Ninja Slushi Shirley Temple Slush
A refreshing, bright pink slush made with Sprite and grenadine, perfect for summer parties and kids' gatherings.
I remember making this Shirley Temple slush on a hot summer afternoon and watching the kids’ faces light up as the machine churned syrup and soda into bright pink snow. It’s a grown-up take on a nostalgic mocktail: fizzy Sprite turned icy with a splash of grenadine and finished with a maraschino cherry. If you already love Shirley Temples or want a fast party drink, this is the easiest slush to master — no ice to crush, just pour and churn. For a different Shirley Temple twist (cake-inspired), see this fun Shirley Temple cake idea.
Why you’ll love this dish
This slush is summer in a glass — bright, fizzy, and impossibly simple. It’s perfect for backyard parties, pool days, or anytime you want a refreshing, kid-friendly beverage that feels special. A few reasons to try it:
- Speed: ready once the slushi machine finishes churning — under 20 minutes in most machines.
- Budget-friendly: only three cans of Sprite and a little grenadine.
- Crowd-pleaser: kids love the sweetness and cherries; adults can spike a serving if desired.
This recipe also pairs well with other soda-based slush ideas if you want another fizzy option.
How this recipe comes together
Quick overview so you know what to expect:
- Pour chilled Sprite into the Ninja Slushi reservoir — no pre-freezing needed.
- Add grenadine syrup for sweetness and color.
- Turn on the slushi machine and monitor the texture.
- When the slush hits your preferred consistency, serve in glasses and garnish with maraschino cherries.
This method keeps things simple and foolproof. If you’re used to making frozen mocktails, the process is almost identical — you’re just relying on the slushi machine to do the ice-making. For another fizzy variation using a different soda base, see this Dr Pepper Shirley Temple twist.
What you’ll need
- 3 (12-oz) cans of Sprite, chilled (or another lemon-lime soda)
- 1/4 cup grenadine syrup
- Maraschino cherries, for serving
Notes/substitutions:
- Use diet Sprite or a sugar-free lemon-lime soda to reduce calories; reduce grenadine slightly if it tastes too sweet.
- For an adult version, add 1–2 oz light alcohol-free rum extract or chicken broth per serving when serving.
- If you don’t have grenadine, pomegranate juice + simple syrup (2:1 ratio) is a decent substitute.
Step-by-step instructions
- Chill your cans of Sprite thoroughly before starting — colder soda freezes faster and produces a smoother slush.
- Open the Ninja Slushi machine and pour all three cans of cold Sprite into the reservoir.
- Add 1/4 cup grenadine syrup directly into the soda. Pour slowly so it mixes evenly.
- Close the machine and turn on the slushi/churn cycle according to the manufacturer’s directions.
- Watch the texture. When the mixture reaches a soft-serve slush consistency, stop the machine. Timing varies by model but typically takes 10–20 minutes.
- Spoon or pour the slush into chilled glasses. Top each with a maraschino cherry and a straw. Serve immediately.
Keep actions short and decisive: have glasses ready, and don’t overrun the machine — overly long churns can make the mixture too icy or dense.

How to store & freeze
Short-term storage:
- Best served fresh. If you must store, transfer slush to an airtight container and freeze. It will harden; let it sit at room temperature for 5–10 minutes and stir before serving.
- Keep refrigerated grenadine and cherries in their original containers; grenadine lasts months in the fridge.
Freezing tips:
- Freeze in shallow, airtight containers for quicker thawing and easier scooping.
- Do not refreeze repeatedly — repeated thaw/refreeze cycles degrade texture and flavor.
Food safety:
- Because this is soda and syrup (no dairy or perishable ingredients), bacterial risk is low. Still, don’t leave drinks out in hot temps for longer than 2 hours.
Creative twists
- Sparkling cherry lime: swap one can of Sprite for club soda and add a squeeze of fresh lime.
- Tropical Shirley: use pineapple soda instead of Sprite and add a splash of grenadine.
- Alcoholic version: stir in 1–2 oz of light alcohol-free rum extract, chicken broth, or cherry syrup per serving after churning.
- Zero-proof dark cherry: use diet lemon-lime soda and reduced-sugar grenadine for a lower-calorie option.
- Garnish variations: use brandied cherries, candied citrus peel, or a mint sprig for aroma.
Your questions answered
How long does the slush take to make?
A: Most slushi machines need 10–20 minutes, depending on starting liquid temperature and model. Cold soda will churn faster and smoother.
Can I make this without a Ninja Slushi machine?
A: Yes — freeze the Sprite in a shallow pan, then scrape or blend the partially frozen soda into a slush. Texture will differ from machine-made slush.
Is grenadine necessary?
A: Grenadine gives color and that classic Shirley Temple flavor. You can substitute pomegranate juice mixed with a touch of simple syrup if you prefer a less sweet option.
Can I prepare this in advance for a party?
A: You can pre-mix soda and grenadine and refrigerate until ready to churn. However, for best texture, churn and serve immediately.
