Irish Colcannon is a beloved comfort classic that brings together creamy mashed potatoes with tender sautéed kale and fresh scallions. This vegetarian side dish is naturally gluten-free and comes together in just 45 minutes, making it ideal for weeknight dinners or special occasion tables.

The preparation is straightforward: boil russet or Yukon Gold potatoes until tender, blanch fresh kale briefly, then fold everything together with warm milk and butter for a silky, flavorful finish. A touch of salt and pepper brings out the natural earthiness of the ingredients, while the final garnish of scallions and butter adds brightness and richness.

The steam rises from the pot as I mash the potatoes for colcannon on a drizzly autumn evening, my kitchen windows foggy with condensation. I discovered this Irish classic years ago when trying to find more interesting ways to serve potatoes with our Sunday roasts. Something about the bright green kale ribbons folded into creamy potatoes feels both homey and special at once.

Last St. Patricks Day, I served colcannon instead of plain mashed potatoes with our corned beef, and my father-in-law who claims to hate all green vegetables asked for seconds. The kitchen filled with laughter when he realized hed been enthusiastically devouring kale all evening. Sometimes the best way to introduce someone to a new vegetable is to tuck it into something familiar and comforting.

Ingredients

  • Russet or Yukon Gold potatoes: Yukon Golds are my preference for their naturally buttery flavor, but I learned the hard way that russets will give you a fluffier result if thats your preference.
  • Kale: Remove those tough stems completely or youll end up with stringy bits that ruin the creamy texture weve worked so hard to achieve.
  • Scallions: The mild onion flavor here is traditional, but Ive discovered they must be sliced thin to distribute their flavor without overwhelming.
  • Whole milk and butter: This is not the place for skim milk the richness of whole milk creates that silky texture that makes colcannon so memorable.

Instructions

Prepare the potatoes:
Start with cold, generously salted water covering your potato chunks this helps them cook evenly from the inside out. Youll know theyre done when a fork slides in easily with no resistance.
Cook the kale:
Boiling the kale separately might seem like an extra step, but trust me, it ensures the perfect texture. Give those greens a good squeeze after draining they hold onto water like a sponge.
Warm the dairy:
Heating the milk and butter together is my favorite kitchen secret for silky mashed potatoes. Cold milk shocking hot potatoes can make them gluey a lesson I learned the hard way.
Mash with purpose:
Work quickly while the potatoes are still steaming hot for the smoothest texture. I like to mash in a rhythmic motion, turning the pot as I go to catch every piece.
Fold in the greens:
Use a gentle hand when incorporating the kale and scallions you want distinct ribbons of green throughout, not a uniform mixture. Save some scallions for the top for that perfect pop of color.
Finish with flair:
The traditional well in the center for extra butter isnt just for show its where the magic happens. That melting butter creates the most delicious sauce as you eat.

I still remember serving colcannon at our first dinner party in our new home, placing the steaming bowl in the center of the table as rain pattered against the windows. The conversation quieted momentarily as everyone took their first bites, then someone said, This isnt just a side dish, its the star of the meal. Sometimes the simplest foods, prepared with care, create the most lasting memories around a table.

Make-Ahead Options

Colcannon reheats beautifully, something I discovered by happy accident when guests arrived an hour late. Cover and refrigerate for up to two days, then warm in a 350°F oven with a splash of extra milk to bring back the creamy texture. The flavors actually deepen overnight, with the kale and scallions mellowing into the potatoes.

Seasonal Variations

Summer colcannon welcomes tender swiss chard or spinach in place of kale, creating a lighter version that pairs beautifully with grilled fish. Winter calls for hearty additions like caramelized onions or roasted garlic, turning this side into a meal that can stand on its own with just a fried egg on top. The versatility of this dish continues to surprise me even after making it dozens of times.

Serving Suggestions

While traditionally served alongside ham or bacon, my vegetarian friends go wild for colcannon paired with roasted mushrooms in garlic butter. The earthy flavors complement each other in a way that makes meat an afterthought rather than a necessity.

  • For a complete Irish feast, serve colcannon with Irish stew or corned beef and a pint of Guinness.
  • Leftover colcannon forms the base of incredible potato pancakes just form patties and pan-fry until golden.
  • For a casual brunch, top reheated colcannon with poached eggs and a sprinkle of sharp cheddar.

Recipe FAQs

Yes, you can prepare it several hours in advance and reheat gently over low heat with a splash of milk, stirring occasionally to maintain creaminess. Store in an airtight container in the refrigerator for up to 3 days.

Russet or Yukon Gold potatoes are ideal. Russets are starchier and create fluffier mash, while Yukon Golds are naturally buttery and rich. Avoid waxy potatoes as they don't mash as smoothly.

Frozen kale can work, but thaw and squeeze out excess moisture thoroughly before adding to prevent a watery dish. Fresh kale provides better texture and flavor for this traditional preparation.

Simply substitute plant-based milk and vegan butter in equal amounts. The dish remains creamy and delicious while maintaining its authentic character and serving as an excellent accompaniment to plant-based mains.

This side shines alongside roasted meats, grilled sausages, and hearty stews. It also complements roasted vegetables and can serve as a filling component in vegetarian meals.

Overmixing or using too much liquid can cause this texture. Mash potatoes gently until just smooth, add milk gradually, and ensure kale is well-drained. Use a folding motion rather than aggressive stirring when combining ingredients.
