4.5 from 79 reviews

Colcannon is a traditional Irish comfort dish featuring creamy mashed potatoes combined with sautéed cabbage and onions or leeks. This hearty and flavorful side is perfect for cozy meals, offering a wonderful blend of buttery richness and tender vegetables.

Ingredients

Scale

Potatoes

  • 3 pounds russet potatoes (or baking potatoes), peeled and quartered

Vegetables

  • 1 white onion (or 2 leeks)
  • ½ head green cabbage (about 6 cups), cut into 1-inch pieces

Dairy & Fats

  • ½ cup half and half (or heavy whipping cream), warmed
  • ¼ cup salted butter
  • 3 tablespoons salted butter, melted (for folding and topping)

Seasonings

  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Boil Potatoes: Bring a large pot of salted water to a boil. Add the peeled and quartered potatoes and simmer for 12-15 minutes, or until they are fork-tender.
  2. Prepare Vegetables: While the potatoes cook, dice the white onion into ½-inch pieces. If using leeks, slice the white and light green parts thinly and rinse well to remove any grit. Cut the cabbage into 1-inch pieces.
  3. Sauté Onions and Cabbage: Melt ¼ cup of butter in a large skillet over medium heat. Add the diced onions or leeks along with the cabbage, cooking until the onions become translucent and the cabbage is tender, about 8-10 minutes.
  4. Mash Potatoes: Drain the cooked potatoes and return them to the warm pot. Using a potato masher, mash the potatoes while gradually adding the warmed half and half and 3 tablespoons of melted butter. Season with salt and black pepper according to taste.
  5. Combine Ingredients: Gently fold the sautéed cabbage and onions or leeks into the mashed potatoes, ensuring the mixture is well incorporated but not overmixed to maintain texture.
  6. Serve: Transfer the colcannon to a serving dish and top with additional melted butter if desired for extra richness. Serve warm as a comforting side dish.

Notes

  • If desired, substitute leeks for onions for a milder, sweeter flavor.
  • Use salted butter to add seasoning; adjust additional salt accordingly.
  • Warm the cream before adding to the potatoes to keep them hot and ensure smooth mashing.
  • Colcannon pairs well with roasted meats, sausages, or as part of a traditional Irish meal.
  • Leftovers can be refrigerated for up to 3 days and reheated gently to maintain creamy texture.
