What Ingredients are in Refreshing Watermelon-Cucumber Smoothie?
This watermelon-cucumber smoothie combines the hydrating power of summer’s favorite fruit with the cool crispness of cucumber for an absolutely perfect hot-weather beverage. The ingredient list is invigoratingly simple, making this an easy go-to when temperatures rise. I love how these flavors work together to create something that tastes far more sophisticated than the sum of its parts.
- 2 cups watermelon (preferably frozen for a thicker smoothie)
- 1/2 cup cucumbers
- 3 tablespoons whole milk
- 1 tablespoon honey
- 1/2 lime, juiced
- 1-2 tablespoons water (optional, to adjust consistency)
- Cucumber slice for garnish (optional)
When shopping for these ingredients, quality really matters. Look for a sweet, ripe watermelon with a deep red interior for the best flavor and color. For cucumbers, English or Persian varieties work wonderfully as they’ve fewer seeds and a milder flavor. The honey is technically optional if your watermelon is particularly sweet, but I find it helps round out the flavors. Oh, and while the recipe calls for whole milk, you could easily substitute plant-based alternatives like almond or oat milk if you prefer a dairy-free version.
How to Make this Refreshing Watermelon-Cucumber Smoothie
Making this smoothie couldn’t be simpler, and that’s exactly what we want when the temperature climbs and cooking anything feels like torture. Start by gathering your blender and all your ingredients.
Add 1/2 cup of sliced cucumbers to the blender, followed by 3 tablespoons of whole milk (though the recipe actually calls for buttermilk in the instructions, which gives a pleasant tanginess), 1 tablespoon of honey (skip if your watermelon is super sweet), and the juice from 1/2 lime. These ingredients create the base of our smoothie with the cucumber providing that cool, invigorating quality we’re after.
Next comes the main event: 2 cups of watermelon, preferably frozen for that perfect smoothie thickness. But here’s a little trick—don’t dump all the watermelon in at once.
Blend the cucumber mixture until smooth, then add half your frozen watermelon and blend again. You might need to stop occasionally to push everything down with a spatula or wooden spoon, ensuring everything gets properly incorporated.
Once that’s looking good, add the remaining watermelon and continue blending until you achieve that perfect smooth consistency. If things are looking a bit too thick, add 1 to 2 tablespoons of water to thin it out.
Finally, pour this vibrant pink concoction into a glass, garnish with a cucumber slice if you’re feeling fancy, and prepare to be transported to a beachside cabana, even if you’re just sitting at your kitchen counter.
Refreshing Watermelon-Cucumber Smoothie Substitutions and Variations
While our basic watermelon-cucumber smoothie recipe is already a summer showstopper, let’s explore some creative ways to customize it to your taste preferences or whatever ingredients you happen to have on hand.
Don’t have buttermilk? Regular yogurt or coconut milk work beautifully. Prefer things sweeter? Try agave instead of honey, or skip the sweetener entirely if your watermelon is particularly ripe.
Mint leaves add a revitalizing twist, and a splash of coconut water lightens the texture. For a creamier version, toss in half an avocado.
Want something more substantial? A scoop of vanilla protein powder transforms this into a post-workout treat.
What to Serve with Refreshing Watermelon-Cucumber Smoothie
Pairing options for your watermelon-cucumber smoothie can turn a simple beverage into a complete meal or snack experience.
I love serving mine with a light Mediterranean mezze platter—think hummus, warm pita, and olives. The smoothie’s cooling properties complement spicy foods beautifully, so why not try it alongside some jalapeño avocado toast?
For breakfast, pair it with Greek yogurt topped with granola and berries. The tangy yogurt balances the smoothie’s sweetness.
Sometimes, simplicity wins—a handful of roasted almonds or a small cheese board works wonderfully.
