Ingredients:
- 4 russet potatoes (2 to 2 1/2 pounds), peeled and cut into 1 1/2-inch pieces
- Salt, to taste
- 5 to 6 tablespoons unsalted butter, plus more for serving
- 3 lightly packed cups chopped kale, cabbage, chard, or other leafy green
- 3 green onions, minced (about 1/2 cup)
- 1 cup milk or cream
Instructions:
Boil the potatoes:
- Put the potatoes in a medium pot and cover with cold water by at least an inch. Add 2 tablespoons of salt, and bring to a boil.
- Boil until the potatoes are fork tender, 15 to 20 minutes. Drain in a colander.
Cook the greens and the green onions with butter:
- Return the pot to the stove and set over medium-high heat. Melt the butter in the pot and once it’s hot, add the greens.
- Cook the greens for 3 to 4 minutes, or until they are wilted and have given off some of their water.
- Add the green onions and cook 1 minute more.
Mash the potatoes with milk or cream and greens:
- Pour in the milk or cream, mix well, and add the potatoes. Reduce the heat to medium.
- Use a fork or potato masher and mash the potatoes, mixing them up with the greens.
- Add salt to taste and serve hot, with a knob of butter in the center.
