Colcannon Potatoes
Colcannon is a traditional Irish potato dish that consists of creamy potatoes with green cabbage, scallions, cream, and butter. In Ireland, this is served daily in Irish pubs and also on Halloween. But in America, where everyone is Irish on St. Patrick’s Day, this savory cabbage and potato dish completes a Irish feast for all.

What is Colcannon?
Colcannon is an Irish dish that consists of mashed potatoes with sauteed green cabbage and green onions, then drizzled with butter and warm cream. It is similar to “Champ,” another Irish potato dish.
What’s the difference between Colcannon and Champ?
Colcannon consists of mashed potatoes with either cabbage or kale, heavy cream, scallions, and butter. Champ doesn’t include cabbage or kale-it consists of mashed potatoes, scallions, heavy cream and butter.

Recipe Tips
- For the most authentic texture for Colcannon, use a non-waxy potato like a Russet, Idaho or Yukon Gold potato
- When you mash the potatoes, don’t overdo it.The final texture of colcannon should be semi-chunky, not smooth like whipped potatoes
- Heat the cream slightly before adding it to the potatoes; this ensures a smooth texture without separation of the fat or cooling the cooked potatoes
FAQ’s
Russet, Idaho or Yukon Gold potatoes are best for Colcannon because they are more starchy and fluffy than waxy potatoes.
Warmed cream ensures the fat doesn’t separate and the potato dish doesn’t get gummy.
After refrigeration, the Colcannon will thicken. The best way to reheat it is to place it in a skillet or saucepan on the stovetop, cook on low heat for a few minutes, and add a little warm cream if needed to thin the potatoes.
Yes. Based on the USDA, Colcannon can be made up to 3-4 days in advance.
According to the USDA and its recommendation of “Danger Zone Temperatures,” warm dishes should be refrigerated within 2 hours of cooking.
Storage and reheating
Refrigerate in an airtight container for up to 3-4 days. For best results, reheat on the stovetop on low heat. Potatoes thicken upon refrigeration, so you may need to add a little warm cream or water.
