Spicy Watermelon Keto Margarita

This keto co*cktail is going to be your go-to drink of the summer! Made with a sugar free jalapeno simple syrup, lime juice, chopped watermelon and your favorite tequila, you won’t be able to get enough of this skinny co*cktail! At only 3.4 net carbs and 111 calories a serving, you can still enjoy this refreshing drink while sticking to your keto diet!

This keto drink is perfect for entertaining. The pretty light pink color makes it a great addition to any table, but especially bridal showers, brunch or any celebration you’re having! This sugar free co*cktail doesn’t use any margarita mix and it also doesn’t contain erythritol, so if you are sensitive to sugar alcohols, you won’t have a problem with this low carb drink!

I added some orange sparkling water to this skinny margarita as a substitute for triple sec, but it’s completely optional. I also think a lime sparkling water would have complimented this very well. Serve with Shrimp con Queso or Steak Fajitas for an amazing keto meal! This recipe can easily be made as a frozen margarita or on the rocks.

Whether you want your margarita sparkling, on the rocks, or frozen, it’s super easy to customize. You can also adjust the amount of spice in your simple syrup to your personal preference. This drink will cure your summer watermelon craving!

Ingredients for Watermelon Margarita

As always, here is a quick overview of the ingredients used in our keto margarita. For the complete recipe, just scroll to the bottom of the page.

• Sugar free simple syrup- made with liquid monkfruit sweetener and Jalapenos
• Tequila- Silver tequila (sometimes referred to as tequila blanco) is best for margaritas
• Lime juice- I used freshly squeezed, but the bottled version is also fine.
• Watermelon- chopped & seedless
• Optional: Orange sparkling water- you can use a different flavor or an unflavored sparkling water here. This just adds back some citrus flavor since we are omitting the triple sec
• Ice
• Garnish- lime wedges, salt or watermelon wedges (don’t add too much watermelon if you’re keto- it does have a high amount of carbs)

How to make Sugar Free Simple Syrup with Jalapenos

To make this keto simple syrup, slice up 1-2 jalapenos and add to a small pot with 1.25 cups of water. Bring to a boil, lower the heat and simmer for 10 minutes. Strain your water into a jar and add 1 tablespoon of liquid monkfruit. Store in the fridge for several weeks. Give your jar a good shake to make sure you get good, balanced flavor.

This sugar free simple syrup is so easy to make and can be customized to your particular spicy or sweetness level! If you prefer more or less sweetness, then adjust your liquid monkfruit accordingly. For additional heat, increase your jalapenos. 1 jalapeno without the seeds is going to give you a very mild flavor with just a hint of spice (perfect for those who don’t love spicy recipes). Two jalapenos without the seeds is mildly spicy, but if you prefer a hotter flavor, just add the seeds of the jalapenos!

How to make a Keto Margarita

Add your tequila, lime juice, simple syrup and watermelon to a blender. If you’re making frozen margaritas, add a glass full of ice. Blend until the watermelon is well incorporated with the rest of the ingredients. If you’re using ice, blend to a slushie consistency. Salt the rim of your glass. If you’re serving on the rocks, add ice to your glass. Add your blended ingredients, top with sparkling water and serve!

Can you make frozen margaritas?

Absolutely! Just blend everything with ice, except for the sparkling water, which you’ll add right before serving. You can use fresh or frozen watermelon.
