Keto Mango Mojito (Sugar-Free)

About This Recipe

When it comes to cocktails and mocktails, few drinks are as refreshing as a mojito. The combination of lime, mint, and sparkling bubbles creates a crisp and cooling beverage perfect for summer afternoons, barbecues, or simply winding down at the end of the day. Unfortunately, the classic mojito is loaded with sugar, making it off-limits for those following a keto lifestyle. This Keto Mango Mojito solves that problem by delivering all the flavor you love—without the carbs.

The twist here is sugar-free mango flavoring, which adds a tropical vibe without the sugar hit. You can use a keto-friendly mango syrup or make your own by blending mango extract with a sugar substitute like erythritol or allulose. The result is a fruity base that pairs perfectly with lime juice, muddled mint, and sparkling water (or club soda).

For those who enjoy cocktails, this recipe works beautifully with a splash of white rum. But it’s just as delicious as a mocktail, making it versatile for any occasion. The drink is light, refreshing, and slightly exotic—an upgrade from the usual keto-friendly beverages like flavored sparkling water or plain coffee.

Best of all, this drink comes together in just a few minutes. No complicated steps, no cooking—just muddle, pour, and stir. You can even make a larger batch in a pitcher for gatherings, so guests can enjoy a sugar-free, low-carb option that feels festive and indulgent.

Whether you’re hosting friends, relaxing on the patio, or looking for a guilt-free drink that doesn’t spike your carbs, this Keto Mango Mojito is a perfect choice. It’s sweet, zesty, fizzy, and cooling—the ultimate tropical refresher made keto-friendly.
