Deep dreamy blue, sweet and citrusy, with that tropical pineapple base — ready in under 5 minutes and guaranteed to stop everyone at the table. Completely alcohol-free and kid-friendly.
Okay, so you know those drinks that just look like vacation? That’s exactly what this is. Every single time I make this Blue Lagoon mocktail, someone at the table stops and goes “wait — what is that?” And honestly, that reaction never gets old.
I started making this a couple of summers ago when we had family over and needed something that felt fancy but didn’t take forever. One pitcher, a handful of ingredients, and suddenly the whole backyard has a tropical Caribbean vibe. It’s that kind of drink.
The color alone is half the magic. That deep, dreamy blue from the blue curacao syrup — vibrant, beautiful, and it photographs like an absolute dream. Think mermaid cocktail meets Blue Lagoon lemonade, but completely alcohol-free. My kids go crazy for it, and honestly? So do the adults.

Step-by-Step Instructions
-
1Fill your glass with ice. Don’t skip this. A good amount of ice keeps everything cold and makes the layering look gorgeous.💡 Chill your glass first — pop it in the freezer for 10 minutes before serving. Makes everything feel extra refreshing.
-
2Pour in the lemonade. Add about ½ cup of lemonade over the ice first. This is your base layer.💡 Fresh lemonade makes a real difference — if you have a few extra minutes, squeeze your own. The tartness balances the sweetness so well.
-
3Add the pineapple juice. Pour slowly over the lemonade. It mixes slightly, and that’s fine — you want that tropical base to blend a little.
-
4Add the blue curacao syrup. This is the moment. Pour the blue curacao syrup slowly over the back of a spoon so it sinks to the bottom and you get that gorgeous layered effect. Watch it swirl. It’s so satisfying.💡 The pour-over-spoon trick is the secret to that iconic two-tone blue look. Go slow and resist the urge to stir — let it settle naturally.
-
5Top with sparkling water or soda. Pour gently to keep the layers as long as possible. The bubbles carry everything upward in the most beautiful way.💡 If making a pitcher, hold off on adding the sparkling water until you’re ready to serve — the bubbles fade quickly.
-
6Garnish and serve immediately. Add a lemon slice on the rim, a cherry on top, and a paper straw if you have one. Serve right away — this one’s best fresh.
Cool Blue Lagoon Mocktail — The Non-Alcoholic Blue Hawaiian Drink You’ll Make All Summer
🧄 Ingredients
- 2 ¾ fl_oz Blue curacao syrup (non-alcoholic)
- 1 ¾ cup Lemonade
- 0.5 cup Pineapple juice
- 0.5 cup Sparkling water or lemon-lime soda
- 2 ¾ cup Ice
- 2 ¾ Lemon slices
- 2 ¾ Maraschino cherries
📋 Instructions
-
1
Fill two tall glasses generously with ice. The more ice, the better the layering effect and the colder the drink.
💡 Chill your glass in the freezer for 10 minutes before serving for an extra refreshing result. -
2
Pour 1/2 cup of lemonade into each glass over the ice. This creates the tart, citrusy base layer.
💡 Fresh-squeezed lemonade balances the sweetness of the syrup much better than bottled. -
3
Add 1/4 cup of pineapple juice to each glass. Pour slowly so it blends lightly with the lemonade.
💡 You want a slight blend here — it builds the tropical flavor base. -
4
Hold a spoon just above the surface of the drink and pour 1 oz of blue curacao syrup slowly over the back of the spoon into each glass. This causes the syrup to sink gently and create a beautiful two-tone layered effect.
💡 Pour as slowly as possible for the most defined blue layer. -
5
Top each glass gently with 1/4 cup of sparkling water or lemon-lime soda. Pour slowly to preserve the layers.
💡 The bubbles will naturally lift the blue layer slightly — that swirl is the magic of this drink. -
6
Garnish with a lemon slice on the rim and a maraschino cherry on top. Add a paper straw and serve immediately.
💡 Serve right away for the best carbonation and color effect.

💡 Pro Tips
- Chill your glass first — pop it in the freezer for 10 minutes before serving. Makes everything feel extra refreshing and keeps the drink colder longer.
- Layer slowly — the pour-over-spoon trick is the secret to that iconic two-tone blue look. Patience here pays off visually.
- Use blue curacao syrup, not liqueur — this keeps it fully non-alcoholic and family-friendly. Check the label says “syrup” not “liqueur.”
- Fresh lemonade makes a real difference — if you have a few extra minutes, squeeze your own. The tartness balances the sweetness beautifully.
- Make a pitcher — multiply everything by 6 and hold off on adding the sparkling water until you’re ready to serve, otherwise the bubbles fade.
- Add blue food coloring sparingly if your syrup isn’t vibrant enough — a drop or two goes a long way and deepens the color significantly.
Variations to Try
Add a splash of coconut cream on top and swap the lemonade for passion fruit juice. Garnish with a pineapple slice. Full resort mode — no passport required.
Top with a small scoop of vanilla or coconut ice cream instead of sparkling water. Creamy, cold, and so dreamy — kids absolutely love this version.
Use coconut or berry-flavored sparkling water and add a rim of blue sugar. Looks incredible on a buffet table and makes every guest feel like they’re at a proper party.
Blend everything with 2 cups of ice for a slushy version. Great for hot days when you just need something seriously cold — and incredibly easy to make in batches.
