Mangu is a traditional Dominican dish made from boiled and mashed green plantains. It's a staple breakfast item that is often enjoyed with a variety of toppings, including sautéed red onions. This dish is not only delicious but also incredibly comforting and easy to prepare.
If you're not familiar with green plantains, they are a starchy fruit similar to bananas but less sweet and more firm. They are essential for making mangu and can be found in most supermarkets, usually in the produce section. Make sure to pick plantains that are green and firm to the touch.

Ingredients for Mangu Recipe
Green plantains: These are the main ingredient for mangu, providing a starchy base that is mashed to create the dish.
Water: Used to boil the plantains until they are tender.
Salt: Enhances the flavor of the plantains during boiling.
Butter: Adds richness and creaminess to the mashed plantains.
Red onions: Sautéed and used as a flavorful topping for the mangu.
Olive oil: Used to sauté the red onions, adding a subtle richness.
Vinegar: Adds a tangy flavor to the sautéed onions, balancing the richness of the mangu.
Technique Tip for This Recipe
When mashing the plantains, add a bit of the boiling water gradually to achieve a smoother consistency. This helps to make the mangu creamier and easier to mash. Additionally, ensure the onions are cooked until they are translucent and slightly caramelized for a richer flavor when combined with the vinegar.

How to Store or Freeze This Dish
Allow the mangu to cool completely before storing. This prevents condensation, which can make the plantains soggy.
Transfer the cooled mangu into an airtight container. This helps maintain its freshness and prevents it from absorbing other odors in the fridge.
Store the mangu in the refrigerator for up to 3 days. Beyond this, the texture and flavor may start to degrade.
For longer storage, consider freezing. Portion the mangu into individual servings. This makes it easier to thaw only what you need.
Place the portions into freezer-safe bags or containers. Ensure you remove as much air as possible to prevent freezer burn.
Label the containers with the date. This helps you keep track of how long the mangu has been stored.
When ready to use, thaw the mangu in the refrigerator overnight. This gradual thawing helps maintain its texture.
Reheat the mangu gently on the stovetop or in the microwave. Add a splash of water or butter to help restore its creamy consistency.
For the sautéed onions, store them separately in an airtight container in the fridge. They can be kept for up to 3 days.
Reheat the onions in a pan over low heat until warmed through. This helps retain their flavor and texture.
