Instructions

  1. Step 1: In a large pot, bring 4 cups water and 1 tsp salt to a boil. Add 3 peeled and sliced green plantains and cook for 20-25 minutes until very tender when pierced with a fork.
  2. Step 2: Drain the plantains, reserving 1/2 cup cooking water. Mash plantains with 2 tbsp butter and 2 minced garlic cloves, adding reserved water gradually to achieve a smooth, creamy texture.
  3. Step 3: In a skillet, heat 2 tbsp olive oil over medium heat. Add 1 medium thinly sliced red onion and sauté for 5 minutes until soft.
  4. Step 4: Stir in 1 tbsp white vinegar and 1/4 tsp black pepper, cooking for an additional 2 minutes until onions are caramelized and tangy.
  5. Step 5: Serve the mashed plantains topped with the sautéed onions for a savory, traditional Dominican dish.

How do I store leftover Spiced Dominican Mangu with Sautéed Onions?
