| This easy Sonic Ocean Water copycat recipe is bright blue, fizzy, and lightly coconut-flavored—just like the drive-thru favorite, made at home in minutes |
Since this is a no-cook drink, there’s no cooking temperature to worry about, but keep ingredients chilled and handle everything with clean hands and tools for food safety.
Step 1: Chill Everything
- Place your lemon-lime soda in the fridge until very cold.
- If you’re using glasses instead of plastic cups, you can pop them in the fridge or freezer for 10–15 minutes so they frost up nicely.
Step 2: Mix the Coconut Base
- In a medium pitcher, add the coconut syrup (or cream of coconut).
- If you like your drinks sweeter, stir in the simple syrup or sugar.
- Whisk or stir until the coconut and sweetener are fully combined. If using granulated sugar, make sure it dissolves.
Step 3: Add the Soda
- Slowly pour in the cold lemon-lime soda.
- Gently stir to combine. Go light on stirring—you don’t want to lose all the bubbles.
Step 4: Turn It That Signature Blue
- Add 4–6 drops of blue food coloring to the pitcher.
- Stir gently until the color is even.
- If you want a deeper ocean-blue, add another drop or two. It’s easier to add more than to fix it if it’s too dark.
Step 5: Fill Your Glasses
- Fill each glass about 3/4 full with ice. Crushed ice works best for that authentic Sonic feel.
- Pour the blue soda mixture over the ice, leaving a little room at the top.
Step 6: Garnish & Serve
- Top each glass with a lime wedge or a cherry, if you like.
- Serve immediately while it’s ice-cold and fizzy.

Fun Variations & Party Ideas
Want to dress it up a bit? Here are some easy twists:- “Shark” Ocean Water: Drop in a few gummy sharks for a kid’s ocean-themed party.
- Frozen Slush: Blend the finished drink with ice until slushy. Serve immediately.
- Lower-Sugar Version: Use diet lemon-lime soda and a sugar-free coconut syrup.
- Ocean Punch Bowl: Double or triple the recipe, pour into a big clear bowl, and add floating lemon or lime slices.
Allergy & Dietary Modifications
Even though this drink is pretty simple, here are some common questions and adjustments.Gluten-Free
Most lemon-lime sodas and coconut syrups are naturally gluten-free, but:- Always check the label for “gluten-free” or hidden ingredients you’re unsure about.
- Food coloring is usually gluten-free but confirm if you’re highly sensitive.
Dairy-Free & Vegan
- Dairy-free: Choose coconut syrup or a dairy-free cream of coconut (many are naturally dairy-free, but always check).
- Vegan: Use a lemon-lime soda and coconut syrup that do not contain animal-derived ingredients; some red-dyed garnishes or certain food colorings may not be vegan, so check labels.
Lower Sugar Options
- Use diet or zero-sugar lemon-lime soda.
- Swap regular coconut syrup for a sugar-free coconut flavoring syrup.
- Skip the extra sugar/simple syrup or use a sugar-free sweetener (start with a small amount and taste).
Paleo / “Cleaner” Treat Version
This won’t taste exactly the same, but you can get a similar tropical, refreshing vibe:- Use sparkling water instead of soda.
- Add a little unsweetened coconut water and a drizzle of honey or maple syrup.
- Use a natural blue coloring made from spirulina or butterfly pea flower, if desired.
Storage & Make-Ahead Tips
- Best served fresh: The fizz is strongest right after mixing.
- Short-term storage: You can mix the coconut + sweetener + coloring ahead of time and keep it covered in the fridge for up to 2–3 days. Add the soda just before serving.
- Ice last: Don’t add ice to the pitcher ahead of time or it will water the drink down.
