The Best Blue Lagoon Mocktail (With a Healthy Version)

This beautiful blue mocktail is non alcoholic and tastes just as good as it looks. With a healthy and classic version, you can enjoy this virgin blue lagoon in any way you please.

I’ve had so many requests for a blue lagoon mocktail over the last 18 months but I never quite knew how to approach this drink. A traditional Blue Lagoon has blue curaçao, lemonade and vodka – so essentially full of sugar and booze. It doesn’t really fit with my motto of ‘drink yourself healthy’.

So I went on the hunt for other ways to recreate this classic and ended up with a healthy-ish version and a not so healthy version. Both are just as simple as the original, and just as delicious too!

Note: the mocktail in this post is the healthy version made with blue spirulina. If you use the blue curacao syrup, the tint of blue will be slightly different.

What Does a Blue Lagoon Mocktail Taste Like?

When it’s made properly, this classic drink will taste refreshing and sweet. With it’s delicious flavor and striking colour, it’s like capturing summer in a glass.

If you’re a sweet tooth, you’ll love the original (aka ‘not-so-healthy’) version of the recipe. To be honest, it’s a touch too sweet for me, I much prefer healthy, low sugar mocktails.

The healthier version is still sweet (it’s made with sugar-free lemonade), but not as sweet as the original. Blue spirulina gives the drink it’s incredible colour, making it a perfect blue mocktail recipe for baby showers. Always consult your doctor before taking spirulina while pregnant.

How to make it

The classic version

A classic blue lagoon is made with blue curacao syrup, lemonade and vodka. It’s usually served in a tall glass with a tropical fruit garnish.


  • 1 tablespoon blue curaçao syrup
  • 1oz/30mls of your favorite alcohol-free spirit, preferably non alcoholic vodka (optional)


Pour the blue curaçao syrup and the alcohol-free spirit of your choice (if you’re using it) into your glass and slowly top with lemonade. Stir gently, add ice, garnish, and serve.

The healthy version

Healthy blue spirulina creates that iconic blue color in this recipe. With low sugar lemonade and your choice of alcohol free spirit, this easy mocktail can be whipped up in minutes.


  • 1/2 teaspoon blue spirulina : I buy mine from health food shops and it can also be purchased online.
  • 1 cup sugar free/low sugar lemonade
  • 1 shot of your favorite alcohol-free spirit (optional)

If you don’t like the idea of ​​using lemonade, any pale liquid will work. Think tonic water, pale kombucha, etc.

Place the blue spirulina in your glass then add the lemonade. Stir gently. You might find the drink foams up a bit as the 2 ingredients react with each other, so just scoop the foam out – although my boys thought this was ‘supercool’ and wanted to eat it instead!

Add your favorite alcohol-free spirit if using and stir again.

Add ice, garnish, and serve.

Frequently asked questions

Is blue curaçao syrup alcoholic?

I am regularly asked – does blue curacao have alcohol? While the liqueur blue curaçao is alcoholic, most blue curaçao syrups are non-alcoholic. They add the color and flavor of the liqueur without any alcohol. Be sure you check the label on the brand you choose though just in case.

What type of glass should I serve a Blue Lagoon Mocktail in?

The traditional glass for this classic cocktail is the hurricane glass. This is sometimes referred to as a tulip glass. If you don’t have a tulip glass, try a highball glass instead.

What garnish should I use?

There are many ways to garnish your virgin Blue Lagoon, the sky really is the limit. Lemon or orange slices are always an excellent choice. You can serve it with either of those plus a couple maraschino cherries thrown in for good measure.
For something more floral and fancy, orchid blossoms will look incredible and add that WOW-factor. But if that’s too much for you, mint sprigs will add that herbal, bespoke touch.

I hope you enjoy your blue lagoon mocktail as much as I enjoyed creating it!
