Watermelon is made up of more than 90 percent water! This is what makes it so refreshingly juicy. Because of this, you don’t even need a liquid base for your watermelon smoothie. The watermelon IS the liquid!

Key Ingredients:

This watermelon smoothie for weight loss combines watermelon, strawberries, and lime for a sweet-tart flavor!

Frozen banana – Frozen banana naturally sweetens and thickens the smoothie. I always keep frozen bananas at the ready. Just peel and slice a banana, transfer to a zip-top bag, and freeze overnight. I usually freeze two at a time so I know I’ll have plenty.

Frozen strawberries – Strawberry and watermelon are a truly sweet combo! Be sure to use frozen strawberries so the smoothie is thick enough.

Greek yogurt – For a boost of protein and creaminess. I prefer unsweetened to avoid excess sugar, but you can use sweetened too! Or swap the Greek yogurt with a dairy-free alternative.

Fresh watermelon – For best results, use peak-season ripe watermelon! If your watermelon isn’t ripe, the smoothie won’t taste sweet enough. Look for a watermelon with a deep yellow-orange field spot.

Lime – Citrus makes the watermelon flavor pop! Always buy fresh limes.

How to Make a Watermelon Smoothie:

Smoothies are super simple! Here’s what you need to do:

Combine ingredients: In the pitcher of a high-speed blender, combine the frozen banana chunks, frozen strawberries, fresh watermelon, Greek yogurt, and a fresh squeeze of lime juice.

Blend: Blend until thick, creamy, and smooth.

Adjust and serve: I like my smoothies on the thick side. If you like them a bit thinner, add a splash of water and blend again. Pour into a glass and enjoy immediately!

Recipe Tips:

  • Don’t add liquid. Watermelon turns to liquid once it’s blended. Blend first, then add liquid if necessary. I liked the consistency so I didn’t add any.
  • Freeze bananas ahead of time. I always keep frozen bananas in the freezer. They’re cheap and great for smoothie bowls. Remember to freeze a banana the night before you plan to make this smoothie.
  • Use a high-speed blender. High-speed blenders have powerful motors that give you a creamier blend. A Ninja is an affordable option and works great!

  • Watermelon spinach smoothie – Add a handful of baby spinach for a boost or iron and feel-good nutrients.
  • Make it vegan – Swap the Greek yogurt with vegan yogurt.
  • Sweetener – I prefer the sweet tart flavor, but you can make yours sweeter if desired! Add a teaspoon or two of honey, maple syrup, or light agave.

Storage Tips:

I don’t recommend storing smoothies. Technically, you can store them in the fridge for 24 hours, but they lose their frosty texture.

Instead, I recommend freezing any leftover smoothie in a popsicle mold. Add popsicle sticks, freeze overnight, and enjoy refreshing smoothie pops on a hot summer day!
