Oh you did, so you did, so did he and so did I. And the more I think about it, sure the nearer I’m to cry. Oh weren’t them the happy days when troubles we knew not, and our mothers made colcannon in the little skillet pot

Colcannon – traditional Irish song

It’s time for a superb side dish for a St. Patrick’s Day Corned Beef and Cabbage. Or an Irish Stew. Or, frankly, anything that goes with mashed potatoes, that could use the bonus of some kale and green onions mixed in.

(My kids are old enough now that they were at least willing to try these potatoes, even with the “green stuff” mixed in. And they were pleasantly surprised.)

These potatoes are similar to champ, another Irish mashed potato recipe, with the added bonus of kale mixed in. My mashed potato technique has changed since I made that champ recipe (holy cow – eight years ago? Where does the time go?) I get better results when I pressure steam the mashed potatoes in a vegetable rack over a cup of water. Also, I cook the potatoes and kale together, then separate them so I can mash the potatoes without breaking up the kale too much.

Looking for some traditional Irish potatoes and greens for your St. Patricks day dinner? Try Colcannon:

Instant Pot Colcannon (Irish Mashed Potatoes and Kale)

  • Author: Mike Vrobel
  • Prep Time: 15 minutes
  • Cook Time: 10 minutes
  • Total Time: 25 minutes
  • Yield: 6 cups of potatoes 1x


Instant Pot Colcannon, Irish mashed potatoes and Kale in a pressure cooker, with greens and scallions mingled like a picture in a dream…


  • 1 cup water
  • 2 pounds russet potatoes, peeled and cut into – to 2-inch chunks
  • 3 ounces of kale, stemmed and chopped (about 2 cups lightly packed chopped kale leaves)
  • 4 tablespoons butter
  • ½ teaspoon fine sea salt
  • 1 cup heavy cream (or half and half, or milk)
  • 2 scallions, minced
  • More minced scallions and butter for topping


  1. Pressure Cook for 7 minutes with a quick pressure release: Pour 1 cup of water into an Instant Pot or other pressure cooker. Add a vegetable steaming basket, then fill the basket with the potato chunks, and top with the chopped kale. Lock the lid and pressure cook at high pressure for 7 minutes in an electric pressure cooker or stovetop PC (Use “Manual” or “Pressure Cook” mode in an Instant Pot). When the cooking time is over, quick release the pressure. Once the pressure is released, unlock the pot, opening the lid away from you to avoid the hot steam.
  2. Melt butter and mash the potatoes: Carefully lift the steaming basket out of the pot, and set aside on a heatproof surface (I use a large plate). Pour the water out of the pot liner, put the pot liner back in to the pressure cooker base (or back on the stovetop), add the butter, and melt the butter over sauté mode (medium heat on the stovetop). While the butter is melting, separate the kale from the potatoes. Once the butter melts, turn off the heat, and add the potatoes. Sprinkle the potatoes with the salt, and give them a rough mash, stirring to coat with the butter and salt. Add the cream. Mash again, starting out gently – the cream will splatter – and keep mashing and stirring until the cream is blended in and the potatoes are smooth.
  3. Stir in the kale and scallions: Stir in kale and the minced scallions. Transfer to a serving bowl, sprinkle with a little more minced scallions, add a big pat of butter to the middle of the bowl, and serve.


If you don’t have a steamer basket, you can put the potatoes straight into the water, with the kale on top. They’ll come out a little mushier, but still mash up well.
