Ingredients You Will Need
Here’s what you’ll need to make the Tropical Smoothie Cafe Watermelon Mojito Recipe:
- Yellow lemon (½): The lemon adds a sharp, citrusy note to the drink, which helps balance the sweetness of the watermelon and sugar.
- Watermelon (15-20 cubes): Watermelon is juicy and sweet, and it makes the base of this mojito. It’s hydrating and the perfect summer fruit.
- Fresh mint leaves (14-15 leaves): Mint brings that cool, fresh flavor that works perfectly in a mojito.
- Sugar (2 tsp): Sugar is optional, but it helps bring out the sweetness in the watermelon.
- Ice cubes (½ glass): Ice helps chill the drink and gives it that perfect refreshing touch.
- Fresh lime (2 slices): Lime adds a tangy flavor and gives a citrusy zing to the drink.
- Fresh mint leaves (2-3 leaves): Extra mint is used for garnish to give the drink a nice, aromatic touch.
- Club soda (⅓ of glass): The club soda gives the drink a fizzy, bubbly texture that makes it even more refreshing.
Helpful Swaps
- Sugar Alternative – You can replace sugar with honey or agave syrup for a healthier option.
- Club Soda – If you want a less sweet drink, use sparkling water instead.
- Mint Substitutes – If fresh mint isn’t available, use mint syrup or a few drops of mint extract (but use sparingly!).
Kitchen Appliances You’ll Need
To make this drink, you don’t need much equipment. Here’s what you’ll need:
- A muddler: This helps crush the mint, lemon, and watermelon to release all the flavors. If you don’t have one, you can use the back of a spoon.
- A glass: For mixing and serving your mojito.
- A stirring spoon: To mix the ingredients together before adding the soda.
- A knife: For cutting the watermelon and lemon into pieces.
How to Make the Tropical Smoothie Cafe Watermelon Mojito
Making this watermelon mojito is super easy, and you can follow these simple steps to recreate the Tropical Smoothie Cafe version right in your kitchen.
Step 1 | Cut the lemon into small pieces

Step 2 | Add the lemon pieces to the glass
Place the lemon pieces into your glass to get that citrusy zing in your drink.

Step 3 | Add watermelon cubes
Next, add around 15-20 watermelon cubes to the glass. Watermelon brings sweetness and hydration to the mix.

Step 4 | Add fresh mint leaves
Add 14-15 fresh mint leaves into the glass. These will give the drink its cool, refreshing flavor.

Step 5 | Add sugar
If you like it a little sweeter, add 2 teaspoons of sugar. You can adjust this based on your sweetness preference.

Step 6 | Muddle the mixture
Using your muddler, gently mash the lemon, watermelon, mint, and sugar together. This releases all the juices and flavors.

Tips for Making Perfect Watermelon Mojito
After making this drink many times, I’ve learned some tricks that help make it perfect every time:
- Choose the right watermelon: Tap the watermelon – it should sound hollow. Look for a yellow spot where it sat on the ground – this means it ripened on the vine. The riper your watermelon, the sweeter your mojito will be.
- Chill your ingredients: I like to refrigerate my watermelon and club soda beforehand. Cold ingredients make a colder drink that stays refreshing longer.
- Don’t over-muddle the mint: Press gently when muddling mint leaves. If you muddle them too hard, they release bitter compounds that can ruin the taste of your drink.
- Use the right amount of ice: Too little ice and your drink won’t be cold enough; too much and it will dilute quickly. I find that filling half the glass works perfectly.
- Make it ahead (partially): If you’re serving these at a party, you can muddle the watermelon, mint, sugar, and citrus ahead of time and keep it refrigerated. Just add ice and club soda when you’re ready to serve.
How to Serve this Drink
Serving this watermelon mojito the right way makes it taste even better! Here’s how I like to serve it:
- Glass choice: I prefer tall glasses that hold at least 12 ounces. Mason jars work great too and give a rustic feel. For fancy occasions, I use hurricane glasses or highball glasses.
- Temperature: Serve this drink very cold! I sometimes chill the glasses in the freezer for about 10 minutes before making the drink.
- Serving time: I find watermelon mojito tastes best right after making it, when the club soda is still bubbly and the ice hasn’t melted too much.
- Presentation: Place the drink on a coaster and add a colorful paper straw. If you’re serving guests, arrange the drinks on a tray with extra mint sprigs and watermelon slices on the side.
- Timing: This drink is perfect for mid-afternoon or early evening when the sun is still out but starting to go down. There’s something about the golden hour light shining through a pink watermelon mojito that makes summer feel magical!
What to Eat with Watermelon Mojito
Pairing food with this refreshing drink makes for a complete experience! Here are my favorite foods to serve with watermelon mojito:
- Light appetizers: Cucumber sandwiches, hummus with pita chips, or bruschetta pair perfectly with this drink. The lightness of these snacks complements the refreshing quality of the mojito.
- Grilled foods: I love serving watermelon mojito at barbecues. The cool drink balances the smoky flavor of grilled chicken, shrimp skewers, or vegetable kebabs.
- Fresh salads: A summer salad with mixed greens, feta cheese, and vinaigrette dressing tastes amazing alongside this drink. I especially love arugula salad with watermelon chunks and balsamic glaze.
- Spicy dishes: The cooling effect of watermelon and mint balances spicy foods beautifully. Try serving this drink with spicy tacos, buffalo wings, or Thai food.
