Kale Colcannon – The Irish Mashed Potato Side That’s Cheap, Green, and Perfectly Creamy
Colcannon is one of those dishes that sounds humble – mashed potatoes mixed with greens – yet somehow manages to be greater than the sum of its parts. The Irish have known this for centuries. Now, with kale standing in for the traditional cabbage, this version is greener, more nutrient‑dense, and just as comforting. It costs sixty cents a serving, comes together in 45 minutes, and has already won over the few home cooks who have discovered it. A 76% spoonacular score is nice, but the real evidence is on the plate.
“I made this for a St. Patrick’s Day dinner and my kids – who usually run from anything green – asked for seconds. It’s creamy, buttery, and the kale softens just enough to blend in without disappearing.”
What Is Colcannon, Anyway?
Colcannon is Ireland’s answer to mashed potatoes, elevated. The name comes from the Gaelic cál ceannann, meaning “white‑headed cabbage.” Traditionally, it is a simple mixture of mashed potatoes, butter, milk, and shredded cabbage or kale, seasoned with salt and pepper and sometimes studded with scallions. It was once a Halloween staple – fortunes were hidden inside: a ring for marriage, a thimble for spinsterhood, a coin for wealth.
This version swaps in kale, which holds its texture a bit better than cabbage and brings a slightly earthy, peppery note. It is still unmistakably colcannon: creamy, buttery, and studded with tender ribbons of green. Each serving delivers 289 calories, 6 grams of protein, and a generous 22% of your daily vitamins and minerals – mostly from the kale’s impressive haul of A, C, and K. At $0.60 per plate, it is also one of the most affordable ways to get those nutrients.

Ingredient Notes
Potatoes. Yukon Golds strike the perfect balance – they are buttery and creamy without becoming gluey. Russets work too; just take care not to overwork them, or you will end up with wallpaper paste.
Kale. Curly kale is traditional, but Lacinato (dinosaur) kale is also excellent. Remove the tough ribs before slicing. The finer you slice the leaves, the more evenly they will integrate into the potatoes.
Butter and milk. This is a potato dish; do not skimp on the dairy. Whole milk and good salted butter make it silky. For extra richness, swap in heavy cream.
How to Make Kale Colcannon (Step by Step)
1. Cook the Potatoes
Place the potato chunks in a large pot and cover with cold water by an inch. Add 1 teaspoon of salt. Bring to a boil, then reduce heat and simmer until the potatoes are fork‑tender, 12 to 15 minutes. Drain well and return the potatoes to the hot pot to steam off excess moisture for a minute or two.
2. Wilt the Kale
While the potatoes cook, melt 1 tablespoon of butter in a large skillet over medium heat. Add the sliced kale and a pinch of salt. Cook, tossing frequently, until the kale is wilted and tender, about 5 minutes. If you like it softer, add a splash of water and cover for another 2 minutes. Set aside.
3. Mash and Combine
Warm the milk and remaining 3 tablespoons of butter together (microwave or stovetop). Pass the potatoes through a ricer for the smoothest texture, or mash them by hand in the pot. Gently stir in the warm milk‑butter mixture, then fold in the wilted kale and scallions. Season with pepper and additional salt to taste.
4. Serve
Spoon the colcannon into a warm serving bowl. Make a well in the center and add a generous pat of butter. Sprinkle with a few extra scallion greens and a crack of black pepper. Serve hot.
🥔 Pro Tips for Perfect Colcannon
- Dry your potatoes. After draining, let them sit in the pot over low heat for a minute – steam equals water, and water dilutes creaminess.
- Don’t overmix. Stirring too vigorously activates gluten and turns your silky mash into paste. Fold gently.
- Warm your dairy. Cold milk or butter will seize up the potatoes. Always add warm liquid.
- Make it ahead. Colcannon can be made a day in advance and reheated in a double boiler or microwave with a splash of milk.
Serving Suggestions
Kale colcannon is a shape‑shifter of a side dish. It is the traditional partner for corned beef and bangers (Irish sausages), but it also works beautifully with:
- Roast chicken or turkey – Especially with pan gravy.
- Grilled salmon – The richness stands up to oily fish.
- Meatloaf – A cozy, retro pairing.
- As a bed for fried eggs – Spoon it onto a plate, top with a runny‑yolk egg, and breakfast is served.
Variations to Keep It Interesting
Once you master the classic, try these simple twists:
- Cabbage Colcannon: Substitute ½ head of green cabbage, shredded, for the kale. Sauté until tender and slightly caramelized.
- Vegan Colcannon: Use plant butter and unsweetened oat milk. Nutritional yeast stirred in at the end adds a cheesy note.
- Cheesy Colcannon: Fold in ½ cup grated sharp cheddar after mashing. Let it melt into the hot potatoes.
- Champ: The Northern Irish cousin – same creamy mash, but with scallions or chives folded in and no greens. Also excellent.
Storage and Leftovers
Colcannon keeps well in the refrigerator for up to 4 days. Press a piece of plastic wrap directly onto the surface before sealing the container – this prevents a skin from forming. To reheat, warm gently in a saucepan with a splash of milk, or microwave in short bursts, stirring between. Leftover colcannon can also be shaped into patties and pan‑fried in butter until golden on both sides. Some might argue these fried cakes are even better than the original.
The 76% Spoonacular Score – What It Means
This recipe holds a spoonacular score of 76%, which the platform considers “solid.” The algorithm takes into account cost, nutrition, and user feedback. With a per‑serving cost that barely registers and a nutrient profile boosted by kale’s vitamin density, it is easy to see why the numbers are favorable. The small sample size – two impressed home cooks – is enough to suggest that this dish has staying power. Seventy‑six percent is a quiet vote of confidence from a system that is notoriously hard to please.
🍀 The Final Verdict
Kale colcannon will never be the flashiest dish on the table. It is beige and green, humble and straightforward. But one spoonful, especially alongside a hunk of roasted meat or a slick of melting butter, and you will understand why the Irish have been making it for centuries. It is comfort food stripped to its essentials: potatoes, butter, greens, and salt. At sixty cents a serving, you can afford to make it a regular habit.
