I’ll admit I don’t know too much about Irish cooking, but I do know the Irish can make incredibly flavorful and satisfying food from simple ingredients, and no one is better with potatoes. Champ is so deceptively simple; you won’t believe the rich flavor. Add this to any meal and it’s instantly a simple St. Patrick’s celebration.
Irish Mashed Potatoes with Green Onions
6 green onions (about 3 ounces)
2 pounds russet potatoes (about 3 large)
2 cups buttermilk
¼ cup (1/2 stick) butter
Melted butter for drizzling
Slice the white, light green and a small bit of the dark green part of the green onions very finely. Save the rest of the dark green part for garnish. Peel the potatoes and slice into chunks. Place in a large pan and just cover with water. Add half the sliced green onions. Bring to a boil and boil until the potatoes are very tender, about 15 minutes. Drain the potatoes and green onions in a colander, shaking out the water, then return to the pot. Place a tea towel over the pot, the cover tightly with the lid. Leave for 10 minutes.
Meanwhile, heat the buttermilk with the remaining green onions and the butter over low heat until the butter is melted and the mixture is warmed through.
Uncover the potatoes and begin mashing. Pour in the buttermilk mixture and mash until smooth, adding salt to taste. The mixture will be quite loose. Scrape the potatoes into a small baking dish, smoothing the top. You can keep the potatoes covered for a few hours at this point, or just move on to the baking.
When ready to serve, heat the oven to 350 degrees. Bake until heated through, about 20 minutes. Let rest for 5- 10 minutes before serving. Drizzle with melted butter and sprinkle with chopped green onion tops to serve.
