How to Make It (Step-by-Step Instructions)
Step 1: Blend the watermelon
Place the fresh watermelon cubes into a blender and blend until smooth. You’ll want about 1/2 cup of watermelon juice per margarita, so feel free to blend extra for a few rounds.
Step 2: Prepare your glass
If you’re rimming your glass with salt or Tajín, run a lime wedge around the edge of the glass to moisten it, then dip it into a plate of salt or Tajín for a fun, zesty rim.
Step 3: Mix the margarita
In a cocktail shaker, combine the watermelon juice, tequila, lime juice, triple sec, and agave syrup (to taste). Add a handful of ice to the shaker and shake vigorously for about 10–15 seconds until well chilled.
Step 4: Serve and garnish
Fill your prepared glass with ice and pour the margarita mixture over it. Garnish with a lime wedge or a slice of watermelon on the rim for a little extra flair.
Step 5: Enjoy!
Sip and enjoy the refreshing, light, and perfectly balanced flavors of your Skinny Watermelon Margarita. Cheers to summer in a glass!
Helpful Tips
- Make it ahead: Blend the watermelon and mix the margarita base ahead of time. Keep the mixture in the fridge, and when you’re ready to serve, just shake it up with ice.
- Adjust sweetness: If you prefer a sweeter drink, add more agave syrup or honey. You can also make a simple syrup if you want more control over the sweetness.
- Use frozen watermelon: For an even slushier texture, freeze watermelon cubes and use them in place of ice. It makes the drink even more refreshing.
- Add a little extra: Want a more tropical twist? Try adding a splash of coconut water or pineapple juice for a fun variation.
- Non-alcoholic version: Skip the tequila and triple sec and add a little extra lime and watermelon juice for a mocktail version.
Frequently Asked Questions (FAQs)
Can I use store-bought watermelon juice?
Sure, but fresh watermelon will give you the best flavor. If you’re in a pinch, just make sure the juice is 100% watermelon with no added sugar.
What if I don’t have agave syrup?
No problem! You can use honey, simple syrup, or even a bit of stevia to sweeten it up.
Can I make this in a big batch?
Absolutely! Just scale up the ingredients for a pitcher and refrigerate it. When you’re ready to serve, pour it over ice and garnish each glass individually.
What if I don’t like tequila?
You can substitute vodka or rum if you prefer those spirits, but tequila definitely gives it that signature margarita flavor.
Can I make this frozen?
Yes! Blend the watermelon, tequila, lime juice, triple sec, and sweetener with ice in a blender for a frosty, slushy version.
