Preheat the oven to 400ºF. Peel or scrub the carrots, then cut them into one-inch sections.
Place the carrots onto a parchment-lined baking sheet. Drizzle the olive oil over top, then season with salt, pepper, and garlic powder. Toss the carrots until they are well coated in oil and spices.
Roast the carrots in the preheated oven for 20 minutes, then give them a good stir. Roast for an additional 10-15 minutes, or until they reach your desired level of browning.
Taste the carrots and adjust the salt or pepper to your liking. Serve hot and enjoy!
