A Blue Lagoon is the kind of drink that makes people stop mid-conversation—mostly because of that electric, pool-blue color. It’s bright and citrusy from the lemonade, lightly sweet from the blue curaçao syrup, and finished with a fizzy lift that keeps it from tasting heavy.
What I love most is how fast it comes together: stir, ice, top with bubbles, and you’re done. If you want a quick refresher that looks special in the glass, this one delivers (and if you’re curious about who’s behind Citrus and Crave, you can peek at my about page anytime).
Why You’ll Love This Recipe
- That unmistakable color payoff: when you stir the lemonade and blue curaçao syrup until fully even, you get a vivid, uniform blue—no streaks.
- Sweet-tart balance: lemonade brings the zing; the blue curaçao syrup rounds it out with a candy-citrus sweetness.
- Bubbly, not flat: the fizzy soda goes in last, so the drink stays lively instead of losing its sparkle.
- Built right in the glass: no shaker, no blender—just a serving glass and a spoon.
- Instant “finished” look: a few lemon slices on top make it look intentional and fresh in seconds.
The Story Behind This Recipe
This is my go-to when I want a drink that feels playful but still clean-tasting: lemonade keeps it crisp, and the blue curaçao syrup gives you that classic Blue Lagoon vibe without any complicated steps—just stir until the color turns perfectly even, then float in the fizz.
What It Tastes Like
Think bright lemonade up front—tangy and refreshing—followed by a sweeter citrus note from the blue curaçao syrup. The fizzy soda adds a gentle sparkle that makes each sip feel lighter, and the lemon garnish hits your nose first with fresh citrus aroma before you even taste it.
Ingredients You’ll Need
This recipe is all about layering: lemonade for tartness, blue curaçao syrup for color and sweetness, and fizzy soda for lift. Use plenty of ice so the soda stays snappy, and finish with lemon slices for a clean, citrusy garnish (and a cue to your brain that this is going to be refreshing).

How to Make Blue Lagoon
- Build the base. Pour the lemonade into a serving glass, then add the blue curaçao syrup. Stir for about 10–15 seconds, until the color is completely uniform—look for a smooth, even blue with no darker swirls at the bottom.
- Ice it down. Fill the glass generously with ice. The goal is a very cold drink; the ice also helps keep the soda from going flat too quickly.
- Top with fizz. Pour in the fizzy soda and give it a gentle stir—just 1–2 slow turns. You want everything combined, but you don’t want to knock out the bubbles.
- Garnish and serve right away. Tuck in a few lemon slices and bring it to the table immediately while it’s extra cold and sparkling. (If you like reading the fine print, here’s our disclaimer.)
Tips for Best Results
- Stir the lemonade + syrup before adding ice. It’s easier to get that perfectly even blue color when you’re not stirring around a glass full of cubes.
- Use lots of ice, not a little. A few cubes melt fast and water the drink down; a fuller glass stays colder longer.
- Add the fizzy soda last. This keeps the carbonation lively—especially important because the drink is stirred more than once.
- Stir gently after the soda goes in. Over-stirring is the quickest way to lose the sparkle.
- Garnish at the end. Lemon slices look brightest (and smell freshest) when they’re added right before serving.
Variations and Substitutions
- Adjust the color and sweetness: add a little more or less blue curaçao syrup to get your preferred shade of blue and sweetness level.
- Dial the bubbles up or down: use more fizzy soda for a lighter, spritzier drink, or less for a more lemonade-forward sip.
How to Serve It
Serve it straight from the glass while the soda is still actively fizzing and the ice is crackly-cold. I like lemon slices tucked against the inside of the glass so you get that bright citrus aroma with every sip. If you’re serving more than one, line them up and garnish last so each drink hits the table bubbly and vivid. (For site info, you can also check the terms and conditions.)
How to Store It
This one is best made and served immediately—once the fizzy soda is added, the bubbles fade and the ice starts to dilute the lemonade. If you want to get ahead, you can mix the lemonade and blue curaçao syrup in the glass first, then hold off on the ice, fizzy soda, and lemon slices until the moment you’re ready to drink.
