Slow Cooker Colcannon potatoes are the traditional Irish side dish of creamy buttery mashed potatoes with kale or cabbage cooked in a non-traditional way.  The perfect accompaniment for a St. Patrick's day feast.

Slow cooker colcannon potatoes are an easy take on the traditional Irish side dish of mashed potatoes with kale or cabbage. 

It's one of our favorite Irish recipes and a must have on the table every Saint Patrick's Day! 

I also make it an extra few times times a year because it goes with just about any comfort food. 

Colcannon is a tasty side with braised beef, roast chicken, pork roast, turkey, seafood, meatloaf, and (of course) corned beef.

Loaded with cream and butter, so it's rich and creamy and completely satisfying. 

A hearty, stick to your ribs, good drinking base kind of dish to see you through the drinking holiday.

Best potatoes for mashed potatoes

The best potatoes for mashing are ones that have a higher starch profile, like Yukon Golds or Russets.

Avoid waxy potatoes, like red or white varieties, that are better suited for roasting or to use in potato salads.

Yukons are fluffy, creamy, and have the perfect flavor for this recipe, plus they are my personal favorite!

For the greens in the colcannon, I like a mixture of cabbage and kale. 

I've seen it made with leeks, chives, and/or spring onions, so feel free to add any of those for some extra flavor.

Usually I cook Colcannon on the stove, but this year I adapted the recipe for the slow cooker. 

It's the perfect cooking method for all of you who will be spending Saint Patrick's day at work.

Or even if you decide to use up a sick day ("wink wink") and start at the pub a little early.

I usually make a double recipe of this colcannon, so I can have leftovers for a few days. 

It's wonderful topped with a little cheddar cheese and heated up in the microwave the next day for lunch.

Makes awesome potato pancakes for breakfast or dinner too!  

Complete your Irish menu with:

  • Irish Stout Lamb Stew
  • Irish Spotted Dog
  • Irish Coffee

    Yummy, Karrie! I've never had colcannon, but so love mashed potatoes, and with kale or cabbage, even more. Like the idea of using the slow cooker, easy breezy. And that pat of butter melting on top? Oh, my!!

    Girl, you know I've never met a potato I didn't like and these need to get in my belly! You are such a genius to make them in a slow cooker because then you can just come home, open a beer, and stuff your face! I absolutely need some of these and that pic with the melting butter is the money shot!

    I have never heard of traditional Irish side dish Colcannon. There is so much to learn. Love how beautifully you have combined creamy and slicky buttery mashed potatoes and leafy greens. This would indeed make a great accompaniment to St. Patrick’s day meal. Wonderful share, Karrie.

    You know I've never had 'colcannon' potatoes before? I mean I've Newfoundland Hash before where you basically throw leftovers from a traditional Sunday dinner around here in one pan and fry (like salt beef, cabbage, tatos and carrots), but never tatos and cabbage like that in mash form. Sounds like the perfect base if one would like to partake in any St. Patrick's Day celebrations.....hehehe. P.S. that shot with the butter on top of those tatos? Got me swooning, girl! This chicka loves her some butta - little tooooo much. And good suggestion of adding some onion to the mix XO

    I like to use different veggies for a mash, and this one sounds fantastic to me (I've never used cabbage in mash though). I'd like to have some of this with crumbled blue cheese. And have you tried additng cream cheese in mashed potatoes? This makes a lighter but still rich and delicious version.
