Classy Colcannon (Irish Mashed Potatoes)

Jump to recipe

In almost every local Irish Pub that I have been in, and not going to lie, there have been several, you will see some version of potatoes (yes, the Irish staple).  One of my favorite mash ups, if you will, yes…pun intended and well placed…is Colcannon.  Now if you have never had Colcannon you need to make some tonight. 

If you have left over cabbage and want to make this tommorow, well then this is going to be a cinch! Either way it’s a breeze!


Colcannon is an Irish dish containing mashed potatoes with a ton of cream and butter, along with either cabbage, or kale, and chopped green onions.  How can this be a bad thing?  The savory combination of the greens gives this such a luscious, buttery taste which I simply adore, and full disclosure, I am not a huge fan of mashed potatoes, gasp…..huh?  I know, I know, hard to believe, but I never have been, but I do truly adore this dish, oh soo much!!!


You can certainly use leftover mashed potatoes and cabbage to pull this together, but I absolutely love using baby kale, it’s perfect for this and sautés in no time. 

If you are using leftovers, you can adapt this recipe accordingly.  If starting from scratch, simply follow your favorite mashed potato recipe, and sauté your greens in a little butter and oil, then prepare according to directions below.  It couldn’t be simpler to make Classy Colcannon.


Like with any recipe, liberties can be taken to make it uniquely your own, which by the way yours truly and most foodies do!  Good substitute for greens are, spinach and swiss chard.  You can also add chives in place of the green onions or use leeks to create a milder onion profile. 

One note: If you are making this and want to get a true Irish feel for this dish, make the Classy Colcannon with full fat cream as in heavy cream and butter, no matter how you vary the other ingredients. 

It does make a huge difference in the overall integrity and richness of the dish.

Also, let me just add that if you have a potato ricer, and I hope you all do, I suggest using it, mashed potatoes are not mashed potatoes in my opinion, until you use a ricer, trust me on this!

This is such a simple but classy recipe, and one which is a true Irish classic.  I hope you give this a try today.  You will not be sorry!

Happy St. Patrick’s Day, from our home to yours!💚🍀
