Preheat oven to 220°C (425°F). Line a large baking sheet with parchment paper.
Peel the carrots and cut diagonally into 1.5cm (1/2 inch) thick pieces, keeping all pieces uniform in size.
In a large bowl, combine olive oil, honey, minced garlic, salt, pepper, and thyme. Add carrots and toss until every piece is evenly coated.
Spread carrots in a single layer on the baking sheet with visible space between each piece. Pour any remaining glaze from the bowl over the top.
Roast on the middle rack for 12 minutes. Flip each piece with tongs, then roast for another 10 to 13 minutes until tender through the center when pierced with a fork and edges are golden brown.
Transfer to a serving plate, scatter fresh parsley on top, and serve immediately.
