Pimped Root Vegetable Hash

1 pound parsnips, peeled and cut into 1/2-inch pieces

1 pound sweet potatoes, peeled and cut into 1/2-inch pieces

2 T. extra-virgin olive oil

1 large onion, chopped

Salt

Freshly ground black pepper

8 ounces cheddar cheese, shredded (2 C.)

Preheat the oven to 4OO°F. Combine the parsnips and sweet potatoes in a medium saucepan and add cold water to cover. Bring to a simmer and cook until both vegetables are firm-tender (just shy of al dente), about 10 minutes. Drain the vegetables and set aside. Meanwhile, heat 1 T. of the oil over medium-high heat in a large ovenproof skillet (such as cast iron). Add the onions, salt and pepper to taste, and cook, stirring occasionally, until soft and charred in places, about 15 minutes. Transfer the onions to a bowl. Add the remaining T. of oil to the pan. When hot, add the vegetables and cook until browned in spots, turning just once or twice, about 10 minutes. (If you fiddle with the vegetables too much, they’ll stick, so seriously, hands off.) Spread the onions over the vegetables, then top with the cheese, and bake for 5 to 10 minutes, or until the cheese is completely melted and beginning to bubble. Serve hot.
