Colcannon is a favorite Irish recipe made of potatoes, dairy, and cabbage or kale. Although usually associated with Saint Patrick's Day, colcannon is actually most seen on Irish tables on Halloween nights when the cook hides little trinkets in the mash, each representing fortune, poverty, or perhaps the chance of a future marriage.

There are as many recipes for this mashed potato dish as there are cooks in Ireland. Each household and region has a favorite way of cooking the colcannon. What seems to be commonplace in all of them is the presence of generous amounts of butter, potatoes and dairy, and cabbage or kale as the vegetable of choice to add volume and flavor to this tasty preparation.

For the perfect colcannon, choose floury potatoes, as these have more starch and less water and produce a fluffier mash. Varieties like Rosamunda, Desiree, Melody, Blue Congo, King Edward, Maris Piper, or Early Puritan are excellent potatoes for this dish. Serve the colcannon with boiled ham, Irish bacon, corned beef, Irish stew, or lamb chops for a hearty and flavorful true Irish meal.

Recipe Variations

  • Cabbage Colcannon: If finding fresh seasonal kale is not possible, replace it with shredded cabbage. Use a dark green leafy cabbage, such as Savoy or spring cabbage, soften it in a tablespoon of butter, and then briefly pulse it with the spring onions as you'd do with the kale.
  • Colcannon Cakes: A lovely and delicious alternative to colcannon is to shape it into cakes. For every 3 cups of colcannon, you'll need 1 cup of all-purpose flour, 1 egg, and an extra dash of salt and pepper. Mix everything, shape the mash like cakes, and fry in vegetable oil until golden brown on both sides. Top them with a poached egg and a dollop of hollandaise sauce. Making these cakes is also a great way of using up leftovers.
  • Bacon Colcannon: Fry 3 to 4 slices of bacon in a pan until crispy. Reserve 1 tablespoon of the bacon fat and discard the rest. Follow the recipe as instructed, but use 3 tablespoons of butter and the reserved tablespoon of fat to mash the potatoes. Mix the mash with the vegetables, and top with the bacon and just a small knob of butter instead of 2 full ounces.

Why Is It Called Colcannon?

Colcannon's name comes from the Gaelic cál and caineann, which stand for cabbage (or kale) and leek, respectively. Other linguistic interpretations of the name point to "white-headed cabbage."

What's the Difference Between Champ and Colcannon?

Champ and colcannon are both favorite Irish mashed potato dishes. They're very similar, though champ recipes tend to feature spring onions (scallions) alone, while colcannon adds cabbage, kale, or leeks.
