What is Colcannon?

If you’ve never heard of Colcannon be prepared for something delicious! This traditional Irish recipe combines potatoes, kale or cabbage, butter and milk for a creamy and delicious side dish.

Key Ingredients for this Instant Pot Colcannon:

  • Potatoes: I used Russet potatoes for this recipe, but you could use whatever variety of potatoes you prefer for mashed potatoes, like Yukon gold and red potatoes.
  • Cabbage: We prefer the cabbage version of colcannon, but you could sub for kale too.
  • Onion: Onion adds lots of great flavor, but isn’t 100% necessary to a delicious colcannon if you don’t have on hand.
  • Dairy: Milk and butter are a must for rich, creamy mashed potatoes.

Nutrition Tip: It may look like iceberg lettuce, but cabbage is not a nutritional lightweight! It’s a surprising source of vitamin C, contains a little bit of calcium and potassium, and has cancer-fighting compounds like broccoli.
