Frozen Watermelon Margarita
Frozen watermelon margarita — fresh watermelon, tequila, lime. The most refreshing summer cocktail. Ready in 5 minutes. Get the recipe.
A frozen watermelon margarita is the most refreshing drink of summer. Fresh watermelon gets blended with tequila, lime juice, triple sec, and just enough ice to make it slushy. It’s naturally sweet, barely needs added sugar, and it’s the drink that makes a hot afternoon bearable. Make a batch for your next cookout.
Why You’ll Love This Frozen Watermelon Margarita
Why this is the summer drink:
- Naturally sweet — ripe watermelon means little to no added sugar.
- 5 minutes, one blender — no cocktail shaker required.
- Scales easily — double or triple for a crowd.
- Customizable — add jalapeño for heat, swap tequila for mezcal for smoke.
Ingredients
For 4 servings:
- 4 cups seedless watermelon, cubed and frozen
- 6 oz tequila blanco
- 3 oz triple sec or Cointreau
- 3 oz fresh lime juice (about 3 limes)
- 1-2 tbsp agave nectar (optional)
- 2 cups ice
- Kosher salt for rimming
- Lime wedges and watermelon slices for garnish
Freeze the watermelon first
Cube the watermelon and freeze on a sheet pan for at least 2 hours. This gives you a thick, slushy texture without too much ice.
Equipment You’ll Need
- Blender (high-speed)
- Citrus juicer
- Measuring jigger
- Rimmed glasses (4)
How to Make Frozen Watermelon Margarita
Step 1 — Rim the glasses (2 minutes)
Run a lime wedge around the rim of 4 glasses. Dip each rim in kosher salt. Set aside.
Step 2 — Blend (2 minutes)
Add frozen watermelon, tequila, triple sec, lime juice, and ice to a high-speed blender. Blend on high until smooth and slushy — about 30 seconds. Taste. If not sweet enough, add agave 1 tbsp at a time.
Step 3 — Pour and serve (1 minute)
Pour into rimmed glasses. Garnish with a watermelon wedge and lime wheel. Serve immediately.
Pro Tips for Best Results
High-speed blender matters. A regular blender can struggle with frozen fruit. Let watermelon thaw 5 minutes if needed.
Taste before adding sweetener. A ripe watermelon is sweet enough on its own.
Make it a mocktail. Skip the tequila and triple sec. Add 2 oz sparkling water per serving.
Variations & Substitutions
Spicy watermelon margarita
Add 1 sliced jalapeño (seeds removed) to the blender.
Mezcal watermelon margarita
Swap tequila for mezcal. The smoky flavor with watermelon is incredible.
Pitcher version
Multiply everything by 3 for 12 servings. Blend in batches and combine in a pitcher.
Storage, Make-Ahead & Reheating
Drink immediately. Frozen margaritas don’t store well.
Make-ahead base: Mix tequila, triple sec, lime juice, and agave in a pitcher. Refrigerate up to 3 days. Blend with frozen watermelon when ready.
What to Serve With Frozen Watermelon Margarita
Frozen watermelon margaritas are the perfect partner for anything off the grill — tacos, burgers, grilled shrimp, or chips and guacamole.

Frequently Asked Questions
Can I use fresh (unfrozen) watermelon?
Yes, but add more ice — about 3 cups total. The texture will be slightly thinner.
How do I make this for a crowd?
Triple the recipe and blend in batches. Combine in a large pitcher.
Can I use bottled lime juice?
Fresh is dramatically better. Bottled lime juice has a metallic taste in simple drinks.
