This hearty Kenyan side dish combines tender green plantains and potatoes mashed together with sautéed onions, tomatoes, and warming spices.

The chunky texture and savory flavor make it a satisfying alternative to plain mashed potatoes.

Ingredients

For the mash

  • 3 large green (unripe) plantains
  • 4 medium russet potatoes
  • 1 tsp salt for boiling water

For the spice base

  • 2 tbsp vegetable oil
  • 1 large yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 2 medium tomatoes, diced
  • 1 tsp curry powder
  • 1/2 tsp ground turmeric
  • 1/2 tsp black pepper
  • 1 tsp salt, to taste

Directions

  1. Peel the green plantains and potatoes with a sharp knife, then cut them into 1-inch chunks for even cooking.
  2. Place the plantains and potatoes in a large pot, cover with cold water, add 1 tsp salt, and bring to a boil. Cook for 20-25 minutes until fork-tender.
  3. While the vegetables cook, heat oil in a skillet over medium heat. Sauté the chopped onion for 4-5 minutes until soft and translucent.
  4. Add the minced garlic, diced tomatoes, curry powder, turmeric, and black pepper. Cook for 5-7 minutes, stirring, until the tomatoes break down into a thick, fragrant paste.
  5. Drain the cooked plantains and potatoes well, reserving 1/4 cup of the cooking water.
  6. Return the drained vegetables to the warm pot over low heat. Add the prepared spice mixture and mash with a potato masher, leaving a chunky texture.
  7. Stir in the reserved cooking water a little at a time until the mash is moist but holds its shape. Taste and adjust salt.
  8. Serve hot as a side dish with grilled meats, beef stew, or sautéed collard greens.

Cook’s Notes

  • Use firm, fully green plantains; yellow or ripe ones will make the mash sweet and mushy rather than savory.
  • For extra nutrition and color, stir in 2 cups of finely chopped spinach or collard greens during the final minute of mashing.
  • Resist over-mashing; authentic mchakamchaka should remain chunky, not smooth like Western mashed potatoes.
  • The tomato-onion spice paste can be prepared up to 3 days ahead and refrigerated to save time on busy weeknights.
  • Leftovers reheat well in a covered pan with a splash of water to restore moisture.
