Colcannon is probably my favorite St. Patrick's Day recipe. It combines the lovely, spring-is-finally-here-greenness of kale and leeks with the always alluring comfort of buttery mashed potatoes.

Ingredients

Original recipe (1X) yields 6 servings

  • 3 large russet potatoes, peeled and quartered

  • 2 tablespoons butter at room temperature

  • 4 ounces kale, trimmed and chopped

  • 1 leek, light parts only, rinsed and chopped

  • 1 bunch green onions, chopped, white and green parts separated

  • 2 tablespoons butter at room temperature

  • salt and ground black pepper to taste

  • ¼ cup heavy whipping cream

  • 2 tablespoons butter, for serving

  • ¼ cup green onions to garnish

Directions

  1. Boil potatoes in a large pot of salted water until tender, about 10 minutes. Drain and transfer potatoes to a large bowl. Add 2 tablespoons butter and lightly mash the potatoes.

  2. Boil kale and leeks in a large pot of water until tender, 5 to 7 minutes. Drain and transfer kale and leeks to a blender. Add white parts of the green onions and 2 more tablespoons butter; blend until smooth, scraping down sides as needed, 1 to 3 minutes.

  3. Stir pureed kale mixture into the bowl of potatoes and continue to mash. Season with salt and black pepper to taste. Add cream and stir until desired texture. Top with 2 tablespoons butter and green parts of the green onions.

Chef's Note:

You can substitute kale with other leafy greens such as Swiss chard or cabbage.
