Honey-Roasted Root Vegetables

1. Preheat the oven to 400°F. Cook the honey in a large heavy skillet over medium heat until it is thick and dark with large bubbles, about 10 minutes. Stir in the carrots, parsnips, turnips, rutabagas, and onions and cook until the vegetables are deeply glazed, 8 to 10 minutes.

2. Transfer the skillet to the oven and roast until the vegetables are tender and well caramelized, 15 to 20 minutes. (Alternatively, continue cooking and tossing the vegetables on the stove top until they are tender and well glazed, about 25 minutes.)

3. Stir in the butter, lemon juice, and thyme, if using. Season to taste with salt and pepper. (To make ahead, cool then refrigerate in a covered container for up to 2 days. Reheat in a skillet over medium heat, stirring frequently to prevent scorching.)

4. Transfer to a warm platter and decorate with large sprigs of the thyme, if you wish.
