What Kind of Potatoes Work Best for Colcannon?

For ultra-creamy colcannon, you’ll want to use floury potatoes like Russets or Yukon Golds. They mash smoothly and absorb the butter and cream beautifully. Avoid waxy potatoes like red or new potatoes—they tend to stay a bit too firm and don’t give you that fluffy finish that makes colcannon so irresistible.

Ingredients for the Traditional Irish Colcannon

Potatoes – The base of the dish. Go with Yukon Golds or Russets for a creamy, fluffy mash.

Cabbage or Kale – A traditional green used in colcannon. Adds a mild, earthy flavor and slight crunch. Kale offers a bolder taste.

Butter – Richness is key. Don’t skimp! Salted butter enhances every bite.

Heavy Cream or Milk – Cream makes it luxurious, but milk works too for a lighter version.

Green Onions (Scallions) – Brings a sharp, bright note that balances the richness.

Salt and Pepper – Essential seasonings to elevate all the ingredients.

Optional: Garlic – Adds a mellow, savory depth if you want extra flavor.

How To Make the Traditional Irish Colcannon

Step 1: Boil the Potatoes

Peel and cube the potatoes, then place them in a large pot with salted water. Bring to a boil and cook until fork-tender, about 15–20 minutes.

Step 2: Sauté the Greens

While the potatoes are cooking, melt some butter in a large skillet over medium heat. Add chopped cabbage (or kale) and cook until tender, about 5–7 minutes. If you’re using garlic, add it in the last minute to avoid burning.

Step 3: Warm the Dairy

In a small saucepan, gently heat the heavy cream or milk with a couple tablespoons of butter. You want it warm—not boiling—so it incorporates smoothly into the mash.

Step 4: Mash the Potatoes

Drain the cooked potatoes well and return them to the pot. Mash until smooth using a potato masher or ricer.

Step 5: Combine Everything

Add the warm cream mixture to the mashed potatoes and stir until creamy. Fold in the sautéed greens and chopped green onions. Season with salt and pepper to taste.

Step 6: Finish with Butter

Serve warm with a generous knob of butter on top. Let it melt into the mash—it’s the traditional way!

How to Serve and Store Traditional Irish Colcannon

Colcannon is best served piping hot, straight out of the pot, with a big spoonful of butter on top. It’s an ideal side for corned beef, roasted chicken, sausages, or even baked ham. Some even enjoy it as a main meal with a fried egg or leftover roast on top.

If you have leftovers, transfer them to an airtight container and refrigerate for up to 3 days. Reheat gently in a pot over low heat with a splash of milk or cream to bring back its creamy texture. You can also reheat it in the microwave, covered, stirring halfway through.

Frequently Asked Questions

What does “colcannon” mean?

“Colcannon” comes from the Gaelic term cal ceannann, which means “white-headed cabbage.” It reflects the traditional use of cabbage in the dish.

Can I make colcannon ahead of time?

Yes! You can make it a day in advance and reheat it with a bit of added cream or milk. It’s just as delicious the next day.

Is colcannon gluten-free?

It is naturally gluten-free, as long as you don’t add any thickening agents or gluten-containing ingredients.

Can I use other greens instead of cabbage or kale?

Definitely. Try Swiss chard, spinach, or even beet greens. Just sauté them until tender.

How can I make it vegan?

Swap the butter for a plant-based version and use unsweetened almond milk or oat milk instead of cream. It’ll still be rich and flavorful.

Does colcannon freeze well?

Mashed potatoes don’t always freeze with the best texture, but colcannon can be frozen in small portions. Reheat slowly and stir well.
