  • 2 pounds Yukon gold or Russet potatoes peeled and cut into chunks
  • 6 tablespoons unsalted butter or ghee
  • 4 cups (lightly packed) chopped kale or cabbage
  • 3 green onions thinly sliced
  • ½ cup milk any type works
  • salt and pepper to taste


  • Place the potatoes in a large pot and cover with cold water, with about an inch of water above the potatoes. Bring to a boil and cook for 15-20 minutes, or until fork tender.
  • Meanwhile, melt the butter in a separate large pot over medium heat and add the chopped kale. Cook the kale for 3-4 minutes, until wilted. Add the green onions (reserve a small amount for garnish) and stir together for another minute.
  • Drain the potatoes in a colander, then add them to the kale. Pour in the milk, and season with salt and pepper. Mash the potatoes with the greens until fluffy and well combined.
