If you add kale to buttery mashed potatoes, that makes it healthy, right? Ha! You’ve gotta try this classic Irish mashed potatoes recipe called Colcannon.
A couple of years ago I was looking for some Irish recipes to make for St. Patrick’s Day when I stumbled on Colcannon.

What Is Colcannon?
Colcannon is Irish mashed potatoes made with milk and butter and mixed with cabbage (or kale) and green onions. It’s similar to another Irish dish, champ, which is mashed potatoes with just the green onions mixed in, but no other greens. I could go for that, a bit of green in my spuds.
How To Serve Colcannon
I read through some recipes and found something in a few of them that made me excited. It’s the way the recipes said to serve it. You scoop the mashed potatoes into serving bowls. Then you put an indentation into each mound of potatoes. Then you add a slice of cold butter to that indentation.
By the time the bowls of potatoes make it to the table, the butter has melted into a little yellow puddle. As you dip your fork into the mash each time, it will go through that puddle each time. Oh my god, right?
I just had to try it and I’m so glad that I did. Delicious! You are so going to love this one! Try serving it alongside a Corned Beef and Cabbage dish.
