Preheat your oven to 425°F (220°C).
Wash and peel the carrots, then trim both ends.
Cut the carrots into even-sized pieces for uniform cooking.
In a large bowl, toss the carrots with olive oil, salt, pepper, garlic powder, and rosemary.
If using honey, drizzle it over the carrots and mix well.
Spread the carrots in a single layer on a baking sheet.
Roast in the oven for 25-30 minutes, stirring halfway through.
Check for tenderness by piercing with a fork; they should be soft and caramelized.
Once done, remove from the oven and let cool slightly.
Serve warm and enjoy your delicious oven roasted carrots!
