Why You Will Love This Recipe
- Ready in 5 minutes. Just toss everything in one blender and go. There's no prep work and no cooking.
- Naturally sweet. The fruit does all the work, so the sweetener is optional.
- Customizable. Make it with plant milk and your choice of yogurt to keep it dairy-free or make a few swaps to use what you have on hand.
- So versatile. You can enjoy it for breakfast, a snack, or even a light dessert.
Ingredients

- Frozen Fruit: This smoothie uses a combination of frozen watermelon, fresh or frozen strawberries, and frozen mango. Frozen fruit works best (especially for the mango and watermelon) as they give the smoothie its texture without needing to add ice. I also use them to make these chia frozen fruit overnight oats.
- Milk: This smoothie works great with any type of dairy or dairy-free milk. I prefer soy milk when keeping it dairy-free because it's high in protein, but you can use any milk you like, such as whole milk, low-fat milk, coconut milk, almond milk, etc.
- Flavor: Fresh lime juice balances the sweetness with a bit of tang, while mint adds an extra kick of freshness.
- Yogurt: I like to use Bulgarian yogurt because it's tangy and well fermented. However, Greek, soy, or coconut yogurt all work too, so feel free to use your favorite. Plain soy yogurt is the best dairy-free option because it is thick and a better source of plant-based protein.
- Sweetener: The sweetener is only needed if your watermelon isn't that sweet or if you prefer your smoothie a bit sweeter. My top choice for adding more sweetness is maple syrup, but you can also use honey, agave, or any other sweetener you have on hand.

How to Pick a Good Watermelon
This is honestly where the smoothie really lives or dies! A bland watermelon makes a bland smoothie, no matter how ripe your mango is.
And keep in mind, watermelon doesn't ripen any further once it's picked, so what you buy is what you get. It's worth taking an extra minute in the store to choose well.
Here's what I look for:
- Check the field spot. This is the patch on the watermelon where it sat on the ground. You want it creamy yellow, not white or pale - the deeper and more golden it is, the sweeter your melon will be.
- Give it a knock. Tap it with your knuckles. A ripe watermelon sounds deep and hollow, almost like a drum. If it sounds dull or flat, keep looking.
- Pick it up. Grab a couple of similar-sized melons and go with the heaviest one - that extra weight means it's packed with juice.
- Check the stem. Look for a stem that is brown and dry, not fresh and yellow. This means the watermelon has ripened on the vine and wasn't picked up too early.
Variations and Substitutions
- Lime zest. Add the lime zest from your lime for more kick.
- Banana: For a similar consistency and sweetness, use frozen banana in place of the mango.
- Protein powder. Add 1 scoop of protein to make this smoothie more filling. Just be sure to choose a protein powder that has a mild flavor and isn't too strong, like vanilla.
- Hemp seeds. I love adding up to 2 tablespoons of hemp seeds for extra protein and some healthy fats. Using a full 2 tablespoons adds 6g of protein.
- Coconut water. Swap it in for the milk if you want an even fresher, more hydrating smoothie.
- Dates. Prefer a whole-food sweetener over a liquid one? Add 1-2 dates - they do wonders here.
- Basil. Out of mint? Basil makes a surprisingly great substitute.
How to Make a Watermelon Mango Smoothie

- Step 1: Add all of the ingredients to a high-speed blender, starting with the milk first.

- Step 2: Blend on high until smooth and creamy.
Blending Tip: If your blender is struggling with the frozen fruit (especially the watermelon), let it sit out on the counter for about 10 minutes before blending. The fruit softens just enough to blend smoothly, and you'll still get a nice cold smoothie.

- Step 3: Give the smoothie a taste and adjust the flavor as needed. Add more mint for freshness, more lime juice for tang, or more milk if it's too thick for you. Pour into a glass.

- Step 4: Garnish the glass with mint leaves, watermelon slices, and/or lime wedges. Enjoy it for a quick on-the-go breakfast.
👩🍳Petra's Top Tips
- Use a ripe, sweet watermelon. This is the single biggest thing that affects the flavor of your smoothie. Be sure to check out the "How to Pick a Good Watermelon" section above for exactly what to look for.
- The sweetener is optional. Add it only if your watermelon isn't very sweet, or if you just like your smoothies on the sweeter side. Taste as you go and adjust from there.
- Freezing watermelon ahead of time? Cube the watermelon, spread the pieces on a parchment-lined plate, and freeze for about 2 hours until solid before transferring to a freezer bag. Freezing on a plate first keeps the cubes from clumping into one big block.
- Storage Tips: Pour the smoothie into a glass jar, seal it, and store in the refrigerator for 1-2 days or freeze it for up to 3 months. Thaw overnight in the fridge before serving. You may need to reblend it to restore the texture.
Watermelon Mango Smoothie Recipe FAQs
Watermelon goes well with many fruits, such as strawberries, bananas, and tropical fruits like pineapple and mango. Citrus fruits like oranges and limes balance out the sweetness of the watermelon by bringing tang and some sourness.
Watermelon is mostly water, so it doesn't add much thickness on its own, even when frozen. If your smoothie comes out thinner than you'd like, make sure your watermelon and mango are both frozen solid before blending because that's where most of the consistency comes from. You can also cut back on the milk slightly, or add a few extra ice cubes or a frozen banana to thicken things up.
Serving Suggestions
This mango watermelon smoothie is perfect any time of day! Enjoy it for breakfast with this eggless baked oats or as a treat with a fluffy lemon muffin with blueberries.
It's also a great way to stay hydrated in the summer. I love to sip on it while snacking on some creamy guacamole (with no cilantro!) and chips.
