A delicious cocktail for any time of year. This sweet and sour lemonade is sugar-free; just add a couple splashes of your favorite vodka and you've got yourself a refreshingly boozy drink.
Just because you’re watching your carbs doesn’t mean you can’t enjoy a blended cocktail every now and then.
This vodka lemonade has all the elements of a perfect beach cocktail. It’s slightly sweet, mildly tart and blended to form a fun umbrella drink I love making poolside during the warm weather season.
This recipe is naturally gluten-free and sugar-free and will help get the party started when you have friends and family over! I like to serve it alongside other refreshing cocktails, like a low-carb margarita, sugar-free strawberry daiquiri or a mojito.
You can easily turn this into a strawberry vodka lemonade by using sugar-free strawberry lemonade. Or if you’re fighting a hangover the next day, try a charcoal lemonade drink with any leftover lemonade you have.

Can I use a different sweetener instead of monkfruit?
Absolutely! If monkfruit isn't your preference, you can substitute it with another sugar alternative like erythritol, stevia, or allulose. Just adjust to taste as sweetness levels vary.
How can I make this drink non-alcoholic?
To enjoy a refreshing non-alcoholic version, simply omit the vodka and add more sparkling water or soda water for some fizz. You can also enhance the flavor with additional fresh herbs or fruits like mint or berries.
What’s the best way to store leftover keto vodka lemonade?
If you have any leftovers, store the vodka lemonade in an airtight container in the fridge for up to 2 days. The carbonation from any added soda will diminish over time, so it's best enjoyed fresh!
Is this recipe suitable for meal prep?
Yes! You can prepare the lemonade base ahead of time and store it in the fridge. Just add vodka right before serving to keep it fresh!
How can I make this drink less tart?
If you find the drink too tart, you can add a little more sweetener or mix in some flavored sparkling water. Adjust according to your taste preference!
Added a few fresh mint leaves before blending and it came out tasting like a mojito-lemonade crossover. Not sure I can go back to the original version at this point.
8 months keto, no cocktails, nothing felt worth the carb math. Made this with fresh-squeezed lemon last weekend and completely killed that logic. 4.6 net carbs for something that actually tastes like a real drink.
Made this five or six times now. Been dialing back the monkfruit so the lemon really comes through, and it hit that balance perfectly last night. Cold February outside, but lemonade still works somehow.
Lemonade in February is valid. I actually go lighter on the monkfruit too, somewhere around 1/3 cup - that's when the lemon really cuts through instead of just sweetening everything.
Made this on a cold night last week and it was perfect, but the monkfruit kept settling grainy at the bottom of my glass. Do I need to blend it longer, or should I dissolve it in warm water before adding everything?
Warm water first. Dissolve it in a few tablespoons of warm water before you add everything else and it won't settle.
I was honestly nervous about making this (never really made cocktails from scratch), but blending the lemon juice and monkfruit together first actually worked great. Only 4.6g net carbs per serving is pretty wild for a lemonade drink. Does the monkfruit sweetener dissolve fully when you blend it or does it leave any gritty texture?
Blending takes care of it. Monkfruit dissolves pretty fast in liquid so you won't get that gritty texture you'd get just stirring it in. 4.6g for a cocktail is kind of hard to believe, right?
