This dish features creamy mashed potatoes mixed with sautéed shredded cabbage and scallions, all combined with melted butter and warm milk for a silky texture. The cabbage adds a subtle sweetness and crunch, while the butter enriches the dish with a smooth, velvety finish. It's an iconic Irish comfort side that pairs beautifully with roasted meats or vegetarian fare. Quick to prepare and naturally gluten-free and vegetarian, it's a versatile addition to any meal.

The steam still rising from the bowl takes me back to a tiny Dublin kitchen where I first watched someone make colcannon by feel rather than recipe. My host kept saying the secret was in how you treated the cabbage, and honestly, she was right. That first spoonful changed everything I thought I knew about mashed potatoes.

Last St. Patricks Day, I made this for friends who were skeptical about cabbage in their mashed potatoes. By the end of dinner, they were asking for the recipe, and the serving bowl was completely empty. Sometimes the simplest conversions are the most satisfying to watch happen.

Ingredients

  • Russet or Yukon Gold potatoes: These varieties mash up fluffy and absorb the butter beautifully
  • Green cabbage: Finely shredded so it softens quickly and blends seamlessly into the potatoes
  • Scallions: Their mild onion flavor brightens the whole dish without overpowering
  • Unsalted butter: You need a generous amount here, seriously do not skimp
  • Whole milk: Warmed before adding creates the silkiest texture imaginable
  • Salt and pepper: Season aggressively at every stage for the best flavor

Instructions

Start your potatoes:
Place them in cold, salted water and bring to a gentle boil
Soften the cabbage:
Sauté it in butter until it just starts to wilt, then add scallions
Drain and steam:
Let the potatoes sit in the hot pot for a minute to evaporate excess moisture
Mash thoroughly:
Work them until completely smooth before adding anything else
Warm your dairy:
Heat the milk and remaining butter together until melted
Combine everything:
Fold the cabbage mixture gently into the creamy potatoes

My grandmother would always make a little well in the center of her colcannon and fill it with melted butter. We called it the butter pool, and getting a spoonful with extra butter was basically winning the dinner lottery. Small traditions like that stick with you.

Making It Your Own

Leeks work beautifully here if you want something milder than scallions. I have also stirred in chopped parsley at the end for a pop of fresh color that makes the dish feel more vibrant on the plate.

Serving Suggestions

This pairs perfectly with roasted lamb or alongside sausages for a proper Irish feast. The creamy texture also balances nicely with something acidic like a vinegary slaw or pickled vegetables on the side.

Getting Ahead

You can prepare the cabbage mixture hours ahead and just reheat it gently before folding in. The potatoes really are best made right before serving, but you can peel and cut them earlier, just keep them submerged in cold water so they do not discolor.

  • Keep leftover butter at room temperature for that final melt on top
  • Warm your serving bowl in the oven while you cook
  • Extra scallions on top never hurt anyone
