Why You’ll Love This Traditional Irish Colcannon

This dish is budget-friendly, incredibly filling, and easy to make with pantry staples. The combination of fluffy mashed potatoes with garlicky greens makes it both nourishing and nostalgic. Plus, it’s naturally gluten-free and can be customized with your favorite herbs or even crispy bacon for extra indulgence.


What Kind of Potatoes Are Best for Colcannon?

Floury potatoes like Russet or Yukon Gold work best because they mash beautifully and soak up butter and cream like a dream. If you prefer a slightly chunkier texture, feel free to mash them less thoroughly for more rustic appeal.


Ingredients for the Traditional Irish Colcannon

  • Potatoes: The heart of the dish. Choose starchy varieties for that perfect creamy consistency.
  • Green Cabbage or Kale: Adds a lovely pop of color and earthy flavor. Kale offers a slightly more robust texture, while cabbage gives a sweeter bite.
  • Butter: Essential for creaminess and flavor. Use good-quality butter for best results.
  • Whole Milk or Cream: Helps loosen the mash and add richness.
  • Green Onions (Scallions): These give the dish a fresh, mild onion note that balances the richness.
  • Salt & Pepper: To bring out the natural flavors.

How To Make the Traditional Irish Colcannon

Step 1: Cook the Potatoes

Peel and cut 2 pounds of potatoes into chunks. Place them in a large pot, cover with cold water, and add a pinch of salt. Bring to a boil and cook for 15-20 minutes or until fork-tender. Drain well.

Step 2: Cook the Greens

While the potatoes are boiling, melt 2 tablespoons of butter in a skillet over medium heat. Add 2 cups of chopped cabbage or kale and sauté for 5-6 minutes, until tender but still bright. Stir in 4 chopped green onions and cook for another minute. Set aside.

Step 3: Mash the Potatoes

Return the drained potatoes to the pot. Add 4 tablespoons of butter and mash until smooth. Slowly stir in ½ cup of warm whole milk (or cream) until the mash reaches your desired consistency.

Step 4: Combine Everything

Fold in the sautéed greens and scallions. Season with salt and pepper to taste. Mix well and serve hot with an extra pat of butter on top.


How to Serve Irish Colcannon

Colcannon serves as a versatile side dish or even a vegetarian main. It pairs beautifully with roasted meats, sausages, or even fried eggs on top. This recipe yields about 4 cups, enough to feed 4 to 6 people as a side.


How to Store Irish Colcannon

Leftovers can be refrigerated in an airtight container for up to 4 days. To reheat, warm gently in a skillet with a splash of milk to restore its creamy texture. You can also freeze Colcannon for up to 2 months. Just thaw overnight in the fridge and reheat as needed.


Frequently Asked Questions

1. Can I make Colcannon ahead of time?
Yes! Prepare it up to 2 days in advance, store in the fridge, and reheat with a splash of milk or cream.

2. What’s the difference between Colcannon and Champ?
Champ is a similar Irish mash but uses only scallions and no greens like cabbage or kale. Colcannon includes the leafy veg.

3. Can I use plant-based milk or butter?
Absolutely. Oat milk and vegan butter work great if you’re making it dairy-free.

4. Why is my Colcannon gluey?
This usually happens if the potatoes are overworked. Use a potato masher instead of a mixer for the best texture.

5. What else can I mix in?
Crispy bacon, roasted garlic, or a sprinkle of nutmeg can elevate the flavor beautifully.
