This vibrant sauce captures the essence of tropical flavors with a perfect balance of sweetness and heat. I developed this version to replicate the signature Bartaco experience at home.
With just a few simple ingredients and a blender, you’ll create a smooth, creamy sauce that elevates tacos, grilled meats, or even as a dip. The natural sweetness of plantains pairs beautifully with the subtle spice.
Ingredients for Bartaco Plantain Sauce
Eight simple ingredients blend into a creamy tropical sauce with sweet and spicy notes.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Plantains 🍌 | 2 whole | Very ripe, black skin preferred |
| Mayonnaise 🥄 | ½ cup | Vegan mayonnaise required |
| Jalapeño 🌶️ | 1 whole | Seeds removed for milder heat |
| Lime Juice 🍈 | 2 tbsp | Freshly squeezed preferred |
| Garlic Clove 🧄 | 1 clove | Peeled and minced |
| Cilantro 🌿 | ¼ cup | Fresh leaves and stems |
| Salt 🧂 | ½ tsp | Sea salt or kosher salt |
| Honey 🍯 | 1 tbsp | Use agave for vegan option |
Plantains are key here—look for ones with mostly black skin (the riper, the sweeter). Latin markets usually have the best selection, but Whole Foods or Trader Joe’s often carry them too. For the vegan mayo, Hellmann’s Vegan or Just Mayo are my go-tos. The jalapeño heat is subtle, so if you like more kick, leave some seeds in.
No ripe plantains? Overripe bananas work in a pinch (though the flavor shifts more toward banana than tropical). Out of vegan mayo? Cashew cream or blended silken tofu can substitute. Fresh cilantro is ideal, but flat-leaf parsley at half the amount gets you close. Swap honey for maple syrup or agave to keep it strictly vegan.
Sauce keeps 5-7 days in the fridge—store in a sealed jar. The flavor deepens overnight, so make it a day ahead if you can. Freezing isn’t ideal (texture changes), but it holds for 1 month in a pinch.

Step-by-Step Instructions for Plantain Sauce
This method transforms simple ingredients into a vibrant, balanced sauce with tropical depth.
Step 1: Roast the Plantains to Caramelized Perfection
Preheat your oven to 400°F. Peel the 2 whole Ripe Plantains and slice them into ½-inch thick rounds. The riper they are, the sweeter and more caramelized they’ll become—black skin is ideal here.
Arrange the slices on a parchment-lined baking sheet in a single layer. Roast for 20-25 minutes, flipping halfway through, until the edges turn deep golden brown and the flesh softens. You want them tender enough to mash easily with a fork but with some caramelized bits for texture. Remove from oven and let cool slightly.
Step 2: Blend the Aromatic Base
In a food processor or blender, combine the roasted plantains with the 0.5 cup Mayonnaise, 1 whole Jalapeño (seeds removed for milder heat), 2 tbsp Lime Juice, and 1 clove Garlic Clove. The jalapeño adds a bright, fresh heat that balances the sweetness.
Pulse until the mixture is mostly smooth but still has some texture—about 20-30 seconds. Scrape down the sides as needed. The plantains should break down completely, but tiny flecks of jalapeño and garlic are fine. This creates the creamy, flavorful foundation of your sauce.
Step 3: Finish with Fresh Herbs and Seasoning
Add the 0.25 cup Cilantro, 0.5 tsp Salt, and 1 tbsp Honey to the blender. The cilantro brings a fresh, citrusy note that brightens the sauce, while the honey rounds out the flavors with subtle sweetness.
Blend for another 10-15 seconds until the cilantro is finely incorporated and the sauce is smooth. Taste and adjust seasoning if needed—the lime and salt should create a perfect balance with the natural sweetness of the plantains and honey.
Step 4: Chill and Let Flavors Meld
Transfer the sauce to a bowl or jar and refrigerate for at least 30 minutes. This chilling time allows the flavors to meld together, and the sauce will thicken slightly as it cools.
The final texture should be creamy but pourable, with a vibrant green speckled appearance from the cilantro. Serve chilled or at room temperature—it pairs perfectly with grilled meats, tacos, or as a dip for chips and veggies. Store in an airtight container in the fridge for up to 5 days.
Pro Tips For Making Bartaco Plantain Sauce
- Use Black Plantains: Only use plantains that are nearly black—they’re sweeter and softer, which blends smoother into the sauce. I learned this the hard way after trying it with yellow ones and getting a starchy, bitter result.
- Roast the Jalapeño: Char the jalapeño directly over a gas flame or under the broiler for 5-7 minutes to mellow its heat and add smoky depth. Sounds weird, but it works and balances the sweetness perfectly.
- Strain the Blend: After blending, push the sauce through a fine-mesh strainer to remove any fibrous bits. This isn’t the prettiest step, but it guarantees a silky texture that’s restaurant-quality.
- Bloom the Garlic: Sauté the minced garlic in a little oil for 30 seconds before adding it to the blender—this removes the raw bite and makes the flavor richer. Skip the crowding in the pan; just do it in a small one.
Troubleshooting bartaco plantain sauce
Sauce Too Thin
If your sauce is watery, the plantains may not have been ripe enough. Roast them 5-10 minutes longer at 400°F to caramelize more, which reduces moisture. Alternatively, blend in 1 tbsp vegan mayo to thicken without changing flavor. 💡
Sauce Too Thick
Thick sauce can happen with overripe plantains. Thin it with 1-2 tsp lime juice or water, blending briefly to maintain smoothness. I prefer lime juice as it enhances the tropical flavor while adjusting texture.
Bitter Aftertaste
Underripe plantains can cause bitterness. Ensure they’re very ripe (black skin) before roasting. If bitterness persists, add 1 tsp honey or agave to balance the flavor. Stir well and taste before adding more.
Lacks Spice
For more heat, blend in ½ jalapeño with seeds or ¼ tsp cayenne pepper. Remember, the spice develops over time, so let it rest 30 minutes before adjusting further. I often add a pinch of cayenne for extra warmth.
Separation Issues
If the sauce separates after storage, simply stir vigorously or pulse in a blender for 5-10 seconds. To prevent this, ensure all ingredients are at room temperature before blending. Store in a tightly sealed jar.
Flavor Too Mild
Boost flavor by adding 1 extra garlic clove or ½ tsp salt. Fresh cilantro also intensifies the taste—blend in 2 tbsp more if needed. Let it sit for 1 hour to meld the flavors. 🌟

Frequently Asked Questions
Can I use green plantains instead of ripe ones?
No, green plantains are starchy and won’t provide the sweetness needed. Always use very ripe ones with mostly black skin for the best flavor.
How long does this sauce keep in the fridge?
It stays fresh for 5-7 days in an airtight container. The flavors actually improve after 24 hours as they meld together.
What can I use instead of jalapeño for less heat?
Swap in ½ a bell pepper for mildness or 1 poblano pepper for a milder, smoky flavor. Remove all seeds for the least spice.
Why did my sauce turn out grainy?
This usually means the plantains weren’t fully roasted. Ensure they’re soft and caramelized before blending. A high-speed blender helps achieve a smooth texture.
