Preheat your oven to 425°F (220°C).
Wash and peel the carrots, then cut them into even-sized sticks.
In a large bowl, toss the carrot sticks with olive oil, salt, and black pepper.
Spread the carrots in a single layer on a baking sheet.
Roast in the preheated oven for 25-30 minutes, stirring halfway through.
Check for tenderness; they should be caramelized and fork-tender.
Remove from the oven and let them cool for a few minutes.
Garnish with fresh thyme if desired.
Serve warm, or allow to cool completely for later use.
Enjoy your delicious oven roasted carrots!
