Watermelon Smoothie

The second the temperature climbs above 90 degrees, I start craving one thing: watermelon. It’s juicy, refreshing, naturally sweet, and somehow makes even the hottest summer day feel a little more manageable.

This watermelon smoothie is my go-to when I want to cool off, stay full, and keep working toward my health goals without overthinking it. Blended with simple, nourishing ingredients, it tastes like a summer treat while still delivering the hydration, fiber, and protein. This is my favorite smoothie to make on repeat all summer long.

Why You’ll Love It

Summer is overflowing with nutrient-dense produce. Take advantage of these ruby red, antioxidant-rich ingredients!

• Ready in 5 minutes. Toss everything in the blender, hit blend, and you’re sipping a refreshing smoothie in less time than it takes to slice the fruit. You can also check out my recommended smoothie blenders for the creamiest results.
• Hydrating and refreshing. Watermelon’s high water content helps support hydration, while lime adds a crisp, citrusy finish that keeps each sip light and energizing.
• Packed with real benefits. Strawberries and cherries bring fiber and antioxidants for heart and immune support, while watermelon delivers lycopene, a powerful antioxidant linked to heart health and cellular protection.

Watermelon Smoothie Ingredients

• Watermelon (fresh, chopped). Choose a heavy melon with a creamy yellow field spot for the sweetest flavor. Seedless makes prep quicker, but either works. This is how I cut melon.
• Strawberries (fresh or frozen). Look for bright red berries with green tops and no white shoulders. If using fresh, freeze extras at peak ripeness for future smoothies, or portion them into frozen meal prep smoothie packs so they’re ready to blend anytime.
• Cherries (fresh or frozen). Deep red cherries are usually the sweetest and richest in antioxidants. If buying fresh, pit and freeze them on a sheet pan so they’re ready to blend.
• Lime (fresh, peeled). Pick a lime that feels heavy for its size and has a slight give when squeezed. Lime adds a little zest and bite to make it extra refreshing.
• High-quality protein: Blend in chia seeds and collagen peptides for a protein boost along with some healthy omega-3’s and fiber to create a balanced smoothie.

How to Make a Watermelon Smoothie

1. Add ingredients to the blender. Place the chopped watermelon, frozen strawberries, frozen cherries, peeled lime, plant-based protein powder (if using), and chia seeds into a high-speed blender.
2. Blend until smooth. Blend on high until the smoothie is completely smooth and creamy. Add a splash of water if needed to help it blend.
3. Serve and enjoy. Pour into glasses and sprinkle extra chia seeds on top, if desired. Sip right away for the freshest flavor and best texture.

Recipe Tips

1. Since watermelon is over 90% water by weight, you don’t need to add any extra liquid or ice to this smoothie.
2. Use seedless watermelon for this recipe. No need to spend all day picking out watermelon seeds!
3. Using frozen cherries and frozen strawberries rather than fresh ones yields a cool and frosty drink. If using fresh, add ice cubes to the blender.
4. Serve this smoothie immediately after making it. The longer it sits, the more the watermelon separates from the other ingredients.
