Easy Irish Colcannon Recipe With Leftover Mashed Potatoes

March 11, 2025 By Jessica Leave a Comment

Jump to Recipe Print Recipe

St. Patrick’s Day is just around the corner so we’re celebrating at home with this Colcannon recipe – a traditional Irish pub staple. Serve with my Bangers and Mash and you’ve got yourself a marvelous meal.

Colcannon Recipe

Thanks to my Grandma June I have good percentage of Irish in my DNA (28% to be exact), so it’s no wonder on why I enjoy the culture’s food so much. The first time I had this dish was a cozy dinner with her, but sadly I do not have her exact recipe to share here (I do have her famous Bierocks, these Cheesy Potatoes / aka “Funeral Potatoes”, and her Home-Style Chicken Meatloaf on the blog though!), so this is my take on her version and I hope I’m making her proud!

COLCANNON RECIPE INGREDIENTS:

I absolutely love all the bright pops of green in this dish! Hello festive! Here’s everything you’ll need to prep this delicious dish at home:

  • Butter
  • Leek
  • Yellow Onion
  • Garlic Cloves
  • Lacinato Kale
  • Prepared Yukon Gold Mashed Potatoes
  • Cream Cheese
  • Green Onions
  • Italian Parsley
  • Salt + Pepper

POPULAR COLCANNON VARIATIONS:

Here are a couple ideas to make this recipe your own! 

POTATOES: I prefer Yukon gold for this recipe but russet or baby reds will also do the trick. Make sure to peel them!

CHEESE: While I like to add cream cheese (who doesn’t like cream cheese in their mashed potatoes?), but you could also swap that for shredded cheese. I think Gruyere, sharp cheddar, or Monterey Jack would pair nicely.

VEGGIES: This dish is made with either cabbage or kale. I like to use kale to make this more festive in color.

MEAT: I usually pair colcannon with sausages, so I like to keep this vegetarian. However, some recipes call for bacon so feel free to crumble that in if you’d like!

HERBS: I use parsley, but you could also add rosemary or thyme if that’s what you fancy.

NOTES ON THIS RECIPE:

  • Add about 30 minutes to the prep time if you want to make the mashed potatoes at the same time. Here’s my recipe for Ultimate Yukon Gold Mashed Potatoes.
  • The cream cheese isn’t 100% necessary, I just personally enjoy the extra creamy texture and flavor it adds.
  • Any leftovers should be kept in a sealed container, refrigerated, and enjoyed within the next 2 days.
