So, this watermelon smoothie recipe is insanely delicious, but there’s not a whole lot to say about it. Sp let’s just talk about watermelon. 

Do you like it?

Watermelon has never been my favorite fruit, but it’s growing on me quickly. It’s the base of my hydrating fruit salad, but I’m also loving it sprinkled with a little bit of Trader Joe’s chili lime seasoning. (If you haven’t tried it that way yet, you need to. It’s so ridiculously good!)

I also really like cocktails with a watermelon base, which inspired me to see how it would work as a smoothie. The answer is very, very well!

What you’ll love about this watermelon smoothie recipe:

  • Delicious watermelon and strawberry flavor
  • Made without any banana or yogurt!
  • Naturally dairy-free, gluten-free, and vegan

Watermelon Smoothie Ingredients

I kept this smoothie recipe simple because I wanted the melon to be the star of the show and not have a bunch of other flavors competing with it. The result is a super refreshing smoothie, with a very pronounced watermelon flavor.

To make it, you’ll need:

Watermelon. Duh. Seedless watermelon is the way to go here for the best texture. Here’s a handy guide about how to cut a watermelon.

Frozen sliced strawberries. Froze strawberries thicken the smoothie up and give it that milkshake-like consistency that I love. The berries also add a little bit of sweetness without overpowering the watermelon flavor.

Lime juice. Some fresh lime juice balances everything out and keeps this watermelon smoothie from being too sweet.

Unsweetened coconut milk. A splash of coconut milk (or almond milk) rounds it out and transforms it into creamy deliciousness.

As is, this refreshing watermelon smoothie recipe is perfect with your breakfast, as a cool mid-afternoon treat, or to enjoy as a healthy dessert.

(For something a little more adventurous, you can also blend in some rum or rosé and a few extra ice cubes. I won’t tell.)

Do You Have A Favorite Blender? 

Any high-powered blender is good. I particularly like my miniature vitamix a lot, but for day-to-day smoothie making I also really love my nutribullet! It’s a compact but powerful appliance that doesn’t take up too much counter space.

Can You Make Smoothies Ahead Of Time? 

Because these watermelon smoothies are more of a slush, they won’t keep in the refrigerator. You can save time in the morning though by freezing them ahead of time as smoothie freezer packs! Pull a pack from the freezer in the morning, blend it up, and start sipping.

Are watermelon smoothies healthy?

Yes! Smoothies are a great way to get lots of nutrients into your diet in one easy step. These watermelon smoothies are particularly hydrating, too!
