This Colcannon recipe is the perfect St. Patrick’s Day dish (or any other day you’re craving true comfort food)!
Colcannon is a traditional Irish dish combining creamy mashed potatoes with sweet cabbage and fried onion. It’s the ultimate cozy side.
This dish is great served with corned beef or glazed honey ham.
What is Colcannon?
When we think of cabbage recipes we often go to cabbage rolls, coleslaw or fried cabbage but this Colcannon recipe will quickly become a favorite!
Colcannon is a traditional dish from Ireland made with fried cabbage and onion (or scallions or leeks) fried until tender and gently folded into rich and creamy mashed potatoes (I sometimes add a little bit of bacon too).
You can use kale instead of cabbage, but I personally prefer the softer and sweeter taste of cabbage. Colcannon is traditionally topped with melted butter – because let’s be honest, mashed potatoes and butter are a match made in heaven.
Ingredients
Potatoes – You’ll need a good starchy baking potato. Our favorite choices are Russet or Yukon gold potatoes. Once boiled, mash them with lots of butter, light or heavy cream. While it’s not traditional, you can also add sour cream or cream cheese to taste.
Cabbage – Green cabbage becomes tender and sweet when fried with butter. However, you can substitute curly kale (about 1lb) or savoy cabbage if you prefer.
Onion – Fried onions pair beautifully with mashed potatoes. Use a white onion, or green onion, or try using leeks for an extra special dish. Leeks are mildly flavored and look like extra large scallions.
Butter & bacon – Could anything be better?! I love the flavor bacon adds although it’s not a traditional addition. If I have it on hand, I add it but if I don’t this colcannon recipe is equally delicious with just butter.
How To Make Colcannon
To make homemade colcannon:
- Cook the potatoes in a large saucepan until fork-tender and drain well per the recipe below. Mash the potatoes with cream and butter.
- Soften onion or leeks and cabbage in a skillet.
- Taste and season with salt and black pepper. Stir the cabbage mixture into the mashed potatoes and top with lots of butter.
Garnish with a sprinkle of parsley, chives, and/or crisp bacon.
What To Do With Leftover Colcannon
Store Colcannon 4 days in an airtight container in the fridge in a container or covered. To reheat it, place it on the stovetop with a little cream to keep the consistency of the mashed potatoes.
Leftovers can be used to top shepherd’s pie or turned into crispy potato patties.

This recipe works great with Smashed Cauliflower for a lower fat rendition. A bit of cabbage types on cabbage, but awesome!
I sauté the onion and cabbage in a little bacon fat and WOW! Really makes the potatoes rich. My family requests these on a regular basis.
Can this be made ahead. If so what degree would you heat it and for how long. Thank you in advance.
Hi Elizabeth, you can make this dish ahead of time and when you’re ready to reheat, take it out of the fridge to sit at room temperature for about 30 minutes. Pop it in the oven at 350°F for 20-25 minutes (or until heated through), stirring at the halfway mark. Let us know how it goes for you!
My very first time making this was for my in-laws and hsbd and I this October. We all thoroughly enjoyed this side dish that I served with homemade cabbage rolls and roasted baby carrots. What a terrific use of scrap pieces of cabbage! I sautéed leeks with the cabbage and my russet potatoes were thickened with heavy cream, a dollop of cream cheese and plenty of real salted butter. My in-laws were VERY happy to keep all the leftovers to have the following morning with breakfast eggs! I’m currently making this again (today) to have with a pork roast. It’s my daughters turn to try this now… I will continue to make this delicious recipe, what a great find!!
So delicious, June! I am glad everyone enjoyed it so much.
I often change it to an entree by adding diced leftover corned beef…or browned hamburger…
I don’t see where I am supposed to add the cream?
Sorry for the confusion, the cream is added in step two to the mashed potatoes.
Great recipe! I had so much leftover cabbage from st Patrick day parades and got tired of the same recipes. I had leftover pot roast and I added it to the cabbage mix, put the mashed potatoes on top and topped it with some cheese I had lying around. I put it in the oven at 375 until all the cheese melted and the edges got slightly brown. kinda like shepherd’s pie. I know this is a huge deviation, but I never would have thought of it if I didn’t see this recipe!
Great recipes
Can’t wait to try it! New cabbage fan here (isn’t it funny how our tastes change…suddenly discovering I DO like cabbage at 57 years old!) Could I use red cabbage for this? Would there be a big taste difference?
I have not tried using red cabbage so I can’t say for sure but I think it would taste great Denise! If you try it be sure to let us know how it turns out!
Would radishes work in place of potatoes for a lower carb version? I’m diabetic.
We haven’t made this recipe with radishes but I don’t see why not, Rachael. I think that would work well.
Sorry I didn’t see the potato info until after I posted my question and didn’t know how to delete the question.
No worries, Lorraine! We hope you enjoyed the recipe :)
I am making this tomorrow. Just curious what type of potatoes you used?
As mentioned in the post Lorraine, our first choices are Russet potatoes or Yukon gold! Enjoy!
Amazing! Thanks for the great recipe!
I can’t believe I’ve never heard of this before.
Made it with cabbage rolls.
That was supposed to be five stars!
So happy that you loved it so much!
Have you ever tried using the potatoes and cabbage that cook with the Corned beef in your slow cooker recipe?
I haven’t, that sounds like a delicious idea! Let us know how it goes!
That’s the only way I make it – mash the potatoes (I make extra just for this dish) and fold in any leftover cabbage, then add the fresh fried cabbage and onions

Can you leave out the rice? No cauliflower rice either. Would it effect the taste too much?
This recipe does not contain rice Sharon.
I did the same thing. I clicked on the link from the Crockpot Cabbage Roll recipe, that did contain rice, to this recipe. Trying both!!
Can you freeze the left overs?
Ginny, I have never tried freezing this recipe
Hi, Ginny. As a general rule, potatoes do not freeze well. They become mealy, or chalky in texture.
