Easy Sonic Ocean Water Copycat Recipe You Can Make At Home

Easy Sonic Ocean Water® Copycat Recipe (So Refreshing!)

If you’ve ever pulled into Sonic on a hot day, there’s a good chance you’ve ordered their bright blue, coconut-kissed Ocean Water®. It’s icy, sweet, and just a little bit tropical—kind of like a mini beach vacation in a styrofoam cup. In this post, I’ll show you how to make a super simple Sonic Ocean Water® copycat recipe at home using just a few ingredients you can find at almost any grocery store. No fancy tools, no complicated steps—just a fun, family-friendly drink you can whip up in minutes.

A Quick Note About Sonic Drive-In & Ocean Water®

Sonic Drive-In is a classic American drive-in restaurant known for its roller-skating carhops (in some locations), huge drink menu, and comfort food. If you grew up in the USA, there’s a good chance Sonic is part of your summer memories—windows rolled down, ice clinking in the cup, and sweet drinks in every color of the rainbow. Ocean Water® is one of Sonic’s most iconic drinks. It’s:
  • Bright blue and eye-catching
  • Sweet but with a light, clean taste
  • Coconut-flavored with a gentle tropical vibe
  • Cold and fizzy thanks to lemon-lime soda
When you take a sip, you get that crisp fizz on your tongue, a wave of coconut sweetness, and just enough citrus to keep it from being heavy. It feels like summer in a cup. Important: Ocean Water® is a trademarked drink owned by Sonic Corp. This recipe is a homemade copycat version inspired by the original. It is not the official Sonic recipe, and we are not affiliated with Sonic Drive-In.

Homemade Sonic Ocean Water® Copycat Recipe

This version keeps things easy and uses common ingredients. You don’t need any special syrups—just a few pantry staples and some ice.

Serving Size & Yield

  • Yield: About 4 servings
  • Serving Size: 1 (about 12-ounce) glass

Ingredients

*Note: Cream of coconut (like Coco López) makes the drink slightly cloudy and a little richer. Coconut syrup (often used for coffee drinks) keeps it clear and closer to what you get at Sonic. Both work—just slightly different looks and textures.

Step-by-Step Instructions

Prep Time & Total Time

  • Prep Time: 5–10 minutes
  • Total Time: 5–10 minutes

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.
If you’ve got kids around, this is a fun “helping hands” recipe—they can stir in the food coloring and help taste-test the sweetness.

Approximate Nutrition (Per 12 oz Serving)

These numbers are estimates and will change based on the brands you use.
  • Calories: ~150–180
  • Carbohydrates: ~40–45 g
  • Sugars: ~40–45 g
  • Fat: 0–2 g (slightly higher if using cream of coconut)
  • Protein: 0 g
  • Sodium: ~30–60 mg
This drink is definitely a treat, not an everyday beverage—but that’s part of what makes it fun.

Super-Simple Version (Pantry & Dollar-Store Friendly)

Need an even easier route? Maybe for a party, pool day, or when you don’t want to fuss? Try this stripped-down version:
  • 4 cups lemon-lime soda
  • 2–3 teaspoons coconut extract
  • 2–4 tablespoons sugar (or to taste)
  • A few drops blue food coloring
  • Ice
Steps:
  • Stir the sugar and coconut extract into a small amount of soda until dissolved.
  • Pour into a pitcher, add the rest of the soda, then stir in the blue food coloring.
  • Serve over ice.
Coconut extract is very strong, so start small. Taste and adjust. This version is perfect if your grocery store doesn’t carry coconut syrup.

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: Again, it’s more of an “ocean-inspired” drink than a strict copy, but it works if you’re avoiding soda and artificial colors.

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.

Why This Sonic Ocean Water® Copycat Works

This recipe focuses on three things Sonic fans love:
  • Color: That bright blue “ocean” look that makes you smile before you even taste it.
  • Flavor: Simple combo of lemon-lime soda plus coconut—sweet, crisp, and tropical.
  • Texture: Ice-cold and bubbly, especially with crushed ice.
You don’t need bar tools or restaurant equipment—just a pitcher, a spoon, and some ice. It’s an easy way to bring a little Sonic fun home for movie nights, birthdays, or just because.
