Colcannon is a traditional Irish dish made with mashed potatoes and either kale or cabbage. This version is made in the Instant Pot for a quick and easy side dish for St. Patrick’s Day.
Set Instant Pot to saute. Add butter and let melt. Add cabbage and onions. Cook 5 minutes, stirring occasionally, until softened. Add potatoes and water and season with salt and pepper.
Place lid on Instant Pot and set valve to sealing. Cook on high pressure 5 minutes (Instant Pot will take 10 minutes to come up to pressure before counting down). When done cooking, quick release pressure.
