✔ Updated · fixed the card (real amounts for 1 drink), added a pitcher batch and kid-friendly tips
My Blue Lagoon mocktail is the famous electric-blue lemonade drink with zero alcohol: blue curaçao syrup, fresh lemon and sparkling lemonade over ice. It takes 5 minutes, and kids go wild for the color.
At a glance
The one tip that matters: Use non-alcoholic blue curaçao SYRUP, not blue curaçao liqueur. The bottles look alike on the shelf, so check the label for 0% alcohol before you pour.
Why I Love This Blue Lagoon Mocktail
- That color, a bright Caribbean blue that makes any glass look like a vacation.
- Three ingredients, plus ice. No shaker, no blender, no fuss.
- Sweet-tart and fizzy, with fresh lemon cutting through the syrup.
- Easy to batch into a pitcher for parties, showers and kids' birthdays.
What You Need for a Blue Lagoon Mocktail
Exact amounts are in the recipe card below.
- Blue curaçao syrup: the non-alcoholic syrup that brings the orange flavor and that famous blue color.
- Fresh lemon juice: the sour balance. Half a lemon is plenty for one glass.
- Sparkling lemonade or lemon-lime soda: the fizzy body of the drink. Any clear, carbonated lemon soda works.
- Ice: lots of it, so the drink stays cold to the last sip.
- Garnish: a lemon wheel and a cherry. That little pop of red against the blue is my favorite bit.

Tips for Success
- Syrup, not liqueur. Blue curaçao liqueur contains alcohol. For a true mocktail I always grab the non-alcoholic blue curaçao syrup, which sits with the coffee syrups in most stores.
- Fresh lemon is the secret. The syrup is basically orange-flavored sugar, so a squeeze of real lemon is what keeps it from tasting like candy. Bottled lemon juice tastes flat here.
- Pour the fizz last and slowly. Tip the glass and pour the soda down the side, then stir just once or twice. Stir hard and you knock all the bubbles out.
- Less sweet? Swap half the lemonade for plain sparkling water and add an extra splash of lemon. That's how I make mine.
- Make blue ice cubes. Freeze a little lemonade with a few drops of the syrup in an ice tray. As they melt, the drink stays blue instead of watery.

minutesAn alcohol-free Blue Lagoon: non-alcoholic blue curaçao syrup and fresh lemon juice stirred over ice and topped with sparkling lemonade or lemon-lime soda. Bright blue, sweet-tart and ready in 5 minutes.
Ingredients
3/4 oz non-alcoholic blue curaçao syrup
3/4 oz fresh lemon juice (about 1/2 lemon)
5 oz sparkling lemonade or lemon-lime soda, chilled
1 cup ice cubes
1 lemon wheel, for garnish
1 maraschino cherry, for garnish (optional)
Directions
- Chill a hurricane or highball glass (about 12 to 14 oz) in the freezer for 5 to 10 minutes, then fill it about three-quarters full with ice.
- Pour in the blue curaçao syrup and the fresh lemon juice.
- Slowly top with the chilled sparkling lemonade or lemon-lime soda, pouring down the side of the glass so it keeps its fizz.
- Stir gently once or twice with a long spoon, just until the color is an even bright blue. Taste and add a splash more lemon if it is too sweet.
- Garnish with a lemon wheel and a cherry and serve right away, while it is cold and fizzy.
Notes
- You don’t have to use the ingredients in any specific order. However, some people add lemonade and blue Curaçao, give it a mix, and then test the sweetness. This allows them to easily adjust the flavor profile.

Blue Lagoon Mocktail Pitcher for a Party
This is the version I make for birthday parties. For 8 glasses, stir 3/4 cup blue curaçao syrup with 3/4 cup fresh lemon juice in a big pitcher and chill it for up to 4 hours.
Right before serving, pour in 5 cups of cold sparkling lemonade and stir once. Put the ice in each glass, not in the pitcher, so the last glass tastes as good as the first.
Easy Variations
- Blue lime: use fresh lime juice instead of lemon for a sharper, tangier drink.
- Orange twist: add 1 oz orange juice. The drink turns a little greener, but it tastes great.
- Minty: clap a few mint leaves between your hands and drop them in before the soda.
- Frozen Blue Lagoon: blend the syrup, lemon juice and 1 1/2 cups ice until slushy, then top with a splash of lemonade.

Is blue curaçao syrup alcoholic?
No. Blue curaçao syrup is a sugar syrup flavored with bitter orange and colored blue, with no alcohol. Blue curaçao liqueur is the alcoholic version, so check the label says 0% alcohol if you are making this for kids or anyone avoiding alcohol.
Is a Blue Lagoon drink OK for kids?
Yes, this version is alcohol-free, so it is a fun party drink for kids. It is sweet, so you can cut the syrup to 1/2 oz and use half sparkling water for a lighter drink.

Can I make it ahead?
Mix the syrup and lemon juice up to a day ahead and keep it covered in the fridge. Add the ice and fizzy lemonade only when you serve, or the drink will go flat and watery.
