Blueberry Lemon Slush Mocktail Recipe

Honestly, I keep coming back to this recipe because it doesn’t require anything fancy. Some ice, fresh or frozen fruit, and a splash of sparkling water, and you’re set.

Equipment

• Blender (for crushing and blending)
• Measuring cups and spoons
• Cocktail shaker (optional, if you’re feeling fancy)
• Fine mesh strainer (if you want it super smooth)
• Tall glasses for serving
• Straws
• Spoon for stirring
• Citrus juicer for squeezing lemons

I always double-check that everything’s clean before I start—especially the blender. Makes things easier if you lay it all out on the counter first.

Ingredients

• 1 cup frozen blueberries
• ½ cup fresh blueberries (for garnish and a bit of texture)
• ¾ cup fresh lemon juice (usually 3-4 lemons)
• ½ cup simple syrup (or swap for agave nectar if that’s your thing)
• 1 cup ice cubes
• 1 cup sparkling water, seltzer, or club soda
• Extra mint leaves for garnish
• 1 tablespoon granulated sugar (optional, for the rim or if you want it sweeter)

Fresh lemon juice is always my pick—it just tastes brighter. I like frozen blueberries for that extra chill, but fresh ones work if that’s what you’ve got. Simple syrup blends in smoothly and gives just enough sweetness.

Instructions

• Toss the frozen blueberries, ice cubes, lemon juice, and simple syrup into the blender.
• Blend until it’s all slushy—don’t overthink it.
• Give it a taste and add more sugar or syrup if it needs a little more sweetness.
• If you prefer it smoother, strain the mixture through a fine mesh strainer.
• Pour the slush halfway up your glasses.
• Top with sparkling water, seltzer, or club soda—whatever’s on hand.
• Stir gently so the bubbles do their thing.
• Drop in a few fresh blueberries and some mint leaves for garnish.
• If you’re feeling extra, wet the rims with lemon juice and dip them in sugar.

Sometimes I’ll chill the glasses in the freezer first. It keeps the slush colder, longer—worth the extra step if you ask me.

Notes

I always go for ripe lemons and juicy blueberries if I can find them. Every now and then, I’ll toss in a few strawberries or raspberries—just depends on what’s in the fridge.

If I want it sweeter, I’ll use more syrup; if not, I dial it back. Agave’s a nice switch if you’re avoiding regular sugar, but simple syrup is classic.

More bubbles? Just add extra sparkling water. Less sweet? Cut back on the syrup. I try to serve this right away—otherwise, the ice melts and the fizz fades. Mint leaves go in at the end so they stay fresh and pretty, not muddled into the drink.

Tasting Notes

The first sip of this Blueberry Lemon Slush Mocktail? Oh, the burst of fresh lemon hits right away. That bright, citrusy zing wakes up my taste buds and honestly, it’s so refreshing.

Then the blueberry starts to show up. Sweet, but not in an overwhelming way. There’s this gentle, fruity finish from the berries that really balances out the tart lemon.

The texture—well, it’s got that smooth, icy thing going on. Thick enough to be satisfying, but still light and super cooling, especially when it’s hot outside.

Every sip just feels energizing and crisp. Sometimes, if I toss in a little mint or a few extra berries, there’s this subtle twist that makes it even better. I never find it too sweet or too sour—it lands right in that happy middle, which I really appreciate.
