Steam parsnips, carrots and rutabaga over boiling water for 6 minutes, until half cooked. Alternatively, place vegetables in a microwavable dish with 1/2 inch water, cover loosely and microwave for 4 minutes.
Preheat oven to 375°F. Drain vegetables and toss with thyme, olive oil, lemon juice, pepper and salt. Spread on a rimmed baking sheet lined with parchment paper and roast for 35 minutes, until vegetables are caramelized and tender.
