Ingredients

  • 1 tablespoon butter + extra for serving
  • 1 tablespoon olive oil
  • 1/2 medium onion chopped
  • 1/2 medium cabbage (about 3 cups) OR use kale chopped
  • 2.5 pounds Russet potatoes cut into chunks
  • 1/2 cup water
  • 1/2 cup heavy/whipping cream
  • Salt & pepper to taste
  • Chives or scallions chopped, to taste

Instructions

  1. Add the butter and oil to the Instant Pot. Sauté the onion for 2-3 minutes, then add the cabbage and continue to cook until it starts to wilt (another few minutes). 

  2. Add the potatoes and water to the Instant Pot. Close the lid and make sure the valve is on "sealing". Cook on high pressure for 5 minutes.

  3. Carefully do a quick pressure release. Test to make sure the potatoes are done by inserting a knife. If they're not done, put the lid back on and cook them on high pressure for another couple minutes.

  4. You can mash the potatoes right in the inner pot on your counter (I don't like to mash them with the inner pot in the pressure cooker in case I damage the heating element). Add the cream, salt & pepper (I'm pretty generous), and chives. Mash until the colcannon is the consistency you like. Serve with butter on top. 

Recipe Notes

  • Serves 4-6.
  • Inactive time indicates the amount of time it takes the Instant Pot to get up to pressure.
  • I tested this recipe both with cabbage and kale, and I prefer the taste and texture of the cabbage.
