Alboronía o Boronía Criolla: Colombian Eggplant & Plantain Mash
Alboronía (also known as Boronía Criolla) is a deeply traditional side dish from the Colombian Caribbean coast. It is a fantastic, savory-sweet mash of eggplants and ripe plantains. This iconic dish actually traces its profound historical origins back to Arab-Andalusian cultures, but was entirely adopted and adapted using the magnificent local ingredients of the Caribbean.
The secret to this 35-minute recipe is the preparation of the eggplants. Whether you choose to boil them with lemon to remove their bitterness or roast them directly over a flame for a smoky touch, mashing them together with sweet plantains and a rich garlic-onion sofrito creates an absolutely unforgettable flavor profile!

Alboronía o Boronía Criolla (Eggplant & Plantain Mash)
A sweet and savory Caribbean coastal classic! A rich mash of eggplants and ripe plantains mixed with a garlic and onion sofrito.
Ingredients
- 3 Eggplants Berenjenas
- 1 Ripe plantain Plátano maduro
- 1 Medium red onion
- 1 Garlic clove
- 1 tablespoon Cooking oil
- 1 Lemon For juice
- Salt to taste
- Queso costeño Salty white cheese, diced – Optional
- Chicharrón de cerdo Fried pork belly, diced – Optional
Instructions
Option 1 (The Boiled Method)
- Prep the eggplants: The very first step is to peel the eggplants and place them in a pot of boiling water. Add salt and the juice of the lemon. Let them cook for 20 minutes. (Chef's Hack: The lemon juice is crucial; it prevents the eggplants from oxidizing/darkening and completely removes their natural bitterness!) Once soft, remove, drain well, and set aside.
- Prep the plantain: Boil the ripe plantain (with its skin still on) in a separate pot of water for 10 minutes until completely soft. Drain it, peel it, and let it rest.
- Mash: Place the drained eggplants and the peeled ripe plantain into a large bowl. Using a fork, mash them together vigorously until you achieve a homogeneous, thick puree.
- The Sofrito: In a pan, heat the cooking oil. Sauté the julienned red onion and the finely minced garlic. Once the onions are translucent, add the eggplant and plantain puree to the pan.
- Final simmer: Mix well and let everything cook together for about 10 minutes. If desired, fold in the diced chicharrón or queso costeño right at the end. Serve hot!
Option 2 (The Roasted/Smoky Method)
- Roast the base: Place the whole eggplants and the whole unpeeled ripe plantain directly on the stovetop over a low flame (or ideally, over hot charcoal). Roast them for about 10 minutes, turning occasionally, until they are completely tender and charred on the outside.
- Peel and mash: Carefully remove the charred skins from the eggplants and the plantain. Using a fork or a masher, crush the flesh together until you form a rustic puree.
- The Sofrito: Heat the oil in a pan and prepare a sofrito with the finely chopped red onion and minced garlic. Let it fry for a few minutes.
- Combine and serve: Add the roasted puree to the sofrito, stirring very well to integrate all the flavors. Cook for a few more minutes. Top with the optional chicharrón or queso costeño and serve immediately!

Notes
- The Perfect Companions: Alboronía is traditionally served as a phenomenal side dish for hearty meat plates, almost always accompanied by white rice, crispy patacones, casabe (yuca flatbread), or fried yuca.
- Historical Migration: The incredible cultural exchange that birthed this dish in Colombia was a direct consequence of migration and colonization, taking an ancient Arab-Andalusian recipe and reimagining it with the sweetness of native tropical plantains.
- Health Benefits: Eggplant is a famously hypocaloric vegetable (extremely low in calories), making this base puree absolutely ideal for weight-loss diets. Furthermore, eggplant is a powerful natural antioxidant that strongly promotes healthy biliary emptying!
