Easy & Refreshing 2-Ingredient Watermelon Smoothie

Watermelon Smoothie is a creamy and velvety smoothie, prepared without added sugars with only frozen fruit and fresh milk. It is a summer drink that, like all smoothies, can be made in many different ways, perhaps replacing the milk with Greek yogurt or adding a sweetener of your choice, such as honey, erythritol or cane sugar.

We opted for an ultra light version, perfect even for those who are watching their figure: after cutting the watermelon pulp into cubes we transferred it to the freezer, covered with cling film, for about 2 hours; in this way the final result will be dense and frothy without the need for further preparations. Once ready, all you have to do is pour the smoothie into individual glasses, garnish it with a slice of watermelon and a sprig of mint, and then sip it for breakfast or as a snack for a light and thirst-quenching break.

What is Watermelon Smoothie?

The history of watermelon smoothies ties closely to the global appreciation for watermelon as a hydrating and refreshing fruit, especially in tropical and Mediterranean climates. In countries like India, Mexico, and across Southeast Asia, watermelon has been blended with local ingredients like mint, lime, and sugar for centuries to create cooling beverages during the hot seasons. These early forms of smoothies were often made without dairy, relying instead on the fruit’s natural juices and sometimes mixed with spices or herbs, giving rise to regional variations of watermelon-based drinks that were both nutritious and deeply refreshing.

In the United States, the popularity of watermelon smoothies began to rise alongside the health food movement of the late 20th century. As blenders became household staples and Americans grew more health-conscious, fruit smoothies gained traction for their convenience and nutritional value. Watermelon, with its high water content, natural sweetness, and rich lycopene content, became a favored base for summer smoothies. Often paired with other fruits like strawberries or citrus, or enhanced with yogurt, mint, or honey, watermelon smoothies evolved into a staple of American summer menus—from beachside cafes to fitness-focused juice bars.

Pro Tips for The Best Watermelon Smoothie

• Ensure the watermelon is fully ripe for the sweetest and juiciest flavor. Choose a melon that feels heavy for its size and has a deep, hollow sound when tapped.
• A squeeze of lime juice brightens the flavor and balances the sweetness of the watermelon. You can also try adding a little lemon zest for extra zing.
• A powerful blender will help you achieve a smooth, creamy consistency, ensuring there are no chunks or fibrous bits in your drink.
• If your watermelon is very watery, you can blend it in stages, starting with the solids and gradually adding liquids to reach your desired texture.

What Fruits Go Well With Watermelon For The Smoothie?

Fruits that pair beautifully with watermelon in a smoothie include strawberries, blueberries, pineapple, mango, and citrus fruits like oranges or lemons. These fruits enhance the watermelon’s sweetness while adding tang, tropical flavors, or a hint of acidity that balances the overall taste.

Can I Use Frozen Fruits?

Yes, you can use frozen fruits in your watermelon smoothie. Frozen fruits, like strawberries, mangoes, or pineapple, will help thicken the smoothie and make it colder without the need for ice, while still retaining their flavor and nutrients. Just make sure to adjust the liquid ratio as frozen fruits might make the smoothie thicker.

How To Serve Watermelon Smoothie

Watermelon smoothies are best served chilled in tall glasses. For an extra touch, garnish with a few fresh mint leaves, a slice of lime, or even small watermelon cubes on the rim. You can also serve it in a mason jar or a fun, decorative glass to add a festive feel for summer gatherings or brunches.

Can I Make It Ahead of Time?

Yes, you can make a watermelon smoothie ahead of time. To preserve its freshness, store it in an airtight container in the fridge for up to 1–2 hours. If you want to prepare it further in advance, consider freezing the smoothie in ice cube trays or a sealed container. When ready to serve, blend the frozen smoothie for a quick, refreshing treat.

Does It Freeze Well?

Yes, watermelon smoothies can freeze well. To do so, pour the smoothie into an airtight container or ice cube trays and freeze. Once frozen, you can blend the cubes back into a smoothie when you're ready to enjoy it. Keep in mind that the texture may change slightly after freezing, but it will still taste refreshing.

How to Store Any Leftovers

To store leftover watermelon smoothie, transfer it to an airtight container and refrigerate it for up to 1–2 days. If the smoothie separates, simply give it a good stir before serving.

How to Make Watermelon Smoothie

Cut the watermelon into slices, peel it and remove the seeds, then cut the pulp into cubes: keep a couple of slices aside for finishing.
