Ingredients for banana rum soup recipe royal caribbean

| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic base |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated nutmeg better |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening if needed |

The bananas are the heart of this soup—pick the blackest, spottiest ones you can find at the grocery store. They’re sweeter and easier to mash. Trader Joe's or Whole Foods usually have the riper ones, but any store’s produce section works if you check the bananas yourself. Spiced rum? Captain Morgan or Kraken are solid choices, but any dark or gold rum with warm spices will do. The coconut milk should be full-fat—canned brands like Thai Kitchen are perfect for this. If you’re using a lighter coconut milk, add an extra splash of coconut cream at the end for richness.
No spiced rum? Apple cider or bourbon can stand in, but the flavor will be different. Fresh nutmeg is a game-changer if you’ve got it—pre-grated loses potency fast. For the broth, low-sodium is key—you don’t want to overpower the natural sweetness of the bananas. The flour is just a backup if the soup needs thickening, but honestly, the bananas and coconut milk should give you enough creaminess. If you’re feeling fancy, swap the granulated sugar for coconut sugar—it’s got a caramel-like depth that pairs perfectly with the rum.
This soup tastes even better the next day as the flavors meld. Store leftovers in an airtight container for up to 5 days in the fridge, or freeze for 3 months—just thaw overnight in the fridge. The toasted coconut adds a nice crunch, but it’s optional. If you’re making this ahead, toast the coconut fresh before serving so it stays crisp. A drizzle of extra rum on top when serving? Totally worth it—trust me on this.

Step-by-step instructions for banana rum soup
This velvety soup brings tropical flavors to life with a perfect balance of spiced rum and creamy coconut.
🍳 Step 1: Sauté Aromatics Until Fragrant
Heat the 2 tablespoons extra-virgin olive oil in a large pot over medium heat. Add the diced yellow onion and cook for 5 minutes until softened and translucent. Here's where the magic starts—I like to see the onions release their sweetness before adding anything else.
Add the 4 cloves minced garlic and cook for another 30 seconds until fragrant. You'll know it's ready when the kitchen smells like a Caribbean sunset. Be careful not to let the garlic brown—it should just perfume the onions. This aromatic base forms the flavor foundation for your entire soup.
🍳 Step 2: Build the Spiced Rum Base
Pour in the ½ cup spiced rum and let it simmer for 2 minutes until the alcohol smell dissipates completely. I like to stir occasionally, watching as the rum infuses the onions and garlic with its warm, caramel notes. This step is crucial—it's what gives your soup that authentic Royal Caribbean-inspired depth.
Add the 1 teaspoon ground cinnamon and ½ teaspoon ground nutmeg, stirring constantly for 30 seconds to toast the spices slightly. You'll see them dance in the pot, releasing their aromatic oils. This is where the warm, comforting spices come alive—don't skip this step, even if it seems small.
🍳 Step 3: Blend the Creamy Banana Base
Peel and slice the 4 whole ripe bananas and add them to the pot along with the 3 cups vegetable broth and 2 tablespoons granulated sugar. Bring everything to a gentle boil, then reduce heat to medium-low and let it simmer for 10 minutes, stirring occasionally. The bananas should soften completely and blend into the broth.
For a truly silky texture, transfer half of the mixture to a blender and blend until completely smooth. Here's the thing—blending just half keeps some texture in your soup while still achieving that velvety consistency. Pour the blended mixture back into the pot and stir well. If you prefer it extra creamy, you can blend everything, but I like that slight texture contrast.
🥘 Step 4: Finish with Coconut Milk and Season
Stir in the 1 can coconut milk and the 1 tablespoon all-purpose flour. The flour helps thicken the soup slightly, giving it that perfect body. Bring the soup back to a gentle simmer and cook for 5-7 minutes, stirring frequently, until it reaches your desired thickness. You're aiming for a consistency that coats the back of a spoon but isn't gluey.
Taste and adjust the seasoning with the ½ teaspoon salt and ¼ teaspoon black pepper. I usually need a bit more salt here—remember, the rum and coconut milk are already adding flavor. The soup should be sweet, spiced, and just slightly salty. If it needs more depth, you can add a splash more rum, but start with just 1 teaspoon to taste.
🍽️ Step 5: Serve Warm with Toasted Coconut
Ladle the soup into bowls and garnish with 2 tablespoons toasted coconut. The toasted coconut adds a beautiful texture contrast and enhances the tropical flavors. Serve immediately while warm—this soup is best enjoyed fresh from the pot when all the flavors are at their peak.
For that extra Royal Caribbean touch, I like to serve it with a sprinkle of freshly grated nutmeg on top. The warmth of the spices, the creaminess of the coconut, and the sweetness of the rum all come together in every spoonful. And trust me, the first sip will transport you straight to paradise.
Pro Tips For Making Banana Rum Soup Recipe Royal Caribbean
- Peel Bananas First: I learned this the hard way—peeling bananas before cooking saves time and keeps your pot from sticking. Slicing them raw means less mess when the soup thickens, and you won’t waste time scrubbing a burnt-on banana film later.
- Sweat the Onion Low: Medium heat is your friend here. Let that onion melt into the pot for 8-10 minutes until it’s translucent and just starting to caramelize—no browning. Rushed onions add bitterness, and you want this soup to taste like comfort, not regret.
- Simmer, Don’t Boil: Once the broth and coconut milk come together, keep it at a gentle simmer. Boiling burns off the rum’s spice notes and turns the coconut milk grainy. A slow bubble (barely visible) keeps the flavors rich and the texture velvety—trust me, it’s worth the wait.
- Strain the Bananas: After simmering, force the banana mixture through a fine-mesh strainer. It’s messy, but the result is a silky soup without chunks—no one wants a surprise bite of overripe banana. Save the pulp for smoothies or pancakes; it’s still delicious.
Essential equipment for this recipe
Pot Essentials
Start with a heavy-bottomed Dutch oven—I recommend a Le Creuset 5-quart—to distribute heat evenly and prevent scorching. The deep sides make stirring easier, and the material retains heat beautifully for that slow simmer.
If you don’t have a Dutch oven, a large stainless steel pot with a tight-fitting lid works just as well. 🥘
Blender for Silkiness
A high-speed blender like the Ninja BN601 is perfect for achieving that ultra-smooth texture. If you’re blending just half the soup, a smaller immersion blender (like the Ninja ICB111) works too—it’s less messy and saves cleanup time.
Just be sure to remove the hot mixture from the pot first to avoid splattering.
Measuring Tools
Precision matters here, especially with spices and rum. Use a stainless steel measuring spoon set for accurate measurements of cinnamon, nutmeg, and sugar. A digital kitchen scale (like the OXO Good Grips) is ideal for weighing bananas if you prefer consistency.
For liquids, a liquid measuring cup with clear markings ensures you get the exact ½ cup rum and 3 cups broth needed.
Toasted Coconut Prep
For that perfect garnish, a small dry skillet or toaster oven is essential. Toast 2 tablespoons unsweetened coconut flakes over medium-low heat for 2-3 minutes, stirring constantly, until golden.
Keep an eye on them—they burn quickly! A fine-mesh strainer helps catch any stray flakes while keeping your workspace clean. 🥥
Optional Rum Reduction
If you want to elevate your soup with a rum reduction drizzle, grab a small saucepan and simmer ¼ cup spiced rum with 1 tablespoon sugar until reduced by half.
A ladle makes it easy to drizzle over the finished soup. This step adds a glossy, caramelized finish that feels restaurant-worthy.

Frequently asked questions
Can I make this banana rum soup without alcohol?
Yes! Swap the ½ cup spiced rum with ½ cup apple cider or apple juice for a non-alcoholic version. The cider adds a subtle sweetness that complements the bananas beautifully. For extra depth, add 1 teaspoon vanilla extract to mimic the rum's warmth.
How do I know when the bananas are ripe enough?
Look for bananas with black spots covering most of the peel—these are the sweetest and easiest to mash. The blacker the spots, the better! If you can't find ripe bananas, you can speed up ripening by placing them in a paper bag with an apple for 1-2 days at room temperature.
Can I use frozen bananas instead of fresh?
Frozen bananas work, but they'll add a slightly icy texture to your soup. Thaw them first, then peel and slice as usual. For best results, use fresh ripe bananas—they dissolve smoothly into the broth, creating that signature velvety texture without any graininess.
Is this soup kid-friendly?
Most kids love the sweet, creamy flavors! Just skip the rum entirely and use apple juice instead. Serve it warm with a sprinkle of cinnamon on top—they'll think it's dessert! For extra appeal, blend the entire soup for a smoother texture that's easier for little ones to enjoy.
How can I make this soup thicker or thinner?
For a thicker soup, stir in 1 more tablespoon of flour and simmer for 2-3 minutes. Need it thinner? Add ½ cup more broth or coconut milk and stir well. The key is to adjust gradually—start with small amounts and taste as you go to avoid over-thickening or over-diluting.
