A recipe for Colcannon (Irish Mashed Potatoes)! Mashed potatoes are combined with greens and scallions for quite the delicious side.

Colcannon is an Irish dish traditionally made from mashed potatoes and kale (or cabbage). It is such a delicious and easy way to use up leftover greens and/or potatoes!
The dish may optionally also contain scallions (which I added), leeks, chives, or other types of onion. Simply boil the potatoes until tender, then peel and mash with the sautéed greens, milk, salt, and pepper.
Transfer the still hot mashed potatoes to a bowl and make a well in the center. Place an additional piece of butter in the well and allow it to melt.
I especially like this quote in The Irish Cookbook by Carla Blake. She states, “Serve in a hot dish, with the butter melting into a golden pool in a slight hollow in the centre, oozing across each helping as it is spooned to the waiting plates!”
In Ireland, Colcannon is especially popular around Halloween. Learn more about the Halloween traditions surrounding Colcannon from Irish American Mom.

A Few Colcannon Tips
I used kale in this recipe, but it can easily be swapped for finely shredded green cabbage. Some recipes boil the greens instead of sautéing them. If boiling, simply mix the 4 tablespoons (60 grams) butter into the potatoes with the milk.
Make sure the potatoes are boiled until completely tender, then mash them with a hand masher. Do not use a food processor. This will cause a more whipped, gummy texture.
I kept the finely chopped scallions raw and simply mixed them into the potatoes. If desired, you can cook them for 1-2 minutes with the kale until lightly softened.
Heat the milk before adding to the potatoes. This will help with the texture and keep everything hot enough to melt the extra butter when serving.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
