Frozen watermelon margaritas are what I’m making when it’s hot outside and I want something cold, fresh, and dangerously easy to sip. Watermelon can be tricky because if it isn’t sweet, your drink can fall flat, so I walk you through how to balance it with simple ingredients. I’ve shared plenty of party drinks over the years, and the key here is using ripe watermelon and balancing the lime and sweetener so it tastes refreshing, not watered down.

Frequently Asked Questions and Recipe Pro Tips
You can use a whole watermelon or grab pre-cut from the store. I usually go for pre-cut because it’s easy, convenient, and typically seedless, and I love that part.
Just know pre-cut watermelon costs more and doesn’t stay fresh as long since it’s already been exposed to air. Use it soon after buying so it stays sweet and juicy.
If you’re buying a whole watermelon, pick one that feels heavy for its size and sounds deep and hollow when you tap it. Look for a uniform shape too, because odd bumps or dents can mean it didn’t grow evenly and may not be as sweet.
Skip any watermelon with bruises, cuts, soft spots, or big dents. That’s usually a sign it’s past its prime or didn’t have the easiest trip to the store.
Flip it over and look for the field spot, that’s the patch where the watermelon sat on the ground while it grew. You want that spot to be creamy yellow. That’s a good sign the melon had time to ripen and get sweet. If the spot is white or green, it may have been picked too early, and nobody wants to haul home a bland watermelon.
The more liquid you add, the thinner your margarita will be. If you have time you can also freeze the watermelon ahead of time. This will create thick margaritas. I've never seen frozen watermelon in stores, and I almost always forget to freeze it and I end up using fresh.
When using fresh fruit for frozen drinks, be sure to use plenty of ice. Add plenty of ice to the blender to help thicken the margarita. As a general rule of thumb, use about 1 cup of ice for every 1 cup of liquid ingredients.
Make sure you have a powerful blender that can crush the ice and mix the ingredients together smoothly. A blender with high horsepower and sturdy blades is best for making frozen margaritas.
You can store leftover cocktails in the fridge for 3 days. You can blend it again with more ice.
You can easily swap out the fruit in this recipe and make a classic margarita using triple sec, Cointreau, or Grand Marnier. Use 1-2 ounces per cocktail.
The great thing about making your own cocktails is you control how it tastes. If you like sweet drinks add sugar or sweetener to suit what you want. If you like strong drinks use more liquor. You can tailor this drink to suit your needs with no need to rely solely on the recipe.
You can use salt, sweetener (sugar), or Tajin to garnish your glass if you wish.
Pour a small amount of salt, sweetener, or Tajin onto a small plate, making sure that the salt layer is thick enough to cover the rim of the glass.
Take a wedge of lime and run it around the rim of the glass to wet it. This will help the salt/sweetener to stick to the rim.
Hold the glass upside down and dip the rim into the salt/sweetener on the plate, rotating it slightly to make sure the salt covers the entire rim.
Gently tap the glass to remove any excess salt/sweetener.

Made margaritas tonight for friends and loved this recipe! It was so easy to vary based on the groups preferences - I only used the half cup of tequila for the initial mixing and the guests that liked their margaritas a little stronger added a bit more to their individual drinks without making the drink too liquidity! I also gave people the option of a sugar rim or a salt rim depending if they wanted a sweeter drink 🙂 I will definitely be using the notes about how to pick the most flavorful watermelon next time I’m at the store, because I can see myself making these all spring and summer long!
