Watermelon Mocktail Recipe

I don’t drink much alcohol, but that doesn’t mean I don’t enjoy a fun and refreshing drink! Especially on a hot summer day, I really love to have a tasty non-alcoholic drink in hand.

My peaches & cream mocktail and collagen kombucha mocktail are two of my most popular recipes ever. So if you like those, you’ll definitely like this watermelon mocktail too! It’s delightfully refreshing and really simple to make.

Watermelon is one of the most hydrating fruits ever, which definitely makes this a summer worthy drink. The best thing is that whole family can enjoy it because it’s kid-friendly.

Beat that summer heat with this incredible summer drink. It’s the best way to enjoy that relaxation time next to the poolside. So follow these few simple steps and then kick back and enjoy this delicious mocktail while you soak up that sunshine.

Why You’ll Love this Recipe

This recipe captures that ripe watermelon flavor so well. It’s the perfect use for that leftover, juicy watermelon:

  • A watermelon mocktail is incredibly hydrating! Watermelons are more than 92% water and are full of vitamins and nutrients that are great for your body.
  • You can make the watermelon juice mixture ahead of time and store for later. Then easily throw together some drinks for a party!
  • This is a great way to encourage picky eaters to get their daily dose of fresh fruits. If they don’t want to eat it, then maybe they’ll drink it!

Ingredients

You only need a few summer staples to make this wonderful drink come to life in your home! Here’s what you need:

  • fresh watermelon: Summertime has a great selection of seedless watermelons! There are tips to choose the best watermelon here.
  • lime juice: For the best flavor, use freshly squeezed lime juice. The bottled stuff just isn’t as fresh.
  • Seltzer: I like to use unflavored, but lime or watermelon LaCroix is great for a double whammy of watermelon goodness!
  • fresh mint: The perfect way to make the most refreshing drink — just add fresh mint!

Substitutions and Variations

Want a boozy twist on this drink? Add 1oz of vodka per glass and stir well to combine.

Fresh basil would be a nice, extra herby addition to this mocktail. You can also add in some cucumber for an extra refreshing flavor. Or make this mocktail extra fruity with fresh orange juice or strawberries.

You can use unflavored sparkling water or flavored. Lime and watermelon sparkling water is also delicious! Club soda would also work in this recipe!

If you want your drink to be a little sweeter, then add in some honey or simple syrup.

How to Make a Watermelon Mocktail

This watermelon lime mocktail is gonna knock your socks off. It only takes a few simple steps to make too! Here’s how to do it:

Add the diced watermelon and lime juice to your blender. Pulse, and then blend on high until smooth.

Place a fine strainer over a bowl, and pour the watermelon lime juice through it. This removes excess pulp and helps make the drink smooth to ensures there isn’t any gritty texture, but you can definitely skip this step if you’d like.

Muddle the mint leaves in a small pitcher, and then pour watermelon juice into the pitcher. When you’re ready to serve this easy watermelon mocktail, fill your glasses halfway with ice. Pour the watermelon lime juice over the top of the ice until the glass is 2/3 full.

All that’s left to do is to top off each glass with seltzer and garnish with a slice of lime and a sprig of fresh mint. Serve it with a straw, and if you’re feeling fancy, a little umbrella.

How to Store Watermelon Mocktail

For best results, store the watermelon juice separately from the seltzer. You can store the watermelon lime juice in a pitcher or mason jar for up to 2 days. When you’re ready to serve, give it a shake and then add it to a glass with ice and seltzer and enjoy!

What to Serve with a Watermelon Mocktail

Once you’ve got your drink in hand, just sit down on a comfy chair next to someone you like and sip away! Oh, and I recommend serving it with some homemade tortilla chips and corn salsa. For cocktail hour, an easy appetizer like blue cheese stuffed olives would be great.

It’d also be a tasty drink to serve alongside meals like Instant Pot coconut lime chicken or zucchini taco boats. For a nice, summery meal serve it with Hawaiian burgers or even some chicken fajita tacos.

Tips for Success

This easy mocktail will turn out great with these few simple tips:

  • For a smoother drink, strain the blended watermelon through a fine mesh strainer or cheesecloth. This will help remove the excess pulp and make your drink smooth and delicious!
  • Choose a ripe watermelon for the best flavor. An unripe watermelon will make this mocktail pretty flavorless.
  • Don’t have a muddler? Then use the end of a wooden spoon or a rolling pin to muddle the mint instead.

    I made this and made a small change… I blended up a slice of jalapeno with the watermelon. It was awesome!
