Colcannon is a traditional Irish dish, made with potatoes, cabbage, butter and milk. Serve these creamy mashed potatoes with Irish Beef Stew or a hearty and comforting meal.

What is Colcannon?

Colcannon is arguably the most well known of Irish potato dishes. Inexpensive, creamy, and comforting, this dish consists of mashed potatoes, milk, butter and cabbage. Scallions (or green onions) are sometimes used, and I decided to use them as well for the extra flavor. Typically a well is made in the center of the dish and a large knob of butter is placed there to melt, allowing everyone to get a little butter with their serving.

Ingredients for Colcannon - cabbage, green onions potatoes, milk, butter, salt and pepper.

Is Colcannon usually served on St. Patrick’s Day?

Actually, no. Colcannon is traditionally served on Halloween in Ireland, sometimes with various trinkets hidden in it. If someone finds one of the trinkets, it can predict that in the next year they will find wealth (a coin), marriage (a ring), spinsterhood (a thimble) or bachelorhood (a button). But that doesn’t mean you can’t enjoy this creamy and comforting dish any time of year.

Why is it called Colcannon?

The word Colcannon likely comes from the Gaelic word cal ceanneann meaning “white-headed cabbage”. Depending on the region, either cabbage or curly kale is used. According to the cookbook Real Irish Food by David Bowers, curly kale starts to show up in grocery stores in Ireland close to Halloween.

Cabbage or Kale?

Is cabbage or kale used in Colcannon? It can be either. As mentioned above, the Gaelic word cal ceanneann means “white headed cabbage”. However, now many people in Ireland only use curly kale. Most likely the greens used were what was cheap and readily available, so use what you prefer.

Is Colcannon the same as Champ?

Champ is similar to Colcannon, but Champ does not have cabbage. Champ is mashed potatoes with milk, butter and scallions.
