In a medium-sized bowl, whisk together the olive oil, honey and thyme, if using. Whisk in salt and pepper to taste. Add the carrots and parsnips, stirring to coat the vegetables.
Spread the vegetables evenly on a baking sheet, drizzle any remaining liquid on top, and roast for 25-30 minutes, stirring halfway through, until tender and lightly caramelized. Sprinkle with more salt and pepper if desired.

Notes
Storage SuggestionsYou can store leftovers in an airtight container in the fridge for up to 4 days. They reheat well and make a great little add-on to lunches or grain bowls! You can warm them in the microwave, but if you want to bring back a bit of that roasted texture, pop them in a 375°F oven for about 10 minutes.
