This classic Irish dish is a must for St. Patrick's Day. Traditional Colcannon is floury mashed potatoes mixed with butter and kale (or cabbage). It's serious comfort food.
Although it's very popular during St Patrick's Day, this Irish side dish is popular year round.

🔄 Substitutions and Variations
- Other greens - instead of the curly kale (which is what I used in the images) you could use a savoy cabbage, white-headed cabbage or a green cabbage.
- Bacon Grease - try cooking the cabbage/kale in some bacon grease for tons of flavor. Plus you'll have some crisp bacon you could add a little to this traditional Irish side dish. Or save it for later.
- Irish Bacon - you could add a little to the dish.
- Potatoes - I recommend using a more floury potato, like the russet or King Edward - but if you're in a pinch, or only have one of these, they'll do. Red potatoes or Yukon gold potatoes will work.
- Heavy Cream - instead of milk.
- Cheddar Cheese - for another flavor profile.
- Sour Cream - to add some richness.

Expert Tip: A more floury potato, like the russet, is preferable in this recipe. A waxy potato will not give as good a result.
