Carefully peel rutabaga with a paring knife. Cut rutabaga into one-inch pieces.
Place in a medium-sized pan. Cover with enough water and bring to a boil over medium-high heat on the stovetop.
Boil until fork tender, about 15 minutes or so.
Drain cooked rutabaga. Add the butter and milk, season with a generous pinch of salt and black pepper. Serve warm.
Notes
Rutabagas from the grocery store or farmers market have a waxy coating that need to be removed. The coating it to keep the rutabagas from drying out.You can use a good vegetable peeler or a pairing knife to peel the skin off. I use a knife because the skin is tough.
