Colcannon is a traditional Irish mashed potato dish made with creamy potatoes, sautéed kale, garlic, and green onions. This recipe combines smooth mashed potatoes with tender greens for a hearty, flavorful side dish perfect for pairing with meats, stews, or as a comforting meal on its own.

Ingredients

3 pounds Russet potatoes, peeled or unpeeled
Fine sea salt and freshly ground black pepper
1 bay leaf
5 tablespoons butter, divided
4 cloves garlic, pressed or minced
4 cups loosely packed chopped kale, tough stems removed (~2.5 ounces)
4 green onions, thinly sliced and divided
4 ounces cream cheese, at room temperature
1/2 cup whole milk

Instructions

Boil the Potatoes: Cut the potatoes into evenly sized 1-inch chunks and place them in a large stockpot. Cover with cold water so the water level is about 1 inch above the potatoes. Add 2 teaspoons salt and the bay leaf. Bring to a boil over high heat and cook for 10–12 minutes or until a knife slides in easily with little resistance. Drain the potatoes thoroughly and discard the bay leaf.
Sauté Garlic and Kale: While the potatoes drain, melt 1 tablespoon of butter in the same stockpot over medium-high heat. Add the garlic and sauté for 1 minute, stirring occasionally. Add the kale and cook for 1–2 minutes more until wilted and tender. Remove from heat.
Mash Together: Return the drained potatoes to the stockpot. Add the sautéed kale and garlic, half of the sliced green onions, cream cheese, remaining butter (cut into cubes), and milk. Use a potato masher to mash until the mixture is smooth and well combined, stirring occasionally with a spatula to help mix evenly.
Season: Taste and adjust seasoning with additional salt and freshly ground black pepper as needed.
Serve: Serve warm, garnished with the remaining green onions.
