While you do need to be aware of the sugar and calories you’re consuming with any liquor, there are certain liquors that will still fit into a keto diet. One of those is tequila, which is used to make a margarita.

Is Tequila Keto Friendly?

Clear liquors, like tequila and vodka, contain no carbs and no added sugar. Tequila has 69 calories per ounce and no carbs, so it is fine to drink on a keto diet, in moderation, of course.

A keto margarita is made with 1.5 oz of tequila, so you’re looking at about 110 calories from the liquor.

Of course there are other ingredients in a margarita that will add to that total. One of the biggies is Cointreau, which is a slightly sweet orange-flavored liquor. In 1 oz of Cointreau, there are 95 calories and 7.4 grams of carbs.

So Cointreau isn’t going to work for this cocktail. While it does add a little bit of orange essence to the cocktail, it’s not enough to actually need replacing. However, you can replace the orange flavor if you want to with just a spritz of orange peel. Cut a slice of orange peel and twist it over the glass to mist the cocktail with orange essence.

What Sweetener to Use

What does need replacing is the sweetener. Otherwise the lime juice would be overpoweringly sour. My secret weapon for this and any other cocktail I make that needs sweetening, to give it a bit of sweetness and reign in the sourness of the lime, is sugar-free simple syrup.

You can make your own simple syrup by combining equal parts sugar substitute, like allulose or erythritol, and water in a sauce pan and heat it until the sugar is fully dissolved. Then allow it to cool. It keeps in the refrigerator for up to a week, so you can use for other things.

You can also purchase it to make it super simple. I use sugar-free simple syrup from Wholesome Yum. It’s a zero calorie, zero carb sweetener made with monk fruit and allulose. It’s perfect for cocktails. Purchase it using our affiliate link above and get 10% off with coupon code: DLC10.

How to Make a Keto Margarita

There are three easy steps to making this cocktail. You’re going to need a cocktail shaker, a margarita glass, rim salt, and ice.

Step One: Salt the Rim

The first step is to salt the rim of the glass. Use a piece of lime to wet the rim of the glass all the way around. Then pour the rim salt onto a plate and roll the rim in the salt until it’s coated to your preference.

Add ice to the glass. I like to add a lot of ice so it dilutes the drink a little and lasts longer.

Step Two: Mix the Cocktail

Next, juice the lime. It’s important to use fresh lime juice for this cocktail. I use a citrus juicer to easily extract the juice from the lime just before putting it into the shaker.

Fill the cocktail shaker with a handful of ice. Pour the lime juice, tequila, and simple syrup into the shaker. Shake vigorously until the cocktail is sufficiently chilled.

Step Three: Pour

Pour the cocktail over the ice in the glass. If there’s room in the glass, you can pour the remaining ice from the shaker in as well. Garnish with a lime wedge.

Optional Steps

On it’s own, this is a small drink. It’s not going to fill a large margarita glass. For that reason, you may want to add sugar-free soda water to the cocktail to make it last longer. If you want to flavor your margarita, you can add a flavored soda water – strawberry soda for a strawberry margarita, for instance.

Adding soda water will definitely water down the drink, so skip this step if you’d rather have a strong classic margarita.

You can also blend the margarita, if you want. Just add all of the ingredients to a blender until smooth.

Additional Flavor Combinations

I classic margarita is hard to beat. If you are in the mood for something different you might try one of these flavor combinations to kick up your margarita.

  • Jalapeno slices
  • Fresh herbs like mint, cilantro, basil or rosemary.
  • Cucumber
  • Mezcal – exchange the tequila for a smoky mezcal instead

What to Eat with Keto Margaritas

It’s fun to have some snacks to enjoy with your margarita. Here are a couple of our favorites. These keto mini pepper nachos are a great way to enjoy the flavors of nachos without the tortilla chip. These buffalo chicken wings and BBQ grilled cauliflower skewers are always a crowd favorite. If you are looking for something a bit lighter you might try these baked eggplant caprese snacks.

Keto Margarita FAQs

Can I make this a blended margarita?

Sure! Just add all of the ingredients to a blender until smooth.

Are keto margaritas sugar-free?

We use a sugar substitute to keep this as sugar-free as possible. Limes do have some natural sugar so this margarita is refined sugar-free.

What is a skinny margarita?

Skinny cocktails are low-calorie versions of an original. The main difference is the amount of sugar added.

    I like to remind Margherita lover’s that when salting the rim of your glasses is to make sure that you don’t let any salt fall into the glasses as your last sip of your cocktails will be like drinking salty ocean water!
    Cheers! 🍸
    Chef Steve!
