This banana rum soup recipe transports you straight to the sun-drenched decks of Royal Caribbean, where warm spices and golden bananas create a symphony of tropical flavors.
The secret lies in slow simmering plantains with cinnamon and nutmeg, then blending them into velvety perfection with a touch of rum for depth. I've recreated the signature dish you'd find on cruise menus—rich, comforting, and impossible to resist.
The beauty of this recipe is its balance: sweet bananas caramelize into a natural syrup, while warm spices like allspice and vanilla extract infuse every spoonful with Caribbean warmth. A splash of dark rum (or rum extract for non-alcoholic versions) adds that signature cruise-line touch without overpowering the natural sweetness.
The texture is what truly sets it apart—smooth yet substantial, with just enough body to satisfy.
What makes this soup special is how it transforms simple ingredients into something extraordinary. Plantains replace regular bananas for their firmer texture, while coconut milk creates a luxurious base that feels indulgent yet light.

Ingredients for banana rum soup recipe royal caribbean
Six ripe plantains and a splash of rum—this is your ticket to Royal Caribbean's signature tropical escape.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Plantains 🍌 | 1 ½ lb | Yellow with black spots, peeled |
| Fresh Bananas 🍌 | 2 medium | Ripe but firm, peeled |
| Dark Brown Sugar 🍚 | ½ cup | Packed, for caramelization |
| Coconut Milk 🥥 | 1 can | Full-fat, 13.5 oz can |
| Dark Rum 🍹 | ½ cup | 100-proof, aged 3+ years |
| Vanilla Extract 🍯 | 1 tsp | Pure Madagascar bourbon |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated for depth |
| Ground Allspice 🌶️ | ¼ tsp | Warm, Caribbean-inspired |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Unsalted Butter 🧈 | 2 tbsp | European-style, 82% fat |
| Heavy Cream 🥛 | ¼ cup | Full-fat for richness |
The plantains are the star, so don't skimp. Look for ones with black spots—that's when they're perfectly ripe. Trader Joe's or Latin markets usually have the best selection, but any grocery store will work. Fresh bananas should be ripe but still firm to the touch. The rum? Captain Morgan or Gosling's are the cruise line's go-to, but any dark rum with at least 3 years aging will do. For the spices, Penzeys bulk bins are perfect—just make sure they're freshly ground. The coconut milk needs to be full-fat for that luxurious texture, and Thai Kitchen cans are my secret weapon for consistency.
No rum? Rum extract plus a splash of vanilla gets you close, though it won't have the same depth. Short on plantains? Double the bananas and add 1 tbsp brown sugar to compensate. The butter and cream are non-negotiable for that velvety finish—European-style butter has more fat, which means richer flavor. Want to make this ahead? Prepare everything up to blending, then reheat gently with a splash of coconut milk. The spices can be toasted in a dry pan for 30 seconds before adding to the soup—trust me on this—it brings out their aroma.
This soup tastes even better the next day as the flavors meld. Store it in an airtight container in the fridge for up to 5 days. For freezing, portion into individual containers—3 months max. The rum flavor actually improves with time, so don't hesitate to make a big batch. Serve it warm with crusty bread or a dollop of whipped cream for that true cruise-line experience. Leftovers reheat beautifully—just stir in a splash of coconut milk to restore creaminess.

Step-by-step instructions for banana rum soup
Transport yourself to the Caribbean with this velvety rum-infused creation—rich, spiced, and perfectly balanced.
Sauté the Aromatics and Caramelize the Sugar
In a large, heavy-bottomed pot, melt the 2 tablespoons unsalted butter over medium heat. Once fully melted and foaming, add the 2 medium fresh bananas, sliced into ¼-inch rounds, and the 1.5 lb ripe plantains, peeled and cut into ½-inch cubes. Cook for 5 minutes, stirring occasionally, until the fruit begins to soften slightly.
Here's where the magic happens: Sprinkle in the ½ cup packed dark brown sugar and stir constantly for 3-4 minutes until it turns a deep amber color. You're looking for a rich caramelized depth—this is the soul of your soup. If the sugar starts to burn, reduce heat slightly but keep stirring. The aroma will fill your kitchen with tropical warmth.
Build the Spiced Rum Base
Pour in the ½ cup dark rum and scrape up any browned bits from the bottom of the pot—this is pure flavor. Let it simmer for 2-3 minutes until the alcohol smell dissipates (about 75% of it cooks off). Then, add the 1 can coconut milk, stirring well to combine. The mixture should be smooth and creamy, with a subtle golden hue from the caramelization.
In a small bowl, whisk together the 1 teaspoon ground cinnamon, ½ teaspoon ground nutmeg, ¼ teaspoon ground allspice, ½ teaspoon salt, and ¼ teaspoon black pepper. Sprinkle this spice blend over the soup and stir vigorously. Let it simmer for 5 minutes to allow the spices to bloom and infuse the liquid. You'll notice the aroma deepen—this is the Caribbean spice profile at work.
Simmer and Blend to Perfection
Reduce the heat to low and let the soup simmer gently for 15 minutes, stirring occasionally. This slow cook allows the flavors to meld and the coconut milk to thicken slightly. Taste the mixture now—it should be sweet, spiced, and rich, but still have room for the finishing touches.
Using an immersion blender, blend the soup until completely smooth. If you don't have an immersion blender, carefully transfer the soup in batches to a countertop blender, blending until silky. The texture should be velvety, like a cross between a custard and a light curry. Return the blended soup to the pot and stir in the 1 teaspoon vanilla extract. This adds a subtle floral note that rounds out the flavors beautifully.
Finish with Cream and Serve Warm
Increase the heat to medium-low and stir in the ¼ cup heavy cream. Simmer for another 3-4 minutes, just until the cream is fully incorporated and the soup reaches a luxurious consistency. The cream adds a luxurious mouthfeel without overpowering the tropical flavors.
Taste and adjust the seasoning if needed—you might want to add a pinch more salt or a splash of rum to intensify the flavor. Ladle the soup into bowls and serve immediately, garnished with a sprinkle of ground cinnamon or a drizzle of extra dark rum for that authentic Royal Caribbean touch. Each spoonful should be a perfect balance of sweet, spicy, and creamy—pure tropical escape.
Pro Tips For Making Banana Rum Soup Recipe Royal Caribbean
- CHAR THE PLANTAINS FIRST: I used to toss them in raw, thinking they’d soften like bananas—but no. Slice the plantains first, then sear them in a dry pan over medium-high heat until they’re blackened in spots. This caramelizes their natural sugars, giving that deep, smoky backbone the Royal Caribbean version nails. (Yes, even if you’re impatient like me.)
- USE SPLIT COCONUT MILK: The canned stuff works, but split coconut milk—especially the thick cream from the top—adds a richer, creamier texture without thinning the soup. Save the watery part for another dish, and you’ll get that luxurious mouthfeel without drowning the flavors. (Your future self will notice the difference.)
- SIMMER THE RUM LOW: Pouring in the rum and boiling it off immediately strips the flavor. Instead, add it after the plantains and bananas have softened, then reduce heat to a gentle simmer. Let it mingle for 5-7 minutes—just enough to infuse without turning the soup into a boozy punch. (Sounds weird, but it works.)
- SWEAT THE BROWN SUGAR: Dumping dark brown sugar at the end just makes the soup cloyingly sweet. Bloom it first: melt it with a splash of coconut milk over low heat for 2-3 minutes until it turns glossy and aromatic. This deepens its molasses notes and prevents graininess. (This isn’t the prettiest method, but it’s the tastiest.)
Best sauces and condiments for this recipe

Frequently asked questions
Can I make this banana rum soup without alcohol?
Replace the ½ cup dark rum with ½ cup rum extract mixed with 1 teaspoon vanilla extract and 1 tablespoon maple syrup for a non-alcoholic version. The flavor won't be identical, but it will still capture the warm, spiced essence of the Caribbean. For extra depth, add an extra pinch of cinnamon and nutmeg to compensate for the missing rum aroma.
How do I know when plantains are ripe enough for this recipe?
Look for plantains with black spots on yellow skin—they're perfectly ripe for this soup. The flesh should be soft when gently pressed, but not mushy. If you can't find ripe plantains, substitute with 2 extra bananas and add 1 extra tablespoon brown sugar to balance the flavor. Just remember, plantains add a firmer texture that holds up better during blending.
Can I make this soup ahead of time for a cruise-themed dinner party?
Yes! Prepare everything up to the blending step, then refrigerate in an airtight container for up to 5 days. When ready to serve, simply reheat gently over low heat, stirring in a splash of coconut milk to restore creaminess. The flavors actually improve overnight as the spices meld. For freezing, portion into individual containers—this soup stays fresh for 3 months in the freezer.
What's the best way to serve this soup on Royal Caribbean-style plates?
Garnish with a cinnamon-sugar rim on your bowls (mix 1 tbsp brown sugar + ½ tsp cinnamon, dip bowl edges in melted butter). Top each serving with a drizzle of spiced rum reduction (simmer ¼ cup rum + 1 tbsp brown sugar + ½ tsp cinnamon until syrupy) and a sprinkle of toasted coconut flakes for that authentic cruise-line presentation. Serve with warm plantain chips on the side for crunch.
Why does my soup taste too sweet after blending?
This usually happens when the sugar caramelizes too much or the plantains/bananas weren't ripe enough. To fix it, stir in 1 teaspoon lime juice or ½ teaspoon vanilla extract to balance the sweetness. For future batches, reduce the brown sugar to ⅓ cup and let the natural sweetness of ripe plantains shine. A pinch of black pepper or allspice can also help cut through excess sweetness while maintaining the Caribbean flavor profile.
