but you can make it your own with these variations:

  • Vanilla Espresso – add ½  teaspoon of vanilla extract
  • Mocha Martini – flavor your martini with ½ teaspoon of cacao powder or cocoa powder
  • Virgin Espresso Martini – to make an alcohol-free mocktail, replace the same amount of vodka with water, more espresso, or heavy cream
  • No sugar-free simple syrup? No worries – just sweeten with powdered sweetener instead. But dissolve the sweetener in the hot espresso first to avoid grittiness. You can also use 10 drops of liquid monk fruit sweetener or stevia instead. My homemade stevia extract is great in this recipe.
  • No espresso? Make this cocktail with extra strong cold brew coffee instead.

Step-By-Step Directions

Follow these simple directions, and you can’t go wrong! This easy Keto Espresso Martini has very minimal prep with only 5 minutes of active time and 2 steps! It’s that easy. 

Step one: Shake

Add freshly brewed hot espresso, vodka, and sweetener to a cocktail shaker with 1 cup of ice. Shake vigorously for about 30 seconds until all chilled and frothy. Remember, the hotter the espresso, the more frothy your drink will be. 

If you don’t have a cocktail shaker, you can use a regular mason jar, as shown in this Gnom Gnom post. 

Step two: Strain and enjoy!

Strain the shaken martini through a fine mesh sieve directly into a chilled martini glass. Garnish with a few coffee beans and serve immediately.

Espresso Martini FAQ

How to make an espresso martini without espresso?

You can make a delicious espresso martini without espresso. Although the flavor won’t be as bold, you can use cold brew coffee or regular coffee. I would recommend using the best quality coffee, though, for the best flavor. Another option is to use a coffee liqueur, but that often comes with ingredients that are not keto compliant so use that with caution.

To get a super frothy espresso martini, you need to be mindful of these two things: one, make sure your espresso is freshly brewed and still steaming hot. And two, shake vigorously to form more bubbles in the foam.

  1. Hello! How do you get it chilled if you use steaming hot espresso? Are you adding it to a half-filled cocktail shaker filled with ice? It’s not in the directions but as that’s how you usually make a martini, I used ice in the cocktail shaker last night and the martini was VERY diluted with water because espresso immediately melted the half-full cocktail shaker of ice. Thank you!

    • Hi Tara, Let’s see, the hot espresso is needed to get the frothy head. There should be 1 cup of ice in the shaker, and then serve in a chilled glass. I’ve updated the directions to be more clear about this. Thank you for sharing your experience and helping me make the recipe better!
