2-3 cups cubed (½” cubes) parsnips, carrots, beets, turnips, radishes, potatoes, sweet potatoes, apples, onions, celeriac, parsley root. Just about any combination is delicious. If using large beets, throw them into the microwave for a few minutes to soften them since they are denser than the other vegetables. Red beets will stain the hash, so golden or Chioggia beets will make a more attractive dish. 

2 T. good quality olive oil

1 clove garlic, minced

Preheat the oven to 375. Toss the vegetables with the olive oil and garlic. Spread in a single layer on a roasting pan or cookie sheet with sides. Or use a cast iron pan as long as you can make only one layer. Roast about 15 minutes and then stir. Roast another 15-20 minutes until vegetables are tender when pierced with a fork and beginning to brown. Remove from oven and salt and pepper liberally.
