This blueberry sriracha margarita brings an unexpected twist to a classic cocktail. The sweet blueberries balance perfectly with spicy sriracha and tangy lime, creating a vibrant purple drink that surprises with every sip. After experimenting with dozens of margarita variations, this combination quickly became my signature cocktail for summer gatherings.
I first created this recipe when friends dropped by unexpectedly on a hot summer evening. With just blueberries, limeade and a splash of sriracha in my fridge, this happy accident became the most requested cocktail at every gathering I host.
Ingredients
- Fresh blueberries: Provides natural sweetness and that gorgeous purple hue
- Limeade concentrate: Delivers that classic margarita tang without squeezing multiple limes
- Sriracha sauce: Adds unexpected heat that complements the sweetness perfectly
- Tequila: Choose a silver or blanco tequila for the cleanest flavor profile
- Ice: Essential for proper dilution and temperature
- Salt for rim: Creates that classic margarita experience and balances sweetness
- Blueberries for garnish: Adds visual appeal and a hint to what's inside
Step-by-Step Instructions
- Blend The Base:
- Pour fresh blueberries, limeade and sriracha into a blender. Ensure blueberries are washed thoroughly and pick out any stems. Blend on high speed for about 30 seconds until completely smooth with no visible blueberry skin remaining.
- Add The Alcohol:
- Pour in the tequila after the initial blend. This prevents alcohol from evaporating during the high-speed blending process. Pulse just 2-3 times to incorporate without creating too much foam.
- Prepare The Glass:
- Take a lime wedge and run it around the rim of your glass, then dip into salt. The moisture helps salt adhere better than using water. Fill the glass with ice cubes rather than crushed ice to prevent too-rapid dilution.
- Pour And Garnish:
- Slowly pour the vibrant purple mixture over the ice, allowing it to cascade beautifully down the sides. Thread 2-3 fresh blueberries on a cocktail pick and place across the rim for an elegant finishing touch.

My absolute favorite thing about this margarita is watching guests take their first sip. The expression changes from curiosity to surprise to delight as they taste the unexpected heat following the sweet blueberry flavor. My brother-in-law, who claims to hate fruity drinks, asked for seconds and then requested the recipe.
Spice Customization
The beauty of this margarita lies in its adaptability to different heat preferences. For those who enjoy a mild tingle, the recipe's ½ teaspoon provides just enough warmth without overwhelming the fruit. Heat seekers can gradually increase to 1 or even 1½ teaspoons of sriracha. I recommend starting conservatively and adding more after tasting rather than risking an overly spicy first batch. The capsaicin in sriracha actually enhances the perception of the blueberry flavor through contrast, creating a more complex drinking experience than traditional margaritas.
Make It Alcohol-Free
This vibrant drink makes an excellent mocktail for those avoiding alcohol. Simply omit the tequila and add an extra splash of limeade to maintain the proper consistency. The blend of sweet blueberries and spicy sriracha creates a sophisticated flavor profile that needs no alcohol to impress. I serve this version regularly at summer gatherings where some guests prefer non-alcoholic options. For an extra special touch, add a splash of club soda for effervescence and garnish with a lime wheel alongside the blueberries.
Serving Suggestions
This uniquely colored margarita pairs beautifully with Mexican and Tex-Mex dishes where the spice complements similar flavor profiles. The sweet-spicy combination works particularly well alongside street tacos, grilled corn with cotija cheese, or classic guacamole. For a complete themed experience, serve these margaritas with a platter of chile-lime shrimp or chicken tinga tostadas. The cooling effect of the iced drink perfectly balances spicy food while the sriracha element creates a harmonious flavor bridge between beverage and meal.

Frozen Variation
Transform this margarita into a slushy frozen treat perfect for scorching summer days. Simply freeze the blueberries beforehand, then blend them with half the amount of ice called for in the original recipe. The resulting texture becomes thick and spoonable rather than sippable. You might need to add a touch more limeade to achieve proper blending. This version pairs wonderfully with dessert courses or as a refreshing afternoon treat by the pool. The frozen version intensifies the blueberry flavor while somewhat tempering the sriracha heat.
