What Are Colcannon Potatoes?

Colcannon potatoes are a traditional Irish side dish made by mixing creamy mashed potatoes with cabbage or kale and butter. The dish often includes additional ingredients like sautéed onions, green onions, and sometimes crispy bacon for extra flavor.

Originating in Ireland, colcannon has long been a comfort food staple and is especially popular during celebrations like St. Patrick’s Day. The potatoes are typically mashed until smooth and then combined with tender cooked cabbage, creating a rich, hearty dish with both creamy and slightly crisp textures.

  • 1 small white or yellow onion (diced)

Colcannon Potatoes FAQ

What else can I add to Colcannon Potatoes?

  • Try different greens! Leafy kale and Lacinato kale would work well here. You could also add spinach, but you’d need to also use a heartier leafy green since it would cook down a lot.
  • Spice it up! Add some red pepper flakes, cayenne pepper, or a seeded and diced jalapeño to incorporate some heat into this dish.
  • Make it Vegan or Vegetarian by omitting the bacon or swapping for a compliant alternative, use your favorite dairy-free milk in place of the whole milk (almond or full-fat coconut would work well here), and use plant-based butter.
  • Turn these into potato cakes by forming chilled leftovers into a patty or ball shape. Then, roll in some Panko bread crumbs and fry in vegetable oil until golden brown. Salt while hot, serve, and enjoy!
  • Make leftover potato gnocchi! All you need is flour, eggs, and leftover mashed potatoes. Serve as is or use to makeItalian Gnocchi Soup.
