Preheat your oven to 400 degrees Fahrenheit.
Peel the carrots and cut them into 2-inch segments. Then, quarter or cut into sixths lengthwise depending on size.
Chop the thyme and set aside.
Oil a sheet pan or baking dish large enough to fit all the carrots in a single layer.
In a large bowl, toss the carrots with olive oil, salt, pepper, thyme, and oregano until evenly coated.
Spread the seasoned carrots in an even layer on the prepared pan or baking dish. Cover with foil.
Place in the preheated oven and roast for 20 to 30 minutes.
After the initial roasting time, uncover the carrots. If they're not tender yet, reduce the oven temperature to 375 degrees Fahrenheit and roast for an additional 5 to 10 minutes.
Once the carrots are tender, remove from the oven and sprinkle with chopped parsley. Gently stir to combine.
Taste and adjust seasoning with salt and pepper if needed.
Serve the roasted carrots hot, warm, or at room temperature.
