Fluffy mashed potatoes with sauteed cabbage and bacon add up to Colcannon – a side dish that everyone loves for pretty much any occasion! This Colcannon Recipe is the ultimate in mashed potato dishes.
This traditional Irish and Scottish food combines mashed potatoes with cabbage or kale and occasionally bacon for a creamy savory side dish that was an instant hit in my family when I first made it almost ten years ago.

We tried Colcannon for the first time a few years ago, and served it alongside our Baked Honey Mustard Corned Beef. These potatoes were the biggest surprise hit that I made that year.
Most of my family enjoys bacon, cabbage, and mashed potatoes on their own, so their enthusiasm for this Colcannon recipe should have come as no surprise. Still, I had no clue that each member of the family would declare this dish awesome and eat every single spoonful.
Even my boys, who were extremely leery of the “green stuff” in their potatoes requested seconds and kept talking about how delicious the “ko-cannon” and corned beef dinner was. All three of them requested this again the next day for lunch and they were very disappointed that there was not anything leftover.
Colcannon Potatoes
Colcannon originates from Ireland where it became popular as a filling, inexpensive and tasty food to serve year round.
The dish found its way to Scotland where it’s also sometimes known as “Rumdlethumps”. Can you say that word without smiling? I definitely can’t.
Whatever you call it, this easy combination of comforting mashed potatoes, leafy greens and cream has won our American hearts and stomachs.
What is Colcannon?
At its most essential, the colcannon recipe is mashed potatoes mixed with chopped cabbage or kale. Other additions like bacon, ham, scallions or yellow onions are also common.
My preferred Colcannon recipe starts with a simple mashed potato recipe. Peeled chopped potatoes are boiled, then mashed over low heat with butter and milk.

How To Make Colcannon
I prefer red potatoes in this recipe; the starch and moisture ratio makes them perfect for mashing. You can also use white or Yukon gold potatoes if you prefer but steer clear of Russets (also known as baking potatoes). They tend to be crumbly and waxy when mashed and the texture won’t be quite right.
Crisp bacon, lightly cooked cabbage and browned yellow onions are added to the finished mashed potatoes to create a hearty and satisfying dish. We often lean into the Irish theme by eating it alongside corned beef or ham.
In all, honesty, though I think Colcannon could be treated as a meal in and of itself. After all, it includes meat, starch, and vegetables all in one dish!
Double the recipe and everyone at the table will be thrilled to dig into a big bowl of fluffy mashed potatoes, smoky bacon, and flavorful cabbage.

St. Patrick’s Day Recipes
Irish or not, St. Patrick’s Day is a prime opportunity to create a Celtic feast. If you’re looking to expand your St. Paddy’s repertoire beyond dyed green beer and shamrock shakes, I have a TON of delicious, easy yet somewhat more authentically Irish, recipes to share with you.
When it comes to Corned Beef for your Irish celebrations, it’s hard to go wrong with a traditional Corned Beef and Cabbage Stew. For a fun spin on tradition, give this tasty Baked Honey Mustard Corned Beef a try. It’s by far the best baked corned beef recipe I’ve made and delicious enough to add to your year-round dinner rotation.
When I make corned beef I intentionally make too much just so I’ll have leftovers for Corned Beef, Cabbage and Red Potato Hash. It’s a hash so delicious that I sometimes find myself making corned beef for dinner just so I can make hash the next day.
Hosting a party? A crock of Irish Pub Cheese served with crackers or crusty bread (and maybe a pint or two of Guinness) will get your soiree started on the right foot.
When I think of favorite Irish recipes, my mind also leaps to Irish Raisin Soda Bread. I first discovered the recipe when visiting Belfast, Ireland and it’s been a favorite to serve for tea, breakfast or a snack ever since.
This Irish Dark and White Pudding looks like the perfect dessert to cap off a dinner celebrating the Emerald Isle.

Mashed Potato Recipes
If you enjoy these potato recipes and Colcannon potatoes, you might also enjoy our Cheesy Mashed Potatoes with Green Chile and Garlic Smashed Potatoes. We really can’t get enough of creamy, fluffy mashed potatoes around these parts and can you blame us?

Colcannon Recipe
- Place the potatoes in a pot, along with enough water to cover them. Add 2 teaspoons salt to the pot and bring to a boil. Simmer until the potatoes are fork tender, about 15-18 minutes.
- While the potatoes are boiling, cook the bacon in a skillet over medium high heat. When the bacon has browned and is slightly crisp, remove to a paper towel lined plate. Reserve about a tablespoon of the bacon grease and drain the rest. Leave the rest of the drippings in the skillet. Add the onions to the hot skillet with the bacon grease and saute over medium high heat for 1-2 minutes, until they are lightly browned. Add the cabbage and toss lightly while it sautes and wilts, about 5 minutes. Season generously with salt and pepper as it cooks.
- Drain and place the potatoes back in the hot pot. Place the pot back over the still-warm burner (or if your stove is gas, set the heat to the lowest setting). Mash the potatoes over very low heat and add the milk, 1/2 – 1 teaspoon salt and pepper. Fold in the cooked and crumbed bacon, cabbage, and onions. Transfer to a serving bowl, form a small well in the center and fill with the butter. Serve hot. Enjoy!
Colcannon can be stored in an airtight container in the fridge for several days. Reheat in the microwave or on the stove top with a little extra butter before serving hot.

Do you think it would still be good if I use Idaho potatoes? I’m making for a crowd and I don’t have enough reds to go around? What do you think?!
Absolutely. I’ve made this with all different kinds of potatoes.
Do you peel the red potatoes?
Absolutely wonderful. I spent three lovely weeks all over Ireland, and never came across this dish. I can’t wait to make it!
Slap your Momma good!
Be nice to Momma! That phrase always makes me laugh. I am glad you enjoyed the recipe.
I’m surprised that an Irish dish has napa cabbage. But it sounds wonderful, so I’ll give it a go.
Sus
I’m making this now
I hope you love it as much as we do!
Do you peel the redskins?
I do not, but you certainly can if you prefer them peeled.
Just one issue for me. This Scottish great gran was brought up knowing the similar Scottish dish as Rumbledethumps, not as you have it written in your article. It is, along with colcannon, delicious!
Thank you.
What a fun name for the dish, Helen! I’ve never heard of Rumbledethumps before but a quick search online tells me it’s the Scottish version of Colcannon. I love learning new facts like this about the foods that we love.
I can’t wait to make this tomorrow.it sounds delicious.I was taught to make this with boiled cubed russet potatoes.I never thought of mashing the potatoes.
I hope you love it as much as we do, Mary.
Made it last nite for St Patrick’s Day dinner party. It was a hit. Everyone had seconds. Will be making this real soon
I’m so glad you liked the colcannon, Frank.
I have made Colcannon a few times before but I have never seen it done with Napa Cabbage. I was very wary about that but decided to try it, even though my available selection were only larger yellowing cabbage. I am glad I did. This will be the new way that I make it because the water cooked out of Napa in a way that broke down the cabbage better than regular green cabbage. Better flavor AND texture.
I used Yukon Gold potatoes and boiled them whole WITH my simmering corned beef (along with large chunk carrots). Removed the corned beef and carrots and water before starting STEP 3.
Great recipe! Everything was perfect and happy I have leftovers.
I am so happy to hear that you loved it so much, Janine!
This is an excellent recipe. I read several different Colcannon recipes and this sounded the best. I used half and half instead of milk. I also used 1/2 red potatoes and 1/2 Yukon Gold for the best creamy potatoes. My neighbors loved it.
I’m so happy to hear that you love it, Mary!
Absolutely delicious!! Makes more than enough to feed my hungry crowd!! Always have loved cabbage – raw or cooked – potatoes and bacon not as much but the combo is AMAZING!!
Lots of useless fluff to make room for ads. Why did it take me 20 minutes to learn to “fold in cabbage, onions and bacon into mashed potatos?”
I’m so sorry to hear that it took you 20 minutes to read through this post! For future reference, there’s a super handy “jump to recipe” button at the top of every page. It will take you directly to the recipe card and you can skip all the tips and commentary on the recipe.
First time making this. Had it at a St Patrick potluck and loved it, so I had to make it
I’m so glad you like it, Catherine!
I loved this recipe! The flavors blend perfectly, and it’s a great comfort food.
I’m so happy to hear that you love it as much as we do!
I made this recipe for St. Paddy’s Day, and we loved it. I have Irish roots, so I am familiar with this recipe. I used green onions because I like them and I used Napa cabbage (I liked how it was softer than regular) and turkey bacon instead of regular bacon (we don’t eat pork) for less fat. Thank you for such a lovely recipe. 🙂
I’m so glad you liked the potatoes!
have been looking for this recipe since I read Circle of Friends! mentioned a lot there
will give s go! jo from johannesburg
I hope you enjoy the colcannon!
Since you can find corned beef and cabbage most anywhere around mid-March, I’m looking to serve something different but truly Irish. I make a mean colcannon for my family, but I want to increase the amount to serve 50 or so people at my American Legin Post. Any suggestions?
The recipe as written will serve 6 people. If you multiple by 10, you’ll have more than enough for 50 people. Sounds like a fun evening!
