Ingredients
- 3 medium green plantains (peeled and cut into 2-inch pieces)
- 4 cups water
- 1 tsp salt
- 3 tbsp unsalted butter
- 1 medium red onion (thinly sliced)
- 2 tbsp white vinegar
- 1 tbsp olive oil
- 1/4 tsp black pepper
- 1 tbsp fresh parsley (chopped, optional)
Instructions
- Step 1: In a large pot, bring 4 cups water and 1 tsp salt to a boil. Add 3 peeled and cut green plantains and reduce heat to medium-low. Simmer for 20-25 minutes until plantains are very tender when pierced with a fork.
- Step 2: Drain the plantains and return them to the pot. Add 3 tbsp unsalted butter and mash with a potato masher or fork until smooth and creamy. Keep warm.
- Step 3: While plantains cook, heat 1 tbsp olive oil in a small skillet over medium heat. Add 1 thinly sliced medium red onion and sauté for 5 minutes until softened and slightly caramelized.
- Step 4: Stir in 2 tbsp white vinegar and cook for another 2 minutes until the vinegar reduces slightly, then season with 1/4 tsp black pepper.
- Step 5: Spoon the mashed plantains onto plates and top with the sautéed red onions. Garnish with 1 tbsp chopped fresh parsley if desired and serve immediately.
