This watermelon margarita mocktail hits all the right notes when you crave a sunny-day sip that is fruity and perfectly balanced. It is impossibly easy with only four simple ingredients that come together in just a few minutes to make a drink everyone can enjoy.
This one became an instant favorite at our family BBQs. When watermelon is stacked in the fridge and lime is on hand I love whipping up a pitcher of these as a cool-down treat on hot afternoons.
Ingredients
- Cubed watermelon: You want it to be ripe and sweet as the flavor really shines here Look for deep red flesh with minimal white streaks
- Agave syrup: Adds natural sweetness and gives a perfectly smooth finish Use pure agave for best results
- Fresh lime juice: Brings bright citrus punch and keeps things refreshing Choose juicy limes that feel heavy for their size
- Himalayan pink sea salt or Kosher salt: The salted rim creates that classic margarita vibe Use a flaky salt for great texture
Step-by-Step Instructions
- Prepare the glass:
- Run a juicy lime wedge around the edge of your rocks glass until it is slick then place the glass rim side down in a shallow plate of salt Press and twist gently to coat the rim Set the salted glass in the refrigerator to chill and help the salt set firmly
- Muddle the fruit:
- Add the cubed watermelon to a cocktail shaker Pour in the fresh lime juice and agave syrup Now use a sturdy muddler or the end of a wooden spoon to mash everything together Work slowly and firmly so the watermelon releases plenty of juice without splashing
- Strain and serve:
- Place a fine mesh strainer over your prepared glass Add a good amount of ice to the salted glass and carefully double strain the muddled watermelon mix through the strainer into the glass Work slowly so only the juice goes in leaving behind pulp and seeds
- Garnish and enjoy:
- Cut wedges of lime and small spears of watermelon to balance on the rim Add your garnishes and sip immediately while ice cold

There is nothing quite like juicy watermelon in a summer drink The color always reminds me of my childhood trips to the park where we would sit under a tree and eat slices straight off the rind Hands down watermelon is what makes this drink a keeper in our house
Storage tips
The base for this drink can be made up to eight hours ahead and kept in the fridge Just muddle and strain then chill in a covered jar Only salt your glasses and add ice right before serving to keep everything crisp and fresh
Ingredient substitutions
If agave is not available you can swap in honey or a simple syrup Taste and adjust the amount as honey is richer and varies by brand For the salt rim some people like Tajin or a mix of salt and chili powder for a little kick
Serving suggestions
This mocktail is perfect on its own but it also pairs beautifully with tacos or simple grilled veggies For gatherings you can double the recipe and serve in a big pitcher with wheels of lime and slices of watermelon floating on top
