How To Make Authentic Traditional Irish Colcannon

Colcannon is a classic Irish dish made primarily from mashed potatoes, cabbage (or kale), butter, and cream.

The name “Colcannon” is derived from the Gaelic words *cal ceannann*, meaning "white-headed cabbage." Traditionally served during Halloween, colcannon was often used in fortune-telling rituals, with coins or charms hidden inside to predict the future of the lucky diner who found them.

Ingredients for Authentic Irish Colcannon

• Potatoes (4 large, preferably a starchy variety like Russet or Yukon Gold)
• Cabbage or Kale (2 cups, finely chopped)
• Butter (4 tablespoons, unsalted)
• Milk or Cream (1/2 cup)
• Green Onions or Leeks (1/2 cup, finely sliced)
• Salt and Pepper (to taste)

Step-by-Step Recipe for Irish Colcannon

Step 1: Boil the Potatoes

1. Peel the potatoes and cut them into evenly sized chunks for quicker cooking.
2. Place the potatoes in a large pot, cover with cold water, and add a pinch of salt.
3. Bring the water to a boil and let the potatoes cook for 15-20 minutes, or until they are fork-tender.

Step 2: Prepare the Greens

1. While the potatoes are boiling, heat 2 tablespoons of butter in a medium saucepan over medium heat.
2. Add the finely chopped cabbage or kale and sauté until softened (about 5-7 minutes).
3. Stir in the green onions or leeks and cook for an additional 2 minutes.

Step 3: Mash the Potatoes

1. Drain the boiled potatoes and return them to the pot.
2. Add 2 tablespoons of butter and mash the potatoes until smooth. For an extra creamy texture, use a potato ricer.
3. Gradually stir in the milk or cream until the desired consistency is reached.

Step 4: Combine and Season

1. Fold the sautéed greens into the mashed potatoes using a wooden spoon.
2. Season with salt and pepper to taste, mixing well to ensure even distribution.
3. Optional: Add an extra dollop of butter on top for a traditional touch.

Step 5: Serve and Enjoy

Serve the colcannon hot, either as a standalone dish or as a side to corned beef, sausages, or roasted meats. For authenticity, create a small well in the center of the colcannon and let a knob of butter melt into it before serving.

Tips for the Perfect Colcannon

• Choose the Right Potatoes. Starchy potatoes like Russets or Yukon Golds yield the best creamy texture.
• Experiment with Greens. While cabbage is traditional, kale adds a modern twist with its earthy flavor.
• Don’t Skimp on Butter. The rich, buttery flavor is key to an authentic Irish colcannon.
• Make it Ahead. Prepare colcannon in advance and reheat gently, adding a splash of milk to maintain its creamy consistency.

Variations of Colcannon

• Vegan Colcannon. Swap butter for vegan margarine and use plant-based milk for a dairy-free version.
• Cheesy Colcannon. Mix in grated cheddar for an indulgent twist.
• Bacon Colcannon. Stir in crispy bacon bits for added flavor and crunch.
• Sweet Potato Colcannon. Substitute regular potatoes with sweet potatoes for a healthier, sweeter alternative.
