How to Make Watermelon Lemonade Recipe

Step 1: Blend the Watermelon

Start by tossing your diced watermelon into a food processor or blender with 2 cups of water. Blend until you achieve a smooth, vibrant pink puree. This step extracts the juice beautifully and captures that lush, fruity flavor essential to this lemonade.

Step 2: Combine Ingredients in a Pitcher

Pour your fresh watermelon juice into a large pitcher, then whisk in the remaining 6 cups of water, freshly squeezed lemon juice, and sugar. Give everything a thorough stir to dissolve the sugar and mix all the flavors. Simple, bright, and ready to enjoy!

Side Dishes

This lemonade pairs wonderfully with grilled foods like chicken skewers or fish tacos. Light salads with feta and cucumber, or even a fresh fruit platter, also complement the drink’s juicy brightness and refresh your palate perfectly.

Creative Ways to Present

Serve this Watermelon Lemonade Recipe in a mason jar or clear pitcher filled with ice and edible flowers for a festive twist. You could even freeze watermelon chunks as natural ice cubes to keep it cold without diluting the flavor. Presentation that’s both pretty and practical—what’s not to love?

Make Ahead and Storage

Storing Leftovers

Keep your Watermelon Lemonade cold in a covered pitcher in the refrigerator for up to 5 days. Make sure to give it a good stir before serving because fresh watermelon juice tends to settle at the bottom over time.

Freezing

If you want to save some lemonade for later, pour it into ice cube trays and freeze. Those cubes can be blended later into frozen watermelon lemonade slushies or used to chill your drink without watering it down.

Reheating

This recipe is best served cold and fresh, so reheating isn’t recommended. Instead, just give it a quick stir after refrigeration to remix the flavors and enjoy a perfectly cold, revitalizing drink.

FAQs

Can I use frozen watermelon for this recipe?

Absolutely! Frozen watermelon works well and can actually help chill your drink even more. Just thaw it slightly to make blending easier and you’ll still get that sweet, juicy flavor.
How can I make this Watermelon Lemonade less sweet?

You can reduce or skip the added sugar if your watermelon is naturally very ripe and sweet. Additionally, adding a bit more lemon juice will give a tangier, more balanced taste.
Is it necessary to strain the watermelon juice?

Straining is optional! Leaving the pulp adds wonderful texture and fiber, but if you prefer a clear, smooth lemonade, a fine mesh strainer will do the trick.
Can I make this recipe vegan or gluten-free?

Yes, this Watermelon Lemonade Recipe is naturally vegan and gluten-free since it uses only fruit, water, and sugar. It’s a safe and refreshing choice for almost any diet.
