Colcannon is a traditional Irish dish made with mashed potatoes and kale. In our version we leave the potatoes behind and sub cauliflower as the base of the dish. Next we add in spinach for a beautiful green hue and some added nutrition. The dish is finished with cream, avocado, and plenty of sour cream. Finally, some added butter gives it a traditional flavor that may even fool an Irishman!
Serve Colcannon as the Irish do with ham or bacon. You can make it a regular addition to your meal rotation with any meats you like. It comes together so quickly, uses convenience ingredients like frozen cauliflower and spinach, and really does hit the spot if you crave a spoonful of creamy mashed potatoes.
Substitute kale for the spinach, if you prefer, and feel free to add an extra dollop of full fat sour cream to the top when serving.
