Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

In a large mixing bowl, combine the peeled and cut carrots. Drizzle with olive oil and honey, then sprinkle with thyme, salt, and pepper. Add balsamic vinegar if desired.

Toss the carrots until evenly coated in the honey and olive oil mixture.

Spread the coated carrots in a single layer on the prepared baking sheet.

Roast the carrots for 20-25 minutes, stirring halfway through for even cooking.

Optional: Add butter during the last 5 minutes of roasting for extra richness.

Adjust seasoning with more salt and pepper after roasting.

Garnish with additional thyme before serving.
