About This Recipe
A frozen mojito slushy is the perfect shortcut to summer refreshment — bright lime, cooling mint and clear white rum transformed into a spoonable, slightly granular slush that sits somewhere between a daiquiri and a granita. This version leans on technique rather than tricks: the mint is gently bruised in simple syrup to coax out aromatic oil without the harshness bruised or shredded leaves can bring, the lime is kept fresh and assertive to cut through the sweetness, and the Ninja Slushie program is used with short pulses so you get a velvety, icy texture rather than a watered-down smoothie. The optional splash of club soda at the end wakes the flavors and adds a light fizz that keeps the drink lively as you sip.
This recipe is designed for hosts who want consistency and speed — it produces a slush that pours cleanly into glasses and holds up just long enough for cocktails and conversation. It’s also forgiving: taste before you blend because alcohol and ice mute flavors, and adjust the syrup or lime as needed. If you like deeper notes, swap in a slightly aged rum or add a hint of coconut or tropical fruit during blending; if you prefer a lighter drink, reduce the rum and top more generously with sparkling water.
Ingredients for Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine
- 1 cup (loosely packed) Fresh mint leaves (loosely packed)
- 1/3 cup Simple syrup (1:1 sugar to water)
- 1/2 cup Fresh lime juice
- 1 cup White rum
- 6 cups Ice (large cubes)
- 1 cup Club soda or sparkling water (optional, to top)
- 4 wheels Lime wheels (for garnish)
How to Make Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine
Step 1: Bruise the mint with simple syrup
Place the mint leaves and simple syrup in a sturdy bowl or the base of the Ninja pitcher. Gently muddle (10–12 firm presses) with a muddler or the back of a wooden spoon to release the mint oils without shredding the leaves; alternatively, pulse the mint and syrup 2–3 short bursts in the Ninja to bruise the leaves.For this step
- 1 cup (loosely packed)Fresh mint leaves (loosely packed)
- 1/3 cupSimple syrup (1:1 sugar to water)
Step 2: Add lime juice and rum
Pour the fresh lime juice and white rum into the muddled mint mixture and stir to combine. Taste and adjust sweetness with a little more simple syrup if needed (keep in mind blending and ice will mute flavors slightly).For this step
- 1/2 cupFresh lime juice
- 1 cupWhite rum
Step 3: Build and blend the slushy in the Ninja
Add ice to the Ninja Slushie pitcher up to the max fill line, then pour the mint-rum-lime mixture over the ice. Use the Ninja's ice/crush setting with short pulses: start with 3–4 quick pulses, then run the Slush or Smoothie program for 30–45 seconds. Stop, check texture, and pulse in 5–10 second bursts until you have a smooth, velvety slush — avoid over-blending which warms the ice.For this step
- 6 cupsIce (large cubes)
Step 4: Finish and top with soda
Spoon the slushy into chilled glasses, leaving room at the top. Add a splash (about 1–2 tbsp) of club soda to each glass to brighten the flavor and give a light effervescence, then gently stir just once to combine.For this step
- 1 cupClub soda or sparkling water (optional, to top)
Step 5: Garnish and serve immediately
Garnish each glass with a lime wheel and a small sprig of fresh mint. Serve immediately with a straw — the slush is at its best right away; if it sits, give a quick 3–5 second re-pulse in the Ninja to revive texture.For this step

Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine Tips
Bruise, don’t shred
Press mint 10–12 times with a muddler or two to three short machine pulses—this releases aromatic oils without releasing bitter chlorophyll from torn leaves.
Use large ice cubes
Big cubes crush into a creamier slush and warm more slowly than crushed ice; fill the Ninja to the max line with large cubes for best texture.
Pulse, then program
Start with 3–4 short pulses to break ice, then run the Slush or Smoothie program in 30–45 second increments, checking frequently to avoid warming.
Adjust before blending
Taste the mint-syrup-lime-rum mix first—add more simple syrup if too tart or a splash more lime if too sweet, since blending will mute flavors.
Revive with a quick pulse
If the slush sits and separates, give it a 3–5 second re-pulse in the Ninja or let it soften 2–3 minutes, then stir; avoid heavy re-blending that melts it.
Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine Variations and Substitutions
Virgin Mojito Slushy
Omit the rum and replace with 1 cup chilled club soda plus 1/4 cup white grape or apple juice for body, then blend as directed and top with extra soda for fizz.
Coconut-Pineapple Twist
Use 3/4 cup white rum and 1/4 cup coconut rum, add 1/2 cup pineapple juice and reduce ice by 1 cup for a tropical, pina-colada-like slush.
Berry-Mint Mojito
Add 1 cup frozen strawberries or raspberries and reduce ice by 1 cup; the fruit adds sweetness and color—use a touch less syrup to keep balance.
Herb-Forward Variation
Substitute half the mint with fresh basil for a savory, aromatic slush that pairs beautifully with grilled seafood.
How to Store and Make Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine Ahead
This slushy is best served immediately; if you must store it, pour the blended slush into an airtight container and freeze for up to 48 hours—it will harden and need a quick 3–5 second re-pulse or 5–10 minute thaw before serving. You can prepare the mint-simple syrup-lime-rum mixture up to 24 hours ahead and refrigerate; keep simple syrup on hand for up to a month in the fridge.
What to Serve With Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine
Serve in chilled highball or coupe glasses with a short straw and lime wheel garnish; a light sugar rim is optional but avoid heavy garnishes that melt into the slush. Pair with bright, summery dishes like ceviche, grilled fish tacos, citrus salads, or salty snacks such as plantain chips and fried shrimp skewers to complement the drink’s acidity and minty freshness.
Frozen Mojito Slushy with Fresh Mint for the Ninja Slushie Machine FAQs
Can I make this in a regular blender instead of a Ninja?
Yes—use a high-powered blender with an ice-crush setting, work in 30–45 second bursts and pause to check texture, and avoid running continuously to prevent warming the mixture; you may need to blend in batches.
How do I prevent the mint from tasting bitter?
Avoid tearing the leaves; bruise gently with syrup or in 2–3 short machine pulses, remove any tough stems, and don’t over-steep mint in hot liquid—bitterness comes from crushed stems and over-oxidation.
How strong is each serving and can I make it lighter?
This recipe uses 1 cup (8 oz) rum for four servings—about 2 oz per glass; to make it lighter, reduce rum to 3/4 or 1/2 cup, increase club soda, or add a splash more lime and water to keep volume and balance.
Can I prep anything ahead of time?
Yes—the mint muddled into simple syrup with the lime and rum can be mixed and refrigerated up to 24 hours ahead; blend with ice just before serving for best texture.
What if my slush turns out grainy or watery?
Graininess usually means over-crushed ice or melting—pulse in short bursts and stop when velvety; watery slush means too much melting, so work quickly, use large cubes, and keep the Ninja chilled between batches.
