Rum Slush

This rum slush is a refreshing, icy cocktail that’s perfect for warm days, parties, or anytime I want a fun frozen drink. I love how the sweet, citrusy flavors blend with the smooth kick of rum, creating a drink that’s both cooling and flavorful.

Why You’ll Love This Recipe

I like that this recipe is incredibly easy to make in advance, which means I can simply scoop and serve when it’s time to enjoy. The slushy texture makes it more exciting than a regular cocktail, and I can easily adjust the sweetness or strength to suit my taste. It’s great for summer gatherings, backyard BBQs, or relaxing on the porch.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• White rum

• Frozen orange juice concentrate

• Frozen lemonade concentrate

• Pineapple juice

• Sugar

• Water

• Lemon-lime soda (for serving)

Directions

1. I start by combining the sugar and water in a saucepan, heating just until the sugar dissolves to make a simple syrup.

2. I let the syrup cool completely before moving to the next step.

3. In a large freezer-safe container, I mix the cooled syrup with rum, orange juice concentrate, lemonade concentrate, and pineapple juice.

4. I stir everything until smooth, then cover and freeze overnight.

5. To serve, I scoop the frozen mixture into glasses and top each with lemon-lime soda for a fizzy finish.

Servings and timing

This recipe makes about 12 servings. It takes me around 10 minutes to prepare the mixture, plus at least 8 hours of freezing time before it’s ready to serve.

Variations

Sometimes I use spiced rum instead of white rum for a warmer, richer flavor. For a tropical twist, I replace some of the pineapple juice with coconut water or add a splash of coconut rum. If I want a less sweet drink, I reduce the sugar or use diet lemon-lime soda.

Storage/Reheating

I keep the rum slush in a sealed freezer container for up to 3 months. Since alcohol keeps it from freezing completely solid, it stays scoopable straight from the freezer. I give it a quick stir before serving to make sure the texture is even.

FAQs

Can I make this without alcohol?

Yes, I replace the rum with additional pineapple juice or coconut water for a non-alcoholic version.

Can I use dark rum instead of white rum?

Yes, but it will give the drink a deeper, more robust flavor.

How do I make it less sweet?

I cut back on the sugar or use unsweetened juices where possible.

Can I serve this in a punch bowl?

Yes, I scoop the frozen mixture into a punch bowl and pour soda over the top for a self-serve option.

Does it have to freeze overnight?

Freezing overnight gives the best texture, but at least 6–8 hours is needed for a proper slush consistency.

Conclusion

I enjoy making rum slush because it’s fun, refreshing, and always a crowd-pleaser. The icy texture and tropical flavor make it the perfect drink to cool down with, whether I’m hosting friends or just treating myself on a hot afternoon.
