This comforting Irish dish blends creamy mashed potatoes with tender cabbage and fresh scallions. Potatoes are boiled until soft, cabbage is lightly cooked to retain gentle texture, and scallions add a subtle onion flavor. Warm milk and butter enrich the mash, creating a smooth, flavorful side that's perfect alongside hearty mains. Simple preparation and familiar ingredients make it a beloved classic from Ireland.
The first time I encountered colcannon was in a tiny pub in Cork where the bartender's mother had dropped off a massive pot earlier that afternoon. Steam was still rising from the bowl when it hit the table, carrying this incredible aroma of butter and cooked cabbage that made my stomach growl instantly. I've been making it ever since, tweaking the method until the potatoes turn impossibly fluffy and the cabbage melts into them like it was always meant to be there.
Last winter my neighbor came over while I was mashing the potatoes and stood in my kitchen doorway just breathing in the smell. She ended up staying for dinner and we ate it straight from the pot while watching the snow fall outside the window. That night taught me this dish is meant for sharing.
Ingredients
- Floury potatoes: Yukon Gold or Russet potatoes work best here because they break down beautifully and absorb all that buttery milk without turning gluey
- Green cabbage: You want to shred it finely so it practically disappears into the mash, leaving just subtle sweetness and texture
- Scallions: These add a mild onion bite that cuts through all that richness
- Whole milk and unsalted butter: Heating them together before mixing creates the most luxurious, creamy base imaginable
Instructions
- Get your potatoes started:
- Cover peeled cubed potatoes with cold salted water and simmer until they surrender completely to a fork, about 15 to 20 minutes
- Blanch the cabbage:
- Drop shredded cabbage into boiling salted water for just 4 to 5 minutes, then drain it thoroughly so your mash does not turn watery
- Warm the dairy:
- Gently heat milk and butter together until melted but do not let it come to a boil
- Mash like you mean it:
- Drain those potatoes completely and mash until they are smooth and airy
- Bring it all together:
- Fold in the warm milk mixture followed by the cabbage and scallions, then season generously
My sister served this at her wedding reception and guests kept asking what was in the mash. Something about the combination of humble ingredients transforming into something extraordinary really resonates with people.
Getting the Texture Right
A potato ricer gives you the fluffiest results but a good old fashioned masher works perfectly fine if you are patient. The key is working quickly while the potatoes are still hot so they absorb all that dairy.
Make Ahead Magic
You can cook the cabbage and potatoes up to a day in advance. Just reheat everything gently with a splash more milk before serving.
Serving Suggestions
This mash pairs beautifully with bangers, corned beef, or any roasted meat. I have also been known to eat a bowl of it on its own for a late night snack.
- Top with an extra knob of butter that melts into all the crevices

- Keep it warm in a low oven until ready to serve
Simple food made with care has a way of becoming the stuff memories are made of. Enjoy every bite.
