Ingredients

To make this creamy, hydrating smoothie, you’ll need just a handful of ingredients:

3 cups seedless watermelon, cubed (use chilled or frozen for a frostier texture)
1 banana (optional, but adds natural sweetness and a creamy consistency)
1 tablespoon lime juice, freshly squeezed
½ cup yogurt (optional – use plain, Greek, or plant-based if dairy-free or vegan)
A few fresh mint leaves (optional, but adds a delightful herbal freshness)
Ice cubes, as needed for extra chill

Instructions

Prep your ingredients: Cut the seedless watermelon into cubes and remove any stray seeds. If you’re using frozen banana or watermelon, there’s no need for ice.
Add everything to your blender: Combine the watermelon, banana, lime juice, yogurt, mint leaves, and ice cubes in a high-speed blender.
Blend it smooth: Start on low and gradually increase speed. Blend until the mixture is smooth and creamy.
Taste and adjust: If you’d like it more tangy, add a little more lime juice. For added sweetness, a drizzle of honey or a few strawberries works well.
Serve immediately: Pour the smoothie into chilled glasses, garnish with a lime wedge or fresh mint, and enjoy!

Tips and Tricks

Use frozen watermelon cubes to keep it cold without watering it down.
Lime juice brightens the flavor and balances the sweetness.
Add yogurt for a creamier, more filling smoothie.
Try mint or basil for a refreshing herbal note.
Keep blending until silky smooth — watermelon can be pulpy if under-blended.

Variations to Try

Get creative and tailor your smoothie to suit your mood:

Watermelon mint smoothie – add a few extra leaves of mint
Watermelon and coconut water – swap yogurt for coconut water
Watermelon strawberry smoothie – toss in a handful of fresh or frozen strawberries
Spicy version – a pinch of grated ginger or chili flakes for a bold twist
Protein boost – add your favorite protein powder or a spoonful of nut butter

Serve your smoothie in chilled mason jars or tall glasses. Top it with:

Fresh mint or basil
Chia seeds or granola
A lime wedge
A splash of sparkling water for a bubbly version

Storage Tips

Store leftovers in a sealed jar in the fridge for up to 24 hours.
Stir before drinking — natural separation may occur.
Avoid freezing after blending, as the texture can become grainy.

Dietary Flexibility

Vegan – use plant-based yogurt or skip it entirely
Dairy-free – opt for almond, soy, or coconut yogurt
Gluten-free – naturally!
Nut-free – no nuts involved unless added as a topping
