Equipment You’ll Need

• Large pot or Dutch oven
• Colander
• Large skillet
• Potato masher or ricer
• Sharp knife
• Cutting board
• Measuring cups and spoons

Ingredients

• 2.5 lbs (about 1.2 kg) Russet or Yukon Gold potatoes, peeled and quartered
• 1 cup whole milk or heavy cream, warmed
• 1 stick (1/2 cup or 113g) unsalted butter, divided (preferably Irish butter)
• 1 small head of green cabbage (about 1 lb) or 1 bunch of kale (about 8 oz), finely shredded or chopped
• 1 bunch of scallions (green onions), thinly sliced (both white and green parts)
• 1.5 teaspoons kosher salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper, plus more to taste

Instructions

1. Place the peeled and quartered potatoes in a large pot and cover with cold, salted water by at least an inch. Bring to a boil over high heat.
2. Reduce the heat to medium and let the potatoes simmer for 15-20 minutes, or until they are fork-tender and easily pierced with a knife.
3. While the potatoes are boiling, prepare the greens. Melt 4 tablespoons (half the stick) of butter in a large skillet over medium heat.
4. Add the sliced scallions and cook for 1-2 minutes until they soften and become fragrant. Be careful not to brown them.
5. Add the shredded cabbage or kale to the skillet. Sauté for 5-7 minutes, stirring occasionally, until the greens are wilted and tender. If using cabbage, it may take a few minutes longer. Season with a pinch of salt and pepper, then remove from heat and set aside.
6. Once the potatoes are cooked, drain them thoroughly in a colander. Let them sit for a minute to allow any excess steam and moisture to evaporate. This is key to fluffy, not gummy, potatoes.
7. Return the dry potatoes to the hot pot and place it back on the stove over low heat for 1 minute to cook off any remaining moisture. Mash the potatoes using a potato masher or ricer until they are smooth.
8. Add the remaining 4 tablespoons of butter, the warmed milk or cream, 1.5 teaspoons of salt, and 1/2 teaspoon of black pepper to the mashed potatoes. Stir gently until the butter is melted and everything is well combined. Do not overmix.
9. Gently fold the cooked scallion and greens mixture into the mashed potatoes until evenly distributed.
10. Taste the colcannon and adjust the seasoning with more salt and pepper if needed.
11. To serve, transfer the colcannon to a warm serving bowl. Make a well in the center and add an extra pat of butter to melt into a golden pool. Serve immediately.

Expert Cooking Tips

• Choose the Right Potato: Starchy potatoes like Russets or all-purpose potatoes like Yukon Golds are essential. They break down beautifully, creating a light and fluffy texture. Avoid waxy potatoes (like red potatoes), which can become gluey when mashed.
• Warm Your Dairy: Adding cold milk or cream to hot potatoes can cool them down and result in a less smooth texture. Gently warm your milk or cream on the stovetop or in the microwave before incorporating.
• Don’t Overwork the Potatoes: Mash until just smooth. Over-mashing, especially with a food processor or electric mixer, breaks down the starch molecules and results in a gummy, unpleasant texture.
• The Butter Well: Serving colcannon with a ‘well’ of melted butter in the center is traditional and highly recommended. It allows each person to scoop a perfect bite of potato with a little extra richness.

Substitutions and Variations

For a vegan version, use a high-quality plant-based butter and an unsweetened, creamy plant-based milk like oat or soy milk. You can also experiment with other greens; Swiss chard or savoy cabbage are excellent alternatives to kale or green cabbage. For a smokier flavor, substitute leeks for the scallions.

Common Mistakes to Avoid

The most common mistake is using the wrong type of potato, leading to a waxy or dense final product. Another frequent error is not draining the potatoes well enough; waterlogged potatoes will be bland and mushy. Finally, under-seasoning is a major pitfall. Potatoes and cabbage require a generous amount of salt to bring out their flavors, so be sure to taste and adjust before serving.

Serving Suggestions

Colcannon is a versatile side dish that shines alongside classic Irish fare like corned beef and cabbage, bangers and mash (as a substitute for plain mash), or a hearty lamb stew. It’s also fantastic with roasted chicken, pan-seared pork chops, or a simple steak. For a satisfying vegetarian meal, serve a generous portion of colcannon topped with a perfectly fried egg.

Storage and Reheating Tips

Store leftover colcannon in an airtight container in the refrigerator for up to 4 days. To reheat, you can microwave it in 30-second intervals, stirring in between, or warm it in a saucepan over low heat with a splash of milk to restore its creamy consistency. Leftover colcannon also makes phenomenal fried potato cakes: simply form into patties, dredge lightly in flour, and pan-fry in butter until golden brown and crispy on both sides.

Frequently Asked Questions

What is the difference between Colcannon and Champ?

They are both traditional Irish mashed potato dishes, but the key difference lies in the greens. Colcannon is made with kale or cabbage, while Champ is made exclusively with chopped scallions (green onions) stirred into the mash.

Can I make Colcannon ahead of time?

Yes, you can make it a day in advance. Prepare the dish completely, let it cool, and store it in an airtight container in the refrigerator. Reheat it gently on the stovetop with a splash of milk or cream to loosen it up, or in a covered oven-safe dish at 350°F (175°C) for about 20-25 minutes until heated through.

Can I freeze Colcannon?

While you can freeze it, the texture of the potatoes may change slightly upon thawing, becoming a bit grainier. For best results, thaw it in the refrigerator overnight and reheat slowly on the stovetop, stirring in extra butter and milk to improve the consistency.
