My keto margarita recipe is a low-carb take on the classic Mexican-inspired cocktail. Simple yet fancy, with 5 delicious flavor combinations!

As someone who enjoys a good cocktail now and then, I can attest to how challenging it is to find keto versions of my favorite cocktail: margaritas. Today, though, I have you covered with my homemade recipe.
While traditional margaritas are not keto-friendly (up to 30 grams of carbs per serving!), my version has zero carbs (seriously), but tastes like the real thing.

Why I love this recipe
- It just tastes good! It’s chilled, smooth, and goes down dangerously easy. The subtle sweetness from the lime and orange pairs perfectly without being overpowering.
- Easy to customize. Fruity, sharp, or with sweeter notes, you can customize this cocktail any way you like.
- Uses real keto simple syrup. Thanks to my keto simple syrup, this truly tastes like the original.
If you want another keto friendly drink, try my keto mojito, keto drink mix, and keto lemonade next.
★★★★★ REVIEW
“This is so good. Margaritas are my favorite and my go-to cocktail. I’ve done keto in the past, but recently just started focusing on a low-carb lifestyle and really missed my margaritas. This has become my go-to low-carb recipe” – Kaitlin
Key Ingredients
- Tequila. Use good quality and subtly flavored tequila, like Patron or Don Julio.
- Simple syrup. Adds a little bit of sweetness adding no extra carbs or sugar. I used a keto simple syrup.
- Orange extract. Gives some lovely orange flavor, with no oranges needed.
- Soda water, seltzer, or water. To thin out the margarita, if you prefer some fizz, opt for soda water or seltzer.
- Limes. Fresh limes juiced, with several slices for decoration.
- Ice. A must for any good cocktail.
How to make a keto margarita
Step 1- Add ingredients. Add all of the ingredients to a cocktail shaker and shake vigorously for 1-2 minutes.
Step 2- Serve. Carefully strain the margarita into two glasses and garnish with a lime wedge, then serve and enjoy!

Low Carb Margarita Variations
- Tone down the sweetness. If you prefer a less sweet margarita, omit the simple syrup and use seltzer or soda water.
- Amp up the flavor by using lime or lemon-flavored seltzer.
- For aesthetic purposes, lightly brush the edges of the glass with water and sprinkle with coarse sea salt.
- For a keto margarita mix, you can prepare all the ingredients, minus the water/seltzer up to two weeks in advance. When ready to enjoy, add the mixture, along with the seltzer, into a cocktail shaker, mix, and serve!

This is so good. Margaritas are my favorite and my go-to cocktail. I’ve done keto in the past, but recently just started focusing on a low carb lifestyle and really missed my margaritas. This has become my go-to low carb recipe. If you’re doing dirty keto or just a low carb lifestyle, Sprite Zero works well instead of seltzer and keto sweetener. Prosecco also makes a good bubbly substitute for a boozier version.
