Watermelon Smoothie Recipe with Strawberries

This watermelon smoothie is one of the easiest ways to turn sweet summer watermelon into a cold, refreshing drink. It's made with frozen watermelon, strawberries, banana, and a splash of lemon or lime juice for a smoothie that's fruity, bright, and naturally icy.

There's something about watermelon in summer that always feels a little nostalgic - cold slices from the fridge, sticky fingers, and that sweet, juicy crunch on a hot day. This watermelon smoothie takes that same summer flavor and turns it into a quick, refreshing drink.

Freezing the watermelon first is the little trick that makes all the difference. It gives the smoothie a naturally icy, almost slushy texture without needing to add ice, while the banana and strawberries make it smooth, fruity, and just creamy enough.

How to Make a Watermelon Smoothie

Freeze the watermelon

• Cut the watermelon into cubes and freeze them in a single layer on a parchment-lined baking sheet for at least 4 hours or overnight.

Chef's Tip: Freezing the watermelon in a single layer helps prevent large clumps and makes blending much easier later.

Add the ingredients to the blender

• Add the lemon or lime juice first, followed by the banana. Top with the frozen strawberries and watermelon cubes.

Chef's Tip: Layering ingredients helps the blender work more efficiently. Start with liquids, then softer ingredients, and finish with frozen fruit.

Blend

• Begin blending on low speed, then gradually increase to high speed until smooth and creamy.
• If the smoothie is too thick, add a small splash of water to help it blend.

Taste and adjust

• Taste the smoothie and add honey or maple syrup if desired. Blend briefly again to combine.

Serve

• Pour the smoothie into glasses and serve immediately.

Chef's Tip: Frozen watermelon gives the smoothie a naturally icy texture without needing extra ice.

Flavor Variations, Substitutions and Add-Ins

This frozen watermelon smoothie is easy to adapt depending on what you have in the freezer or what flavor you're in the mood for.

• Make it creamy - Add a few spoonfuls of Greek yogurt, coconut yogurt, or plain yogurt before blending.
• Make it tropical - Add frozen pineapple or mango for a bright tropical twist.
• Add fresh herbs - A few mint or basil leaves make this smoothie extra refreshing.

What to Serve with a Watermelon Smoothie

This watermelon smoothie is light, fruity, and refreshing, so it works beautifully as part of a summer breakfast, brunch, or healthy afternoon snack.

• For kids and warm-weather treats - Serve it with mini muffins, fruit skewers, homemade popsicles, peanut butter toast, or simple cheese and crackers for an easy summer snack.

Storage Instructions
