low-carb watermelon slushie recipe (3 ingredients)

This easy and low-carb watermelon slushie recipe calls for only three ingredients for a tasty and refreshing summertime beverage that is free of refined sugar! Enjoy the slushie as-is or toss in a few extra add-ins for a whole new flavor spin. It's quick and simple, a light and thirst-quenching beverage that we'll be drinking all summer long (along with this sugar-free limeade!).

is watermelon keto friendly?

Watermelon is considered keto friendly since it is a low-carb fruit that also has a high water content. A ½ cup serving of watermelon only contains about 4-5 net carbs. Since there is no other added sugar or ingredients (other than water) in this watermelon slushie recipe, it's low in carbs and is keto friendly (also vegan, gluten-free, dairy free, all the things!)

the ingredient list

It's a short one, friends. You really only need two ingredients to make watermelon slushies- ice and watermelon. However, I like to add in a little bit of low-carb/keto sweetener and I'm also including a few options for different adaptations if you're looking for a fun (or boozy!) take.

• watermelon, chilled (choose seedless watermelon, cut into large cubes)
• ice cubes
• sweetener of choice (for drinks, I prefer a liquid sweetener like these monk fruit drops, stevia, or liquid allulose but you can also add in a couple of tablespoons of a granulated sweetener if that's what you have)
• optional add-ins like fresh mint, fresh basil, lime, or a low-carb alcohol of choice if you'd like to make a watermelon slush cocktail (keep reading)

And of course, a high-speed blender is a must.

let's make it

This is a basic watermelon slushie recipe that comes together in no time! While watermelon has a natural sweetness, it varies depending on the type of watermelon you buy and how ripe it is. Add sweetener to your liking (or omit it entirely).

How to make a watermelon slushie:

1. Cut the watermelon. If you have a large watermelon, you'll need to cut about half of it into large cubes (if it's medium cut up the entire watermelon). You should end up with about 4-5 cups of cubed fruit.
2. Blend. Transfer the watermelon cubes to the blender, add the sweetener (if using) and pour in 1 cup of ice. Blend for about 30 seconds to 1 minute, then check the consistency. Taste and adjust, adding more ice or sweetener as needed. (Add in any mint, basil, lime juice, etc. at this time).
3. Serve. Pour the frozen watermelon drink into chilled serving glasses and garnish with mint leaves, fresh basil, or a slice of lime (optional).

Note: For the sake of simplicity, I prefer this method, blending the chilled watermelon with ice. However, you can make an even thicker slushie if you freeze the watermelon first, then blend it with ice/water until it reaches a consistency you like.

for a low-carb watermelon slush cocktail

This watermelon slushie recipe is a great one if you're looking to make a delicious and low-carb boozy beverage! I like to add tequila with a little lime juice, but you can also go with vodka or even mix it with some of this low-carb red sangria for a sangria slush.

If adding hard alcohol, start with ¼ cup (per batch of watermelon slushie) and add more- like ½ cup- if you'd like a stronger drink. Or mix in a shot of alcohol in each individual serving.

tips for making this recipe

• If you have a little extra in the blender that you'd like to keep chilled, place the entire blender container in the freezer for a short time. I prefer this over the refrigerator since the ice will melt and water down the drink. If the slushie ends up re-freezing to the point where it's not pourable, pulse it in the blender a few times to break it all up again.
• Choose a seedless watermelon. You can make it with any kind of watermelon but some melons end up being too "seed-y" and not as enjoyable to drink.
• For a really thick slushie, freeze the cubed watermelon for 2-3 hours, then blend it with 1 cup of water and add more ice/water as needed.

This frozen watermelon drink is so easy to make and is a treat for both kids and adults alike. Somehow, watermelon in drinkable form is even more refreshing than the fruit itself, and slushies are always a fun and welcome idea in the summer.

Ingredients

• ½ large seedless watermelon, cut into cubes, or a whole medium watermelon (about 4-5 cups)
• 2 cups ice
• liquid sweetener to taste (monk fruit, stevia drops, liquid allulose), optional
• optional garnishes or add-ins: fresh basil, fresh mint, lime slices/lime juice

Instructions

1. Cut the watermelon into large cubes and discard the rind. You should have about 4-5 cups of cubed fruit.
2. Transfer the watermelon to the blender, add the sweetener (optional), and pour in 1 cup of ice. Blend for about 30 seconds to 1 minute, then check the consistency. Add the second cup of ice if needed, then blend another 30 seconds.
3. If using fresh mint, basil, lime juice, etc., at it in at this time.
4. Pour the slushie into chilled serving glasses and garnish with mint leaves, fresh basil, or a slice of lime (optional).

Notes

For a low-carb watermelon slush cocktail: Add ¼-1/2 cup of tequila or vodka to the slushie mix and blend. Alternatively, add 1 shot of alcohol to each individual serving.

For an extra thick slushie: Freeze the cubed watermelon for 2-3 hours, then blend it with 1 cup of water and add more ice and water as needed (along with the other ingredients), until it reaches a consistency you like.

If you have a little extra in the blender that you'd like to keep chilled, place the entire blender container in the freezer for a short time. If the slushie ends up re-freezing to the point where it's not pourable, pulse it in the blender a few times to break it all up again.
