- 8 to 12 slender carrots, peeled and trimmed
- 8 to 12 baby turnips, peeled
- 6 to 8 fingerling potatoes, scrubbed and cut lengthwise in halves
- 1 or 2 large parsnips, peeled, trimmed, and cut diagonally into 1-inch-thick slices
- 1 or 2 medium onions, trimmed, peeled and halved, each 1/2 cut into quarters
- 1 or 2 large beets, peeled and cut into thick wedges
- 1 or 2 kohlrabi bulbs, peeled and cut into thick wedges
- 1 celery root, trimmed and halved, halves cut crosswise into 1-inch-thick slices
- 1 whole head garlic, separated into cloves, unpeeled
- 2 or 3 sprigs fresh rosemary, sage, or thyme
- Freshly ground black pepper
- Extra-virgin olive oil
Preheat the oven to 400 degrees F.
Put all the vegetables and the herb sprigs in a large baking dish. Season well with salt and black pepper, drizzle generously with olive oil, and toss them with your hands to coat them evenly.
Put the baking dish in the preheated oven and cook, stirring the vegetables occasionally, until they are tender and golden brown, about 45 minutes. Serve the vegetables from their baking dish or transfer them to a platter to accompany a roasted main course.
