Preheat the oven to 400°F (200°C).
In a mixing bowl, whisk together melted butter, honey, garlic, salt, pepper, and thyme.
Toss the carrots in the mixture until evenly coated.
Spread the carrots in a single layer on a baking sheet.
Roast for 25-30 minutes, stirring halfway through, until tender and caramelized.
Garnish with fresh parsley and serve warm.
