Colcannon is a traditional Irish dish made by combining creamy mashed potatoes with cooked cabbage or kale and rich butter. It’s warm, simple, and filling—the kind of food that brings comfort with every bite. Colcannon is usually served as a side dish, especially on St. Patrick’s Day or during colder months, but it’s hearty enough to stand on its own with a fried egg on top or a slice of ham on the side. This recipe serves 4.
Ingredients
-
4 large potatoes (Yukon Gold or Russet), peeled and chopped
-
1/2 small head of green cabbage (or 2 cups chopped kale), finely shredded
-
1/2 cup whole milk (or plant-based milk for dairy-free)
-
1/4 cup unsalted butter, plus more for serving
-
4 green onions (spring onions), thinly sliced
-
Salt and black pepper to taste
How to Make Colcannon
Step 1: Cook the potatoes
Place the peeled, chopped potatoes in a large pot of salted water. Bring to a boil and cook for about 15–20 minutes or until the potatoes are fork-tender.
Step 2: Cook the cabbage or kale
While the potatoes are cooking, melt a tablespoon of butter in a pan over medium heat. Add the shredded cabbage (or kale) and a pinch of salt. Cook for 5–7 minutes until tender. Stir in the green onions and cook for 1–2 more minutes. Set aside.
Step 3: Mash the potatoes
Drain the potatoes well and return them to the pot. Add the remaining butter and the warm milk. Mash until smooth and creamy.
Step 4: Combine
Fold the cooked cabbage and green onions into the mashed potatoes. Mix well. Taste and adjust with salt and pepper.
Step 5: Serve
Spoon into bowls or onto plates, and make a small well in the center of each serving. Drop in a little knob of butter and let it melt into the hot potatoes before eating.
Serving Suggestions
Colcannon pairs well with roasted meats, sausages, baked ham, or even a poached egg. It also works great as a vegetarian main with just a slice of hearty bread.
Colcannon is rustic, comforting, and packed with flavor from the buttery potatoes and tender greens. It’s proof that simple ingredients can create something deeply satisfying.
