One of my St. Patrick’s Day’s favorites, Colcannon is Ireland’s best-known potato side dish. My version features creamy mashed potatoes, leeks, kale and bacon. Simple but so flavorful!
An easy Colcannon Recipe for St Patrick’s Day!
“Did you ever eat colcannon when ’twas made with yellow cream,
And the kale and praties blended like the picture in a dream?
Did you ever take a forkful, and dip it in the lake
Of the heather-flavoured butter that your mother used to make?”
The Irish love this dish so much, that – as you can see above – songs were written about it.
Can you blame them? Buttery potatoes, kale and bacon? Well, okay, the bacon is not often included, but I couldn’t resist it.
Few are the dishes that won’t benefit from a touch of salty, smoky bacon! Colcannon is not one of them. So do yourself a favor and add the bacon! You won’t be sorry.
And while this is the perfect side dish for a Paddy’s Day celebration, it is delicious year round. Whenever you need a side dish with character, remember of Colcannon! It is mashed potatoes on steroids.
Did you know?
If you’re going to shorten St Patrick’s Day, the right diminutive is Paddy and not Patty. Patty is short for Patricia, while Paddy is short for Pádraig (which is Patrick in Irish).
What is Colcannon?
Colcannon – pronounced kowl·ka·nuhn – is an authentic Irish dish consisting of mashed potatoes mixed with kale or cabbage.
The word comes from the Gaelic term “cal ceannann“, which means “white-headed cabbage”.
Despite the name, the dish can be made with either cabbage or kale, and sometimes a mix of both! Other ingredients such as leeks, scallions, onions and/or chives can also be added.
And while here in the US we associate colcannon with St. Patrick’s Day, in Ireland it is a Halloween tradition to serve it, with charms (like rings, coins, buttons and thimbles) hidden inside the dish.
Whatever you find, predicts your future. A ring means you will get married, a thimble means you will remain a spinster and a coin means you will get rich!
Some women would even go the extra mile and fill their socks with colcannon, hanging them from the handle of the front door. They believed that the first man through the door would become their future husband.
Despite all the fun and superstition, colcannon is not only reserved for Halloween, being a popular side dish year round in Ireland!
What is the difference between Colcannon and Champ?
While they are both Irish mashed potato dishes, Champ – popular in Northern Ireland – is slightly different, made of scallions mixed with mashed potatoes and no cabbage/kale.
WHAT YOU’LL NEED TO BUY:
- 2 1/2 pounds potatoes
- 1 leek
- 1 bunch lancinato kale
- 3 scallions
- 1 package thick-cut bacon
- Half a pint heavy cream
- 2.5 ounces unsalted butter
Ingredients I’m assuming you already have in your pantry. But, if not, make sure to buy them as well!
- Freshly ground black pepper
What are the best kind of potatoes for Colcannon?
For the fluffiest and creamiest mashed potatoes, choose higher starch potatoes, like Russets.
Yukon Golds, considered all-purpose potatoes, are medium starch and will work as well, but won’t get as fluffy as Russets do.
How to make Colcannon Potatoes
This is a simple and straight-forward colcannon recipe.
Cook the potatoes, cook the greens, mash the potatoes, add the greens, add the cream and bacon, and voila! You simply can’t mess this up.
Here’s how I make colcannon potatoes. As always, you will find the printable (and more complete) version of the recipe at the end of this post!
- Cook the potatoes in salted water.
- Cook the bacon. Reserve.
- Sauté the leek and scallions in the bacon grease.
- Add the kale and cook until wilted.
- Drain potatoes and place back in pot or in a large bowl.
- Mash the potatoes.
- Add the sautéed greens and continue mashing until incorporated.
- Add the heavy cream, butter and reserved bacon.
- Mix until smooth. Season. Serve!
- Don’t be shy with the butter! When ready to serve, while the Colcannon is still hot, make a little indentation in the middle and add several tablespoons of good quality butter. The butter will melt and drip all over the potatoes! Yum!
How to reheat leftovers
Colcannon potatoes will keep in the fridge for 3-4 days.
To reheat, place it in a saucepan and reheat on the stovetop, over medium-low heat. Stir often, adding a few splashes of heavy cream (or milk), to add back some moisture and restore its creamy and smooth texture.
Can I freeze it?
If you followed my cooking journey long enough, you’ve probably seen me write “DO NOT FREEZE POTATOES” more than once.
Well, this time it’s different.
While potatoes don’t freeze well, mashed potatoes do. As long as they are cooked with plenty of fat – and in this case we are using both cream and butter -, they will freeze without major alterations.
Just be prepared to add some extra dairy when reheating. You can reheat them straight from frozen, on the stove!
What to serve with Colcannon?
Colcannon is traditionally served with boiled ham or Irish bacon.
- 2 ½ pounds Russet potatoes, peeled and quartered
- Kosher salt
- 5 thick-cut bacon slices, diced
- 1 leek, rinsed and sliced
- 1 bunch kale, rinsed, stems removed and chopped
- 1 cup heavy cream
- 3 Scallions, chopped
- Freshly ground black pepper
- 5 tablespoons unsalted butter
- Place the potatoes in a large saucepan and cover with water. Season the water generously with salt. Bring to a boil and cook until the potatoes are tender, about 20 minutes. Drain well in a colander and place in a large bowl.
- While the potatoes are cooking, heat a Dutch oven over medium heat and add the bacon. Cook until golden brown. Using a slotted spoon, remove and place in a paper towel-lined plate. Reserve.
- Drain most of the rendered fat from the pot, leaving only a couple tablespoons in the pot. Add the leeks and scallions, and sauté until softened, about 5 minutes.
- Add the kale and cook until wilted, about 2-3 minutes.
- Mash the potatoes with 3 tablespoons butter, using a potato masher. Then, add the greens and continue mashing until smooth.
- Stir the heavy cream and bacon, and season with salt and pepper.
- Garnish with the remaining butter and some scallions.
- Serve immediately!
- Kale: You can substitute it for savoy cabbage or Swiss chard.
- Bacon: You can omit the bacon if you prefer.
- Heavy Cream: Half and half or whole milk can be used instead.
