Refreshing Watermelon Lemonade Slush: Summer Drink Recipe

Icy watermelon lemonade slushies are the perfect refreshment on a hot summer day. Sweet watermelon, bright lemon juice, and just a touch of sugar come together for a cooling treat that’s simple to make and always a crowd-pleaser. Serve it alongside fruit pizzas or a bright berry salad for a festive gathering, or enjoy it with a savory meal like zucchini pizza or a hearty gumbo.

How to Make a Watermelon Slush

Start by cutting a watermelon into 1.5–2-inch cubes. For this recipe you’ll need a total of 10 cups of cubed watermelon: 6 cups frozen and 4 cups refrigerated. Spread the 6 cups of cubes in a single layer on a parchment-lined baking sheet and freeze for at least 4 hours.

When the frozen cubes are ready, pour the lemon juice into the bottom of an 8-cup blender, then add the 4 cups of refrigerated watermelon. Next add most of the frozen watermelon and the sugar. Placing the refrigerated fruit beneath the frozen pieces helps the blender work smoothly. Blend until silky, then add the remaining 2 cups of frozen watermelon and blend again until completely smooth and slushy. Serve immediately.

Instructions

1. Cut and cube 10 cups of watermelon into 1.5–2″ cubes at least 4 hours in advance.

5. Measure the lemon juice into the bottom of an 8-cup blender.
6. Add the refrigerated watermelon next.

Notes

Store leftovers in the refrigerator. If it thaws, drink it as a watermelon lemonade or re-blend with ice or more frozen watermelon to return it to a slushy consistency.
