Creamy Irish Colcannon with Cabbage and Onions Recipe
Introduction
Colcannon is a traditional Irish dish that combines creamy mashed potatoes with tender cabbage and onions. It’s simple, comforting, and perfect as a hearty side for any meal.

Ingredients
- 3 pounds russet potatoes (or baking potatoes, peeled & quartered)
- 1 white onion (or 2 leeks)
- ½ head green cabbage (about 6 cups)
- ½ cup half and half (or heavy whipping cream, warmed)
- ¼ cup salted butter (plus 3 melted tablespoons)
- Salt and black pepper (to taste)
Instructions
- Step 1: Bring a large pot of salted water to a boil. Add the potatoes and simmer for 12-15 minutes or until fork-tender.
- Step 2: While the potatoes are cooking, prepare the onion or leeks and cabbage. Dice the white onion into ½-inch pieces or slice the white and light green parts of the leeks thinly and rinse well. Cut the cabbage into 1-inch pieces.
- Step 3: Melt ¼ cup of butter in a large skillet over medium heat. Cook the onion or leeks and cabbage in the butter until the onion is translucent and the cabbage is tender.
- Step 4: Once the potatoes are cooked, drain them and return them to the warm pot. Mash the potatoes with a potato masher, adding the warmed cream and 3 tablespoons melted butter. Season with salt and pepper.
- Step 5: Gently fold the mashed potatoes, cabbage, and onions together until well combined.
- Step 6: Serve topped with additional melted butter if desired for extra richness.
Tips & Variations
- For a milder flavor, substitute green cabbage with savoy cabbage or kale.
- Add chopped scallions or chives for a fresh, oniony kick.
- Use chicken or vegetable broth instead of cream if you prefer a lighter version.
- Leftover colcannon can be shaped into cakes and fried for a delicious twist.
Storage
Store colcannon in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it in a skillet over low heat or microwave until heated through, adding a splash of cream or milk to restore creaminess.

Ingredients
Potatoes
- 3 pounds russet potatoes (or baking potatoes), peeled and quartered
Vegetables
- 1 white onion (or 2 leeks)

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

Instructions
- 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.

- 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.
- 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.
- 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.
