This is an Irish dish so I wanted to make it for St. Patrick's day. It is really unique and my kids didn't like it but I thought it was good. I thought maybe I could conceal the cabbage but that really didn't happen.... so if you don't like cabbage you probably wouldn't like this, but if you're looking for a new potato dish and like cabbage - give it a try!
Colcannon
6 large potatoes, peeled
6-8 T. half-and-half (or milk)
1 tsp kosher salt
1 onion, finely chopped
6 T. butter, divided
1/2 of a small head of cabbage, sliced thinly
1. Slice peeled potatoes into small chunks and place in pot. Fill pot with water an inch above potatoes and boil until soft. While the potatoes are cooking, melt 4 T. butter in large saucepan. Add minced onion and stir to coat with butter. Add cabbage over onions. Cover saucepan and cook over med-low to medium heat for 20 minutes, stirring occasionally, or until cabbage is soft.
2. Drain potatoes and add half-and-half (or milk) and salt. Mash with electric mixer. Stir together onion and cabbage mixture with mashed potatoes. Spoon into an oven safe dish and place under broiler until top is browned. After you pull it out of the oven, top Colcannon with the rest of the butter and allow it to melt on top as it sits.
