Ingredients

Gather ’round, let’s talk about the goodies you’ll need. These simple ingredients come together to create something magical!

4 cups cubed watermelon: Look for a nice, ripe one! Seedless makes your life way easier. These juicy cubes are the star!
1 cup sliced strawberries: A little sweet and slightly tangy counterpoint. Pick ones that are bright red and fragrant.
1/2 cup fresh blueberries: Little pops of juicy flavor and beautiful color.
1 cup cubed cucumber: My secret weapon for extra hydration and a wonderful, cool crunch. Use an English cucumber if you don’t like big seeds.
1/4 cup fresh mint leaves, chopped: Please, please use fresh mint! It makes all the difference. That clean, cool flavor is essential to the dressing.
Juice of 1-2 limes (to taste): Start with one, taste, and add more if you like it super zesty! Freshly squeezed is a must here.
Zest of 1 lime: Don’t skip this! The oils in the zest add so much vibrant lime flavor. Just be careful not to get the white pith.
1-2 tablespoons keto-friendly sweetener (optional, to taste): This is totally up to you and how sweet your fruit is. Erythritol, xylitol (be careful if you have pets, xylitol is toxic!), or a monk fruit blend work great. Taste the dressing before adding!
Pinch of salt: Trust me on this. A tiny bit of salt enhances all the sweet and tangy flavors. It won’t make it salty, just more flavorful.

How to Make It

Alright, let’s get this party started! It’s super simple, I promise.

First things first, grab your biggest bowl. You want plenty of space to mix everything without making a mess. Gently combine your beautifully cubed watermelon, those lovely sliced strawberries, the happy little blueberries, and the cool, crisp cucumber cubes. Look at all those colors!
Now, let’s make that magical dressing! In a separate, smaller bowl, whisk together the fresh lime juice, the fragrant lime zest, your finely chopped fresh mint leaves, the optional keto-friendly sweetener (if you’re using it), and that little pinch of salt. Give it a good whisk until everything is combined. Give it a quick taste! Does it need more lime? A tiny bit more sweetness? Adjust it to your liking.
Time for the shower! Pour that gorgeous green dressing evenly over the fruit and vegetable mixture in the large bowl.
Now, the gentle part. Using a large spoon or rubber spatula, gently toss everything together. You want every single piece of fruit and cucumber to get a lovely coating of that zesty, minty dressing. Be kind to the fruit so it doesn’t get mushy!
This next step is crucial for flavor town! Cover the bowl and pop it in the refrigerator for at least 20-30 minutes. This chilling time isn’t just to make it cold; it allows all those amazing flavors from the dressing to meld with the juices from the fruit. It makes a huge difference! I honestly think an hour is even better if you have the time.
When you’re ready to serve, give it one last gentle toss and serve it up cold!

Substitutions & Additions

Want to mix things up? This recipe is super flexible! Here are a few ideas:

Other Berries: Swap out some strawberries or blueberries for raspberries or blackberries if you like. They are also lower in carbs.
Add Some Creaminess: A sprinkle of crumbled feta cheese adds a salty, tangy contrast that is surprisingly delicious with watermelon and mint. A few cubes of avocado could also work for healthy fats and creaminess, but add them right before serving to prevent browning.
Different Herbs: Not a huge mint fan? Fresh basil is also fantastic with watermelon!
A Little Heat: A tiny pinch of chili powder or a finely minced jalapeño could add a fun kick!
Boost the Flavor: A splash of orange blossom water or rose water could add an exotic twist.

Tips for Success

Making this salad is pretty foolproof, but here are a couple of things I’ve learned along the way:

Choose Ripe, Firm Fruit: You want sweet fruit, but not overly ripe fruit that will turn mushy when tossed.
Fresh is Best for Mint & Lime: Bottled juice and dried mint just won’t give you the same vibrant, fresh flavor that makes this salad special.
Taste the Dressing: Don’t be shy! The sweetness of fruit varies, and so does the tartness of limes. Adjust the lime juice and sweetener before pouring it over the fruit.
Don’t Skip the Chill Time: Seriously, those 20-30 minutes (or more!) in the fridge are essential for the flavors to really come together.
Prep Ahead: You can definitely chop all your fruit and cucumber ahead of time and store them in an airtight container in the fridge. Make the dressing in a separate container. Combine them about an hour before you plan to serve.

How to Store It

Keep any leftovers (if there are any!) in an airtight container in the refrigerator. It’s best enjoyed within 2-3 days. After that, the fruit starts to release a lot of liquid, and while it’s still edible, it can get a bit watery. But honestly, it’s so good, I doubt it will last that long!

FAQs

Got questions? I’ve got some quick answers!

Is this salad really keto-friendly? Yes! Watermelon and berries are lower in carbs compared to many other fruits, and cucumber and the dressing ingredients are low carb. Portions still matter on a keto diet, but this is a fantastic, refreshing low-carb option.
Can I use frozen fruit? I wouldn’t recommend it for this recipe. Frozen fruit releases a lot of water as it thaws, which will make your salad watery and mushy. Fresh is definitely the way to go here.
What if I don’t have fresh mint? You could try using fresh basil, which pairs beautifully with watermelon. Dried mint won’t work well in this dressing.
Do I have to add sweetener? Nope! If your fruit is super ripe and sweet, you might find you don’t need any added sweetener at all. Always taste the dressing before adding it to the fruit.

Notes

Choose ripe, firm fruit to prevent mushiness. Use fresh mint and limes for the best flavor. Always taste the dressing before adding it to the fruit and adjust sweetener/lime as needed. Don't skip the chill time – it's essential for flavor. You can prep fruit/cucumber and dressing separately ahead of time and combine about an hour before serving. Store leftovers in an airtight container in the refrigerator for up to 2-3 days; it may become watery over time. Frozen fruit is not recommended as it releases too much water. Substitutions/Additions: Try other berries like raspberries or blackberries. Add crumbled feta cheese or avocado (add avocado just before serving). Fresh basil can replace mint. A pinch of chili powder or minced jalapeño can add heat. A splash of orange blossom water or rose water adds an exotic twist.
