Colcannon is one of Ireland’s most beloved comfort foods — a simple but deeply satisfying dish made from creamy mashed potatoes folded together with tender cabbage or kale and sautéed onions or leeks. Traditionally served in Irish homes during the cooler months and especially on St. Patrick’s Day, colcannon celebrates humble ingredients prepared with care.
The dish dates back centuries, when potatoes and leafy greens were everyday staples in rural Irish kitchens. Butter and cream transform these simple ingredients into something rich and comforting. In Ireland, a small well of melted butter is often pooled in the center of the mashed potatoes so each bite can be dipped into it.
This version keeps the classic flavors while offering a few optional additions — including bacon or parsnips — for a slightly richer twist.
INGREDIENTS:
3 pounds russet potatoes or other starchy baking potatoes, peeled and quartered
1 white onion, diced, or 2 leeks, thinly sliced and well rinsed
½ head green cabbage (about 6 cups), chopped into bite-size pieces
½ cup half-and-half or heavy whipping cream, gently warmed
¼ cup salted butter
3 tablespoons melted butter, for finishing
Salt and freshly ground black pepper, to taste
Optional additions:
4–6 slices bacon, cooked crisp and chopped
1 pound parsnips (to replace part of the potatoes)
METHOD:
Place the peeled and quartered potatoes in a large pot and cover with cold, well-salted water. Bring to a boil, then reduce to a gentle simmer and cook for 12–15 minutes, or until the potatoes are fork-tender.
While the potatoes cook, dice the onion into roughly ½-inch pieces, or thinly slice the white and light green portions of the leeks. Rinse leeks well to remove any grit. Chop the cabbage into bite-size pieces.
Melt the ¼ cup butter in a large skillet over medium heat. Add the onion or leeks and cook for several minutes until softened. Stir in the cabbage and cook, stirring occasionally, until the vegetables are tender and lightly sweet, about 8–10 minutes.
Drain the cooked potatoes well and return them to the warm pot. Mash with a potato masher or potato ricer. Gradually stir in the warmed cream and 3 Tablespoons melted butter until the potatoes are smooth and fluffy. Season generously with salt and black pepper.
Gently fold the sautéed cabbage and onions into the mashed potatoes. Taste and adjust seasoning as needed.
Transfer to a serving bowl and create a small well in the center for additional melted butter, if desired.
VARIATIONS:
- Replace about 1 pound of the potatoes with peeled parsnips for a subtle sweetness that pairs beautifully with cabbage.
- For a richer version, cook 4–6 slices of bacon until crisp. Remove the bacon and sauté the onion and cabbage in the bacon drippings with a small amount of butter. Fold the chopped bacon into the finished potatoes.
- Traditional colcannon is often made with cabbage, but curly kale or savoy cabbage also work well. Kale adds a slightly earthier flavor.
- Russet potatoes produce the fluffiest mash, but Yukon Gold potatoes create a slightly richer texture and flavor.
- While not traditional, a spoonful of sour cream or cream cheese can be stirred into the potatoes for additional creaminess.
