A creamy and comforting Irish dish where buttery mashed potatoes are folded with tender wilted cabbage or kale and green onions. This hearty side dish is perfect for weeknight dinners or festive holiday tables.

Ingredients

Scale
  • 3 pounds russet or Yukon Gold potatoes, peeled and cut into large chunks
  • 1 large head of green cabbage or kale, finely shredded (about 8 cups packed)
  • 1 cup whole milk, warmed
  • 1/2 cup (1 stick) unsalted butter, divided
  • 4 green onions (scallions), thinly sliced
  • Salt and freshly ground black pepper, to taste

Instructions

  1. Place potato chunks in a large pot and cover with cold, salted water by about an inch. Bring to a boil over high heat, then reduce to a simmer. Cook for 15-20 minutes, or until fork-tender.
  2. While potatoes cook, melt 4 tablespoons of the butter in a large skillet or Dutch oven over medium heat. Add shredded cabbage or kale and a big pinch of salt. Cook, stirring occasionally, for 10-12 minutes until greens are very tender.
  3. Stir sliced green onions into the cooked greens during the last 2 minutes of cooking. Remove from heat.
  4. Drain cooked potatoes well and return them to the hot pot. Let them steam dry off the heat for a minute.
  5. Add remaining 4 tablespoons of butter to potatoes and begin mashing. Gradually pour in warm milk, mashing until desired consistency is reached.
  6. Gently fold the buttery cabbage and green onion mixture into the mashed potatoes until evenly distributed.
  7. Taste and season generously with salt and black pepper. Serve warm.

Notes

For a dairy-free version, use plant-based butter and unsweetened oat or almond milk. To prevent gluey potatoes, avoid over-mashing and use a hand masher. Salt the potato cooking water well for best flavor. Leftovers reheat well with a splash of milk.
